Bonuses are taxed as regular income, but your employer may withhold more tax upfront than you'll actually owe
A bonus is treated as wages by the IRS, so it's subject to federal income tax, Social Security tax, and Medicare tax just like your regular paycheck. The difference is not in the tax rate — it's in how much your employer withholds when they hand you the money. Many employers use what's called the percentage method, which withholds a flat 22% (or 37% on bonuses over $1 million) for federal income tax alone. That's often more than you'll actually owe when you file your return in April, which means you may get some of it back as a refund.
The other common approach is the aggregate method, where your employer adds the bonus to your regular paycheck for that period and calculates withholding as if that combined amount is your normal pay. This can result in much higher withholding, because it temporarily bumps you into a higher tax bracket. Either way, the tax is not a penalty — it's an advance payment on the income tax you owe. What you see withheld and what you actually owe are usually two different numbers.
Key Takeaways
- Bonuses are taxed as ordinary income at your regular tax rate, but employers often withhold 22% or more upfront, which is usually more than you'll owe.
- The percentage method withholds a flat 22% for federal income tax; the aggregate method adds the bonus to your regular pay and withholds based on the combined total, often resulting in higher withholding.
- You will owe Social Security tax (6.2%) and Medicare tax (1.45%) on the bonus, plus federal and state income tax, but the exact amount depends on your total income for the year.
- If your employer withholds more than you owe, you'll receive the difference back when you file your tax return, usually in the spring.
- Adjusting your W-4 before receiving a bonus can reduce over-withholding, but you'll need to change it back afterward to avoid under-withholding on future paychecks.
Why withholding on bonuses is often too high
The 22% flat withholding rate exists because the IRS assumes bonuses are one-time payments, not part of your regular income stream. If your employer uses the percentage method, they withhold 22% for federal income tax, plus 6.2% for Social Security and 1.45% for Medicare — totaling about 29.65% before any state tax. For many people, especially those in lower tax brackets, 22% is more than their actual federal income tax rate.
The aggregate method can be even more aggressive. If you earn $3,000 per week and receive a $10,000 bonus, your employer treats that pay period as if you earn $13,000 per week. They calculate withholding as if you earn that amount every week of the year, which pushes you into a higher bracket temporarily. When you file your return and show your actual annual income, you owe less, and the excess withholding comes back to you.
State income tax adds another layer. Some states withhold a percentage of the bonus; others use the aggregate method too. A few states don't tax bonuses at all, or tax them at a different rate than regular wages. Check your state's tax authority website to understand how your state treats bonuses.
How much tax you'll actually owe on a bonus
Your actual tax liability on a bonus depends on your total income for the year, not on the bonus alone. If you're single, earn $50,000 in regular wages, and receive a $5,000 bonus, that bonus is taxed at your marginal rate — the rate that applies to your last dollar of income. For 2024, if you're single, the federal tax rate on income between $47,150 and $100,525 is 22%. So you owe roughly 22% federal income tax on the bonus, plus 6.2% Social Security and 1.45% Medicare, totaling about 29.65% before state tax.
But if your regular wages already put you in the 24% bracket, or if you're married filing jointly and your household income is higher, your marginal rate is different. The only way to know exactly what you owe is to run the numbers on your full-year income when you file your return. That's why the withholding your employer takes out is an estimate — sometimes high, sometimes low, but rarely exact.
Self-employed people and contractors don't have withholding at all. They owe the same income tax plus an additional 15.3% self-employment tax (which covers both the employer and employee portions of Social Security and Medicare). If you're self-employed and receive a bonus-like payment, set aside roughly 25% to 30% for taxes, depending on your bracket.
The difference between the percentage method and aggregate method
| Method | How It Works | Typical Result |
|---|---|---|
| Percentage method | Employer withholds a flat 22% (or 37% on bonuses over $1 million) for federal income tax, plus Social Security and Medicare on the bonus only | Moderate withholding; often results in a refund for lower-income earners |
| Aggregate method | Employer adds the bonus to your regular paycheck and calculates withholding as if that combined amount is your normal pay for the year | Higher withholding; more likely to result in a refund, especially if the bonus is large |
Your employer chooses which method to use, and they're not required to tell you in advance. You can ask your payroll or HR department which method they use, but you cannot force them to switch. The percentage method is simpler and more common for one-time bonuses. The aggregate method is more common for bonuses that are part of a regular pay cycle, like annual performance bonuses paid in December.
