Your employer withholds federal income tax, Social Security tax, and Medicare tax from a bonus, usually at a flat 22% federal rate or your regular withholding rate—whichever your employer chooses.
When you receive a bonus, your employer must withhold taxes before you see the money. The amount depends on how your company processes the bonus and what tax bracket you're in. Most employers use one of two methods: the percentage method, which withholds a flat 22% in federal income tax, or the aggregate method, which withholds based on your regular paycheck withholding rate. On top of federal income tax, you'll also lose 6.2% to Social Security tax and 1.45% to Medicare tax (or 2.35% if you earn over $200,000 as a single filer).
The exact amount you take home depends on your state income tax, whether you've already hit the Social Security wage cap for the year, and which withholding method your payroll department uses. A $5,000 bonus might result in $3,600 to $3,900 in your pocket after federal, Social Security, and Medicare withholding, but state taxes could reduce that further.
Key Takeaways
- Federal income tax on a bonus is withheld at either a flat 22% or your regular paycheck withholding rate, depending on how your employer processes it.
- Social Security tax (6.2%) and Medicare tax (1.45%) are withheld from bonuses the same way they are from regular paychecks.
- If you've already earned enough to hit the Social Security wage cap earlier in the year, no Social Security tax is withheld from a bonus received later.
- State income tax varies by location and is withheld separately from federal tax, reducing your take-home amount further.
- The total withholding on a bonus is usually 25% to 32% before state taxes, meaning you receive roughly 68% to 75% of the gross amount.
The two federal withholding methods employers use
Your employer chooses between two ways to calculate federal income tax on a bonus. The percentage method is simpler and more common: your company withholds a flat 22% in federal income tax, plus the standard 6.2% Social Security and 1.45% Medicare taxes. This method doesn't account for your personal tax situation—it's the same 22% whether you're in the 12% tax bracket or the 37% bracket.
The aggregate method treats your bonus as if it were part of your regular paycheck. Your payroll department adds the bonus to your next paycheck, calculates what you'd owe in total, then subtracts what was already withheld from earlier paychecks. This method can result in higher or lower withholding depending on your income and how many paychecks you receive per year. If you're in a higher tax bracket, the aggregate method may withhold more than 22%.
You cannot choose which method your employer uses—that's a company decision. However, you can adjust your overall withholding by changing your W-4 form if you expect a large bonus and want to avoid a big tax bill or refund later.
Social Security and Medicare taxes on bonuses
Social Security and Medicare taxes are withheld from bonuses at the same rate as your regular paycheck: 6.2% for Social Security and 1.45% for Medicare. These are payroll taxes, not income taxes, and they explore to almost all wages and bonuses.
One important exception: if you've already earned $168,600 or more in wages during the calendar year (the 2024 Social Security wage base), no additional Social Security tax is withheld from a bonus received later that year. This cap resets on January 1. Medicare tax has no wage cap, so 1.45% is withheld from every bonus, no matter how much you've earned. If you earn over $200,000 as a single filer or $250,000 as a married filer, an additional 0.9% Medicare tax is withheld.
Self-employed people and business owners pay both the employee and employer portion of these taxes (15.3% total), but employees only pay the employee portion through payroll withholding.
How state income tax affects your bonus
Most states withhold income tax from bonuses, but the rate and rules vary widely. Some states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming), so residents in those states skip state withholding entirely. Other states withhold a percentage based on your tax bracket or use a flat rate.
Your employer's payroll system should automatically withhold the correct state tax based on where you live and work. If you live in one state and work in another, your employer withholds based on the state where you work. A few states allow you to claim exemptions or adjust withholding on a state W-4 form, similar to the federal form.
State income tax can add 3% to 13% to your total withholding, depending on where you live. In California, for example, state income tax on a bonus could be 9.3% to 13.3% depending on your income level, stacked on top of the federal withholding.
What happens if too much or too little tax is withheld
If your employer withholds more tax than you actually owe, you'll receive a refund when you file your tax return. This is common with the percentage method, especially if you're in a lower tax bracket or have deductions that reduce your taxable income. The refund arrives months later, so you don't see that money when ready.
If too little tax is withheld, you'll owe money when you file. This can happen if your bonus pushes you into a higher tax bracket or if you have other income sources. You may also owe penalties and interest if you underpaid significantly during the year.
To avoid surprises, you can ask your payroll department which withholding method they're using and estimate your take-home amount. You can also adjust your W-4 before receiving a bonus to increase withholding on your regular paychecks, which gives you more control over the final amount owed or refunded.
Bonuses paid in different ways and their tax treatment
Most bonuses are paid as cash added to your paycheck, and those are subject to the withholding rules above. However, some companies offer bonuses in other forms, and the tax treatment differs slightly.
Stock bonuses and restricted stock units (RSUs) are taxed when they vest or are released to you. Your employer withholds taxes based on the fair market value of the stock on the vesting date, using the same percentage or aggregate method. You may owe additional tax when you sell the stock later if its value has changed.
Signing bonuses for new employees are treated as regular wages and subject to the same withholding as any other bonus. Referral bonuses are also taxed as wages. Gift cards or merchandise bonuses under $25 per year per employee may be excluded from taxable wages in some cases, but this depends on IRS rules and your company's policy—ask your payroll department if you're unsure.
How to estimate your take-home bonus amount
To get a rough estimate of what you'll receive, start with your gross bonus and subtract the taxes you know will be withheld. Federal income tax is usually 22% (or your regular withholding rate), Social Security is 6.2%, and Medicare is 1.45%. That's 29.65% before state tax.
If you live in a state with income tax, add that percentage. For example, a $10,000 bonus in a state with 5% income tax would be taxed at roughly 34.65%, leaving you with about $6,535. In a state with no income tax, you'd keep roughly $7,035.
This is an estimate only—your actual withholding may differ if your employer uses the aggregate method, if you've hit the Social Security wage cap, or if you have other deductions or credits. Your payroll department can give you a more precise number if you ask them to calculate it before the bonus is paid.
Frequently Asked Questions
Can I avoid taxes on a bonus?
No. Bonuses are considered wages and are subject to federal income tax, Social Security tax, and Medicare tax. State income tax also applies in most states. Your employer is required by law to withhold these taxes before paying you. You cannot opt out of withholding, though you can adjust how much is withheld on your regular paychecks by changing your W-4.
Why is my bonus taxed more than my regular paycheck?
It may not be. The percentage method withholds a flat 22% in federal income tax on bonuses, which is often higher than the withholding on a regular paycheck if you're in a lower tax bracket. However, the aggregate method may result in lower withholding. The difference is usually resolved when you file your tax return—if too much was withheld, you get a refund; if too little, you owe the difference.
What if I receive my bonus late in the year?
The timing doesn't change how the bonus is taxed. However, if you've already earned enough to hit the Social Security wage cap, no Social Security tax is withheld from a late-year bonus. Medicare tax is still withheld. Federal and state income tax are withheld the same way regardless of when you receive the bonus.
Do I have to report my bonus on my tax return?
Your employer reports your bonus on your W-2 form as part of your total wages. You don't need to report it separately—it's already included in the W-2 your employer sends to you and the IRS. When you file your tax return, the W-2 information is used to calculate your final tax owed or refund.
Can I claim my bonus as a deduction?
No. Bonuses are income, not deductions. However, if you're self-employed and receive a bonus from a business you own, different rules may explore. For employees, bonuses cannot be deducted from your taxable income.
