State Gas Tax Adjustments Have Limited Impacts on Pump Prices, ARTBA Analysis Shows

The association examined 177 changes in state gasoline tax rates in 34 states between 2013 and 2021 and found that on average, just 18 percent of an increase or decrease was passed on to motorists in the retail price of gasoline in the two weeks after a change took effect.

The results come as 24 states have either enacted or are considering a temporary suspension of their gas taxes or other transportation-related user fees. Legislation has also been introduced in the U.S. Senate and House of Representatives to suspend the federal gas tax for the rest of the year.
