Frequently Asked Questions
Why are bonuses taxed at 22%?
The IRS requires employers to withhold a flat 22% on supplemental wages (bonuses, commissions) up to $1 million using the percentage method. This is a withholding rate, not a separate tax rate. Your actual tax depends on your total annual income and bracket.
Will I get some bonus tax back as a refund?
Possibly. If the 22% flat withholding exceeds your actual marginal rate, the excess will be refunded when you file your tax return. Conversely, if your marginal rate is higher than 22%, you may owe additional tax.
Are bonuses over $1 million taxed differently?
Yes. The portion of supplemental wages exceeding $1 million in a calendar year is subject to a mandatory 37% federal withholding rate instead of the standard 22%.
