How Montana taxes wages
Montana has a two-bracket income tax for 2026: 4.7% up to $47,500 of taxable income for single filers ($95,000 married filing jointly, $71,250 head of household), and 5.65% above that. Notably, Montana has no state sales tax — one of only five states without one — though a few resort communities levy a small local resort tax (up to 3%) on certain goods and services. For most purchases, from groceries to electronics, no sales tax applies. Property taxes are moderate. The combination of income tax without sales tax creates a different financial dynamic than most states.
Montana starts from your federal taxable income — the figure left after the federal standard deduction. Anything that lowers federal taxable income therefore also lowers Montana tax.
Montana is one of only five states with no sales tax, and Bozeman has become one of the fastest-growing small cities in America, attracting a wave of tech workers and remote employees drawn by the state's natural beauty and tax advantages.

401(k) contributions and Montana tax
Because Montana starts from a federal income figure, traditional 401(k) deferrals that lower federal wages also lower the Montana base. Roth contributions do not. Health-account treatment can differ by state and is not assumed here.

Montana State Tax FAQ (2026)
Data Sources & Methodology
- • Federal tax brackets: IRS Revenue Procedure 2025-32 (2026 tax year)
- • Standard deduction: $16,100 (single), $32,200 (married filing jointly)
- • Social Security: 6.2% on wages up to $184,500 (SSA 2026)
- • Medicare: 1.45% on all wages + 0.9% additional above $200,000
- • Work hours: 40 hours/week × 52 weeks = 2,080 hours/year (standard full-time)
- • Federal income tax: Estimated annual federal income tax for 2026 (IRS Revenue Procedure 2025-32 brackets), spread evenly across paychecks — an annual tax estimate, not an employer withholding simulation
- • State taxes: Verified annual state income tax is calculated without additional state inputs across four filing statuses and nine tested wage levels ($15,000–$500,000) in 28 of the 51 jurisdictions (50 states + DC). 21 have partial, input-dependent or estimate-only coverage — Alabama (lower incomes), Arkansas (lower incomes), Arizona (estimates; not fully verified), California (estimates; not fully verified), Delaware (lower incomes), Iowa (lower incomes), Kentucky (lower incomes), Massachusetts (lower incomes), Maryland (lower incomes), Minnesota (married jointly), Missouri (joint returns need each spouse’s wages), Mississippi (joint returns need each spouse’s wages), North Dakota (married jointly), New Mexico (head of household), New York (married jointly at lower incomes; married separately at lower incomes; head of household at lower incomes), Ohio (joint returns need each spouse’s wages), Oregon (estimates; not fully verified), Pennsylvania (lower incomes), Utah (estimates; not fully verified), Virginia (lower incomes) and West Virginia (single at lower incomes; married jointly at lower incomes; head of household). Idaho and Vermont show "Not calculated" until their 2026 rules are published and verified. Missing rules or required inputs show "Not calculated"; estimates are labelled. Joint returns needing each spouse’s wages use an empty input, never an assumed split. This measures wage-only scenarios, not all tax situations. Employee-paid payroll taxes are included where they apply, such as CA SDI (1.3%, uncapped), NY PFL (0.432%, $411.91 max) and NJ TDI/FLI (2026 $171,100 base)
- • Coverage: Federal, state and state payroll taxes only — city, county and school-district income taxes (e.g. NYC, Ohio municipalities, PA EIT, Maryland counties) are not included
- • Estimates assume single filer, no dependents, standard deduction, no pre-tax deductions unless specified
