Notable Iowa Lottery Wins
As the birthplace of Powerball, Iowa has a deep history with lottery jackpots. The state has produced numerous significant winners since 1985, including multiple Powerball jackpot claims. Iowa's central role in the Multi-State Lottery Association means its players have had access to major multi-state games from the very beginning.
Powerball and Mega Millions Winners
Iowa's biggest lottery wins have come from Powerball and Mega Millions. With Powerball originating in Iowa in 1992, the state's players have had more than three decades of shots at the game's massive jackpots. Notable Iowa Powerball winners have claimed prizes in the hundreds of millions. Mega Millions has also delivered significant wins since becoming available in Iowa. For strategy resources, see our Powerball Guide and Mega Millions Guide.
Lotto America Winners
Lotto America, with its better overall odds compared to Powerball and Mega Millions, produces jackpot winners more frequently. The game's smaller but still significant jackpots (starting at $2 million) create a steady stream of winners. The All Star Bonus multiplier also boosts non-jackpot prizes, increasing the total payout across all tiers.
Claiming Prizes in Iowa
Iowa lottery prizes must be claimed within 365 days of the drawing date — one of the more generous claim periods among U.S. lotteries. Prizes up to $600 can be claimed at any licensed lottery retailer. Prizes over $600 require a claim form and can be submitted at Iowa Lottery offices in Clive (Des Moines area) or by mail. Iowa allows winners to remain anonymous for prizes over $1 million.
Taxes on Iowa Lottery Winnings
Iowa has a 3.8% state tax on lottery winnings, one of the lower rates in the country. Federal withholding of 24% applies to prizes over $5,000, bringing the combined withholding to 27.8% for larger prizes.
