<P> The table below includes state and local taxes and fees . The American Petroleum Institute uses a weighted average of local taxes by population of each municipality to come up with an average tax for the entire state . Similarly, the national average is weighted by volume of fuel sold in each state . Because many of the states with the highest taxes also have higher populations, more states have below average taxes than above average taxes . </P> <P> Most states exempt gasoline from general sales taxes . However, several states do collect full or partial sales tax in addition to the excise tax .
