The recovery rebate credit is a refundable tax credit that can be claimed on your 2021 return if you did not receive your third stimulus check or received the wrong amount.
If for some reason the Economic Impact Payment was not received in 2020 or 2021, the Recovery Rebate Credit permitted some taxpayers to reduce their taxes by claiming a credit for the full Economic Impact Payment.
The base credit amount for most persons in 2021 is $1,400. The starting amount for married couples filing jointly with taxes is $2,800. For each dependant included on your 2021 tax return, you must add $1,400.
The calculation of the recovery rebate credit is basically the same as the calculation of the third-round stimulus checks, with the exception that they are based on data from various sources.
