How Much Tax Will You Pay on a Bonus in the USA?
In the United States, bonuses are usually taxed using a flat 22% federal withholding, plus Social Security (6.2%), Medicare (1.45%), and state income tax (if applicable).
As a result, most employees take home 65% to 75% of their bonus amount. However, this is only withholding—your final tax may be lower (or higher) when you file your tax return.
What Is a Bonus in the United States?
In the United States, a bonus is any form of compensation paid in addition to your regular salary or wages. Employers use bonuses to reward performance, retain employees, or provide incentives tied to company or individual goals.
Common types of bonuses include:
- Performance bonuses
- Annual or year-end bonuses
- Signing bonuses
- Referral bonuses
- Retention bonuses
- Commission-based bonuses
- Spot or incentive bonuses
Although bonuses feel like “extra income,” the IRS classifies them as supplemental wages. This classification is why bonuses are often withheld differently than regular paychecks.
Why Are Bonuses Taxed Differently in the USA?
Bonuses are considered irregular income. Unlike normal wages, they may be paid unpredictably and in varying amounts.
To prevent employees from underpaying taxes during the year, the IRS allows employers to use special withholding rules for supplemental wages. These rules are designed for simplicity and consistency—not to increase your final tax burden.
Important: Bonuses are usually withheld at higher rates, but they are not taxed higher overall once your annual return is filed.
How the IRS Classifies Bonus Income
The IRS groups bonuses under Supplemental Wages, which include:
- Bonuses
- Overtime pay
- Commissions
- Severance pay
- Back pay
- Awards and prizes
Because supplemental wages fall outside regular payroll cycles, they are subject to special federal withholding methods.
IRS-Approved Bonus Tax Methods (Explained Simply)
There are two legal methods employers can use to withhold federal tax on bonuses. The method used directly affects how much of your bonus you receive upfront.
Flat Rate Method (Most Common)
Under this method, employers withhold a fixed 22% federal income tax from bonuses up to $1 million.
- Applies to bonuses up to $1,000,000
- Simple and predictable
- Does not depend on your tax bracket
Example:
- Bonus: $5,000
- Federal withholding (22%): $1,100
- Take-home (before FICA & state tax): $3,900
For bonuses above $1 million, the federal withholding rate increases to 37%, which affects only very high earners.
Aggregate Method (Less Common)
With the aggregate method, your employer adds the bonus to your regular paycheck and calculates withholding as if the total were normal wages.
- Bonus is combined with salary
- Taxed using normal tax brackets
- May result in higher temporary withholding
Bonus Tax vs Regular Salary Tax (Key Differences)
| Income Type | Tax Treatment | Withholding Style | Predictability |
|---|---|---|---|
| Regular Salary | Progressive brackets | Based on W-4 | High |
| Bonus | Supplemental wages | Flat or aggregate | Medium |
| Overtime | Supplemental wages | Often aggregated | Medium |
| Commission | Supplemental wages | Flat or aggregate | Medium |

- Federal income tax – withheld using flat or aggregate method

Common Bonus Tax Myths

- “I lose money if my bonus is taxed higher” – False
- “Bonus permanently raises my tax bracket” – False
What Happens to Bonus Tax When You File Your Return?
When you file your tax return, the IRS recalculates your total income and total tax owed. If too much tax was withheld from your bonus, you may receive a refund.
