Four ways we help trim your tax bill
And why these "invisible" wins matter more than you may think.
Four ways we help trim your tax bill And why these "invisible" wins matter more than you may think. As investors, we tend to focus most on what we can see. Things like portfolio makeup, and the returns generated by those investments. No less important, however, are the less obvious things, like the taxes you never paid in the first place because of technology that quietly runs in the background. You may only think about taxes once a year, but here at Betterment, every day is Tax Day. This sort of year-round tax optimization sounds boring, but believe us, it makes a difference. Taxes can steadily eat away at your returns over the years. So any advisor worth their salt should take taxes seriously and minimize them as much as possible. These “invisible” wins are hard to spot in the moment, so let’s shine a light on them now. Here are four sophisticated ways we buy, sell, and hold your shares, all in the name of trimming your tax bill. Choosing which assets go where – Our Tax Coordination feature helps shield high-growth assets in the most tax-efficient account types. Rebalancing wisely – After rebalancing target allocations for cash holdings, we take advantage of any available cash flows to help minimize capital gains taxes while rebalancing your portfolio. Choosing which taxable shares to sell (or donate) – Our TaxMin technology helps minimize short-term capital gains taxes. Harvesting losses – When your taxable investments dip below their initial purchase price, we jump on the opportunity to “harvest” the theoretical loss and potentially lower your future tax bill. 1. Choosing which assets go where From a tax perspective, you have three main account types at your disposal when saving for retirement: Tax-deferred (traditional IRAs, 401(k)s, etc.), where taxes are paid later. Tax-exempt (Roth IRAs, 401(k)s, etc.), where taxes are paid now. Taxable, where taxes are paid both now and later. Because of their different tax treatments, certain types of investments are a better fit for certain accounts. Interest from bonds, for example, is typically taxed at a higher rate than stocks, so it often makes sense to keep them away from taxable accounts. This sorting of asset types based on tax treatments, rather than divvying them up equally across accounts, is known as asset location. And our fully-automated, mathematically-rigorous spin on it is called Tax Coordination. When Tax Coordination is turned on, the net effect is more of your portfolio's growth is shielded in a Roth account, the pot of money you crucially don't pay taxes on when withdrawing funds. To learn more about our Tax Coordination feature and whether it’s right for you, take a peek at its disclosure. 2. Rebalancing wisely When the weights of asset classes in your portfolio drift too far from their targets, our technology automatically brings them back into balance. But there's more than one way to accomplish this portfolio rebalancing. You can simply sell some of the assets that are overweight, and buy the ones that are underweight (aka "sell/buy" rebalancing), but that can realize capital gains and result in more taxes owed. So we take advantage of any available cash flows coming into or out of your portfolio. When you make a withdrawal, for example, we first rebalance any applicable target allocation for cash, then we intentionally liquidate overweight assets while striving to minimize your tax hit as much as possible (more on that below). 3. Choosing which taxable shares to sell (or donate) Say there's no way around it: you need to sell an asset. Maybe cash flows aren't enough to keep your portfolio completely balanced. Or you’re withdrawing funds for a major purchase. The question then becomes: which specific assets should be sold? The IRS and many brokers follow the simple script of "first in, first out," meaning your oldest assets are sold first. This approach is easier for your broker, and it can avoid more highly-taxed short-term capital gains. But it often misses the opportunity of selling assets at a loss, and harvesting those losses for potential tax benefits. So our algorithms take a more nuanced approach to selecting shares, and we call this technology TaxMin. TaxMin is calibrated to avoid frequent small rebalance transactions and seek tax-efficient outcomes, things like helping reduce wash sales and minimizing short-term capital gains. In the case of donating shares, we apply the same logic in reverse, or TaxMax as we call it. That's because when donating shares, it benefits you to choose the ones with the most gains, since any shares bought as a replacement will effectively have a reset tax bill. 4. Harvesting losses Life is full of ups and downs, and your investments are no different. At times, most notably during market downturns, the price of an asset may dip below what you paid for it. Our tax-loss harvesting takes advantage of these moments, selling taxable assets that fit this bill. We then use available funds to buy similar investments to replace those we sold, making adjustments to rebalance your portfolio. You can then use those harvested losses to shift taxes you owe now into the future. The strategy doesn’t make sense for everyone, but it can help some investors sprinkle tax advantages on a portion of their taxable investing. And our fully-automated spin on it takes a tax hack once reserved for the wealthy and makes it available to the masses. Happy harvesting. In conclusion, we care a lot about taxes Because it’s one of the most reliable ways to boost your returns. We can’t control the market, but tax laws? Those are set by the IRS and broadcast far and wide. And we can help you navigate them wisely. We wouldn’t be doing our job if we didn’t. So the next time you take a peek at your returns, ask yourself how much of that growth will still be there come tax time. If you’re a Betterment customer, you can rest assured we’re working tirelessly to minimize those tax drags. You may not realize it right away, and rightfully so. Live your life, and leave the tax toiling to us. -
How our Tax Coordination feature can boost your returns
Our spin on asset location can help shelter retirement investment growth from some taxes.
How our Tax Coordination feature can boost your returns Our spin on asset location can help shelter retirement investment growth from some taxes. Taxes. You may try to think of them as little as possible, but they’re on our minds a lot. Especially when they relate to investments. That’s because we’re always looking to maximize our customers’ potential take-home returns—and key to that pursuit is minimizing how big of a bite taxes take. On that front, our Tax Coordination feature is a fully-automated approach to an investment strategy known as asset location—and it’s available at no additional cost. If you’re saving for retirement in more than one type of account, then asset location in general, and our spin on it specifically, can help to increase your after-tax expected returns without taking on additional risk. Here’s how. How Tax Coordination works Many Americans wind up saving for retirement in some combination of three account types: Taxable Tax-deferred (Traditional 401(k) or IRA) Tax-exempt (Roth 401(k) or Roth IRA) Each type of account gets a different tax treatment, and different assets are taxed differently as well. These rules make certain investments a better fit for one account type over another. Returns in IRAs and 401(k)s, for example, don’t get taxed annually, so they generally shelter growth from tax better than a taxable account. We’d rather shield assets that lose more to tax in these types of retirement accounts, assets such as bonds, whose dividends are usually taxed annually and at a high rate. In the taxable account, however, we’d generally prefer to have assets that don’t get taxed as much, assets such as stocks, whose growth in value (“capital gains”) is taxed at a lower rate and crucially only when they’re “realized,” or in other words, when they’re sold at a higher price than what you paid for them. Wisely applying this strategy to a globally-diversified portfolio can get complicated quickly. Check out our full Asset Location methodology if you’re curious what that complexity looks like—or keep reading for more of the simplified explanation. The big picture diversification of asset location When investing in more than one account, many people select the same portfolio in each one. This is easy to do, and when you add everything up, you get the same portfolio, only bigger. To illustrate this approach, here’s what it looks like with a hypothetical asset allocation of 70% stocks and 30% bonds. The different shades of green represent various types of stocks, and the different shades of blue represent various types of bonds. But as long as all the accounts add up to the portfolio we want, each individual account on its own doesn’t have to mirror that portfolio. Each asset can go in the account where it makes the most sense from a tax perspective. As long as we still have the same portfolio when we add up the accounts, we can increase the after-tax expected return without taking on more risk. This is asset location in action, and here’s what it looks like, again for illustrative purposes: This is the same overall portfolio as we originally showed, except we redistributed the assets unevenly to reduce taxes. Note that the aggregate allocation is still a 70/30 split of stocks and bonds. The concept of asset location isn’t new. Advisors and sophisticated do-it-yourself investors have been implementing some version of this strategy for years. But squeezing it for more benefit is very mathematically-complex. It means making necessary adjustments along the way, especially after making deposits to any of the accounts. Our expert-built technology handles all of the complexity in a way that a manual approach just can’t match. Our rigorous research and testing, as outlined in our Asset Location methodology, demonstrates that accounts managed by Tax Coordination are expected to yield meaningfully higher after-tax returns than uncoordinated accounts. How to benefit from Betterment’s Tax Coordination To benefit from from our Tax Coordination feature, you first need to be a Betterment customer with a balance in at least two of the following types of Betterment accounts: Taxable account Tax-deferred account: A Traditional IRA or a Betterment Traditional 401(k) offered by your employer. Tax-exempt account: A Roth IRA or a Betterment Roth 401(k) offered by your employer. Note that you can only include a 401(k) in a goal using Tax Coordination if it’s one we manage on behalf of your current or former employer. If your employer doesn’t currently use Betterment to provide their 401(k) plan, tell them to give us a look at betterment.com/work! If you have an old 401(k) with a previous employer, you can still benefit from our Tax Coordination feature by rolling it over to a Betterment IRA.

Can a portfolio be too simple? Total market funds offer simplicity, but by unbundling asset classes—and adding Betterment’s automation—you can make your money work harder. Key takeaways Single-fund portfolios are easy to build, but they’re harder to optimize for taxes and costs. Using multiple funds adds the flexibility to fine-tune allocations and unlock savings. Betterment’s automation and expert-built portfolios give you the best of both worlds: easy to invest in, and built to work harder. If you’re looking to build long-term wealth, you could do worse than investing in one or two low-cost, globally-diversified total market funds. But you could potentially do better—and spend less of your limited bandwidth—by using a few more pieces and putting our technology to work in your favor. That’s the value of Betterment’s automated investing and expert-built portfolios, and it begins with (surprise!) tax optimization. Harvesting losses for tax wins, and putting your assets in the right place Targeting more than a date Splitting hairs on fund fees, so customers can save millions Harvesting losses for tax wins, and putting your assets in the right place Tax-loss harvesting can help give your taxable investing an edge, and it happens when we sell and replace similar assets using available funds. The downside of a total market fund, however, is you have to wait for the entire fund to experience a loss. If only one piece of it dips, you can’t unbundle the assets and harvest that specific piece. It’s sell all, or sell nothing. That’s a big reason why we switched from using a single fund for U.S. stocks in our Betterment-built portfolios, opting instead for three separate funds representing small, medium, and large-sized U.S. companies. If one of them presents a harvesting opportunity, we can swap it for a similar alternative. The second area where larger fund lineups shine is asset location, or strategically divvying up your portfolio’s assets among traditional, Roth, and/or taxable accounts. Stocks with the highest potential for growth, for example, are often better-suited for traditional accounts. Let them grow tax-free, the thinking goes, then settle up with Uncle Sam when you’re retired and more likely to be in a lower tax bracket. Our mathematically-rigorous spin on asset location is called Tax Coordination, and it’s yet another way our automated investing helps you keep more of what you earn. To start taking advantage of it, simply open any combination of the three account types above and follow a few easy steps. Targeting more than a date One of the most common single-fund options for retirement savings are target date funds. They date back to the 90s and became the default option in many 401(k) plans starting in the late 2000s. The growth of target date funds has been a good thing for investors, helping move the industry toward lower-cost, automated investing. Prior to their arrival, advisors had to manually adjust the asset allocations or “glide paths” of portfolios over time. Similar to total market funds, however, the bundling of target date funds brings with it some constraints. The first constraint is their relative lack of choice. Say you were born in 1988 and are targeting a traditional retirement age of 62. Most target date fund managers give you one option—the 2050 fund. Our automated investing, on the other hand, gives you more than a handful of portfolios to choose from, including ones tailored for social responsibility and innovation. More funds also creates more levers to fine-tune your exposure, helping manage risk in all sorts of situations. Take bond-heavy portfolios as an example. Rising interest rates can erode their value, so we dial up their exposure to short-term corporate debt and U.S. Treasuries specifically to help hedge against that risk. Splitting hairs on fund fees, so customers can save millions The relatively high cost of target date funds has been trending downward, and many total market funds can be found for expense ratios of less than 0.1%. But we can squeeze out even more savings by splitting a portfolio up and shopping for better deals. A single one hundredth of a percentage point in fund fees (what’s referred to as a “basis point” or “bip” in investing lingo) may not sound like much, but we owe it to our customers to make every one count. You could pay 6 basis points (0.06%), for example, for a total world stock fund like VT. Or you could pay one-third of that for your U.S. stock allocation by breaking it up into three funds (SPYM, SPMD, and SPSM) like we do with our Core portfolio and others. Using our customers’ nearly $20 billion worth of U.S. stocks as an example, that would amount to roughly $7.6 million in combined savings each year. Flexibility to stretch your investing dollars even farther A simple portfolio can be a great place to start, but it’s not always where your money works hardest. By strategically using a few more funds, we can sprinkle tax advantages on more of your investing, optimize across account types, and potentially unlock even more cost savings. All automatically. You get the simplicity you want, but with our tech doing the heavy lifting behind the scenes.

