How much will I take home from a $5,000 bonus in Missouri?

On a $5,000 bonus: federal 22% = $1,100; Social Security 6.2% = $310; Medicare 1.45% = $72.50; Missouri 4.7% = $235.00. That leaves about $3282.50 take-home (before 401(k) or benefits). Use the calculator for your own amount.

Why is so much tax taken out of my bonus?

Bonuses use the IRS flat "supplemental wage" withholding rate of 22% rather than your normal paycheck rate, which can look high if your marginal rate is below 22%. It is only withholding — if too much is withheld, you get it back when you file your annual return.
