How Bonuses Are Taxed

A bonus feels like confettiright up until you open your pay stub and realize the confetti came pre-seasoned with taxes. If you’ve ever wondered why your $5,000 bonus didn’t turn into $5,000 in your bank account, you’re not alone. The good news: your bonus usually isn’t “taxed differently” than your salary. The confusing part is that it can be withheld differently, and withholding is what you see immediately.

Let’s break it down in plain English (with only a little payroll-nerd energy): what the IRS considers a bonus, how employers calculate withholding, which payroll taxes still apply, how state rules can change your take-home pay, and what you can do so “bonus season” doesn’t become “surprise tax season.”

First: What counts as a “bonus” (and why the IRS calls it “supplemental wages”)

In tax-land, “bonus” often lives inside a bigger bucket called supplemental wages. Supplemental wages are wage payments that aren’t your regular hourly or salaried paycheck. That includes things like bonuses, commissions, overtime, awards and prizes, severance, back pay, certain tip income, and some taxable fringe benefits.

Translation: whether your employer calls it a “performance bonus,” “holiday bonus,” “spot bonus,” or “we-survived-Q4 bonus,” it’s still generally treated as wages for tax purposes. It ends up on your W-2 and gets taxed under the same federal income tax brackets as your other wages when you file your return.

The biggest myth: “My bonus got taxed at a higher rate!”

What most people mean is: my bonus had more money withheld than a normal paycheck. Withholding is the amount your employer sends to the IRS (and state/local agencies) in advance to cover your expected tax bill. Your actual tax is what you calculate on your tax return, based on your total income, deductions, credits, and filing status.

So if your bonus looks like it got hit with a big tax hammer, that’s often a withholding rulenot a special “bonus tax.” Depending on your overall situation, you might:

• Get some of that back as a refund (if too much was withheld), or
• Owe more at tax time (if not enough was withheld).

Think of withholding like putting money in an envelope labeled “Taxes: Do Not Touch.” Your pay stub shows the envelope being filled. Your tax return decides whether the envelope was overfilled, underfilled, or just right.

How federal income tax withholding works on bonuses

Employers typically use one of two IRS-approved approaches for withholding federal income tax on supplemental wages like bonuses. Which one they use can seriously change what you take home todayeven if your final tax bill later ends up the same.

1) The percentage method (the famous flat-rate withholding)

If your employer pays your bonus as a separate check (or clearly identifies it separately), they may withhold federal income tax using the percentage method. Under this method, a flat rate is applied to the bonus amount: 22% for supplemental wages up to $1 million (and 37% on the portion above $1 million, for very high earners).

Example: You get a $6,000 bonus paid separately.

• Federal income tax withholding (percentage method): $6,000 × 22% = $1,320
• That’s just federal income tax withholdingpayroll taxes may still apply (we’ll get there next).

This method is popular because it’s simple. Payroll loves simple. Your spreadsheet-loving coworker also loves simple. Your bank account might not love it as much if you’re in a lower tax bracketbut again, that can get reconciled at tax time.

2) The aggregate method (aka “Why is my withholding enormous?”)

The aggregate method is when your employer adds your bonus to your regular wages for the pay period and withholds as if it’s one big paycheck. This can create sticker shock because withholding tables may treat that big paycheck like you earn that amount every pay period for the whole year (even though you don’t).

Example: You normally earn $2,000 weekly. This week you get a $5,000 bonus with your paycheck.

• Payroll may treat it as $7,000 for the week.
• Withholding tables might “annualize” that amount (as if $7,000 happens every week).
• Result: the federal withholding can look dramatically higher than 22%even though it’s just an estimation method.

This is why two coworkers can get the same bonus and see different take-home pay: payroll timing and method matter.

What if the bonus isn’t separated on the check?

If your bonus is combined with regular wages and not separately identified, your employer generally withholds as if the total is a single regular wage payment for that pay period. That’s one reason some companies prefer to run bonuses on separate checks: fewer payroll headaches, fewer employee questions, and fewer “Is payroll mad at me?” emails.

Payroll taxes still apply: Social Security and Medicare

Federal income tax withholding is only part of the story. Bonuses are still generally subject to FICA payroll taxes:

• Social Security tax: typically 6.2% withheld from employee wages up to an annual wage base limit.
• Medicare tax: typically 1.45% withheld from all wages (no annual cap).
• Additional Medicare tax: an extra 0.9% withheld once your wages from that employer exceed $200,000 in a calendar year (employer withholds based on that $200,000 trigger, regardless of your filing status).

