About Gas Prices in Idaho
Gas prices in Idaho are reported daily by the U.S. Energy Information Administration (EIA) as part of their weekly survey of fuel retailers. The price shown is a statewide average for regular unleaded gasoline. Prices at individual stations in Idaho may be higher or lower depending on location, brand, and local competition.
Several factors influence Idaho's gas price: state fuel taxes, the distance from major refineries, pipeline and distribution infrastructure, and the required seasonal fuel blend. Use the calculator above to see exactly how today's Idaho price affects your commute, road trip, or monthly driving budget.
Idaho Fuel Taxes: ≈33¢/gal
Idaho has a state gas tax close to the national average. Idaho's state gas tax is about 33 cents per gallon, close to the roughly 33.5-cent national average.
Tax figures are approximate state-level taxes and fees per gallon of regular gasoline and exclude the 18.4¢/gal federal excise tax. Rates change — verify current rates with the state's revenue or transportation department.
How Idaho Gets Its Gasoline
Idaho has no oil refineries of its own. The state is supplied by pipeline from two directions: refineries around Salt Lake City, Utah to the south, and refineries in Montana and Washington to the north. Which direction a given part of Idaho draws fuel from depends on geography — the mountainous terrain splits the state's supply routes more than most.
Where Gas Is Cheapest and Most Expensive in Idaho
Boise and southern Idaho track Salt Lake City-area wholesale prices fairly closely, while the northern Panhandle, around Coeur d'Alene, tends to move with Spokane, Washington prices instead. Rural mountain communities away from the interstate corridors generally pay a premium for delivery.
