Signing Bonus After-Tax Calculator
Calculate your net signing bonus after IRS supplemental withholding and state taxes.
About This Calculator
Signing bonuses are taxed as ordinary income with federal withholding at the 22% supplemental rate. Be aware of clawback provisions — many employers require full repayment if you leave within 1–2 years. When negotiating, gross up the signing bonus by your effective tax rate to understand what you actually need.
