1. South Carolina

24/7 Wall St.: States with the Cheapest Gas

Regular gas price per gallon: $3.50

Tax per gallon: 16.8 cents (4th lowest)

Number of operating refineries: 0

Nowhere is gas cheaper than in South Carolina, where gas is 28 cents per gallon cheaper than the national average, and three cents cheaper than the second-cheapest state, Mississippi. Contributing to low prices are some of the lowest gas taxes in the country; South Carolina charges an excise tax of just 16 cents per gallon and other fees and taxes of only 0.8 cents per gallon. On September 15, 2008, prices hit their historical peak in the state, at $4.12. In June, gas prices fell below $3 per gallon.

10. Virginia Regular gas price per gallon: $3.62

Tax per gallon: 20.1 cents (13th lowest)

Number of operating refineries: 0

In the second quarter of 2012, the relative cost of transportation in Virginia was among the country’s lowest. Low gas prices are likely one reason for this. Virginia is also one of the wealthiest states in the country, with a median household income of $61,882 as of last year. Currently, Virginia charges 20.1 cents per gallon in total taxes and fees — more than 10 cents per gallon below the national average and inline with other states where gas is inexpensive.

9. Georgia Regular gas price per gallon: $3.60

Tax per gallon: 28.6 cents (20th highest)

Number of operating refineries: 0

Georgia’s excise tax of 7.5 cents per gallon of gas is lower than any state except for Florida’s. But with 21.1 cents per gallon in other fees and taxes, Georgians actually pay more in gas taxes than residents of 30 other states. High taxes likely contributed to the state’s relatively higher transportation costs midyear — the most expensive among those states with the lowest gas prices. The good news for drivers, however, is that the price of gas has fallen by 24 cents per gallon over the past month, more than in any other state.

8. Arkansas Regular gas price per gallon: $3.60

Tax per gallon: 21.8 cents (16th lowest)

Number of operating refineries: 2

Arkansas has access to locally refined gasoline. It has two refineries of its own, and it borders Louisiana and Texas, the two largest oil refiners in the country as measured by barrels per day. Having numerous refineries nearby helps lower the price of gas for Arkansas drivers, who presently pay 18 cents less per gallon than the national average of $3.78 a gallon. Arkansas also charges just 0.3 cents in other taxes per gallon in excise taxes.

7. Missouri Regular gas price per gallon: $3.60

Tax per gallon: 17.3 cents (6th lowest)

Number of operating refineries: 0

Although one year ago Missouri had the cheapest gas in the U.S., in the past year the price of gas has risen by 45 cents per gallon — more than in any other state. Despite the absence of any in-state refineries, Missouri has some of the nation’s lowest gas taxes, allowing gas to be sold at comparatively low prices. Among the state’s metropolitan areas, St. Louis has the cheapest gas at just $3.49 per gallon.

6. Louisianna Regular gas price per gallon: $3.59

Tax per gallon: 20 cents (tied for 11th lowest)

Number of operating refineries: 18

Only Texas refines more oil into gasoline than Louisiana, which has 18 operating refineries processing nearly 3.2 million barrels per calendar day. The abundance of locally processed gas and the total absence of any state gas taxes aside from an excise tax make trips to the pump highly affordable. The state is also home to the Louisiana Offshore Oil Port, which, according to the EIA, is the nation’s only port for offloading deep draft oil tankers.

5. Texas Regular gas price per gallon: $3.55

Tax per gallon: 20 cents (tied for 11th lowest)

Number of operating refineries: 26

Texas is the nation’s largest oil refiner, processing almost 4.66 million barrels per day — more than a quarter of the nation’s output — in its 26 operating refineries. Like Louisiana, the state further helps keep gas prices low by not charging any state taxes aside from a 20-cent excise tax. Two of the largest public companies in the nation, Exxon Mobil Corp. (NYSE: XOM) and Phillips 66 (NYSE: PSX), are Texas-based oil companies.

4. Tennessee Regular gas price per gallon: $3.54

Tax per gallon: 21.4 cents (15th lowest)

Number of operating refineries: 1

As of the second quarter of this year, no state was cheaper to live in than Tennessee. One major reason for the state’s low relative cost of living was its low transportation costs, despite starting 2012 with four consecutive months of gas price increases. Although the state has just one refinery, the price of gas is 24 cents per gallon below the national average price. In the past month, gas prices in Tennessee have fallen by 12 cents a gallon, one of the largest decreases in the country.

3. Alabama Regular gas price per gallon: $3.54

Tax per gallon: 20.9 cents (14th lowest)

Number of operating refineries: 3

One year ago, gas cost $3.30 a gallon in the state, compared to an average of $3.42 nationwide. At that time, gas prices in 12 states were cheaper than in Alabama. Since then, the state’s prices have risen by only 24 cents per gallon compared to a national average increase of 36 cents per gallon, making gas in the state far cheaper relative to the rest of the United States. The state helps keep costs low for drivers by limiting gas taxes. The state’s excise tax of 16 cents a gallon is among the lowest in the county.

2. Mississippi Regular gas price per gallon: $3.53

Tax per gallon: 18.8 cents (7th lowest)

Number of operating refineries: 3

Last year, Mississippi had a median household income of just $36,919, making it the poorest state in the country by that measure. Although the state’s economy is suffering, there has only been a 25 cents per gallon increase in Mississippi’s gas prices over the past year, compared a rise of 36 cents nationally. The state currently charges just 18.8 cents in state taxes per gallon of gas, less than all but six states. Costs also were kept down by a close proximity to the nation’s largest oil refiners, Louisiana and Texas.
