Understanding your letter 6419


What this letter is about

Letter 6419 includes:

  • Total amount of 2021 advance Child Tax Credit (CTC) payments
  • Number of qualifying children used to calculate advance payments, and repayment protection when filing your 2021 federal tax return 

To help taxpayers reconcile and receive 2021 CTC, the IRS is sending letter 6419, Advance Child Tax Credit Reconciliation from late December 2021 through January 2022. Taxpayers should keep this, and any other IRS letters about advance CTC payments, with their tax records.

Families who received advance payments must:

  • File a 2021 tax return
  • Compare the advance payments received in 2021 with the CTC amount they can claim for 2021

This letter contains helpful information for preparing tax returns. Taxpayers who received advance payments can also check amounts using the CTC Update Portal and Online Account on IRS.gov.

Eligible families who didn't receive advance child tax credit payments can claim the full amount of the child tax credit on their 2021 federal tax return. This includes families who don't normally need to file a tax return.
