Is Sports Betting Legal In Colorado Today?

Yes, sports betting is legal in Colorado. Voters approved the legalization of both retail and online sports betting in a referendum carried out during the November 2019 election. Sports betting legislation then came into immediate effect and the industry launched in May of 2020. 

Colorado Sports Betting Legal Timeline

When the U.S. Supreme Court struck down the federal ban on single-event sports wagering in 2018, this gave individual states the power to pass their own legislation on sports betting. One of the first to take advantage of the ruling and since launching, Colorado sports betting apps and its regulated market have become one of the busiest and most competitive in the United States.

In April 2019, Colorado Rep. Alec Garnett introduced HB 1327 that would allow for a ballot measure giving voters their say on the legalization of both mobile and retail sportsbooks in Colorado.

A month after the bill was passed by lawmakers, Gov. Jared Polis signed it into law. All that was left now was for the electorate to decide the bill’s fate. 

Voters Approve Sports Betting | November 2019

Colorado Proposition DD is passed by the electorate in a voter referendum. This meant that the bill would go into effect in six months. In the meantime, the state’s 33 casinos could apply for licenses to offer retail and online sports betting.

Legal Landscape of CO Sports Betting

The rules here are either common sense or they are there to protect bettors and sportsbooks – but they could be both. Read these over before you begin sports betting in Colorado.

Key Colorado Sports Betting Rules, Laws & Regulations

Sports betting is a thriving industry in the state of Colorado and one that is constantly evolving. This is great news for CO sports bettors as it means that regulations, rules and laws are always under intense scrutiny. For example, in recent months, the state government has introduced and passed into law the Responsible Gaming Grant Program. This allows support and research groups to seek funding for their programs if those programs help toward creating a positive gaming environment and encourage responsible gaming. 

When it comes to scrutiny of the regulation of the industry, the state government is extremely vigorous. A recent audit carried out by Colorado's Office of the State Auditor revealed that there were some issues with how the industry is regulated. As a result, there will likely be some changes to how license holders are approved, plus other regulatory procedures. This oversight of the regulator offers assurance to bettors that the state government does all it can to protect its residents. 

Current Laws Governing Colorado Sports Betting

State laws on sports betting are quite complex for operators but rather simple when it comes to Colorado bettors. For example, here are some key rules everyone must know when betting on sports in Colorado. 

  • Only One Account Per Sportsbook

    While some users may think this is a rule implemented by sports betting operators, it’s actually state law. It is perfectly acceptable to have accounts at several different online sportsbooks, but you can only have one account at each of these. If you are found to have multiple accounts at one sportsbook, you are breaking the law and the accounts will be closed.

  • All Colorado Sports Bettors Must Be 21 Or Older

    This is a fairly well-known rule, but what some don’t realize is that you also need to prove your age and identity. This can be done by providing your Social Security number or a valid form of identification. Not only does this ensure that you are the legal age for sports betting, but also that you are not opening multiple accounts at a single sportsbook.

  • Required User Data

    Alongside proof of age, sportsbooks must have the residential address, phone number, full name, e-mail address, social security number and date of birth of all customers. These are all legal requirements.

  • Responsible Gaming

    All users must be warned of the dangers of problem gambling and encouraged to gamble responsibly. This means online sportsbooks must provide detailed information of how to place limits on gambling and how to access those tools.

  • Account Funding

    Users can fund their account by using a credit or debit card, online transfer, promotional credits, cash at a participating retail partner or any of several other methods approved by the regulator. They cannot transfer funds from their account to another user’s account.

  • Users Must Be Located In Colorado

    All Colorado bettors must be physically located in the state if they wish to place a wager at a Colorado sportsbook. Even if they are a resident of the state and have a valid account but are across state lines, they cannot place sports bets at a Colorado sportsbook. Of course, if the state where they are has legal sports betting, they can be there.

  • Proxy Betting

    Colorado sportsbook staff cannot place wagers on behalf of users at either retail sportsbooks or through mobile sports betting apps.

  • Taxes Must Be Paid On All Bets

    All sports bets are subject to state and federal taxes. The Colorado income tax rate is 4.4%. The federal tax rate is 24%.

