Sports Betting in Colorado

Back in 1949, any Colorado resident looking to place a legal wager could do so on live Horse and Greyhound races only. The introduction of bingo in the late ’50s, and the Colorado Lottery in the early ’80s, was as much legal betting excitement Colorado visitors and residents could enjoy. 

1990 saw the passing of the Colorado Limited Gaming Initiative (soon became law), which legalized some gaming options in the mountain towns of Black Hawk, Central City, and Cripple Creek. Maximum bets were limited to $5, but casinos could stay open 24/7.

By 2014, gaming limits had increased to $100 per bet, and greyhound racing was made illegal under Colorado law. With daily fantasy sports beginning to catch on in 2016, accompanied by the considerable sporting fanbase of Colorado-based major league teams, the next big market to come under review was, inevitably, the Colorado sports betting market.


Betting Tax in Colorado - all for a great cause 

Taxes associated with Colorado sports betting are similar to those of most states, with all winning wagers subject to federal and state income taxes.

Colorado state income tax is set at a flat rate of 4.63% regardless of your annual profits. Although the taxation of winnings may be seen as a negative, Colorado has managed to ensure the money received is put to positive use, supporting many great local causes. Those of you residing in CO will see your tax contributions provide more resources to community colleges, promote travel and tourism, support innovative businesses, and preserve the Centennial State’s rich history and heritage.

Regardless of whether your Colorado sports betting profits came from online betting platforms or at a retail sportsbook, all winnings are considered taxable income and must be reported to the IRS.

Your winnings must be recorded as other income on the 1040 form, and If your winnings exceed $600, you will need to pay a federal tax of 24%. It is important to note that the $600 tag relates to non-monetary winnings too. Any holidays, cars, memorabilia, etc. that may have been won during the year will need to be itemized according to their monetary value and will incur, where necessary, the 24% federal tax fee.

Betting Restrictions in Colorado - Zero limit on Pro sports 

Casino-style gambling has been legal in the state since 1991. With slots, table games, bingo, poker, and much more available to retail users, it would be safe to suggest Colorado gambling options do not leave visitors or residents wanting.

Whilst there are no limitations when betting on professional sports, Colorado sports betting law does prohibit line, in-play, and prop bets on NCAA markets.

Colorado is one of the regions in the United States of America that allows individuals to bet on different sports. The state enacted this law in 2019, with the taxation of sports betting sites being slightly higher. But this didn't stop operators from offering sports betting services to gamblers in the state. 

In fact, Colorado is among the few regions in America with a wide range of sportsbooks that will see you spoilt for choice. Some of the top bookmakers operating in Colorado include BetMGM and FanDuel. The state also allows gamblers to place bets on BetUK, a sportsbook with cashout, a bet builder feature, and mobile apps. Those who want to live stream select matches can sign up on William Hill or BetRivers. The operators are regulated by the Colorado Limited Gaming Control Commission (CLGCC) to ensure fair services.

Are Betting Losses in Colorado Tax Deductible?

Earlier in our Colorado sports betting review, we discussed betting tax in the Centennial State and how your money is used to better education, tourism, and the history of CO. In this section, we at Oddspedia look to explain how you can claim your sports betting losses back and the importance of record keeping. 

Your federal tax return requires you to adequately document your Colorado sports betting activity, following a strict set of criteria. Unfortunately, keeping hold of losing tickets is not enough evidence, and you will need to provide a log of all winning and losing wagers throughout the year.

Some reputable online sportsbooks will provide this information for you, allowing you to download your data when the time comes. However, for those of you making use of retail sportsbooks, you will need to take it upon yourself to keep a log of your betting history.

To ensure you have included all relevant details, ensure you have entered the date and type of gambling activity, as well as the name address of the gambling establishment. Next, include the names of any other persons present at the said establishment and, finally, the amount won or lost.

Your losses can then be written off as a miscellaneous itemized deduction, but it is worth noting that any losses exceeding your winnings will not be factored into your tax contributions and cannot be carried over into the next financial year. 

In simple terms, if you win $500 but lose $600, you will only be entitled to claim back on $500.


It is safe to say the legal Colorado sports betting scene is thriving. Online sportsbooks are making use of Colorado’s minimal limitations and restrictions, creating a hub of great platforms for Colorado residents and visitors to choose from.

Before selecting your new retail or online sportsbook, it is important to understand that different operators will provide different markets, promotions, bonuses, and features. To ensure you find the best sportsbook Colorado has to offer and a sportsbook tailored to your needs, we suggest doing your own due diligence before signing yourself up – checking T’s & C’s, online reviews, payment methods, and sign-up bonuses.
