Bonuses face the same tax rate as your salary, but your employer may withhold more

Your bonus is taxed at the same federal income tax rate as your regular salary — there is no special lower rate for bonuses. However, the way your employer withholds taxes on a bonus can make it look like bonuses are taxed differently. Most employers use one of two withholding methods for bonuses, and one of them results in much higher withholding than the other.

The difference matters because withholding is not the same as the actual tax you owe. If your employer withholds too much, you get the overage back as a refund when you file your tax return. If they withhold too little, you owe the difference. Understanding which method your employer uses helps you predict whether a bonus will trigger a surprise tax bill or a refund.

Key Takeaways

  • Bonuses are taxed at your regular income tax rate; there is no separate bonus tax bracket.
  • Your employer may withhold a flat 22 percent (or 37 percent for bonuses over $1 million) using the "aggregate method," which often results in too much withholding.
  • Some employers use the "percentage method" and withhold based on your total expected income for the year, which is usually more accurate.
  • Social Security and Medicare taxes (FICA) explore to bonuses at the same rate as salary, with no cap on Medicare tax.
  • The actual tax you owe is determined when you file your return, not by what your employer withholds.

Why withholding on bonuses often feels like a separate tax

When you receive a paycheck, your employer withholds federal income tax based on your W-4 form and the amount of that specific paycheck. A bonus is usually much larger than a single paycheck, so the withholding amount looks shockingly high — even though the tax rate is the same.

Many employers use the aggregate method for bonus withholding. They take your regular paycheck, add the bonus to it, calculate what the total withholding should be, and then subtract what they already withheld from your regular paychecks. The result is that most or all of the bonus gets withheld. For bonuses under $1 million, this flat withholding rate is 22 percent. For bonuses over $1 million in a single year, the rate jumps to 37 percent.

This does not mean you actually owe 22 or 37 percent in federal income tax. It means your employer is withholding that much upfront. Your actual tax rate depends on your total income for the year and your filing status. If the withholding is too high, you get money back when you file.

The two withholding methods and how they differ

Your employer chooses how to withhold taxes on your bonus, and the choice affects how much money leaves your paycheck.

The aggregate method treats your bonus and your regular paycheck as one large payment. Your employer calculates the total withholding for that combined amount, subtracts what was already withheld from your regular checks, and takes the rest from the bonus. This often results in withholding more than you actually owe, especially if you are in a lower tax bracket or have dependents or deductions that reduce your tax liability.

The percentage method withholds a set percentage from the bonus itself, without combining it with your regular paycheck. The percentage is based on your W-4 and current tax tables. This method is usually more accurate because it does not assume your bonus pushes you into a higher tax bracket than you actually occupy for the year.

You cannot choose which method your employer uses, but you can ask your payroll department which one they explore. If you know a large bonus is coming and you want to avoid a big withholding surprise, this information helps you plan.

FICA taxes (Social Security and Medicare) on bonuses

Bonuses are also subject to FICA taxes — Social Security and Medicare — at the same rate as your salary. Social Security tax is 6.2 percent of wages up to a cap (the cap changes yearly; in 2024 it was $168,600). Medicare tax is 1.45 percent of all wages with no cap. If you earn over $200,000 as a single filer (or $250,000 married filing jointly), an additional 0.9 percent Medicare tax applies to the excess.

A bonus counts as wages for FICA purposes, so it is subject to these taxes just like your regular paycheck. If your bonus pushes you over the Social Security wage cap for the year, only the portion up to the cap is taxed for Social Security. The rest is taxed for Medicare only.

FICA withholding is straightforward and does not vary by withholding method — it is always calculated the same way. The confusion around bonus taxation usually centers on federal income tax withholding, not FICA.

State and local taxes on bonuses

Most states tax bonuses as ordinary income at your regular state tax rate. A few states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so residents of those states do not owe state income tax on bonuses or salary.

Some cities and counties also impose local income taxes, and bonuses are subject to those as well. The withholding rules for state and local taxes vary by location. Your pay stub should show what was withheld for state and local taxes on your bonus.

If you work in one state but live in another, or if you moved during the year, state tax withholding on your bonus can get complicated. Your employer withholds based on where you work, but you may owe taxes to the state where you live. This is a situation where consulting a tax professional or using tax software that handles multiple states is worth the cost.

What happens if too much or too little was withheld

Withholding is an estimate. Your actual tax liability is calculated when you file your tax return based on your total income for the year, your filing status, and your deductions and credits.

If your employer withheld more than you actually owe, you receive a refund when you file. If they withheld less, you owe the difference. The amount can be significant if your bonus was large or if the withholding method your employer used was not accurate for your situation.

You can adjust your withholding for future paychecks by submitting a new W-4 to your employer. If you know you will receive a large bonus and want to reduce withholding on your regular paychecks to offset it, you can do that — but be careful not to underwithhold so much that you owe a penalty when you file.

How to estimate your actual tax on a bonus

To figure out roughly what you will actually owe in federal income tax on a bonus, add the bonus amount to your expected income for the year and use the 2024 tax brackets for your filing status. Your actual rate depends on where that total falls in the brackets, not on a flat 22 percent.

For example, if you are single, your income before the bonus is $60,000, and you receive a $20,000 bonus, your total taxable income is $80,000. Using 2024 brackets, that puts you in the 22 percent bracket, so your federal income tax on the bonus is roughly $4,400 — not $4,400 on the full $80,000. The tax on the first $60,000 is calculated separately at the rates that explore to that portion.

This is an estimate and does not account for deductions, credits, or other income. For a precise number, use tax software or consult a tax professional. But this rough calculation shows you whether your employer's withholding is likely to be close or way off.

Frequently Asked Questions

Is there a tax bracket just for bonuses?

No. Bonuses are taxed at your regular income tax rate based on your total income for the year. The 22 percent withholding rate your employer may use is just a withholding estimate, not your actual tax rate. Your real tax rate depends on your total income and filing status.

Can I avoid taxes on a bonus by putting it in a retirement account?

Not directly. A bonus is wages, and you cannot contribute it to a 401(k) or IRA after you receive it without paying taxes first. However, if your employer allows you to defer part of your bonus into a 401(k) before you receive it, that portion is not subject to federal income tax withholding (though FICA still applies). Ask your payroll department if this option is available.

Why did my bonus withholding seem so high compared to my regular paychecks?

Your employer likely used the aggregate method, which combines your bonus with a regular paycheck and withholds based on the total. Because the combined amount is much larger, the withholding looks steep. This does not mean you owe that much in actual tax — you may get some back as a refund when you file.

Do I have to pay self-employment tax on a bonus?

No. Self-employment tax applies only to income from self-employment or a business you own. If you are an employee receiving a bonus from an employer, you pay FICA taxes (Social Security and Medicare), not self-employment tax. Your employer withholds FICA from your bonus just as they do from your salary.

What if my bonus pushed me into a higher tax bracket?

The U.S. uses a progressive tax system, so only the income in the higher bracket is taxed at the higher rate — not your entire income. If your bonus pushed you from the 22 percent bracket into the 24 percent bracket, only the portion of income above the bracket threshold is taxed at 24 percent. Your employer's withholding may still be inaccurate, but the actual tax is calculated progressively.
