How Montana taxes your paycheck
Montana uses a graduated income tax with 2 brackets, from 4.7% on the first slice of taxable income to 5.65% on income over $47,500 for single filers. Each rate applies only to the income inside its bracket, so moving into a higher bracket never lowers your take-home pay. Before the rates apply, Montana allows a standard deduction of $16,100 for single filers and $32,200 for married couples filing jointly.
On a $75,000 salary, a single filer owes about $2,877 in Montana income tax for 2026, an effective state rate of 3.84%.
| Rate | Single: taxable income | Married filing jointly: taxable income |
|---|---|---|
| 4.7% | $0 | $0 |
| 5.65% | over $47,500 | over $95,000 |

What this estimate leaves out
State disability insurance and paid family-leave contributions and local income taxes are not included, and the federal figures assume the standard deduction with no credits such as the Child Tax Credit. Head-of-household and married-filing-separately returns use the state's single schedule, which a few states set separately.
