Across 2,080 paid hours a year at 40 hours a week. State income tax only — local and municipal taxes are excluded.
The $16,100 standard deduction leaves $67,100 of taxable income, which puts the last dollar in the 22% federal bracket. Only $16,700 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 $38,600 would be needed before any dollar is taxed at 24%.
Iowa taxes wage income at a single 3.8% rate rather than a graduated schedule, so the state share does not change shape as the salary rises. After $16,100 of deductions the state taxes $67,100, producing $2,510 — 3.02% of gross pay.
Federal income tax of $9,474 on $83,200 of gross pay is 11.39% of the salary, against a 22% marginal bracket — a gap of about 10.6 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.
A dollar more an hour is $2,080 more a year at 2,080 paid hours. Against a combined marginal rate of about 33.45% -- the 22% federal band, Iowa's 3.8%, 1.45% Medicare and 6.2% Social Security -- roughly $1,384 of that reaches the bank, or about $0.67 of the extra dollar.