What happens if you want to reduce withholding before a bonus
You can adjust your W-4 to reduce federal income tax withholding before you receive a bonus. The W-4 form has a line for "other income" and another for "deductions" — both of which affect how much your employer withholds. If you increase the "other income" line or decrease the "deductions" line, your employer will withhold less from each paycheck. However, this is a temporary fix and requires planning.
The catch is that you must change your W-4 back after the bonus arrives, or you'll under-withhold on future paychecks and owe money at tax time. You can submit a new W-4 to your employer at any time — there's no limit on how many times you can change it. Use the IRS W-4 calculator on irs.gov to figure out what adjustments make sense for your situation. If you're unsure, it's safer to let the withholding happen and claim the refund later; adjusting your W-4 requires you to remember to reverse the change.
How to handle a bonus on your tax return
When you file your tax return, the bonus will already be included in the W-2 your employer sends you in January. The W-2 shows your total wages for the year, including the bonus, and the total federal and state tax withheld. You don't report the bonus separately — it's just part of your total income.
If your employer withheld more tax than you owe, you'll receive a refund. If they withheld less, you'll owe the difference when you file. Most people who receive a bonus and have standard withholding end up with a refund, because the flat 22% withholding rate is usually higher than their actual tax rate.
Keep any bonus documentation your employer gives you, even though you won't need it to file your return. If you're audited, the IRS may ask for proof of the bonus amount and when you received it. Your pay stubs and W-2 are usually enough, but having the original bonus letter or announcement is helpful.
Bonuses and other taxes you might owe
In addition to federal income tax, Social Security tax, and Medicare tax, a bonus may trigger other tax obligations depending on your situation. If you're self-employed or have other self-employment income, a bonus might push you over the threshold for estimated quarterly tax payments. If you're married and both spouses work, a large bonus could affect your combined income and change your tax bracket or phase out certain deductions.
Some states also tax bonuses differently than regular wages. A few states, like Illinois and Pennsylvania, don't tax wages at all but may tax bonuses. Others explore a flat bonus tax rate that's different from the regular income tax rate. Check your state's Department of Revenue or Tax website to see how your state treats bonuses.
If you receive a bonus in the form of stock options, restricted stock units (RSUs), or other non-cash compensation, the tax treatment is different and more complex. Those are taxed when they vest or are exercised, not when you receive them, and the amount you owe depends on the fair market value at the time of vesting. If your employer offers this type of bonus, ask your HR or tax department for guidance specific to your situation.
Frequently Asked Questions
Will I get a refund if my employer withheld too much tax on my bonus?
Yes, if your employer withheld more than you actually owe in federal income tax, you'll receive the excess back when you file your return in the spring. The refund is calculated based on your total income for the year, not just the bonus. You can also adjust your W-4 to reduce withholding on future paychecks, but you'll need to change it back after the bonus to avoid under-withholding.
Is a bonus taxed at a higher rate than my regular paycheck?
No, a bonus is taxed at the same rate as your regular income — your marginal tax rate. The difference is that your employer may withhold more upfront (22% flat, or more under the aggregate method) than you'll actually owe. When you file your return, the bonus is combined with all your other income, and you pay tax based on your total earnings for the year.
What if I'm self-employed and receive a bonus-like payment?
Self-employed income is subject to federal income tax plus self-employment tax (15.3% total for Social Security and Medicare). No withholding happens automatically, so you should set aside 25% to 30% of any bonus-like payment for taxes, depending on your tax bracket. You may also owe estimated quarterly taxes if your income crosses certain thresholds.
Can my employer choose not to withhold taxes on my bonus?
No, your employer is required by law to withhold federal income tax, Social Security tax, and Medicare tax on all wages, including bonuses. They can choose which withholding method to use (percentage or aggregate), but they cannot skip withholding entirely. If they do, you're still liable for the tax, and they could face penalties.
Does a bonus affect my tax bracket for the whole year?
A bonus increases your total income for the year, which may push you into a higher tax bracket. However, only the income in the higher bracket is taxed at the higher rate — your lower income is still taxed at the lower rates. For example, if you earn $50,000 and receive a $10,000 bonus, the first $50,000 is taxed at your regular rate, and only the $10,000 is taxed at the marginal rate for that income level.
