File Form 945-X — Adjusted Annual Return of Withheld Federal Income Tax or Claim for Refund

Correct a Form 945 you already filed. Each line takes the corrected total (column 1), what you originally reported (column 2), and the difference (column 3). Unlike the other amended 94x returns there is no fourth column: every line here is already a tax, so the difference is the correction.

Filing a year for the first time? That is Form 945.

$2 per filing — $1.50 each (filings 101–200), $1 each (filings 201+) once you file that many with us in a year. We e-file Form 945-X directly with the IRS.
