Frequently Asked Questions​​​​​​​​​​​​​​​​​​​​​​​​​

A KYU number is a tax license number issued for the Kentucky Weight Distance Tax. Under KRS 138.660(3), any carrier over 59,999 pounds traveling in Kentucky is subject to this tax.
All incoming applications are processed within 7 to 14 business days of the receipt of the application. When your application is fully processed, you will receive by mail a letter of issuance with your new tax license number on it, as well as the necessary quarterly tax forms to be filed.
There is NO FEE TO OBTAIN a permanent KYU tax license number, but you are still responsible for the quarterly mileage tax. You may apply online for a permanent KYU number through the Motor Carrier Portal or through the mail with a paper application.
Register and obtain a KYU number online using the Motor Carrier Portal or use the Kentucky Trucking Application (TC 95-1) to apply by mail. Allow 10 to 14 business days for applications mailed to this office.

Commonly Made Mistakes

​​​
Please make sure that you have received your certificate of authority from the FMCSA before you apply online or send in the application. If you have always been an intrastate or private motor carrier you don’t have to worry about this.
Please check your current US DOT record to make sure that all information matches by checking the carrier snapshot for your company at the FMCSA SAFER web site at http://safer.fmcsa.dot.gov/. To update your information if it is currently incorrect, visit the FMCSA website or call FMCSA at (800) 832-5660.
When mailing the application, please include an original signature, representative title, and date in Section 7 before mailing the application. Unfortunately, all applications without an original signature must be rejected. Copied signatures, stamped signatures, faxed signatures, and POA signatures without a copy of the power of attorney attached will result in the application being rejected as well.
Please read all sections and the instructions carefully. The required sections are marked “Required”. If you are still confused as to what needs to be completed, please call our office at (502) 564-1257 before you submit the application.
Please make sure all vehicle information is completed in Section 3. This includes the plate number, state of registration, complete VIN number, unit number, year, make, and gross weight. Vehicles licensed in Kentucky, must also include the title number.
For in-state carriers, please call our office at (502) 564-1257 if you have previously had credentials with the KY Division of Motor Carriers before you submit a new application. For out-of-state carriers, please make sure that your US DOT number, and motor carrier authority (if applicable) are both active. The Unified Carrier Registration must also be completed before submitting an application.
Kentucky Intrastate For-Hire Authority is for carriers that pick up and deliver the same cargo within Kentucky. Out of state carriers that are for-hire that only transport cargo across state lines using the motor carrier authority from FMCSA, are not required to have this authority. Out of state carriers that are for-hire and do both intrastate and interstate transportation of carrier, will be required to complete Section 6 and submit the applicable fee and Form E insurance filing. The Unified Carrier Registration vehicle fees must be paid before applying for this authority.
Kentucky based companies that transport cargo as an intrastate carrier only and apply for intrastate for-hire authority must submit the $25 application fee and the $10 per vehicle fee with the application. Carriers that transport cargo as an intrastate carrier and an interstate carrier and apply for intrastate for-hire authority must submit the $25 application fee regardless of the company’s base state.
The proof of insurance card is not the same as a Form E insurance filing. The original Form E must come directly from the insurance carrier to our office by mail or electronically through the National Online Registries (NOR) website. Faxed copies will not be processed. If the insurance carrier does not know what a Form E is, please have them call our office at (502) 564-1257.
PLEASE allow 10 - 14 business days for processing of any incoming application. Sending your application Fed Ex, UPS, or overnight mail will only save you on the mailing time; NOT the processing time. Additional time may be required to process for-hire authorities if the Form E is not already in our office.
Please read the application carefully. Not all of it will apply to you. You will only need to send money if you are applying for some type of for-hire authority through Kentucky. All other credentials do not have an application fee.
