Drivers in Mississippi, home to many of the poorest Americans, likely appreciate the low price of gasoline, which is taxed just 18.8 cents per gallon. The low gas tax in Mississippi means that the price of gas is less than $2 per gallon, as in only a few other states. Residents are close to major parts of the U.S. oil infrastructure, including the Mississippi River and the Gulf of Mexico.

Missouri levies 17.3 cents in taxes on a gallon of gasoline, the fifth lowest nationwide, versus a national average tax rate of nearly 30 cents per gallon. Partly as a result, the price of gas in the state is the lowest in the country, at just $1.74 per gallon. Also helping to keep costs down, Missouri is a transportation hub for oil, thanks to shipments along the Missouri and Mississippi rivers.

The low price of gasoline in New Mexico is due in large part to the state fuel tax of less than 19 cents on the gallon — the seventh lowest nationwide. The state was among the top crude oil producers in the nation in 2013, which may have also contributed to the cheap fuel available in the state.

Drivers in Delaware pay an additional 23 cents per gallon in state fuel taxes. While this is one of the lower tax rates in the nation, the price of fuel was on the higher, at $2.24 per gallon. Unlike many other states, Delaware does not produce any of its own fuel. The state imports most of its oil via pipeline from outside sources.

According to the EIA, Louisiana consumed more energy per capita than all but two other states in 2012, due in large part to industrial activity. The state is also a top refiner of oil — only Texas had more refineries as of the beginning of last year. High output and high consumption among both residents and businesses likely contributed to the state’s exceptionally low gas prices.
