The 1099-DIV reflects dividend payments received and capital gains distributions from stocks you own.
You will receive one by Feb. 16, 2021, if you had a Betterment taxable account and:
You received more than $10 in dividends in 2020, or
You paid any foreign or federal taxes within your account
Please note that while Betterment is not required to issue you a 1099 if you earned a relatively small amount of income from your account, taxpayers are still required under IRS rules to report and pay taxes on any earned income.
