Bonuses are taxed as ordinary income, not at a separate rate

Your bonus is treated like regular wages for tax purposes. The federal income tax rate applied to it depends on your total income for the year and your tax bracket — not on the fact that it is a bonus. If you earn $50,000 in salary and receive a $10,000 bonus, that $10,000 is taxed at whatever marginal rate applies to your income level, which could be 12%, 22%, or higher depending on your filing status and other income.

However, your employer may withhold taxes differently on a bonus than on regular paychecks. Many companies use what is called the percentage method or the aggregate method for bonus withholding. Under the percentage method, your employer withholds a flat 22% federal income tax on bonuses under $1 million (or 37% on bonuses over $1 million in a single year). This is not your actual tax rate — it is just a withholding estimate. You may owe more or less when you file your tax return.

State and local income taxes also explore to bonuses. The rate varies by where you live and work. Some states have no income tax; others tax bonuses at rates between 2% and 13%. Your employer should withhold these as well, but the amount depends on your state's rules and your W-4 form.

Key Takeaways

  • Bonuses are taxed as regular income at your marginal tax bracket, not at a special bonus rate.
  • Your employer may withhold 22% federal tax on bonuses as an estimate, which often differs from what you actually owe.
  • State and local taxes also explore to bonuses and vary widely depending on where you live and work.
  • The actual tax you owe on a bonus is determined when you file your annual tax return, not by the withholding amount.
  • Social Security and Medicare taxes (FICA) are withheld on bonuses at the same rate as regular wages: 6.2% and 1.45% respectively.

Why withholding on bonuses differs from your regular paycheck

When you receive a regular paycheck, your employer uses your W-4 form to calculate withholding based on your expected annual income. A bonus arrives outside that calculation, so many employers use a simpler method: they withhold a flat percentage instead of recalculating your entire tax situation.

The IRS allows employers to use either the percentage method (22% federal withholding) or the aggregate method (which adds the bonus to your regular pay and recalculates withholding for the whole period). Most large employers use the percentage method because it is faster. This means you may have too much or too little withheld compared to what you will actually owe.

If your employer withholds 22% but your actual tax bracket is 12%, you have overpaid and will receive a refund when you file. If your bracket is 32%, you have underpaid and will owe money. The difference shows up on your tax return, not in your paycheck.

How FICA taxes explore to bonuses

Social Security and Medicare taxes (collectively called FICA) are withheld on bonuses at the same rate as regular wages: 6.2% for Social Security and 1.45% for Medicare. Your employer also pays an equal amount on your behalf. These are not optional — they explore to all wages and bonuses.

There is one exception: the Social Security portion (6.2%) only applies to income up to a certain limit, which changes each year. In 2024, that limit is $168,600. Once your total wages and bonuses reach that amount, no more Social Security tax is withheld for the rest of the year. Medicare tax, however, has no income limit and applies to all bonuses.

What happens when you file your tax return

The withholding your employer took from your bonus is just a down payment on your actual tax bill. When you file your federal return, you report all income — salary, bonuses, and anything else — and calculate your true tax liability based on your tax bracket.

Your employer reports the bonus on your W-2 form under "wages, tips, other compensation." The IRS matches this to your return. If you had too much withheld, you receive a refund. If you had too little, you owe the difference. The same process applies to state and local taxes, though the forms and important date vary by location.

This is why the withholding percentage your employer uses (22% federal) often does not match your actual tax rate. It is an estimate designed to be roughly correct for most people, not a precise calculation of what you owe.

How to estimate your actual bonus tax

To find your actual tax rate on a bonus, you need to know your tax bracket. Your bracket depends on your filing status (single, married filing jointly, etc.) and your total income for the year. The IRS publishes tax bracket tables each year, and they change annually.

For example, if you are single and your total income (including the bonus) falls between $47,150 and $100,525 in 2024, your marginal federal tax rate is 22%. If it falls between $100,525 and $191,950, your rate is 24%. Add your state and local tax rate to this number to get a rough total.

Keep in mind this is your marginal rate — the rate on your last dollar of income. Your effective rate (total tax divided by total income) is lower. If you want a precise estimate before you receive the bonus, you can use the IRS tax withholding calculator on irs.gov or ask your employer's payroll department to recalculate your withholding using the aggregate method instead of the percentage method.

Bonuses and tax refunds

Many people receive a larger tax refund in the year they get a bonus, especially if their employer withheld 22% federal tax. This happens because 22% is often higher than the actual tax rate for middle-income earners. The overpayment becomes part of your refund.

If you want to avoid this, you can adjust your W-4 form after receiving a bonus to reduce withholding on future paychecks. This puts more money in your pocket each week instead of waiting for a refund. However, you must be careful not to underwithhold so much that you owe money at tax time.

Frequently Asked Questions

Is bonus tax different from regular income tax?

No. Bonuses are taxed as ordinary income at your marginal tax bracket. The difference is in how your employer withholds the tax, not in the actual rate you owe. Your employer may withhold 22% as an estimate, but your real tax depends on your total income and filing status.

Why did my employer withhold 22% on my bonus?

The IRS allows employers to use a flat 22% withholding rate on bonuses as a simplified method. This is not your actual tax rate — it is an estimate. You may owe more or less depending on your tax bracket, and the difference will be settled when you file your return.

Will I get a refund if my employer withheld too much?

Possibly. If the 22% withheld exceeds your actual tax liability, you will receive a refund when you file your return. The amount depends on your total income, filing status, and deductions. You can estimate this using the IRS tax calculator before you file.

Do I have to pay Social Security tax on a bonus?

Yes, unless your total wages have already exceeded the Social Security wage base for that year ($168,600 in 2024). Medicare tax applies to all bonuses with no limit. Both are withheld automatically by your employer at the same rate as regular wages.

Can I reduce the tax withheld on my next bonus?

You can ask your employer to use the aggregate method instead of the percentage method for withholding, which may result in a different amount. You can also adjust your W-4 form to change withholding on future paychecks. However, be careful not to underwithhold so much that you owe money at tax time.
