This free Montana paycheck calculator shows your 2026 take-home pay. It covers federal income tax, Montana state tax, Social Security and Medicare. Montana uses two rates. A lower band is taxed at 4.7%, and everything above it at 5.65%. Which rate applies depends on your filing status and your taxable income.
The top rate came down for 2026. HB 337 cut it from 5.9% to 5.65% and widened the lower band. Another cut is already on the books for 2027, down to 5.4%. No Montana city or county charges an income tax. Montana has no general sales tax either.
How Montana taxes your paycheck in 2026
A single filer pays 4.7% on taxable income up to $47,500. Every dollar above $47,500 is taxed at 5.65%. Head of household filers get a wider low band, up to $71,250. Married couples filing jointly pay 4.7% up to $95,000. Only the slice above your line pays the higher rate.
Montana starts from your federal taxable income. So the federal standard deduction is what lowers your Montana tax. Montana writes no deduction of its own and gives no personal exemption. That has been the rule since the 2024 tax year. So your federal choices drive your Montana bill.
SB 399 made that change back in 2021, with a delayed start. It repealed the old Montana standard deduction. It also repealed the old deduction for federal income tax paid. Older guides still mention both, so check the date on anything you read. Use the year on the guide as your first check.
Two rates, and where the line falls
Work an example. A single filer earning $60,000 subtracts the federal standard deduction first. What is left is Montana taxable income. Part of it sits under $47,500 and is taxed at 4.7%. Only the part above that line pays 5.65%. Your Montana tax is the two pieces added together.
The low band is wide, so a large share of income is taxed at 4.7%. Your effective state rate lands below the 5.65% headline. The wider that low band grows, the bigger the gap gets. Watch the rate on a bonus, though, because that top dollar pays 5.65%.
HB 337 widened the low band as well as cutting the top rate. Both changes push in the same direction. Your take-home pay in 2026 is higher than it would have been under the old rules. The scheduled 2027 cut to 5.4% pushes further. Your withholding tables should already reflect the 2026 numbers.
No sales tax, and what this page leaves out
Montana has no general sales tax. That is rare, and it matters here. Income tax carries more of the load than it does in neighboring states. A Montana wage earner pays state tax on payday rather than at the till. Your paycheck feels that difference every two weeks.
No Montana city or county charges an income tax. Billings, Missoula, Great Falls and Bozeman take nothing from your wages. Some resort towns charge a local resort tax. That falls on lodging and retail sales, so it does not touch your paycheck. So your workplace address does not change your Montana withholding.
A traditional 401(k) lowers your federal taxable income, so it lowers your Montana tax as well. It does not lower your Social Security or Medicare wages. Payroll HSA money lowers all three. Credits like the Montana earned income credit arrive at filing time. Use the fields above to add your filing status and your pre-tax savings.
