Massachusetts Sports Betting Law Overview
For those wondering, can you bet in Massachusetts legally, the answer is yes. The legalization began with the enactment of Bill 5164, which is also known as the Massachusetts Sports Wagering Act, signed by Governor Charlie Baker on August 10, 2023. This legislation allows for both retail (in-person) and online sports betting in the state.
Moreover, online sports betting Massachusetts became legal on January 31, 2023, following the publication of the Massachusetts Sports Betting Catalog, which outlines approved events and options.
Legal Betting Age & Location Rules
The legal betting age in Massachusetts is 21 years old. To bet with regulated MA bookies, one needs to be within the state borders while doing so. You can open an account even if you are not within the state lines, but you can’t deposit or place a bet.

Massachusetts Gambling Taxes
Gambling winnings in Massachusetts are subject to a state income tax. The state requires that all gambling winnings be included in the taxpayer’s gross income and taxed at the rate of 5% plus a surcharge.
One important aspect of the Massachusetts online betting market is that gambling losses can only be deducted if you bet in a state-regulated and licensed venue. This means that if you gamble out-of-state or in an unlicensed sportsbook, any losses won’t count as tax deductibles.
Furthermore, non-residents who collect their rewards from state-regulated gambling businesses are required to pay tax on gambling winnings. This includes winnings from lotteries, casinos, slots parlors, pari-mutuel wagering, and other forms of gambling.
Top 5 Sportsbooks in Massachusetts Reviewed
We have curated a list of the top 10 best Massachusetts sports betting sites. But, we will be taking a closer look into the top 5. So if you want to know where you can bet on sports in Massachusetts and have a great time, keep reading.
1. BetWhale – Outright Odds and Lines Released Weeks in Advance
- Website: betwhale.ag
- Number of Sports:31
- Live Betting: ✅
- Same-Game Parlays: ✅
- Max Winnings Per Day: $2,500
One of the reasons why BetWhale is among the leading Massachusetss sports betting sites is the fact that they jump on the odds early, especially for major US leagues like the NFL, NBA, and MLB. For example, lines for the Chargers vs. Lions preseason 2025 Pro Football Hall of Fame game were already posted a full week before kickoff, while BetNow didn’t even have the event listed.
At the time of writing, BetWhale had the Lions at +150 on the moneyline with overtime included, closely matching Vegas’ opening lines. Meanwhile, BetOnline had them at -115, and the math is clear on who got the better value for bettors.
As for the welcome bonus, there’s solid value on the table, especially for crypto users. You can get a 200% match up to $6,000, or 100% up to $1,000 if you’re depositing in fiat. The offer can only be claimed once per account and comes with a 15x rollover, a $10,000 max win cap, and a $100 minimum deposit.
Pros
- Matches Vegas odds, includes overtime in moneyline
- Generous crypto bonus with high win cap of $10,000
- The betting lobby hosts 30+ sports

Cons
- Streaming limited to low-profile events only

- Website: www.betnow.eu
- Number of Sports: 10

BetNow gives horse racing the attention it deserves. First of all, there is a dedicated racebook covers action on 40+ domestic and international tracks. Secondly, there are flexible stakes, with a minimum wager of just $1 and payouts reaching up to $30,000. There’s also a 10% rebate on horse racing deposits, which adds a bit of value for regulars in the paddock.
Outside the racebook, BetNow runs a few solid promos worth noting. New crypto users can claim a 200% bonus by entering code CRYPTO200 during their first deposit. It only takes $5 to qualify, and the bonus caps at $1,000. Just keep in mind there’s an 18x rollover requirement, which is a bit on the higher side, but not unheard of in this space.
Speaking of bonuses, it’s the sportsbook rebate offer that shines the brightest. Every Monday, players get 2% back on net weekly losses (wins minus losses, minus any bonuses). It’s automatic, too, so no opt-in needed, as long as your account is verified and in good standing.
Pros
- Dedicated racebook with high $30k payout ceiling

