s the KYU number the same as IFTA?

NO!!! KRS 138.660. establishes the fuel tax, surtax, and Kentucky Weight Distance Tax (KYU) You cannot pay for KYU on your IFTA tax form. IFTA is a fuel tax based on the fuel consumed by a vehicle within a certain IFTA jurisdiction.

IFTA taxable vehicles start at over 26,000 pounds or has 3 or more axles regardless of weight.

KYU however, is a highway usage tax that is based purely on KY mileage. KYU taxable vehicles start at over 59,999 pounds. If your vehicle is over 59,999 pounds, you will need to pay both.

I am leased to another motor carrier for authority. What should I display on my vehicle?

In the case of a lease please display the name, US DOT number, and MC number of the carrier that you are leased to. If your vehicle is subject to the KYU tax and the company with authority is not providing the KYU tax license, then you must obtain either a temporary permit for the KYU tax, or provide your own KYU tax license linked to your own US DOT number. Kentucky recommends that you display your personal KYU number. However, you are not required by law to display the KYU number. To avoid confusion and delay, it is best if the lease agreement is very clear about which company is paying for which credential.
