About Gas Prices in Mississippi
The U.S. Energy Information Administration (EIA) surveys fuel retailers weekly but doesn't publish a separate price for Mississippi, so the price shown is the EIA's Gulf Coast regional average for regular unleaded gasoline. Prices at individual stations in Mississippi may be higher or lower depending on location, brand, and local competition.
Several factors influence Mississippi'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 Mississippi price affects your commute, road trip, or monthly driving budget.
Mississippi Fuel Taxes: ≈21¢/gal
Mississippi has one of the lowest state gas taxes in the nation. Mississippi's state gas tax is about 21 cents per gallon, one of the lowest in the country and well under 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, so verify current rates with the state's revenue or transportation department.
How Mississippi Gets Its Gasoline
Mississippi is home to Chevron's Pascagoula refinery, one of the largest in the United States, sitting right on the Gulf Coast. That massive local refining capacity, combined with the state's low fuel tax, is a major reason Mississippi is consistently one of the cheapest states in the country for gasoline.
Where Gas Is Cheapest and Most Expensive in Mississippi
The Gulf Coast, closest to the Pascagoula refinery, generally sees the lowest prices in the state. Prices rise gradually moving north and inland toward the Delta and the Tennessee border, reflecting the added trucking distance from the coast.
