Colorado Online Sportsbetting: Legal Aspects

State regulators legalized Colorado online betting sites on May 1, 2020. Coloradans now have no need to use unreputable and unlicensed offshore sportsbooks. By using a legal Colorado sports betting app or website, you know your money is secure.

When evaluating each Colorado online bookmaker, we focused on some important points. Our number one priority is safety and security for Colorado bettors. All our recommended Colorado betting sites use the highest level of encryption and are fully licensed and regulated.

It might be tempting, but it isn’t worth the risk to use an illegal sportsbook. Stick to licensed and trustworthy Colorado bookmakers. By doing that, you know you are gambling within the law and in a secure environment.

Law and Licenses

Online gamblers should always use legal betting sites in Colorado. Betting at offshore sportsbooks is breaking state law. It is also a very risky proposition, as you have no way of knowing if your funds are safe and if you will get paid out on your winning bets.

The Colorado Division of Gaming licenses all online sportsbooks and gambling venues in the state. The board thoroughly examines and tests all Colorado betting sites before they can receive a license to operate.

Online sportsbooks in Colorado must partner with one of the state’s 33 casinos to receive an operating license. All betting sites must pass a number of regulatory checks to meet the licensing requirements of the Colorado Division of Gaming.

Online sports betting in Colorado isn’t exclusive to state residents. If you have a valid Social Security Number and are located within state lines, you can sign up and bet. Likewise, Coloradans can also gamble online in other states, such as Nevada.

Online Gambling Taxes in Colorado

Winnings from successful sports wagers in Colorado are subject to federal and state income taxes. For a big win, you may have a W-2G form sent to you automatically. Colorado has a flat state income tax of 4.63% and all gambling wins must be reported on your annual tax returns.

Operators also must pay their share of taxes to the state. Gambling sites are taxed at a flat rate of 10% of gross profits. This is relatively low compared to other states with legal online gaming. A large proportion of the taxes collected go towards funding the Colorado Water Plan.

Data Security and Encryption

All licensed Colorado betting sites should use a secure socket layer connection. This ensures all information sent between you and the gambling site is encrypted. Look for a padlock symbol to the left of the website address. Each Colorado sports betting app should also use encryption to protect your information.

It is up to you as an individual to protect yourself when you gamble online. When you play on Colorado betting sites, online security steps should be followed. Use strong passwords on your computer or mobile device and install updated anti-virus software. Only download gambling apps from their official sources.

Legal Gambling Age in Colorado

To gamble with an online bookmaker, Colorado law dictates that you must be over the age of 21. This age limit is strictly enforced, and minors should not seek to circumvent this rule.

Through searching online, you might find bookies that claim you can bet legally in Colorado from the age of 18. But be wary, as these offshore sportsbooks are illegal and should not be trusted with your hard-earned money.

Responsible Gambling in Colorado

Problem gambling is taken seriously in Colorado. If you have difficulties arising from using any of the best Colorado betting sites, then the Problem Gambling Coalition of Colorado can assist you. The PGCC provides a 24-hour confidential helpline (1-800-522-4700) for anyone affected by the issue.

On the PGCC website, you can self-exclude from online gaming in Colorado. You can choose how long you would like to exclude yourself, with a minimum period of three years. The National Council on Problem Gambling and Gamblers Anonymous are two national organizations that can also help.

Certificates

For a Colorado bookmaker, online security is a crucial topic. A Colorado betting site can prove it is trustworthy with a certificate. Our list below shows the most important certificates that should be displayed by an online sportsbook in Colorado.

  • DigiCert – Security
  • Problem Gambling Coalition of Colorado – Responsible Gaming
  • Cloudflare – Security
  • National Council on Problem Gambling – Responsible Gambling

Look out for these certificates before you deposit your money. If a website or app displays the logos of these certificates, then you know they value your safety and security.

Colorado Betting Bonus & Offers

When considering the best betting sites Colorado has to offer, one of the most important factors is the welcome bonus. All our selected sportsbooks have great introductory offers to get Coloradan bettors started.

Remember to check the bonus terms and conditions before depositing. Each offer has individual requirements to satisfy before it can be completed. There might be playthrough stipulations or a minimum betting odds level to adhere to. Here are the welcome offers from Colorado’s top betting sites.

Remember though, don’t focus solely on the bonus at the expense of everything else. There are plenty of other factors to consider when getting into Colorado online sports betting. Read on as we take a look at other topics – such as payouts, odds, payment methods and mobile apps.

Average Payout, Odds, and Lines at Colorado Betting Sites

When gambling at the best online Colorado betting sites – you should always strongly contemplate their payout rates. Fair payout rates should be an important consideration when signing up to a new sportsbook.

Return to player (or RTP) is the percentage payout a bettor receives after the commission taken by the bookmaker. A sharp gambler always tries to maximize their potential payouts and minimize the vigorish that they pay to a sportsbook.

These are the average payout rates from our recommended Colorado betting sites. Hold these figures in mind but remember that rates vary from sport to sport. Larger payout rates mean you get more value on your bets, so don’t forget this.

Live Betting sites in Colorado

Colorado betting sites allow live betting on sports during a game. It is an exciting and dynamic way to gamble and a great way to add to your enjoyment of watching live sports.

Be aware that odds can change quickly in live betting, especially in a close sporting contest. Make sure you have up-to-date information before you bet on a live game, so you don’t get caught out if the odds alter. Here is our best Colorado live betting bonus.

The History of Gambling in Colorado

Despite liberal attitudes to subjects such as marijuana use and same-sex marriage, the Centennial State has been slow to embrace gambling. Horse racing began in Colorado in the 1940s and the state lottery commenced in 1982. Three Rocky Mountain casinos opened in 1991.

In 2005 the state of Colorado ruled online gaming illegal. When the Unlawful Internet Gaming Enforcement Act (UIGEA) was passed the following year – online sports betting in Colorado seemed like a long way off.

The Road to Legal Sports Betting in Colorado
  • Horse Racing Begins The Colorado General Assembly approves pari-mutuel horse racing in the state and the Colorado Racing Commission is created. Just one track remains in Colorado today.
  • State Lottery Created The Senate passes bill SB-82-119 to create the state lottery in Colorado. The first scratch-off is sold in January 1983 and the Colorado Lottery holds its first draw in April 1983.
  • Casino Gambling Approved Three casinos located in historic Rocky Mountain mining communities are allowed. Casinos open in Black Hawk, Central City, and Cripple Creek
  • Online Gaming Ruled Illegal The state of Colorado rules against the authorization of online gaming. This pre-empts the Unlawful Internet Gambling Enforcement Act (UIGEA) which follows a year later.
  • Professional and Amateur Sports Protection Act Repealed Following the US Supreme Court’s repeal of the Professional and Amateur Sports Protection Act, each state is now free to create its own regulations for legal sports betting.
  • Sports Betting Legalised in Colorado In spring the Colorado state legislature approves a sports betting bill. In November, Proposition DD passes after a contentious and closely fought vote. Betting on sports is finally legal in Colorado.
  • First Online Sportsbooks Open In May, Coloradans are able to bet online for the first time – signaling a new era of gambling in the Centennial State.

In 2019, the passing of Proposition DD finally legalized sports betting in Colorado. 2020 saw the launch of several new gambling websites in Colorado, as the first online sportsbooks opened. Residents and out-of-state visitors could finally legally bet on sports when inside Colorado state lines.

With what is regarded as a fair tax rate for operators and an industry that is already thriving – online sports betting looks set for a successful future in Colorado.
