FAQ

Why is the 24% withholding different from the tax shown?
The payer withholds a flat 24% upfront, but large winnings are taxed as ordinary income and usually fall in the top 37% bracket. Your actual federal tax is typically higher than the 24% withheld, so you may owe more at filing.
Does this include state taxes?
No. State taxes vary widely — some states have no income tax, others tax winnings heavily. This tool shows federal tax only; add your state tax separately.
Does this assume a lump sum?
Yes, it assumes the winnings are received as a single lump sum taxed in one year. Annuity payouts spread the income across years and can change the result. This is an estimate, not tax advice — consult a professional.
