Montana Payroll Tax Overview
Montana uses a graduated state income tax system with a top marginal rate of 5.9%. Lower income levels are taxed at lower rates, so your effective state tax rate will be below the 5.9% top bracket. Workers in Montana pay state income tax on top of federal income tax (10%–37%), Social Security (6.2%), and Medicare (1.45%).
The 2026 federal income tax brackets for single filers: 10% on the first $11,925; 12% to $48,475; 22% to $103,350; 24% to $197,300; 32% to $250,525; 35% to $626,350; 37% above. Pre-tax deductions (401k, health insurance, HSA) reduce your taxable income before both federal and state taxes are applied.
This calculator estimates your Montana state tax using your gross pay and the top-bracket rate as a conservative estimate. For a precise calculation, use Montana's official tax brackets and apply the graduated rates to your taxable income after standard deductions.
Federal vs Montana Tax Burden
For a Montana single filer earning $60,000 annually, estimated federal income tax is roughly $6,748 (11.2% effective rate), plus Montana state income tax of approximately $2,480 (estimated effective rate), Social Security $3,720, and Medicare $870. Estimated annual take-home: around $46,200.
States with graduated income tax rates like Montana apply higher rates only to income above each threshold — similar to how federal tax brackets work. Your effective state tax rate will be lower than the top 5.9% marginal rate unless nearly all your income falls in the top bracket.
To reduce your Montana paycheck tax burden, maximize pre-tax deductions: 401(k) contributions (up to $23,500 in 2026), HSA contributions (up to $4,300 for self-only coverage), and employer-sponsored health insurance premiums all lower both federal and state taxable income.
How to Use This Montana Paycheck Calculator
Enter your pay period (weekly, biweekly, semimonthly, monthly, or annual), then input either your annual gross salary or your hourly rate and average hours per week. Select your federal filing status — single, married filing jointly, married filing separately, or head of household — as this determines your federal tax brackets and standard deduction.
If you have pre-tax deductions such as a 401(k) contribution, health insurance premium, or HSA contribution, enter the total per-period dollar amount. These reduce your taxable income before federal and state taxes are calculated. The calculator will show federal income tax, Social Security (6.2%), Medicare (1.45%), an estimated Montana state income tax, your total deductions, and your net take-home pay — both per period and annualized. The Montana line is an effective-rate estimate rather than a bracket-by-bracket computation, so it will sit slightly above the exact figure; use the two-bracket table further down this page when you need the precise number.
Results are estimates based on standard assumptions and 2026 tax rates. Actual withholding may differ based on your W-4 elections, additional withholding, local taxes (in some cities), or retirement plan contribution limits. For precise payroll calculations, consult your payroll provider or a tax professional.
Montana 2026 State Tax Brackets & SB 121 Reform
Per the Montana Department of Revenue (mtrevenue.gov), Montana simplified its tax structure under Senate Bill 121 (signed 2023, effective 2024 onward) into just two brackets that scale with filing status. For single filers in 2026: 4.7% on Montana taxable income up to approximately $21,100; 5.9% on income above that threshold. For married-filing-jointly: 4.7% up to ~$42,200, then 5.9%. Montana also uses federal taxable income as the starting point for its state return (rather than the older Montana standard deduction system), so federal pre-tax deductions like 401(k), HSA, and traditional IRA flow straight into Montana state tax savings. Note: Montana has NO state sales tax — payroll is the main state tax burden. Updated 2026-07-09.
Paycheck Calculator Montana — No Sales Tax Impact on Real Take-Home
Montana is one of only five US states with no general sales tax (with Alaska, Delaware, New Hampshire, Oregon). This changes the "effective take-home" math versus states with income tax alone: a Montana worker paying 5.9% state income tax but 0% sales tax spends dollars more efficiently than a Washington or Tennessee worker paying 0% state income tax but 8.5-9.5% combined state+local sales tax. On a $60,000 household with $32,000 of taxable purchases per year, Montana's zero sales tax saves roughly $2,720 that a Washington household loses to sales tax — enough to offset most of Montana's income tax bite. Per Montana DoR, this is why per-capita net take-home in Bozeman, Missoula, and Billings is competitive with Seattle and Nashville despite the headline income-tax gap. Resort taxes (up to 3% in Whitefish, Big Sky, West Yellowstone) apply only to specific tourism goods — not general grocery/apparel/utilities.

