There are several reasons you may need to file your tax return after the normal due date.
Your unique tax situation will determine what that means for you. A qualified tax professional can help you find the information that best fits your situation.
Automatic Six-Month Extension
You receive an automatic six-month extension to file your individual income tax return.
You do not need to submit a form for the extension.
You may make an extension payment:
- Through our TransAction Portal (TAP),
- With Income Tax Express, or
- Using the Montana Individual Income Tax Payment Voucher (Form IT)
Military Active Duty Extension
If you or your spouse is:
- On active duty in the regular armed forces, and
- Serving in a combat zone or contingency operation
You can extend your due date up to 180 days from your last day in a combat zone.
When you file your return, write “Combat zone or contingency operations extension” in red ink at the top of your Montana Individual Income Tax Return Long Form (Form 2).
If you file within 180 days of your last day in a combat zone, you won’t be charged any penalties or interest.
Penalties and Interest
Individual Income Tax is subject to uniform penalties and interest.
