IRS will be issuing letter 6419 for total “Advanced Child Tax Credit” received for the 2021 tax year. This letter is required when filing your taxes.
Unlike the stimulus payments issued in 2020 and 2021, the advance payments of the child tax credit must be reconciled on the 2021 return. If you were not eligible for the credit in 2021, the advance payments will need to be repaid with the 2021 return. In January, the IRS will be mailing out Letter 6419 showing the total amount of advance payments your received. This letter will be needed to prepare your 2021 returns.
You have the ability to stop advance payments, or make changes to your banking information within the Child Tax Credit Update Portal. In order to do so, you must unenroll or make changes 3 days before the first Thursday of next month by 11:59 p.m. Eastern Time. You do not need to unenroll each month.
