What the calculator does
For each gross annual salary, it estimates federal income-tax liability, FICA (6.2% Social Security up to the $184,500 wage cap + 1.45% Medicare), then Montana income-tax liability using the brackets above. Pre-tax deductions reduce the modeled taxable income.
Scope: this is an annual planning estimate, not a payroll-withholding calculation. It does not model W-4 or state withholding elections, tax credits, itemized deductions, most local taxes, or employer-specific benefits.

FAQ
How is take-home pay in Montana calculated?
Take-home = gross salary − federal income tax − FICA (Social Security + Medicare) − Montana state income tax. This 2026 planning estimate uses the brackets and rates documented above. State thresholds may be from an earlier tax year; check the year labels and linked sources above.
What are Montana's income tax brackets?
Montana has 2 brackets ranging from 4.7% on the first dollars to 5.65% on the top dollars. Only the dollars in each band are taxed at that band's rate — a higher bracket doesn't mean your whole income gets the higher rate.
Anything special about Montana taxes I should know?
Montana simplified to 2 brackets; top rate trimmed from 5.9% to 5.65%.
What about local city or county taxes in Montana?
Montana doesn't have widespread local income taxes for most workers, so the calculator above covers the main paycheck deductions. If you live in a city with a local income tax, add that separately.
Are these 2026 numbers accurate?
