The $16,100 standard deduction leaves $21,340 of taxable income, which puts the last dollar in the 12% federal bracket. Only $8,940 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 $29,060 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 $36,440, putting the top dollar in the 3.5% band and producing $593 of state tax — 1.58% of gross pay. Its 3.5% band ends at $40,000 of state taxable income, $3,560 above where this salary lands.
Federal income tax of $2,313 on $37,440 of gross pay is 6.18% of the salary, against a 12% marginal bracket — a gap of about 5.8 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 23.15% -- the 12% federal band, New Jersey's 3.5%, 1.45% Medicare and 6.2% Social Security -- roughly $1,598 of that reaches the bank, or about $0.77 of the extra dollar.
