Short answer
Kentucky taxes vehicle sales at 6%, no local add-ons. Kentucky taxes the price after the trade-in is deducted. The trade-in must itself be a motor vehicle registered in the buyer's name and handed over at the time of purchase, and the allowance has to be attested in a notarized affidavit. On used vehicles the taxable price cannot fall below 50 percent of the difference between the two vehicles' book trade-in values. Kentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. Exception: no full credit for tax paid to Georgia. That summary is for a retail purchase from a dealer, and most states apply different rules to leases and private-party sales.

From the desk
Kentucky's motor vehicle usage tax is its own animal, collected at the county clerk when the title moves. The desk quotes it like sales tax, but the rules underneath, especially on trades and transfers, follow the usage-tax statute.

The desk's job doesn't end at the tax line. Somebody still has to chase the title, the temp tag, and the buyer's home-state registration, and Voltra's title tracking keeps that chase on one screen.
Buying in Kentucky from out of state
If you live in another state and buy in Kentucky, the deciding rule is where the vehicle gets registered: your home state's tax applies at registration, and what happens at the Kentucky sale depends on the row above. Kentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. Exception: no full credit for tax paid to Georgia.[2]
Registration and temp tags
A Kentucky dealer selling to a buyer who will title and register in another state equips the vehicle with a temporary tag good for 60 days from the date of delivery. The tag costs $3, of which the county clerk keeps $2. Validity: 60 days.[3]
Bordering states
Cross-border deals from Kentucky most often involve Illinois, Indiana, Missouri, Ohio, Tennessee, Virginia and West Virginia. The combination decides the outcome, so check both states in the out-of-state checker.
Vehicle-type exceptions
Recreational vehicles count as motor vehicles for usage tax: motor homes, travel trailers, fifth wheels, pull-behind campers and pop-up camping trailers that contain living quarters and must be licensed for highway use. Mopeds, road rollers and rail vehicles fall outside the definition.[4]
How Kentucky actually levies this
Kentucky does not charge ordinary sales tax on a vehicle purchase. It charges a 6% motor vehicle usage tax under KRS 138.460, imposed on the use of the vehicle in Kentucky and collected by the county clerk when the vehicle is titled or registered, not by the dealer at the point of sale.[1]
