Where Gilpin County casino tax money goes, and why it matters locally

Colorado's casino tax in Black Hawk and Central City is split by formula among the state, historic preservation, the gaming towns, and Gilpin County.

Published June 10, 2026 - Last verified June 11, 2026

Casinos in Black Hawk and Central City do more than draw visitors; they fund a large machine of public money, and some of it flows back to Gilpin County. Colorado taxes casinos on their adjusted gross proceeds, which is roughly what they keep after paying out winnings. The Limited Gaming Control Commission sets the tax rates, and state law caps how high they can go.

After expenses, the money is split by a formula written into law. A large share goes to the state, a sizable portion goes to the State Historical Fund for preservation work, and a slice goes to the gaming towns of Black Hawk, Central City, and Cripple Creek based on how much tax each generates. Under a later voter measure, additional gaming money is directed mostly to community colleges, with smaller shares going to the gaming counties, including Gilpin, and the gaming towns.

For residents, this explains a lot: why historic buildings keep getting restored, why two small towns can afford big public projects, and why county finances here are tied to an industry most counties do not have.

The exact rates and percentages can change, so do not quote a number from memory. For the current structure, see the Colorado General Assembly gaming-tax overview and the Department of Revenue’s Limited Gaming Fund page.
