Form 945‑X is the Adjusted Return of Withheld Federal Income Tax used by businesses to correct errors on a previously filed Form 945. Whether you under‑reported, over‑reported, or need to claim a refund, the fillable PDF version lets you make adjustments quickly and accurately.
The IRS requires a separate Form 945‑X for each calendar year you need to correct. The form consists of four parts: selecting the correction process, detailing the corrections, providing a written explanation, and signing the return. It must be completed in full—both pages—and cannot be attached to the original Form 945.
Instead of downloading the PDF and editing it in a separate program, simply click the "Fill out this form" button on our page. The Formize PDF Filler app will load in your browser, allowing you to type directly into each field, save your progress, and export a completed PDF ready for submission.
You can download the official, up‑to‑date Form 945‑X PDF directly from the IRS website. Our page links to the same file so you always have the correct version.
