The $16,100 standard deduction leaves $13,900 of taxable income, which puts the last dollar in the 12% federal bracket. Only $1,500 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 $36,500 would be needed before any dollar is taxed at 22%.
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 $13,900, producing $488 — 1.63% of gross pay.
Federal income tax of $1,420 on $30,000 of gross pay is 4.73% of the salary, against a 12% marginal bracket — a gap of about 7.3 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, Iowa's 3.8%, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 23.45%. A $5,000 raise on top of this salary would therefore add roughly $3,828 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.
