What this income means in Montana
Below $50,000 a single Montana filer stays almost entirely in the 4.7% bracket. At $30,000 the state bill is $653, a 2.18% effective rate, and take-home is $25,632. At $50,000 Montana takes $1,593 and you keep $40,762, about $1,568 every two weeks. Because Montana uses federal taxable income, anything that lowers your federal taxable income, from 401(k) deferrals to HSA contributions, lowers Montana tax too. Check the Montana earned income tax credit if you qualify for the federal one.
