Frequently Asked Questions

How are bonuses taxed?

Employers can withhold at a flat 22% federal rate (37% for amounts over $1 million) or use the aggregate method which combines the bonus with your regular pay and withholds based on the combined amount. The flat rate is more common and simpler.

Will I get bonus tax back when I file?

Possibly. The 22% flat withholding is just an estimate. When you file your return, the bonus is taxed at your actual marginal rate. If your effective rate is lower than 22%, you will get a refund. If higher, you may owe more.

Is FICA tax applied to bonuses?

Yes. Bonuses are subject to the same FICA taxes as regular pay: 6.2% Social Security (up to the annual cap) and 1.45% Medicare. This is in addition to income tax withholding.
