International Fuel Tax Agreement -
What It Means for a Connecticut Motor Carrier

PURPOSE: On January 1, 1996, Connecticut will join the International Fuel Tax Agreement (IFTA) for the purpose of collecting and distributing fuel use taxes for Connecticut motor carriers. IFTA is an agreement entered into by jurisdictions (American states and Canadian provinces) under which motor carriers license and report their mileage and fuel consumption to their base jurisdiction.


Yes, if you operate a qualified motor vehicle that travels in two or more IFTA jurisdictions, you must be licensed under IFTA.

WHAT IS A QUALIFIED MOTOR VEHICLE? A qualified motor vehicle is any motor vehicle that is designed to transport persons or property and that has:

  • two axles and a gross vehicle weight or registered gross vehicle weight over 26,000 pounds; or
  • three or more axles regardless of weight; or
  • when used in combination, a combined gross vehicle weight over 26,000 pounds.

HOW DO I DETERMINE IF CONNECTICUT IS MY BASE JURISDICTION? Connecticut is your base jurisdiction if your vehicles are registered with the Connecticut Department of Motor Vehicles and:

  • your operational control and records of qualified motor vehicles are maintained or can be made available in Connecticut; and
  • some miles are accrued within Connecticut by qualified motor vehicles in the fleet.

HOW WILL I REGISTER FOR MY NEW LICENSE? If you are required to be licensed under IFTA and Connecticut is your base jurisdiction, complete CT-IFTA-1, Application For International Fuel Tax Agreement - Connecticut Carrier, and mail, with a check or money order payable to DRS, to:

PO BOX 2937
HARTFORD, CT 06104-2937

Be sure to identify the jurisdictions in which you operate or anticipate operating by marking the list of jurisdictions provided in CT-IFTA-1, Line 3.

WHAT WILL I RECEIVE ONCE MY APPLICATION IS PROCESSED? You will receive two IFTA decals for each licensed vehicle. Decals must be affixed to the lower rear exterior on each side of the cab.

In addition, you will receive a license that must be photocopied and kept in each licensed vehicle.

All Connecticut based licensed IFTA carriers will receive new tax returns beginning in the first quarter of 1996.

HOW DOES THIS AFFECT MY FUEL TAX REPORTING? IFTA affects your fuel tax reporting by eliminating paperwork. Your fuel tax for all IFTA jurisdictions will be reported quarterly through the DRS (your base jurisdiction) using one tax return. Miles traveled, gallons purchased and fuel taxes paid for all jurisdictions are reported each quarter on that one return. The single return simplifies your reporting requirement by allowing you to net your fuel tax liabilities and credits for each IFTA jurisdiction, then net the fuel tax liabilities and credits for all IFTA jurisdictions.

WHAT JURISDICTIONS ARE PARTICIPATING IN THE IFTA PROGRAM? All of the 48 contiguous states (except Maine, New Hampshire and Vermont) will belong to IFTA by September 30, 1996. Several Canadian provinces have agreed to join. Maine, New Hampshire and Vermont remain members of the Regional Fuel Tax Agreement and are not members of IFTA.

For information regarding a jurisdiction's membership status, call the Department of Revenue Services at 860-541-3222.

WHAT DO I DO IF I TRAVEL IN ONE OF THE ABOVE JURISDICTIONS THAT IS NOT PART OF IFTA? You will still have to maintain your own account with each jurisdiction that does not participate in the IFTA. If you travel in Maine, New Hampshire or Vermont, you will continue to follow the requirements of the Regional Fuel Tax Agreement.

HOW CAN I LEARN MORE ABOUT THIS PROGRAM? The Department of Revenue Services has scheduled free seminars to introduce the International Fuel Tax Agreement.
