A Bonus Tax Calculator is an online tool designed to calculate how much tax will be withheld from your bonus payment. Because bonuses are considered supplemental income, they may be taxed differently from your regular salary. This calculator helps you determine your bonus take-home pay by factoring in:
Federal income tax
State income tax (if applicable)
Social Security & Medicare (FICA)
Additional withholding rates
A bonus tax calculator estimates withholdings by inputting your gross bonus, filing status, location, and pay frequency. It factors in federal supplemental rates, FICA (Social Security + Medicare), and state taxes. Tools apply either the percentage method (flat 22% federal) or the aggregate method (bonus + regular pay taxed together).
Start with: Gross Bonus × (Federal Rate + FICA + State Rate). For accuracy, use online calculators and consult your W-4.
Pro tip: Bonuses over $1 million trigger 37% federal withholding—rare for most, but plan.
Federal rules dominate, but states vary. Expect 25-40% total withholding—higher in states like California, lower in Florida (no state tax).
| Tax Type | Rate | Applies To |
|---|---|---|
| Federal Income (Supplemental) | 22% (37% over $1M) | Bonuses under $1M |
| Social Security | 6.2% (up to $176,100 total wages) | All wages |
| Medicare | 1.45% (+0.9% over $200K single) | All wages |
| State (Varies) | 0-13.3% | Location-specific |
FICA totals 7.65%; add state for the full picture. Actual tax liability matches your bracket when filing—over-withholding means a refund.
