Bonus payments are taxed as ordinary income, but your employer can withhold taxes using one of two methods that produce different results on your paycheck

When you receive a bonus, the IRS treats it as supplemental wages—money on top of your regular salary. Your employer must withhold federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%) from the bonus itself. The amount withheld depends on which withholding method your employer uses, and this choice affects how much you actually take home.

The two withholding methods are the percentage method and the aggregate method. Under the percentage method, your employer withholds a flat 22% federal income tax on bonuses under $1 million (37% on bonuses over $1 million in a single year). Under the aggregate method, your employer combines your bonus with your regular paycheck and calculates withholding as if all the money were part of one large regular paycheck. The aggregate method often results in less tax withheld because it spreads the bonus across your tax brackets, but it can also result in more withholding depending on your overall income for the year.

Your employer decides which method to use—you do not get to choose. Most employers use the percentage method because it is simpler to calculate. The withholding your employer takes is not the final tax you owe; it is a prepayment toward your actual tax liability, which you settle when you file your tax return.

Key Takeaways

  • Bonuses are taxed as supplemental wages at your ordinary income tax rate, plus Social Security and Medicare taxes.
  • Your employer withholds either 22% federal income tax (percentage method) or calculates withholding based on your total pay for the period (aggregate method).
  • The withholding taken from your bonus is a prepayment; your actual tax owed depends on your total income, deductions, and filing status for the year.
  • If too little tax was withheld, you may owe money when you file your return; if too much was withheld, you receive a refund.
  • State and local taxes on bonuses vary by location and are withheld separately from federal tax.

How the percentage method works

Under the percentage method, your employer withholds a flat 22% of your bonus for federal income tax. This is the most common approach because it requires no calculation beyond multiplying the bonus amount by 0.22. If your bonus is $5,000, your employer withholds $1,100 in federal income tax alone.

In addition to the 22% federal withholding, your employer also withholds 6.2% for Social Security tax and 1.45% for Medicare tax. These are mandatory for all wage earners and do not change based on your income level or filing status. On a $5,000 bonus, that adds another $379 in FICA taxes (Social Security plus Medicare combined), bringing total withholding to $1,479.

The 22% federal rate is a flat withholding amount, not your actual tax bracket. If you are in the 24% or 32% tax bracket, you may owe more tax than was withheld. If you are in the 12% bracket, you may have overpaid and receive a refund when you file. The difference settles when you file your tax return and report all your income for the year.

How the aggregate method works

Under the aggregate method, your employer combines your bonus with your regular paycheck for the pay period and calculates withholding as though the entire amount were regular wages. This method uses your actual tax bracket and can produce a different result than the flat 22% rate.

For example, if you earn $3,000 every two weeks and receive a $5,000 bonus in the same pay period, your employer treats it as $8,000 in wages for that period. Using your W-4 information and the IRS withholding tables, your employer calculates federal income tax on the full $8,000, then subtracts the tax already withheld from your regular paychecks that year. The difference is what gets withheld from your bonus.

The aggregate method can result in less federal withholding than the percentage method if your bonus pushes you into a higher bracket only temporarily. However, it can also result in more withholding if your employer calculates that you have not had enough tax withheld across the year. The outcome depends entirely on your income pattern and tax situation. You will not know the exact amount until you see your pay stub.

State and local taxes on bonuses

In addition to federal tax, most states tax bonuses as ordinary income. State withholding rates vary widely—from 0% in states with no income tax (like Texas, Florida, and Wyoming) to over 10% in high-tax states (like California and New York). Your employer withholds state tax based on the state where you work, not where you live, unless you live in a different state and have filed a nonresident return.

Some cities and counties also impose local income taxes on wages and bonuses. New York City, Philadelphia, and Columbus, Ohio are examples of places with local income tax. If you work in one of these locations, your employer withholds local tax in addition to state and federal tax. The combined withholding can be substantial—in New York City, for instance, combined state and local tax can exceed 10% on top of federal withholding.

