The $16,100 standard deduction leaves $68,900 of taxable income, which puts the last dollar in the 22% federal bracket. Only $18,500 of it is actually taxed at 22% — the income below $50,400 is taxed at the lower rates first, which is why the effective rate lands well under the bracket number. The 22% band runs to $105,700, so a raise of about $36,800 would be needed before any dollar is taxed at 24%.
Montana runs a graduated schedule of 2 bands. After $16,100 of state deductions it taxes $68,900, putting the top dollar in the 5.65% band and producing $3,442 of state tax — 4.05% of gross pay. That is the top band of the state schedule.
Federal income tax of $9,870 on $85,000 of gross pay is 11.61% of the salary, against a 22% marginal bracket — a gap of about 10.4 points. The bracket describes the next dollar earned, not the pay already earned, and quoting the bracket as the tax rate overstates the bill by $8,830 at this salary.
Stacking the 22% federal band, Montana's 5.65%, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 35.3%. A $5,000 raise on top of this salary would therefore add roughly $3,235 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.
