A bonus can make your paycheck look as though it was taxed at a much higher rate than your regular salary. For U.S. employees, this often happens because employers use special federal income tax withholding methods for bonuses. In 2026, the commonly used flat withholding rate is 22%, but that is not necessarily your final tax rate. Your actual income tax is determined using your total taxable income and other circumstances for the year.
If your bonus deposit was smaller than expected, the first step is to separate federal income tax withholding from Social Security, Medicare, state taxes, and other payroll deductions. That distinction helps you decide whether anything needs to be corrected.
Why Is Tax Withholding Higher After a Bonus?
Most employee bonuses count as supplemental wages. These are payments made in addition to regular compensation, including certain commissions, awards, and other forms of additional pay.
Under the IRS supplemental wage withholding rules in Publication 15, employers can use different methods to calculate federal income tax withholding on these payments.
Two common methods explain why your bonus may look different from your usual paycheck:
- Percentage method: The employer withholds federal income tax at a flat 22% rate on separately identified supplemental wages when the method is permitted.
- Aggregate method: The employer combines the bonus with regular wages for withholding calculations, then subtracts withholding attributable to regular wages.
The second method can produce an unexpectedly large deduction because payroll withholding calculations may temporarily treat the combined amount as representative of a regular pay period.
Neither method automatically means your bonus is subject to a special final income tax rate.
Bonus Withholding Rates for 2026
For federal income tax withholding during calendar year 2026, the standard supplemental wage rules are:
| Situation | Federal withholding treatment |
|---|---|
| Separately identified bonus, eligible for flat-rate method | 22% federal income tax withholding |
| Bonus paid using aggregate method | Calculated using applicable regular payroll withholding tables |
| Supplemental wages exceeding $1 million during the calendar year | 37% mandatory federal withholding on the excess |
The $1 million threshold applies to cumulative supplemental wages, not simply to your total annual salary. Special aggregation rules can apply to related employers.
The optional 22% method generally requires that the employer withheld federal income tax from your regular wages during the current or preceding calendar year. If that condition is not met, the aggregate calculation generally applies.
These percentages describe federal income tax withholding only. State income tax withholding and payroll taxes may be added separately.
Why 22% Withholding Is Not the Same as a 22% Tax Rate
It is important to distinguish between tax withholding and final income tax liability.
Withholding is money your employer sends to the government in advance on your behalf. Your actual federal income tax is calculated when you prepare your annual income tax return.
That calculation considers relevant factors including:
- Total taxable earnings from salary, bonuses, and other income.
- Your tax filing status.
- Applicable deductions and credits.
- Other household income, including a spouse's earnings when relevant.
- Additional tax payments and withholding throughout the year.
For example, a person whose additional income falls in a 12% marginal federal tax bracket might have 22% withheld from an eligible separately paid bonus. Another person whose additional income falls in a 32% bracket could have the same 22% withheld.
In the first situation, the bonus withholding may be higher than the additional federal income tax attributable to the bonus. In the second situation, it may be lower.
These comparisons are simplified because deductions, credits, changes in tax brackets, and other income can affect the actual result.
The essential point: A bonus does not have its own permanent federal income tax bracket simply because it is a bonus. It generally becomes part of your taxable compensation.
Example: How Much of a $5,000 Bonus Might You Receive?
Consider an illustrative 2026 payroll scenario with the following assumptions:
- Gross cash bonus: $5,000.
- Employer uses the permitted 22% federal supplemental wage withholding method.
- The entire bonus is subject to Social Security and Medicare taxes.
- The employee has not reached the annual Social Security wage limit.
- No Additional Medicare Tax applies.
- No state or local income tax, retirement contribution, or other payroll deduction is included.
| Calculation | Amount |
|---|---|
| Gross bonus | $5,000.00 |
| Federal income tax withholding (22%) | -$1,100.00 |
| Social Security tax (6.2%) | -$310.00 |
| Medicare tax (1.45%) | -$72.50 |
| Estimated bonus take-home pay | $3,517.50 |
In this example, total federal withholding and employee payroll taxes equal $1,482.50, or 29.65% of the gross bonus.
That is why someone might describe a bonus as being "taxed at almost 30%" even though the federal income tax withholding component is only 22%.
The difference is mainly the additional 7.65% withheld for Social Security and Medicare.
The actual net payment could be lower if state income taxes, local taxes, retirement plan contributions, or other deductions apply. It could also differ if the Social Security wage limit has already been reached.
What Happens When Your Employer Uses the Aggregate Method?
The aggregate method is another major reason that bonus withholding can look unusually high.
Rather than using a flat 22% withholding rate, the employer determines withholding using the bonus combined with regular wages according to the applicable payroll withholding rules.
An Illustrative Biweekly Paycheck
Suppose an employee normally receives $3,000 in gross wages every two weeks and receives an additional $5,000 bonus.
Payroll may calculate federal income tax withholding using an $8,000 combined wage amount for the relevant biweekly payroll period.
Under one aggregate-method calculation:
- The regular gross wages are $3,000.
- The bonus adds $5,000.
- The combined amount is $8,000.
- Payroll calculates federal withholding on the combined payment using the applicable withholding method and Form W-4 information.
