Frequently asked questions

How are bonuses taxed?
A bonus is ordinary income, but it's usually withheld using the IRS flat 22% supplemental rate (38% over $1M), plus Social Security and Medicare. That's withholding — your final tax is settled when you file.
Why is so much taken from my bonus?
The flat 22% federal withholding plus 7.65% FICA means roughly 30% comes off before state tax. If your real marginal rate is lower, you get the difference back at tax time.
Does this include state tax?
No — federal supplemental withholding and FICA only. State bonus withholding varies; add your state on the paycheck calculator for a fuller picture.
