Michigan State Tax Extensions: Business, Personal, Information and Nonprofit Tax Returns

Income Tax (Individual and Fiduciary)

File Form 4 or a copy of your federal extension. An extension of time to file the federal return automatically extends the time to file the Michigan return to the new federal due date. An extension of time to file is not an extension of time to pay. If you have not been granted a federal extension, the Michigan Department of Treasury (Treasury) will grant a 180-day extension for individual income tax and composite returns, or a 150-day extension for fiduciary returns.

• Do not file this form if a refund is expected or if you are not submitting payment with this form.
• If, at the time the extension is filed, it is determined additional Michigan tax is due, send the amount due and a completed Form 4 or a copy of your federal extension form. If filing Form 4, do not send a copy of the federal extension to Treasury. Retain a copy for your records. Extension requests received without payment on the account will not be honored and penalty and interest will accrue on the unpaid tax from the original due date of the return.
• Payments made to date include withholding, estimated tax payments, a credit forward from the previous tax year, and any other payments previously made for this tax year. Individual income tax filers should include any Michigan withholding.

Do I need to file for Michigan State Extension exclusively to get the time for state extension?

United States military personnel serving in a combat zone on April 15, 2025, will be given 180 days after leaving the combat zone to file their federal and State tax returns and will be exempt from penalties and interest. When e-filing, service men and women serving in combat zones should enter the words "Combat Zone" in the preparer notes.

To request more time to file your Michigan tax return, send a payment of your estimated tax to Treasury with a copy of your federal extension (U.S. Form 4868) on or before the original due date of your return. Treasury will extend the due date to your new federal due date. If you do not have a federal extension, file an Application for Extension of Time to File Michigan Tax Returns (Form 4) with your payment. Treasury will not notify you of approval. Do not file an extension if you will be claiming a refund.

Do I get more time to pay my returns on being granted with extension of time to file my returns?

No. An extension of time to file is NOT an extension of time to pay. If you do not pay enough with your extension request, you must pay interest on the unpaid amount. Compute interest from the original due date of the return. Interest is 1 percent above the prime rate and is adjusted on July 1 and January 1.
You may be charged a penalty of 10 percent or more if the balance due is not paid with your extension request.When you file your MI-1040, include on line 30 the amount of tax you paid with your extension request. Attach a copy of your federal or state extension to your return.
When you file your MI-1040, the amount of tax you paid with your extension request. Attach a copy of your federal or state extension to your return.
