How Mississippi bonus withholding works

Short answer: your employer withholds a flat 22% for federal income tax (the supplemental rate), plus 7.65% for Social Security and Medicare, plus Mississippi's flat 4% income tax: about 33.7% of a Mississippi bonus withheld up front. Bonuses aren't actually taxed at a higher rate, though: at tax time they're ordinary income, and any over-withholding comes back in your refund. Here's how each piece works.

  • Federal supplemental rate: Most employers withhold federal income tax from bonuses at a flat 22%, $2,200 on a $10,000 bonus, or 37% above $1 million a year, regardless of your regular bracket.
  • Mississippi flat tax: Mississippi taxes bonuses like all other wages at its flat 4% rate: there's no separate state bonus rate.
  • FICA taxes still apply: Social Security (6.2% up to the annual wage base) and Medicare (1.45%, plus 0.9% for high earners) come out of a bonus like any wage: $765 on $10,000.
  • Over-withholding is common: The flat 22% federal rate is often higher than your actual effective rate, and the difference comes back as a refund. In Mississippi the whole $10,000 nets $6,635 once state tax and FICA are in.

Your actual bonus tax depends on your total annual income, not the bonus alone: these figures assume a $75,000 Mississippi salary. Enter your own numbers above for an estimate that fits your situation.
