Montana Paycheck Calculator 2026 — 4.7%–5.65% Brackets & Take-Home Pay

Estimate Montana take-home pay for 2026 with 4.7% and 5.65% brackets, federal taxable income, FICA and federal withholding — free and instant.

How Montana Paychecks Work

1. Federal tax: progressive brackets 10%–37% minus the $16,100 standard deduction (single, 2026) — same as everywhere.
2. FICA: 6.2% Social Security (up to the $184,500 wage base) + 1.45% Medicare — same as everywhere.
3. State tax: 4.7% to $47,500, 5.65% above. Two brackets for single filers (joint $95,000 at 4.7%), set by House Bill 337, which cut the top rate from 5.9% for 2026. Montana starts from federal taxable income, so the federal $16,100 standard deduction flows straight through.

Worked Example: $85,000 Single Filer

Montana vs Texas vs California on $85,000

The same single filer keeps $65,185.90 in Montana against $68,627 in Texas and $64,007 in California. Montana's two brackets cost $132 a paycheck versus the no-tax states — and beat California by $1,178.90 a year on this salary. Model any state in the calculator.

Federal Withholding on a Montana Paycheck

Only one income tax touches a Montana paycheck: the federal one. Withholding follows the IRS percentage method in Publication 15-T, and three inputs drive it: your filing status, the dependents and credits you claim on Form W-4, and any extra withholding you request. Change any of the three and the same salary produces a different stub, which is why two Montana workers earning $85,000 can take home different amounts.

Federal tax is progressive, which means it applies in slices, not to the whole salary at once. Only the dollars inside each bracket are taxed at that bracket's rate, so a single filer's effective rate is always lower than their top marginal rate. The standard deduction then removes a further slice of income from tax entirely before the brackets even start. Pre-tax items shrink the taxable wage base further: 401(k) contributions and health premiums taken pre-tax reduce the wages the percentages apply to, though the exact treatment differs by deduction type, so read your stub labels rather than assuming.

Our US paycheck calculator models this with an editable withholding percentage instead of hard-coding tables that Congress and inflation adjust every year. If you want the precise official arithmetic for the current year, Publication 15-T is the source the payroll industry itself uses.

FICA: the Two Lines That Always Appear

Below the federal line sit two flat deductions that behave nothing like income tax. Social Security takes 6.2% of wages up to the Social Security Administration's annual wage base, a cap it resets every year. Medicare takes 1.45% of all wages with no cap, plus an additional 0.9% on earnings above $200,000 for single filers ($250,000 joint) — those thresholds are set in statute, not adjusted annually. Your employer matches the 6.2% and the 1.45% dollar for dollar; the additional 0.9% is employee-only.

On the $85,000 example: Social Security is $85,000 x 0.062 = $5,270, comfortably below any recent wage-base cap, and Medicare is $85,000 x 0.0145 = $1,232.50. Together with federal withholding that is the entire deduction stack on a Montana stub. There is no third line, which is exactly the point of the next section.

What Montana Does Differently

Montana's tax is two brackets — 4.7% to $47,500, then 5.65% — and 2026 is the year the top rate fell from 5.9% while the lower bracket widened. Montana has no standard deduction of its own: the return starts from federal taxable income, so the federal $16,100 standard deduction flows straight through. And Montana has no general sales tax at all, so the paycheck stretches further at the till than in almost any other state with an income tax.

Overtime and Pay-Frequency Math

Montana follows the federal Fair Labor Standards Act: non-exempt employees earn 1.5x their regular rate for hours over 40 in a week, with no stricter state daily-overtime rule on top. At $30/hour and a 45-hour week: 40 x $30 = $1,200 straight time, 5 x $45 = $225 overtime, $1,425 gross for the week. Salaried exempt employees are outside this rule under the duties-and-salary-basis test, so a $85,000 salary means $85,000 of gross regardless of hours.

Pay frequency then decides the per-check number without changing the annual total. On $85,000: weekly (52) = $1,634.62; biweekly (26) = $3,269.23; semi-monthly (24) = $3,541.67; monthly (12) = $7,083.33. The existing $85,000 example uses biweekly, the most common Montana schedule. Note that overtime and bonuses can push individual checks into higher withholding on that check alone; withholding per check annualizes the amount, so a spike check withholds as though you earned at that pace all year, with the balance settling at filing time.

New to Montana Paychecks: Reading Your First Stub

A first Montana pay stub surprises newcomers in two ways: there is no state line at all, and the federal and FICA lines look larger than expected because nothing else shares the load. Read it top to bottom. Gross is what you earned. Pre-tax items come off next. FITW (federal income tax withheld) follows your W-4. Then the two FICA lines. The remainder is net. The year-to-date column repeats the same stack cumulatively, which is how you spot a drift early — if YTD federal withholding looks high relative to gross in March, file a new W-4 rather than waiting until filing season. Anyone arriving mid-year should set the W-4 for the new situation on day one: settings calibrated to a previous state system will systematically over- or under-withhold here. Our US paycheck calculator lets you model the stub before the first one prints.

Tipped, Hourly, and Third-Paycheck Months

Montana hospitality runs on tipped wages, and the federal rules are specific. Employers may pay a cash wage as low as $2.13 per hour provided tips bring total hourly earnings to at least the $7.25 federal minimum; if they do not, the employer makes up the difference. Overtime for tipped and hourly staff alike is 1.5 times the regular rate past 40 hours a week. Separately, biweekly earners get two third-paycheck months every year: 26 paychecks cannot divide evenly into 12 months, so two months contain three paydays. The annual total is unchanged, but budgeting monthly on two checks and treating the third as surplus is the standard move. Monthly billers should note the mirror image: semi-monthly schedules never produce a third check, so compare offers on annual gross, not per-check size.

