Its best month came in November 2021, when the state earned nearly $2 million in taxes.

• Betting Taxes

The Internal Revenue Code sets that sportsbooks must pay 0.25% tax on betting handles. There is an additional $50 tax for every employee involved in taking wagers. A state tax of 10% is currently in place for sportsbook operators, which is considerably lower than the 51% New York sportsbooks must pay.

Colorado Sports Betting Background

The state established the Colorado Lottery in January 1983, and in 1990, restricted casino gambling became legal thanks to the Colorado Limited Gaming Initiative. The law only allowed maximum bets of $5, and casinos couldn’t stay open for 24 hours.

John Hickenlooper made greyhound racing illegal. However, the state saw no sports betting legislation put forward until 2019.

Who Oversees Sports Betting in Colorado?

The (CLGCC) enforces state sports betting laws and regulations by issuing fines and collecting taxes. It also administers the state’s three gambling licenses: sports betting operator, master license, and internet sports betting operator. While the Gaming Division of the Colorado Department of Revenue assists the CLGCC, the latter has the final say on all matters.
