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. The purpose of IFTA is to establish and maintain the concept of one fuel use license for carriers operating qualified motor vehicles interstate. An IFTA license allows a taxpayer to file one tax report that covers all member jurisdictions. The base jurisdictions for each licensee will administer the agreement on behalf of all fellow member jurisdictions.

If you operate a qualified diesel motor vehicle between California and Mexico only, you should register for a California Interstate User Diesel Fuel Tax (DI) License.
