美国奖金按多少预扣？What withholding rate applies to a US bonus?
美国联邦所得税对补充工资（奖金）可选用 22% 的统一预扣率，单人全年补充工资超过 100 万美元的部分按 37% 预扣（来源：IRS Publication 15 (2026)，irs.gov/pub/irs-pdf/p15.pdf）。这只是联邦预扣，不含州税和 FICA；本页不会自动套用，需要你自己填写。For US federal income tax, employers may withhold a flat 22% on supplemental wages such as bonuses, and 37% on an employee's supplemental wages above $1 million in the year (source: IRS Publication 15 (2026), irs.gov/pub/irs-pdf/p15.pdf). This is federal withholding only — no state tax or FICA — and the page never applies it automatically; enter it yourself.
