Why is so much tax taken out of my bonus?

Bonuses use the IRS flat "supplemental wage" withholding rate of 22% rather than your normal paycheck rate, which can look high if your marginal rate is below 22%. It is only withholding — if too much is withheld, you get it back when you file your annual return.

Alaska Bonus Tax Calculator 2025

A bonus is a supplemental wage, and it is taxed differently from a normal paycheck. The federal government withholds a flat 22% on supplemental wages up to $1,000,000 in a year (37% on anything above that), plus FICA. Alaska levies no state income tax, so the only deductions from a bonus are the federal 22% supplemental rate and FICA (Social Security + Medicare).

Enter your bonus below. The calculator shows federal supplemental withholding, Social Security (6.2% up to the $176,100 wage base) and Medicare (1.45%, plus 0.9% above $200,000), the Alaska state portion, and your real take-home. Everything runs in your browser — no amounts or personal data are transmitted.

Important: Alaska has no state individual income tax, so no state tax is withheld from a bonus. Verify the current figure with the Alaska Department of Revenue.
