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.

Changes to the IFTA Fuel Tax Report Forms

As of July 31, 2014, the Report Forms 56-101 and 56-102 have been revised. All paper reports must be filed using the updated forms or you can use the EDI software to file online.

Rates and Due Date

Tax Rates

Tax rates are set by each of the member jurisdictions. Interstate carriers based in Texas report fuel tax paid in all member jurisdictions.

Interest Rates

The current annual interest rate is 5% and the monthly interest rate is 0.417% (0.00417).

Quarterly Due Date

The IFTA report is due the last day of the month immediately following the close of the quarter being filed. If the due date is a Saturday, Sunday or legal holiday, the next business day is considered the due date.
