Montana has two brackets: 4.7% on income up to approximately $20,500 and 5.9% above that. Montana has no sales tax, which partially offsets the income tax. The state offers a standard deduction of 20% of adjusted gross income (capped at a maximum amount). Montana does not impose local income taxes.
Regardless of state taxes, all Montana workers pay federal income tax using the 2026 brackets: 10% on the first $11,925 of taxable income (single), 12% up to $48,475, 22% up to $103,350, 24% up to $197,300, 32% up to $250,525, 35% up to $626,350, and 37% on income above that. The standard deduction is $15,000 for single filers and $30,000 for married filing jointly in 2026.
All workers in Montana pay Social Security tax at 6.2% on wages up to $176,100 (2026) and Medicare tax at 1.45% on all wages. An additional 0.9% Medicare surtax applies to wages over $200,000 for single filers. These federal payroll taxes apply uniformly regardless of which state you live in.
Pre-tax deductions reduce your taxable income for both federal and state purposes. Contributing to a 401(k) (up to $24,500 in 2026, plus $8,000 catch-up if 50+) lowers both your federal and MT state tax bill. Health Savings Account (HSA) contributions ($4,300 individual, $8,550 family in 2026) are also pre-tax. Review your W-4 withholding: if you receive a large refund each year, you may be overwithholding, which means less money in each paycheck. The Tax Bracket Calculator shows your federal marginal and effective rates.
