Did the bonus tax rate change for 2026?

No. The supplemental wage withholding rate for bonuses under $1 million remains 22% for 2026. The 37% rate for amounts above $1 million also remains unchanged. The income tax brackets that determine your final bonus tax did shift slightly upward for inflation, as they do every year.

What is the difference between the flat method and aggregate method for bonus withholding?

The flat (percentage) method withholds 22% from the bonus check regardless of your income. The aggregate method adds the bonus to your most recent regular paycheck, calculates withholding on the combined amount using the standard tables, then subtracts what was already withheld. The aggregate method often results in higher withholding because the bonus appears to push your income into a higher bracket temporarily.

Can I reduce taxes on my 2026 bonus?

Yes. The most effective strategies include contributing the bonus directly to a pre-tax 401(k) if your plan allows it, timing deductible contributions (IRA, HSA) in the same year, or requesting your employer use the flat method instead of the aggregate method if they offer a choice. Any over-withholding is returned as a refund when you file.

2026 Withholding Rates

IRS Supplemental Wage Rates for 2026

The IRS classifies bonuses as supplemental wages and sets specific withholding rates employers must use. These rates determine how much tax is withheld from your bonus check — not how much tax you ultimately owe.

Flat Rate (Under $1M)

22%

Most common withholding method

Flat Rate (Over $1M)

37%

Mandatory for amounts above $1 million

Actual Tax Rate

10–37%

Your marginal bracket at filing

Social Security + Medicare on bonus

Withholding is not the same as tax owed. If your employer withholds 22% but your effective marginal rate is 12%, you will get the difference back as a refund when you file. If your marginal rate is 32%, you may owe additional tax. The withholding is just an advance payment.

Two IRS-Approved Withholding Methods

Employers must use one of two IRS-approved methods to calculate bonus withholding. The method your employer uses affects your take-home on bonus day but not your final annual tax bill.

Method	How It Works	Result	Best For
Flat (Percentage) Method	Withhold 22% flat from bonus check	Consistent, predictable	Separate bonus checks
Aggregate Method	Add bonus to last regular paycheck, calculate withholding on combined amount	Often higher withholding	Bonus included in regular paycheck

Example: $10,000 Bonus — Flat Method vs. Aggregate Method

Bonus amount$10,000

Flat method withholding (22%)$2,200

Aggregate method (if adds to $6,000 biweekly paycheck — ~28% effective)~$2,800

Social Security withheld (6.2%, if under wage base)$620

Medicare withheld (1.45%)$145

Approximate take-home (flat method)~$7,035

Strategies

How to Reduce Tax on Your 2026 Bonus

You cannot avoid paying tax on your bonus — it is ordinary income — but you can legally reduce the amount owed through timing and pre-tax contributions.

Contribute to a 401(k). If your plan allows, direct the bonus into your traditional 401(k). The contribution reduces taxable income dollar-for-dollar, up to the 2026 limit. Confirm with HR before the bonus is paid.
Fund an HSA. If you have an HDHP, maxing out your HSA in the same year reduces AGI and can offset the tax impact of a bonus.
Time charitable contributions. Making a significant donation in the year you receive a large bonus can offset the income if it pushes you into itemizing.
Ask about withholding method. Some employers give employees a choice of flat vs. aggregate. If your marginal rate is below 22%, ask for the flat method to reduce over-withholding (you will get a refund either way, but this improves cash flow).

FAQ

Frequently Asked Questions

What is the tax rate on bonuses in 2026?

Bonuses are taxed as ordinary income at your marginal federal tax rate in 2026. Employers withhold at the IRS supplemental rate of 22% for bonuses under $1 million and 37% for amounts above $1 million. Your actual tax rate depends on your total annual income and filing status.

Why does my bonus look so heavily taxed?

Two reasons. First, the 22% flat withholding is higher than the marginal rate for many workers in lower brackets — but you get that over-withholding back as a refund. Second, if your employer uses the aggregate method, withholding can be even higher temporarily because it treats the bonus as if you earn that amount every pay period. Your final tax is settled when you file.

Does FICA apply to bonuses in 2026?

Yes. Bonuses are subject to Social Security (6.2%) and Medicare (1.45%) withholding in addition to income tax withholding, as long as you have not already exceeded the Social Security wage base (~$180,400 projected for 2026). If you have hit the SS wage base by the time you receive your bonus, Social Security will not be withheld but Medicare still will.

Can I contribute my bonus directly to my 401(k)?

Most 401(k) plans allow bonus contributions, but it depends on your plan document. Check with HR before the bonus is paid. Many plans require an advance election change, and some only allow standard payroll deferral percentages. If you can contribute, it reduces your taxable income for the year.

Is a year-end bonus taxed differently than a mid-year bonus?

No. The tax rate is the same regardless of when in the year the bonus is paid. Withholding may differ slightly depending on the aggregate method calculation, but your total annual income determines your final tax. The only timing consideration is whether pushing income into a new calendar year affects your tax bracket, which only matters if the bonus spans December/January.