Betterment's asset location methodology
Betterment's asset location methodology Jun 23, 2026 12:00:00 AM Intelligently applying asset location to a globally diversified portfolio is a complex, mathematically rigorous, and continuous undertaking. TABLE OF CONTENTS Summary Part I: Introduction to Asset Location Part II: After-Tax Return—Deep Dive Part III: Asset Location Myths Part IV: TCP Methodology Part V: Monte Carlo on the Amazon—Betterment’s Testing Framework Part VI: Results Part VII: Special Considerations Addendum Summary Asset location is widely regarded as the closest thing there is to a "free lunch" in the wealth management industry.1 When investments are held in at least two types of accounts (out of three possible types: taxable, tax-deferred and tax-exempt), asset location provides the ability to deliver additional after-tax return potential, while maintaining the same level of risk. Generally speaking, this benefit is achieved by placing the least tax-efficient assets in the accounts taxed most favorably, and the most tax-efficient assets in the accounts taxed least favorably, all while maintaining the desired asset allocation in the aggregate. Part I: Introduction to Asset Location Maximizing after-tax return on investments can be complex. Still, most investors know that contributing to tax-advantaged (or "qualified") accounts is a relatively straightforward way to pay less tax on their retirement savings. Millions of Americans wind up with some combination of IRAs and 401(k) accounts, both available in two types: traditional or Roth. Many will only save in a taxable account once they have maxed out their contribution limits for the qualified accounts. But while tax considerations are paramount when choosing which account to fund, less thought is given to the tax impact of which investments to then purchase across all accounts. The tax profiles of the three account types (taxable, traditional, and Roth) have implications for what to invest in, once the account has been funded. Choosing wisely can significantly improve the after-tax value of one’s savings, when more than one account is in the mix. Almost universally, such investors can benefit from a properly executed asset location strategy. The idea behind asset location is fairly straightforward. Certain investments generate their returns in a more tax-efficient manner than others. Certain accounts shelter investment returns from tax better than others. Placing, or "locating" less tax-efficient investments in tax-sheltered accounts could increase the after-tax value of the overall portfolio. Allocate First, Locate Second Let’s start with what asset location isn’t. All investors must select a mix of stocks and bonds, finding an appropriate balance of risk and expected potential return, in line with their goals. One common goal is retirement, in which case, the mix of assets should be tailored to match the investor’s time horizon. This initial determination is known as "asset allocation," and it comes first. When investing in multiple accounts, it is common for investors to simply recreate their desired asset allocation in each account. If each account, no matter the size, holds the same assets in the same proportions, adding up all the holdings will also match the desired asset allocation. If all these funds, however scattered, are invested towards the same goal, this is the right result. The aggregate portfolio is the one that matters, and it should track the asset allocation selected for the common goal. Portfolio Managed Separately in Each Account Enter asset location, which can only be applied once a desired asset allocation is selected. Each asset’s after-tax return is considered in the context of every available account. The assets are then arranged (unequally) across all coordinated accounts to help maximize the after-tax performance of the overall portfolio. Same Portfolio Overall—With Asset Location To help conceptualize asset location, consider a team of runners. Some runners compete better on a track than a cross-country dirt path, as compared to their more versatile teammates. Similarly, certain asset classes can benefit more than others from the tax-efficient "terrain" of a qualified account. Asset allocation determines the composition of the team, and the overall portfolio’s after-tax return is a team effort. Asset location then seeks to match up asset and environment in a way that maximizes the overall result over time, while keeping the composition of the team intact. TCP vs. TDF The primary appeal of a target-date fund (TDF) is the "set it and forget it" simplicity with which it allows investors to select and maintain a diversified asset allocation, by purchasing only one fund. That simplicity comes at a price—because each TDF is a single, indivisible security, it cannot unevenly distribute its underlying assets across multiple accounts, and thus cannot deliver the additional after-tax returns of asset location. In particular, participants who are locked into 401(k) plans without automated management may find that a cheap TDF is still their best "hands off" option (plus, a TDF’s ability to satisfy the Qualified Default Investment Alternative (QDIA) requirement under ERISA ensures its baseline survival under current law). Participants in a Betterment at Work plan can already enable Betterment’s Tax-Coordinated Portfolio feature (“TCP”) to manage a single portfolio across their 401(k), IRAs and taxable accounts they individually have with Betterment, designed to squeeze additional after-tax returns from their aggregate long-term savings. Automated asset location (when integrated with automated asset allocation) replicates what makes a TDF so appealing, but effectively amounts to a "TDF 2.0"—a continuously managed portfolio, but one that can straddle multiple accounts for tax benefits. Next, we dive into the complex dynamics that need to be considered when seeking to optimize the after-tax return of a diversified portfolio. Part II: After-Tax Return—Deep Dive A good starting point for a discussion of investment taxation is the concept of "tax drag." Tax drag is the portion of the return that is lost to tax on an annual basis. In particular, funds pay dividends, which are taxed in the year they are received. However, there is no annual tax in qualified accounts, also sometimes known as "tax-sheltered accounts." Therefore, placing assets that pay a substantial amount of dividends into a qualified account, rather than a taxable account, "shelters" those dividends, and reduces tax drag. Reducing the tax drag of the overall portfolio is one way that asset location improves the portfolio’s potential after-tax return. Importantly, investments are also subject to tax at liquidation, both in the taxable account, and in a traditional IRA (where tax is deferred). However, "tax drag", as that term is commonly used, does not include liquidation tax. So while the concept of "tax drag" is intuitive, and thus a good place to start, it cannot be the sole focus when looking to help minimize taxes. What is "Tax Efficiency" A closely related term is "tax efficiency" and this is one that most discussions of asset location will inevitably focus on. A tax-efficient asset is one that has minimal "tax drag." Prioritizing assets on the basis of tax efficiency allows for asset location decisions to be made following a simple, rule-based approach. Both "tax drag" and "tax efficiency" are concepts pertaining to taxation of returns in a taxable account. Therefore, we first consider that account, where the rules are most elaborate. With an understanding of these rules, we can layer on the impact of the two types of qualified accounts. Returns in a Taxable Account There are two types of investment income, and two types of applicable tax rates. Two types of investment tax rates. All investment income in a taxable brokerage account is subject to one of two rate categories (with material exceptions noted). For simplicity, and to keep the analysis universal, this section only addresses federal tax (state tax is considered when testing for performance). Ordinary rate: For most, this rate mirrors the marginal tax bracket applicable to earned income (primarily wages reported on a W-2). Preferential rate: This more favorable rate ranges from 15% to 20% for most investors. For especially high earners, both rates are subject to an additional tax of 3.8%. Two types of investment returns. Investments generate returns in two ways: by appreciating in value, and by making cash distributions. Capital gains: When an investment is sold, the difference between the proceeds and the tax basis (generally, the purchase price) is taxed as capital gains. If held for longer than a year, this gain is treated as long-term capital gains (LTCG) and taxed at the preferential rate. If held for a year or less, the gain is treated as short-term capital gains (STCG), and taxed at the ordinary rate. Barring unforeseen circumstances, passive investors should be able to avoid STCG entirely. Betterment’s automated account management seeks to avoid STCG when possible,4 and the rest of this paper assumes only LTCG on liquidation of assets. Dividends: Bonds pay interest, which is taxed at the ordinary rate, whereas stocks pay dividends, which are taxed at the preferential rate (both subject to the exceptions below). An exchange-traded fund (ETF) pools the cash generated by its underlying investments, and makes payments that are called dividends, even if some or all of the source was interest. These dividends inherit the tax treatment of the source payments. This means that, generally, a dividend paid by a bond ETF is taxed at the ordinary rate, and a dividend paid by a stock ETF is taxed at the preferential rate. Qualified Dividend Income (QDI): There is an exception to the general rule for stock dividends. Stock dividends enjoy preferential rates only if they meet the requirements of qualified dividend income (QDI). Key among those requirements is that the company issuing the dividend must be a U.S. corporation (or a qualified foreign corporation). A fund pools dividends from many companies, only some of which may qualify for QDI. To account for this, the fund assigns itself a QDI percentage each year, which the custodian uses to determine the portion of the fund’s dividends that are eligible for the preferential rate. For stock funds tracking a U.S. index, the QDI percentage is typically 100%. However, funds tracking a foreign stock index will have a lower QDI percentage, sometimes substantially. For example, VWO, Vanguard’s Emerging Markets Stock ETF, had a QDI percentage of 38% in 2015, which means that 38% of its dividends for the year were taxed at the preferential rate, and 62% were taxed at the ordinary rate. Tax-exempt interest: There is also an exception to the general rule for bonds. Certain bonds pay interest that is exempt from federal tax. Primarily, these are municipal bonds, issued by state and local governments. This means that an ETF which holds municipal bonds will pay a dividend that is subject to 0% federal tax—even better than the preferential rate. The table below summarizes these interactions. Note that this section does not consider tax treatment for those in a marginal tax bracket of 15% and below. These taxpayers are addressed in "Special Considerations." Dividends (taxed annually) Capital Gains (taxed when sold) Ordinary Rate Most bonds Non-QDI stocks (foreign) Any security held for a year or less (STCG) Preferential Rate QDI stocks (domestic and some foreign) Any security held for more than a year (LTCG) No Tax Municipal bonds Any security transferred upon death or donated to charity The impact of rates is obvious: The higher the rate, the higher the tax drag. Equally important is timing. The key difference between dividends and capital gains is that the former are taxed annually, contributing to tax drag, whereas tax on the latter is deferred. Tax deferral is a powerful driver of after-tax return, for the simple reason that the savings, though temporary, can be reinvested in the meantime, and compounded. The longer the deferral, the more valuable it is. Putting this all together, we arrive at the foundational piece of conventional wisdom, where the most basic approach to asset location begins and ends: Bond funds are expected to generate their return entirely through dividends, taxed at the ordinary rate. This return benefits neither from the preferential rate, nor from tax deferral, making bonds the classic tax-inefficient asset class. These go in your qualified account. Stock funds are expected to generate their return primarily through capital gains. This return benefits both from the preferential rate, and from tax deferral. Stocks are therefore the more tax-efficient asset class. These go in your taxable account. Tax-Efficient Status: It’s Complicated Reality gets messy rather quickly, however. Over the long term, stocks are expected to grow faster than bonds, causing the portfolio to drift from the desired asset allocation. Rebalancing may periodically realize some capital gains, so we cannot expect full tax deferral on these returns (although if cash flows exist, investing them intelligently can potentially reduce the need to rebalance via selling). Furthermore, stocks do generate some return via dividends. The expected dividend yield varies with more granularity. Small cap stocks pay relatively little (these are growth companies that tend to reinvest any profits back into the business) whereas large cap stocks pay more (as these are mature companies that tend to distribute profits). Depending on the interest rate environment, stock dividends can exceed those paid by bonds. International stocks pay dividends too, and complicating things further, some of those dividends will not qualify as QDI, and will be taxed at the ordinary rate, like bond dividends (especially emerging markets stock dividends). Returns in a Tax-Deferred Account (TDA) Compared to a taxable account, a TDA is governed by straightforward rules. However, earning the same return in a TDA involves trade-offs which are not intuitive. Applying a different time horizon to the same asset can swing our preference between a taxable account and a TDA.Understanding these dynamics is crucial to appreciating why an optimal asset location methodology cannot ignore liquidation tax, time horizon, and the actual composition of each asset’s expected return.Although growth in a traditional IRA or traditional 401(k) is not taxed annually, it is subject to a liquidation tax. All the complexity of a taxable account described above is reduced to two rules. First, all tax is deferred until distributions are made from the account, which should begin only in retirement. Second, all distributions are taxed at the same rate, no matter the source of the return. The rate applied to all distributions is the higher ordinary rate, except that the additional 3.8% tax will not apply to those whose tax bracket in retirement would otherwise be high enough.2 First, we consider income that would be taxed annually at the ordinary rate (i.e. bond dividends and non-QDI stock dividends). The benefit of shifting these returns to a TDA is clear. In a TDA, these returns will eventually be taxed at the same rate, assuming the same tax bracket in retirement. But that tax will not be applied until the end, and compounding due to deferral can only have a positive impact on the after-tax return, as compared to the same income paid in a taxable account.3 In particular, the risk is that LTCG (which we expect plenty of from stock funds) will be taxed like ordinary income. Under the basic assumption that in a taxable account, capital gains tax is already deferred until liquidation, favoring a TDA for an asset whose only source of return is LTCG is plainly harmful. There is no benefit from deferral, which you would have gotten anyway, and only harm from a higher tax rate. This logic supports the conventional wisdom that stocks belong in the taxable account. First, as already discussed, stocks do generate some return via dividends, and that portion of the return will benefit from tax deferral. This is obviously true for non-QDI dividends, already taxed as ordinary income, but QDI can benefit too. If the deferral period is long enough, the value of compounding will offset the hit from the higher rate at liquidation. Second, it is not accurate to assume that all capital gains tax will be deferred until liquidation in a taxable account. Rebalancing may realize some capital gains "prematurely" and this portion of the return could also benefit from tax deferral. Placing stocks in a TDA is a trade-off—one that must weigh the potential harm from negative rate arbitrage against the benefit of tax deferral. Valuing the latter means making assumptions about dividend yield and turnover. On top of that, the longer the investment period, the more tax deferral is worth. Kitces demonstrates that a dividend yield representing 25% of total return (at 100% QDI), and an annual turnover of 10%, could swing the calculus in favor of holding the stocks in a TDA, assuming a 30-year horizon.4 For foreign stocks with less than perfect QDI, we would expect the tipping point to come sooner. Returns in a Tax-Exempt Account (TEA) Qualifying investments in a Roth IRA or Roth 401(k) grow tax free, and are also not taxed upon liquidation. Since it eliminates all possible tax, a TEA presents a particularly valuable opportunity for maximizing after-tax return. The trade-off here is managing opportunity cost—every asset does better in a TEA, so how best to use its precious capacity? Clearly, a TEA is the most favorably taxed account. Conventional wisdom thus suggests that if a TEA is available, we use it to first place the least tax-efficient assets. But that approach is wrong. Everything Counts in Large Amounts—Why Expected Return Matters The powerful yet simple advantage of a TEA helps illustrate the limitation of focusing exclusively on tax efficiency when making location choices. Returns in a TEA escape all tax, whatever the rate or timing would have been, which means that an asset’s expected after-tax return equals its expected total return. When both a taxable account and a TEA are available, it may be worth putting a high-growth, low-dividend stock fund into the TEA, instead of a bond fund, even though the stock fund is vastly more tax-efficient. Similar reasoning can apply to placement in a TDA as well, as long as the tax-efficient asset has a large enough expected return, and presents some opportunity for tax deferral (i.e., some portion of the return comes from dividends). Part III: Asset Location Myths Urban Legend 1: Asset location is a one-time process. Just set it and forget it. While an initial location may add some value, doing it properly is a continuous process, and will require adjustments in response to changing conditions. Note that overlaying asset location is not a deviation from a passive investing philosophy, because optimizing for location does not mean changing the overall asset allocation (the same goes for tax loss harvesting). Other things that will change, all of which should factor into an optimal methodology: expected returns (both the risk-free rate, and the excess return), dividend yields, QDI percentages, and most importantly, relative account balances. Contributions, rollovers, and conversions can increase qualified assets relative to taxable assets, continuously providing more room for additional optimization. Urban Legend 2: Taking advantage of asset location means you should contribute more to a particular qualified account than you otherwise would. Definitely not! Asset location should play no role in deciding which accounts to fund. It optimizes around account balances as it finds them, and is not concerned with which accounts should be funded in the first place. Just because the presence of a TEA makes asset location more valuable, does