What is Arizona's gas tax?
Arizona's state gas tax is approximately 19¢ per gallon, one of the lowest in the United States. This is a combined state excise tax and in some states includes local levies. The federal gas tax adds an additional 18.4¢/gal on top of state taxes.
When is the cheapest time to buy gas in Arizona?
