Questions & Answers

How do I file a Michigan Extension?

You only need to file a Michigan state extension if you expect to owe taxes to the state of Michigan. If you'll be getting a refund, you don't need to file a Michigan extension.

If you will owe taxes and want to request more time to file your Michigan tax return, send a payment of your remaining estimated tax to the Michigan Department of Treasury with a copy of your approved federal extension (U.S. Form 4868) on or before the original due date of your return.

If you don't have a federal extension, file an Application for Extension of Time to File Michigan Tax Returns (Form 4  ) with your payment.

Detroit Returns: Detroit extensions are not required if you're expecting a Detroit refund. If you need to file a Detroit extension, file an Application for Extension of Time to File Michigan City Tax Returns (Form 5209  ) and submit it to the Michigan Department of Treasury with your city tax payment.

Other Michigan Cities: If you need to file any other Michigan city extension, you'll need to fill out a form from your city's website and submit it to the city with your city tax payment.