not mean you should contribute to a TEA, as opposed to a TDA. That decision is primarily a bet on how your tax rate today will compare to your tax rate in retirement. To hedge, some may find it optimal to make contributions to both a TDA and TEA (this is called "tax diversification"). While these decisions are out of scope for this paper, Betterment’s retirement planning tools can help clients with these choices. Urban Legend 3: Asset location has very little value if one of your accounts is relatively small. It depends. Asset location will not do much for investors with a very small taxable balance and a relatively large balance in only one type of qualified account, because most of the overall assets are already sheltered. However, a large taxable balance and a small qualified account balance (especially a TEA balance) presents a better opportunity. Under these circumstances, there may be room for only the least tax-efficient, highest-return assets in the qualified account. Sheltering a small portion of the overall portfolio can deliver a disproportionate amount of value. Urban Legend 4: Asset location has no value if you are investing in both types of qualified accounts, but not in a taxable account. A TEA offers significant advantages over a TDA. Zero tax is better than a tax deferred until liquidation. While tax efficiency (i.e. annual tax drag) plays no role in these location decisions, expected returns and liquidation tax do. The assets we expect to grow the most should be placed in a TEA, and doing so will plainly increase the overall after-tax return. There is an additional benefit as well. Required minimum distributions (RMDs) apply to TDAs but not TEAs. Shifting expected growth into the TEA, at the expense of the TDA, will mean lower RMDs, giving the investor more flexibility to control taxable income down the road. In other words, a lower balance in the TDA can mean lower tax rates in retirement, if higher RMDs would have pushed the retiree into a higher bracket. This potential benefit is not captured in our results. Urban Legend 5: Bonds always go in the IRA. Possibly, but not necessarily. This commonly asserted rule is a simplification, and will not be optimal under all circumstances. It is discussed at more length below. Existing Approaches to Asset Location: Advantages and Limitations Optimizing for After-Tax Return While Maintaining Separate Portfolios One approach to increasing after-tax return on retirement savings is to maintain a separate, standalone portfolio in each account with roughly the same level of risk-adjusted return, but tailoring each portfolio somewhat to take advantage of the tax profile of the account. Effectively, this means that each account separately maintains the desired exposure to stocks, while substituting certain asset classes for others. Generally speaking, managing a fully diversified portfolio in each account means that there is no way to avoid placing some assets with the highest expected return in the taxable account. This approach does include a valuable tactic, which is to differentiate the high-quality bonds component of the allocation, depending on the account they are held in. The allocation to the component is the same in each account, but in a taxable account, it is represented by municipal bonds which are exempt from federal tax , and in a qualified account, by taxable investment grade bonds . This variation is effective because it takes advantage of the fact that these two asset classes have very similar characteristics (expected returns, covariance and risk exposures) allowing them to play roughly the same role from an asset allocation perspective. Municipal bonds are highly tax-efficient due to their federal tax-exempt interest income, making them particularly compelling for a taxable account. Taxable investment grade bonds have significant tax drag, and work best in a qualified account. Betterment has applied this substitution since 2014. The Basic Priority List Gobind Daryanani and Chris Cordaro sought to balance considerations around tax efficiency and expected return, and illustrated that when both are very low, location decisions with respect to those assets have very limited impact.5 That study inspired Michael Kitces, who leverages its insights into a more sophisticated approach to building a priority list.6 To visually capture the relationship between the two considerations, Kitces bends the one-dimensional list into a "smile." Asset Location Priority List Assets with a high expected return that are also very tax-efficient go in the taxable account. Assets with a high expected return that are also very tax-inefficient go in the qualified accounts, starting with the TEA. The "smile" guides us in filling the accounts from both ends simultaneously, and by the time we get to the middle, whatever decisions we make with respect to those assets just "don’t matter" much. However, Kitces augments the graph in short order, recognizing that the basic "smile" does not capture a third key consideration—the impact of liquidation tax. Because capital gains will eventually be realized in a taxable account, but not in a TEA, even a highly tax-efficient asset might be better off in a TEA, if its expected return is high enough. The next iteration of the "smile" illustrates this preference. Asset Location Priority List with Limited High Return Inefficient Assets Part IV: TCP Methodology There is no one-size-fits-all asset location for every set of inputs. Some circumstances apply to all investors, but shift through time—the expected return of each asset class (which combines separate assumptions for the risk-free rate and the excess return), as well as dividend yields, QDI percentages, and tax laws. Other circumstances are personal—which accounts the client has, the relative balance of each account, and the client’s time horizon. Solving for multiple variables while respecting defined constraints is a problem that can be effectively solved by linear optimization. This method is used to maximize some value, which is represented by a formula called an "objective function." What we seek to maximize is the after-tax value of the overall portfolio at the end of the time horizon. We get this number by adding together the expected after-tax value of every asset in the portfolio, but because each asset can be held in more than one account, each portion must be considered separately, by applying the tax rules of that account. We must therefore derive an account-specific expected after-tax return for each asset. Deriving Account-Specific After-Tax Return To define the expected after-tax return of an asset, we first need its total return (i.e., before any tax is applied). The total return is the sum of the risk-free rate (same for every asset) and the excess return (unique to every asset). Betterment derives excess returns using the Black-Litterman model as a starting point. This common industry method involves analyzing the global portfolio of investable assets and their proportions, and using them to generate forward-looking expected returns for each asset class. Next, we must reduce each total return into an after-tax return.7 The immediate problem is that for each asset class, the after-tax return can be different, depending on the account, and for how long it is held. In a TEA, the answer is simple—the after-tax return equals the total return—no calculation necessary. In a TDA, we project growth of the asset by compounding the total return annually. At liquidation, we apply the ordinary rate to all of the growth.8 We use what is left of the growth after taxes to derive an annualized return, which is our after-tax return. In a taxable account, we need to consider the dividend and capital gain component of the total return separately, with respect to both rate and timing. We project growth of the asset by taxing the dividend component annually at the ordinary rate (or the preferential rate, to the extent that it qualifies as QDI) and adding back the after-tax dividend (i.e., we reinvest it). Capital gains are deferred, and the LTCG is fully taxed at the preferential rate at the end of the period. We then derive the annualized return based on the after-tax value of the asset.9 Note that for both the TDA and taxable calculations, time horizon matters. More time means more value from deferral, so the same total return can result in a higher annualized after-tax return. Additionally, the risk-free rate component of the total return will also depend on the time horizon, which affects all three accounts. Because we are accounting for the possibility of a TEA, as well, we actually have three distinct after-tax returns, and thus each asset effectively becomes three assets, for any given time horizon (which is specific to each Betterment customer). The Objective Function To see how this comes together, we first consider an extremely simplified example. Let’s assume we have a taxable account, both a traditional and Roth account, with $50,000 in each one, and a 30-year horizon. Our allocation calls for 70% equities (stocks), so with a total portfolio value of $150,000, we need $105,000 of stocks. 1. These are constants whose value we already know (as derived above). req,tax is the after-tax return of stocks in the taxable account, over 30 years req,trad is the after-tax return of stocks in the traditional account, over 30 years req,roth is the after-tax return of stocks in the Roth account, over 30 years rfi,tax is the after-tax return of bonds in the taxable account, over 30 years rfi,trad is the after-tax return of bonds in the traditional account, over 30 years rfi,roth is the after-tax return of bonds in the Roth account, over 30 years 2. These are the values we are trying to solve for (called "decision variables"). xeq,tax is the amount of stocks we will place in the taxable account xeq,trad is the amount of stocks we will place in the traditional account xeq,roth is the amount of stocks we will place in the Roth account xfi,tax is the amount of bonds we will place in the taxable account xfi,trad is the amount of bonds we will place in the traditional account xfi,roth is the amount of bonds we will place in the Roth account 3. These are the constraints which must be respected. All positions for each asset must add up to what we have allocated to the asset overall. All positions in each account must add up to the available balance in each account. xeq,tax + xeq,trad + xeq,roth = 105,000 xfi,tax + xfi,trad + xfi,roth = 45,000 xeq,tax + xfi,tax = 50,000 xeq,trad + xfi,trad = 50,000 xeq,roth + xfi,roth = 50,000 4. This is the objective function, which uses the constants and decision variables to express the after-tax value of the entire portfolio, represented by the sum of six terms (the after-tax value of each asset in each of the three accounts). maxx req,taxxeq,tax + req,tradxeq,trad + req,rothxeq,roth + rfi,taxxfi,tax + rfi,tradxfi,trad + rfi,rothxfi,roth Linear optimization turns all of the above into a complex geometric representation, and mathematically closes in on the optimal solution. It assigns values for all decision variables in a way that maximizes the value of the objective function, while respecting the constraints. Accordingly, each decision variable is a precise instruction for how much of which asset to put in each account. If a variable comes out as zero, then that particular account will contain none of that particular asset. An actual Betterment portfolio can potentially have twelve asset classes,15 depending on the allocation. That means TCP must effectively handle up to 36 "assets," each with its own after-tax return. However, the full complexity behind TCP goes well beyond increasing assets from two to twelve. Updated constants and constraints will trigger another part of the optimization, which determines what TCP is allowed to sell, in order to move an already coordinated portfolio toward the newly optimal asset location, while minimizing taxes. Reshuffling assets in a TDA or TEA is "free" in the sense that no capital gains will be realized.10 In the taxable account, however, TCP will attempt to move as close as possible towards the optimal asset location without realizing capital gains. Expected returns will periodically be updated, either because the risk-free rate has been adjusted, or because new excess returns have been derived via Black-Litterman. Future cash flows may be even more material. Additional funds in one or more of the accounts could significantly alter the constraints which define the size of each account, and the target dollar allocation to each asset class. Such events (including dividend payments, subject to a de minimis threshold) will trigger a recalculation, and potentially a reshuffling of the assets. Cash flows, in particular, can be a challenge for those managing their asset location manually. Inflows to just one account (or to multiple accounts in unequal proportions) create a tension between optimizing asset location and maintaining asset allocation, which is hard to resolve without mathematical precision. To maintain the overall asset allocation, each position in the portfolio must be increased pro-rata. However, some of the additional assets we need to buy "belong" in other accounts from an asset location perspective, even though new cash is not available in those accounts. If the taxable account can only be partially reshuffled due to built-in gains, we must choose either to move farther away from the target allocation, or the target location.11 With linear optimization, our preferences can be expressed through additional constraints, weaving these considerations into the overall problem. When solving for new cash flows, TCP penalizes allocation drift higher than it does location drift. Against this background, it is important to note that expected returns (the key input into TCP, and portfolio management generally) are educated guesses at best. No matter how airtight the math, reasonable people will disagree on the "correct" way to derive them, and the future may not cooperate, especially in the short-term. There is no guarantee that any particular asset location will add the most value, or even any value at all. But given decades, the likelihood of this outcome grows. For portfolios that include a cash allocation, Betterment locates the entire cash allocation in the taxable account within the Tax-Coordinated Portfolio first, consistent with our asset location approach of reserving tax-advantaged accounts for assets with higher expected returns. If the portfolio does not include a taxable account, cash will be located in a traditional IRA before a Roth IRA. Tax-Coordinated Portfolios that include a 401(k) will not include a cash allocation. Part V: Monte Carlo—Betterment’s Testing Framework To test the output of the linear optimization method, we turned to a Monte Carlo testing framework,12 built entirely in-house by Betterment’s experts. The forward-looking simulations model the behavior of the TCP strategy down to the individual lot level. We simulate the paths of these lots, accounting for dividend reinvestment, rebalancing, and taxation. The simulations applied Betterment’s rebalancing methodology, which corrects drift from the target asset allocation in excess of the applicable drift threshold once the account balances meet or exceed the required minimum, but stops short of realizing STCG, when possible. Betterment’s management fees were assessed in all accounts, and ongoing taxes were paid annually from the taxable account. All taxable sales first realized available losses before touching LTCG. The simulations assume no additional cash flows other than dividends. This is not because we do not expect them to happen. Rather, it is because making assumptions around these very personal circumstances does nothing to isolate the benefit of TCP specifically. Asset location is driven by the relative sizes of the accounts, and cash flows will change these ratios, but the timing and amount is highly specific to the individual.19 Avoiding the need to make specific assumptions here helps keep the analysis more universal. We used equal starting balances for the same reason.13 For every set of assumptions, we ran each market scenario while managing each account as a standalone (uncoordinated) Betterment portfolio as the benchmark.14 We then ran the same market scenarios with TCP enabled. In both cases, we calculated the after-tax value of the aggregate portfolio after full liquidation of invested assets at the end of the period.15 Then, for each market scenario, we calculated the after-tax annualized internal rates of return (IRR) and subtracted the benchmark IRR from the TCP IRR. That delta represents the incremental tax alpha of TCP for that scenario. The median of those deltas across all market scenarios is the estimated tax alpha we present below for each set of assumptions. Part VI: Results More Bonds, More Alpha A higher allocation to bonds leads to a dramatically higher benefit across the board. This makes sense—the heavier your allocation to tax-inefficient assets, the more asset location can do for you. To be extremely clear: this is not a reason to select a lower allocation to stocks! Over the long-term, we expect a higher stock allocation to return more (because it’s riskier), both before, and after tax. These are measurements of the additional return due to TCP, which say nothing about the absolute return of the asset allocation itself. Conversely, a very high allocation to stocks shows a smaller (though still real) benefit. However, younger customers invested this aggressively should gradually reduce risk as they get closer to retirement (to something more like 50% stocks). Looking to a 70% stock allocation is therefore an imperfect but reasonable way to generalize the value of the strategy over a 30-year period. More Roth, More Alpha Another pattern is that the presence of a Roth makes the strategy more valuable. This also makes sense—a taxable account and a TEA are on opposite ends of the "favorably taxed" spectrum, and having both presents the biggest opportunity for TCP’s "account arbitrage." But again, this benefit should not be interpreted as a reason to contribute to a TEA over a TDA, or to shift the balance between the two via a Roth conversion. These decisions are driven by other considerations. TCP’s job is to optimize the relative balances as it finds them. Enabling TCP On Existing Taxable Accounts TCP should be enabled before the taxable account is funded, meaning that the initial location can be optimized without the need to sell potentially appreciated assets. A Betterment customer with an existing taxable account who enables TCP should not expect the full incremental benefit, to the extent that assets with built-in capital gains need to be sold to achieve the optimal location. This is because TCP conservatively prioritizes avoiding a certain tax today, over potentially reducing tax in the future. However, the optimization is performed every time there is a deposit (or dividend) to any account. With future cash flows, the portfolio will move closer to whatever the optimal location is determined to be at the time of the deposit. Part VII: Special Considerations Low Bracket Taxpayers: Beware Taxation of investment income is substantially different for those who qualify for a marginal tax bracket of 15% or below. To illustrate, we have modified the chart from Part II to apply to such low bracket taxpayers. Dividends Capital Gains Ordinary Rate N/A Any security held for a year or less (STCG) Preferential Rate N/A N/A No Tax Qualified dividends from any security are not taxed Any security held for a year or more is not taxed (LTCG) TCP is not designed for these investors. Optimizing around this tax profile would reverse many assumptions behind TCP’s methodology. Municipal bonds no longer have an advantage over other bond funds. The arbitrage opportunity between the ordinary and preferential