Fuel Taxes

Overview

Every time you put fuel in your vehicle, motorcycle, truck or airplane, the price per gallon of fuel includes fuel taxes. Those taxes are collected and remitted to the state of Montana. The monies are used to support and maintain a safe transportation system across Montana.

ATTENTION: Diesel Fuel Users
Please be advised that the National and State Covid-19 Emergency Declaration does not include the ability to use non-taxed diesel fuel (dyed diesel) in motor vehicles traveling on public roads and highways. Using dyed diesel on Montana roadways could be result in a penalty not to exceed $1,000.00 for a first offense and $5,000.00 for a second offense.
