What Is Bonus Pay?
Bonus pay is additional compensation provided on top of your regular salary. Employers offer bonuses for various reasons:
- Performance bonuses: Rewards for meeting goals
- Year-end/holiday bonuses: Seasonal or annual incentives
- Signing bonuses: Offered to new hires
- Spot bonuses: Instant recognition for great work
- Profit-sharing bonuses: Based on company performance
- Retention bonuses: To retain key employees
While bonuses are exciting, they often come with a surprising tax bite.
Why Is My Bonus Taxed More Than My Regular Pay?
Bonuses are classified as supplemental wages by the IRS, meaning they’re taxed differently than your standard paycheck. Employers generally choose between two withholding methods:
1. The Percentage Method (Flat Rate)
- A flat 22% federal tax is withheld on bonuses up to $1 million.
- Bonuses above $1 million are taxed at 37%.
- This method is simple but doesn’t reflect your actual tax bracket.
Example: A $10,000 bonus will have $2,200 withheld (22%) for federal taxes.
2. The Aggregate Method
- Your bonus is added to your regular paycheck and taxed as one sum.
- This method can result in higher withholding, especially if it temporarily pushes you into a higher bracket.
Example: If your regular monthly pay is $5,000 and your bonus is $3,000:
- Taxes are calculated as if your pay is $8,000.
- The difference between regular and adjusted withholding is applied to your bonus.

Other Factors That Affect Your Bonus Pay
Federal Income Tax Bracket
While the withholding might be 22%, your actual tax rate depends on your total annual income. A lower tax bracket could lead to a refund; a higher bracket may mean more taxes due later.
State Income Taxes
States vary widely. Some have no income tax (e.g., Florida, Texas), while others (like California and New York) can exceed 10%. Your state matters.
FICA Taxes
- Social Security: 6.2% on income up to $168,600 (2024)
- Medicare: 1.45% on all income + 0.9% surtax on high earners
Pre-Tax Deductions
Your bonus may or may not be subject to pre-tax deductions such as:
- 401(k) contributions
- Health insurance premiums
- HSA/FSA contributions
Some employers allow deductions from bonus pay—others don’t.
Strategies to Maximize Your Bonus Pay
1. Timing Your Bonus
- Delay to Next Year: If you expect lower income next year, you could fall into a lower tax bracket.
- Pay Period Planning: Timing your bonus during a low-tax month may reduce withholding under the aggregate method.
2. Increase 401(k) Contributions
- Defer bonus income into your 401(k) to reduce taxable income
- 2024 contribution limits: $23,000 (+$7,500 catch-up for 50+)
3. Adjust Your W-4
Update your W-4 to reflect expected bonuses, preventing over- or under-withholding.
4. Contribute to Tax-Advantaged Accounts
- HSA or FSA contributions can reduce taxable income
- Charitable donations may also yield deductions
Bonus Paycheck Example: Sarah’s $10,000 Bonus
Profile: Sarah, single, lives in California, earns $80,000/year, contributes 6% to her 401(k).
Bonus Amount: $10,000 (percentage method)
| Withholding Type | Amount |
|---|---|
| Federal Tax (22%) | $2,200 |
| State Tax (~10.3%) | $1,030 |
| Social Security (6.2%) | $620 |
| Medicare (1.45%) | $145 |
| 401(k) Contribution | $0 |
| Net Bonus | ~$6,005 |
Her take-home pay that month: ~$10,262 (salary + bonus after tax).
FAQs: Bonus Pay and Taxes
Do bonuses get taxed more than regular pay?
Not exactly. They’re withheld differently, not taxed at a higher rate overall.
Can I ask my employer to use a specific tax method?
It depends on company policy. Some may allow it—ask your payroll department.
Will a bonus push me into a higher tax bracket?
Possibly, but only the portion above each bracket is taxed at the higher rate.
Can I defer my entire bonus into a 401(k)?
Yes—up to the contribution limit. This reduces taxable income, but FICA taxes still apply.
How do I estimate taxes if I receive multiple bonuses?
Use the calculator for each one. Each bonus is typically taxed independently.
