IRS warns some taxpayers may have received incorrect Child Tax Credit letter

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.
