Each party should receive a clean title for the vehicle they are accepting. Confirm that neither vehicle has an outstanding lien before trading.
Buyer guidance
At a dealership, the trade-in allowance is a negotiated discount on the purchase price. The dealer will handle the title transfer paperwork. For private trade-ins, ensure you receive a bill of sale that accurately states the value of the vehicle you are trading in — this determines your sales tax liability on the net purchase price in most states.
Legal considerations
Many states allow a sales tax credit for trade-in value (reducing taxable amount to the difference between new vehicle price and trade-in allowance). This "tax swap" benefit is governed by state law (e.g., available in most states, but not California, Michigan, or Hawaii for full-price vehicles). Each vehicle's lien (if any) must be paid off as part of the exchange.
