The $16,100 standard deduction leaves $83,900 of taxable income, which puts the last dollar in the 22% federal bracket. Only $33,500 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 $21,800 would be needed before any dollar is taxed at 24%.
Massachusetts runs a graduated schedule of 2 bands. After $4,400 of state deductions it taxes $95,600, putting the top dollar in the 5% band and producing $4,780 of state tax — 4.78% of gross pay. Its 5% band ends at $1,107,750 of state taxable income, $1,012,150 above where this salary lands.
Federal income tax of $13,170 on $100,000 of gross pay is 13.17% of the salary, against a 22% marginal bracket — a gap of about 8.8 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 $8,830 at this salary.
Stacking the 22% federal band, Massachusetts's 5%, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 34.65%. A $5,000 raise on top of this salary would therefore add roughly $3,268 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.
