Frequently Asked Questions

Why 22%?
22% is the IRS's flat federal supplemental wage withholding rate commonly applied to bonuses under $1 million — it's a withholding rate, not necessarily your final tax rate, which is reconciled when you file.
Does this include state tax?
Only if you enter a state withholding rate — it defaults to 0% since rates vary by state.
What inputs does the Bonus Calculator need?
You'll need to provide: Bonus amount, Federal withholding rate (%), State withholding rate (%). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
