Lottery Tax Calculator: Lump Sum vs Annuity Take-Home After Taxes
Winning a lottery jackpot is the start of one big decision and one big tax bill. This lottery tax calculator handles both.
Enter the advertised jackpot — the headline number is always the annuity total — and the calculator shows your real take-home for the lump sum (cash value, roughly half the jackpot) and for the 30-year annuity.
It layers in the three taxes every US winner faces:
- the mandatory 24% federal withholding on prizes over $5,000
- the full federal income tax at brackets up to 37%
- your state's lottery tax rate
For a $500 million advertised jackpot taken as a lump sum, that means roughly $250 million cash value, about $92 million in federal tax, state tax of $0 to $27 million depending on where you live, and a net somewhere between $130 and $158 million.
Everything updates instantly so you can compare scenarios — different states, payout types, and cash-value ratios — before you ever claim a real prize.
