Since then, both retail and online wagering have been available, allowing anyone 21 years or older to place bets legally while physically located within state borders.

Our Review and Approval Process for Maryland Sportsbooks
At Sigma Play, we go beyond simply listing Maryland’s legal sportsbooks—we personally test, verify, and evaluate each platform before it earns a place on our site. Our goal is to make sure every sportsbook we feature is not only legitimate but also delivers a safe, enjoyable, and high-quality betting experience for Maryland players.
Each site undergoes a rigorous multi-step review designed around two core factors and our unique ‘How We Rate’ methodology, ensuring only the most reliable and well-regulated sportsbooks make the list.
Trust & Safety
At SiGMA, we confirm that each sportsbook holds an active license from the Maryland Lottery and Gaming Control Agency (MLGCA) and complies with the Maryland Sports Wagering Expansion Measure (2021). Our experts test every site’s security, payment encryption, and data-protection standards in line with our editorial guidelines, which outline how we review and rate operators with consistency and transparency. We also verify independent fair-play audits and ensure each operator supports Maryland’s responsible gambling requirements, including self-exclusion tools and deposit limits.
Player Experience
Every player’s experience matters when reviewing Maryland’s legal sportsbooks — and that starts with how well each platform performs across devices. Our review process looks at usability and performance on PCs, laptops, tablets, and smartphones, ensuring a consistent and smooth betting experience wherever you play.
For mobile betting apps, we test both Android and iOS apps to evaluate how easy they are to navigate, how quickly odds and markets load, and whether in-play features and cash-out options work without lag. We also assess design responsiveness, security during mobile payments, and how well location services function within Maryland’s legal boundaries.
This hands-on testing helps us highlight sportsbooks that deliver a reliable, seamless experience for Maryland bettors — from desktop to mobile.

Most Popular Sports and Bet Types in Maryland
Maryland’s sports betting scene is packed with variety, covering everything from major US leagues to international tournaments. While local fans enjoy a wide range of options, a few sports and bet types dominate the action across state-licensed sportsbooks.
Football (NFL & NCAA)
Football is king in Maryland. Fans passionately follow the Baltimore Ravens and often wager on NFL futures, point spreads, player props, and same-game parlays. College football also draws attention, especially matchups involving the Maryland Terrapins and Navy Midshipmen, both staples of NCAA Division I competition.
Basketball (NBA & NCAA)
While Maryland doesn’t host its own NBA team, many locals back the nearby Washington Wizards. Bettors love markets like moneylines, totals, parlays, and player props, especially during playoff season. College basketball betting is also popular, with schools such as Coppin State and Morgan State driving strong in-state fan support.
Baseball (MLB)
The Baltimore Orioles hold a special place in the hearts of Marylanders. MLB fans often explore live betting, futures, and prop wagers on key players and seasonal outcomes. Some sportsbooks even roll out exclusive promos when the Orioles hit the field.
Hockey (NHL)
Even without an in-state NHL team, Marylanders rally behind the Washington Capitals. Betting markets like futures, puck lines, and team props keep the excitement going each season—especially when the Caps are chasing another Stanley Cup run.
Tennis & Other Sports
Tennis betting thrives during the Grand Slams, particularly the US Open, where local star Frances Tiafoe draws plenty of support. You’ll also find strong markets for golf, soccer, and e-sports on most Maryland sportsbooks.
Bonuses and Promotions for Maryland Sports Betting
The best Maryland online sportsbooks—approved by the Maryland Lottery and Gaming Control Agency (MLGCA)—feature a wide range of secure, state-regulated bonuses and promotions. These offers cater to both new users and loyal bettors, helping enhance your overall betting experience. Below are the most common types of promotions you’ll find at licensed Maryland sportsbooks featured on Sigma Play.
Welcome Bonus
The Welcome Bonus is the main sign-up offer available to new Maryland players after registration and their first deposit. Depending on the sportsbook, this could come in the form of bonus credits, free bets, or cashback on initial losses. For example, many Maryland operators offer 100% deposit matches up to $1,000 or $50–$200 in free bets. You’ll typically need to meet wagering or minimum odds requirements before withdrawing any winnings, so it’s always best to review the bonus terms carefully before opting in.
Risk-Free Bet
A Risk-Free Bet, also known as a Second-Chance Bet, refunds your stake if your first wager doesn’t win. It’s one of the most popular offers for new users, often available right after registration. For instance, you might get up to $500 or $1,000 back in bonus credits if your initial bet loses. This bonus allows players to explore different betting markets—like moneylines, props, or parlays—without worrying about losing their entire first wager.
Deposit Match Bonus
The Deposit Match Bonus rewards players by matching a percentage of their first deposit with bonus funds. In Maryland, sportsbooks commonly offer matches ranging from 50% to 100%, usually capped between $250 and $1,000. For example, a 100% match up to $500 means a $500 deposit earns you an extra $500 in bonus credits. These funds are subject to rollover requirements (often 5x–10x) before you can withdraw any winnings, making this a great option for players planning to stay active.
No Deposit Bonus
A No Deposit Bonus gives players free credits or bets simply for signing up—no deposit required. Offers typically range from $10 to $50 in site credit, allowing new users to test the platform and place small bets risk-free. Though rare and usually smaller in value, these bonuses are a perfect way for cautious bettors to explore an operator before committing real money. Keep in mind that wagering and withdrawal conditions still apply.
Loyalty and VIP Rewards
The Loyalty and VIP Rewards programs in Maryland sportsbooks are designed for frequent players who wager regularly. Each bet you place earns loyalty points that can be redeemed for cashback, free bets, merchandise, or exclusive bonuses. VIP members may also gain access to personal account managers, higher withdrawal limits, priority support, and tailored promos. The more you bet, the higher your tier—and the better the rewards you unlock.
Disclaimer
All bonuses are available only to eligible players in Maryland. Terms, conditions, and wagering requirements apply.
Taxes on Maryland Sports Betting Winnings
All sports betting winnings in Maryland are treated as taxable income under both federal and state law. This means that whether you win from a single wager or accumulate profits over the year, you must report those earnings to both the IRS and the Maryland Comptroller’s Office when filing your annual tax returns.
Federal Tax on Winnings
At the federal level, gambling winnings are subject to a 24% withholding tax if you’ve provided your Social Security Number (SSN). If you don’t provide one, the rate can rise to 30%. Sportsbooks may issue a Form W-2G if your winnings exceed certain thresholds, or if federal withholding applies.
Maryland State Tax
Maryland applies a progressive state income tax, meaning the rate increases with your total taxable income. For most residents, the rate ranges from 2% to 5.75%, depending on earnings. Local counties and municipalities may also impose a small local income tax (typically between 2.25% and 3.20%), which is added on top of the state rate.
Example: If you win $50,000 from sports betting in Maryland and your total income places you in the highest state bracket (5.75%), your estimated tax liability would be:
Federal tax: $12,000 (24%)
Maryland state tax: $2,875 (5.75%)
Local tax (average 3%): $1,500
That’s a total of approximately $16,375 in combined taxes, leaving you with around $33,625 after taxes.
Licensed sportsbook operators in Maryland also pay a 15% tax on gross gaming revenue, which directly funds the Blueprint for Maryland’s Future Fund—a state initiative focused on enhancing public education.
As of August 2024, Maryland has collected over $100 million in total tax revenue from sports betting since its legal launch in December 2021, demonstrating how regulated wagering contributes meaningfully to public programs and state development.
Disclaimer
Tax situations can vary based on individual income, filing status, and other factors. It’s always best to consult a qualified tax advisor or accountant for guidance on reporting and paying taxes on your Colorado sports betting winnings.
