Here's What MD Does With $85.8M In Sports Gambling Tax Windfall

Legal sports gambling has resulted in a significant tax windfall for the Maryland treasury, according to recent data.

Maryland is one of 40 states, along with the District of Columbia, that have adopted some sort of legalized sports gambling since the 2018 U.S. Supreme Court decision striking down the Professional and Amateur Sports Protection Act.

Since then, the national state sales tax revenue from sports betting soared 382 percent, from $190 million in the third quarter of 2021, when data collection began, to $917 million in the most recent 2025 data available, according to the U.S. Census Bureau.

States have varying tax rates on sportsbook revenues, ranging from 6.75 percent in Iowa and Nevada to 51 percent in New Hampshire, New York and Rhode Island. Typically, the higher the rate, the larger the portion of a state’s total tax revenue that comes from sports betting.

Maryland taxes online sports bets at a rate of 15 percent.

In the calendar year 2024, online sports betting added $85,831,813 in tax revenue to Maryland coffers, according to the Tax Foundation, a nonpartisan tax policy think tank.

In general, states use sportsbook revenue to help fund public schools, road improvements, law enforcement, gambling addiction treatment or other dedicated uses.

In Maryland, sports betting tax revenue goes to the state’s Blueprint for Maryland’s Future Fund, which supports public education programs.