rate is gone. In fact, there’s barely tax of any kind. It is quite likely that such investors would not benefit much from TCP, and may even reduce their overall after-tax return. If the low tax bracket is temporary, TCP over the long-term may still make sense. Also note that some combinations of account balances can, in certain circumstances, still add tax alpha for investors in low tax brackets. One example is when an investor only has traditional and Roth IRA accounts, and no taxable accounts being tax coordinated. Low bracket investors should very carefully consider whether TCP is suitable for them. As a general rule, we do not recommend it. Potential Problems with Coordinating Accounts Meant for Different Time Horizons We began with the premise that asset location is sensible only with respect to accounts that are generally intended for the same purpose. This is crucial, because unevenly distributing assets will result in asset allocations in each account that are not tailored towards the overall goal (or any goal at all). This is fine, as long as we expect that all coordinated accounts will be available for withdrawals at roughly the same time (e.g. at retirement). Only the aggregate portfolio matters in getting there. However, uneven distributions are less diversified. Temporary drawdowns (e.g., the 2008 financial crisis) can mean that a single account may drop substantially more than the overall coordinated portfolio. If that account is intended for a short-term goal, it may not have a chance to recover by the time you need the money. Likewise, if you do not plan on depleting an account during your retirement, and instead plan on leaving it to be inherited for future generations, arguably this account has a longer time horizon than the others and should thus be invested more aggressively. In either case, we do not recommend managing accounts with materially different time horizons as a single portfolio. For a similar reason, you should avoid applying asset location to an account that you expect will be long-term, but one that you may look to for emergency withdrawals. For example, a Safety Net Goal should never be managed by TCP. Large Upcoming Transfers/Withdrawals If you know you will be making large transfers in or out of your tax-coordinated accounts, you may want to delay enabling our tax coordination tool until after those transfers have occurred. This is because large changes in the balances of the underlying accounts can necessitate rebalancing, and thus may cause taxes. With incoming deposits, we can intelligently rebalance your accounts by increasing the allocation of asset classes that are underweight. But when large withdrawals or transfers out are made, despite Betterment’s intelligent management of executing trades, some taxes can be unavoidable when rebalancing to your overall target allocation. The only exception to this rule is if the large deposit will be in your taxable account instead of your IRAs. In that case, you should enable tax-coordination before depositing money into the taxable account. This is so our system knows to tax-coordinate you immediately. The goal of tax coordination is to reduce the drag taxes have on your investments, not cause additional taxes. So if you know an upcoming withdrawal or outbound transfer could cause rebalancing, and thus taxes, it would be prudent to delay enabling tax coordination until you have completed those transfers. Mitigating Behavioral Challenges Through Design There is a broader issue that stems from locating assets with different volatility profiles at the account level, but it is behavioral. Uncoordinated portfolios with the same allocation move together. Asset location, on the other hand, will cause one account to dip more than another, testing an investor’s stomach for volatility. Those who enable TCP across their accounts should be prepared for such differentiated movements. Rationally, we should ignore this—after all, the overall allocation is the same—but that is easier said than done. How TCP Interacts with Tax Loss Harvesting TCP and TLH work in tandem, seeking to minimize tax impact. As described in more detail below, the precise interaction between the two strategies is highly dependent on personal circumstances. While it is possible that enabling a TCP may reduce harvest opportunities, both TLH and TCP derive their benefit without disturbing the desired asset allocation. Operational Interaction TLH was designed around a "tertiary ticker" system, which ensures that no purchase in an IRA or 401(k) managed by Betterment will interfere with a harvested loss in a Betterment taxable account. A sale in a taxable account, and a subsequent repurchase of the same asset class in a qualified account would be incidental for accounts managed as separate portfolios. Under TCP, however, we expect this to occasionally happen by design. When "relocating" assets, either during initial setup, or as part of ongoing optimization, TCP will sell an asset class in one account, and immediately repurchase it in another. The tertiary ticker system allows this reshuffling to happen seamlessly, while attempting to protect any tax losses that are realized in the process. Conceptualizing Blended Performance TCP will affect the composition of the taxable account in ways that are hard to predict, because its decisions will be driven by changes in relative balances among the accounts. Meanwhile, the weight of specific asset classes in the taxable account is a material predictor of the potential value of TLH (more volatile assets should offer more harvesting opportunities). The precise interaction between the two strategies is far more dependent on personal circumstances, such as today’s account balance ratios and future cash flow patterns, than on generally applicable inputs like asset class return profiles and tax rules. These dynamics are best understood as a hierarchy. Asset allocation comes first, and determines what mix of asset classes we should stick to overall. Asset location comes second, and continuously generates tax alpha across all coordinated accounts, within the constraints of the overall portfolio. Tax loss harvesting comes third, and looks for opportunities to generate tax alpha from the taxable account only, within the constraints of the asset mix dictated by asset location for that account. TLH is usually most effective in the first several years after an initial deposit to a taxable account. Over decades, however, we expect it to generate value only from subsequent deposits and dividend reinvestments. Eventually, even a substantial dip is unlikely to bring the market price below the purchase price of the older tax lots. Meanwhile, TCP aims to deliver tax alpha over the entire balance of all three accounts for the entire holding period. *** Betterment does not represent in any manner that TCP will result in any particular tax consequence or that specific benefits will be obtained for any individual investor. The TCP service is not intended as tax advice. Please consult your personal tax advisor with any questions as to whether TCP is a suitable strategy for you in light of your individual tax circumstances. Please see our Tax-Coordinated Portfolio Disclosures for more information. Addendum As of May 2020, for customers who indicate that they’re planning on using a Health Savings Account (HSA) for long-term savings, we allow the inclusion of their HSA in their Tax-Coordinated Portfolio. If an HSA is included in a Tax-Coordinated Portfolio, we treat it essentially the same as an additional Roth account. This is because funds within an HSA grow income tax-free, and withdrawals can be made income tax-free for medical purposes. With this assumption, we also implicitly assume that the HSA will be fully used to cover long-term medical care spending. The tax alpha numbers presented above have not been updated to reflect the inclusion of HSAs, but remain our best-effort point-in-time estimate of the value of TCP at the launch of the feature. As the inclusion of HSAs allows even further tax-advantaged contributions, we contend that the inclusion of HSAs is most likely to additionally benefit customers who enable TCP. 1"Boost Your After-Tax Investment Returns." Susan B. Garland. Kiplinger.com, April 2014. 2But see "How IRA Withdrawals In The Crossover Zone Can Trigger The 3.8% Medicare Surtax," Michael Kitces, July 23, 2014. 3It is worth emphasizing that asset location optimizes around account balances as it finds them, and has nothing to say about which account to fund in the first place. Asset location considers which account is best for holding a specified dollar amount of a particular asset. However, contributions to a TDA are tax-deductible, whereas getting a dollar into a taxable account requires more than a dollar of income. 4Pg. 5, The Kitces Report. January/February 2014. 5Daryanani, Gobind, and Chris Cordaro. 2005. "Asset Location: A Generic Framework for Maximizing After-Tax Wealth." Journal of Financial Planning (18) 1: 44–54. 6The Kitces Report, March/April 2014. 7While the significance of ordinary versus preferential tax treatment of income has been made clear, the impact of an individual’s specific tax bracket has not yet been addressed. Does it matter which ordinary rate, and which preferential rate is applicable, when locating assets? After all, calculating the after-tax return of each asset means applying a specific rate. It is certainly true that different rates should result in different after-tax returns. However, we found that while the specific rate used to derive the after-tax return can and does affect the level of resulting returns for different asset classes, it makes a negligible difference on resulting location decisions. The one exception is when considering using very low rates as inputs (the implication of which is discussed under "Special Considerations"). This should feel intuitive: Because the optimization is driven primarily by the relative size of the after-tax returns of different asset classes, moving between brackets moves all rates in the same direction, generally maintaining these relationships monotonically. The specific rates do matter a lot when it comes to estimating the benefit of the asset location chosen, so rate assumptions are laid out in the "Results" section. In other words, if one taxpayer is in a moderate tax bracket, and another in a high bracket, their optimal asset location will be very similar and often identical, but the high bracket investor may benefit more from the same location. 8In reality, the ordinary rate is applied to the entire value of the TDA, both the principal (i.e., the deductible contributions) and the growth. However, this will happen to the principal whether we use asset location or not. Therefore, we are measuring here only that which we can optimize. 9TCP today does not account for the potential benefit of a foreign tax credit (FTC). The FTC is intended to mitigate the potential for double taxation with respect to income that has already been taxed in a foreign country. The scope of the benefit is hard to quantify and its applicability depends on personal circumstances. All else being equal, we would expect that incorporating the FTC may somewhat increase the after-tax return of certain asset classes in a taxable account—in particular developed and emerging markets stocks. If maximizing your available FTC is important to your tax planning, you should carefully consider whether TCP is the optimal strategy for you. 10Standard market bid-ask spread costs will still apply. These are relatively low, as Betterment considers liquidity as a factor in its investment selection process. Betterment customers do not pay for trades. 11Additionally, in the interest of making interaction with the tool maximally responsive, certain computationally demanding aspects of the methodology were simplified for purposes of the tool only. This could result in a deviation from the target asset location imposed by the TCP service in an actual Betterment account. 12Another way to test performance is with a backtest on actual market data. One advantage of this approach is that it tests the strategy on what actually happened. Conversely, a forward projection allows us to test thousands of scenarios instead of one, and the future is unlikely to look like the past. Another limitation of a backtest in this context—sufficiently granular data for the entire Betterment portfolio is only available for the last 15 years. Because asset location is fundamentally a long-term strategy, we felt it was important to test it over 30 years, which was only possible with Monte Carlo. Additionally, Monte Carlo actually allows us to test tweaks to the algorithm with some confidence, whereas adjusting the algorithm based on how it would have performed in the past is effectively a type of "data snooping". 13That said, the strategy is expected to change the relative balances dramatically over the course of the period, due to unequal allocations. We expect a Roth balance in particular to eventually outpace the others, since the optimization will favor assets with the highest expected return for the TEA. This is exactly what we want to happen. 14For the uncoordinated taxable portfolio, we assume an allocation to municipal bonds (MUB) for the high-quality bonds component, but use investment grade taxable bonds (AGG) in the uncoordinated portfolio for the qualified accounts. While TCP makes use of this substitution, Betterment has offered it since 2014, and we want to isolate the additional tax alpha of TCP specifically, without conflating the benefits. 15Full liquidation of a taxable or TDA portfolio that has been growing for 30 years will realize income that is guaranteed to push the taxpayer into a higher tax bracket. We assume this does not happen, because in reality, a taxpayer in retirement will make withdrawals gradually. The strategies around timing and sequencing decumulation from multiple account types in a tax-efficient manner are out of scope for this paper. Additional References Berkin. A.

Betterment's tax-loss harvesting methodology
Betterment's tax-loss harvesting methodology Jun 18, 2026 12:00:00 AM Tax-loss harvesting is a sophisticated technique to get more value from your investments—but doing it well requires expertise. TABLE OF CONTENTS Navigating the “Wash Sale” rule The Betterment solution Tax-loss harvesting model calibration Best practices for TLH How we calculate the value of tax-loss harvesting Your personalized Estimated Tax Savings tool Conclusion There are many ways to get your investments to work harder for you— diversification, downside risk management, and an appropriate mix of asset classes tailored to your recommended allocation. Betterment does this automatically via its ETF portfolios. But there is another way to help you get more out of your portfolio—using investment losses to improve your after-tax returns with a method called tax-loss harvesting. In this article, we introduce Betterment’s tax-loss harvesting (TLH): a sophisticated, fully automated tool that Betterment customers can choose to enable. Betterment’s tax-loss harvesting service scans portfolios regularly for opportunities (temporary dips that result from market volatility) to realize losses which can be valuable come tax time. While the concept of tax-loss harvesting is not new for wealthy investors, tax-loss harvesting utilizes a number of innovations that typical implementations may lack. It takes a holistic approach to tax-efficiency, seeking to optimize user-initiated transactions in addition to adding value through automated activity, such as rebalances. What is tax-loss harvesting? Capital losses can lower your tax bill by offsetting gains, but the only way to realize a loss is to sell the depreciated asset. However, in a well-allocated portfolio, each asset plays an essential role in providing a piece of total market exposure. For that reason, an investor should not want to give up potential expected returns associated with each asset just to realize a loss. At its most basic level, tax-loss harvesting is selling a security that has experienced a loss—and then buying a correlated asset (i.e. one that provides similar exposure) to replace it. The strategy has two benefits: it allows the investor to “harvest” a valuable loss, and it keeps the portfolio balanced at the desired allocation. How can it lower your tax bill? Capital losses can be used to offset capital gains you’ve realized in other transactions over the course of a year—gains on which you would otherwise owe tax. Then, if there are losses left over (or if there were no gains to offset), you can offset up to $3,000 of ordinary income for the year. If any losses still remain, they can be carried forward indefinitely. Tax-loss harvesting is primarily a tax deferral strategy, and its benefit depends entirely on individual circumstances. Over the long run, it can add value through some combination of these distinct benefits that it seeks to provide: Tax deferral: Losses harvested can be used to offset unavoidable gains in the portfolio, or capital gains elsewhere (e.g., from selling real estate), deferring the tax owed. Savings that are invested may grow, assuming a conservative growth rate of 5% over a 10-year period, a dollar of tax deferred would be worth $1.63. Even after belatedly parting with the dollar, and paying tax on the $0.63 of growth, you’re ahead. Pushing capital gains into a lower tax rate: If you’ve realized short-term capital gains (STCG) this year, they’ll generally be taxed at your highest rate. However, if you’ve harvested losses to offset them, the corresponding gain you owe in the future could be long-term capital gain (LTCG). You’ve effectively turned a gain that would have been taxed up to 50% today into a gain that will be taxed more lightly in the future (up to 30%). Converting ordinary income into long-term capital gains: A variation on the above: offsetting up to $3,000 from your ordinary income shields that amount from your top marginal rate, but the offsetting future gain will likely be taxed at the LTCG rate. Permanent tax avoidance in certain circumstances: Tax-loss harvesting provides benefits now in exchange for increasing built-in gains, subject to tax later. However, under certain circumstances (charitable donation, bequest to heirs), these gains may avoid taxation entirely. Navigating the "Wash Sale" rule Summary: Wash sale rule management is at the core of any tax-loss harvesting strategy. Unsophisticated approaches can detract from the value of the harvest or place constraints on customer cash flows in order to function. At a high level, the so-called "Wash Sale” rule disallows a loss from selling a security if a “substantially identical” security is purchased 30 days after or before the sale. The rationale is that a taxpayer should not enjoy the benefit of deducting a loss if they did not truly dispose of the security. The wash sale rule applies not just to situations when a “substantially identical” purchase is made in the same account, but also when the purchase is made in the individual’s IRA/401(k) account, or even in a spouse’s account. This broad application of the wash sale rule seeks to ensure that investors cannot utilize nominally different accounts to maintain their ownership, and still benefit from the loss. A wash sale involving an IRA/401(k) account is particularly unfavorable. Generally, a “washed” loss is postponed until the replacement is sold, but if the replacement is purchased in an IRA/401(k) account, the loss is permanently disallowed. If not managed correctly, wash sales can undermine tax-loss harvesting. Handling proceeds from the harvest is not the sole concern—any deposits made in the following 30 days (whether into the same account, or into the individual’s IRA/401(k)) also need to be allocated with care. Minimizing the wash The simplest way to avoid triggering a wash sale is to avoid