Tax filing season will soon be here, and as investors, it’s important to be aware of the many annual deadlines and tax documentation release dates that could affect how and when you file your taxes.

While tax season is often thought of as stressful, annoying, and time-consuming, the reality is that this is a part of the year when the choices and plans you make can greatly affect your future financial outcomes. In general, it’s safest to file your taxes as soon as your forms are available, and to review your financial plan after you’ve filed to make sure you’re planning as tax-efficiently as possible.

Before you start preparing to file your 2018 taxes, take a look at our 2018 tax season calendar to make sure you’re aware of some important tax deadlines. If you don’t find what you’re looking for here, you can also check out—the final source for all taxes-related dates, rules, and regulations.

2018 Tax Season Calendar

Deadline Why It’s Important
Dec. 28, 2018

11:59 p.m. EST

The end of 2018 marks an important deadline for making big, strategic moves that can help shape your taxable income for the year. Charitable gifts and Roth IRA conversions are two big examples. Read up on what tax planning changes may be worth your while before December 28.If you’re taking withdrawals from your retirement accounts, December 28 at 11:59 p.m. EST  is also your deadline for requesting a withdrawal from Betterment.
Jan. 31, 2019 Thursday, January 31, is the deadline for Betterment to send out the Form 1099-R  which is commonly received for distributions, conversions, and rollovers (except direct IRA to IRA transfers) from retirement accounts. If you are lucky enough to get a qualified tax-free Roth distribution, you can now officially celebrate by singing a 1980’s song (“Don’t You (Forget About Me)” is a classic).
Feb. 15, 2019 Friday, February 15, is the deadline for Betterment to send out the Form 1099-B/DIV, which is commonly received for investment sales and dividends received. You will not receive forms 1099-B or 1099-DIV for investments held in retirement accounts.
Friday, February 15, is the day that you can import your tax information into commercial tax software (e.g. TurboTax).
Mar. 15, 2019 Friday, March 15 is the last day that you use FSA funds from your 2018 contributions.
Apr. 12, 2019

10 p.m. EST

Friday, April 12 at 10 p.m. EST, is the last day you can make a Betterment Traditional IRA or Roth IRA contribution  and have it count for 2018. In addition, this is the first deadline for recharacterization of IRA contributions.
Apr. 15, 2019 Monday, April 15, is the last day to file your taxes with the IRS (unless you request an extension). Handle any of your last minute moves the week before, just to be sure.
May 31, 2019 Friday, May 31, is the deadline for Betterment to send out the Form 5498  which is commonly received for IRA contributions, conversions, and rollovers from retirement accounts. While this form is important to support IRA basis and rollovers if ever audited, it is not needed to file a tax return by April 15.
Oct. 15, 2019 Tuesday, October 15, is the deadline for individuals to file their tax if they filed for an extension. It should be noted that filing for an extension is not an extension to pay as interest/underpayment penalties may still apply. In addition, this is the second deadline for recharacterization of IRA contributions for individuals on extension or amending their timely filed tax return.


Visit our 2018 Tax Filing Support Guide for more information about preparing for tax time at Betterment, and visit for more tax information. This tax calendar is by no means exhaustive, but we hope having important dates in one place will be helpful.

Of course, even if you’re aware of these dates and get your tax forms in order, it might still be useful to consult a tax advisor to get personalized help. While Betterment is a financial advisor, we are not a tax advisor, so this tax calendar and article should not be considered tax advice—it’s just informational.
