International Fuel Tax Agreement (IFTA)
This is not a separate tax or fee. This is an agreement that provides for the consolidated reporting of motor fuels (i.e., Gasoline, Diesel Fuel, Liquefied Gas) taxes for qualifying commercial motor vehicles traveling in more than one state or province of Canada.
Tax rate is set by each of the member jurisdictions. Interstate carriers based in Texas report fuel tax paid in all member jurisdictions.
Quarterly: last day of the month following the end of the calendar quarter.
