How to Prepare, File A Michigan Tax Amendment

If you need to change or amend an accepted Michigan State Income Tax Return for the current or previous Tax Year, you need to complete Form MI-1040 AND Schedule AMD (amended return changes schedule). You can update this form for the current tax year in your account.

You can prepare a current Michigan Tax Amendment on, however you cannot submit it electronically. Simple check off the box in the upper right and indicate that this is a state tax amendment. 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 Michigan Tax Agency, thus you should file a Michigan Amendment within one year.
