Colorado Gov. Polis Proposes Boosting Casino Taxes

Colorado Governor Jared Polis has proposed raising the effective tax rate on land-based casinos from 16.1% to 23%. The plan also introduces a 35% top marginal rate for the four highest-earning properties to fund childcare and preschool programmes. For players, increased casino taxes typically lead to reduced promotional budgets, tighter loyalty comps, and a need to carefully evaluate where you spend your money.

What is Governor Polis proposing for Colorado casino taxes?

He is proposing an increase in the effective casino tax rate from 16.1% to 23%. This adjustment would bring the state closer to the 26% national average. His budget proposal also sets a 35% top marginal rate for the four highest-earning properties. State officials project this gaming tax change will generate $80.2 million annually. Combined with proposed alcohol and tobacco tax hikes, the total reaches nearly $129 million.

That's a significant jump for operators. The state currently uses a tiered structure capping rates between 20% and 27.5% for venues earning $20 million to $100 million in annual gross gaming revenue. Four properties sit at the top of this ladder. Recent figures support this concentration. Statewide casinos generated $97.5 million in gaming revenue during September 2026. Black Hawk venues alone captured $73.9 million of that total.

Why should casino players care about a tax rise in Black Hawk?

Players should care about a Black Hawk tax rise because operators don't absorb these costs willingly. That financial pressure almost always shifts directly to you. When a venue's effective tax rate jumps from 16.1% to 23%, promotional budgets shrink rapidly. Loyalty comps dry up. Table and slot returns often become less generous. In our checks of jurisdictional tax hikes, it's the exact pattern we see in our casino guides whenever a local area tightens its rules.

This area remains one of the fastest-growing casino markets in the United States. More than a dozen venues operate in this single location. Major operators like Bally's, Caesars Entertainment, Monarch Casino & Resort, and Penn Entertainment run properties there. These specific brands face the most exposure to the proposed 35% top tax bracket.

You'll need to know the practical reality here. Land-based players in Colorado should expect heavy lobbying from operators before any law passes. The Taxpayer Bill of Rights (TABOR) requires voters to explicitly approve new tax increases. Consequently, this measure heads to the November 2027 statewide ballot. That won't hit your bankroll this year.

What does Colorado's betting history tell us about the odds?

Historical voting in Colorado shows voters will back gambling revenue measures, but they routinely reject straight rate hikes. The public overwhelmingly passed Proposition JJ in November 2024. That measure let the state retain sports betting tax revenue exceeding the original $29 million annual cap instead of refunding operators. Retaining surplus revenue differs vastly from approving a direct tax increase under TABOR rules.

We're tracking this closely for the sportsbook and prediction-market crowd. A state seeking education and childcare funding has a clear template for extracting more from gambling. Sports betting often becomes the easiest target. You must verify your online book holds a proper licence before you deposit. Check that withdrawal terms are clean. Our best online casinos page details what a fair operator requires. The responsible gambling tools hub explains how to set deposit limits that survive any tax-driven promotional squeeze.

How should players prepare for the 2027 ballot?

Players should treat this as a 2027 ballot fight rather than an immediate 2026 bankroll problem. You'll be fine playing in Colorado as normal right now. Watch for operators trimming comps and bonuses if the measure gains political traction. Treat any tax hike promotional offer as pure marketing rather than genuine value. Compare licensed operators on our casino bonuses page before you commit your funds. You can't dodge costs by using unlicensed sites, and those players always lose.
