International Fuel Tax Agreement or IFTA is required for vehicles over 26,000 lb crossing state lines – interstate commerce. IFTA License must be kept in each vehicle and decals displayed on the truck. The process might be quite time-consuming, but we make sure we obtain supporting documents from you to process IFTA application smoothly. In each state, there are its own requirements, so we have to make sure we follow all steps properly. You will need to keep track of the mileage traveled in each state and the fuel purchased in each state. You will receive an IFTA quarterly report from your state each quarter to determine if you owe fuel taxes or if you get a fuel tax refund.
