In the U.S., bonuses are generally handled as supplemental wages for payroll withholding. That means the paycheck impact can look harsher than your normal salary rate, even though the final tax is reconciled later. The IRS explains the withholding methods in Publication 15 and Publication 15-T.
Payroll withholding is a prepayment, not the final tax bill. The broader IRS overview on tax withholding explains how withholding fits into your yearly return.
Employers may use a flat-rate or aggregate method for supplemental wages. Those method rules are documented in Publication 15 and Publication 15-T.
Retirement contributions, payroll taxes, benefits, or garnishments can materially change take-home pay. Add those fixed amounts in the other deductions field for a closer estimate.
