I got Letter 6475 or 1444-C from the IRS. What is it?
Letter 6475 and 1444-C are letters the IRS sent to everyone who received the third stimulus check (Economic Impact Payment), which was issued starting in March 2021. The letters contain information about how much the IRS issued you in the third stimulus check.
If you have not yet filed your 2021 return, accurately reporting how much you received in stimulus checks can help you and your tax preparer correctly claim any missing money—so these letters can be very helpful. Letter 1444-C would have been sent around the time your payment was issued in March 2021. Letter 6475 was sent in January 2022.
