Montana Paycheck Calculator 2026
This Montana paycheck calculator shows what actually lands in your bank account each pay period in 2026. Enter your gross salary and the tool applies 2026 federal brackets, Social Security and Medicare, and Montana withholding, then splits the result across weekly, biweekly, semi-monthly and monthly pay schedules. Montana uses a progressive income tax with 2 brackets running from 4.70% up to 5.90%, applied after a state standard deduction of $16,100.

How Montana payroll withholding works
Every Montana paycheck is reduced in the same order: pre-tax deductions first (401(k), HSA, employer health premiums), then federal income tax on what remains, then FICA on your full gross, then Montana state withholding.
FICA is fixed nationwide in 2026: 6.2% Social Security on the first $184,500 of wages and 1.45% Medicare on everything, with an extra 0.9% Medicare surtax above $200,000. Only the state layer changes when you move, which is why two workers earning the same salary in Montana and Wyoming see different deposits.
Montana has no state sales tax — one of only five US states without a general sales tax.
Pay frequency in Montana
Most energy employers around Billings run biweekly payroll (26 checks a year), while public-sector and salaried office roles often use semi-monthly (24 checks). Biweekly means two months each year contain three paychecks — a useful budgeting quirk if your rent is around $1,150.
Switching frequency does not change your annual tax; it only changes how withholding is spread. If your employer withholds per-period using annualized tables, a three-paycheck month can look artificially light on tax.
Budgeting a Billings paycheck
Cost of living in Montana sits 2% above the national average (index 102), median household income is $66,800, and a one-bedroom apartment in Billings rents for roughly $1,150 a month.
Montana consolidated its 7-bracket system to just two brackets (4.7% and 5.9%) in 2026 — paired with a federal-conforming standard deduction.
Local and payroll taxes Montana adds on top
Montana adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Montana has no state sales tax — one of only five US states without a general sales tax.
Payroll systems apply these local layers automatically, so check a real Montana pay stub against the estimate above: a missing local tax line is the usual reason a paycheck comes in lower than a state-only calculator suggests.
Working across a state line from Montana
Montana holds income-tax reciprocity agreements with North Dakota. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Billings resident spending part of the year at a client site in Wyoming may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Montana tax bill
Montana charges no general sales tax, homeowners pay an average effective property tax of 0.74% of market value, and the minimum wage in force during 2026 is $10.85 an hour.
No general sales tax; some resort towns levy a local option tax.
Income tax is only one part of a state's take. Montana recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Montana taxes most retirement income, including Social Security above federal thresholds, with a modest subtraction at 65+.
Montana vs Wyoming on the same salary
On a $75,000 salary, a single filer keeps about $58,363 a year in Montana against roughly $61,593 in Wyoming — a difference of $3,229, or $269 a month.
Effective combined rates are 22.2% in Montana and 17.9% in Wyoming. Set that gap against living costs: index 102 here versus 96 there, with property tax at 0.74% and 0.61% respectively.
