International Fuel Tax Agreement (IFTA) decals are valid from their issue date until December 31 of the same calendar year.
You can display your new IFTA decal one month early. If you display your decal early, you must have a current IFTA Carrier Licence and a current set of decals properly placed on your vehicle.
Instructions for the placement of your IFTA decal are on the back of each set of decals.