- The withholding attributable to regular wages is subtracted to determine the federal withholding assigned to the bonus.
Because the payroll tables account for pay frequency, an $8,000 biweekly payment can produce a higher withholding amount than the employee expected from their normal $3,000 paycheck.
This does not mean the employee is necessarily expected to earn $8,000 every two weeks for the entire year. It reflects the withholding calculation for that payroll period.
The precise amount depends on the applicable withholding tables, filing status, Form W-4 elections, payroll timing, and any other supplemental payments included in the calculation. A particular aggregate-method percentage cannot be assumed without those details.
The IRS Publication 15-T withholding tables explain how regular payroll withholding is calculated.
Other Taxes That Can Reduce Your Bonus
Federal income tax withholding is only one part of a paycheck deduction. For most employees, the bonus is also subject to employment taxes.
Social Security Tax
For 2026, the employee Social Security tax rate is 6.2%, with a wage base limit of $184,500.
Once an employee reaches that wage limit with the same employer, additional covered wages generally are not subject to further Social Security tax withholding by that employer for the year.
Employees with multiple employers may have excess Social Security tax withheld, which can be addressed under applicable federal income tax return rules.
Medicare Tax
The regular employee Medicare tax rate is 1.45%. Unlike Social Security, Medicare does not have an annual wage base limit.
Employers must also withhold an additional 0.9% Medicare tax on wages they pay an employee above $200,000 during the calendar year, regardless of that employee's filing status.
The actual Additional Medicare Tax liability on an individual income tax return can depend on filing status and combined wages.
These rules are explained in the IRS guide to Social Security and Medicare withholding.
State and Local Income Taxes
Depending on where you work and live, your bonus may also be subject to state or local income tax withholding.
Some jurisdictions have specific supplemental wage withholding procedures, while others generally rely on methods related to regular wage withholding.
State tax withholding should be checked against the rules of the actual state involved. A federal 22% calculation does not determine the amount of state tax withheld.
Retirement Contributions and Other Deductions
Your net bonus can also depend on whether your employer applies retirement plan contributions or other benefits-related deductions.
For example, an eligible traditional 401(k) contribution may reduce wages subject to federal income tax withholding but generally does not eliminate Social Security or Medicare taxes. Roth 401(k) contributions generally do not reduce current federal taxable wages.
Check your employer's plan rules before assuming that your usual contribution percentage will automatically apply to a bonus.
How to Check Whether Your Bonus Withholding Looks Correct
Before requesting a payroll correction, compare your bonus pay statement with your ordinary paycheck.
The most useful review is not a comparison of net pay percentages alone. Instead, examine each deduction separately.
Bonus Paycheck Review Checklist
- Identify the gross bonus. Confirm the amount before taxes and deductions.
- Locate federal income tax withholding. This may appear as FIT, FITW, federal withholding, or a similar label.
- Separate Social Security and Medicare. Do not include these amounts when calculating the federal income tax withholding percentage.
- Check state and local deductions. Their treatment may differ from federal withholding.
- Identify retirement and benefit deductions. Determine whether they are applicable to the bonus payment.
- Ask payroll which withholding method was used. A separate bonus payment does not by itself establish that the 22% method was used.
- Compare year-to-date withholding. One paycheck may not accurately reflect whether your total annual withholding is sufficient.
A simple first calculation is:
Federal bonus withholding percentage = Federal income tax withheld from the bonus ÷ Gross bonus subject to that withholding × 100
For example, if federal income tax withholding attributable to a $5,000 bonus is $1,100:
$1,100 ÷ $5,000 × 100 = 22%.
If the paycheck combines regular pay and bonus pay, the federal withholding reported for the entire paycheck should not automatically be divided by the bonus amount. You first need to identify the portion attributable to the bonus.
When Should You Adjust Your Form W-4 After a Bonus?
A larger-than-usual withholding deduction is not automatically a reason to change your Form W-4.
The more important question is whether your total federal income tax withholding for the year is likely to match your anticipated federal tax liability reasonably well.
Reviewing your W-4 can be useful when:
- You receive an unexpectedly large bonus.
- You receive bonuses or commissions several times a year.
- You have more than one job.
- Your spouse also earns income.
- You expect substantial income not subject to payroll withholding.
- You recently changed filing status or experienced another significant tax-related life event.
- Your year-to-date withholding appears substantially different from your expected tax liability.
The IRS Tax Withholding Estimator can help eligible employees review their federal withholding using current pay statements and expected income.
When using the estimator, distinguish bonuses already received from bonuses expected later in the year. Past payments are reflected in year-to-date figures, and including them again as future bonuses can distort the result.
If an adjustment is appropriate, you can submit an updated Form W-4 to your employer.
Changing Form W-4 generally affects the withholding calculation for regular wages and applicable aggregate-method payments. It does not necessarily override the optional flat supplemental wage withholding method.
You should not reduce withholding solely because one bonus paycheck appears heavily taxed. Doing so could create an underpayment later in the year.
Decision Guide: Should You Take Action?
