In the IRS Issue Number: IR-2021-76, the IRS indicated some of the reason why taxpayers might have received Recovery Rebate Credits (If you did not receive stimulus money and you were entitled to it, the Recovery Rebate is calculated when you file your 2020 tax return).

Some of the reasons highlighted by the IRS are:

  • The individual was claimed as a dependent on another person’s 2020 tax return.
  • The individual did not provide a Social Security number valid for employment.
  • The qualifying child was age 17 or older on Jan. 1, 2020.
  • Math errors relating to calculating adjusted gross income and any EIPs already received.
