Montana's income tax is graduated: 2 brackets running from 4.7% to 5.9%, the 16th-highest top rate of the 51 jurisdictions. The top rate applies to a single filer's taxable income above $21,100. Because that top bracket starts so low, Montana behaves like a flat 5.9% tax for most full-time earners — the graduated part only shapes the first few thousand dollars. Joint filers get exactly double the bracket widths at every rate, so a married couple pays what two single filers on half the income each would pay. Heads of household get a third schedule of their own, wider than the single one. A single filer subtracts a $15,750 standard deduction before the rates are applied.

Assumptions
- 2026 Publication 15-T percentage-method tables (automated payroll systems) with a 2020-or-later Form W-4 and no Step 4(a)/4(b) entries.
- Social Security at 6.2% up to the 2026 wage base of $184,500 and Medicare at 1.45% plus 0.9% over $200,000 (IRS Topic 560), both averaged evenly across the year.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results — annualized, then divided by your pay periods rather than run through that state's own withholding formula. The source URL, year and per-state simplifications are printed above the results.
- No local or city income taxes, state disability insurance, HSA/FSA deductions or supplemental-wage withholding. A state that isn't listed falls back to the flat rate you enter.

How the neighbours compare
Montana borders 4 other jurisdictions. Moving across a state line is the one way most people can actually change which of these schedules applies to them, so here is the same income run through each of them.
| State | Rate structure | Per paycheck | A year |
|---|---|---|---|
| Montana | 4.7% – 5.9% | $131.52 | $3,420 |
| Idaho | 0% – 5.3% | $117.09 | $3,044 |
| North Dakota | 0% – 2.5% | $9.24 | $240 |
| South Dakota | No income tax | $0.00 | $0 |
| Wyoming | No income tax | $0.00 | $0 |
State income tax on a single filer, after each state’s own deductions. Federal tax is identical wherever you live, so the difference between these rows is the whole difference.
What these Montana figures leave out
Recorded against Montana in the data rather than glossed over, because they change real bills.
- Montana had not published 2026 tables when this was compiled. House Bill 337 cuts the top rate to 5.65% for 2026 and widens the lower bracket substantially, so 2026 tax will be lower than shown here — this state needs review before it is relied on for 2026.
- Montana starts from federal taxable income, so the deduction applied is the federal one. The standard deduction is the federal amount this state adopts: $15,750 single, $31,500 married filing jointly, $23,625 head of household for 2025 (IRS Rev. Proc. 2024-40, as amended by Rev. Proc. 2025-32 §3.01).
- Long-term capital gains are taxed at lower rates (3.0% / 4.1%) than the ordinary rates shown.
Frequently asked questions
▸Does Montana withhold state income tax from your paycheck?
Yes. On a $78,000 salary paid every two weeks, roughly $131.52 a paycheck goes to Montana income tax — about $3,420 over a year — on top of federal withholding and FICA.
▸What is taken out of a paycheck in Montana?
Federal income tax withheld under the IRS Publication 15-T tables, Social Security at 6.2% up to the annual wage base, and Medicare at 1.45%, plus Montana income tax from its 2025 schedule. Pre-tax 401(k) and health premiums come out before the income-tax lines are worked out.
▸How is Montana withholding calculated here?
Your pay is annualised, run through Montana's 2025 schedule — 2 brackets from 4.7% to 5.9% — with its own standard deduction, and the resulting annual liability is spread evenly over your pay periods. That is the annual tax you actually owe; a real Montana withholding table can differ by a few dollars a period and squares up when you file.
▸Are these Montana figures up to date?
They are the tax year 2025 figures, taken from Montana Department of Revenue — 2025 Montana tax tables and deductions and last checked on 2026-09-09. Montana had not published a 2026 schedule when this was compiled, so the 2025 one is shown rather than an estimate.
