Frequently Asked Questions
How are bonuses taxed?
Most employers use the flat supplemental rate: 22% federal withholding on bonuses up to $1 million, and 37% on amounts over $1 million. FICA (Social Security + Medicare) also applies. Your actual tax liability may differ at filing time.
Will I get some of the bonus tax back?
Possibly. The 22% flat rate is withholding, not your final tax. If your actual tax bracket is lower than 22%, you will get a refund when you file. If your bracket is higher, you may owe additional tax.
Is a bonus taxed differently than regular pay?
Bonuses are taxed as supplemental wages. The IRS allows employers to use either the flat 22% rate or the aggregate method (combining bonus with regular pay and withholding at your marginal rate).
