A Kentucky private vehicle sale centers on a properly assigned and notarized title, not a bill of sale alone. The buyer must complete the ownership transfer within 15 days, and Kentucky generally collects a 6% Motor Vehicle Usage Tax when ownership changes.

Kentucky Bill of Sale Quick Facts

Does Kentucky Require a Bill of Sale?

A bill of sale is useful in Kentucky, but it does not replace the certificate of title for a normal titled passenger vehicle.

The seller must properly assign the Kentucky title to the buyer. For an ordinary Kentucky-to-Kentucky transfer, the seller signs the back of the title in the presence of a notary.

The Kentucky Transportation Cabinet vehicle titling guidance states:

“the title must be transferred to the new owner within 15 days.”

A separate bill of sale gives both parties a clear record of the purchase price, delivery date, mileage and payment terms. It is particularly useful when the transaction later needs to be documented for tax, an incomplete transfer or a dispute.

For a complete private-sale record, include:

• Buyer and seller names and addresses.

• Vehicle year, make and model.

• Complete VIN.

• Sale date.

• Actual purchase price.

• Odometer reading.

• Buyer and seller signatures.

Do not use a bill of sale as a substitute for a missing Kentucky title unless a specific Kentucky title procedure allows alternative ownership evidence.

Which Documents Does the Kentucky Buyer Need?

For a normal in-state private purchase, prepare:

• Properly assigned Kentucky title: The seller’s signature must be notarized.

• Proof of Kentucky insurance: Current proof should meet the state’s timing requirements.

• Identification: Kentucky driver’s license, Kentucky ID or another accepted identification document.

• Tax documentation: Purchase-price information needed to calculate Motor Vehicle Usage Tax.

• Lien release: Required when an unreleased lien appears on the title.

• TC 96-182: Application for Kentucky Certificate of Title or Registration when the transaction requires it.

Kentucky’s current guidance notes that some titles issued before 2000 may require TC 96-182 to complete the ownership transfer.

Check the title before exchanging money. White-out, erasures, overwritten information or crossed-out entries can create a title problem that requires additional notarized documentation.

Does a Kentucky Bill of Sale Need Notarization?

Kentucky’s most important notarization requirement concerns the title assignment.

For a Kentucky-to-Kentucky sale, the seller signs the back of the certificate of title in front of a notary. Do not have the seller sign the title days earlier and assume the buyer can arrange notarization later.

Kentucky also uses notarized affidavits to establish the actual consideration paid for Motor Vehicle Usage Tax purposes.

A generic sale receipt does not replace those notarized documents.

The practical rule is:

Bill of sale: Keep one as a transaction record.

Kentucky title: Complete the required seller signature before a notary.

Affidavit of consideration: Notarize it when used to establish the taxable purchase amount.

Other documents, including powers of attorney and special title affidavits, have their own execution rules.

Kentucky Gives the Buyer 15 Days to Transfer the Title

The buyer must initiate the title transfer within 15 days of the transaction.

Do not treat this as a suggested filing period. Kentucky’s title and registration rules establish the 15-day window for newly acquired vehicles.

Complete the county clerk transaction as soon as practical because title errors, liens or insurance issues can prevent the transfer from being processed immediately.

The buyer should check that:

• The VIN matches the actual vehicle.

• The seller is the titled owner.

• The seller’s signature is properly notarized.

• The mileage disclosure is correct.

• The purchase price is accurately reported.

• Existing liens have been released.

A vehicle coming from Tennessee may carry different seller documents. Check the Tennessee bill of sale and title requirements before bringing those documents into Kentucky’s county-clerk process.

What Happens if the Buyer Does Not Transfer the Title?

Kentucky gives the seller an important protection when the buyer fails to complete the transfer.

If the buyer has not submitted the required title documents to a county clerk within 15 days, the seller must submit TC 96-3, Affidavit of Incomplete Transfer.

The form must be signed and notarized.

Once the county clerk processes it, the vehicle title record is surrendered or restricted so another registration transaction cannot proceed normally until the ownership transfer is resolved.

This helps protect a seller from leaving an active vehicle record indefinitely connected to a car that has already been delivered to someone else.

Keep:

• A copy of the assigned title.

• The bill of sale.

• Buyer contact information.

• Payment records.

• TC 96-3 and county-clerk receipt if it becomes necessary.

Do not depend only on a text message from the buyer saying that the transfer will be completed later.

How Much Tax Applies to a Kentucky Private Vehicle Purchase?

Kentucky imposes a 6% Motor Vehicle Usage Tax when vehicle ownership is transferred.

The Kentucky Department of Revenue Motor Vehicle Usage Tax guidance explains that the tax is collected by the county clerk when the vehicle is transferred or first registered in Kentucky.

For a used vehicle, Kentucky generally uses the transaction amount documented through the required notarized affidavit of total consideration, subject to its minimum-value rules.

