The bill introduces new legal language focused on the financial reporting and taxation of gaming and sports wagering revenues from various casinos, including Encore Boston Harbor, MGM Springfield, and Plainridge Park Casino. It mandates detailed monthly financial data from June 2015 through August 2025, covering metrics such as total coin-in, gross gaming revenue (GGR), hold percentages, payout percentages, and state tax collections. A significant insertion is the specification of a 15% excise tax rate on sports wagering revenues, which aims to enhance the state's revenue from this growing sector. The bill also emphasizes the importance of transparency and accountability in the management of these revenues, particularly in light of fluctuations due to external factors like the COVID-19 pandemic.

Additionally, the bill outlines the financial performance of various sports betting operators, including Caesars, ESPN-Bet, Bally's, and DraftKings, detailing their monthly revenues and tax accruals from March 2023 through August 2025. It specifies metrics such as retail tax, monthly handle, monthly win, and federal excise tax, while also highlighting a cumulative total of $8,683,351,076.51 generated from sports wagering across all operators. The new provisions aim to ensure accurate reporting and compliance with tax obligations, ultimately benefiting state revenue through effective monitoring and regulation of the sports wagering industry.
