How Bonuses Are Taxed in 2026 — The Complete Picture
The IRS classifies bonuses as supplemental wages — compensation paid in addition to regular salary. Supplemental wages follow different withholding rules than regular pay. There are two IRS-approved methods for withholding federal bonus tax from a bonus, plus FICA taxes that apply to every bonus regardless of method. Understanding all three layers shows exactly why your after-tax bonus is smaller than expected.

Why Your Bonus Feels Taxed at 40% — The Withholding Myth
The most common bonus tax misconception: workers believe bonuses are taxed at a special high rate — sometimes 40% or more. The reality is more nuanced. What feels like 40% is the sum of multiple withholding layers — none of which is your actual final tax rate.

Percentage Method vs Aggregate Method — Which One Applies to You
Your employer chooses the withholding method — you do not. The method depends on how the bonus is paid. Understanding the difference shows why two employees earning the same bonus amount can take home different net amounts.

FICA Taxes on Bonuses — Social Security and Medicare 2026
FICA taxes apply to bonuses exactly the same as regular wages. There is no exemption. The Social Security and Medicare portions are calculated on the gross bonus amount regardless of which income tax withholding method your employer uses. One important exception: if your year-to-date wages already exceed the $184,500 Social Security wage base before the bonus is paid, zero Social Security tax is withheld from the bonus.
| FICA component | Rate | Wage base | On $10K bonus | Exception |
|---|---|---|---|---|
| Social Security | 6.2% | $184,500 | $620 | $0 if YTD wages already > $184,500 |
| Medicare | 1.45% | No cap | $145 | No exception — applies to every dollar |
| Additional Medicare | 0.9% | $200K single | Varies | Employee only — employer begins withholding at $200K YTD |
| Total FICA (most workers) | 7.65% | — | $765 | Below SS wage base, no additional Medicare |

