How to File a Utah Tax Amendment

If you need to change or amend an accepted Utah State Income Tax Return for the current or previous Tax Year you need to complete Form TC-40. Form TC-40 is a Form used for the Tax Return and Tax Amendment. You can prepare a current tax year Utah Tax Amendment on eFile.com, however you can not submit it electronically. If you need to file a federal amendment, 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 Utah Tax Agency, thus you should file a Utah Tax Amendment within one year.
