Question 1

Is a bonus taxed in Wyoming?

Accepted Answer

Not by the state. Wyoming has no income tax on wages, so there is no state withholding on a bonus. You still pay federal income tax (withheld at a flat 22% by most employers), 6.2% Social Security up to the $184,500 wage base and 1.45% Medicare.

Question 2

What rate does Wyoming withhold on bonuses?

Accepted Answer

Zero. Without a state income tax there is no state supplemental rate. The only income tax withheld from a Wyoming bonus is federal: 22% on supplemental wages up to $1 million in the year and 37% above that, unless your employer uses the aggregate method.

Question 3

Can I reduce the withholding on my Wyoming bonus?

Accepted Answer

The most direct way is a 401(k) deferral from the bonus, if your plan allows it: the deferred part is not subject to federal income tax withholding. When your employer uses the flat 22% federal rate, your Form W-4 does not change it; under the aggregate method it does. If you expect a large refund or bill, adjust your W-4 for the rest of the year rather than the bonus itself.

Question 4

Why was so much taken out of my bonus?

Accepted Answer

A bonus check usually loses 22% to federal income tax withholding, 7.65% to Social Security and Medicare, and your state's supplemental rate on top. That can add up to 30% to 40% of the bonus. The federal 22% and the state rate are withholding, not a separate bonus tax. When you file your return, the bonus is taxed as ordinary wages at your real bracket, and any over-withholding comes back as a refund.

Question 5

What is the federal bonus tax rate in 2026?

Accepted Answer

There is no separate federal bonus tax. For withholding, IRS Publication 15 (2026) lets employers withhold a flat 22% on supplemental wages such as bonuses and commissions, or add the bonus to a regular paycheck and use the normal tables (the aggregate method). Supplemental wages above $1 million in a calendar year must be withheld at 37%. Social Security (6.2% up to the $184,500 wage base) and Medicare (1.45%, plus 0.9% on wages above $200,000) apply as well.

Question 6

Does putting my bonus in a 401(k) lower the tax?

Accepted Answer

Yes, if your plan allows deferrals from bonuses. A traditional 401(k) deferral is not subject to federal income tax withholding, so the 22% applies only to the part you take as cash. Social Security and Medicare still apply to the full bonus. The 2026 employee deferral limit is $24,500 across all your paychecks, including any deferrals you already made this year.