How to Reduce Bonus Tax — Legal Strategies 2026
You cannot choose a lower withholding rate for your bonus — the IRS sets the rules and your employer applies them. But several legal strategies reduce your actual tax liability or optimize when and how Social Security applies to your bonus.
| Strategy | How it works | Federal tax saving on $10K bonus (22% bracket) | Eliminates FICA? |
|---|---|---|---|
| Defer bonus to traditional 401k | If employer allows — reduces federal & state taxable wages | $2,200 (22% bracket) | No — FICA still applies |
| Receive bonus after SS wage base hit | Once YTD wages exceed $184,500, no SS withheld on bonus | $620 SS saving | Partial — SS eliminated |
| Bunch charitable donations in bonus year | Large bonus year — itemize deductions to offset income | Varies by donation amount | No |
| HSA contribution from bonus (Section 125) | If employer allows — reduces both income tax AND FICA | $2,200 federal + $765 FICA | Yes — if Section 125 |
| Verify W-4 filing status is correct | MFJ reduces aggregate method withholding vs Single status | Reduces over-withholding | No |
| Accept lower withholding? No — impossible | Employees cannot choose withholding rate on bonuses | N/A | N/A |
Common Bonus Tax Mistakes
Thinking 22% is your final bonus tax rate
The 22% is withholding only. Your actual federal tax on the bonus is your marginal rate. If you are in the 12% bracket, you get a 10% refund. If you are in the 32% bracket, you owe 10% more at filing.
Believing 401k deferrals eliminate all bonus taxes
A 401k deferral removes the bonus from federal and state income tax but FICA (Social Security + Medicare) is still calculated on gross wages before the 401k deduction. On a $10,000 bonus deferred to 401k, you still owe $765 in FICA.
Spending the full gross bonus before taxes
Budgeting around the gross bonus amount instead of the after-tax amount is the most common mistake. On a $15,000 bonus in California, net take-home is approximately $9,018 — not $15,000. Always budget from the net figure, not the gross announcement.
Confusing withholding method with tax rate
The aggregate method does not mean you pay more tax — it means more is withheld upfront. If the aggregate method withholds 28% and your actual marginal rate is 24%, you get a refund. The withholding method changes timing, not final tax liability.
Bonus Tax Calculator — Frequently Asked Questions
How is a bonus taxed in 2026?
Bonuses are supplemental wages taxed with a flat 22% federal withholding (percentage method) for separate bonus checks under $1 million, or at your marginal bracket rate (aggregate method) when combined with your regular paycheck. FICA also applies: Social Security 6.2% up to the $184,500 2026 wage base, and Medicare 1.45% on every dollar. State supplemental withholding rates add 0% to 11.62% depending on your state. Combined total withholding typically ranges from 30% in no-tax states to 42% in high-tax states like New York. The 22% is not your final tax rate — your actual tax is reconciled at filing.
What is the bonus tax rate for 2026 — the 2026 federal bonus tax rate?
The 2026 federal supplemental wage withholding rate is 22% for bonus amounts under $1 million. Bonuses over $1 million trigger mandatory 37% withholding on the excess. These rates were confirmed for 2026 under OBBBA (P.L. 119-21, signed July 4, 2025) which permanently extended the individual income tax rates. Your actual final federal income tax rate on the bonus is your marginal bracket rate — which may be higher or lower than 22% depending on your total annual income.
Why does my bonus feel taxed at 40%?
Because combined withholding genuinely reaches 30–42% once all layers are added. Federal 22% + FICA 7.65% + state tax (0–11.62%) = 29.65% minimum in Texas, 39.88% in California, 41.27% in New York. This is withholding — not final tax. Your actual federal tax on the bonus is your marginal rate, which could be 12%, 22%, or 24%. Over-withheld amounts come back as a refund when you file. Use the calculator on this page to see your exact combined withholding by state.
What is the difference between percentage method and aggregate method?
The percentage method (flat 22%) is used when the bonus is paid as a separate check. Simple, predictable, always 22% federal. The aggregate method is used when the bonus is added to your regular paycheck — your employer calculates withholding on the combined total wages, which can produce a higher rate if the combined amount pushes into a higher bracket. The aggregate method often over-withholds relative to your true tax rate, resulting in a refund. Neither method changes your actual annual tax owed — only when and how much is held in advance.
Do bonuses get taxed at 22% or my normal tax rate?
Withholding is 22% (percentage method) or your marginal rate (aggregate method). Your actual final tax on the bonus is your ordinary marginal rate based on total annual income. If you earn $50,000 salary plus a $10,000 bonus, your total income is $60,000. After the $16,100 standard deduction, taxable income is $43,900 — taxed at 10% on the first $12,400 and 12% on the rest. Your effective rate on the bonus is approximately 12%. The 22% withholding over-collected by $1,000 which you recover as a refund.
Can I reduce the tax on my bonus?
Yes — two main strategies work. (1) Defer your bonus to a traditional 401k if your employer allows it. This eliminates federal and state income tax on the deferred amount (but FICA still applies). The 2026 401k limit is $23,500 ($31,000 if age 50+). (2) If your year-to-date wages will exceed $184,500 before the bonus is paid, the 6.2% Social Security tax does not apply to the bonus — saving $620 per $10,000 bonus. You cannot instruct your employer to use a lower withholding rate or skip FICA on a bonus.
Is bonus income taxed differently than salary?
In terms of your final annual tax liability — no. A bonus is ordinary income subject to the same federal brackets as salary. The difference is only in how withholding is calculated during payroll. Salary uses the standard W-4 percentage method tables. Bonuses use either the 22% flat supplemental rate or the aggregate method. But when you file your tax return, all income — salary, bonus, commissions, overtime — is combined and taxed at the same progressive rates. Any withholding difference is reconciled through a refund or additional payment.
How do I calculate my after-tax bonus — how to calculate bonus tax?
Using the percentage method: Net bonus = Gross minus (22% federal) minus (6.2% Social Security, if below $184,500 YTD) minus (1.45% Medicare) minus (state supplemental rate). Example: $10,000 bonus in Texas — federal $2,200 + SS $620 + Medicare $145 + state $0 = $2,965 withheld. Net take-home = $7,035. Same bonus in California: add $1,023 state. Net = $6,012. Use the bonus tax calculator above for your exact figures including your specific state and FICA situation. For the full paycheck impact, see the paycheck calculator.
What are the state bonus tax rates for 2026?
State supplemental withholding rates on bonuses in 2026 range from 0% (Texas, Florida, Nevada, and 6 other no-income-tax states) to 11.62% (New York state) and 10.23% (California). Other notable rates: Oregon 8%, Minnesota 6.25%, Virginia 5.75%, Illinois 4.95%, Georgia 5.09%, Colorado 4.4%, North Carolina 4.25%, Michigan 4.25%, Mississippi 4%, Ohio 2.75%, Indiana 2.95%, Kentucky 3.5%, Arizona 2.5%. These are withholding rates — your actual state tax on the bonus is your marginal state rate, which may be higher or lower.
