Your bonus is taxed as ordinary income, not at a special rate

The tax on a bonus depends on your total income for the year and your tax bracket, not on the bonus itself. There is no separate "bonus tax percentage" — your employer withholds federal income tax, Social Security tax, and Medicare tax from the bonus check using the same rates that explore to your regular paychecks. The amount withheld is an estimate; your actual tax bill gets settled when you file your return.

Your employer chooses one of two methods to calculate withholding on a bonus. The percentage method treats the bonus as a separate payment and withholds a flat 22% federal income tax (or 37% if your total bonuses for the year exceed $1 million). The aggregate method adds the bonus to your regular paycheck and calculates withholding as if that combined amount were your normal pay for that period. The aggregate method usually results in more accurate withholding because it accounts for your actual tax bracket.

Key Takeaways

  • Federal income tax withholding on a bonus is either a flat 22% or calculated based on your tax bracket, depending on which method your employer uses.
  • Social Security tax (6.2%) and Medicare tax (1.45%) are withheld on bonuses the same way they are on regular pay, with no cap except for Social Security.
  • State and local income taxes vary by location and are withheld separately from federal tax.
  • The amount withheld is an estimate — you may owe more tax or receive a refund when you file your annual return, depending on your total income and deductions.
  • If too little tax is withheld, you can adjust your W-4 form to increase withholding on future paychecks.

Federal income tax withholding on bonuses

When your employer withholds federal income tax from a bonus using the percentage method, they take out 22% if your bonuses for the year total $1 million or less. If your total bonuses exceed $1 million in a calendar year, the amount over $1 million is taxed at 37%. This is a withholding rate, not your actual tax rate — it is meant to be a reasonable estimate for most workers.

The aggregate method works differently. Your employer adds the bonus to your regular paycheck for that period, calculates what the combined payment would be if it happened every pay period, looks up the withholding for that amount in IRS tables, and then subtracts the withholding already taken from your regular paychecks. The result is the withholding on the bonus. This method is more likely to match your actual tax bracket, especially if you earn a high salary or receive a large bonus.

Neither method is wrong — employers choose based on their payroll system and preference. The percentage method is simpler to calculate. The aggregate method is often more accurate. You will see which one was used on your pay stub.

Social Security and Medicare taxes on bonuses

Social Security tax (6.2%) and Medicare tax (1.45%) are withheld from bonuses the same way they are withheld from your regular paycheck. Your employer matches both amounts, so the total cost to them is 7.65% on top of what they pay you.

Social Security tax has a wage base limit — in 2024, you stop paying it once your total wages for the year reach $168,600. If your bonus pushes you over that limit, Social Security tax is withheld only on the portion of the bonus below the cap. Medicare tax has no cap and is withheld on all bonus income. High earners also pay an additional 0.9% Medicare tax on wages over $200,000 (single) or $250,000 (married filing jointly), and this applies to bonuses as well.

State and local income tax on bonuses

Most states that have an income tax withhold it from bonuses at the same rate as regular pay. The rate depends on your state and your income level — some states use a flat rate, others use brackets. A few states have no income tax at all (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming).

Local income taxes exist in some cities and counties, most commonly in Ohio, Pennsylvania, and Kentucky. These are withheld separately and at rates set by the local jurisdiction. If you work in one location but live in another, your employer withholds based on where you work, and you may need to file a local return in your home location when you file your annual taxes.

Why the amount withheld may not equal your actual tax

Withholding is an estimate based on the information on your W-4 form and the assumption that you will earn the same amount every pay period for the rest of the year. A bonus disrupts that pattern, so the withholding calculated using the percentage method (22%) may be too high or too low depending on your actual tax bracket.

If you earn $50,000 per year, your federal tax bracket is 12%, so a 22% withholding on a bonus means too much tax is taken out — you will likely receive a refund when you file. If you earn $200,000 per year, your bracket is 24%, so 22% withholding may be too low, and you may owe additional tax. The aggregate method avoids this problem by calculating withholding based on your actual bracket, but it is not perfect either if your bonus is unusually large.

When you file your annual tax return, the IRS compares all the tax you paid (through withholding and estimated payments) to what you actually owe based on your total income, deductions, and credits. If you paid too much, you get a refund. If you paid too little, you owe the difference.

Adjusting withholding if too little tax is taken out

If you receive a large bonus and expect to owe additional tax, you can increase the federal income tax withholding on your paychecks for the rest of the year. Fill out a new Form W-4 and submit it to your payroll department. On the form, you can request an extra dollar amount to be withheld from each paycheck, or you can adjust your withholding allowances to reflect your expected annual income.

The W-4 has no line for "bonus" — it asks about your total income, other jobs, dependents, and deductions. If you received a bonus and want to account for it, estimate your total income for the year (regular pay plus bonus), and fill out the form as if that is what you will earn. Your payroll department will recalculate withholding based on the new W-4 starting with the next paycheck.

You can also make an estimated tax payment directly to the IRS if you prefer not to adjust your W-4. Use Form 1040-ES to calculate the payment and pay online through IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or by check.

Bonuses and your tax refund or bill

A bonus affects your total income for the year, which can change whether you receive a refund or owe tax. If you were expecting a refund based on your regular salary, a large bonus may reduce that refund or turn it into a bill. Conversely, if you were expecting to owe tax, a bonus increases what you owe.

The withholding on the bonus is credited toward your total tax bill for the year. If the withholding (22% or your bracket rate) is higher than your actual tax rate, you will see a larger refund or smaller bill. If the withholding is lower than your actual rate, your refund will be smaller or your bill will be larger.

You will not know the exact impact until you file your return and calculate your total income, deductions, and credits. Many people use tax software or a tax professional to run scenarios before the bonus is paid, so they know whether to adjust withholding.

Frequently Asked Questions

Is a bonus taxed differently than regular pay?

No. A bonus is taxed as ordinary income using the same tax brackets and rates as your regular paycheck. The only difference is how your employer calculates the withholding estimate — they may use a flat 22% rate or calculate it based on your tax bracket. The actual tax you owe is determined when you file your return.

Can I avoid paying tax on a bonus?

No. Bonuses are income and are subject to federal, state, and local income tax, as well as Social Security and Medicare tax. You cannot exclude a bonus from your income or defer it to a later year unless your employer offers a specific deferred compensation plan, which is rare for regular bonuses.

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

The excess withholding is credited toward your total tax bill for the year. When you file your return, if you paid more tax than you owe, you will receive a refund. You do not need to do anything special — the IRS will calculate the refund automatically.

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

No. Your bonus is included in the total wages reported on your W-2 form, which you report on your tax return as part of your total income. You do not itemize bonuses separately unless you are self-employed or received the bonus from a source other than your employer.

Will a bonus affect my tax credits or deductions?

It may. Some tax credits phase out at higher income levels — for example, the Earned Income Tax Credit and the Child Tax Credit. A bonus that pushes your income above the phase-out threshold will reduce or eliminate those credits. Deductions are not affected by income level, but your total tax bill will be higher because your bonus increases your taxable income.
