The $16,100 standard deduction leaves $27,580 of taxable income, which puts the last dollar in the 12% federal bracket. Only $15,180 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 $22,820 would be needed before any dollar is taxed at 22%.
New Jersey runs a graduated schedule of 7 bands. After $1,000 of state deductions it taxes $42,680, putting the top dollar in the 5.53% band and producing $866 of state tax — 1.98% of gross pay. Its 5.53% band ends at $75,000 of state taxable income, $32,320 above where this salary lands.
Federal income tax of $3,062 on $43,680 of gross pay is 7.01% of the salary, against a 12% marginal bracket — a gap of about 5.0 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.
A dollar more an hour is $2,080 more a year at 2,080 paid hours. Against a combined marginal rate of about 25.18% -- the 12% federal band, New Jersey's 5.53%, 1.45% Medicare and 6.2% Social Security -- roughly $1,556 of that reaches the bank, or about $0.75 of the extra dollar.
