You will be issued a single IFTA license (cab card) for your fleet of vehicles. The license is valid from January 1 through December 31. Make photocopies of the original license and place a copy in each of your vehicles. Keep the original license in a safe place. Use the original to make additional copies when adding a vehicle to your fleet during the license year.

IFTA Identification Decals

Licensees are issued two vehicle identification decals for each qualified vehicle in their fleet. An identification decal must be placed on the lower rear exterior portion of each side of the vehicle’s cab. Failure to display the IFTA identification decals in the required locations or to carry a temporary permit may subject the vehicle operator to the purchase of a trip permit, the issuance of a citation or both.


First-time applicants for an IFTA license are not required to furnish a bond unless the applicant has a prior history of delinquency in reporting or payment of taxes to the State of Connecticut.

License holders must furnish a bond if they are delinquent in reporting or paying a tax liability for any two reporting periods during a 12-month period. A bond, if required, must be maintained for two calendar years and shall be equal to twice the average quarterly tax liability for the taxpayer.

Any IFTA licensee who is required to furnish a bond is required to maintain timely filings and payments for two calendar years before the bond requirement is waived.

The requirement for bond may be satisfied by a cash bond, a bond issued by a corporate surety or a certificate of deposit endorsed in favor of the State of Connecticut. The payee of the certificate shall receive any interest payable on it.
