FAQ - ME Sports Betting Bonuses
Is online betting legal in Maine?
Yes. Online sports betting was officially legalized in Maine in 2023, but only the four tribal casinos may offer mobile betting licenses. Currently two options are available in the state:
Are online casinos legal in Maine?
Regretfully, real-money online casinos are currently not legal in Maine.
Does Maine allow international online gambling sites?
Yes, Caesars and DraftKings are available in the state. There are also options like Kalshi (prediction markets) and Fliff (social/sweepstakes) for players looking for new bonuses to play with.
What's the legal gambling age in Maine?
- 21+ for online sportsbooks, retail betting and tribal casinos.
- 18+ for lotteries, bingo, horse racing etc.
- 18+ for social sportsbooks, predictions and fantasy.
Why are only DraftKings and Caesars available in ME?
Maine has four recognized Native American tribes: The Houlton Band of Maliseet Indians, Mi’kmaq Nation, Penobscot Nation, and Passamaquoddy Tribe. These tribes have exclusive rights to offer online sports betting in the state. Each tribe is allowed to partner up with one sportsbook operator. This means that Maine has the possibility for four online sportsbooks.
The Passamaquoddy partnered up with DraftKings, but the three remaining tribes all chose to partner with Caesars. This means that all four partnership slots are taken, even though there is only two sportsbooks available.
Does Maine impose a tax on gambling?
There is no specific gambling tax, but gambling profits count as taxable income in Maine. The state does not have a flat rate, but the rate is capped at 7.15%. Keep in mind that federal tax is always applied to gambling winnings.
Visitors to the state are also required to file a Maine tax return and submit their gambling winnings. Depending on the state of residency, they may also be required to pay taxes in their home-state.
