Hello April:
The Montana Department of Revenue has two categories for Tribal members. Income is exempt from Montana income tax if all of the following requirements are met:
- You are an enrolled tribal member of the governing tribe of a reservation;
- You resided and worked on that reservation; and
- You earned income by working on that reservation.
If the three conditions above are met, no tax return is needed. Send in this form by mail.
Here is a link: https://mtrevenue.gov/wp-content/uploads/dlm_uploads/2023/03/ETM_2022.pdf
If money was earned off the reservation and meets the income threshold, a Montana income tax return will be required. The details of who needs to file a form are under the instructions for Line 2 in the above form.
Have an amazing day. Evelyn M (CPA 20+ years)
