Flat vs. Aggregate Method
Most employers use the flat 22% supplemental rate for bonuses under $1M. The aggregate method combines your bonus with your regular pay to calculate withholding based on your actual tax bracket. Your actual tax liability is determined when you file your return — these are withholding estimates only.

How It Works
The Bonus Tax Calculator helps you understand how much of your bonus will actually end up in your pocket after taxes. Bonuses are often taxed at a higher rate than regular paychecks, and this calculator ensures you're not surprised by the net amount.
This calculator estimates the tax withholding using the supplemental wage tax rules, which typically involve a flat 22% federal withholding rate for bonuses under a certain threshold ($1 million) or an aggregate method if paid with regular wages. State and local taxes are then applied based on your location and relevant tax brackets.
Remember that this is an estimate; your actual tax liability might differ based on your overall income and deductions. A common mistake is assuming bonuses are taxed the same as regular wages, which can lead to a lower-than-expected net bonus.
Example: $5,000 Bonus
- 1 Input a bonus amount of $5,000, assuming a federal supplemental withholding rate of 22% and an estimated blended state/local tax rate of 5%.
- 2 Federal Withholding: $5,000 * 0.22 = $1,100. State/Local Withholding: $5,000 * 0.05 = $250. Total Withholding: $1,100 + $250 = $1,350.
- 3 Your estimated net bonus after taxes would be $5,000 - $1,350 = $3,650.
- 4 Even with a seemingly large bonus, a significant portion goes towards taxes. This calculator helps you manage expectations and plan your finances accordingly.
