How Are Bonuses Taxed in 2026?

Bonuses are classified as supplemental wages by the IRS, which means they follow different withholding rules than your regular paycheck. Understanding how bonus taxation works can help you plan your finances and avoid surprises at tax time. Whether you receive an annual performance bonus, a signing bonus, or a holiday bonus, the same federal rules apply.

Your employer must choose one of two IRS-approved methods to withhold federal income tax from your bonus: the percentage method or the aggregate method. The method your employer uses directly affects how much of your bonus you take home on payday — though your final tax liability remains the same when you file your return.

Percentage Method vs. Aggregate Method

The IRS gives employers two options for withholding taxes on supplemental wages. Each produces a different amount withheld from your paycheck, but neither changes the actual tax you owe at the end of the year.

The Percentage (Flat) Method

The percentage method is the most common approach. Your employer withholds a flat 22% federal income tax on the bonus, regardless of your regular income or tax bracket. This method is simple and predictable. For example, on a $10,000 bonus, exactly $2,200 is withheld for federal income tax before FICA taxes are applied.

The 22% rate applies to the first $1 million in supplemental wages received during the calendar year. Any supplemental wages above $1 million are withheld at the top marginal rate of 37%. This higher rate applies to the excess amount only — not to the entire bonus.

The Aggregate Method

With the aggregate method, your employer combines your bonus with your most recent regular paycheck and calculates withholding on the total as if it were a single payment. This often results in higher withholding because the combined amount pushes the calculation into a higher tax bracket. While this can feel like you are being "taxed more," it is purely a withholding difference — you will reconcile the amount when you file your income tax return.

Supplemental Wage Tax Rate: 22% Explained

The 22% flat withholding rate is not a special "bonus tax." It is simply the default withholding rate the IRS mandates for supplemental wages. Supplemental wages include bonuses, commissions, overtime pay (when paid separately), severance pay, back pay, retroactive pay increases, and taxable fringe benefits.

If your actual marginal tax bracket is lower than 22%, you will receive a refund for the over-withheld amount when you file. Conversely, if your bracket is higher — say 24% or 32% — you may owe additional tax. The flat rate is simply a convenient estimate that works reasonably well for most middle-income earners.

Bonuses Over $1 Million: The 37% Rate

When your cumulative supplemental wages for the calendar year exceed $1 million, the excess is withheld at the top marginal tax rate of 37%. This is a significant increase from the standard 22% rate. For example, if you receive a $1.5 million bonus, the first $1 million is taxed at 22% ($220,000), and the remaining $500,000 is taxed at 37% ($185,000), for a total federal withholding of $405,000.

Keep in mind that the $1 million threshold is cumulative. If you received $800,000 in commissions earlier in the year and then receive a $400,000 year-end bonus, the first $200,000 of that bonus is withheld at 22% and the remaining $200,000 at 37%.

FICA Taxes on Your Bonus

In addition to federal income tax withholding, your bonus is subject to FICA taxes — Social Security and Medicare. These taxes apply to bonuses the same way they apply to regular wages:

• Social Security tax: 6.2% on earnings up to $176,100 (2026 wage base). If your year-to-date earnings plus the bonus exceed this limit, only the portion below the cap is subject to Social Security tax.
• Medicare tax: 1.45% on all earnings with no wage cap. An additional 0.9% Medicare surtax applies to earnings over $200,000 for single filers ($250,000 for married filing jointly).

For someone who has already earned $170,000 in salary and receives a $20,000 bonus, only $6,100 of the bonus ($176,100 minus $170,000) is subject to Social Security tax. The full $20,000 is still subject to Medicare tax. Use our paycheck calculator to see how FICA affects your regular take-home pay.

Social Security Wage Base Impact

The Social Security wage base for 2026 is $176,100. Once your combined salary and bonus exceed this threshold, you stop paying the 6.2% Social Security tax on additional earnings. This is why higher earners sometimes see a slightly lower effective tax rate on their bonuses — the Social Security portion is capped.

If you are a dual-income household, each spouse has their own $176,100 cap. However, if one spouse earns well above the cap, the savings on Social Security tax can be substantial. Entering your year-to-date salary in the calculator above gives you a more accurate estimate of your net bonus.

