How Montana State Income Tax Works

Montana has a progressive income tax system with two tax brackets for 2026 under HB337, which reduced rates from the previous 5.9% top rate. The rates apply to your Montana taxable income, which uses the same federal standard deduction.

4.7% on taxable income up to $47,500 for single filers and married filing separately, $95,000 for married couples filing jointly, and $71,250 for heads of household
5.65% on taxable income over those thresholds

Montana does not offer a separate state standard deduction. Instead, it uses the federal standard deduction amounts ($16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household in 2026). Montana also does not offer a personal exemption.

Federal Tax and FICA Deductions

Your paycheck also includes federal income tax and FICA (Social Security and Medicare) deductions. The 2026 federal income tax brackets range from 10% to 37% based on your taxable income and filing status. The standard federal deduction for 2026 is $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household.

FICA taxes include 6.2% for Social Security (up to the annual wage base of $184,500), 1.45% for Medicare, and an additional 0.9% Medicare surtax on earnings over $200,000 for single filers or $250,000 for married couples filing jointly.

Pre-Tax Deductions

Contributions to a traditional 401(k), Health Savings Account (HSA), and pre-tax health insurance premiums reduce your taxable income, lowering both your federal and state tax liability. This calculator accounts for these deductions to give you a more accurate estimate of your take-home pay.
