Montana Paycheck Calculator
Figure basis: Official Montana Department of RevenueThis Montana paycheck calculator estimates your take-home pay after the taxes withheld from a typical wage. Enter your gross pay, choose how often you are paid (weekly, every two weeks, twice a month or monthly) and select your filing status to see a full breakdown of every deduction and your net pay. The estimate combines four withholdings: federal income tax, calculated with the 2026 Internal Revenue Service annualised percentage method; Social Security at 6.2% up to the 2026 wage base of $184,500.00; Medicare at 1.45% on all wages; and Montana state income tax withholding, applied with the brackets published by the Montana Department of Revenue for tax year 2026. Results update as you type and the page link captures your inputs so you can save or share a calculation. This estimate covers federal withholding, FICA and state income tax only; State Disability Insurance where a state levies it, and any city or county local income tax, are not included and are noted separately. Use it to check a payslip, compare an offer, or plan a pre-tax contribution.
A $5,000 biweekly paycheck (single filer) in Montana is about $3,585.66 take-home, after federal income tax $766.69, Social Security $310.00, Medicare $72.50 and Montana income tax $265.14.
How the Montana paycheck calculation works
annual gross = gross per period x pay periods per year
federal withholding = IRS Pub 15-T annualised percentage method, de-annualised
Social Security = min(annual gross, $184,500.00) x 6.2% / periods
Medicare = annual gross x 1.45% / periods
state withholding = Montana income tax on annual gross / periods
take-home = gross per period - federal - Social Security - Medicare - state
Worked example
A single filer paid $5,000.00 every two weeks (26 pay periods a year) in Montana, for 2026:
- Annual gross = $5,000.00 x 26 = $130,000.00
- Federal income tax withheld this period = $766.69
- Social Security = $310.00; Medicare = $72.50
- Montana income tax withheld = $265.14
- Take-home = $5,000.00 - $766.69 - $310.00 - $72.50 - $265.14 = $3,585.66
Montana's two rates, and the deduction that left the state form
Montana withholds state income tax at two rates for 2026: 4.7% on the lower band and 5.65% above it, with the break at $47,500 for a single filer, $95,000 for a married couple filing jointly, and $71,250 for a head of household. HB 337 (2025) cut that top rate from 5.9% and widened the lower band, so most wage earners will see a slightly larger take-home paycheck this year than last.
The structural change matters more than the rates. Montana no longer has its own standard deduction or personal exemptions. Its tax now begins from your federal taxable income, so the federal standard deduction you already claimed flows straight through and reduces the Montana base automatically. There is no separate state deduction to add on the paycheck.
Two caveats keep this a wage estimate rather than a full answer. Long-term capital gains are taxed on their own lower schedule of 3.0% and 4.1%, so anyone with significant investment income owes a different effective rate than a salary-only figure suggests. And residents age 65 and over get a separate subtraction from federal taxable income, roughly $5,660 for 2025 and indexed each year, which is not reflected in a standard paycheck. Montana levies no local income tax, so for a straightforward wage the two-rate schedule above is the complete state withholding.
