Understanding Bonus Taxation
A bonus is supplemental compensation that employers provide to employees in addition to their regular salary. These can include performance incentives, holiday bonuses, signing bonuses, and retention bonuses.
Federal Tax Withholding Methods
The IRS considers bonuses as "supplemental wages" and allows for two different withholding methods:
1. Percentage Method
The most common approach is the flat-rate withholding method:
- 22% flat withholding rate for amounts up to $1 million
- 37% tax rate for amounts over $1 million
2. Aggregate Method
This method combines your bonus with your regular paycheck and withholds taxes based on IRS withholding tables. This might result in higher withholding if the combined amount pushes you into a higher tax bracket temporarily.
Additional Tax Considerations
Bonuses are subject to several other taxes:
- Social Security Tax: 6.2% up to the wage base limit
- Medicare Tax: 1.45% on all earnings
- Additional Medicare Tax: 0.9% for high-income earners
- State and Local Taxes: Vary by location, for example:
- California: 10.23% flat withholding rate
- New York: 9.62% flat rate
- Some states have no income tax
Example Calculation
Annual Salary: $75,000
Bonus: $5,000
Basic withholding breakdown:
- Federal Income Tax: 22% of $5,000 = $1,100
- Social Security Tax: 6.2% of $5,000 = $310
- Medicare Tax: 1.45% of $5,000 = $72.50 Total taxes withheld: $1,482.50
Strategies to Manage Bonus Taxation
To optimize your bonus taxation:
-
Timing Considerations
- Consider receiving the bonus in January instead of December
- Especially beneficial if expecting a lower tax bracket next year
-
Tax Impact Reduction
Contributing to tax-advantaged accounts like 401(k)s or HSAs can help offset the tax impact of receiving a bonus.
- Additional Options
- Increase 401(k) contributions
- Make HSA contributions
- Contribute to a traditional IRA
- Increase charitable donations
- Adjust withholding on regular paychecks
Special Considerations
