Estimate for information only. ## Withholding is not the final tax Most employers withhold a flat 22% federal tax from a bonus. Your actual tax on it depends on your bracket, so the 22% can be too much or too little: - **$35,000 salary, $5,000 bonus:** $1,100 withheld, but the bonus adds only $600 of federal tax. About $500 comes back at tax time. - **$80,000 salary, $10,000 bonus:** $2,200 withheld and about $2,200 owed, roughly even. - **$250,000 salary in California, $30,000 bonus:** $6,600 withheld but $9,830 owed, a $3,230 shortfall, plus $3,180 of California tax. ## The two withholding methods **Flat rate:** 22% of the bonus, available when the employer has withheld tax from your regular pay. **Aggregate:** the bonus is added to a regular paycheck and taxed as if that bigger amount were your normal pay, which can withhold more or less than the flat rate. Above $1,000,000 of supplemental wages in a year, 37% is mandatory on the excess. Source: [IRS Publication 15 (2026), Supplemental wages](https://www.irs.gov/publications/p15).

Employers usually withhold a flat 22% federal tax from bonuses, plus 7.65% for Social Security and Medicare and any state tax. That is withholding, not your final tax: if your bracket is below 22%, part of it comes back in your refund. ### What is the federal tax rate on bonuses in 2026? 22% under the flat-rate method, and 37% on supplemental wages above $1,000,000 in the year. Employers can instead use the aggregate method, adding the bonus to a regular paycheck and withholding as if it were normal pay. ### Is a bonus taxed differently from salary? No. At year end a bonus is ordinary income, taxed at the same rates as your salary. Only the withholding method differs. ### Do bonuses count toward Social Security? Yes, up to the $184,500 wage base for 2026, counting your salary first. Medicare applies to all of it. ## Related guides - [Explainer · PaychecksSocial Security tax cap 2026: wage base and maximum taxIn 2026, Social Security tax stops at $184,500 of wages: up to $11,439 for employees and $22,878 if self-employed.
