The International Fuel Tax Agreement (IFTA) is a process by which motor fuel taxes are collected and distributed to the states in which interstate motor carriers operate.

If you operate any of the following vehicles or combinations in interstate commerce, you must obtain a fuel permit/IFTA:

  1. A single unit with two axles and a registered or actual weight exceeding 26,000 lbs., or
  2. A single unit with three or more axles, regardless of weight, or
  3. A combination vehicle with a registered or actual weight exceeding 26,000 lbs.

However, if your vehicle is a government vehicle, school bus, Kansas farm registered, or recreational vehicle, you are not required to obtain a fuel permit.