Straightforward examples at 6% are:

• $5,000 taxable value → $300

• $10,000 → $600

• $15,000 → $900

• $20,000 → $1,200

• $30,000 → $1,800

Title, registration, property tax and inspection charges are separate.

A Very Low Sale Price May Not Produce a Very Low Tax

Kentucky does not automatically accept every stated purchase price as the taxable amount.

For a used motor vehicle, the notarized consideration amount generally cannot be lower than 50% of the difference between the prescribed trade-in value of the purchased vehicle and the prescribed value of any vehicle actually accepted in trade.

For a simple cash purchase with no trade:

Assume the applicable reference value is $20,000.

The 50% floor is $10,000.

If the parties report a genuine purchase price of $8,000, the taxable retail price can still be subject to the $10,000 floor, producing $600 in usage tax rather than $480.

If the required notarized consideration affidavit is unavailable, Kentucky can use the value established through its prescribed vehicle reference system.

This is why an unusually low number written on a handwritten bill of sale does not necessarily control the Kentucky tax bill.

Can a Trade-In Reduce Kentucky Usage Tax?

Kentucky allows an applicable trade-in allowance to enter the Motor Vehicle Usage Tax calculation when the transaction qualifies and the allowance is properly documented.

The trade-in must be part of the actual transaction. Selling a vehicle separately to another person is not automatically the same as giving that vehicle to the seller as a trade.

The notarized consideration document should accurately state:

• Purchase price.

• Vehicle received in trade.

• Trade-in allowance.

• Total consideration.

Do not manufacture a trade-in value simply to lower the taxable amount. Kentucky’s valuation floor still applies.

What Title and Registration Fees Are Separate From Tax?

For a standard passenger transaction, Kentucky lists a $9 title fee and a $21 standard registration/plate fee.

Those amounts are not the buyer’s complete bill.

Additional costs can include:

• 6% Motor Vehicle Usage Tax.

• Annual motor vehicle property tax.

• Lien recording charges.

• Sheriff inspection for an out-of-state vehicle.

• Registration transfer charges.

• Specialty or personalized plate fees.

Kentucky assesses annual motor vehicle property tax separately from the transfer tax.

The person who owned the vehicle on January 1 can remain responsible for the applicable property tax even if the vehicle is sold later in the year. Sellers should not assume the tax disappears when the title is signed over.

What Happens to the Kentucky License Plate?

Kentucky changed its plate system in January 2024.

For an ordinary transfer involving an unexpired registration, the seller keeps the Kentucky license plate instead of leaving it on the sold vehicle.

The seller can transfer the plate and remaining registration to another personally owned vehicle of the same classification.

Kentucky lists a one-time $11 registration-transfer fee for that process.

Do not allow the buyer to leave with your plate attached simply because the plate still has months remaining on its registration.

A buyer registering the vehicle in Ohio must follow Ohio’s ownership process separately. The Ohio bill of sale and title guide covers that destination-state requirement.

What Changes When the Buyer Lives Outside Kentucky?

An out-of-state resident purchasing a privately owned Kentucky-titled vehicle may qualify for a Kentucky transit tag.

The current state program lists:

• Cost: $5.

• Validity: 15 days.

• Purpose: Allow an eligible nonresident purchaser to move the Kentucky vehicle to the buyer’s home jurisdiction.

The transit tag does not title or register the vehicle in the destination state.

Kentucky residents buying a vehicle outside the Commonwealth cannot use this Kentucky transit-tag program simply to bring the out-of-state purchase home. The seller’s state should provide the appropriate temporary authority.

When a Kentucky vehicle is sold to an out-of-state resident, follow the county-clerk instructions for the Kentucky plate and seller notification instead of assuming the buyer will handle every Kentucky record automatically.

Does an Out-of-State Vehicle Need a Kentucky VIN Inspection?

Yes. A vehicle coming into Kentucky on an out-of-state title generally requires a Sheriff’s Inspection before Kentucky title and registration.

The inspection confirms identifying information such as:

• VIN.

• Make.

• Model.

• Vehicle type.

• Ownership documentation.

The standard inspection fee is $5.

The buyer also needs the assigned out-of-state ownership document, TC 96-182, acceptable identification, Kentucky insurance and the applicable tax and fee payment.

If the issuing state does not use titles for that vehicle, Kentucky can accept the ownership document normally used by that jurisdiction, such as a registration or bill of sale, subject to the applicable notarization requirements.

Does Kentucky Require a Smog or Safety Inspection for Every Private Sale?

Kentucky does not impose a routine statewide emissions test or general mechanical safety inspection solely because a normal Kentucky-titled passenger car is sold privately.

Do not confuse this with the sheriff’s inspection required for an incoming out-of-state vehicle.

That inspection verifies vehicle identity and ownership information. It is not a complete mechanical inspection guaranteeing that the car is safe or free of defects.

Buyers should still obtain an independent pre-purchase mechanical inspection when vehicle condition is uncertain.