Withholding vs. Actual Tax Liability

One of the most important concepts to understand is the difference between withholding and your actual tax liability. The 22% withheld from your bonus is simply an estimated prepayment. Your true tax rate depends on your total annual income, filing status, deductions, and credits.

For example, a single filer earning $40,000 in salary with a $5,000 bonus has $45,000 in total income. After the $15,000 standard deduction, their taxable income is $30,000, placing them in the 12% bracket. Since 22% was withheld on the bonus but their actual rate is 12%, they will receive a refund of the difference. Conversely, a high earner in the 35% bracket will owe additional tax beyond the 22% withheld.

When to Time Your Bonus

If you have flexibility in when you receive your bonus, timing can affect your tax situation. Deferring a bonus into the next calendar year may be beneficial if you expect to be in a lower tax bracket (for example, if you plan to take a sabbatical or reduce hours). Conversely, accelerating a bonus into the current year might make sense if you expect higher income next year.

Timing also matters for the Social Security wage base. If you have not yet reached $176,100 in earnings, receiving the bonus in December means more of it may be subject to Social Security tax than if you wait until January when the counter resets. Consider consulting a tax professional to optimize timing for your specific situation.

Worked Example: $10,000 Bonus

Let us walk through a complete example. Suppose you earn $75,000 in salary and receive a $10,000 year-end bonus. Your employer uses the percentage (flat) method:

In this example, the effective federal-plus-FICA rate is 29.65%. If you live in a state with income tax, such as California (up to 13.3%) or New York (up to 10.9%), your take-home could be significantly less. States with no income tax — like Texas, Florida, and Nevada — let you keep more of your bonus. Use our withholding calculator to factor in state taxes.

State Tax on Bonuses

Most states treat bonuses as supplemental wages and tax them at either a flat supplemental rate or your marginal state rate. States like California use a flat 10.23% supplemental rate, while New York uses a flat 11.7%. Some states, like Pennsylvania, tax all income at a flat rate regardless of type (3.07%). And nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all.

Tips to Maximize Your Bonus

• Increase 401(k) contributions: Ask your employer to direct part of your bonus into your 401(k). Pre-tax contributions reduce taxable income dollar-for-dollar, up to the $23,500 limit for 2026.
• Contribute to an HSA: If you have a high-deductible health plan, contributing bonus money to a Health Savings Account provides a triple tax benefit: tax-deductible going in, tax-free growth, and tax-free withdrawals for medical expenses.
• Adjust your W-4: If the 22% flat rate results in over-withholding, you can adjust your W-4 withholding for the rest of the year to compensate, increasing your regular paycheck amounts.
• Offset with deductions: Charitable donations, mortgage interest, and other itemized deductions can help offset the tax impact of a large bonus.
• Consider Roth conversions: In a year when your bonus pushes you into a higher bracket, the additional tax cost of a Roth conversion may be worth it for long-term tax-free growth.

Common Bonus Tax Myths

Myth: "Bonuses are taxed at a higher rate than regular income." This is the most common misconception. Bonuses are not taxed at a special higher rate. They are subject to the same federal income tax brackets as all other income. The 22% flat withholding rate may be higher or lower than your actual bracket — it is simply a withholding convenience, not a separate tax rate.

Myth: "I should ask for a raise instead of a bonus to pay less tax." From a tax perspective, a $10,000 raise and a $10,000 bonus result in the same total tax liability. The only difference is how much is withheld from each paycheck versus reconciled at filing time.

Myth: "If I defer my bonus, I avoid paying tax on it." Deferring a bonus to the next year does not eliminate the tax — it simply shifts when you pay it. However, if you expect to be in a lower bracket next year, deferral can reduce your overall rate. Check your tax bracket to compare scenarios.

How to Use Your Bonus Wisely

After taxes, your bonus represents an opportunity to make a meaningful financial move. Financial advisors often recommend the following priority order for allocating bonus income:

1. Pay off high-interest debt: Credit card debt at 20%+ APR should be the first priority. Paying down $5,000 in credit card debt saves $1,000+ per year in interest.
2. Build an emergency fund: Aim for 3 to 6 months of expenses. A bonus can jumpstart this safety net if you do not have one.
3. Maximize retirement contributions: If you have not maxed your 401(k) or IRA, a bonus is an efficient way to catch up on contributions.
4. Make extra mortgage payments: Even one extra payment per year can shave years off your mortgage. Use Amortio to calculate the interest savings from extra principal payments.
5. Invest in a taxable brokerage account: After maximizing tax-advantaged accounts, taxable investing provides long-term growth with favorable capital gains tax rates.

