Montana taxes wages on a graduated schedule that tops out at 5.65%, a top rate that was cut for 2026 and is scheduled to fall again. Montana starts from federal taxable income and uses the federal standard deduction, and a recent reform removed both the old state personal exemptions and the deduction for federal taxes paid. Income moves from a lower rate to the 5.65% rate at a single threshold. There are no employee-paid disability or paid-leave premiums in Montana and no local income taxes on wages. This page serves Montana workers comparing take-home; the tables below show pay across salary levels for 2026 after federal tax, FICA and Montana income tax.

Frequently asked questions
How is take-home pay calculated in Montana?
We start with your gross salary and subtract the 2026 federal standard deduction for your filing status, then apply the federal tax brackets to what is left. FICA, the Social Security and Medicare tax, is added on the gross. On top of that comes the Montana state layer, using Montana's own brackets or flat rate and its deductions. The result is your estimated annual tax liability, which we divide across your pay periods to show weekly, biweekly, and monthly figures.
Does Montana tax bonuses differently?
A bonus is withheld using supplemental wage rules, which can differ from your regular paycheck. See the Montana bonus tax page for how the federal flat rate and the state layer apply.
Are these numbers withholding or final tax?
These are an annual tax-liability estimate, not the exact withholding from any one paycheck. The per-paycheck columns are the annual figure divided by the number of pay periods. Your employer's real withholding uses IRS payroll tables and can differ slightly, then reconciles when you file your return.
