5. Frequently Asked Questions (FAQ)

Q1: Why are bonuses taxed differently?
A: Bonuses are considered supplemental income and are typically withheld at a flat rate, often at your marginal tax rate rather than being averaged with regular income.

Q2: What is the typical withholding rate for bonuses?

A: Yes, if too much tax is withheld from your bonus, you'll receive a refund when you file your annual tax return, assuming you've overpaid overall.

Q4: Are there strategies to reduce bonus taxation?
A: Some employers allow bonus deferral to retirement accounts, which can reduce current tax liability. Consult a tax professional for personalized advice.

Q5: Does this calculator account for state taxes?
A: This calculator uses your marginal tax rate input. For complete accuracy, you may need to account for both federal and state marginal rates combined.
