Your bonus is taxed as ordinary income, but the amount withheld depends on how your employer processes it

When you receive a bonus, your employer withholds federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%) from the payment before you see it. The federal income tax withheld is not a fixed percentage — it depends on the method your payroll department uses to calculate it and what you reported on your W-4 form. You may owe more tax when you file your return, or you may get a refund, because bonus withholding is an estimate, not your final tax bill.

The actual tax you owe on a bonus is determined by your total income for the year and your tax bracket, not by the bonus alone. A bonus of $5,000 does not automatically mean $1,000 or $1,500 in taxes — it means your total taxable income rises by $5,000, and the tax on that additional $5,000 depends on what bracket you are in. If you earn $40,000 a year and receive a $5,000 bonus, the bonus pushes you into a higher bracket, and you may owe 22% federal tax on part or all of it. If you earn $150,000 and receive the same bonus, the tax rate on that bonus is higher still.

Key Takeaways

  • Your employer withholds federal income tax, Social Security tax, and Medicare tax from your bonus, but the federal withholding is an estimate based on your W-4, not your final bill.
  • The tax rate on your bonus depends on your total income for the year and your tax bracket, not on the bonus amount alone.
  • Two common withholding methods exist: the percentage method (withholding a flat percentage) and the aggregate method (treating the bonus as part of your regular paycheck for that period).
  • You may owe additional tax or receive a refund when you file your return, because bonus withholding does not account for your full-year income or deductions.
  • Changing your W-4 before you receive a bonus can reduce withholding, but it will not change the actual tax you owe.

The two methods employers use to withhold tax on bonuses

Most employers use one of two approaches. The percentage method withholds a flat percentage — often 22% for federal income tax on bonuses under $1 million, or 37% on bonuses over $1 million. This is straightforward for payroll but often results in too much or too little withheld, depending on your income and deductions.

The aggregate method treats your bonus as if it were part of your regular paycheck for that pay period. Your employer adds the bonus to your normal wages, calculates the tax on the combined amount as though you receive that much every pay period, then subtracts the tax already withheld from your regular paycheck. This method is more accurate but requires more calculation. Some employers default to the percentage method because it is faster.

Ask your payroll department which method they use. If you want to reduce withholding, you can submit a new W-4 before the bonus is paid, but this affects only the withholding calculation — it does not change what you actually owe in tax.

Why your withholding may not match what you actually owe

Bonus withholding is a rough estimate. Your employer does not know your full-year income, whether you have other jobs, what deductions you claim, or whether you have dependents. The withholding also does not account for tax credits you may be may have access to to, such as the Earned Income Tax Credit or child tax credits.

If you are married and both spouses receive bonuses, or if you have side income, the withholding on each bonus is calculated in isolation. You may end up with far more withheld than you owe, or far less. When you file your tax return in April, the IRS compares what was withheld across all your income sources against what you actually owe. If too much was withheld, you receive a refund. If too little was withheld, you owe the difference.

This is why a bonus does not automatically result in a specific tax hit — the real number emerges only when you file your full return and the IRS knows your complete financial picture for the year.

How to estimate your bonus tax before you receive it

To get a rough idea of what you will owe, find out your tax bracket for the year. The 2024 federal tax brackets range from 10% to 37%, depending on your filing status and total income. If you are single and earn $47,000, you are in the 22% bracket. A $5,000 bonus means an additional $1,100 in federal income tax (22% of $5,000), plus 7.65% in Social Security and Medicare taxes ($382.50), for a total of roughly $1,482 in federal and payroll taxes.

However, this is only an estimate. Your actual tax depends on whether you itemize deductions or take the standard deduction, whether you have dependents, and whether you have other income. Use the IRS tax bracket tables for your filing status and income level, then multiply your bonus by the rate shown for your bracket. Add 7.65% for Social Security and Medicare (these rates do not change based on income, though there is an additional 0.9% Medicare tax on income over $200,000 for single filers).

State and local income taxes vary by location. Some states have no income tax; others tax bonuses at rates between 3% and 13%. Check your state's tax website or ask your payroll department what rate applies to you.

What happens if too much or too little tax is withheld

If your employer withholds more tax than you owe, you will receive the overage as a refund when you file your return. This is common with the percentage method, which often over-withholds. You do not lose the money — it is held by the IRS until you file and claim it back.

If too little is withheld, you will owe the difference when you file. If you know this is likely (for example, if you receive a large bonus and are already in a high tax bracket), you can make an estimated tax payment to the IRS before April 15 to avoid a penalty. The IRS charges interest and penalties on unpaid taxes, though the penalty is waived if you paid at least 90% of your current year tax through withholding and estimated payments, or 100% of your prior year tax (110% if your prior year income was over $150,000).

How to adjust your W-4 to change bonus withholding

Your W-4 form tells your employer how much tax to withhold from each paycheck. If you want less withheld from your bonus, you can increase the number of allowances or dependents you claim on your W-4, or you can claim additional income on the form to reduce withholding. Submit the new W-4 to your payroll department before your bonus is paid.

Be cautious: reducing withholding now means you will owe more tax later. This strategy makes sense only if you know you will have a large refund at tax time anyway, or if you are confident you will owe less tax overall. If you reduce withholding and then owe a large amount in April, you may face penalties and interest.

After you receive your bonus, you can adjust your W-4 again to increase withholding for the rest of the year, so the reduction applies only to the bonus period.

Bonuses and self-employment tax if you are a contractor

If you are a contractor or self-employed, you do not receive a bonus in the traditional sense — you invoice for your work and receive payment. However, if you receive a large lump-sum payment for a project, you owe self-employment tax (15.3% combined Social Security and Medicare) on top of federal income tax. You are responsible for calculating and paying this tax yourself, usually through quarterly estimated tax payments. Failure to pay estimated taxes can result in penalties.

If you are unsure whether you are classified as an employee or contractor, check your tax documents. Employees receive a W-2; contractors receive a 1099-NEC or 1099-MISC. The classification determines how your bonus is taxed.

Frequently Asked Questions

Is my bonus taxed differently than my regular paycheck?

No — a bonus is taxed as ordinary income at your regular tax rate. The difference is in how withholding is calculated. Your regular paycheck uses your W-4 to estimate tax; your bonus often uses a flat percentage or aggregate method. The actual tax you owe is the same either way.

Can I avoid paying tax on my bonus?

No. Bonuses are taxable income and must be reported to the IRS. Your employer is required to withhold tax and report the bonus on your W-2. The only legal way to reduce the tax is to claim deductions or credits you are may have access to to when you file your return.

What if my employer withholds 22% but I am in the 12% tax bracket?

You will have overpaid tax, and you will receive the difference as a refund when you file your return. The 22% withholding is an estimate; your actual tax is based on your full-year income and bracket. File your return to claim the refund.

Do I have to pay state tax on my bonus?

Yes, if your state has an income tax. Most states tax bonuses the same way they tax regular income. A few states have no income tax (such as Texas, Florida, and Nevada). Check your state's tax website to find the rate that applies to you.

Will my bonus push me into a higher tax bracket?

It may. Tax brackets are cumulative — as your total income rises, portions of it are taxed at higher rates. A bonus can push you into the next bracket, meaning the bonus itself is taxed at a higher rate than your regular income. This is why a $5,000 bonus does not always result in exactly 22% withholding.
