A bonus tax calculator answers the question every employee asks: how much of this bonus will I actually keep? The IRS treats bonuses as supplemental wages, so employers must withhold a flat 22% federal tax on bonuses up to $1 million, plus 7.65% FICA and your state’s income tax. That can take more than a third of the check. Enter your bonus and state rate above for your numbers, or use our take-home pay calculator to estimate regular net pay.
Direct answer: A bonus tax calculator shows how much of your bonus actually lands in your pocket. The IRS requires employers to withhold a flat 22% federal tax on bonuses up to $1 million (37% above that), plus 7.65% FICA and any state tax. On a $10,000 bonus in a 5% state, withholding totals $3,465, leaving a net bonus of $6,535.

Why a Bonus Tax Calculator Uses the 22% Flat Withholding Rate
The IRS classifies bonuses as supplemental wages, which follow different withholding rules than your regular paycheck. Employers can either aggregate the bonus with your wages or use the flat-rate method, and almost all choose the flat rate. Under that method, the IRS requires 22% federal withholding on bonuses up to $1 million, and 37% on amounts above that. The rate applies no matter which tax bracket you are in, which is why a bonus can look over-taxed next to a normal paycheck.
FICA applies to bonuses at the same 7.65% rate as regular wages: 6.2% for Social Security and 1.45% for Medicare. Unlike income tax, FICA is never reconciled at filing, so this portion of the withholding is final. Your state may also withhold on bonuses. Some states use a flat supplemental rate, others apply your regular rate, and several have no income tax at all. Enter your real state rate above for the best estimate.
Clear up the biggest myth about bonuses: they are not taxed at a higher rate than your salary. Your bonus joins your total yearly income and is taxed at your normal marginal rates. The 22% figure only describes what your employer withholds upfront. To see the full picture across salary and extras, compare this result with a paycheck calculator that breaks down a complete paycheck, or use a reverse tax calculator to work backward from a net amount you are aiming to receive.
Bonus Tax Examples: $5,000 to $50,000
The table uses standard withholding: 22% federal, 7.65% FICA, and a 5% state rate. Your numbers shift with your state rate, but the pattern is the same at every bonus size.
| Bonus | Federal (22%) | FICA (7.65%) | State (5%) | Net bonus |
|---|---|---|---|---|
| $5,000 | $1,100.00 | $382.50 | $250.00 | $3,267.50 |
| $10,000 | $2,200.00 | $765.00 | $500.00 | $6,535.00 |
| $25,000 | $5,500.00 | $1,912.50 | $1,250.00 | $16,337.50 |
| $50,000 | $11,000.00 | $3,825.00 | $2,500.00 | $32,675.00 |
Every row shows the same 34.65% effective rate, because each layer is a fixed percentage of the bonus. With no state income tax, the rate drops to 29.65% and a $10,000 bonus nets $7,035.
Key Things to Remember About Bonus Withholding
- Withholding is not your tax bill. The 22% is a deposit toward the tax you owe on your total yearly income. Your final bonus tax is set by your marginal bracket when you file.
- You may get some back. If your actual tax rate is below the 22% withheld, the excess comes back as part of your tax refund.
- You can adjust withholding. A new Form W-4 changes how much is withheld from future paychecks, which can offset an over-withheld bonus.
- State rules differ. Some states use a flat supplemental rate, others your regular rate, and several tax no income at all. Always enter your own state rate.
Bonus Tax Calculator FAQs
Why is my bonus taxed so much?
It is not taxed more heavily, it only looks that way. Employers must withhold a flat 22% federal tax on bonuses, while regular paychecks use graduated W-4 withholding. Add 7.65% FICA and state tax, and more than a third can disappear. The actual tax depends on your total yearly income, not the withholding rate.
Is the 22% bonus tax rate final or just withholding?
Just withholding. The 22% is what your employer must hold back and send to the IRS, not your final rate. At filing time, the bonus is added to your total income and taxed at your marginal rate. If too much was withheld, you get the difference back.
Will I get some of the bonus tax back?
Often, yes. If you are in a bracket below 22%, more was withheld than your actual tax on the bonus, and the surplus returns as part of your refund. Earners in brackets above 22% may owe a little more at filing.
Do bonuses get taxed at a higher rate than regular pay?
No. Bonus income is taxed at the same federal rates as your salary. The confusion comes from the method: regular wages use graduated W-4 withholding, while bonuses use the flat 22% supplemental rate. Your tax return treats both kinds of income identically.
How much is a $10,000 bonus after taxes?
With standard withholding of 22% federal, 7.65% FICA, and 5% state, a $10,000 bonus nets $6,535: $2,200 federal, $765 FICA, and $500 state, for $3,465 total withheld. In a state with no income tax, the same bonus nets $7,035.
Does my state tax my bonus?
In most states, yes. Rules vary: some states apply a flat supplemental rate, others withhold at your regular rate, and a few have no income tax at all. Enter your own state rate in the calculator above for an accurate estimate.
