Income tax in Montana
Montana taxes wage income on a progressive schedule — 2 brackets running from 4.7% to 5.65% for single filers. This calculator applies Montana's real 2026 brackets, its standard deduction ($16,100 single / $32,200 married) and its personal exemption, so the state-tax line follows the actual schedule rather than a flat-rate guess.
Montana income tax brackets for 2026
Single filers. Each rate applies only to the income falling inside that band — these are marginal rates, not a flat rate on the whole salary.
| Taxable income over | Rate |
|---|---|
| $0 | 4.7% |
| $47,500 | 5.65% |
State taxable income is your pay after Montana's standard deduction and personal exemption of $16,100 for a single filer ($32,200 married filing jointly).
How Montana compares
A single filer earning $100,000 pays $4,289 in Montana state income tax — 18th of 51, in the upper-middle of the pack. Maryland ($4,386), Idaho ($4,192) and New Jersey ($4,180) land within a few hundred dollars either way. The headline 5.65% rate is a marginal rate, so it applies to your last dollar, not your whole salary.
Worked example: $100,000 in Montana
Take a single filer on $100,000 in Montana. After the $16,100 standard deduction and personal exemption, state taxable income is $83,900:
| Income band | Rate | Tax |
|---|---|---|
| $0 – $47,500 | 4.7% | $2,232 |
| $47,500 – $83,900 | 5.65% | $2,057 |
| Total state tax | — | $4,289 |
The effective rate works out to 4.3% of gross salary — far below the 5.65% top marginal rate, because only the last slice of income is taxed at that rate.