Self-Employed in Montana: What Changes

Without an employer there is no withholding at all, so the full stack lands on you four times a year. Self-employment tax replaces both halves of FICA: 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare, with the additional 0.9% over the statutory thresholds exactly as for employees — 15.3% combined before income tax. Half of that combined amount is deductible when computing income tax, which softens it but does not remove it. Federal estimated payments fall on the fixed calendar: January 15, April 15, June 15 and September 15, shifting to the next business day when the date lands on a weekend. Montana adds nothing on top: no state estimates, no state return, no state-level equivalent to argue about. Miss a federal quarter and interest accrues from the due date, so new freelancers should set calendar reminders before the first April deadline surprises them. Keep 25 to 30 percent of each client payment in a separate account and the quarters stop hurting.

Bonuses, Commissions, and Supplemental Pay

Not everything on a Montana stub follows the salary rules. Bonuses, commissions, severance, and back pay are supplemental wages, and employers may withhold federal tax on them at a flat 22% up to $1 million in a year (37% above that), instead of running them through the W-4 percentage method. That is why a $5,000 bonus can arrive as $3,900 before FICA even though your salary withholding implies a lower rate: $5,000 x 0.22 = $1,100 held back, plus 6.2% Social Security and 1.45% Medicare on top. Montana adds nothing either way, so a Montana bonus beats the same bonus in California by the state slice alone. The flat rate is only withholding, not the final tax — the actual liability settles at filing time against your real marginal rate, which is why bonus-heavy earners in Montana often see meaningful refunds. Overtime already covered above counts as regular wages, not supplemental pay, so the two rules never stack on the same dollar.

The Honest Footnote: Total Burden Matters

Montana's state income tax is moderate at $85,000, but total burden is more than the state tax line. Montana has no general sales tax — one of only five states — so the everyday cost of living is lower at the till, while property tax is set locally and varies by county. There is no local income tax, no state disability or paid-leave deduction, and Social Security is taxed to the extent it is included in federal income. Federal tax, Social Security and Medicare are the same everywhere; it is the state slice that varies.

Living on a Montana Paycheck: What Makes Montana Different

Montana rewrote its income tax for 2026 under House Bill 337: the top rate fell from 5.9% to 5.65%, and the lower 4.7% bracket widened to $47,500 for single filers ($95,000 joint, $71,250 head of household) — the widest the lower bracket has ever been. The two-bracket schedule is only the second year of the simplified system that replaced a seven-bracket ladder in 2024, and the top rate falls again to 5.4% in 2027.

The two-bracket system is young: until 2024 Montana taxed income across seven brackets topping out at 6.75%. Senate Bill 399 collapsed them to 4.7% and 5.9% for 2024, and House Bill 337 — signed in the 2025 session — widened the lower bracket to $47,500 and cut the top rate to 5.65% for 2026, with another cut to 5.4% scheduled for 2027. Long-term capital gains, which used to get a 2% credit against the top rate, now face a flat 3.0% rate under HB 337.

Montana has no standard deduction of its own: the return starts from federal taxable income, so the federal $16,100 standard deduction for single filers in 2026 flows straight into the Montana return, and pre-tax 401(k) and HSA contributions that shrink federal taxable income shrink Montana taxable income by the same dollars. Long-term capital gains get a lower rate — 3.0% for 2026 under HB 337 — while ordinary wages face the two brackets.

On an $85,000 salary, Montana taxable income is $68,900: 4.7% on the first $47,500 is $2,232.50, plus 5.65% on the remaining $21,400 is $1,209.10, for $3,441.60 in Montana tax. There is no city or county income tax in Montana, and no employee-paid state disability or paid-leave program, so beyond federal tax and FICA the only Montana line on a typical stub is that $3,441.60.

Montana also has no general sales tax — one of only five states — so the paycheck stretches further at the till than in almost any other state with an income tax, though property tax is set locally and varies by county. The 2026 minimum wage is $10.85 an hour, up from $10.55 in 2025 and indexed to inflation, with no tip credit: tipped workers get the full $10.85 before tips. For overtime, Montana leans on the federal Fair Labor Standards Act as well — 1.5 times the regular rate once the week passes 40 hours.

One thing Montana does not exempt: Social Security benefits are taxable to the extent they are included in federal taxable income, with no separate Montana subtraction — the figure from line 6b of the federal Form 1040 flows straight onto Form 2. That makes Montana less friendly to retirees than Mississippi, which exempts Social Security entirely, even though Montana's brackets are lower than Maine's at this salary.

Withholding runs through Form MW-4, which employees file with their employer — Montana's version of the federal W-4 — and the return itself is Form 2, due April 15 with an automatic six-month extension to October 15. Estimated payments kick in when the combined liability after withholding and credits will be $500 or more, due April 15, June 15, September 15 and January 15. Pre-tax 401(k) and HSA contributions shrink the Montana bill directly, because the return starts from federal taxable income.

Filing uses Form 2, the Montana Individual Income Tax Return, due April 15, with an automatic six-month extension to October 15 — though any tax owed is still due April 15. Estimated payments are required if your combined liability after withholding and credits will be $500 or more, due quarterly on April 15, June 15, September 15 and January 15. On the $85,000 example the Montana slice is $3,441.60, leaving $65,185.90 a year — about $2,507 every two weeks.
