Kentucky Car Sales Tax, Trade-In Credit, and Out-of-State Rules

Short answer

Kentucky charges 6%, no local add-ons instead of an ordinary sales tax. Kentucky taxes the price after the trade-in is deducted. Kentucky exempts out-of-state buyers only under specific conditions. Kentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. This applies to a retail dealer purchase; lease deals and private-party sales follow their own rules in most states.

Sales tax rate on vehicles6%, no local add-ons[1]
Trade-in creditKentucky 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.[2]
Selling to an out-of-state buyerKentucky exempts out-of-state buyers only under specific conditions. the vehicle is never titled or registered in Kentucky. The usage tax attaches at county-clerk titling, so a buyer who titles in another state owes that state, not Kentucky.[1]
Credit for tax paid to another stateKentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. No credit for tax paid to Georgia on vehicles purchased after March 1, 2013, because Georgia's title ad valorem tax gives no reciprocal credit for Kentucky tax. Where the buyer has no proof of tax paid, Kentucky can only presume credit for states on its published list, never for another country and never on leased vehicles. Exception: no full credit for tax paid to Georgia.[2]

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.

Selling to an out-of-state buyer in Kentucky

Kentucky exempts out-of-state buyers only under specific conditions. the vehicle is never titled or registered in Kentucky. The usage tax attaches at county-clerk titling, so a buyer who titles in another state owes that state, not Kentucky.[1]

Whatever the tax treatment, the desk owns what happens next: title in transit, tag on the car, registration filed in another state.

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 rule above. Kentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. No credit for tax paid to Georgia on vehicles purchased after March 1, 2013, because Georgia's title ad valorem tax gives no reciprocal credit for Kentucky tax. Where the buyer has no proof of tax paid, Kentucky can only presume credit for states on its published list, never for another country and never on leased vehicles. 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.[3] You do not need a Kentucky driver's license to title and register here. A Kentucky ID card or a Social Security card is accepted at the county clerk, along with proof of Kentucky insurance issued within 45 days, and for a vehicle coming from another state, proof of a passed sheriff's VIN inspection.[4]

Bordering states

Cross-border deals from Kentucky most often involve Illinois, Indiana, Missouri, Ohio, Tennessee, Virginia and West Virginia. No two pairings behave the same; run the exact combination through 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.[5]

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]

Kentucky car sales tax questions

Kentucky charges 6%, no local add-ons instead of an ordinary sales tax. The charge comes due when the vehicle is titled or registered, not at the desk, and trade-in treatment sets the taxable figure.

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. That rule moves the taxable price, which is why the same deal pencils out to different tax in different states.

Kentucky exempts out-of-state buyers only under specific conditions. the vehicle is never titled or registered in Kentucky. The usage tax attaches at county-clerk titling, so a buyer who titles in another state owes that state, not Kentucky.

Kentucky credits sales tax legally paid to another state, so the same dollars are not taxed twice. No credit for tax paid to Georgia on vehicles purchased after March 1, 2013, because Georgia's title ad valorem tax gives no reciprocal credit for Kentucky tax. Where the buyer has no proof of tax paid, Kentucky can only presume credit for states on its published list, never for another country and never on leased vehicles. Exception: no full credit for tax paid to Georgia.

Start with the sale price and subtract the trade-in allowance (Kentucky credits it in full), then multiply by 6%, no local add-ons. The Kentucky calculator on this page runs those steps with the verified figures and shows the out-the-door estimate before title and registration fees.
