About Gas Prices in Arizona
Gas prices in Arizona 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 Arizona may be higher or lower depending on location, brand, and local competition.
Several factors influence Arizona'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 Arizona price affects your commute, road trip, or monthly driving budget.
Arizona Fuel Taxes: 18¢/gal
Arizona has one of the lowest state gas taxes in the nation. Arizona's state gas tax is just 18 cents per gallon — among the lowest in the country and unchanged since the early 1990s. Despite that, Arizona pump prices often run near or above the national average, which surprises many drivers.
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 Arizona Gets Its Gasoline
The reason is supply: Arizona has no refineries and gets all of its gasoline by pipeline from two directions — California refineries feeding Phoenix from the west, and Texas/New Mexico refineries feeding the state from the east. When California refineries have problems, Phoenix feels it directly. Phoenix also requires its own Cleaner Burning Gasoline blend in summer, which fewer refineries produce.
Where Gas Is Cheapest and Most Expensive in Arizona
Tucson, which can use conventional gasoline and draws more supply from the El Paso side, is usually the cheapest big city in Arizona — often 20–30 cents below Phoenix. Flagstaff and other northern areas pay a trucking premium.
