How Bonus Taxes Work
Bonuses are considered supplemental wages by the IRS and are subject to different withholding rules than regular wages. Employers have two options for calculating federal tax withholding on bonuses: the percentage method and the aggregate method.
Percentage Method (Flat Rate)
Under the percentage method, the IRS allows employers to withhold a flat 22% on bonus amounts up to $1 million. For bonus amounts exceeding $1 million, the rate increases to 37% on the excess. This is the simplest method and the one most commonly used by employers. It is also the default method in this calculator.
Aggregate Method
With the aggregate method, the employer adds the bonus to your regular paycheck and withholds income tax based on your W-4 elections and total income for that pay period. This method can result in higher or lower withholding depending on your income level, filing status, and other factors. It more accurately reflects your marginal tax rate but can sometimes lead to over-withholding.
Net Bonus = Gross Bonus − Federal Tax − State Tax − FICA
Federal Tax = Gross Bonus × Federal Rate • FICA = Gross Bonus × 7.65% • State Tax = Gross Bonus × State Rate
Key Tax Components
1
Federal Income Tax: Withheld at a flat 22% for bonuses up to $1M (percentage method). For the aggregate method, the bonus is combined with regular wages and taxed at your marginal rate based on W-4.
2
FICA (7.65%): Always applies to bonus payments. This consists of 6.2% for Social Security (up to the annual wage base, $176,100 in 2026) and 1.45% for Medicare (no cap, plus an additional 0.9% for high earners above $200K).
3
State Income Tax: Varies by state. Nine states have no income tax (AK, FL, NV, NH, SD, TN, TX, WA, WY). Other states range from ~1% to ~13.3%. Check your state's tax rate for supplemental wages.
4
Local Taxes: Some cities and counties (e.g., New York City, Philadelphia) impose additional local income taxes that may also apply to bonus income.
Percentage vs. Aggregate: Which Is Better?
✅ Percentage Method
Simpler and more predictable. Withholds exactly 22% (or 37% over $1M). Good for one-off or irregular bonuses. May under-withhold if you're in a higher marginal tax bracket.
🔄 Aggregate Method
More accurate for tax liability. Withholds based on your actual W-4 elections and total earnings. Better for regular bonuses paid with each paycheck. May over-withhold for large bonuses.
📋 Year-End True-Up
Regardless of the method used, when you file your annual tax return, the actual tax due is calculated based on your total income. Any over-withholding is refunded, and under-withholding is paid.
⚖️ Employer Choice
Your employer decides which method to use. You can request a specific method, but the employer is not required to accommodate the request. Check with your payroll department.

IRS Guidelines
Based on current IRS rules for supplemental wage withholding. Flat 22% federal rate for bonuses up to $1M and 37% above $1M.
When you receive a bonus from your employer, it's treated as supplemental wage by the Internal Revenue Service (IRS). Supplemental wages include bonuses, commissions, overtime pay, severance pay, back pay, awards, prizes, and other payments that aren't part of your regular wages. The IRS provides specific rules for how employers must withhold taxes on these payments.
The most common approach is the percentage method, where employers withhold a flat 22% for federal income tax on bonuses up to $1 million. For amounts exceeding $1 million, the rate increases to 37% on the excess. This flat-rate approach makes bonus tax calculations straightforward and predictable.
However, the actual tax you owe on your bonus at the end of the year depends on your total income and tax bracket — not just the withholding rate. If you're in a lower tax bracket, you may get some of the withholding back as a refund. If you're in a higher bracket, you may owe additional tax when you file your return.
Percentage Method vs. Aggregate Method
The percentage method is simpler and more commonly used. Your employer withholds a flat 22% of your bonus for federal taxes (37% for amounts over $1M). This ensures consistent withholding regardless of your regular pay frequency or W-4 settings.
The aggregate method treats your bonus as part of your regular paycheck. Your employer adds the bonus to your normal wages and withholds taxes as if the total amount was your regular pay for that period. This can result in higher withholding because the combined amount may push you into a higher withholding bracket for that pay period. The aggregate method is often used when bonuses are paid on the same cycle as regular wages.
