2026 Bonus Tax Facts
The IRS classifies bonuses as supplemental wages. The flat federal withholding rate is 22% for amounts up to $1 million, and 37% on any amount above $1 million in a calendar year.
Social Security (6.2%) and Medicare (1.45%) taxes apply to bonuses. The 2026 Social Security wage base is $184,500. Medicare has no earnings cap.
Nine states have no income tax. Others apply a separate supplemental rate ranging from 3.9% to 10.23%. California has the highest flat bonus rate at 10.23%.
Employers can use the flat rate method (22% straight) or the aggregate method (bonus added to regular pay to determine the withholding rate). Both are legal under IRS rules.

Bonus Breakdown at a Glance
Flat Rate vs. Aggregate Method
How This Calculator Works
Input your gross bonus before any taxes or deductions. This is the amount your employer promised, not what you expect to take home.
The flat rate method applies a straight 22% federal withholding. The aggregate method adds your bonus to your regular paycheck and calculates withholding on the combined total, then subtracts what was already withheld. Use aggregate if your bonus is on the same check as your regular pay.
State supplemental tax rates are applied automatically. For example, California applies 10.23% to bonuses. Texas and Florida apply 0% because they have no state income tax.
Social Security (6.2%) is applied to your bonus up to the 2026 wage base of $184,500. Medicare (1.45%) applies to all bonus income. If your total income exceeds $200,000 (single filers), an additional 0.9% Medicare surtax applies.
If you enter 401(k) or HSA contributions allocated to this bonus, they reduce your taxable income for federal and state income tax before withholding is calculated. FICA taxes are not reduced.
Your take-home bonus equals your gross bonus minus all applicable withholdings and pre-tax deductions. The result shows exactly what should land in your bank account.
Key Information About Bonus Taxes in 2026
Bonuses Are Supplemental Wages
The IRS defines bonuses as supplemental wages, which are payments made in addition to an employee's regular wages. This category also includes commissions, overtime pay, prizes, and severance pay. Because they are supplemental, a separate withholding method applies. You can learn more about how supplemental wages are calculated on our dedicated tool.
The Flat Rate vs. Aggregate Method
Most employers use the flat 22% method when paying bonuses on a separate check. The aggregate method is used when the bonus is included on the same paycheck as regular wages. Under the aggregate method, the combined amount is annualized, tax is calculated on the full annualized amount, and the withholding is prorated back to the pay period. This can result in a higher or lower withholding rate than 22%, depending on your annual income. Compare this to a standard paycheck calculation to understand your full picture.
Bonuses Over $1 Million
If your cumulative supplemental wages for the 2026 calendar year exceed $1 million, the IRS requires mandatory 37% withholding on the portion above $1 million. The first $1 million is still withheld at 22%. This rule applies regardless of the method your employer uses. For high earners, it is worth consulting with a tax professional to plan around this threshold.
Withholding Is Not Your Final Tax
The 22% flat rate is a withholding rate, not your actual tax rate. Your final tax liability on the bonus is determined when you file your return and depends on your total income, filing status, deductions, and credits. If your real marginal rate is 12%, you may get money back. If it is 32%, you may owe more. Use our federal tax calculator to estimate your full-year liability. You can also explore tax withholding adjustments to optimize your W-4.
Maximizing Your Bonus Take-Home
The most effective way to reduce taxes on a bonus is to direct a portion into pre-tax accounts. A traditional 401(k) contribution allocated to your bonus reduces your taxable income dollar-for-dollar for federal and state income tax purposes. Contributions to an HSA work the same way. Note that the 2026 401(k) contribution limit is $23,500 ($31,000 if you are 50 or older with catch-up contributions). Use our paycheck after 401(k) calculator to model specific scenarios.
