Kentucky Form 71A100, the Affidavit of Total Consideration Given for a Motor Vehicle, is used to document the complete value exchanged when a motor vehicle is purchased or transferred. The form records information about both the seller and buyer, identifies the vehicle involved in the transaction, reports any trade-in vehicle and trade-in allowance, and calculates the total consideration given for either a new or used vehicle. For purposes of the form, total consideration is broader than simply the cash paid to the seller. It may include cash, financed amounts, and the monetary value of other property or items provided as part of the transaction, as well as amounts attributable to vehicle equipment and accessories. Certain amounts, including rebates, service contracts, extended warranties, and finance charges, are excluded from the total consideration calculation. Both the seller and buyer certify the information, and the affidavit includes separate attestation sections for the signatures to be sworn before an authorized official. Completing the affidavit accurately matters because an incomplete form may cause Kentucky motor vehicle usage tax to be calculated using another prescribed vehicle value rather than the consideration reported by the parties.
When Is Form 71A100 Used?
Form 71A100 is used when the total consideration paid or given for a motor vehicle needs to be documented for Kentucky motor vehicle tax purposes.
The form accommodates both:
- New vehicle transactions.
- Used vehicle transactions.
It also contains a separate section for a vehicle accepted as a trade-in.
Because the form is an affidavit, the seller and buyer are affirming that the reported selling price, rebates, trade-in allowance, and total consideration accurately represent the transaction.
How To File Form 71A100
Complete all sections that apply to the vehicle transaction and make sure both the seller and buyer complete the required certification and attestation areas.
The form itself does not provide a specific mailing address or separate filing destination. It is intended to accompany the applicable Kentucky motor vehicle transaction documentation when the affidavit is required. Follow the submission procedure provided by the office handling the title, registration, or motor vehicle usage tax transaction.

- Seller’s full legal name.
- Seller’s Social Security Number or Federal Identification Number.
- Seller’s address and telephone number.
- Buyer’s full legal name.
- Buyer’s Social Security Number or Federal Identification Number.
- Buyer’s address and telephone number.
- Date of purchase.

The form provides the basic calculation:

However, the reported consideration must also reflect any additional value that is considered part of the transaction under the affidavit’s total-consideration definition.
What Is Included in Total Consideration Given?
The meaning of total consideration given is important when completing either the new or used vehicle section.
The amount can include:
- Cash paid toward the vehicle.
- Amounts financed.
- The monetary value of other items or property provided as part of the transaction.
- Consideration provided at the time of purchase.
- Consideration that will be provided at a later date as part of the transaction.
- Amounts paid or given for standard equipment.
- Amounts paid or given for optional equipment.
- Accessories included in the transaction.
The form gives examples of other property that could have monetary value in the transaction, including boats, trailers, and other items.
Do not report only the cash down payment when other consideration was also provided.
What Is Not Included in Total Consideration?
The affidavit specifically excludes certain amounts from total consideration.
Do not include the value of:
- Rebates.
- Service contracts.
- Extended warranties.
- Finance charges.
These amounts should not be added to total consideration merely because they appear elsewhere in the transaction paperwork.
Seller and Buyer Declaration
Before signing the affidavit, both parties should review the transaction information carefully.
The seller and buyer declare that, to the best of their knowledge and belief, the information provided correctly represents:
- The total consideration given in exchange for the vehicle; and
- The trade-in allowance granted for any vehicle traded as part of the transaction.
Because this is a sworn affidavit, the figures should reflect the actual transaction rather than an estimated, reduced, or artificially assigned amount.
Notice About False Statements
The form contains a significant legal warning concerning false information.
It states that making a false statement regarding the total consideration paid is a Class D felony and carries a minimum fine of $2,000 under the statute cited on the affidavit.
For that reason, both parties should verify the purchase price, trade-in allowance, rebates, and other consideration before signing.
What Happens If the Affidavit Is Incomplete?
The affidavit includes a specific notice to buyers about incomplete forms.
If the affidavit is incomplete, the vehicle’s taxable value may be determined using:
- The MSRP for a new vehicle; or
- The retail value from the prescribed reference manual for a used vehicle.
The buyer may then become responsible for additional tax as well as any applicable penalty and interest.
This makes it important to complete every applicable identification, transaction, calculation, signature, and attestation field before filing.

How To Calculate Total Consideration
The exact calculation depends on whether the vehicle is new or used and whether a trade-in or rebate is involved.
New Vehicle Example Structure
For a new vehicle, the form provides fields for:
Selling Price
minus
Rebates
minus
Trade-in Allowance
to arrive at:
Total Consideration Given
Any other consideration that must be included under the form’s definition should also be properly reflected in the transaction amount.
Used Vehicle Example Structure
For a used vehicle, the calculation shown on the form is:
Selling Price
minus
Trade-in Allowance
equals
Total Consideration Given
Again, total consideration should represent the complete value exchanged rather than only the cash portion of the transaction.
