Why Your Bonus Looks So Small (It’s Withholding, Not a Higher Tax)

Here’s the reframe that fixes almost all the frustration: the government did not invent a special, punishing tax rate for your bonus. What changed was how much your employer set aside — the withholding — not the tax you ultimately owe.

The IRS calls a bonus a supplemental wage. That’s the same bucket as commissions, severance, back pay, and prizes. Supplemental wages have their own withholding shortcut so payroll systems don’t have to re-run your full W-4 math on an irregular payment. The most common shortcut is a flat 22% held back for federal income tax. But that flat 22% is a placeholder — your actual bonus tax is your ordinary income tax at your marginal rate, and it gets reconciled to the penny when you file.

• 22%Flat federal withholding on most bonuses (up to $1M)
• 37%Withholding on any part of a bonus over $1M in a year
• 7.65%FICA (Social Security + Medicare) on top

The proof that it’s not a higher rate: a $30,000 bonus and $30,000 of extra salary produce the exact same final tax bill. Same income, same brackets, same result on your return. Only the timing and the size of the upfront withholding differ. Because 2026 kept the individual tax rates in place under the law commonly called the One Big Beautiful Bill Act, none of these bonus rules changed this year — you can read the details in our guide to the 2026 OBBBA tax changes.

So if you felt robbed, you probably weren’t. In most cases you were over-withheld, which is annoying in the moment but comes back to you later. Let’s look at why some people see a number that’s even scarier than 22%.

The 2 Withholding Methods (Why Some People See 40%)

Your employer gets to choose between two ways of calculating federal withholding on a bonus. Which one they use is the single biggest reason two coworkers with identical bonuses can see wildly different amounts taken out.

The crucial thing to understand about the aggregate method: it does not raise your annual tax. It just front-loads more withholding on that one check. Everything gets reconciled when you file — if the aggregate method grabbed too much, the excess comes back as a refund. Here’s the same idea in a side-by-side:

Tip: if your pay stub shows the bonus and your salary combined on one check, you were likely aggregated — and any over-withholding will show up as a bigger refund at filing.

What You Actually Keep: A Real Example

Let’s run a clean $10,000 bonus through the flat 22% method in a state with no income tax. This is exactly the math a “bonus tax calculator” runs behind the scenes — no app required.

• $2,200Federal withheld (22% of $10,000)
• $765FICA withheld (7.65% of $10,000)
• $7,035Lands in your pocket

Scale that up or down using the take-home table at the top of this page: find your bonus amount and read across to the green take-home figure. A $5,000 bonus nets about $3,518; a $20,000 bonus nets about $14,070. In a state like California, subtract roughly another 10% for state withholding.

The $1 million rule

If you’re lucky enough to land a truly enormous bonus, the flat rate splits. Say a $1.5 million bonus: the first $1,000,000 is withheld at 22% ($220,000), and the remaining $500,000 is withheld at the mandatory 37% ($185,000) — about $405,000 of federal withholding on that structure before FICA. For nearly everyone, though, the whole bonus sits comfortably under $1M and rides the flat 22%.

The Other Taxes on Your Bonus (FICA + State)

Federal income tax withholding is only one bite. Two others show up on the same stub, and they’re the same taxes you pay on regular wages — a bonus isn’t singled out here either.

• 6.2%Social Security (OASDI), up to the 2026 wage cap of $184,500
• 1.45%Medicare on all wages (plus 0.9% over $200,000)
• VariesState income tax — from 0% to double digits

Together, Social Security and Medicare make up FICA, about 7.65% of your bonus. If you see “OASDI” on your pay stub, that’s just the official name for the Social Security portion. Once your total wages for the year cross the $184,500 Social Security cap, that 6.2% stops for the rest of the year — Medicare keeps going with no cap.

State tax is where things really diverge. Some states apply a dedicated supplemental withholding rate to bonuses, some tax them at their ordinary wage rate, and nine states don’t tax wage income at all — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — so there’s no state bite on a bonus earned there. A representative sample:

State rules change often, and city taxes can apply on top. Confirm the current figure with your own state’s department of revenue before relying on it.

Do You Get the Bonus Tax Back?

This is the part almost nobody explains, and it’s the whole ballgame. That 22% is a prepayment, not your final tax. When you file, the IRS adds your bonus to the rest of your income, calculates the real tax at your marginal rate, and compares it to everything that was withheld all year. If too much was held back, the difference comes back to you.

So the honest answer to “do I get my bonus tax back?” is: it depends on your bracket. Most workers sit in the 10%–22% range, which is why over-withholding — and a refund — is the common experience. If you’re a higher earner, the flat 22% is often less than your real rate, so brace for a bill rather than a refund. Curious when a refund actually lands? See our 2026 tax refund schedule.

