The $16,100 standard deduction leaves $38,900 of taxable income, which puts the last dollar in the 12% federal bracket. Only $26,500 of it is actually taxed at 12% — the income below $12,400 is taxed at the lower rates first, which is why the effective rate lands well under the bracket number. The 12% band runs to $50,400, so a raise of about $11,500 would be needed before any dollar is taxed at 22%.
South Dakota levies no individual income tax on wages, so nothing is withheld for state income tax and the whole $55,000 is reduced by federal income tax and FICA alone. That also means the state share does not change as this salary rises — the only progression left in the figures above is federal.
Federal income tax of $4,420 on $55,000 of gross pay is 8.04% of the salary, against a 12% marginal bracket — a gap of about 4.0 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 $2,180 at this salary.
Stacking the 12% federal band, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 19.65%. A $5,000 raise on top of this salary would therefore add roughly $4,018 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.