2026 Montana Paycheck Calculator: Worked Examples by Salary
This Montana paycheck calculator uses 2026 IRS federal brackets (IRS Publication 15-T) plus Montana's two-bracket state structure (4.7% / 5.9%). Salary $50,000 single, biweekly, $0 pre-tax → standard deduction $15,000 → taxable $35,000 → federal $4,008 + MT state $1,818 (4.7% on first $21,100 = $992 + 5.9% on $13,900 = $820) + Social Security $3,100 + Medicare $725 = $9,651 → net $40,349/year or $1,552/biweekly. Salary $80,000 single example: taxable $65,000 → federal $7,648 + MT state ~$3,584 + SS $4,960 + Medicare $1,160 = $17,352 → net $62,648/year or $2,410/biweekly. Hourly $20/hr × 40 × 52 = $41,600 → standard deduction $15,000 → taxable $26,600 → federal $2,769 + MT state ~$1,309 + SS $2,579 + Medicare $603 = $7,260 → net $34,340/year or $660/week. Adding 6% to 401(k) on $80,000 saves ~$396 federal + ~$283 Montana state tax annually.
Montana Remote-Worker & Multi-State Tax Nexus Rules
Montana attracted an estimated 30,000+ net remote workers between 2020 and 2026 per Montana Department of Revenue filings — many keeping employment ties to Washington, California, or Texas employers. For Montana paycheck calculator users in that situation, three rules matter. First, a full-year Montana resident owes Montana tax on 100% of worldwide W-2 wages regardless of where the employer is headquartered — the employer's state doesn't affect Montana's claim. Second, if the out-of-state employer is not registered with Montana DoR for withholding, your paycheck arrives with zero Montana withholding, meaning you owe the full 4.7%/5.9% Montana tax at April filing plus quarterly estimated taxes if the balance exceeds $500. Third, if any workday is physically performed inside a source state (Washington business trip, California client visit), that state may claim nonresident withholding on those days — Montana then offers a credit for taxes paid to other states. The clean setup: quarterly estimated Montana payments (Form MT-EST) matching the paycheck calculator's estimate, keeping the balance due at filing under $500 to avoid underpayment penalty.

Montana Paycheck vs Neighboring States — WY, ID, ND at $75K
Montana workers considering a move across the border can compare take-home in seconds. For a $75,000 single filer with the 2026 federal standard deduction ($15,000) and $0 pre-tax deductions: Montana → federal $6,748 + MT state ~$3,171 + FICA $5,738 = $60,343 take-home. Wyoming (no state income tax) → $63,514 (+$3,171 vs MT). Idaho (5.695% flat 2026 per Idaho State Tax Commission) → federal $6,748 + ID state ~$3,417 + FICA $5,738 = $60,097 (-$246 vs MT). North Dakota (1.95%/2.5% brackets 2026 per ND Tax Commissioner) → federal $6,748 + ND state ~$1,238 + FICA $5,738 = $62,276 (+$1,933 vs MT). Wyoming is the biggest paycheck winner in the region, but Montana ties Idaho closely and beats every high-tax coastal state by $3,000-$8,000 per year on the same $75K.

Montana State Tax by Taxable Income — Exact Two-Bracket Table
Montana tax is not a flat percentage of your salary, and that is where most online estimates drift. The two brackets apply to Montana taxable income — the figure after your federal standard or itemised deduction, not gross pay — so the arithmetic is: 4.7% on the first $21,100 (single) or $42,200 (married filing jointly), then 5.9% on everything above. The table below is computed directly from that rule, so you can check any payroll estimate against it in a few seconds. Thresholds are published by the Montana Department of Revenue and are indexed annually under SB 121.
| MT taxable income | Tax (single) | Effective rate |
|---|---|---|
| $20,000 | $940 | 4.70% |
| $30,000 | $1,517 | 5.06% |
| $40,000 | $2,107 | 5.27% |
| $50,000 | $2,697 | 5.39% |
| $75,000 | $4,172 | 5.56% |
| $100,000 | $5,647 | 5.65% |
Notice the effective rate never reaches 5.9% — it only approaches it, because the first $21,100 is always taxed at 4.7%. Married filing jointly pays the lower rate on twice as much income, so a joint return on $50,000 of taxable income owes $2,444 rather than $2,697. Updated 2026-08-31.
Frequently Asked Questions
Does Montana have state income tax?
Yes. Montana has a two-bracket state income tax: 4.7% on lower income and 5.9% on income above the upper threshold (~$21,100 single / ~$42,200 married filing jointly in 2026). Source: Montana Department of Revenue.
What is the Montana state income tax rate?
Montana's top state income tax rate is 5.9% in 2026. The lower bracket is 4.7% on income up to about $21,100 (single) or $42,200 (MFJ). The state simplified to this two-bracket structure under SB 121, effective 2024 onward.
How is take-home pay calculated in Montana?
Take-home pay in Montana is your gross pay minus federal income tax (10%–37%), Social Security (6.2%), Medicare (1.45%), Montana state income tax (4.7% or 5.9%), and any pre-tax deductions like 401(k) or health insurance.
