How $18 an hour is taxed in Montana
Full time, $18 an hour is $37,440 a year (2,080 hours). Here is how each tax on that income is calculated.
1. Federal income tax: $2,313
Start with $37,440 of wages and subtract the $16,100 standard deduction. That leaves $21,340 of taxable income, taxed in brackets:
| Taxable income band | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 to $12,400 | 10% | $12,400 | $1,240 |
| $12,400 to $50,400 | 12% | $8,940 | $1,073 |
| Federal income tax | $2,313 | ||
2. Montana income tax: $1,003
Montana starts from federal taxable income, $21,340. That leaves $21,340 of Montana taxable income.
| Taxable income band | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 to $47,500 | 4.7% | $21,340 | $1,003 |
| Montana income tax | $1,003 | ||
3. Social Security and Medicare: $2,864
Social Security is 6.2% of wages up to the $184,500 wage base ($2,321), and Medicare is 1.45% of all wages ($543).
Result: $37,440 minus $6,180 in total tax leaves $31,260 a year, an effective tax rate of 16.5%.
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.
