Gasoline taxes are state-imposed fees on every gallon of fuel purchased. They’re primarily used to fund road repairs, public transportation, and other infrastructure projects. While the federal gas tax remains fixed at 18.4 cents per gallon, states add their own on top and some go much higher than others.
