Legal basis

Proposition DD, approved by voters November 2019, authorizing sports betting and a 10% tax on net proceeds. Title 44, Article 30, C.R.S. (Limited Gaming Act), under which the Colorado Limited Gaming Control Commission and the Division of Gaming regulate casino gaming and sports betting. Daily fantasy sports licensed separately since 2016. Proposition JJ, approved 5 November 2024, removing the $29 million cap on retained sports betting tax revenue.

The state of Colorado has legalized sports betting, but not all forms of online gambling like online casinos. There are twelve licensed sportsbooks, with daily fantasy sports legal as well. The state doesn’t allow online casinos, while prediction markets are legal under federal law. Each of the licensed sportsbooks is tethered to mountain-town casinos.

Where You Can Bet in Colorado

You can bet in Colorado via one of the twelve licensed sportsbooks. Players should be aware that online casino gaming is not legal in the state.

The Twelve Licensed Sportsbooks

A total of twelve sportsbooks are licensed in the state of Colorado. These include:

  • Bally Bet
  • bet365 Colorado
  • BetMGM Colorado
  • DraftKings Colorado
  • FanDuel Colorado
  • Bet Monarch
  • BetRivers
  • Circa Sports
  • theScore Bet
  • Fanatics
  • Hard Rock Bet
  • Caesars

Each of these sports betting sites is tethered to licensed casino establishments, whether it’s Black Hawk, Cripple Creek, or Central City. This is also the reason why the market has twelve sportsbooks and not an open field. Check the full Colorado sportsbook comparison for a range of offers and terms.

DraftKings, FanDuel and bet365 in Colorado

DraftKings, FanDuel, bet365, and BetMGM all run online sportsbooks in the state of Colorado. They also offer daily fantasy sports. Their online casino components are not legal, because online casinos are not legal in the state.

What Is Not Available

Online casinos and online poker rooms are not legal in Colorado. The state currently has no legal framework for these establishments, meaning that no operator can run these games within.

Tax on Gambling Winnings in Colorado

Tax on Gambling Winnings in Colorado

Colorado State Tax on Winnings

Colorado has a flat tax rate of 4.40% that applies on gambling winnings. What this means is that no matter how much you win, you will pay 4.40% in taxes. In 2024, the rate temporarily dropped to 4.25% under the TABOR revenue-trigger mechanism. It later reverted back to 4.40% in 2025 and 2026. Any source that shows the rate with the dip is out of date.

What You Still Owe Federally

Federal tax applies on top of the state rate. Winnings reported on a W-2G form are withheld at a tax rate of 24%. The federal tax also depends on your tax bracket, which itself applies to all your income. This is general information, and not tax advice.

Pending Colorado Gambling Legislation

No Online Casino Bill Has Been Introduced

Colorado online casinos are not legal in the state. As of September 2026, there has been no online casino bill introduced in the state.

Proposition JJ and Sports Betting Tax

Proposition JJ was passed in Colorado in November 2024, with 76.3% in favor. What it did was remove a $29 million cap that proposition DD originally placed on sports betting tax revenue. Everything above that threshold was previously refunded to sportsbooks under TABOR. With the new Proposition, the state keeps all the tax instead. That additional revenue is directed to water projects. The state has no sweepstakes statute and no regulator enforcement campaigns, where it differs from most states where sports betting is legal.
