How long has it been since your state has raised its gas tax?

Every time a vehicle is filled with gas, a proportion of the cost helps pay for the roadways and bridges those cars, trucks, and semis wear down. Most government officials don’t want to bear the responsibility of raising the price at the pump, but many states are revising their gas tax policies so they can pay for their aging infrastructure. States are adjusting their rates because taxes in recent years haven’t brought in enough revenue to keep up with increased fuel efficiency, and rising costs of building and maintaining transportation infrastructure.

The federal gas tax stands at 18.4 cents a gallon, which supports the Federal Highway Administration and hasn’t been raised since 1993. States institute a flat-rate gas tax, a percentage on the price of wholesale fuel or a general sales tax on top of that, meaning the total amount paid includes the cost of gas plus federal and state taxes.

More than half of U.S. states have raised gas taxes since 2013, with some states increasing their gas tax rates annually according to inflation rates tied to the Consumer Price Index. However, Alaska hasn’t increased their state tax on fuel since the 1970s, and the last time Mississippi increased their gas tax was in the 1980s. Using data from the American Petroleum Institute and the Institute on Taxation and Economic Policy, Stacker compiled a list to show the last time each state raised their gas tax.

Years since last gasoline tax increase: 0

On June 27, Oklahoma increased its tax on motor fuel for the first time in more than 30 years. The new rate increased the tax from 3 cents to 19 cents per gallon. The state decided to raise the gas tax because general funds that were previously used to fund transportation are currently being used for teacher pay.

#50. Vermont

Years since last gasoline tax increase: 0.1

Vermont instituted a 5.9-cent restructuring on their gas tax in 2013, and a .42-cent increase went into effect on July 1. The state’s tax is linked to the price of gasoline, so the amount customers pay varies. However, the price on gas is a little confusing in this state, with motorists paying the federal tax, as well as a state tax and two assessments.

Maine’s gas tax has stayed the same since 2011, when the state voted to stop adjusting annually for inflation.

Years since last gasoline tax increase: 26.6

The Lone Star State’s 20-cent tax has stayed steady since 1991. According to a 2016 poll by the Texas A&M Transportation Institute, increasing the state gas tax by 5 cents or linking it to yearly inflation were the most supported ways to increase revenue for infrastructure.
