Assumptions
- Uses the 22% flat federal rate for bonuses up to $1,000,000 (37% above that is not modeled)
- This estimates withholding at bonus time, not your final tax liability after filing
How it's calculated
Federal withholding = bonus × 22%. Plus Social Security (6.2%) and Medicare (1.45%).

Frequently asked questions
Will I get some of this back as a refund?
Possibly — this is withholding at bonus time, not your final tax bill. Your actual tax on the bonus depends on your total year's income when you file.
