FAQ
Montana-specific questions
I left Montana for Dubai — am I still a Montana resident for tax?
Montana taxes residents on worldwide income; residency generally follows domicile, which continues until you clearly establish one elsewhere — keep evidence of your UAE ties. We run a residency review as the first step of every Montana engagement, so your state position is deliberate, not accidental.
What does the Montana return involve alongside my federal filing?
Your departure year usually means a part-year resident return; Montana-source income (rentals, local business income) can remain taxable after you leave. The state return is an add-on to your federal engagement, quoted after the residency review.
Montana + federal, one desk.
One call reviews your residency position and quotes both returns — fixed, in writing.
