The IRS will be sending out Letter 6419 in January of 2022 to let taxpayers know how much advance payments they received for the child tax credit. Please keep this letter with your tax records and bring it in during tax time so we can report this on the tax return. If you do not have this letter, the amount reported on the tax return may not be correct, which can result in: delayed processing of the return, lower refunds received, or more to pay in to the IRS.