Colorado Sports Betting Oversight

Regulatory Bodies Overseeing Colorado Sports Betting

All gaming in Colorado is overseen by the Colorado Limited Gaming Control Commission. This is a five-member regulatory body (appointed by the Governor) that meets on a regular basis and is seen as the final authority on all things related to licensed gaming in the state. This includes the adoption of rules and regulations, the final approval of license holders, and any alterations to gaming tax rates. 

The Colorado Division of Gaming operates under the supervision of the Department of Revenue and works alongside the CLGCC. It is responsible for implementation of the commission’s decisions and the general day-to-day running of the gaming industry. 

Role Of The Colorado Division Of Gaming In Sports Betting

The Colorado Division of Gaming is seen as the chief regulator of the state’s sports betting operations. As noted earlier, the Division works closely with the CLGCC to oversee sports betting and is mainly responsible for the following: 

  • Licensing
  • Regulatory compliance
  • Monitoring and auditing
  • Consumer protection
  • Technical standards
  • Problem gambling support

Colorado sports betting law has approved the following online sportsbooks, many of which have perks that I think separate them from the rest.

Online, Retail Sports Betting Opportunities

Exploring Online And Retail Sportsbooks In Colorado

As we mentioned earlier, sportsbook options in Colorado are nothing short of incredible. But it's important to note that while both the retail sportsbook and online betting are similar, there are some differences in terms of bonus bets and promotions.

The app has a simple and extremely user-friendly interface, and offers a wide range of sports to bet on. It offers a great bet $5, get $200 in bonus bets + $150 in No Sweat Bets but falls a little short on the regular promotions for existing users. Even so, its competitive odds and range of sports make it a shoo-in for the best sports betting app in Colorado. 

Caesars Sportsbook

One of the biggest names in casino gaming, it’s no real surprise that Caesars sportsbook has started to excel in the Colorado sports betting market. While its platform may not be quite as slick as DraftKings' excellent app, the Caesars rewards program is second to none. You even can redeem your loyalty points at brick-and-mortar Caesars casinos. Add to that the incomparable $1,000 First Bet on Caesars and this comes in a very close second to DraftKings. 


The range of sports gambling markets available at BetMGM Colorado is one of the best in the industry. The online sportsbook has a wonderfully intuitive bet slip that makes creating parlays and figuring out potential winnings a dream. The edit my bet feature is also a pretty nifty one that allows you to change parts of your bet even after you have placed it. While the interface may not be as easy to manage for new users as the DraftKings' interface, the first bet offer up to $1,500 makes the slight learning curve worth it. 

New users also have the choice of a Bet $10, Get $200 in bonus bets offer if they prefer that over the first bet offer. Be aware, however, you can only claim one of the welcome bonuses and they cannot be combined. Both are great offers and the one you choose will depend on your wagering style. The bet-and-get offer is perfect for bettors of any level while the first bet offer may be better suited for more experienced bettors with a larger bankroll.

Yes, all winnings from any form of gambling must be declared as an income in Colorado. This means winnings from sports betting are subject to the standard income tax rate of 4.4%. This is payable on all sports betting winnings no matter how big or small. It’s also worth noting that this is only the state tax rate. Federal income taxes must also be paid on any winnings at a rate of 24%

If, for example, you won $1,000 on the Denver Broncos making the playoffs, you’d have to pay $44 in state taxes and $240 in federal taxes. 

Colorado sportsbook operators are obliged to report gambling winnings over a certain threshold. At the time of writing, this threshold is $600 for sports betting. Once you hit that threshold, the operator must issue a W-2 G that you must fill out. The W-2 G form is held for the IRS and your yearly tax return will be cross-referenced against any W-2 Gs held by sportsbooks to ensure that you have declared all your winnings as income and have paid the required taxes.

Tips For Successful Sports Betting In Colorado

One of the best tips you’ll ever get for successful sports wagering in Colorado is to always shop around. Now, you may think that this means shopping around for the best welcome bonus and, while this is a good tactic, it’s not all you should be doing. We actually recommend that bettors take full advantage of multiple welcome bonuses and open accounts with several sportsbook platforms.

The idea here is not just to get the most value for money through those welcome bonuses but to also give yourself options. For example, if you decide to back the Denver Nuggets to retain their NBA Championship, you may find that odds can vary a bit from one sportsbook to the next. You may also find that the likes of PointsBet (the Nuggets official sports gambling partner) may have some special deals on this type of wager.
