Gambling tax in Colorado
Colorado is the straightforward case: a flat 4.4% on gambling winnings, and losses reduce the state figure whenever you itemize federally. There are no county add-ons, no venue restrictions and no separate state rules to track. The Colorado line moves in lockstep with the federal deduction decision.

Itemizing is the only lever
Because Colorado follows the federal treatment, the itemize toggle does all the work. Leave it off and Colorado taxes gross winnings at 4.4%. Turn it on and Colorado taxes winnings minus the losses the federal 90% cap allows. For a high-turnover bettor, the standard versus itemized comparison the calculator prints below the inputs is a Colorado decision as much as a federal one, and the two move together rather than against each other. That is not true in Illinois, Ohio or Indiana, where the state figure ignores the federal choice entirely.
Colorado gambling tax FAQ
Does Colorado tax sportsbook and casino winnings differently?
No. The 4.4% rate applies to gambling income whatever its source, and the loss deduction carries no venue restriction of the kind Michigan and Massachusetts apply.
Is there a local income tax on winnings in Colorado?
Not in this calculator. Colorado is modelled as a single flat state rate with no county or city layer, unlike Maryland, Indiana and New York.
Betting outside Colorado?
