The rates, what they come to at six salaries, and how Montana compares with every other state, from the same tables as the site's paycheck calculator.
Montana taxes wages in 2 brackets, from 4.7% to 5.65%. On a $75,000 salary that comes to about $3,786 a year, 5.0% of pay, before any state deductions or credits. That is the 11th highest of 51 on that salary, counting DC.
Each rate applies only to the slice of income inside its band, so moving into a higher bracket never raises the tax on the income below it. How brackets work.

The state tax applies Montana's rates to wages before any state standard deduction, exemption or credit, and leaves out local income taxes, so where those exist the real bill is somewhat lower, or higher with a local tax. Take-home also takes off 2026 federal income tax at the standard deduction, Social Security and Medicare. Work out your own paycheck in Montana.
