Sports betting in Wisconsin is legal, but only in narrow circumstances: you can place a wager in person at certain tribal casinos whose gaming compacts have been amended to allow it, and one tribe runs a mobile app that works only on its own land. Statewide online or app-based betting is not legal, though a bill that would change that passed both chambers of the Legislature in early 2026 and is waiting on the governor.
Where You Can Legally Place a Bet
Legal sportsbooks in Wisconsin operate only at tribal casino facilities whose compacts include the sports wagering amendment. Eight of the state’s 11 tribes have secured those amendments, and several are actively taking bets.
The Oneida Nation launched Wisconsin’s first sportsbook in November 2021 at its casino complex near Green Bay. The Forest County Potawatomi runs a sportsbook at Potawatomi Casino Hotel in Milwaukee. The St. Croix Chippewa offers sports betting at its casino locations in Turtle Lake, Danbury, and Hertel. The Lac du Flambeau Band operates a book at the Lake of the Torches Resort Casino. Having an approved amendment does not automatically mean a tribe is taking bets, so if you’re planning a trip, call ahead.
You place your bet in person, either at a staffed counter or a self-service kiosk on the casino floor. Account setup, deposits, and withdrawals typically happen at the casino cage. Rules vary by property: the Oneida sportsbook, for example, accepts only in-person cash deposits, with no credit cards, debit cards, wire transfers, or electronic transfers, and withdrawals must also be handled at the cage.1Oneida Casino Hotel.

What You Can and Cannot Bet On
The tribal compacts allow wagers on professional sporting events, including NFL, NBA, MLB, and NHL games, along with some non-sports events like nationally televised award shows. Standard bet types are available: moneylines, point spreads, totals, parlays, futures, and props.
College sports are off the table entirely. That restriction is not limited to Wisconsin schools. 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.
You must be at least 21 to place a bet at any Wisconsin tribal sportsbook, the same age required for other casino gaming at these properties.
Mobile and Online Betting
Statewide mobile sports betting is not currently legal. You cannot open DraftKings, FanDuel, or any other major sportsbook app in Wisconsin and place bets from your home.
The one exception is the Oneida Nation’s mobile app, which works only when you are physically on Oneida Nation land. That includes the casino properties and designated Oneida One-Stop travel centers. Step off tribal land and the app stops taking bets.
Daily fantasy sports sits in a legal gray area. Wisconsin law does not specifically address DFS, and the state has not moved against the major platforms, which operate on the theory that fantasy contests are games of skill rather than gambling. No Wisconsin statute or court ruling has definitively settled the question.
The Pending Statewide Mobile Betting Bill
Assembly Bill 601 would carve out a new exception in Wisconsin law to allow wagers placed by mobile device from anywhere in the state, as long as the server processing the bet sits on tribal land. That structure mirrors an approach used in Florida.
The Assembly passed the bill unanimously, and the Senate approved it in March 2026. It now sits on Governor Tony Evers’ desk. Evers has expressed concern about whether the bill has broad support among all 11 Wisconsin tribes; eight of the 11 publicly urged him to sign it. If he does, Wisconsin residents could eventually place mobile bets statewide through tribal-operated platforms, though implementation would still run through compact negotiations, and a rollout timeline has not been set.
Taxes on Your Winnings
A winning bet creates a tax bill at both the federal and state level, whether the sportsbook hands you a form or not.
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 (the payout minus your original wager) when two conditions are both met: the net winnings exceed $5,000, and the payout is at least 300 times the wager. Starting in 2026, the reporting threshold for a Form W-2G is $2,000 in winnings, adjusted annually for inflation going forward.2Internal Revenue Service. Instructions for Forms W-2G and 5754 Winnings below those thresholds still have to be reported.
Wisconsin
Wisconsin treats all gambling income as taxable, but tribal sportsbooks are generally not required to withhold Wisconsin income tax from your payout. The responsibility to pay falls on you. If no state tax is withheld, you may need to make quarterly estimated payments to the Wisconsin Department of Revenue to avoid penalties at filing. Nonresidents with $2,000 or more in Wisconsin gross income, including gambling winnings, must file a Wisconsin return using Form 1NPR.3Wisconsin Department of Revenue. Wisconsin Taxation of Gambling Income
Keep records of every bet, wins and losses. On your federal return, you can deduct gambling losses up to the amount of your winnings if you itemize. Wisconsin does not allow the same deduction for casual gamblers who do not maintain adequate session-by-session records.3Wisconsin Department of Revenue. Wisconsin Taxation of Gambling Income
Offshore Sites and Underground Bookmakers
Because legal options are limited to a few tribal casinos, some bettors turn to offshore sportsbook websites or underground bookmakers. Both are illegal under Wisconsin law. The FBI has warned that unregulated sportsbooks and offshore gambling sites put consumers at risk of losing their money with no recourse, since those operators are not held to the consumer protection standards licensed U.S. sportsbooks follow.4Federal Bureau of Investigation.

Offshore sites have no obligation to pay you out, no regulator to complain to, and no legal mechanism to recover your money if the site disappears. The FBI also notes that illegal betting can expose bettors to extortion, identity theft, and entanglement in money laundering schemes.4Federal Bureau of Investigation.

If Betting Starts Causing Problems
Free help is available if sports betting begins to cause financial strain or feel out of control. 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, connects callers to local resources around the clock.
For a more decisive 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 also offer their own self-exclusion options through player services.
