How to File an Oregon Amended Tax Tax Return

If you need to change or amend an accepted Oregon State Income Tax Return for the current or previous Tax Year, you need to complete Form 40 (residents), Form 40-N (nonresidents), or Form 40-P (part-year residents). Forms 40, 40-N, and 40-P are Forms used for the Tax Amendment. You can prepare a 2022 Oregon Tax Amendment on eFile.com, however you cannot submit it electronically. In comparison, the IRS requires a different Form - Form 1040X - to amend an IRS return (do not use Form 1040 for an IRS Amendment).

The IRS might send you a notification to change an error on your Return, or you might have discovered an error. If you or the IRS amended or changed one of your IRS Tax Return(s), the IRS will report this to the Oregon Tax Agency, thus you should file an Oregon Amendment within one year.
