Following recent tax reforms, Montana simplified its system to two brackets: 4.7% for the first tier of taxable income and 5.9% for income exceeding a specific threshold (e.g., ~$20,000 for singles).
Montana does tax a portion of Social Security benefits, following federal guidelines, but offers specific state-level subtractions that can lower the taxable amount for many residents.
No. Currently, municipalities, cities, and counties in Montana (like Billings or Helena) do not impose a local income tax. Residents only pay the state-level tax.

Our calculator uses the most current Montana Department of Revenue tax tables. While it provides a highly reliable estimate for planning, it should not replace professional tax filing software.
