Section R865-19S-72 - Trade-ins and Exchanges Pursuant to Utah Code Ann. Section 59-12-102A. An even exchange of tangible personal property for tangible personal property is exempt from tax. When a person takes tangible personal property as part payment on a sale of tangible personal property, sales or use tax applies only to any consideration valued in money which changes hands.B. For example, if a car is sold for $8,500 and a credit of $6,500 is allowed for a used car taken in trade, the sales or use tax applies to the difference, or $2,000 in this example. Subsequently, when the used car is sold, tax applies to the selling price less any trade-in at that time.C. An actual exchange of tangible personal properties between two persons must be made before the exemption applies. For example, there is no exchange if a person sells his car to a dealer and the dealer holds the credit to apply on a purchase at a later date; there are two separate transactions, and tax applies to the full amount of the subsequent purchase if and when it takes place.Utah Admin.