purchasing any security at all for the 30 days following the harvest, keeping the proceeds (and any inflows during that period) in cash. This approach, however, would systematically keep a portion of the portfolio out of the market. More advanced strategies primarily repurchase an asset with similar exposure to the harvested security that is not “substantially identical” for purposes of the wash sale rule. In the case of an individual stock, it is clear that repurchasing stock of that same company would violate the rule. Less clear is the treatment of two index funds from different issuers (e.g., Vanguard and Schwab) that track the same index. While the IRS has not issued any guidance to suggest that such two funds are “substantially identical,” a more conservative approach when dealing with an index fund portfolio would be to repurchase a fund whose performance correlates closely with that of the harvested fund, but tracks a different index. Tax-loss harvesting is generally designed around this index-based logic and generally seeks to reduce wash sales, although it cannot avoid potential wash sales arising from transactions in tickers that track the same index where one of the tickers is not currently a primary, secondary, or tertiary ticker (as those terms are defined in this white paper). This situation could arise, for example, when other tickers are transferred to Betterment or where they were previously a primary, secondary, or tertiary ticker. Additionally, for some portfolios constructed by third parties (e.g., Vanguard, Blackrock, or Goldman Sachs), certain secondary and tertiary tickers track the same index. Certain asset classes (including those in certain Betterment-constructed portfolios and portfolios constructed by third parties, such as Vanguard, Blackrock, or Goldman Sachs) do not have tertiary tickers, such that permanently disallowed losses could occur if there were overlapping holdings in taxable and tax-advantaged accounts. Betterment’s TLH feature may also permit wash sales where the anticipated tax benefit of the overall harvest transaction sufficiently outweighs the impact of expected washed losses. Selecting a viable replacement security is just one piece of the accounting and optimization puzzle. Manually implementing a tax-loss harvesting strategy is feasible with a handful of securities, little to no cash flows, and infrequent harvests. Assets may however dip in value but potentially recover by the end of the year, therefore annual strategies or infrequent harvests may leave many losses on the table. The wash sale management and tax lot accounting necessary to support more frequent harvesting quickly becomes overwhelming in a multi-asset portfolio—especially with regular deposits, dividends, and rebalancing. In short, an effective loss harvesting algorithm should be able to maximize harvesting opportunities across a full range of volatility scenarios, without sacrificing the investor’s global asset allocation. Existing strategies and their limitations Every tax-loss harvesting strategy shares the same basic goal: to maximize a portfolio’s after-tax returns by realizing built-in losses while minimizing the negative impact of wash sales. Approaches to tax-loss harvesting differ primarily in how they handle the proceeds of the harvest to avoid a wash sale. Below are the three strategies commonly employed by manual and algorithmic implementations. After selling a security that has experienced a loss, existing strategies would likely have you: Existing strategy Problem Delay reinvesting the proceeds of a harvest for 30 days, thereby ensuring that the repurchase will not trigger a wash sale. While it’s the easiest method to implement, it has a major drawback: no market exposure. This hurts portfolio returns over the long term, and could offset any potential benefit from tax-loss harvesting. Reallocate the cash entirely into one or more different asset classes in the portfolio. This method throws off an investor’s desired asset allocation. Additionally, such purchases may block other harvests over the next 30 days by setting up potential wash sales in those other asset classes. Switch back to original security after 30 days from the replacement security. Common manual approach, also used by some automated investing services. A switchback can trigger short-term capital gains when selling the replacement security, reducing the tax benefit of the harvest. Even worse, this strategy can leave an investor owing more tax than if it did nothing. The hazards of switchbacks In the 30 days leading up to the switchback, two things can happen: the replacement security can drop further, or go up. If it goes down, the switchback will realize an additional loss. However, if it goes up, which is what any asset with a positive expected return is expected to do over any given period, the switchback will realize short-term capital gains (STCG)—kryptonite to a tax-efficient portfolio management strategy. An attempt to mitigate this risk could be setting a higher threshold based on volatility of the asset class—only harvesting when the loss is so deep that the asset is unlikely to entirely recover in 30 days. Of course, there is still no guarantee that it will not, and the price paid for this buffer is that your lower-yielding harvests will also be less frequent than they could be with a more sophisticated strategy. Examples of negative tax arbitrage Negative tax arbitrage with automatic 30-day switchback An automatic 30-day switchback can destroy the value of the harvested loss, and even increase tax owed, rather than reduce it. A substantial dip presents an excellent opportunity to sell an entire position and harvest a long-term loss. Proceeds will then be re-invested in a highly correlated replacement (tracking a different index). 30 days after the sale, the dip proved temporary and the asset class more than recovered. The switchback sale results in STCG in excess of the loss that was harvested, and actually leaves the investor owing tax, whereas without the harvest, they would have owed nothing. Due to a technical nuance in the way gains and losses are netted, the 30- day switchback can result in negative tax arbitrage, by effectively pushing existing gains into a higher tax rate. When adding up gains and losses for the year, the rules require netting of like against like first. If any long-term capital gain (LTCG) is present for the year, you must net a long-term capital loss (LTCL) against that first, and only then against any STCG. Negative tax arbitrage when unrelated long-term gains are present Now let’s assume the taxpayer realized a LTCG. If no harvest takes place, the investor will owe tax on the gain at the lower LTCG rate. However, if you add the LTCL harvest and STCG switchback trades, the rules now require that the harvested LTCL is applied first against the unrelated LTCG. The harvested LTCL gets used up entirely, exposing the entire STCG from the switchback as taxable. Instead of sheltering the highly taxed gain on the switchback, the harvested loss got used up sheltering a lower-taxed gain, creating far greater tax liability than if no harvest had taken place. In the presence of unrelated transactions, unsophisticated harvesting can effectively convert existing LTCG into STCG. Some investors regularly generate significant LTCG (for instance, by gradually diversifying out of a highly appreciated position in a single stock). It’s these investors, in fact, who would benefit the most from effective tax-loss harvesting. Negative tax arbitrage with dividends Negative tax arbitrage can result in connection with dividend payments. If certain conditions are met, some ETF distributions are treated as “qualified dividends”, taxed at lower rates. One condition is holding the security for more than 60 days. If the dividend is paid while the position is in the replacement security, it will not get this favorable treatment: under a rigid 30-day switchback, the condition can never be met. The Betterment solution Summary: Betterment’s tax-loss harvesting approaches tax-efficiency holistically, seeking to optimize transactions, including customer activity. The benefits tax-loss harvesting seeks to deliver, include: No exposure to short-term capital gains in an attempt to harvest losses. Through our proprietary Parallel Position Management (PPM) system, a dual-security asset class approach enforces preference for one security without needlessly triggering capital gains in an attempt to harvest losses, all without putting constraints on customer cash flows. No negative tax arbitrage traps associated with less sophisticated harvesting strategies (e.g., 30-day switchback), making tax-loss harvesting especially suited for those generating large long-term capital gains on an ongoing basis. Tax loss preservation logic extended to user-realized losses, not just harvested losses, automatically protecting both from the wash sale rule. In short, user withdrawals always sell any losses first. Minimize disallowed losses through overlap with a Betterment IRA/401(k). We generally use a tertiary ticker system to eliminate the possibility of permanently disallowed losses triggered by subsequent IRA/401(k) activity. This makes TLH ideal for those who invest in both taxable and tax-advantaged accounts. Harvests also take the opportunity to rebalance across all asset classes, rather than re-invest solely within the same asset class. This further reduces the need to rebalance during volatile stretches, which means fewer realized gains, and higher tax alpha. Through these innovations, tax-loss harvesting creates significant value over manually-serviced or less sophisticated algorithmic implementations. Tax-loss harvesting is accessible to investors —fully automated, effective, and at no additional cost. Parallel securities To ensure that each asset class is supported by optimal securities in both primary and alternate (secondary) positions, we screened by expense ratio, liquidity (bid-ask spread), tracking error vs. benchmark, and most importantly, covariance of the alternate with the primary.1 While there are small cost differences between the primary and alternate securities, the cost of negative tax arbitrage from tax-agnostic switching vastly outweighs the cost of maintaining a dual position within an asset class. Tax-loss harvesting features a special mechanism for coordination with IRAs/401(k)s where we pick a third (tertiary) security in each harvestable asset class where possible. While these have a higher cost than the primary and alternate, they are not expected to be utilized often, and even then, for short durations (more below in IRA/401(k) protection). However, if no suitable tertiary exists beyond the secondary used in the taxable version of the portfolio strategy, certain security groups in Betterment-constructed portfolios will not have tertiary tickers assigned in the tax-advantaged strategy. While Betterment generally constructs portfolios to minimize this risk, clients should be aware that in this scenario, rebalancing can result in wash sales, and that if the replacement purchase occurs in an IRA account, the loss is permanently disallowed. Parallel position management As demonstrated, the unconditional 30-day switchback to the primary security is problematic for a number of reasons. To fix those problems, we engineered a platform to support tax-loss harvesting, which seeks to tax-optimize user and system-initiated transactions: the Parallel Position Management (PPM) system. PPM allows each asset class to contain a primary security to represent the desired exposure while maintaining alternate and tertiary securities that are closely correlated securities, should that result in a better after-tax outcome. PPM provides several improvements over the switchback strategy. First, unnecessary gains are minimized. Second, the parallel security (could be primary or alternate) serves as a safe harbor to reduce potential wash sales—not just from harvest proceeds, but any cash inflows. Third, the mechanism seeks to protect not just harvested losses, but losses realized by the customer as well. PPM not only facilitates effective opportunities for tax-loss harvesting, but also extends maximum tax-efficiency to customer-initiated transactions. Every customer withdrawal is a potential harvest (losses are sold first). Deposits and dividends are used to rebalance your portfolio. When available cash is reinvested, it is generally routed to the parallel position that would reduce wash sales, while working toward the target allocation. PPM has a preference for the primary security when rebalancing and for all cash flow events—but always subject to tax considerations. This is how PPM behaves under various conditions: Transaction PPM behavior Withdrawals and sales from rebalancing Sales default out of the alternate position (if such a position exists), but not at the expense of triggering STCG—in that case, PPM will sell lots of the primary security first. Rebalancing will attempt to stop short of realizing STCG. Taxable gains are minimized at every decision point—STCG tax lots are the last to be sold on a user withdrawal. Deposits, buys from rebalancing, and dividend reinvestments PPM directs inflows to underweight asset classes, and within each asset class, into the primary, unless doing so incurs greater wash sale costs than buying the alternate. Harvest events TLH harvests can come out of the primary into the alternate, or vice versa, depending on which harvest has a greater expected value. After an initial harvest, it could make sense at some point to harvest back into the primary, to harvest more of the remaining primary into the alternate, or to do nothing. Wash sale management Managing cash flows across both taxable and IRA/401(k) accounts without washing realized losses is a complex problem. Tax-loss harvesting operates without constraining the way that customers prefer contributing to their portfolios. With the benefit of parallel positions, Betterment weighs wash sale implications of deposits, withdrawals and dividend reinvestment. This system protects not just harvested losses, but also losses realized through withdrawals. Minimizing wash sale through tertiary tickers in IRA/401(k) Because IRA/401(k) wash sales are particularly unfavorable—the loss is disallowed permanently—tax-loss harvesting uses a tertiary ticker system to seek to prevent losses realized in the taxable account from being washed by subsequent deposits into an IRA/401(k) where possible. Let’s look at an example of how tax-loss harvesting handles a potentially disruptive IRA inflow with a tertiary ticker when there are realized losses to protect, using real market data for a Developed Markets asset class. The customer starts with a position in VEA, the primary security, in both the taxable and IRA accounts. We harvest a loss by selling the entire taxable position, and then repurchasing the alternate security, SCHF. Loss harvested in VEA Two weeks pass, and the customer makes a withdrawal from the taxable account (the entire SCHF position, for simplicity), intending to fund the IRA. In those two weeks, the asset class dropped more, so the sale of SCHF also realized a loss. The VEA position in the IRA remains unchanged. Customer withdrawal sells SCHF at a loss A few days later, the customer contributes to his IRA, and $1,000 is allocated to the Developed Markets asset class, which already contains some VEA. Despite the fact that the customer no longer holds any VEA or SCHF in his taxable account, buying either one in the IRA would permanently wash a valuable realized loss. The Tertiary Ticker System automatically allocates the inflow into the third option for developed markets, IEFA. IRA deposit into tertiary Ticker Both losses have been preserved, and the customer now holds VEA and IEFA in his IRA, maintaining desired allocation at all times. Because no capital gains are realized in an IRA/401(k), there is no harm in switching out of the IEFA position and consolidating the entire asset class in VEA when there is no danger of a wash sale. The result: Customers using TLH who also have their IRA/401(k) assets with Betterment can know that Betterment will seek to protect valuable realized losses whenever they deposit into their IRA/401(k), whether it’s lump rollover, auto-deposits or even dividend reinvestments. Smart rebalancing Lastly, tax-loss harvesting directs the proceeds of every harvest to rebalance the entire portfolio, the same way that a Betterment account handles any incoming cash flow (deposit, dividend). For portfolios with a cash allocation, if cash is below its target allocation at the time of the TLH transaction, proceeds will first be applied to increase cash up to target, and only any remaining available cash is invested in securities; if cash is above its target, the excess cash above target will be invested in securities along with the harvest proceeds as part of the TLH transaction. Recognizing every harvest as a rebalancing opportunity further reduces the need for additional selling in times of volatility, further reducing tax liability. As always, fractional shares allow the inflows to be allocated with precision. Tax-loss harvesting model calibration Summary: To make harvesting decisions, tax-loss harvesting optimizes around multiple inputs, derived from rigorous Monte Carlo simulations. The decision to harvest is made when the benefit, net of cost, exceeds a certain threshold. The potential benefit of a harvest is discussed in detail below (“Results”). Unlike a 30-day switchback strategy, tax-loss harvesting does not incur the expected STCG cost of the switchback trade. Therefore, “cost” consists of three components: trading expense, execution expense, and increased cost of ownership for the replacement asset (if any). Trading costs are included in the wrap fee paid by Betterment customers. Tax-loss harvesting is engineered to factor in the other two components, configurable at the asset level, and the resulting cost approaches negligible. Bid-ask spreads for the bulk of harvestable assets are narrow. We seek funds with expense ratios for the major primary/alternate ETF pairs that are close, and in the case where a harvest back to the primary ticker is being evaluated, that difference is actually a benefit, not a cost. There are two general approaches to testing a model’s performance: historical backtesting and forward-looking simulation. Optimizing a system to deliver the best results for only past historical periods is relatively trivial, but doing so would be a classic instance of data snooping bias. Relying solely on a historical backtest of a portfolio composed of ETFs that allow for 10 to 20 years of reliable data when designing a system intended to provide 40 to 50 years of benefit would mean making a number of indefensible assumptions about general market behavior. The superset of decision variables driving tax-loss harvesting is beyond the scope of this paper—optimizing around these variables required exhaustive analysis. Tax-loss harvesting was calibrated via Betterment’s rigorous Monte Carlo simulation framework, spinning up thousands of server instances in the cloud to run through tens of thousands of forward-looking scenarios testing model performance. We have calibrated tax-loss harvesting in a way that we believe optimizes its effectiveness given expected future returns and volatility, but other optimizations could result in more frequent harvests or better results depending on actual market conditions. Best practices for tax-loss harvesting Summary: Tax-loss harvesting can add some value for most investors, but high earners with a combination of long time horizons, ongoing realized gains, and plans for some charitable disposition will reap the largest benefits. This is a good point to reiterate that tax-loss harvesting delivers value primarily due to tax deferral, not tax avoidance. A harvested loss can