Montana Paycheck Calculator
This 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 2025 Internal Revenue Service annualised percentage method; Social Security at 6.2% up to the 2025 wage base of $176,100.00; 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 2025. 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 $3,596.63 take-home, after federal income tax $786.42, Social Security $310.00, Medicare $72.50 and Montana income tax $234.45.
How the Montana paycheck calculation works
annual gross = gross per period x pay periods per year
federal withholding = IRS percentage method on (annual gross - standard deduction), de-annualised
Social Security = min(annual gross, $176,100.00) 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 2025:
- Annual gross = $5,000.00 x 26 = $130,000.00
- Federal income tax withheld this period = $786.42
- Social Security = $310.00; Medicare = $72.50
- Montana income tax withheld = $234.45
- Take-home = $5,000.00 - $786.42 - $310.00 - $72.50 - $234.45 = $3,596.63
