About This Calculator
Bonuses are treated as supplemental wages by the IRS, which means they're withheld differently from regular salary. Depending on your employer's payroll method, you might see 22% flat federal withholding or aggregate withholding stacked on top of your regular pay. This calculator shows both scenarios so there are no surprises when that bonus lands.

Frequently Asked Questions
The IRS treats bonuses as supplemental wages. When paid separately from your regular paycheck, the default flat withholding rate is 22% for federal tax. Some states like California add another 10.23%. When combined with your regular paycheck (the aggregate method), withholding is calculated as if the bonus pushed you into a higher bracket—often resulting in more tax held upfront.