be beneficial in the current tax year to varying degrees, but harvesting that loss generally means creating an offsetting gain at some point in the future. If and when the portfolio is liquidated, the gain realized will be higher than if the harvest never took place. Let’s look at an example: Year 1: Buy asset A for $100. Year 2: Asset A drops to $90. Harvest $10 loss, repurchase similar Asset B for $90. Year 20: Asset B is worth $500 and is liquidated. Gains of $410 realized (sale price minus cost basis of $90) Had the harvest never happened, we’d be selling A with a basis of $100, and gains realized would only be $400 (assuming similar performance from the two correlated assets.) Harvesting the $10 loss allows us to offset some unrelated $10 gain today, but at a price of an offsetting $10 gain at some point in the future. The value of a harvest largely depends on two things. First, what income, if any, is available for offset? Second, how much time will elapse before the portfolio is liquidated? As the deferral period grows, so does the benefit—the reinvested savings from the tax deferral have more time to grow. While nothing herein should be interpreted as tax advice, examining some sample investor profiles is a good way to appreciate the nature of the benefit of tax-loss harvesting. Who benefits most? The Bottomless Gains Investor: A capital loss is only as valuable as the tax saved on the gain it offsets. Some investors may incur substantial capital gains every year from selling highly appreciated assets—other securities, or perhaps real estate. These investors can immediately use all the harvested losses, offsetting gains and generating substantial tax savings. The High Income Earner: Harvesting can have real benefits even in the absence of gains. Each year, up to $3,000 of capital losses can be deducted from ordinary income. Earners in high income tax states (such as New York or California) could be subject to a combined marginal tax bracket of up to 50%. Taking the full deduction, these investors could save $1,500 on their tax bill that year. What’s more, this deduction could benefit from positive rate arbitrage. The offsetting gain is likely to be LTCG, taxed at around 30% for the high earner—less than $1,000—a real tax savings of over $500, on top of any deferral value. The Steady Saver: An initial investment may present some harvesting opportunities in the first few years, but over the long term, it’s increasingly unlikely that the value of an asset drops below the initial purchase price, even in down years. Regular deposits create multiple price points, which may create more harvesting opportunities over time. (This is not a rationale for keeping money out of the market and dripping it in over time—tax-loss harvesting is an optimization around returns, not a substitute for market exposure.) The Philanthropist: In each scenario above, any benefit is amplified by the length of the deferral period before the offsetting gains are eventually realized. However, if the appreciated securities are donated to charity or passed down to heirs, the tax can be avoided entirely. When coupled with this outcome, the scenarios above deliver the maximum benefit of TLH. Wealthy investors have long used the dual strategy of loss harvesting and charitable giving. Even if an investor expects to mostly liquidate, any gifting will unlock some of this benefit. Using losses today, in exchange for built-in gains, offers the partial philanthropist a number of tax-efficient options later in life. Who benefits least? The Aspiring Tax Bracket Climber: Tax deferral is undesirable if your future tax bracket will be higher than your current. If you expect to achieve (or return to) substantially higher income in the future, tax-loss harvesting may be exactly the wrong strategy—it may, in fact, make sense to harvest gains, not losses. In particular, we do not advise you to use tax-loss harvesting if you can currently realize capital gains at a 0% tax rate. Graduate students, those taking parental leave, or just starting out in their careers should ask “What tax rate am I offsetting today” versus “What rate can I reasonably expect to pay in the future?” The Scattered Portfolio: Tax-loss harvesting is carefully calibrated to manage wash sales across all assets managed by Betterment, including IRA assets. However, the algorithms cannot take into account information that is not available. To the extent that a Betterment customer’s holdings (or a spouse’s holdings) in another account overlap with the Betterment portfolio, there can be no guarantee that tax-loss harvesting activity will not conflict with sales and purchases in those other accounts (including dividend reinvestments), and result in unforeseen wash sales that reverse some or all of the benefits of tax-loss harvesting. We do not recommend tax-loss harvesting to a customer who holds (or whose spouse holds) any of the ETFs in the Betterment portfolio in non-Betterment accounts. You can ask Betterment to coordinate tax-loss harvesting with your spouse’s account at Betterment. You’ll be asked for your spouse’s account information after you enable tax-loss harvesting so that we can help optimize your investments across your accounts. The Portfolio Strategy Collector: Electing different portfolio strategies for multiple Betterment goals may cause tax-loss harvesting to identify fewer opportunities to harvest losses than it might if you elect the same portfolio strategy for all of your Betterment goals. The Rapid Liquidator: What happens if all of the additional gains due to harvesting are realized over the course of a single year? In a full liquidation of a long-standing portfolio, the additional gains due to harvesting could push the taxpayer into a higher LTCG bracket, potentially reversing the benefit of tax-loss harvesting. For those who expect to draw down with more flexibility, smart automation will be there to help optimize the tax consequences. The Imminent Withdrawal: The harvesting of tax losses resets the one-year holding period that is used to distinguish between LTCG and STCG. For most investors, this isn’t an issue: by the time that they sell the impacted investments, the one-year holding period has elapsed and they pay taxes at the lower LTCG rate. This is particularly true for Betterment customers because our TaxMin feature automatically realizes LTCG ahead of STCG in response to a withdrawal request. However, if you are planning to withdraw a large portion of your taxable assets in the next 12 months, you should wait to turn on tax-loss harvesting until after the withdrawal is complete to reduce the possibility of realizing STCG. Other impacts to consider Investors with assets held in different portfolio strategies should understand how it impacts the operation of tax-loss harvesting. To learn more, please see the respective disclosures for the following Betterment and third-party portfolios: Socially Responsible Investing, Flexible portfolio, Innovative Technology, Value Tilt, Crypto ETF, Goldman Sachs Tax-Smart Bonds, Goldman Sachs Smart Beta, Target Income built with BlackRock, as well as the disclosure Betterment Advisor Solutions Model Marketplace. Clients in Advisor-designed custom portfolios through Betterment for Advisors should consult their Advisors to understand the limitations of tax-loss harvesting with respect to any custom portfolio. Additionally, as described above, electing one portfolio strategy for one or more goals in your account while simultaneously electing a different portfolio for other goals in your account may reduce opportunities for TLH to harvest losses, as TLH is calibrated to seek to reduce wash sales. Due to Betterment’s monthly cadence for billing fees for advisory services, through the liquidation of securities, tax-loss harvesting opportunities may be adversely affected for customers with particularly high stock allocations, third party portfolios, or flexible portfolios. As a result of assessing fees on a monthly cadence for a customer with only equity security exposure, which tends to be more opportunistic for tax-loss harvesting, certain securities may be sold that could have been used to tax loss harvest at a later date, thereby delaying the harvesting opportunity into the future. This delay would be due to the TLH tool’s effort to reduce instances of triggering the wash sale rule, which forbids a security from being sold only to be replaced with a “substantially similar” security within a 30-day period. Factors which will determine the actual benefit of tax-loss harvesting include, but are not limited to, market performance, the size of the portfolio, the stock exposure of the portfolio, the frequency and size of deposits into the portfolio, the availability of capital gains and income which can be offset by losses harvested, the tax rates applicable to the investor in a given tax year and in future years, the extent to which relevant assets in the portfolio are donated to charity or bequeathed to heirs, and the time elapsed before liquidation of any assets that are not disposed of in this manner. All of Betterment’s trading decisions are discretionary and Betterment may decide to limit or postpone TLH trading on any given day or on consecutive days, either with respect to a single account or across multiple accounts. Tax-loss harvesting is not suitable for all investors. Nothing herein should be interpreted as tax advice, and Betterment does not represent in any manner that the tax consequences described herein will be obtained, or that any Betterment product will result in any particular tax consequence. Please consult your personal tax advisor as to whether TLH is a suitable strategy for you, given your particular circumstances. The tax consequences of tax-loss harvesting are complex and uncertain and may be challenged by the IRS. You and your tax advisor are responsible for how transactions conducted in your account are reported to the IRS on your personal tax return. Betterment assumes no responsibility for the tax consequences to any client of any transaction. See Betterment’s tax-loss harvesting disclosures for further detail. How we calculate the value of tax-loss harvesting Over 2022 and 2023, we calculated that 69% of Betterment customers who employed the strategy saw potential savings in excess of the Betterment fees charged on their taxable accounts for the year. To reach this conclusion, we first identified the accounts to consider, defined as taxable investing accounts that had a positive balance and tax-loss harvesting turned on throughout 2022 and 2023. We excluded trust accounts because their tax treatments can be highly-specific and they made up less than 1% of the data. For each account’s taxpayer, we pulled the short and long term capital gain/loss in the relevant accounts realized in 2022 and 2023 using our trading and tax records. We then divided the gain/loss into those caused by a TLH transaction and those not caused by a TLH transaction. Then, for each tax year, we calculated the short-term gains offset by taking the greater of the short-term loss realized by tax-loss harvesting and the short-term gain caused by other transactions. We did the same for long-term gain/loss. If there were any losses leftover, we calculated the amount of ordinary income that could be offset by taking the greater of the customer’s reported income and $3,000 ($1,500 if the customer is married filing separately) and then taking the greater of that number and the sum of the remaining long-term and short-term losses (after first subtracting any non-tax-loss harvesting losses from ordinary income). If there were any losses leftover in 2022 after all that, we carried those losses forward to 2023. At this point, we had for each customer the amount of short-term gains, long-term gains and ordinary income offset by tax-loss harvesting for each tax year. We then calculated the short-term and long-term capital gains rates using the federal tax brackets for 2022 and 2023 and the reported income of the taxpayer, their reported tax filing status, and their reported number of dependents. We assumed the standard deduction and conservatively did not include state capital gains taxes because some states do not have capital gains tax. We calculated the ordinary income rate including federal taxes, state taxes, and Medicare and Social Security taxes using the user’s reported income, filing status, number of dependents, assumed standard deduction, and age (assuming Medicare and Social Security taxes cease at the retirement age of 67). We then applied these tax rates respectively to the offsets to get the tax bill reduction from each type of offset and summed them up to get the total tax reduction. Then, we pulled the total fees charged to the users on the account in question that were accrued in 2022 and 2023 from our fee accrual records and compared that to the tax bill reduction. If the tax bill reduction was greater than the fees, we considered tax-loss harvesting to have indirectly paid for the fees in the account in question for the taxpayer in question. This was the case for 69% of customers. Your personalized Estimated Tax Savings tool Overview: Betterment’s TLH Estimated Tax Savings Tool is found in your online account and designed to quantify the tax-saving potential of our tax-loss harvesting (TLH) feature. By leveraging both transactional data from Betterment accounts and your self-reported demographic and financial profile information, the tool generates dynamic estimates of realized and potential tax savings. These calculations provide both current-year and cumulative ("all-time") tax savings estimates. Client-centric tax modeling: To personalize estimates, the tool takes into account client financial profile information: your self-reported annual pre-tax income, state of residence, tax filing status (e.g. individual, married filing jointly), and number of dependents. This information helps Betterment create a comprehensive tax profile, estimating your federal and state income tax rates, long-term capital gains (LTCG) rates, and applicable standard deductions. Betterment’s estimated tax savings methodology also incorporates the IRS' cap on ordinary income offsets for capital losses—$3,000 for most individuals or $1,500 if married filing separately, and also incorporates any available carryforward losses. Tax lot analysis and offsetting hierarchy: At the heart of Betterment’s estimated tax savings tool is a detailed analysis of tax-lot level trading data. Betterment tallys TLH-triggered losses (short- and long-term) from other realized capital gains or losses, grouping them by year, and calculates your potential tax benefit by offsetting losses and gains by type according to IRS rules, and allowing excess losses to offset other income types or carry forward to future years. The IRS offset order is applied: Short-term losses offset short-term gains Long-term losses offset long-term gains Remaining short-term losses offset long-term gains Remaining long-term losses offset short-term gains Remaining short-term losses offset ordinary income Remaining long-term losses offset ordinary income Any further losses are carried forward Current year estimated tax savings: Betterment calculates your current year estimated tax savings from TLH based on the IRS numbered offset list above, which is the sum of: Short-term offset represents the tax savings from subtracting your short-term harvested losses and cross-offset long-term harvested losses from current-year short-term capital gains (numbers 1 and 4 above), then multiplying by your estimated federal plus state tax rate. Long-term offset represents the savings from subtracting long-term harvested losses and cross-offset short-term harvested losses from current-year long-term capital gains (numbers 2 and 3 above), multiplied by your estimated long-term capital gains rate. Ordinary income offset captures the savings from applying any remaining harvested losses to your ordinary income up to the allowable limit (numbers 5 and 6 above), multiplied by your estimated federal plus state tax rate. Both short-term and long-term harvested losses may include banked losses from prior years that couldn’t be used at the time. These carryforward losses (number 7 above) are applied in the same way as current-year harvested losses when calculating your tax savings. For the tool, Harvested Losses are all time short- and long-term harvested losses i.e., all harvested losses to date through TLH. Savings from the Short-term offset, long-term offset, and ordinary income offset are summed to yield the current year estimated tax savings. All-time estimated tax savings : Betterment calculates your all-time estimated tax savings from TLH based on the sum of: All-time Long-term harvested losses × LTCG rate All-time Short-term harvested losses × (Federal + State tax rate) For the all-time estimated tax figure, the all-time figures used are all your harvested losses through Betterment’s TLH feature to the present date, and rather than calculate offsets, Betterment assumes that you are able to fully offset your long-term harvested losses and short-term harvested losses with gains. Therefore, we apply the long term capital gains rates and marginal ordinary income rate (which is the sum of your federal and state tax rates) by your total long-term harvested losses and short-term losses, respectively. There is no ordinary income offset in the All-Time Estimate. This simplification does not track when the loss occurred, and therefore, assumes current estimated tax rates were applicable throughout prior years. Assumptions: While this tool provides a powerful estimate of your potential tax benefits from tax-loss harvesting, it is important to understand the assumptions and limitations underlying the estimated tax savings calculations. Estimated tax savings figures presented are estimates—not guarantees—and rely on the information you’ve provided to Betterment. Actual tax outcomes may vary based on your actual tax return and situation when filing. The tool evaluates only the activity within your Betterment accounts and does not take into account any investment activity from external accounts. For the current year calculation, the tool also assumes that you have sufficient ordinary income to fully benefit from capital loss offsets, and for the all-time calculation, the tool provides a tax-dollar estimate of all harvested losses, based on type (short- or long-term) and current tax rates. Additionally, the estimated tax savings calculation simplifies the treatment of certain entities; for example, trusts, business accounts, or other specialized tax structures are not handled distinctly. State-level tax estimates exclude city tax rates and municipal taxes, which may also affect your overall tax situation. The “all-time estimate” shown reflects an approximation of the total tax impact of harvested losses to date—including benefits that have not yet been realized or claimed. While the estimate has its limitations, it provides a clear and actionable view into how tax-smart investing can add value over time. It helps show how harvested losses may lower your tax bill and boost after-tax returns—bringing transparency to a strategy that’s often hard to see in dollar terms. For many investors, it highlights the long-term financial benefits of managing taxes proactively. Conclusion Summary: Tax-loss harvesting can be an effective way to improve your investor returns without taking additional downside risk. -
Backdoor Roths and beyond: The four camps who can benefit from a Roth IRA conversion
