International Fuel Tax Agreement (IFTA)
IFTA is an agreement that provides for the consolidated reporting of motor fuels (i.e., Gasoline, Diesel Fuel, Liquefied Gas, Compressed Natural Gas, Liquefied Natural Gas) taxes for qualifying commercial motor vehicles traveling in more than one state or province of Canada. IFTA is not a separate tax or fee.