A detail that surprises people every year: Social Security tax stops once you hit the wage base limit, but Medicare keeps going. So late in the year, some high earners see Social Security withholding drop to $0, and it feels like a tiny pay raise. It’s not magicjust math.

Quick example (simplified): $5,000 bonus, paid when you’re still under the Social Security wage base.

• Social Security: $5,000 × 6.2% = $310
• Medicare: $5,000 × 1.45% = $72.50
• Federal income tax withholding (if 22% flat): $1,100
• Total withheld (just these three): $310 + $72.50 + $1,100 = $1,482.50
• Estimated take-home from the $5,000 bonus: $3,517.50 (before any state/local taxes or other deductions)

If you’ve already exceeded the Social Security wage base for the year, that 6.2% piece may be $0so the bonus “shrinks” a little less. (Your bonus is still a bonus. It just becomes a slightly less dramatic magic trick.)

State and local taxes: the “it depends” that actually matters

State rules vary widely, and some states have special supplemental wage withholding rates that apply to bonuses. A few key realities:

• Some states have no state income tax on wages, so your bonus won’t face state income tax withholding there (though other state taxes may exist).
• Some states use a flat supplemental rate for bonuses.
• Some states tax bonuses like regular wages using the same withholding tables.
• Some localities (certain cities/counties) may also have local income taxes withheld.

Two real examples (to show how different it can look):

• California: California has a flat withholding rate for bonuses/stock options (often cited as 10.23% for certain supplemental wages), plus California SDI withholding rules that apply to wages.
• New York State: New York provides a state supplemental withholding rate (published for 2026 as 11.70%), with additional guidance for how employers can calculate withholding on supplemental wages.

Bottom line: your bonus might face federal income tax withholding, FICA payroll taxes, state withholding, and possibly local withholding all before it ever reaches your checking account.

So… what’s your bonus actually taxed at on your tax return?

On your tax return, a bonus is generally treated like the rest of your wage income: it’s included in your total taxable income (after pre-tax deductions), and taxed under the normal progressive tax brackets.

That means a bonus can push some of your income into a higher marginal bracket, but it does not suddenly re-tax your entire income at the higher rate. Only the portion that falls into the higher bracket gets taxed at that higher percentage.

Example (conceptual):

• You earn $80,000 in wages.
• You receive a $10,000 bonus.
• Your taxable income increases, which may cause part of that $10,000 to be taxed at a higher marginal rate than some of your base salary.

If your employer withheld 22% on the bonus but your marginal rate on that slice of income is only 12% (after deductions/credits), you may get money back. If your marginal rate is 32%, 35%, or 37%, you may owe more at filing time.

How to avoid “bonus season” turning into a tax surprise

You can’t (legally) make taxes disappear, but you can make them less shocking and more predictable. Here are practical moves that help in real life.

1) Look at your pay stub like a detective, not a victim

Check whether the bonus was paid separately or combined with regular wages. That often explains the withholding method right away. Also check your year-to-date wages: if you’re near the Social Security wage base, the FICA withholding pattern can change.

2) If you’re consistently owing at tax time, adjust your W-4

If bonuses, commissions, or a second job are causing underwithholding, you can submit a new W-4 to increase withholding. This doesn’t change your tax rateit just helps you prepay closer to what you’ll owe.

3) If you’re consistently getting huge refunds, you may be overwithheld

A big refund can feel nice, but it’s also a sign you gave the government an interest-free loan. Some people prefer that forced savings; others would rather keep more in each paycheck. Either choice is finejust choose on purpose.

4) Consider retirement contributions (if your plan allows bonus deferrals)

Some workplace retirement plans let you contribute a portion of your bonus to a 401(k) as pre-tax or Roth contributions. Pre-tax contributions may reduce your federal (and often state) taxable wages, which can reduce income tax owed. Whether you can do thisand how quickly you must elect itdepends on your employer’s plan rules, so check ahead of time.

5) Remember the “two-paycheck” trap (especially with multiple jobs)

Withholding tables are usually built around the idea that each employer is your only employer. If you have two jobs, a spouse’s income, or side income, withholding can drift away from what you truly owe. That doesn’t mean anyone did anything wrongit just means your situation is more complicated than the default assumptions.

FAQ: quick answers people actually want

Are bonuses taxed at 22%?

Not exactly. They may be withheld at 22% for federal income tax under the percentage method. Your actual tax rate on that income depends on your full-year tax situation.

