Free Kentucky Used Car Bill of Sale
Buying a used car in Kentucky means navigating the 6% Motor Vehicle Usage Tax, which is calculated on NADA book value — not necessarily what you paid. On a used car with a $20,000 book value, that is $1,200 in usage tax even if you negotiated the price to $17,000. You must also clear any existing lien and complete the title transfer at your County Clerk within 15 days.

Kentucky Used Car Bill of Sale — What You Need to Know
Sales Tax Details
Kentucky Motor Vehicle Usage Tax: 6% of the higher of purchase price or NADA book value. Buyers who pay below market value are frequently surprised when the County Clerk taxes the transaction at book value.
Exemption: Transfers between immediate family members may qualify for reduced usage tax — confirm with your County Clerk.
Inspection Requirements
Kentucky does not require a statewide safety inspection for used vehicle purchases.
Kentucky Used Car Sale — Step-by-Step Checklist
- Verify the seller's name matches the name on the title before signing anything
- Request a lien release letter from the seller's lienholder if any loan is shown on the title
- Complete odometer disclosure on the title (required by federal law)
- Draft a bill of sale documenting the agreed purchase price, vehicle details, and both parties' signatures
- Look up the NADA book value before closing so you know the actual tax liability — not just the negotiated price
- Take the assigned title, bill of sale, and proof of insurance to the County Clerk within 15 days
- Pay the 6% usage tax on the higher of purchase price or book value and receive your new Kentucky title
Common Pitfalls
- Underestimating the usage tax — Kentucky taxes on book value when the sale price is below NADA, meaning the real tax bill can be significantly higher than 6% of what you paid
- Accepting a title that still shows an active lienholder — you cannot legally transfer a title with an unresolved lien
- Skipping the odometer disclosure — federal law requires it for most vehicles under 10 years old and under 16,000 lbs gross weight, and an incomplete title will be rejected
- Waiting past 15 days to visit the County Clerk — late transfers incur penalties that accumulate quickly
- Not getting a signed bill of sale — without it you have no documented proof of the sale price or 'as-is' terms if a dispute arises
Pro Tip
Document the exact purchase price in your bill of sale and bring both the bill of sale and the NADA printout to the County Clerk — if the Clerk's book value differs from yours, having documentation of a legitimate arm's-length transaction can support an appeal.
