Take-home pay on a lump-sum prize in Idaho
The table applies the top federal rate of 37% plus 5.3% Idaho tax. Amounts are the cash (lump-sum) value you receive, not the advertised annuity jackpot.
| Cash prize | Federal (37%) | State | You keep |
|---|---|---|---|
| $1.00M | −$370,000 | −$53,000 | $577,000 |
| $10.00M | −$3.70M | −$530,000 | $5.77M |
| $100.00M | −$37.00M | −$5.30M | $57.70M |
| $500.00M | −$185.00M | −$26.50M | $288.50M |
| $1.00B | −$370.00M | −$53.00M | $577.00M |
Federal figure is the total owed at the top bracket. At claim time only 24% is withheld; the rest is due when you file. Smaller prizes can fall into lower brackets, so the real federal bill may be less.
Nonresidents must file in Idaho
The FAQ tells US residents living outside Idaho to claim as nonresidents and file an Idaho return the following April. A resident of Washington should account for Idaho tax even though Washington has no personal income tax.
The claim check is not the final federal result
The Lottery lists 24% federal withholding as well as 5.3% Idaho withholding. Our jackpot estimate uses a 37% federal top rate, leaving a 13 percentage point federal gap to plan for. Retain the claim paperwork and W-2G when filing.
