Bonuses are taxed at the same rate as your regular income, but your employer may withhold more money upfront
Your bonus is subject to federal income tax, Social Security tax, and Medicare tax just like your regular salary. The tax rate itself does not change — a bonus is ordinary income. However, your employer has two legal methods for calculating how much to withhold, and one of them almost always results in a larger withholding amount taken from your bonus check.
The difference is not that bonuses are taxed "more" in the legal sense. It is that your employer withholds more money upfront, which can make your bonus feel smaller than expected. Understanding which withholding method your employer uses helps you see whether you will owe money at tax time or receive a refund.
Key Takeaways
- Bonuses are taxed at your ordinary income tax rate, not a special higher rate, but employers often withhold more money from bonuses than from regular paychecks.
- The IRS allows employers to use either the "aggregate method" (which usually results in higher withholding) or the "percentage method" (which withholds a flat 22 percent or 37 percent depending on bonus size).
- Higher withholding from your bonus does not mean you owe more tax overall — it may just mean you paid more of your annual tax bill upfront.
- You can adjust your W-4 form if you expect a large refund because of bonus withholding, or wait to see your actual tax bill when you file.
The aggregate method: why your bonus withholding feels high
Most employers use the aggregate method when they process a bonus. This method combines your bonus with your regular paycheck for that pay period, calculates the total tax owed on the combined amount, subtracts the tax already withheld from your regular pay, and takes the remainder from your bonus.
Here is a concrete example. Suppose you earn $2,000 every two weeks and your employer withholds $300 per paycheck. You receive a $5,000 bonus in the same pay period. Your employer adds the $5,000 to your $2,000 regular pay, calculates tax on $7,000 total, and withholds enough to cover the full tax bill. Since your regular $300 withholding only covers part of the tax on $7,000, the remaining withholding comes out of your bonus. You might see $2,000 or more withheld from that $5,000 bonus.
The aggregate method can push you into a higher tax bracket temporarily for that single pay period, even though your annual income has not changed. That temporary bracket bump is why the withholding looks so steep.
The percentage method: a flat withholding rate
Some employers use the percentage method instead. Under this method, your employer withholds a flat percentage from your bonus without combining it with your regular paycheck. The IRS sets these rates: 22 percent for most bonuses, or 37 percent if your bonus is over $1 million in a single year.
The percentage method usually results in lower withholding than the aggregate method, but it is less common. Your employer chooses which method to use, and you can ask your payroll department which one they explore. The choice is up to them, not you.
Even under the percentage method, the amount withheld is still just a withholding — it is not the final tax you owe. Your actual tax liability is determined when you file your tax return.
Why withholding is not the same as your actual tax bill
Withholding is money your employer sends to the IRS on your behalf throughout the year. It is an estimate based on the W-4 form you filled out. Your actual tax bill depends on your total income for the entire year, your filing status, your deductions, and any tax credits you claim.
If your employer withholds $2,000 from a $5,000 bonus using the aggregate method, that does not mean you owe $2,000 in tax on that bonus. It means $2,000 was sent to the IRS as a prepayment. When you file your tax return in April, you will see whether that withholding was too much (you get a refund) or too little (you owe more).
Many people receive a refund after getting a large bonus, because the aggregate method withholds conservatively. That refund is your own money that was withheld too early — it is not a tax break.
How to estimate your actual tax on a bonus
To find out what you will actually owe on a bonus, you need to know your marginal tax bracket for the year. Your marginal bracket is the tax rate that applies to your last dollar of income.
For 2024, the federal income tax brackets for single filers range from 10 percent to 37 percent depending on total income. If you earn $50,000 and receive a $10,000 bonus, your bonus is taxed at your marginal rate, not at a special bonus rate. You also owe 6.2 percent Social Security tax and 1.45 percent Medicare tax on the bonus (unless you have already hit the Social Security wage cap for the year).
Add those percentages together to estimate your true tax rate on the bonus. If your marginal bracket is 22 percent, plus 6.2 percent Social Security, plus 1.45 percent Medicare, your actual tax is roughly 29.65 percent. If your employer withheld 40 percent using the aggregate method, you will likely receive a refund of the difference.
Adjusting your W-4 if you expect a large refund
If you know you will receive a large bonus and you want to reduce the withholding, you can adjust your W-4 form before the bonus is paid. You can claim additional allowances or request a specific dollar amount to be withheld less from each paycheck.
Talk to your payroll department about the timing and size of your bonus. They can tell you which pay period it will be in and which withholding method they use. With that information, you can estimate the withholding and adjust your W-4 accordingly.
Keep in mind that adjusting your W-4 changes your withholding for all paychecks going forward, not just the bonus. If you only want to adjust for the bonus, you might instead choose to wait and claim the refund when you file your tax return — that way your regular paycheck withholding stays the same.
State and local taxes on bonuses
Your bonus is also subject to state income tax (in states that have it) and sometimes local income tax. The withholding rules vary by state. Some states use a method similar to the federal aggregate method, while others use a flat percentage.
Your pay stub will show state and local withholding separately from federal withholding. If you live in a state with no income tax, you will not see state withholding on your bonus. If you live in a state with income tax, the state withholding may add another 3 to 10 percent or more to the total amount withheld, depending on your state and income level.
Frequently Asked Questions
Is there a special tax rate for bonuses?
No. Bonuses are taxed at your ordinary income tax rate. The difference you notice is in withholding — your employer may withhold more money upfront from a bonus than from a regular paycheck, but that does not change the actual tax rate applied to the bonus income.
Can I avoid withholding on my bonus?
No. Your employer is required by law to withhold federal income tax, Social Security tax, and Medicare tax from your bonus. You cannot opt out. However, you can adjust your W-4 to reduce withholding on future paychecks if you expect a large refund.
Will I owe more tax if I get a bonus?
Your bonus increases your total income for the year, so you will owe more tax overall. However, the tax rate on the bonus itself is the same as the rate on your regular income. Whether you owe additional tax at filing time depends on how much was withheld and what your total income and deductions are.
Why did my bonus withholding seem so high?
Your employer likely used the aggregate method, which combines your bonus with your regular paycheck for that pay period and calculates tax on the combined amount. This can temporarily push you into a higher bracket for that one paycheck, resulting in higher withholding than you might expect.
Do I get a refund if too much was withheld from my bonus?
Possibly. If your employer withheld more than your actual tax liability, you will see a refund when you file your tax return. The refund is the difference between what was withheld and what you actually owe.
