If a site isn't on the regulator's licensee register, ask the regulator before you play: an unlisted site is usually not licensed here (a register can lag behind a new licence). An unlicensed site is outside the regulator's supervision, so you cannot complain to the regulator about it.

Red flags: how to spot an unlicensed site

  • Check for the Official Colorado Division of Gaming Seal

    Licensed operators are required to display the seal of the Colorado Division of Gaming on their app and website. This seal indicates the site is regulated and legal within the state.

  • Verify the Operator on the Division of Gaming's List

    The Division of Gaming provides a spreadsheet of all licensed sports betting operators. Before depositing, cross-reference the brand name with this official list to ensure it is not an illegal offshore site.

  • Confirm Geolocation Technology is Active

    Legal sites must use geolocation software to confirm you are physically within Colorado's borders. If a site does not perform this check, it is not a legal, state-licensed operator.

  • Look for Prominently Displayed Responsible Gaming Tools

    All licensed sites must provide easy access to responsible gaming resources, including the 1-800-GAMBLER helpline and links to the state's self-exclusion program.

Common myths about gambling in Colorado

  • Myth
    My winnings aren't taxed in Colorado.
    Reality

    All gambling winnings are considered taxable income. They are subject to a flat 4.40% Colorado state income tax, in addition to federal taxes. For large wins (≥$5,000), operators are required to withhold 24% for federal taxes.

  • Myth
    It's legal to bet with any site that accepts Colorado players.
    Reality

    It is only legal to bet with operators licensed by the Colorado Division of Gaming. Offshore or unlicensed sites do not offer any consumer protections, and placing wagers with them may violate federal law.

  • Myth
    Tribal casinos can offer online sports betting across the whole state.
    Reality

    The state-tribal compacts under the Indian Gaming Regulatory Act (IGRA) allow the two tribal casinos to offer sports betting on their reservation lands, but they do not grant them the ability to offer statewide mobile betting off-reservation.