3. BetOnline- Top Massachusetts Sportsbook With the Biggest Daily Odds Boosters and Parlays
- Website: www.betonline.ag
- Number of Sports: 29
- Live Betting: ✅
- Same-Game Parlays: ✅
- Max Winnings Per Day: $100,000
When you think of BetOnline, thinking of industry-leading daily odds boosts. There’s a full section dedicated to these enhancements, so the value is ripe for the taking there. We calculated that the average boost hovers around 20%, but there are moments where it jumps even higher. Take the Robert Whittaker vs. Reinier de Ridder UFC fight, where Whittaker to win by points went from +150 to +300. It’s a solid edge for value hunters.
Parlay fans will find plenty to work with. BetOnline offers over 20 ready-made Same Game Parlays each day, along with one of the most extensive prop menus around. From financial markets to political races and TV shows, the variety is second to none.
For sharper pricing, BetOnline boasts a reduced juice on NFL and dime lines for MLB games. That means the juice starts at just 10 cents instead of the usual 20, which can make a real difference over time.
Pros
- Daily boosted odds across key matchups
- 20+ Same Game Parlays available daily
- Massive prop betting menu across categories
- Reduced juice on NFL and MLB dime lines
Cons

4. BUSR – Maximum Daily Payout of $100,000
- Website: www.busr.ag
- Number of Sports: 31

New users at BUSR can kick things off with a Free Play bonus worth up to $1,500. It’s a 50% match on your first deposit, with the help of the code SPORTS50FP. Now, you do need to drop at least $100 to activate it, so it might be an offer for the high rollers.
Another area where where BUSR shines is in its NFL coverage. Outright odds are pretty competitive and are released quite early, so the bookie is a solid place for season-long plays, futures, and in-game action alike. We need to add live streaming to that mix, especially since it’s good for for major league.
Payouts are another plus, particularly for crypto users. BUSR processes Bitcoin withdrawals in under 24 hours on average, which is quicker than what most US-friendly sportsbooks manage. Plus, the max payout is set at $100,000 per transaction, so even if you are that high roller using the bonus, you’ll have a lot to look forward to.
Pros

5. BC.Game – Top Massachusetts Online Sportsbooks for eSports

BC.Game packs a mean punch when it comes to coverage. With over 40 sports available, the variety here is among the best in class. Soccer alone generates more than 1,100 events at any given time, encompassing both top-flight leagues and lower-tier competitions. But it’s the eSports section that really stands out.
Beyond staples like Counter-Strike, League of Legends, and Dota 2, you’ll find markets on more niche titles, such as Cricket 24, Teamfight Tactics, and Mobile Legends. It’s clear BC.Game leans into eSports as a major offering, not an afterthought.

As for promos, the welcome package spans your first four deposits and can reach up to $100,000 in BCD, the platform’s native crypto.

