Sports betting in Wisconsin is legal, but only in person at tribal casinos whose gaming compacts have been amended to authorize it. You cannot legally place a bet from your phone through a mainstream app like DraftKings or FanDuel, and no commercial sportsbooks operate in the state. One tribe runs a mobile app that works only while you are physically on its land. A bill that would open the door to statewide mobile wagering has passed both chambers of the Legislature and is sitting on the governor’s desk.
Where You Can Legally Place a Bet
Legal sports wagering is available only at tribal casino facilities that have an approved sports betting amendment to their state compact. Eight of Wisconsin’s 11 federally recognized tribes have secured those amendments, and the U.S. Department of the Interior has approved all of them.1Wisconsin State Legislature. Tribal Gaming in Wisconsin – Informational Paper 91 Having an amendment is not the same as running an active sportsbook, so some tribes are taking bets while others are still building out their operations.
Sportsbooks are currently operating at:
- Oneida Casino near Green Bay, which launched Wisconsin’s first sportsbook in November 2021
- Potawatomi Casino Hotel in Milwaukee, run by the Forest County Potawatomi
- St. Croix Chippewa casinos in Turtle Lake, Danbury, and Hertel
- Lake of the Torches Resort Casino, run by the Lac du Flambeau Band
You place wagers in person, either at a staffed counter or at self-service kiosks on the casino floor. Account funding usually happens at the casino cage. The Oneida sportsbook, for example, takes cash deposits only, with no credit cards, debit cards, wire transfers, or electronic transfers, and withdrawals have to be collected in person at the cage.2Oneida Casino Hotel. Sportsbook Terms and Conditions Policies vary by tribe, so call the specific casino before you drive out.
What You Can and Can’t Bet On
Tribal compacts allow wagers on professional sports, including the NFL, NBA, MLB, and NHL, along with certain non-sports events such as nationally televised award shows. You can place moneylines, point spreads, totals, parlays, futures, and props.
College sports are off the table entirely. The ban is not limited to Wisconsin teams; no college game from any state can be wagered on at a Wisconsin tribal sportsbook. Betting on elections and on events involving anyone under 18 is also prohibited.
The minimum age at every Wisconsin tribal sportsbook is 21.
Mobile Betting Is Mostly Off Limits
Statewide mobile sports betting is not legal in Wisconsin. You cannot sit at home and place a bet through DraftKings, FanDuel, BetMGM, or any similar app. The only mobile option in the state is the Oneida Nation’s app, and it is geofenced to Oneida land, which covers the casino properties and designated Oneida One-Stop travel centers. The moment you leave tribal land, the app stops accepting wagers.
Daily fantasy sports sit in a gray area. Wisconsin law does not specifically address DFS, and the state has not moved against the major operators, which continue to run under the position that fantasy contests are games of skill rather than gambling. No Wisconsin statute or court decision has resolved the question.
A Pending Bill Could Open Up Statewide Mobile Betting
Assembly Bill 601 would create a new carve-out in state law allowing a wager placed on a mobile device by someone physically located anywhere in Wisconsin, provided the server handling the bet is located on tribal land. The structure mirrors the model used in Florida.
The Assembly passed the bill unanimously, and the Senate followed in March 2026. The bill now sits with Governor Tony Evers. Evers has raised concerns about whether all 11 Wisconsin tribes support the measure; eight have publicly asked him to sign it. If it becomes law, residents could eventually place mobile bets from anywhere in the state through tribal-operated platforms, though the specifics would still have to be worked out in compact negotiations.
Why Wisconsin’s Rules Look This Way
Article IV, Section 24 of the Wisconsin Constitution tells the Legislature it “may not authorize gambling in any form” outside a short list of exceptions, and sports wagering is not one of them.3Wisconsin State Legislature. Wisconsin Constitution Article IV, Section 24 – Gambling The constitution also bars the state lottery from running any game where winners are picked based on a race or sporting event. Chapter 945 of the state statutes backs that up by criminalizing bookmaking.4Wisconsin State Legislature. Wisconsin Statutes Chapter 945 – Gambling
The route around all of that runs through federal law. The Indian Gaming Regulatory Act of 1988 lets federally recognized tribes offer Class III gaming, which includes sportsbooks, on tribal land once the tribe negotiates a compact with the state and the Department of the Interior signs off.5National Indian Gaming Commission. Indian Gaming Regulatory Act After the Supreme Court struck down the federal sports wagering ban in 2018, Wisconsin tribes began amending their existing compacts to add it. That is why your legal options start and end on tribal land.
Taxes on Your Winnings
Winning a bet creates a tax bill at both the federal and state level, even if the sportsbook never hands you a form.
Federal
All gambling winnings are taxable income on your federal return, no matter the amount. For sports wagering, the payer must withhold 24% of your net winnings (payout minus your wager) when two conditions are met together: net winnings exceed $5,000, and the payout is at least 300 times your wager. Starting in 2026, a Form W-2G is issued at $2,000 in winnings, with the threshold adjusted for inflation after that.6Internal Revenue Service. Instructions for Forms W-2G and 5754 Even smaller winnings still have to be reported.
Wisconsin
Wisconsin treats gambling income as taxable, but tribal sportsbooks generally do not withhold Wisconsin income tax from your payout. That means you may need to make quarterly estimated payments to the Department of Revenue to avoid penalties. Nonresidents with $2,000 or more in Wisconsin gross income, including gambling winnings, have to file a Wisconsin return on Form 1NPR.7Wisconsin Department of Revenue. Wisconsin Taxation of Gambling Income
Keep records of every bet, wins and losses alike. On your federal return you can deduct losses up to the amount of your winnings if you itemize. Wisconsin does not offer the same deduction to casual gamblers who do not keep adequate session-by-session records.7Wisconsin Department of Revenue. Wisconsin Taxation of Gambling Income
Why Offshore and Underground Books Are a Bad Bet
Because the legal footprint in Wisconsin is small, some bettors go to offshore websites or local bookmakers. That is illegal under Wisconsin law, and the practical risks are substantial. The FBI has warned that unregulated and offshore sportsbooks put consumers at risk of losing their money with no recourse, since those operators are not bound by the consumer protections that licensed U.S. sportsbooks follow. If the site refuses to pay, or disappears, there is no regulator to complain to and no legal mechanism to recover your funds. The FBI also notes exposure to extortion, identity theft, and money laundering schemes.8Federal Bureau of Investigation. Great Odds, High Risk: The FBI Encourages U.S. Bettors to Know the Risks of Illegal Gambling If you are betting anywhere other than a Wisconsin tribal sportsbook with an approved compact amendment, you are betting illegally.
Help if Betting Becomes a Problem
If wagering starts causing financial strain or feels hard to control, help is free. The Wisconsin Council on Problem Gambling runs a state helpline at 1-800-GAMBLE-5, with live chat at wi-problemgamblers.org. The national helpline, 1-800-MY-RESET, is also available around the clock.
For a firmer step, the Tribal-Wide Self-Exclusion Program lets you voluntarily ban yourself from participating tribal gaming venues through an online enrollment process. The Forest County Potawatomi was the first Wisconsin tribe to participate. Individual casinos may offer their own self-exclusion options too; ask at player services.