What payroll taxes apply in Montana?
Employees in Montana pay federal income tax, FICA (Social Security 6.2% + Medicare 1.45%), and Montana state income tax (4.7% / 5.9%). There is NO state sales tax in Montana. Employers match the FICA portion.
Does Montana have SDI or disability tax?
Montana does not have a state SDI or disability insurance payroll tax deduction. Workers' compensation is funded by employers, not via paycheck deduction.
Is this Montana paycheck calculator free?
Yes — fully free, no sign-up, no data leaves your browser. The calculator uses 2026 federal brackets and the Montana two-bracket system, so the numbers match what your employer's payroll software will produce within a small margin (it does not capture every W-4 election like additional withholding amounts).
Does Montana have local income tax?
No. Montana does not allow cities or counties to add a local income tax — the state rate is the only state-level tax on your paycheck. (Compare to states like Ohio or Pennsylvania where local payroll tax adds 1–3% on top.)
How much will I take home on $50,000 in Montana?
About $40,349/year ($1,552 biweekly) for a single filer with no pre-tax deductions. Deductions: federal income tax ~$4,008, Montana state tax ~$1,818 (4.7% on first $21,100 + 5.9% on remainder), Social Security $3,100, Medicare $725. Adding 6% to 401(k) ($3,000) drops MT state tax by about $177 and federal by about $360.
Does the Montana paycheck calculator handle the 0.9% Additional Medicare Tax?
Yes — the Additional Medicare Tax kicks in on wages above $200,000 (single) or $250,000 (MFJ). Employers withhold automatically. If you have multiple jobs each under threshold but combined exceeds, you may owe additional tax at filing. The calculator's base 1.45% covers most workers; high earners should plan for the extra 0.9% on the excess.
Does moving from Montana to Wyoming increase my take-home?
Yes — Wyoming has no state income tax, so a $75,000 single filer keeps about $3,171/year more in Wyoming than in Montana (roughly $61 more per week). The cash gain is bigger the higher the salary: a $150,000 earner keeps roughly $8,300/year more in WY. Montana's advantage is no state sales tax; Wyoming charges 4% state + up to 2% local sales tax, which chips away at the paycheck savings if you spend a large share of your income locally.
How much of a $50,000 salary goes to Montana state tax vs federal?
For a $50,000 single filer, federal income tax after the $15,000 standard deduction is about $4,008 (10.9% effective on gross), Montana state tax is about $1,818 (3.6% effective), FICA is about $3,825. That is a 19.3% total tax bite. Montana state tax alone is under 4% of gross at this income — one of the lower state burdens outside the no-income-tax states.
I'm a Montana resident working remotely for an out-of-state employer — how do I handle the paycheck calculator?
Enter your gross salary as usual. If the out-of-state employer is not registered for Montana withholding (very common for Washington, California, and Texas employers), no Montana tax will appear on your paycheck — the calculator's Montana line shows the tax you'll owe at April filing. Make quarterly estimated payments via Form MT-EST to avoid underpayment penalty (kicks in if the balance due exceeds $500). Full-year Montana residents owe MT tax on worldwide W-2 wages regardless of the employer's state — the residency of the worker, not the employer, drives Montana's claim under Publication 2 (Nonresidents and Part-Year Residents).
If I travel from Montana to work in Washington for a week, do I owe two states?
Potentially yes for that one week, but Montana gives you a credit. Washington itself has no state income tax so no Washington claim exists. But California business trips, Oregon workdays, or Idaho project days can each trigger nonresident withholding by that state on the days you physically worked there. Montana then credits the tax paid to the other state against your Montana liability under MCA § 15-30-2302, preventing double taxation. Track workdays by state on a calendar and keep hotel/rental-car receipts as physical-presence evidence — the audit trail matters if the other state disputes your day count.
How do I calculate Montana state income tax exactly?
Take your Montana taxable income (gross pay minus your federal standard or itemised deduction and any pre-tax 401(k), HSA or health premiums), then apply 4.7% to the first $21,100 for a single filer or $42,200 for married filing jointly, and 5.9% to everything above. On $50,000 of taxable income a single filer owes $2,697 and a joint filer owes $2,444. The effective rate never quite reaches 5.9% because the first bracket is always taxed at 4.7%.
Why is the Montana tax in this calculator different from my payslip?
The calculator's Montana line is an effective-rate estimate rather than a bracket-by-bracket computation, so it lands slightly above the exact figure and will not match a payslip to the cent. It also cannot see your W-4 elections, additional voluntary withholding, or mid-year pay changes. Use the exact two-bracket table on this page — 4.7% to $21,100 then 5.9% — when you need the precise Montana liability for a return or an estimated payment.
