Massachusetts recorded $153.8 million in taxable gaming revenue in September 2026, with taxes collected reaching $38.4 million, according to the Massachusetts Gaming Commission (MGC).
Casino gross gaming revenue totalled around $82.69 million across Encore Boston Harbor, MGM Springfield and Plainridge Park Casino. Sports wagering contributed roughly $71.19 million in taxable revenue across seven online or mobile licensees and three retail licensees. August’s combined taxable gaming revenue was $149 million.
Encore Boston Harbor Leads Casino Revenue And September Tax Payments
Encore Boston Harbor generated $46 million in table and slot revenue, followed by MGM Springfield with $21.9 million and Plainridge Park Casino with $14.6 million.
Tax payments followed a different ranking. Encore contributed $11.5 million, while Plainridge paid $7.1 million despite recording the lowest casino revenue. MGM Springfield contributed $5.4 million.
Plainridge’s Higher Tax Rate Explains Its Larger Relative Contribution
As a Category 2 slots facility, Plainridge pays 49% of gross gaming revenue in tax. Of the amount collected, 82% goes to Local Aid and 18% to the Race Horse Development Fund. MGM Springfield and Encore are Category 1 resort casinos taxed at 25%, with proceeds distributed among designated state funds.
Since the properties opened, the MGC said “the Commonwealth has collected approximately $2.55 billion in total taxes and assessments from the casino operations of PPC, MGM, and Encore”.
Online And Retail Sportsbooks Operate Under Different Tax Categories
Encore, MGM Springfield and Plainridge hold Category 1 sports wagering licences, allowing retail sportsbooks at their properties. Their taxable sports wagering revenue is subject to a 15% rate.
Category 3 licensees can offer mobile or online sportsbooks and pay 20%. These operators are Bally Bet, BetMGM, Caesars Sportsbook, DraftKings, Fanatics, FanDuel and theScore Bet. Different licensing categories therefore shape both operating permissions and taxation.
Sports Wagering Taxes And Assessments Exceed $514 Million Since Launch
Retail sports wagering began on 31 January 2023, followed by online operations on 10 March 2023. Since launch, the MGC said “the Commonwealth has collected about $514.58 million in total taxes and assessments from licensed operators’ sports wagering operations”.
September’s report therefore records both current revenue performance and cumulative public receipts from the state’s licensed casino and sports wagering businesses.
Massachusetts’ results show why revenue rankings alone do not explain operators’ tax contributions. Different rates across casinos and sportsbooks affect receipts, as Plainridge’s position demonstrates. Future comparisons should distinguish casino gross gaming revenue from taxable sports wagering revenue.
