International Fuel Tax Agreement (IFTA)

Qualifying commercial motor vehicles traveling in more than one state or province of Canada file a consolidated report of motor fuels taxes (e.g., Gasoline, Diesel Fuel, Liquefied Gas, Compressed Natural Gas and Liquefied Natural Gas Taxes) under the International Fuel Tax Agreement (IFTA). IFTA is not a separate tax or fee.

IFTA Reporting

IFTA fuel tax reports can be filed electronically using WebFile or EDI software, or on paper using Form 56-101, International Fuel Tax Agreement (IFTA) Fuel Tax Report (PDF), and Form 56-102, IFTA Fuel Tax Report Supplement (PDF).

Rates

Each member jurisdiction sets its own tax rate. Interstate carriers based in Texas report fuel tax paid in all member jurisdictions. Tax rates for current and prior periods can be found at IFTA Inc.

Interest Rates

The current annual interest rate is 6% and the monthly interest rate is 0.5% (0.005). For more information about penalties, interest and refunds, read our FAQs.

Due Date

Quarterly on the last day of the month following the end of the calendar quarter. If the due date is a Saturday, Sunday or a legal holiday, the next business day is considered the due date.