Why does my bonus withholding look higher than my normal paycheck?

Often because the bonus was combined with regular pay and withheld using the aggregate method, which can “annualize” the paycheck for withholding calculations. It’s an estimate, not a lifetime sentence.

Do bonuses get hit with Social Security and Medicare taxes?

Generally yes. Social Security applies up to the annual wage base, Medicare applies to all wages, and Additional Medicare withholding can kick in after $200,000 in wages from that employer in a year.

If too much is withheld, will I get it back?

If your total withholding exceeds your final tax liability, you typically get the difference back as a refund when you file your return. (Or you can adjust withholding to keep more during the year.)

What about bonuses paid in stock or RSUs?

Many stock-based awards are taxed as compensation when they vest or when you exercise (depending on the type). Employers often withhold by selling shares or withholding shares to cover taxes. The details depend on the plan and award type, so it’s worth reading your plan documents and pay statements closely.

Bonus-season experiences (real-world scenarios that feel painfully familiar)

To make this less abstract, here are common “bonus season” experiences people run intoplus what they learn from them. If any of these sound like you, congratulations: you are normal, not cursed.

Experience #1: “My $10,000 bonus turned into… $6,400?”

Someone gets a nice round bonussay $10,000and expects maybe a little tax, but not a full-on disappearing act. The pay stub shows federal withholding, Social Security, Medicare, state withholding, and maybe a local tax. Suddenly the take-home number looks like it got tackled by five linebackers.

The lesson: the “bonus haircut” isn’t one taxit’s a stack of withholdings. Federal withholding might be 22% under the flat method, Social Security could be 6.2% (if the person hasn’t hit the wage base), Medicare is 1.45%, and the state may take its own bite. Once you realize it’s multiple layers, it stops feeling like your employer made up a random “bonus tax.”

Experience #2: “My bonus was included in my paycheck and withholding went nuclear.”

Another person gets the same bonus amount, but it’s combined with a regular paycheck and withheld using the aggregate method. Their federal income tax withholding is way more than 22% of the bonusso they assume they’ve been shoved into a scary bracket. The mood: panic.

The lesson: withholding tables can treat that pay period like it represents your usual pay, effectively annualizing it. That doesn’t mean your entire year is taxed at that implied rate. It means the withholding estimate is conservative because payroll would rather over-collect than under-collect. Many people in this scenario get some of it back at filing time.

Experience #3: “I changed jobs mid-year and now I owe.”

A person switches employers in June, gets a sign-on bonus or a performance bonus at the new job, and assumes their withholding is fine because “payroll handled it.” Then tax time arrives, and they owe more than expected.

The lesson: each employer withholds based only on what they pay you, not your full-year picture. If you had higher total income than either employer “saw” aloneor you had gaps, bonuses, or extra incomeyour withholding may not line up with your final tax bill. This is where updating your W-4 or making estimated payments can save you from the April surprise.

Experience #4: “Why did Social Security stop coming out of my checks?”

High earners sometimes notice that late in the year their paychecks jump slightly because Social Security withholding drops to zero. Then they get a bonus and the Social Security still doesn’t come out, so they assume something is broken (or secretly awesome).

The lesson: Social Security tax has an annual wage base cap. Once you hit it, you stop paying that 6.2% for the remainder of the year. Medicare continues, and Additional Medicare can kick in at higher wage levels. Understanding the cap helps you predict your net pay changes and reduces the “pay stub mystery” factor.

Experience #5: “I moved states and my bonus got complicated.”

Someone relocates from a no-income-tax state to a state with income tax (or vice versa), then gets a bonus around the transition. They see unexpected state withholding or get a tax form that allocates wages across states. Confusion follows.

The lesson: state withholding and tax filing rules depend on residency and where the work was performed. A bonus paid after a move may be taxed differently than one earned before a move, and allocation rules can apply. If you have a multi-state year, it’s often worth getting professional helpor at least setting aside time to file carefully.

Conclusion

Bonuses aren’t a separate magical category of income with a secret “bonus tax.” They’re usually wages, taxed under the same federal system as your regular pay. The reason bonuses feel heavily taxed is that withholding rules can be blunt instruments: a flat 22% method for many bonuses, an “annualized” aggregate method for others, plus payroll taxes and state/local withholding on top.

The best way to stay sane is to separate withholding from what you actually owe, check how your bonus was paid, and adjust your W-4 or planning if you routinely owe (or routinely get huge refunds). Bonus season should feel like a rewardnot a pop quiz you didn’t study for.
