Biggest Wisconsin Lottery Winners: Notable Jackpots, Tax Rules & Claiming Prizes

April 3, 2026  ·  6 min read  ·  News

Wisconsin on the National Stage

Wisconsin is the 20th most populous state, but it has produced some of the country's most memorable lottery wins. The state has seen major Powerball and Mega Millions jackpot winners over the years, alongside a steady stream of in-state Megabucks and SuperCash! winners.

Megabucks and SuperCash! Produce Frequent Winners

Because Megabucks is exclusive to Wisconsin, every jackpot winner is a Badger State resident. The rolling jackpot format means prizes can grow into the millions before someone hits. Meanwhile, SuperCash! takes a different approach: its fixed $350,000 top prize means the game produces winners more frequently than rolling-jackpot alternatives, since the prize pool never needs to accumulate.

What Winners Actually Keep — Tax Math

Wisconsin applies a progressive state income tax ranging from 3.54% to 7.65%. Combined with the 24% federal withholding, winners should expect an effective tax rate of roughly 31% to 32% depending on total income.

Wisconsin Winners Cannot Stay Anonymous

Under Wisconsin law, lottery winners cannot remain anonymous. The winner's name, city of residence, and prize amount are all public record. Some winners attempt a partial workaround by claiming through a trust or LLC, but the trust name itself becomes the public record — it does not guarantee full anonymity. This is worth considering before you buy your next ticket.

How to Claim a Prize

Winners have 180 days from the draw date to claim their prize. Prizes under $600 can be claimed at any authorized retailer. Prizes of $600 or more require a claim form and can be submitted by mail or in person at the Wisconsin Lottery headquarters in Madison. Prizes of $599 or more trigger tax reporting, and prizes of $2,000 or more are subject to automatic state withholding.
