Bonus Tax Calculator
See how much of a bonus you'll take home after the 22% federal supplemental withholding and FICA.
About the Bonus Tax Calculator
Employers usually withhold federal tax on bonuses at a flat 22% (37% on supplemental wages over $1 million in a year). This is withholding, not your final tax: when you file, the bonus is taxed with your other income, so you may get some back or owe more.
The formula
Withholding = 22% × bonus (37% above $1M) + 7.65% FICA
Worked example
Example: Take-home before state tax = $7,739
- Inputs: Bonus amount: $11,000; Supplemental wages already paid this year: $0; Filing status: Single.
- Formula: Withholding = 22% × bonus (37% above $1M) + 7.65% FICA
- Result: Take-home before state tax = $7,739
Questions people ask
Why was so much taken out?
Some employers use the aggregate method, adding the bonus to a regular paycheck, which can withhold more.
Can I put my bonus in my 401(k)?
Often yes, if your plan allows; that avoids income tax withholding on that part.