Backdoor Roths and beyond: The four camps who can benefit from a Roth IRA conversion Apr 22, 2026 12:00:00 AM A Roth conversion isn't for everyone, but it can unlock tax savings if you're a high earner, facing RMDs, retiring early, or in a low-income year. Key takeaways A Roth conversion means moving money from a traditional retirement account into a Roth IRA, where you pay taxes now in exchange for tax-free qualified withdrawals. It can be a smart move in several scenarios: your income exceeds the eligibility limits for IRAs, you want lower required minimum distributions in retirement, you're planning an early retirement, or you're temporarily in a low tax bracket. Done right, a conversion can lead to savings over time, but timing and tax planning matter enormously. We recommend working with a financial and/or tax specialist before converting. Households with over $100k at Betterment can kick the tires on a Roth conversion with the help of a professional. Roth IRAs and their tax-exempt perks are pretty great—so great that in some scenarios, it can make sense to convert pre-tax dollars from traditional IRAs and 401(k)s into post-tax dollars in a Roth IRA. This is what’s known as a Roth IRA conversion. You’re taking those pre-tax funds and telling Uncle Sam you’d rather pay taxes on them now in exchange for the benefit of tax-free qualified withdrawals down the road. So what scenarios are Roth conversions ideal for? Four in particular: High earners and the “backdoor” Roth conversion – The IRS blocks direct Roth IRA contributions above certain income limits, but there's a workaround. Recent retirees and unwelcome RMDs – Converting traditional retirement account funds now shrinks the mandatory withdrawals that can inflate your tax bill in retirement. Early retirees and the Roth conversion “ladder” – A little advance planning can unlock your retirement savings years before the IRS’s minimum age of 59 ½ for penalty-free withdrawals after a 5-year holding period for each conversion. People experiencing temporary income dips – Take advantage of low (or no) income tax years. High earners and the “backdoor” Roth conversion Did you know the IRS restricts access to Roth IRAs based on income? Shut the front door! Yes, if your income exceeds these limits, you can’t contribute directly to a Roth IRA. But as the saying goes, when one door closes, another door opens. A “backdoor,” more specifically. A “backdoor” Roth entails contributing after-tax dollars first to a traditional IRA, then converting those funds to a Roth IRA. It’s fairly straightforward in two scenarios: You’ve never contributed to a traditional IRA before. Betterment makes it easy to not only open both a traditional and Roth IRA, but to convert those traditional funds with only a few clicks. You’ve made only pre-tax contributions to a traditional, SEP, and/or SIMPLE IRA(s). Thanks to the IRS’s pro rata rule, you’ll need to first move those pre-tax dollars out of their respective accounts and into a traditional 401(k) or 403(b) before you can use the IRA for a backdoor. Now, things can get tricky if you have a mix of both pre- and post-tax funds in any traditional IRAs (Side note: the IRS treats any and all traditional IRAs you have as essentially the same bucket). So before going down the road of a backdoor Roth, or any Roth conversion really, we highly recommend seeking out both financial and tax guidance. In the case of the former, households with $100k at Betterment can get free guidance on a backdoor Roth via live chat. Already a customer and clear that mark? You're already in—just open a chat. Considering making the move? Our Licensed Concierge team is here to help. Recent retirees and unwelcome RMDs The IRS doesn’t let you keep pre-tax funds in your traditional IRAs and 401(k)s indefinitely. Those dollars are meant to be spent, after all. And Uncle Sam wants (or needs) that tax revenue at some point. So starting in your 70s (75 for those born after 1960, 73 for those born 1951-1959), annual required minimum distributions (RMDs) from these accounts kick in, and the withdrawals are taxed accordingly. RMDs aren’t inherently a bad thing, but if your expenses can already be covered from other sources, RMDs can needlessly raise your tax bill. You can get ahead of this and lower your future amount of RMDs by converting traditional funds to a Roth IRA, which is exempt from RMDs, before you reach RMD age. This can be especially beneficial when your income is low and you have extra space in a low tax bracket you can take advantage of. Another benefit is you’ll minimize taxes on Social Security benefits and Medicare premiums later on in retirement. Early retirees and the Roth conversion “ladder” If you want to retire early, even by just a few years, you might encounter a problem: Most of your retirement savings are tied up in tax-advantaged 401(k)s and IRAs, which slap you with a 10% penalty if you withdraw the funds before the age of 59 ½. A few key exceptions to this early withdrawal rule exist, however: Regular contributions to a Roth IRA (not the growth from those contributions) can be withdrawn any time without taxes or penalties. Once regular contributions are exhausted, Roth IRA conversions can be withdrawn penalty-free as well provided you let each conversion sit for at least five years. So with a little advance planning, early retirees can create a “ladder” of penalty-free Roth IRA funds. They convert funds each year, pay income taxes on them at that time (or not, if they play their cards right), wait five years, then withdraw each conversion scot-free. People experiencing temporary income dips Say you find yourself staring at a significantly smaller income for the year. Maybe you’re taking some time away from work, or you work on commission and had a down year. Whatever the reason, that dip in income means you’re currently in a lower tax bracket, and it may be wise to pay taxes on some of your pre-tax investments now at that lower rate compared to the higher rate when your income bounces back. Roth conversions can be powerful, but plan carefully If you find yourself in one of these scenarios, a Roth conversion could be a real opportunity for you. But the difference between a smart conversion and a costly one often comes down to timing, tax planning, and knowing the rules. Before you pull the trigger, it's worth reading up on the most common Roth conversion mistakes—and even better, talking it through with an advisor who can look at your full picture. Betterment Premium gives you access to a team of CERTIFIED FINANCIAL PLANNER® professionals who can help you figure out the right amount to convert, in the right year, for your situation. -
The powerful potential of the tax swap
The powerful potential of the tax swap Apr 16, 2026 12:18:31 PM Your top tax rate will likely ebb and flow over your lifetime. Tax-savvy investing can help you pay when the tide is low. Key takeaways Your tax rate often ebbs and flows over your lifetime, and the gap between your highest- and lowest-earning years represents an opportunity. Tax-deferred investing lets you swap taxes today for a potentially smaller bill in retirement, while keeping more capital compounding in the market. In low-income years, you can do the opposite: pay a lower rate up front, then enjoy tax-free qualified withdrawals down the road. Betterment automates much of the heavy lifting on both strategies. And for more personalized planning, our advisors can help you find the right moves at the right time. Most investors fixate on their returns. But there's a second stat that can quietly work against them: their tax bracket. And unlike market returns, your tax bracket is something you can actually influence. Investors accomplish this by way of tax arbitrage—a tax “swap” of sorts. The core insight is simple: your tax bracket isn't fixed. It changes over your lifetime, and in response to the choices you make. Sometimes the opportunity arises to swap a tax for a lower (and/or later) one, and these moves can make a meaningful difference in how much of your investing returns you actually keep in the long run. First, a quick tour of how taxes work The U.S. tax system is progressive, meaning income is taxed in layers. Each slice is taxed at a higher rate than the one below it, so while it’s common to hear about your tax bracket (as in, singular), your income often falls into multiple brackets (as in, plural). Tax swaps are all about maneuvering around your top tax bracket and its associated tax rate. As your income grows over time, your last few dollars earned will sometimes break into a higher bracket. And vice versa, when you earn less in a given year—say in retirement or in between jobs—you may slide down a bracket or two. These movements present an opportunity. Two common types of tax swaps Tax deferral: Reducing taxable income today, and buying time for compound interest to do its thing The first example is also the most straightforward: swap a tax today for one down the road. For many people in their peak earning years, that future point is retirement. Let’s say you're hypothetically in the 22% income tax bracket today, but expect to be in the 12% bracket in retirement. In this scenario, every dollar you defer is a dollar that gets taxed nearly half as much, although individual results will vary. Just as importantly, however, this frees up more capital that can potentially benefit from decades of compound growth. Traditional IRAs and 401(k)s are the workhorses here, letting you invest more than $30,000 of income before it gets taxed. In the case of traditional IRAs, it should be noted, those tax benefits phase out at certain income levels. Beyond capped retirement accounts, two strategies can help you maximize the benefits of deferring taxes: Tax-loss harvesting can sprinkle the same advantages on a portion of your taxable investing, with theoretically no limits—and as a side benefit, any leftover harvested losses can offset a higher tax on up to $3,000 of ordinary income each year. Asset location, also known as Tax Coordination at Betterment, can help shield more of your tax-heavy assets in tax-deferred accounts. Both features are fully-automated at Betterment and just a few of the ways it can pay to automate your investing. Filling up low brackets: Take advantage of low or no(!) tax rate years If deferring taxes is about pushing taxes into the future, the second type of tax swap is its polar opposite: pulling them forward into the present when your cash flow dips below its normal cruising altitude. Think early in your career, a gap year between jobs, or early retirement. Filling up low brackets strategically requires advance planning, which is why we recommend talking things through with both a financial and tax advisor. Broadly-speaking, you have a few strategies at your disposal: Roth IRA/401(k) contributions | Paying taxes on your investing now so future growth can be tapped tax-free via qualified withdrawals. Roth IRA conversions | Converting pre-tax traditional IRA/401(k) contributions to a Roth IRA and paying taxes now. Tax-gain harvesting | Strategically selling appreciated investments in a taxable account to realize gains without owing federal income tax, then reinvesting the proceeds. If you play your cards right here, you could pull off the most impressive tax swap of all: a 0% tax rate. That's thanks to the favorable treatment of long-term capital gains, the profits from selling investments held longer than a year. Unlike short-term gains, which are taxed as ordinary income, long-term gains have their own brackets, which are both lower and fewer in number: Tax year 2026 long-term capital gains tax rates Tax rate Single filers Married filing jointly 0% $0-$49,450 $0-$98,900 15% $49,451-$545,500 $98,901-$613,700 20% $545,501 or more $613,701 or more Source: IRS This means investors, assuming they have no other sources of income, can enjoy tens of thousands of dollars in qualified tax-free profits from their taxable investing accounts each year, and even more when factoring in the standard deduction. How Betterment makes it easy You could map all of this out yourself—figuring out your current bracket/s, projecting where you'll land in retirement, deciding which accounts to prioritize, and revisiting it all every time your life changes. It's doable. It's also a lot. Or you can let us do the lion’s share of the work. Tell us your household pre-tax income and tax filing status, and we’ll recommend whether it makes sense to lean into tax-deferred accounts. And for even more personalized guidance, there’s Betterment Premium. Our team of advisors can help you think through the timing of Roth conversions and other strategies that benefit from a human eye. We also recommend looping in a tax advisor, who can pressure-test the plan from a tax filing perspective. A savvy trade hiding in plain sight Tax swaps aren’t about gaming the system. They’re about using the tax code the way it was designed to be used—strategically, patiently, and with an eye on the long game. Most investors leave this opportunity on the table not because it's out of reach, but because it feels complicated. It doesn't have to be. Whether you're just starting to think about tax-smart investing or looking to get more intentional about your retirement strategy, Betterment can help you find and act on the opportunities that make sense for you. -
Three ways it can pay to automate your investing
Three ways it can pay to automate your investing Jan 30, 2026 6:00:00 AM Our managed offering adds value beyond a DIY approach. Here’s how. Key takeaways Portfolio construction is just the beginning. Betterment’s automated investing is designed to help you manage risk, maximize returns, and minimize leg work. Tax-smart features help you keep more of what you earn. Fully-automated Tax Coordination and tax-loss harvesting seek out efficiencies hard to replicate by hand. Navigation helps keep your goals on track. Automated rebalancing, effortless glide paths, and recurring deposits make it easier to stay the course through market ups and downs. Peace of mind is part of the return. Automation frees up time and headspace, letting you live your life instead of worrying about your portfolio. With the arrival of self-directed investing at Betterment, you can choose from thousands of individual stocks and ETFs on your own, including the very same funds we research and select for our curated portfolios. So if you can now buy the same low-cost investments, why pay someone (i.e., us) to manage them for you? It’s a fair question, and to help answer it, it helps to understand why our portfolio construction is just the beginning of the story. It's not just the Betterment portfolio you see today, but the one you see tomorrow (and in the weeks, months, and years that follow) that captures the full value of our expertise and technology. The ongoing optimization and evolution of your portfolio, in other words, is where our automated investing really shines. Sometimes the benefits are tangible. Sometimes they’re emotional. But regardless of how you frame it, we’re constantly working in the background to deliver value in three big ways. Tax savings: keeping more of what you earn Navigation: keeping your investing on-track Calm: keeping your sanity—and your spare time 1. Tax savings: keeping more of what you earn One of the most reliable ways to increase your returns is lowering the taxes owed on your investments. And here's the first way Betterment’s managed portfolios can pay off. Our trading algorithms take tax optimization to a level that’s practically impossible to replicate on your own. Take our Tax Coordination feature, which uses the flexibility of our portfolios to locate assets strategically across Betterment traditional IRAs/401(k)s, Roth IRAs/401(k)s, and taxable accounts. This mathematically-rigorous spin on asset location can help more of your earnings grow tax-free. Then there’s our fully-automated tax-loss harvesting, a feature designed to free up money to invest that would've otherwise gone to Uncle Sam. Our technology regularly scans accounts to identify harvesting opportunities, then goes to work. It’s how we harvested nearly $60 million in losses for customers during the tariff-induced market volatility of Spring 2025. Betterment does not provide tax advice. TLH is not suitable for all investors. Learn more. It’s also a big reason why nearly 70% of customers using our tax-loss harvesting feature had their taxable advisory fee covered by likely tax savings.1 And with the upcoming addition of direct indexing to Betterment’s automated investing, our harvesting capabilities will only continue to grow. 1Based on 2022-2023. Tax Loss Harvesting (TLH) is not suitable for all investors. Consider your personal circumstances before deciding whether to utilize Betterment’s TLH feature. Fee coverage and estimated tax savings based on Betterment internal calculations. See more in disclosures. 2. Navigation: keeping your investing on-track It’s easy to veer off-course when managing your own investing. Life happens, calendars fill up, and the next thing you know, your portfolio starts to drift. When you pay for automated investing, however, you not only get our guidance upfront, you benefit from technology designed to get you to your destination with less effort. As markets ebb and flow, for example, we automatically rebalance your portfolio to maintain your desired risk level. And the “glide path” that automatically lowers your risk as your goal nears? It just happens in eligible portfolios. No research or calendar reminders needed. Our management also helps steer your investing toward a time-tested path to long-term wealth. Most of our portfolios are globally diversified so you take advantage when overseas markets outperform. And we encourage recurring deposits so you buy more shares when prices are low. Recent research by Morningstar helps quantify the value of this “dollar-cost averaging” approach. They found investors lost out on roughly 15% of the returns their funds generated due in large part to jumping in and out of the market. Betterment customers using recurring deposits, meanwhile, earned nearly ~4% higher annual returns.2 It turns out it’s easier to stay the course with a little help. 2Based on Betterment’s internal calculations for the Core portfolio over 5 years. Users in the “auto-deposit on” groups earned an additional 0.6% over the last year and 1.6% annualized over 10 years. See more in disclosures. 3. Calm: Keeping your sanity—and your spare time Our automation can save you time—two hours for each rebalance alone3—but the value of automating your investing is more than just time saved. It’s quality time spent. How much of your finite energy, in other words, are you spending worrying about your money? We can’t erase all of your anxiety, but our team and our tech can empower you to build wealth with confidence and ease, with an emphasis on the ease. 3Based on internal data for a client with one account subject to Betterment’s TaxMin methodology and no other tax features enabled. Betterment will not automatically rebalance a portfolio until it meets or exceeds the required account balance. Between market volatility and a constant barrage of scary headlines, the world is stressful enough right now. There’s little need to add portfolio optimization and upkeep to the list. That is, of course, unless you enjoy it. But many of us don’t. The majority of Betterment customers we surveyed said they hold most of their assets in managed accounts, with self-directed investing serving as a side outlet for exploration. That’s why we offer both ways to invest at Betterment. The payoff is personal Investing performance and price are often measured down to the hundredth of a percentage point. That’s “zero point zero one percent” (0.01%), also known as a “basis point" or "bip" for short. Here at Betterment, it’s our mission to make every one of the 25 bips we most commonly charge worth it. We measure our portfolio’s performance after those fees, so you see what you’ve really earned. And we don’t stop there. With direct indexing and fully paid securities lending coming soon to automated investing, you’ll get even more ways to make your money work harder. -
Betterment's tax lot selection methodology