Sports & Leagues You Can Bet on in Massachusetts
Massachusetts has a wide range of sports to bet on, including football, basketball, ice hockey, and more. Bettors can place bets on professional leagues as well as college tournaments. Here are some of the best sports to bet in the state.
NFL, NBA, MLB, NHL
When it comes to betting on major US leagues, such as the NFL, NBA, MLB, and NHL, the sportsbooks we’ve reviewed leave nothing to be desired. Odds for these events are typically released earlier than for other sports, giving you more time to shop lines and place well-timed wagers.
Many of these sportsbooks also run sport-specific promos and boosted odds tied to marquee games. BetOnline, for instance, regularly features boosted props for key NFL or NBA matchups and even includes league-specific legs in its Mega Parlay, a rotating promo that blends top fixtures from MLB, NHL, NFL, and NBA.
College Sports Betting Rules
Regulated sports betting sites in Massachusetts are not allowed to offer college betting on teams from the state. Additionally, props on college players are also a no-go. However, these limitations do not apply to bookies regulated offshore, although the coverage is admittedly not as diverse.
Niche Sports (UFC, NASCAR, Golf, etc.)
For fans of niche sports like UFC, NASCAR, golf, and more, these sportsbooks offer robust coverage and features. Take, BetWhale, for instance. It stands out with sharp odds on NASCAR’s Head-to-Head matchups, while BetOnline takes UFC betting a step further by supporting Same Game Parlays, a rare feature in fight markets, letting you combine outcomes like method of victory, round betting, and moneyline picks within a single bout.
Massachusetts Sports Teams to Bet On
The Bay State boasts premium teams across America’s favorite sports, and the coverage on the bookies listed here doesn’t disappoint.
Boston Red Sox are a staple in Bay State sports culture, and for bettors, Red Sox games often come with sharp lines due to heavy local action and national interest, especially during American League East rivalry with the Yankees. The value usually doesn’t lie on moneylines, but it’s the player props that run the show.
The Celtics, with their NBA championship record of 18 titles, are led by Jason Tatum and have the highest aspirations coming into every season. Last season, they ranked second in the league for points in the game, with 121.80 per, so betting on over for total points seems like a good prospect.
The Bruins are always a contender in the NHL’s Eastern Conference, and the oddsmakers always offer good odds on moneylines or puck line options due to their playstyle packed with physicality, especially at home.
Boston College Eagles may not be an elite team of the NCAA Division I, but that doesn’t mean the support from the local crowd lacks. In fact, with their flying under the radar of bookmakers, bettors can find value in misplaced lines frequently.
Popular Bet Types & Betting Markets
Let’s take a closer look at some of the most common types of bets in Massachusetts online sportsbooks.
| Type of Bet | Description |
|---|---|
| Moneylines | Pick the winner of game |
| Spreads | Bet margin of victory or loss |
| Totals | A bet on combined points scored |
| Parlays | Multiple bets that all must win |
| Props | Bets on player or game stats |
| Futures | Long-term wager on the season outcome |
| Live Bets | Bets placed during a live game |

Other Legal Betting Options in Massachusetts
Sports betting Massachusetts platforms also offer a variety of options beyond traditional sports, including horse racing, DFS, and lotteries. Here are some of the other ways residents and visitors can legally place bets in the state.
Horse and Greyhound Racing
Horse racing and pari-mutuel wagering are legal in Massachusetts. The primary venue for live horse racing is the Plainridge Park Casino in Plainville, which covers harness racing from April to November.
As for greyhound racing, it is banned in Massachusetts, as per the 2008 Greyhound Protection Act, so the only option for wagering on greyhound racing are offshore betting sites that are not obligated to abide by the local laws.
Daily Fantasy Sports (DFS) Contests
Daily Fantasy Sports (DFS) have been legally recognized in the Bay State since 2016. The state is home to some of the biggest DFS giants, which operate outside of Boston. It’s a unique type of sports-adjacent entertainment that combines skill, a love of sports, and gaming, drawing many young Bay Staters to it.
eSports
eSports are all the rage in the sports betting world, with games such as League of Legends, Counter-Strike, and others commanding the attention of bettors across the state. You can bet on outcomes, maps, kills, and more, with hundreds of markets available.
Lottery
The Massachusetts lotteries attract hordes of casual gamblers. This type includes scratch cards, draw games like Mega Millions, Powerball, and of course, Keno. Given the high demand, the lotteries are a meaningful contributor to sports gambling Massachusetts revenue.
Deposits & Withdrawals at the Best Massachusetts Sportsbooks
Choosing the right payment option for sports betting in Massachusetts is crucial, as not only is security at stake, but also the availability of bonuses and other benefits.

Where to Bet In Person in Massachusetts
Online Sports Betting vs Retail Betting
The clash between online sports betting and its retail counterpart is one of convenience and preference. With online betting, you can place bets anytime, anywhere, often with just a few taps. It gives access to a wider range of markets, live betting features, odds boosts, and generous welcome bonuses.
That said, in-person betting has its own perks. The atmosphere at a retail sportsbook or casino is immersive and bolsters camaraderie, which online betting simply can’t deliver. Moreover, cash transactions are immediate, and there’s less risk of digital distractions or overspending.
Responsible Gambling
An enjoyable betting experience only comes from responsible gambling. Create a budget and stick to it. Don’t forget to use the tools to control it, like max deposits and self-imposed betting limits. If gambling starts to feel like a problem, don’t hesitate to seek support. For more info and resources, check out the links below.
