How Supplemental Wages & Bonuses Are Taxed
The IRS treats bonuses, commissions, severance, and incentive payouts as supplemental wages. Employers generally withhold federal income tax on bonuses using one of two IRS methods:
- Percentage Method (Flat Rate): If your bonus is under $1 million, the federal government requires a flat 22% withholding rate.
- Aggregate Method: Your bonus is added to your regular paycheck, which can push you into a higher marginal tax bracket for that single period.