Betterment's tax lot selection methodology Dec 23, 2025 12:00:00 AM Selecting tax lots efficiently can address and reduce the tax impact of your investments. Every time you have a transaction in a Betterment account that involves a sale—such as a withdrawal, transfer, or rebalance—Betterment’s technology determines (1) which security or securities to sell, and (2) within each security, which specific tax lots to sell. With tax-smart technology, selecting tax lots efficiently can address and reduce the tax impact of your investments. Selecting tax lots efficiently can address and reduce the tax impact of your investments. When choosing which tax lots of a security to sell, our method factors in both cost basis as well as duration held. When you make a withdrawal for a certain dollar amount from an investment account, your broker converts that amount into shares, and sells that number of shares. Assuming you are not liquidating your entire portfolio, there's a choice to be made as to which of the available shares are sold. Every broker has a default method for choosing those shares, and that method can have massive implications for how the sale is taxed. Betterment's default method seeks to reduce your tax impact when you need to sell shares. Basis reporting 101 The way investment cost basis is reported to the IRS was changed as a result of legislation that followed the financial crisis in 2008. In the simplest terms, your cost basis is what you paid for a security. It’s a key attribute of a “tax lot”—a new one of which is created every time you buy into a security. For example, if you buy $450 of Vanguard Total Stock Market ETF (VTI), and it’s trading at $100, your purchase is recorded as a tax lot of 4.5 shares, with a cost basis of $450 (along with date of purchase.) The cost basis is then used to determine how much gain you’ve realized when you sell a security, and the date is used to determine whether that gain is short or long term. However, there is more than one way to report cost basis, and it’s worthwhile for the individual investor to know what method your broker is using—as it will impact your taxes. Brokers report your cost basis on Form 1099-B, which Betterment makes available electronically to customers each tax season. Tax outcomes through advanced accounting When you buy the same security at different prices over a period of time, and then choose to sell some (but not all) of your position, your tax result will depend on which of the shares in your possession you are deemed to be selling. The default method stipulated by the IRS and typically used by brokers is FIFO (“first in, first out”). With this method, the oldest shares are always sold first. This method is the easiest for brokers to manage, since it allows them to go through your transactions at the end of the year and only then make determinations on which shares you sold (which they must then report to the IRS.) FIFO may get somewhat better results than picking lots at random because it avoids triggering short-term gains if you hold a sufficient number of older shares. As long as shares held for more than 12 months are available, those will be sold first. Since short-term tax rates are typically higher than long-term rates, this method can avoid the worst tax outcomes. However, FIFO's weakness is that it completely ignores whether selling a particular lot will generate a gain or loss. In fact, it's likely to inadvertently favor gains over losses; the longer you've held a share, the more likely it's up overall from when you bought it, whereas a recent purchase might be down from a temporary market dip. Fortunately, the IRS allows brokers to offer investors a different default method in place of FIFO, which selects specific shares by applying a set of rules to whatever lots are available whenever they sell. While Betterment was initially built to use FIFO as the default method, we’ve upgraded our algorithms to support a more sophisticated method of basis reporting, which aims to result in better tax treatment for securities sales in the majority of circumstances. Most importantly, we’ve structured it to replace FIFO as the new default—Betterment customers don’t need to do a thing to benefit from it. Betterment’s TaxMin method When a sale is initiated in a taxable account, Betterment’s algorithm first determines what security or securities to sell in order to reduce drift in the portfolio, bringing the portfolio closer to its target allocation as a part of the transaction. Once the algorithm has identified which security to sell, it needs to make a choice as to which specific tax lots of that holding will be sold. For example, if the algorithm identifies a client’s portfolio should sell VTI, and the portfolio holds 10 shares of VTI purchased at different times with different cost basis, it next needs to determine which of the 10 shares of VTI to sell that will minimize taxes on the transaction. This second choice, which specifies tax lots to sell, follows a set of rules which we call TaxMin. This method is more granular in its approach and will aim to improve the tax impact for most transactions, as compared to FIFO. How does the TaxMin method work? Realizing taxable losses instead of gains and allowing short-term gains to mature into long-term gains (which are generally taxed at a lower rate) generally results in a lower tax liability in the long run. Accordingly, TaxMin also considers the cost basis of the lot, with the goal of realizing losses before any gains, regardless of when the shares were bought. Generally, the algorithm is designed to we sell shares in a way that is intended to prioritize realizing available losses (which can mean that we can prioritize selling tax lots with a long-term loss or a short-term loss, depending on which loss type would result in minimizing taxes for the particular transaction), and when losses are not available, evaluating which securities can be sold with the lowest capital gains (similarly, which can prioritize tax lots with only short-term capital gains over those with long-term capital gains). If the identified security to sell has both short-term capital gains and long-term capital gains, Betterment’s system will generally prioritize realizing the long-term capital gains first, and if needed, followed by short-term capital gains. generating short-term capital losses, then long-term capital losses, followed by long-term capital gains and then lastly, short-term capital gains. In short, the algorithm targets selling tax looks through each category before moving to the next, but within each category, lots with the highest cost basis in order to minimize taxes on the overall transaction are targeted first. In the case of a gain, the higher the cost basis, the smaller the gain, which results in a lower tax burden. In the case of a loss, the opposite is true: the higher the cost basis, the bigger the loss (which can be beneficial, since losses can be used to offset gains). 1 TaxMin is designed to generally minimize taxes because it prioritizes selling tax lots at a loss before it sells tax lots at a gain. However, for certain groups – investors in relatively low income tax brackets, especially those who expect to be subject to higher tax rates in the future, and those who can recognize capital gains at a 0% tax rate – it may be more beneficial to prioritize selling assets at a gain in the short run. Investors with different individual tax circumstances should consider whether other offerings might provide more tax efficiency in these scenarios. Also, clients should be aware that when a client makes a change resulting in the sale of the entirety of a particular holding in a taxable account (such as a full withdrawal or certain portfolio strategy changes), tax minimization may not apply because all lots will be sold in the transaction. A simple example If you owned the following lots of the same security, one share each, and wanted to sell one share on July 1, 2021 at the price of $105 per share, you would realize $10 of long term capital gains if you used FIFO. With TaxMin, the same trade would instead realize a $16 short term loss. If you had to sell two shares, FIFO would get you a net $5 long term gain, while TaxMin would result in a $31 short term loss. To be clear, you pay taxes on gains, while losses can help reduce your bill. Purchase Price ($) Purchase Date Gain or Loss ($) FIFO Selling order TaxMin Selling order $95 1/1/20 +10 1 4 $110 6/1/20 -5 2 3 $120 1/1/21 -15 3 2 $100 2/1/21 +5 4 5 $121 3/1/21 -16 5 1 What can you expect? TaxMin automatically works to reduce the tax impact of your investment transactions in a variety of circumstances. Depending on the transaction, the tax-efficiency of various tax-lot selection approaches may vary based on the individual’s specific circumstances (including, but not limited to, tax bracket and presence of other gains or losses.) Note that Betterment is not a tax advisor and your actual tax outcome will depend on your specific tax circumstances—consult a tax advisor for licensed advice specific to your financial situation. -
How donating shares instead of dollars can lead to tax-free investing
How donating shares instead of dollars can lead to tax-free investing Dec 1, 2025 8:00:00 AM And how we make it easy. Key takeaways 2017 legislation weakened the federal income tax incentive for donating to charity. Donating and replacing taxable shares, however, can unlock a new avenue for tax savings. Pairing the strategy with tax-loss harvesting can lead to even more savings. Betterment gives you two easy ways to donate shares: directly to one of our partner charities, or through a donor-advised fund. Donating to charity isn't the big tax write-off it used to be. Not since the 2017 Tax Cuts and Jobs Act watered down the charitable tax deduction. But altruistic investors such as yourself have another tax-saving option at your disposal: donating shares. In this article, we’ll walk you through: How donating (then replacing) shares resets their tax bill How adding tax-loss harvesting can plus-up the savings How we make it easy to donate shares How donating (then replacing) shares resets their tax bill Let's start with a couple prerequisites up front: You can only donate appreciated shares, meaning ones that have gained in value. We require that you've held them for at least a year to maximize the potential tax savings. You can only donate shares from a taxable investing account. That means tax-advantaged accounts like 401(k)s and IRAs—with one exception for those 70 ½ or older—are off the table. So if you'd like to start leveraging this tax strategy, you'll need to first open and fund a taxable investing account. Similar to the mechanics of tax-loss harvesting, donating shares lowers your taxes thanks to a little something called cost basis. Cost basis is the price you pay for a share. It's how the IRS calculates the profits (aka capital gains) on your investing, and by extension your taxes owed on that investing. By donating and (most importantly) replacing shares, you reset the price paid for that slice of your investing. This means a share that had increased in value by say, 20%, suddenly becomes, in the eyes of the IRS, a share that hasn't appreciated at all. It's as if all the profit to that point never happened. Don't worry; the capital gains are still very much there. And you're wealthier for it. But the taxes owed when you ultimately sell those investments will be lower than if you had never donated. How adding tax-loss harvesting can plus-up the savings Tax-loss harvesting (TLH) helps you defer taxes down the road, freeing up more cash to invest now. And it does this by letting you deduct taxes today in exchange for a higher tax bill in the future. You can think of it like handing Uncle Sam an IOU come tax time. But guess what happens when you donate a share that was originally part of a harvest? You erase its entire tax bill—IOU and all—up to that point. It's one of the few ways you can actually avoid paying taxes altogether on some of your investing. So it’s no wonder why this combo move has long been a favorite of the wealthy. Now, thanks to technology like ours, it's never been easier for everyday investors to do right while reaping the same rewards. How we make it easy to donate shares Before tech like ours helped lower barriers, donating shares required several steps, things like tracking down the charity’s brokerage information, figuring out which shares to give, and filling out the necessary forms. But with Betterment, it’s as easy as logging in on a desktop browser and making a few clicks. We show you exactly how much of your taxable investing is eligible to donate, and our TaxMax technology seeks out the most tax-efficient shares to sell and donate. We also give you two ways to give. Donate directly to more than a dozen partner charities. We don’t charge any processing fees, so your entire donation goes directly to them. Open a donor-advised fund (DAF) with our partners at Daffy and donate to that, then choose from up to 1.5 million nonprofits, schools, and faith-based organizations while your funds stay invested. You get the tax deduction up front and can then automate your giving or disperse funds as you go. DAFs have historically come with high minimums, high fees, and dated technology, but Daffy is doing its best to change that. DAFs compared Daffy Fidelity Schwab Vanguard Minimum to open $0 $0 $0 $25,000 Minimum annual cost $36 0.60% or $100 0.60% 0.60% or $250 Average investment fee 0.05% 0.54% 0.65% 0.06% Source: Daffy Give smarter. Save bigger. Feel better. By donating and replacing shares, you can give your taxable investing a fresh start. Pair it with tax-loss harvesting, and you could wipe out even more of your tax bill while keeping your money growing. And since Betterment takes care of the tricky parts, from choosing which shares to donate to handling the logistics, giving smarter has never been easier. It’s one simple move that helps your portfolio—and your favorite cause—thrive. -
How our Tax Impact Preview helps investors make savvier sell decisions
How our Tax Impact Preview helps investors make savvier sell decisions Nov 18, 2025 12:30:00 AM Whether using our self-directed or automated investing, our Tax Impact Preview helps you avoid a surprise on your tax bill. Key takeaways Selling stocks and ETFs at a gain creates a tax bill, but most apps don’t show you the impact until it’s too late. Betterment offers Tax Impact Preview to give you upfront transparency before you sell. By showing the tax preview, you have the insights needed to help avoid short-term capital gains taxes by choosing not to sell. Tax Impact Preview is free to use, provides near real-time tax estimates, and helps you make informed investing decisions. You can use it with both self-directed and automated accounts at Betterment. Selling stocks and ETFs for a profit usually results in having to pay taxes. The thing is, most investing apps don’t show you the tax implications when you go to sell. You end up seeing your tax bill when you file taxes months later. This lack of transparency didn’t sit well with us at Betterment, so we did something about it. We built Tax Impact Preview. Unlike other investing apps, our Tax Impact Preview shows you the estimated amount of taxes you may owe on short-term (assets held for a year or less) and long-term capital gains prior to selling a stock or ETF. Three things to know about Betterment’s Tax Impact Preview Before you use Tax Impact Preview, here are three things to know about how it can help you make investing decisions: It’s free to use: Tax Impact Preview is available for all Betterment customers at no additional cost on self-directed and automated investing accounts. It provides a near real-time tax estimate: You get a near real-time tax estimate based on the latest market data for withdrawals or allocation changes before you confirm the transaction. It helps you make informed decisions: It’s important to note that Tax Impact Preview shows you key information to make informed decisions. The preview can be useful in different scenarios, including when you sell a stock or ETF, change asset allocation, or during a Roth conversion—it doesn’t force you to do anything. It empowers you to make investment decisions that fit your goals. How Betterment’s Tax Impact Preview works Betterment’s Tax Impact Preview can be used with all taxable investing accounts. That includes both self-directed investing (buying and selling individual stocks and ETFs) and automated investing (Betterment’s pre-built portfolios). You’ll see the preview when you go to sell a stock or ETF, or when you initiate a sale within a portfolio. Tax impact preview with self-directed investing To see your tax impact preview, follow these steps to initiate a sell order: Enter the number of shares or dollar amount you want to sell in a stock or ETF and click continue. On the sell review screen, select “Estimated taxes owed” or “Estimated taxes saved” to see a detailed preview. Review the tax preview and use the information to decide if you want to move forward with the sale. When reviewing the estimated tax impact, you can see long-term and short-term capital gains along with any washed loss amount. These pieces of information can help you decide if moving forward with the sale is best for your tax situation. Tax impact preview with automated investing With Betterment’s automated investing portfolios, when you initiate a sale of securities (a withdrawal or allocation change), our algorithms first determine which ETFs to sell (rebalancing you in the process, by first selling the overweight components of your portfolio). Within each ETF, our lot selection algorithm, which we call TaxMin, is designed to select the most tax-efficient lots, selling losses first, and short-term gains last. To use Tax Impact Preview, you can select the option to view the estimated tax impact when you initiate an allocation change or withdrawal. This will give you detailed estimates of expected gains and/or losses, breaking them down by short and long-term. If your transaction results in a net gain, we estimate the maximum tax you might owe. And if it results in a loss, you could benefit from tax loss harvesting. Why is it “estimated tax impact”? The tax owed is an estimate because the precise tax owed depends on many circumstances specific to you, including your tax bracket and the presence of past and future capital gains or losses for the year across all of your investment accounts. We use the highest applicable rates, to give you an upper-bound estimate. The gains and losses are also estimates, as these depend on the exact price that the various ETFs and stocks will sell at. If the estimate is done after market close, the prices are sure to move a bit by the time the market opens. Even during the day, time will pass between the preview and the trades, and prices will shift, so it isn’t possible for the estimates to be 100% accurate to the outcome. Finally, while we are able to factor in wash sale implications from prior purchases in your Betterment account, the estimates could change substantially due to future purchases, and we do not factor in activity in non-Betterment accounts. That is why every number we show you, while useful, is an estimate. Tax Impact Preview is not tax advice, and you should consult a tax professional on how these estimates apply to your individual situation. Invest with transparency that puts you in control With Betterment’s Tax Impact Preview, you can finally see a fuller picture before you sell. Instead of being surprised by a tax bill months later, you’ll know your estimated short- and long-term gains upfront—helping you make smarter, more tax-efficient moves. Whether you invest on your own or through Betterment’s automated portfolios, Tax Impact Preview is designed to give you the clarity and confidence to stay on track toward your financial goals.
