Bonus Tax Calculator

Estimate how much of your bonus you may actually take home after federal withholding, state withholding, and payroll taxes.

This calculator estimates bonus withholding using either the flat supplemental withholding method or an aggregate estimate. It also includes a state estimate and optional Social Security and Medicare withholding. Actual payroll withholding may differ depending on your employer’s payroll system, your Form W-4 settings, pre-tax deductions, local taxes, and state-specific rules.
