Mississippi gas prices
Mississippi is consistently one of the cheapest states for gas in the entire country. Sometimes it's the cheapest. The reasons are straightforward: very low state gas taxes, direct proximity to Gulf Coast refineries, and a pipeline network that keeps supply flowing without long transportation hauls.
The state sits in the heart of PADD 3 refinery country. Fuel from Louisiana and Texas refineries reaches Mississippi stations quickly and cheaply. There's also a small refinery in Pascagoula that adds to local supply. Low cost of living and competitive retail markets keep station margins thin, which benefits drivers.
Price history
Is Mississippi really the cheapest state for gas?
It's almost always in the top 3 cheapest, and frequently number one. The combination of very low state taxes, proximity to Gulf Coast refineries, and a low cost of living that keeps station operating costs down all contribute.
How low are Mississippi's gas taxes?
Mississippi's state gas tax is among the lowest in the nation at around 18 cents per gallon. Compare that to California at 70 cents or Pennsylvania at 58 cents. That tax difference alone accounts for a huge chunk of the price gap.
Does Mississippi have any refineries?
Yes. The Chevron refinery in Pascagoula is a large facility that processes about 330,000 barrels per day. It's a major source of fuel for Mississippi and the broader Southeast, and its location in-state keeps local supply robust.
