Bonuses can be one of the most satisfying parts of your paycheck but they also create confusion when tax time comes around. Many workers are surprised when their bonus appears to be “taxed more” than their regular wages. In reality, bonuses follow specific IRS rules for supplemental wages, and understanding those rules can help you plan, reduce surprises, and keep more of what you earn.
This article breaks down exactly how bonuses are taxed in 2026, including federal withholding rates, FICA taxes, state rules, and strategies to minimize your tax bill.
What Counts as a Bonus?
The IRS classifies bonuses as supplemental wages, which include any compensation paid in addition to regular wages. This category includes:
- Performance bonuses
- Holiday bonuses
- Signing bonuses
- Commission payouts
- Retroactive pay increases
- Severance pay
Because bonuses fall under supplemental wage rules, employers must follow specific federal withholding methods.
Federal Bonus Tax Withholding Rates for 2026
For 2026, the IRS requires employers to withhold federal income tax from bonuses at one of two rates:
- 22% flat rate for bonuses up to $1 million per employer per year
- 37% flat rate for any bonus amount over $1 million
These rates apply when the bonus is paid separately from regular wages or clearly identified as a bonus. They remain unchanged from prior years.
Why Your Bonus Feels “Overtaxed”
The 22% or 37% withholding rate is not your actual tax rate it’s just the amount withheld upfront. Your true tax liability is calculated when you file your return. If your marginal tax bracket is lower than 22%, you’ll get money back. If it’s higher, you may owe more.
Two Ways Employers Tax Bonuses
Employers can choose between two IRS‑approved methods for withholding taxes on bonuses.
1. Flat‑Rate Method (Most Common)
Under this method, your employer withholds:
- 22% federal income tax (or 37% over $1M)
- 6.2% Social Security tax (until you hit the $184,500 wage cap for 2026)
- 1.45% Medicare tax
- 0.9% Additional Medicare Tax if your total wages exceed $200,000 (single) or $250,000 (married filing jointly)
This method is simple and predictable, which is why most employers use it and helps understand how bonuses are taxed.
2. Aggregate Method (Often Higher Withholding)
If your employer combines your bonus with your regular paycheck, the IRS requires them to:
- Add the bonus to your normal wages
- Withhold taxes based on your regular income tax bracket using IRS Publication 15‑T tables
This often results in higher withholding, especially if the combined amount pushes you into a higher bracket for that pay period.
FICA Taxes Apply to All Bonuses
In addition to federal income tax withholding, bonuses are subject to:
- 6.2% Social Security tax (up to the 2026 wage base of $184,500)
- 1.45% Medicare tax (no wage cap)
- 0.9% Additional Medicare Tax for high earners
These payroll taxes apply even if you defer your bonus into a 401(k).
State Taxes on Bonuses
Most states with income tax also apply a supplemental withholding rate to bonuses. Some use a flat rate, while others use their standard income tax brackets.
Eight states plus New Hampshire for wage income do not tax bonuses at all.
Example: How a $10,000 Bonus Is Taxed
Using the flat‑rate method:
- Federal withholding (22%): $2,200
- Social Security (6.2%): $620
- Medicare (1.45%): $145
- Total withheld (before state tax): $2,965
- Take‑home bonus: $7,035
Your actual tax owed may be lower or higher depending on your tax bracket.
Why Bonuses Can Create Tax Surprises
Many employees feel like their bonus is “taxed at 40%,” but this is usually due to:
- High withholding rates (22% + FICA + state tax)
- The aggregate method pushing them into a higher bracket
- Additional Medicare Tax for high earners
- Under‑withholding if their true bracket exceeds 22%
These factors affect withholding, not your final tax bill.
How to Reduce Taxes on Your Bonus
While you can’t avoid taxes entirely, you can reduce withholding or lower your final tax liability.
1. Increase 401(k) or HSA Contributions
If your employer allows bonus deferrals:
- 401(k) contributions reduce federal and state income tax withholding
- FICA taxes still apply
- HSAs reduce taxable income if made through payroll
2. Adjust Your W‑4 Before the Bonus
If you know a bonus is coming, you can temporarily:
- Increase allowances
- Reduce additional withholding
- Update filing status
This helps avoid over‑withholding.
3. Time Your Bonus Strategically
If you’re close to the Social Security wage cap, receiving a bonus after you exceed the $184,500 limit avoids the 6.2% Social Security tax.
4. Check Your State’s Supplemental Rate
Some states allow you to adjust withholding or claim exemptions.
