Colorado Gas Taxes

Colorado drivers pay about 29¢ per gallon in state gasoline taxes (roughly 47.4¢ with the 18.4¢ federal tax) — 4.7¢ below the 33.7¢ average across the 50 states and D.C. (approx., as of 2025).

Why Colorado Prices Move

Rocky Mountain product markets are thinner than the Gulf Coast. When local refining falters, Colorado prices can jump even if the national average is calm. Winter blends and mountain logistics also matter.

Colorado Gas Prices — Frequently Asked Questions

What is the average gas price in Colorado?
The EIA publishes a weekly average retail price for regular gasoline, typically each Monday for the prior week. This page lists the current Colorado weekly average with its survey date and trend. It is a survey average, not a live pump price.
What is the gas tax in Colorado?
Colorado drivers pay about 29¢ per gallon in state gasoline taxes (roughly 47.4¢ with the 18.4¢ federal tax) — 4.7¢ below the 33.7¢ average across the 50 states and D.C. (approx., as of 2025).
Are these live pump prices in Colorado?
No. These are EIA weekly survey averages for Colorado, not real-time prices at individual gas stations. Check local stations or a pump-price app for the current street price.
Why is gas expensive (or cheap) in Colorado?
Colorado gas can run above the U.S. average when regional supply is tight. The state fuel tax is about 29¢/gal (approx., as of 2025) before federal tax — near the national average — so logistics and refining usually explain spikes more than tax alone.
