How It Works
Bonuses are taxed as supplemental income. Employers can withhold at a flat 22% federal rate (37% for amounts over $1 million) or use the aggregate method, which combines your bonus with regular pay to determine the marginal tax rate. The aggregate method often results in higher withholding for high earners but may be more accurate. Either way, your actual tax is settled when you file your return.
