Filing Extensions for Military Service Members

If you’re serving in the U.S. military and cannot file or pay your Minnesota income tax by the due date (April 15 for most people), you can get an automatic extension. The exact rules depend on your duty status and where you’re stationed.

Note: If April 15 falls on a Saturday, Sunday, or holiday, we must receive your return and payment by the next business day.

You do not have to file a separate form to request an extension. If you file a joint return, your spouse also gets the extension. Penalties and interest apply if you do not file a return or pay your tax by the dates listed on this page.

What if I am Active Duty Military Personnel serving in a combat zone?

You may file and pay your Minnesota income tax 180 days after either of the following dates:

  • Your last day in a combat zone.
  • Your last day of continuous hospitalization for injuries suffered in a combat zone.

When you file your Minnesota return, write "Serving in a combat zone” on a separate sheet of paper and enclose it with Form M1, Individual Income Tax.

What if I am Active Duty Military Personnel not serving in a combat zone?

You have until Oct. 15 to file your state tax return.
 
To avoid a late payment penalty, you must pay at least 90 percent of your Minnesota income tax by April 15. You must then pay any remaining tax when you file your return or by Oct. 15 (whichever is earlier).
 

What if I am a Reservist or National Guard Member called to active service?

Your extended deadline to file and pay your Minnesota income tax varies, as outlined below:
 
If you're serving Then
​In a combat zone ​You get the same extension as active duty personnel serving in a combat zone.
​In the U.S. ​You have until Oct. 15 to file and pay your Minnesota tax without penalty.
​Outside the U.S. but not in a combat zone ​You have 180 days after you return from abroad.
When you file your Minnesota return, write “Filing under a military extension” on a separate sheet of paper and enclose it with Form M1, Individual Income Tax.
