Mississippi Bonus Tax Calculator

22% is the flat rate many employers use to withhold federal tax on bonuses (IRS Publication 15), not a special bonus tax rate. On a $75,000 salary, that withholds about $2,200 federal tax on a $10,000 bonus. At filing, the bonus adds about $2,200 in federal tax — almost exactly what the flat 22% method withheld.

No — a bonus is ordinary income taxed at the same federal brackets as your salary when you file. The difference is withholding: employers commonly withhold a flat rate on bonuses instead of the regular payroll tables. Mississippi may withhold bonuses differently too — many states set their own withholding rate for bonuses, which can differ from the state income tax a bonus actually adds.

For a single filer earning $75,000, about $2,200 is withheld for federal tax (flat method), $765 for Social Security and Medicare, and the bonus adds $400 in Mississippi state income tax at filing — about $6,635 kept after federal withholding, FICA, and the state income tax the bonus adds. Many states set their own withholding rate for bonuses, which can differ from the state income tax a bonus actually adds.
