International Fuel Tax Agreement (IFTA)

The International Fuel Tax Agreement (IFTA) is an agreement among states and Canadian provinces to simplify the reporting of fuel use taxes by interstate motor carriers. In California, IFTA is administered by the Motor Carrier Section of the Board of Equalization.

If you operate a diesel qualified motor vehicle between California and Mexico only, see our information on the Interstate User Diesel Fuel Tax (DI) License.
