Polished mobile app and the SGP+ builder, which lets bettors create same-game parlays faster and with better correlation pricing than at competitors.

Massachusetts Sports Betting FAQ
Is online sports betting legal in Massachusetts?
Yes. Online sports betting launched in Massachusetts in Mar 2023. The market is regulated by the Massachusetts Gaming Commission. Any sportsbook on this page is licensed by that regulator and accepts bets only from inside Massachusetts state lines (verified by geolocation).
How many sportsbooks operate in Massachusetts?
Massachusetts has 7 licensed online sportsbooks as of April 2026. We track 5 of them with active welcome bonuses on this page; the others are typically smaller regional operators or retail-only books.
What is the sports betting tax rate in Massachusetts?
Massachusetts taxes operators at 20% online / 15% retail. This is what the operator pays the state on revenue, not what bettors pay on winnings. Bettors pay federal income tax on net gambling winnings (24% withholding on large wins) plus any applicable Massachusetts state income tax.
Which sportsbook has the best welcome bonus in Massachusetts?
Headline dollar amounts vary across operators (Bet365's "$365 win-or-lose" is the largest single-figure offer; BetMGM's "$1,500 first bet" is the largest first-bet protection). Our editorial team ranks FanDuel the highest-rated overall in Massachusetts. Compare every offer in the table above to pick what fits your bankroll.
Can I use my Massachusetts sportsbook account in another state?
Yes for the major operators (DraftKings, FanDuel, BetMGM, Caesars, bet365). The same account works in any state where the operator is licensed; the app activates the correct state's odds, promotions, and payment methods based on your geolocation. You cannot bet from a state where the operator is not licensed regardless of your account residency.
What is the minimum age to bet on sports in Massachusetts?
21+ in Massachusetts. This matches the federal-default 21+ minimum used in most US sports betting states. You must verify your identity (full legal name, DOB, SSN) before placing any bets — this is a federal Know-Your-Customer requirement.
