Estimated bonus in hand
Employers withhold federal tax on bonuses at a flat 22% (37% on any amount over $1 million), plus 7.65% FICA and state tax where applicable. On a $10,000 bonus in a no-tax state, that leaves roughly $7,035 in hand. The 22% is only withholding — your final tax is settled at your normal rates when you file.

Why bonuses feel over-taxed (they aren't)

Bonuses are "supplemental wages," and most employers withhold federal tax on them at a flat 22% (the percentage method), regardless of your actual bracket. If your real marginal rate is 12%, that 22% withholding is too high — but you get the difference back as a refund when you file. If you earn enough that your marginal rate is 32% or more, 22% withholding is actually too low, and you may owe at filing time.

The key idea: withholding is a prepayment, not the final tax. A bonus is ultimately taxed as ordinary income at your normal marginal rates. The flat 22% only determines how much is taken upfront. For bonuses above $1 million, the mandatory federal withholding rate on the excess is 37%.

Frequently asked questions

How much tax is taken out of a bonus in 2026?

Most employers use the percentage method: a flat 22% federal withholding on bonuses up to $1 million (37% above), plus 6.2% Social Security (if you're under the $184,500 wage base), 1.45% Medicare, and your state's rate. Total withholding typically runs 29–40% depending on state.

Why was my bonus taxed at 40%?

It wasn't taxed at 40% — it was withheld at a combined rate that can approach 40% once you stack 22% federal, 7.65% FICA, and a high-tax state. Your true tax on the bonus is your ordinary marginal rate; excess withholding returns as a refund when you file.

Can I reduce taxes on my bonus?

The main levers: direct part of the bonus into your 401(k) (reduces taxable income, subject to the annual contribution limit), fund an HSA if eligible, or — if your employer allows — defer the bonus to a year when you expect a lower bracket. You can't avoid FICA on a cash bonus.

Is the 22% bonus rate mandatory?

No. Employers may instead use the aggregate method — adding the bonus to a regular paycheck and withholding per your W-4, which often takes out more upfront. The flat 22% percentage method is simply the most common choice for separately-paid bonuses. Above $1 million, 37% withholding on the excess is mandatory.
