Montana: take-home, federal, state & FICA
Calculation parameters: Single filer, standard deductions, zero additional withholdings, $75,000 annual salary, 24 pay periods. Models incorporate the updated 2026 withholding adjustments and wage bases published by the Montana Department of Revenue.
The Montana Department of Revenue enforces a simplified income tax structure. Following major legislative overhauls, the state compressed its complex multi-tier brackets down to just two primary tax rates: a lower rate of 4.7% and a top marginal rate that drops to 5.65% effective January 1, 2026.
For a single filer earning $75,000, taxable income is assessed across these streamlined tiers, generating an estimated annual state tax liability of approximately $3,325. Employees must complete the state's Form MW-4 to configure their withholding preferences and personal exemptions.
While Montana does not levy a statewide general sales tax, it maintains a unique payroll requirement: it is one of the very few states that legally mandates an employee-side tax for State Unemployment Insurance (SUI).
Administered by the Montana Department of Labor and Industry, this employee SUI tax requires a fractional percentage deduction from gross wages up to an annually adjusted taxable wage base. For a $75,000 earner, this deduction results in a steady payroll reduction (typically around $248 annually, or $10.35 per semi-monthly check) until the annual wage cap is exhausted.
Montana explicitly prohibits cities, towns, and counties (such as Missoula, Bozeman, or Billings) from levying local income taxes or municipal payroll head taxes on individual wages.
For supplemental wages—including performance bonuses, commissions, or severance packages—Montana allows employers to calculate withholding either by aggregating the supplemental pay with regular wages or by applying a flat percentage rate consistent with the state's top marginal tax bracket.
2 marginal single-filer bands for 2025, running from 4.7% to 5.9% and applied to income after the $15,000 standard deduction. A $75,000 earner reaches band 2 of 2; only income above $20,500 ever meets the top rate.

That $3,029 a year — about $252 a month — is what Montana's income tax costs against a state that charges none. On this salary it ranks 17th of 51 by state income tax paid, just behind Connecticut at 4.17%.
Take-home pay is gross salary minus five separate withholdings, each with its own rule and its own base. Two are federal and fixed nationwide, two are FICA payroll taxes with their own ceilings, and one is set by Montana. Montana uses a progressive schedule of 2 brackets topping out at 5.9%. On $117,000 the state collects $5,358 — an effective 4.58% of gross, not the headline 5.9%, because only the slice of income sitting inside each bracket is taxed at that bracket's rate. At $117,000 this example sits 2 brackets into the 2-bracket schedule, giving a marginal rate of 5.9% on the next dollar earned against an average of 4.58%. That gap between marginal and average is the number that matters when weighing a raise, a bonus or a larger 401(k) deferral — each is priced at the marginal rate, not the average. Note also that the 401(k) contribution comes out before federal income tax is computed but not before Social Security and Medicare — a detail that trips up most hand calculations.
Take-home = Gross − 401(k) − Federal income tax − Social Security − Medicare − State taxFederal = brackets applied to (gross − 401(k) − $15,000 standard deduction)State income tax = sum over brackets of (income in bracket × bracket rate), up to 5.9%where:
Assumptions: Single filer, standard deduction, 6% traditional 401(k), no other pre-tax benefits, credits or local income tax. Health premiums, HSA contributions and city taxes (where they exist) would each change the result. 2026 federal figures.
Rather than a round number, this example uses the salary Montana's own housing costs imply: a median-priced $450,000 home carries a $2,729 monthly payment, and the 28% front-end ratio lenders underwrite to puts that within reach at about $117,000 a year. Here is where that salary actually goes for a single filer contributing 6% to a traditional 401(k).
Result$79,862 a year — $6,655 a month, $3,072 per biweekly cheque
Total tax burden is $30,118, an effective 25.7% of gross — of which Montana takes 4.58%. The $7,020 401(k) deferral is not a tax; it is still your money.
