Bonuses are taxed at a higher rate because of how your employer withholds tax, not because the government charges you more

When you receive a bonus, your employer must withhold federal income tax from it. The IRS allows two methods: the percentage method and the aggregate method. Most employers use the percentage method, which treats the bonus as a separate payment and withholds a flat 22 percent for federal income tax (or 37 percent if the bonus exceeds $1 million). Your regular paycheck uses a different calculation based on your W-4 form and pay frequency, which usually results in lower withholding. This difference in withholding is why your bonus check looks smaller than you expected.

The withholding amount is not your final tax bill — it is money your employer sends to the IRS on your behalf. When you file your tax return in April, the IRS calculates what you actually owe based on your total income for the year. If too much was withheld from your bonus, you get a refund. If too little was withheld, you owe more. The bonus itself is not taxed at a higher rate; it is straightforward withheld at a higher rate upfront.

Key Takeaways

  • Your employer withholds 22 percent from most bonuses automatically, while regular paychecks use withholding based on your W-4 form, which is usually lower.
  • The withholding rate on a bonus is not your final tax rate — it is just money sent to the IRS in advance of your tax return.
  • Bonuses are added to your regular income and taxed at your normal tax bracket, the same as any other money you earn.
  • If your employer uses the aggregate method instead, your bonus may be taxed at a lower rate because it is combined with your regular paycheck for withholding purposes.
  • You can adjust your W-4 before receiving a bonus to reduce withholding, though this requires planning and carries the risk of owing money at tax time.

How the percentage method creates the appearance of higher taxation

Under the percentage method, your employer withholds a flat 22 percent from your bonus check. This happens regardless of your actual tax bracket. If you earn $50,000 per year and receive a $10,000 bonus, your employer withholds $2,200 from the bonus. Your regular paycheck, by contrast, might have only 12 percent withheld because your W-4 reflects your actual tax situation.

The 22 percent withholding is a default rate set by the IRS. It is not tied to your income level, filing status, or deductions. This is why the bonus feels heavily taxed — the withholding is aggressive and one-size-fits-all. However, this is withholding, not taxation. Your actual tax liability depends on your total income for the year, not on the withholding rate your employer chose.

Your actual tax bracket does not change when you receive a bonus

Bonuses are taxed at your marginal tax rate, which is the same rate applied to every dollar you earn. If you are in the 22 percent federal tax bracket, your bonus is taxed at 22 percent — the same as your salary. The difference is that your employer withholds 22 percent when ready, while your regular paycheck withholding is calculated differently.

Some people believe bonuses push them into a higher tax bracket. This is not how tax brackets work. The U.S. uses a progressive tax system: each dollar you earn is taxed at the rate for that bracket, and earning more money does not increase the tax rate on money you already earned. A $10,000 bonus might push some of your income into a higher bracket, but only the portion that crosses the threshold is taxed at the new rate. The rest remains at your current rate.

For example, if you earn $45,000 and are in the 12 percent bracket, and you receive a $10,000 bonus, the first $10,550 of your bonus stays in the 12 percent bracket (assuming 2024 single filer limits). The remaining $4,450 moves into the 22 percent bracket. You do not pay 22 percent on the entire bonus.

The aggregate method can result in lower withholding on bonuses

Some employers use the aggregate method instead of the percentage method. Under this approach, your bonus is combined with your regular paycheck for that pay period, and withholding is calculated on the total. This often results in lower withholding on the bonus because it is treated as part of your normal income stream.

If your employer offers a choice, the aggregate method typically produces a result closer to your actual tax liability. However, most employers default to the percentage method because it is simpler to administer. You can ask your payroll department which method they use and whether you can request the aggregate method instead.

Adjusting your W-4 before bonus season can reduce withholding

If you know a bonus is coming, you can submit a new W-4 form to your employer before you receive it. On the form, you can claim additional deductions or adjust your withholding to reduce the amount taken from your paycheck and bonus. This lowers the withholding on your bonus without changing the withholding on your regular pay.

This strategy carries a risk: if you reduce withholding and do not earn enough to offset it, you may owe money when you file your tax return. You would need to increase withholding again after the bonus to avoid underpayment penalties. The IRS charges interest and penalties if you do not withhold enough throughout the year. For this reason, many people leave withholding as is and accept the refund when they file.

What happens when you file your tax return

When you file your federal tax return, the IRS adds up all the money you earned during the year, including your bonus. It calculates your total tax based on your income, filing status, and deductions. It then subtracts all the withholding your employer sent in — from both regular paychecks and bonuses. If withholding exceeds what you owe, you receive a refund. If withholding is less than what you owe, you pay the difference.

This is why the high withholding on your bonus is often temporary. Many people who receive a bonus and see a large amount withheld end up with a refund in April because their total tax liability for the year is lower than the combined withholding from all paychecks and bonuses.

State and local taxes on bonuses follow similar rules

State income tax withholding on bonuses varies by state. Some states use a flat withholding rate similar to the federal percentage method. Others require employers to withhold based on the employee's W-4 form. A few states have no income tax at all. Local taxes, where they exist, follow similar patterns.

The total withholding on your bonus — federal, state, and local combined — can be substantial. However, the same principle applies: withholding is not your final tax bill. When you file your state and local returns, any excess withholding is refunded to you.

Frequently Asked Questions

Do bonuses get taxed at a different rate than my salary?

No. Bonuses are taxed at your marginal tax rate, the same as your salary. The difference is in withholding: your employer withholds 22 percent from most bonuses automatically, while regular paychecks use withholding based on your W-4 form. This creates the appearance of higher taxation, but your actual tax rate is the same.

Will my bonus push me into a higher tax bracket?

A bonus can push some of your income into a higher bracket, but only the portion that crosses the threshold is taxed at the new rate. The rest remains at your current rate. For most people, the effect is small — a few hundred dollars on a typical bonus.

Can I get the withholding on my bonus reduced?

You can ask your payroll department to use the aggregate method instead of the percentage method, which often results in lower withholding. You can also submit a new W-4 form to reduce withholding before the bonus arrives. However, reducing withholding increases the risk that you will owe money at tax time.

Why do I get a refund after receiving a bonus?

Your employer withholds 22 percent from your bonus, but your actual tax rate may be lower. When you file your tax return, the IRS calculates what you truly owe and refunds any excess withholding. This is common when bonuses are large relative to your annual income.

Is the withholding on my bonus final?

No. Withholding is money your employer sends to the IRS on your behalf. Your final tax bill is determined when you file your tax return. If too much was withheld, you get a refund. If too little was withheld, you owe the difference.
