Summary

You'd take home about $7,035 of a $10,000 bonus

Federal supplemental withholding is a flat 22% ($2,200), plus $765 of Social Security and Medicare. That leaves $7,035 in your account.

Recommendation~$200 due at filing

That 22% isn't a special bonus tax rate — it's just withholding

The single most common misconception about bonuses is that they're taxed at a higher rate. They aren't. The flat 22% is a withholding shortcut for supplemental wages; your bonus is ultimately taxed as ordinary income at your marginal rate like any other pay. At your 24% rate, the true liability is $2,400, so you'd owe about $200 more at filing.

Opportunity

Deferring part of it to a 401(k) cuts the tax

If your employer allows a separate bonus deferral, routing even 25% ($2,500) into your 401(k) would save about $600 in federal tax and send the money to retirement instead. Bonuses are ideal for this because you haven't built the money into your budget — it's the least painful way to save.

Next step

Check your overall withholding

A large bonus can shift your total withholding for the year in either direction. See whether you're on track for a refund or a bill.

At your 32% rate, the true liability is $3,200, so you'd owe about $1,000 more at filing.

Opportunity

Deferring 50% saved $3,200 in tax

Routing $10,000 of the bonus into your 401(k) keeps it out of taxable income entirely, saving roughly $3,200 at your marginal rate — and it goes straight to retirement instead of being spent. Note FICA still applies to the full bonus. Many employers let you set a separate deferral rate for bonuses.

The basics

How bonuses are actually taxed

A bonus is ordinary income, taxed at the same rates as your salary. What's different is the withholding. The IRS classifies bonuses as 'supplemental wages', and the most common approach — the percentage method — withholds a flat 22% federally (37% on amounts above $1 million), regardless of your actual bracket.

That flat rate is why bonuses feel taxed more heavily. If your marginal rate is 12% or 22%, the withholding is close to right or even generous. If your marginal rate is 32% or 35%, the flat 22% under-withholds and you'll owe the difference at filing. Either way, the eventual tax is your ordinary rate — the withholding is just an estimate that settles up on your return.

  • Flat 22% federal withholding on supplemental wages
  • 37% on amounts above $1 million
  • Social Security and Medicare (7.65%) also apply
  • Final tax is your ordinary marginal rate, settled at filing

Making the most of a bonus

Bonuses are the ideal money to save, precisely because you haven't built them into your monthly budget. Many employers allow a separate 401(k) deferral election for bonuses — routing part or all of it into retirement keeps it out of taxable income entirely, saving your full marginal rate while sending the money somewhere useful. Note that Social Security and Medicare still apply even to deferred amounts.

The aggregate method is the other withholding approach some employers use, combining the bonus with regular pay and withholding as if that were your normal paycheck. It often withholds more than the flat rate for a large bonus, which can feel worse but is frequently closer to the correct amount for high earners. Either way, the difference resolves on your tax return — a large withholding on a bonus is not money lost.

Common mistakes

  1. 1

    Believing bonuses are taxed at a higher rate

    The flat 22% is withholding, not a tax rate. Bonuses are ordinary income and settle at your normal rate on your return.

  2. 2

    Spending the gross amount

    Withholding takes roughly 30% before it reaches you. Budget from the net figure, not the announced bonus.

  3. 3

    Missing the 401(k) deferral option

    Many employers allow a separate bonus deferral. It's the least painful way to save and cuts tax at your full marginal rate.

  4. 4

    Being surprised by a bill at filing

    High earners are under-withheld by the flat 22%. If your rate is 32%+, set some aside for the difference.

  5. 5

    Forgetting FICA applies to deferrals

    Deferring to a 401(k) avoids income tax but not Social Security and Medicare, which apply to the full bonus.

Common questions

How is a bonus taxed?

A bonus is ordinary income taxed at your normal marginal rate. What differs is withholding: employers typically withhold a flat 22% federally under the supplemental wage rules (37% above $1 million), plus 7.65% for Social Security and Medicare. Any difference between that withholding and your real liability settles on your tax return.

Why was my bonus taxed at 22%?

That's not a special bonus tax rate — it's the flat federal withholding rate for supplemental wages, a shortcut employers use instead of calculating your exact bracket. Your bonus is ultimately taxed as ordinary income. If your marginal rate is below 22% you'll get some back; if it's above, you'll owe the difference at filing.

How much of a $10,000 bonus do I take home?

Roughly $7,000–7,200 federally: about $2,200 in flat federal withholding plus $765 in Social Security and Medicare. State income tax, where it applies, reduces it further. Deferring part of the bonus to a 401(k) increases what you keep by removing it from taxable income.

Can I avoid tax on my bonus?

You can't avoid it, but you can defer it. Contributing part or all of a bonus to a traditional 401(k) or HSA removes it from taxable income for the year, saving your full marginal rate. Social Security and Medicare still apply. Many employers allow a separate deferral election specifically for bonuses.

Will I get some bonus tax back?

If your marginal rate is below the flat 22% withholding, yes — the excess comes back as part of your refund. If your rate is higher, you'll owe the difference instead. The flat withholding is only an estimate; your actual liability is calculated on your return using your ordinary rates.
