Bonus Calculator

This is the fast version of the bonus tax calculator: one number in, one number out. It applies the same supplemental-wage math — 22% federal, 7.65% FICA, state supplemental rate — without the extras.

Quick answer: Take-home ≈ bonus × (1 − 0.22 − 0.0765 − state rate). A $5,000 bonus nets about $3,520 in a no-tax state and about $3,270 in a 5% state.

Withholding-level estimate. The 22% federal rate is a prepayment, not your final tax — excess withholding is refunded when you file. FICA of 7.65% assumes you are under the Social Security wage base for the year. Not tax advice.