Use the following guide after reviewing your pay statement.
| What you notice | Practical next step |
|---|---|
| Federal withholding is exactly 22% of the separately identified bonus | Check whether your annual total withholding is sufficient. The percentage alone does not indicate an error. |
| Federal withholding is substantially above 22% | Ask whether the aggregate method or another applicable rule was used. |
| Total deductions approach 30% or more | Separate federal income tax, payroll taxes, state taxes, and benefit deductions. |
| The bonus caused a major increase in annual income | Review projected annual income tax and withholding, not just the bonus paycheck. |
| Pay statement appears inconsistent with your gross bonus or payroll elections | Request an itemized explanation from payroll or human resources. |
This approach helps distinguish a normal withholding result from a possible payroll error.
Could You Receive the Extra Withholding Back as a Tax Refund?
Possibly, but a refund is not automatic simply because your employer withheld 22% or more from a bonus.
Your federal income tax return reconciles total tax liability with the federal income tax already paid through withholding and other payments.
If total eligible payments and refundable credits exceed your final tax liability, you may receive a refund, subject to other applicable adjustments.
If those payments are insufficient, you may owe additional tax.
Consider two simplified illustrative situations:
Scenario A: More Tax Was Withheld Than Ultimately Needed
Suppose an employee has an additional $5,000 of taxable bonus income, and the incremental federal income tax associated with that income is $600.
If $1,100 was withheld for federal income tax, the difference is $500.
That $500 may contribute to a larger refund or reduce a balance due, depending on all other items on the employee's return.
This example assumes an incremental 12% federal income tax burden on the entire bonus and does not model other deductions or credits.
Scenario B: Less Tax Was Withheld Than Ultimately Needed
Suppose the same $5,000 taxable bonus increases federal income tax liability by $1,600, reflecting an illustrative 32% incremental rate.
If the employer withheld only $1,100, the difference is $500.
Unless other withholding, payments, or credits cover that difference, it can increase the amount due with the annual return.
These scenarios demonstrate why the withholding percentage alone cannot tell you whether a refund is likely.
Can You Ask Your Employer to Withhold Less Tax From a Bonus?
You can ask your payroll department how bonuses are processed and whether the employer offers any permitted payroll elections.
However, the employer must follow the applicable federal and state withholding requirements.
Under the permitted flat federal supplemental wage method, the rate is 22%, not an adjustable percentage selected by the employee.
When the aggregate method applies, Form W-4 information can influence the withholding calculation.
If you believe annual federal withholding is excessive, the appropriate approach is generally to review your year-to-date tax information and determine whether a new W-4 is justified.
An employer cannot simply disregard required withholding because an employee prefers a larger net bonus payment.
Common Mistakes When Evaluating Bonus Taxes
Confusing Withholding With Final Tax
The federal withholding rate applied to a bonus does not necessarily equal the ultimate income tax associated with that payment.
Comparing the Entire Bonus Deduction With 22%
Social Security, Medicare, state taxes, and retirement deductions can make total deductions substantially greater than 22%.
Assuming a Separate Deposit Always Means Flat-Rate Withholding
A separately paid or identified bonus may still be processed using the aggregate method when applicable.
Making a W-4 Change Without an Annual Projection
Reducing withholding after one large bonus can leave a shortfall if the rest of your income is higher than expected.
Ignoring Year-to-Date Payroll Amounts
Social Security wage limits and Additional Medicare Tax withholding can affect the deductions on later bonus payments.
Frequently Asked Questions
Are bonuses taxed more heavily than regular salary?
Bonuses generally count as taxable wage income, but they can be withheld differently from regular wages. Your final income tax depends on your annual taxable income and applicable tax rules, not merely on the payroll label assigned to the payment.
Why was more than 22% deducted from my bonus?
The 22% figure is a federal income tax withholding method, not a limit on all paycheck deductions. Social Security, Medicare, state taxes, and other deductions may increase the total amount withheld. The federal income tax component itself may also differ when payroll uses the aggregate method.
Does a bonus push all my salary into a higher tax bracket?
No. Under the federal progressive income tax system, moving into a higher marginal bracket does not cause all your income to be taxed at that higher rate. Only income within the applicable portion of each bracket is taxed at that bracket's rate, subject to the overall tax calculation.
Will bonus withholding automatically be refunded?
No. A refund depends on your total tax liability compared with withholding, estimated payments, and applicable refundable credits. A flat 22% withholding rate does not establish that you overpaid.
Should I change my W-4 immediately after receiving a bonus?
Not necessarily. Review your expected annual income and federal withholding first. If the results indicate a material overpayment or shortfall, consider an appropriate W-4 adjustment.
What to Do After Receiving a Bonus
Start by comparing your regular pay statement with the bonus statement. Identify the gross bonus, federal income tax withholding, Social Security, Medicare, and any state or benefit deductions.
If the federal withholding amount is unexpected, ask payroll whether the percentage or aggregate method was used. Then review your projected annual tax position with the IRS Tax Withholding Estimator or an appropriately qualified tax professional.
Bottom line: A bonus paycheck can show a much higher withholding percentage without your bonus being permanently taxed at that percentage. Understanding the payroll method and checking your full-year tax position is more useful than judging your tax bill from a single deposit.
