Understanding ACTC Letter 6419

What is the ACTC Letter 6419?

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

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.

Recent ACTC Updates 2/01/2022

The IRS is sending letters to millions of parents who received the advanced Child Tax Credit payments last year, urging people to refer to those forms — letter 6419 — when filling out their tax returns. But on Monday, the agency warned that some of those letters may include incorrect information.

The erroneous information could have a severe impact on some families' finances, given that the IRS is advising taxpayers to take extra care this year that their tax returns are accurate. The agency is still digging out of a backlog of 6 million individual returns filed in 2021 — many of those were flagged for review because of mistakes taxpayers made in reporting how much they received in government stimulus payments or other tax credits.

The potentially erroneous letters could add to what IRS Commissioner Chuck Rettig warned may be "a very frustrating filing season" for taxpayers and tax preparers. He also encourages taxpayers to follow these tips to ensure smooth processing of their returns:

  1. File electronically.
  2. File as quickly as possible after the IRS starts accepting tax returns on January 24.
  3. Request direct deposit.

"If taxpayers need a refund quickly, we are urging them to not file on paper," Rettig said.

Filing an inaccurate return — such as by guessing how much you received from the advanced CTC payments — could "create an expensive delay," he added.

If taxpayers heed that advice and there are no red flags on their tax return, they should receive their refund within 21 days, according to the IRS. Asked how long it could take to get a refund if, say, someone files on paper or has a mistake in their returns, Corbin said, "Right now we aren't really sure."

Reporting accurate data about the advanced CTC payments is important because the enhanced tax credit was paid half in advance, with the other half to be paid through taxpayers' refunds after they file their 2021 tax return.
