How Are Bonuses Taxed in 2026? Supplemental Wage Rules Explained
You got a $5,000 bonus and only about $3,300 landed in your account. It feels like the government took an outsized cut — and the internet is full of people insisting "bonuses are taxed higher." They're not. Your bonus is taxed at the same rates as the rest of your income. What's different is how much your employer withholds upfront. Understanding that distinction is the key to not overreacting — and to getting money back at tax time.
The myth: bonuses are "taxed higher"
This is the single most common misconception about pay. Your bonus is ordinary income. When you file your return, it's stacked with your wages and taxed at your normal marginal rates — no special "bonus tax" exists. The confusion comes entirely from withholding: the IRS classifies bonuses as "supplemental wages," and employers must withhold federal income tax on them using a special method that often takes out more than your regular paycheck does.
The two withholding methods
Employers can use one of two IRS-approved methods to withhold federal income tax on a bonus:
1. The percentage method (most common)
The bonus is treated separately from your regular pay and withheld at a flat 22% for supplemental wages up to $1 million per year. For any supplemental wages above $1 million in a calendar year, a mandatory 37% rate applies to the excess. This is the method most employers use because it's simple.
2. The aggregate method
The bonus is added to your most recent regular paycheck, and withholding is calculated on the combined total as if that were your normal pay. Because that combined amount can push the calculation into a higher withholding tier, the aggregate method sometimes withholds even more than 22% — though it's later reconciled just the same.
Why your bonus looks so much smaller
The 22% federal income tax withholding is only part of the story. Your bonus is also subject to the same payroll taxes as regular wages:
| Withholding on your bonus | Rate |
|---|---|
| Federal income tax (supplemental) | 22% (flat, up to $1M) |
| Social Security | 6.2% (up to the annual wage base) |
| Medicare | 1.45% (+0.9% above $200k) |
| State income tax (varies) | 0%–10%+ |
| 401(k) / benefits (if elected) | Varies |
Add those up and it's easy to see 30%–40% of a bonus withheld before it hits your account — even though your actual tax rate on that money may be lower. For a deeper breakdown of the payroll taxes, see our Social Security & Medicare taxes guide.
Example: a $5,000 bonus
Federal withholding (22%) = $1,100 · Social Security (6.2%) = $310 · Medicare (1.45%) = $72.50. Before any state tax, roughly $1,482 is withheld, leaving about $3,518. If your true marginal rate is 12%, much of that 22% federal withholding comes back as a refund.
How it all evens out at tax time
Because withholding is just a prepayment, everything is reconciled when you file. If the 22% flat rate withheld more than your actual marginal rate, the excess is refunded. If you're a high earner whose marginal rate is above 22%, the flat withholding may have taken out too little, and you could owe more. Either way, the bonus itself is never taxed at a special rate — it's the withholding that's standardized.
How to keep more of your bonus
You can't change the withholding method your employer uses, but you can reduce the tax you ultimately owe on the bonus:
- Direct it into a 401(k). Many employers let you assign a separate (higher) contribution percentage to bonus checks. Pre-tax contributions reduce your taxable income dollar-for-dollar.
- Fund an HSA if you have a high-deductible health plan — a triple-tax-advantaged way to shelter income.
- Check your W-4. If you consistently get large refunds, your regular withholding may be too high; see our federal withholding guide.
- Plan around deductions — a bonus year can be a good time to make deductible contributions. Our guide to reducing taxes on your paycheck covers the full toolkit.
Frequently asked questions
Are bonuses taxed at a higher rate than regular pay?
No. Bonuses are taxed at ordinary income rates when you file. They only look taxed higher because employers withhold federal tax at a flat 22% supplemental rate, which is often more than your regular paycheck withholding. Over-withholding is refunded at tax time.
What is the federal bonus withholding rate in 2026?
A flat 22% on supplemental wages up to $1 million per year, and a mandatory 37% on the portion above $1 million. These are withholding rates, not final tax rates.
Why was so much taken out of my bonus?
Beyond the 22% federal withholding, your bonus also has Social Security (6.2%), Medicare (1.45%), any state income tax, and elected 401(k)/benefit deductions withheld — easily 30%–40% combined, even if your actual tax owed is lower.
How can I reduce the tax on my bonus?
You can't change the withholding method, but routing the bonus into pre-tax accounts like a 401(k) or HSA lowers the tax you ultimately owe. Any excess withholding comes back as a refund.
