Frequently Asked Questions: Montana Paycheck Taxes
1. What is the Montana state income tax rate in 2026?

2. Do Billings residents pay a city income tax?
No. Unlike New York City, Philadelphia, or Detroit, Billings does not levy an additional local municipal income tax on employees. You only pay federal income tax, FICA, and Montana state tax.
3. Does Montana have state disability insurance (SDI) tax?
No. Unlike California, New Jersey, or New York, Montana does not have a mandatory state disability insurance (SDI) deduction taken from your paycheck.