How to Keep More of Your Bonus

Set expectations first: you cannot change the tax rate on a bonus. It’s ordinary income at your marginal rate, full stop. What you can do is lower the taxable income it lands on, or fix your withholding so surprises stop happening. A few honest levers:

1. Route it into a traditional 401(k) or HSA. Many employers let you direct a bonus (or a percentage of it) straight into your retirement plan, which lowers your taxable income for the year. Mind the annual caps — see our 2026 401(k) contribution limits and how HSAs work as a tax-free wealth tool.
2. Defer it to a lower-income year if your employer offers timing flexibility — pushing a December bonus to January can matter if you expect to earn less next year or you’re near a bracket edge.
3. Fix your W-4 if bonuses routinely leave you owing. Adjusting withholding won’t change your total tax, but it smooths out the surprises.
4. Don’t overlook everyday deductions that shrink your taxable income more broadly — our checklist of commonly missed deductions is a good sweep.

One reframe worth keeping: a bonus is ordinary income, unlike long-term capital gains, which get their own lower rates. There’s no magic bracket for bonuses to fall into — only taxable income to reduce and withholding to true up.

Bonus vs. Raise: Which Is Better?

People often assume a raise is smarter “for tax reasons.” On the final tax bill, there’s no difference — a raise and a bonus are both ordinary income taxed at your marginal rate. The real trade-off is about certainty and long-term value, not a tax trick.

A raise is permanent: it lifts every future paycheck, compounds into future raises, and often raises your 401(k) match and eventual salary offers elsewhere. A bonus is a one-time payment that isn’t guaranteed to repeat. If you can choose, weigh a smaller-but-permanent raise against a larger-but-one-time bonus on lifetime value — the tax treatment shouldn’t be the deciding factor.

3 Bonus Tax Myths

• ❌ Myth: “Bonuses are taxed at a higher rate than my salary.”

  ✅ Reality: Same ordinary tax rates as any wages. Only the upfront withholding differs — a flat 22% shortcut instead of your W-4 math.

• ❌ Myth: “Bonuses get taxed twice.”

  ✅ Reality: No. A bonus faces one income tax plus normal FICA — exactly like your regular paycheck. There’s no double tax.

• ❌ Myth: “That 40% they took is gone forever.”

  ✅ Reality: If you were over-withheld — common in the 10%–22% brackets — the excess comes back as a refund when you file.

Frequently Asked Questions

Are bonuses taxed at a higher rate than regular pay?

No. A bonus is taxed at your ordinary income tax rate, just like salary. It’s withheld differently — usually a flat 22% up front — but your final tax is identical to what you’d owe on the same amount of salary.

Why was my bonus taxed at 30%–40%?

Almost always because your employer used the aggregate method — adding the bonus to a regular paycheck and withholding on the combined total, which temporarily bumps that check into a higher withholding tier. It looks brutal but reconciles when you file.

What is the federal bonus tax rate for 2026?

The federal withholding rate is a flat 22% on bonuses up to $1 million, and 37% on any portion above $1 million. These rates are unchanged for 2026. Your actual tax is your marginal rate, settled on your return.

How much will my $10,000 bonus be taxed?

Under the flat method with no state tax, expect about $2,200 federal withheld and $765 FICA, leaving roughly $7,035. Add state tax where it applies. How much you ultimately keep depends on your bracket at filing.

Do you get bonus tax back at tax time?

Often, yes — if your marginal rate is below 22% (the 10% or 12% brackets), the flat withholding is more than you owe, so the difference comes back as a refund. If you’re in the 24%–37% range, you may owe a bit more instead.

What’s the difference between the percentage and aggregate methods?

The percentage method withholds a flat 22% on the bonus by itself. The aggregate method lumps the bonus into a regular paycheck and withholds on the total using your W-4, which can look much higher for that one check.

Are bonuses subject to Social Security and Medicare taxes?

Yes. A bonus is wages, so it’s subject to Social Security (6.2%, up to the 2026 cap of $184,500) and Medicare (1.45%, plus an extra 0.9% on wages over $200,000) — together about 7.65% in FICA.

How is a signing bonus taxed?

The same way as any other bonus: it’s a supplemental wage, withheld at the flat 22% (or via the aggregate method) and taxed as ordinary income at your marginal rate when you file.

Can I put my bonus into my 401(k) to lower taxes?

Often, yes. Many plans let you direct a bonus into a traditional 401(k), which reduces your taxable income for the year — subject to your plan’s rules and the annual contribution limits. It lowers taxable income; it doesn’t change the tax rate.

Do bonuses get taxed twice?

No. A bonus is taxed once as income, plus normal FICA — the same taxes on any wages. The “twice” feeling usually comes from seeing both big withholding and FICA on one stub.

Is it better to get a bonus or a raise?

Taxes treat them the same on your final bill. A raise wins on permanence and compounding; a bonus is one-time and not guaranteed. Choose based on long-term value and certainty, not tax strategy.