The key is to decide how to allocate your bonus before you receive it. Without a plan, bonus money tends to be absorbed into everyday spending without making a lasting financial impact. Consider setting up automatic transfers to your savings or investment accounts on the day you expect the bonus to hit your bank account.

Bonus Tax Planning Calendar

Smart bonus tax planning follows a calendar. In January through March, review your W-4 and adjust withholding based on expected bonuses for the year. During Q2 and Q3, track your year-to-date earnings relative to the Social Security wage base and your expected tax bracket. In Q4, if you know a year-end bonus is coming, consider maximizing 401(k) contributions or making charitable donations to offset the additional income. By December 31, ensure all tax-advantaged contributions are completed for the calendar year.

Retention Bonuses and Clawback Provisions

A retention bonus is a lump-sum payment given to employees as an incentive to remain with the company for a specified period, often during mergers, acquisitions, or organizational restructuring. These bonuses are taxed identically to other supplemental wages — at the flat 22% federal rate. However, retention bonuses frequently come with clawback provisions requiring repayment if you leave before the retention period ends.

If you repay a clawed-back bonus in the same calendar year you received it, your employer typically adjusts your W-2 and you owe no tax on the repaid amount. If the repayment occurs in a different year, you can claim a deduction or credit under IRC Section 1341 (the "Claim of Right" doctrine). The tax rules for clawbacks can be complex — consult a tax professional if you face this situation.

Bonus Taxation for Self-Employed Workers

If you are self-employed or an independent contractor, bonuses work differently. Client bonuses or performance incentives are simply additional self-employment income. They are subject to self-employment tax (15.3% for Social Security and Medicare combined) in addition to federal income tax. There is no employer to withhold the flat 22% — you are responsible for estimated quarterly tax payments.

Freelancers can offset bonus income with business deductions such as home office expenses, equipment, software, and professional development. If your bonus pushes your quarterly income significantly higher, consider making an additional estimated tax payment to avoid underpayment penalties.

International Bonus Taxation

If you work abroad or receive bonuses from foreign employers, additional tax considerations apply. US citizens and resident aliens are taxed on worldwide income, including foreign bonuses. You may be able to claim the Foreign Earned Income Exclusion (up to $130,000 for 2025) or the Foreign Tax Credit to avoid double taxation. Expatriate bonuses paid in foreign currency must be converted to US dollars at the exchange rate on the date received.

Non-resident aliens working in the US are generally subject to the same supplemental wage withholding rules on US-source bonuses. However, tax treaty provisions between the US and your home country may reduce or eliminate withholding. Check IRS Publication 519 (US Tax Guide for Aliens) for details specific to your situation.

Deferred Compensation Plans and Bonuses

Some employers offer nonqualified deferred compensation (NQDC) plans that allow you to defer a portion of your bonus to a future year, postponing the income tax (though not the timing of Social Security and Medicare taxes, which apply at vesting). NQDC plans are commonly available to executives and highly compensated employees. The deferral election must typically be made before the start of the year in which the bonus is earned — you cannot defer after the fact.

While deferral can be advantageous if you expect to be in a lower tax bracket in retirement, it carries risk. Unlike 401(k) funds, deferred compensation is an unsecured promise from your employer. If the company goes bankrupt, you may lose the deferred amount. Weigh the tax benefit against the credit risk before electing deferral.

Net Bonus by Income Level

Your actual take-home amount from a bonus depends on your income level because higher earners may have already exceeded the Social Security wage base. Here is a comparison of net bonus amounts for a $10,000 bonus at different salary levels:

Notice that earners above the $176,100 Social Security wage base pay no SS tax on the bonus, resulting in a higher net amount. However, earners above $200,000 face the 0.9% Additional Medicare Tax, which partially offsets the SS savings. These are withholding amounts only — your actual tax may differ at filing time based on your total annual effective tax rate.
