The $16,100 standard deduction leaves $28,900 of taxable income, which puts the last dollar in the 12% federal bracket. Only $16,500 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 $21,500 would be needed before any dollar is taxed at 22%.
Mississippi runs a graduated schedule of 2 bands. After $8,300 of state deductions it taxes $36,700, putting the top dollar in the 4% band and producing $1,068 of state tax — 2.37% of gross pay. That is the top band of the state schedule.
Federal income tax of $3,220 on $45,000 of gross pay is 7.16% of the salary, against a 12% marginal bracket — a gap of about 4.8 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.
Stacking the 12% federal band, Mississippi's 4%, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 23.65%. A $5,000 raise on top of this salary would therefore add roughly $3,818 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.