If you work in one state but live in another, the rules depend on reciprocal tax agreements between the states. Some states have agreements that allow you to pay tax to your home state instead of your work state. Check your state's tax authority website or ask your employer's payroll department which state tax applies to your bonus.

What happens if withholding does not match what you actually owe

The tax withheld from your bonus is an estimate, not your final bill. When you file your tax return, you report all income earned during the year and calculate your actual tax liability based on your total income, deductions, and filing status. If the total withholding from all your paychecks and bonuses exceeds what you actually owe, you receive a refund. If withholding falls short, you owe the difference.

Bonuses can push you into a higher tax bracket for the year, which means you may owe more tax than your employer withheld. For example, if you earn $60,000 in regular salary and receive a $20,000 bonus, your total taxable income is $80,000. Depending on your filing status and deductions, this combined income might put you in a higher bracket than your regular salary alone would have. The 22% withholding on the bonus might not cover the additional tax you owe on that higher bracket.

Conversely, if you have significant deductions or credits, the withholding might exceed what you owe, and you will receive a refund. The key is that withholding is not final—it is a prepayment that gets reconciled when you file.

How to estimate your bonus tax before you receive it

If you know your bonus amount in advance, you can estimate the tax using the percentage method: multiply your bonus by 0.22 for federal withholding, then add 7.65% for FICA taxes (6.2% Social Security plus 1.45% Medicare). This gives you a rough federal and FICA withholding estimate. For example, a $10,000 bonus would have approximately $2,200 in federal withholding plus $765 in FICA taxes, totaling $2,965 withheld.

To estimate your actual tax liability for the year, use the IRS Tax Withholding Estimator tool on IRS.gov. This tool asks about your income, deductions, credits, and filing status, then tells you whether you are on track to owe, break even, or receive a refund. If the tool shows you will owe money after your bonus, you can adjust your W-4 to have extra tax withheld from future paychecks, or you can plan to pay the difference when you file.

State and local tax estimates depend on your location. Most state tax authority websites have withholding calculators or tables you can use to estimate state tax on supplemental wages. Contact your state's department of revenue or your employer's payroll department for the specific rate that applies to you.

Frequently Asked Questions

Is bonus tax different from regular paycheck tax?

Bonus tax is calculated the same way as regular income tax—it counts as ordinary income subject to federal, state, and local income tax plus FICA taxes. The difference is in how your employer withholds the tax. Regular paychecks use your W-4 withholding allowances; bonuses use either a flat 22% rate or are aggregated with your regular pay. The end result is the same: the tax is withheld upfront and reconciled when you file your return.

Can I avoid paying tax on a bonus?

No. Bonuses are taxable income and cannot be avoided. However, you can reduce your overall tax liability by maximizing contributions to tax-deferred accounts like 401(k)s or traditional IRAs, or by claiming deductions and credits you are may have access to to. These strategies reduce your taxable income for the year, which can lower the tax you owe on your bonus and all other income combined.

What if my employer withheld too much tax from my bonus?

If too much tax was withheld, you will receive a refund when you file your tax return. The refund reflects the difference between what was withheld and what you actually owe based on your total income for the year. You do not need to do anything special—the refund is calculated automatically when you file.

Do I have to report my bonus separately on my tax return?

No. Your bonus is included in your W-2 form under Box 1 (wages, tips, other compensation) along with all your other income from that employer. You report the total amount from Box 1 on your tax return; you do not itemize bonuses separately. The withholding from your bonus appears in Box 2 (federal income tax withheld) along with withholding from all your other paychecks.

What if I receive a bonus from a side job or freelance work?

If the bonus comes from self-employment or a 1099 contractor arrangement, it is not subject to employer withholding. You are responsible for paying self-employment tax (15.3% combined Social Security and Medicare) plus income tax on the full amount. You may need to make quarterly estimated tax payments to the IRS to avoid penalties. Consult a tax professional or use the IRS Estimated Tax Worksheet to calculate what you owe.
