Kentucky KYU registration and filing help
Kentucky KYU is a weight-distance tax license for carriers operating qualifying heavier vehicles on Kentucky roadways. A permanent KYU account requires quarterly online returns and current vehicle inventory; eligible occasional operations may use a temporary KYU permit under current Kentucky rules.
Register before a qualifying Kentucky operation
The carrier should confirm the combined licensed weight, route, frequency, authority status, and whether a permanent KYU license or eligible temporary permit fits the operation.
Maintain the vehicle inventory and quarterly return
Kentucky’s current guidance requires electronic quarterly reporting for an active KYU license, including zero miles when no qualified travel occurred. Vehicle inventory and Kentucky distance must be kept current.
- Kentucky ID Gateway and Motor Carrier Portal access
- Legal entity, authority, USDOT, and contact details
- Qualified vehicle inventory
- Kentucky taxable mileage by quarter
- Filed return, payment, and confirmation
KYU is separate from IFTA
KYU is based on Kentucky mileage for vehicles above the state threshold. IFTA is a separate fuel-tax program with a different qualification threshold and tax calculation. A vehicle can be subject to both.
What Mann does—and what the agency decides
Mann Registration can help collect facts, prepare filings, organize records, and track follow-up. Mann is an independent private service provider, not Kentucky Transportation Cabinet Division of Motor Carriers, and cannot approve an application, change an agency record without the required process, give legal or tax advice, or guarantee timing or results.