Regardless of which method your employer uses, you'll reconcile the total tax when you file your annual tax return. Any excess withholding is refunded, and any shortfall must be paid. This is why understanding your bonus tax situation is important — it helps you plan for potential tax bills or refunds.
Understanding Your Bonus Tax Results
Our Bonus Tax Calculator breaks down your bonus into five clear components. Here's what each one means:
🏛️ Federal Income Tax
Withheld at the IRS supplemental wage rate. For the percentage method, this is a flat 22% on bonuses up to $1 million and 37% on amounts above $1 million. Federal tax is the largest deduction from your bonus.
🏛️ State Income Tax
Varies by state. Nine states (AK, FL, NV, NH, SD, TN, TX, WA, WY) have no state income tax. The rest range from about 1% to 13.3%. Some states also have specific rules for supplemental wages.
🛡️ FICA (Payroll Tax)
A flat 7.65% consisting of 6.2% for Social Security and 1.45% for Medicare. Social Security tax only applies up to the annual wage base limit ($176,100 in 2026). High earners may also owe an additional 0.9% Medicare surtax.
🎯 Net Bonus
Your actual take-home bonus after all taxes are withheld. This is the amount that will be deposited into your bank account. Use this number for your financial planning.
Frequently Asked Questions
What is the federal tax rate for bonuses?
For the percentage method, the IRS requires employers to withhold a flat 22% on bonus amounts up to $1 million. Any amount above $1 million is withheld at 37%. This is the most common method used by employers. For the aggregate method, the bonus is added to your regular wages and taxed at your marginal rate based on your W-4 elections.
Do I get bonus taxes back at tax time?
It depends. The 22% flat rate is a withholding rate, not necessarily your actual tax rate. When you file your annual tax return, your bonus is added to your total income and taxed at your marginal tax rate based on your total taxable income and filing status. If your effective tax rate is lower than 22%, you'll receive a refund for the difference. If it's higher, you may owe additional tax. For example, if your total income puts you in the 12% marginal bracket, you'd get back about 10% of your bonus as a refund.
Is FICA always deducted from bonuses?
Yes, FICA taxes (7.65%) apply to bonus payments just like regular wages. This includes 6.2% for Social Security (up to the annual wage base of $176,100 in 2026) and 1.45% for Medicare (uncapped). If your year-to-date earnings plus the bonus exceed the Social Security wage base, the 6.2% portion stops applying for the remainder of the year. Additionally, high earners (single filers earning over $200,000 or joint filers earning over $250,000) may owe an additional 0.9% Medicare surtax.
What's the difference between the percentage method and aggregate method?
The percentage method applies a flat 22% withholding rate to your bonus independently of your regular pay. It's simpler and more predictable. The aggregate method combines your bonus with your regular wages for that pay period and withholds taxes on the total amount based on your W-4. The aggregate method may result in higher withholding because the combined income can push you into a higher withholding bracket. Your employer chooses which method to use. You can ask your payroll department which method they use for bonus payments.
Which states have no tax on bonuses?
Nine states have no state income tax at all: Alaska, Florida, Nevada, New Hampshire (no tax on wages, but taxes interest and dividends), South Dakota, Tennessee, Texas, Washington, and Wyoming. In these states, your bonus is only subject to federal tax and FICA. Additionally, some states like California, Hawaii, New Jersey, New York, and Oregon have relatively high state income tax rates (8–13.3%) that significantly reduce your net bonus. Use the state tax rate input in our calculator to model your specific situation.
Can I change how my employer withholds taxes on my bonus?
You can request a specific withholding method, but your employer is not required to accommodate the request. However, you can adjust your W-4 form to have additional taxes withheld or claim specific deductions that may affect the aggregate method calculation. If you're concerned about under-withholding, you can make estimated tax payments directly to the IRS. Alternatively, if you expect over-withholding, you can reduce your regular paycheck withholding to compensate. Consult a tax professional for personalized advice on managing your bonus tax situation.
