Bonus withholding is tax taken from a bonus paycheck during the year; bonus tax is part of the taxpayer's final income-tax liability after the return applies all income, deductions, credits, and payments. In 2026, a separately identified $1,000 supplemental wage payment may use 22.00% federal withholding, or $220, but $220 is a prepayment rather than a special final bonus tax rate.
What bonus withholding vs bonus tax means
Withholding is money sent toward estimated tax during the year, while tax liability is the final amount determined under the taxpayer's return and applicable rules. Withholding describes a payroll collection method; marginal tax analysis describes how taxable income is taxed when the return is calculated.

Bonus withholding vs. bonus tax: why the paycheck result is not your final tax bill: worked example
An employee receives a separately identified $1,000 bonus. Under the IRS flat-rate method applicable to qualifying supplemental wages, federal income-tax withholding is $220 at 22.00%. The paycheck can also show payroll, state, or other deductions. At filing, the $1,000 is included in taxable income with other wages; the final tax effect depends on the taxpayer's whole return. A $220 withholding can be too high, too low, or equal to final liability.
How to calculate bonus withholding vs bonus tax
Read whether the bonus is separately identified, whether regular wages had federal withholding, and the employer's selected method. Record gross bonus, federal withholding, payroll taxes, state withholding, and net deposit separately. Do not infer year-end liability from a single pay stub.

Common mistakes
Do not say every bonus is taxed at 22.00%, mistake a withholding percentage for a total tax rate, omit Social Security or Medicare treatment from a net-pay check, or use a current-year rule for another tax year.
Where this calculation stops
Supplemental-wage rules can differ when paid with regular wages, when withholding conditions differ, or above the statutory threshold. State and local rules, credits, deductions, and other income are outside this illustration.
