CaliforniaSales and use tax

How does California tax an advance-exchange repair program when the customer gets a different refurbished unit back?

The short answer

California taxes the exchange fee as a sale of the refurbished unit, and adds the surrendered unit's value when the two are not the same kind of property. A repair in the ordinary sense returns the customer's own property, and tax then reaches only the parts, with repair labor outside the measure (Cal. Code Regs., tit. 18, section 1546(b)(1), (2)). An advance exchange does not return the customer's property. Where the refurbished unit is "exactly the same kind of property" as the one surrendered, Regulation 1546(b)(4) taxes the amount charged for the reconditioned unit, with no deduction for labor. Where it is not, the annotations of the California Department of Tax and Fee Administration (the Department) treat the surrendered unit as a trade-in, and Regulation 1654(b)(1) adds the trade-in allowance to the measure of tax. Exchanges furnished under an included warranty or a separately sold service plan follow the warranty and maintenance contract rules instead.

Three ways to characterize the same swap

An advance-exchange program reverses the order of an ordinary repair. The customer reports a failure, the seller ships a refurbished unit at once, and the customer sends the failed unit back within a fixed number of days. The failed unit is repaired and joins the pool from which later replacements are drawn. Nothing returns the customer's own property, and that is what moves the transaction out of the repair rules.

A "sale" includes "[a]ny transfer of title or possession, exchange, or barter" of tangible personal property for a consideration (Rev. and Tax. Code section 6006(a)). Gross receipts are measured without deduction for "labor or service cost," and include "[a]ny services that are a part of the sale" and "[a]ny amount for which credit is allowed by the seller to the purchaser" (Rev. and Tax. Code section 6012(a)(2), (b)(1), (b)(3)). Against that framework, the same swap can be read three ways.

The first reading is a repair. A repairer is the retailer of the parts it furnishes if their retail value is more than 10 percent of the total charge or if it charges for them separately, and tax then applies to the parts alone (section 1546(b)(1)); otherwise it is the consumer of the parts and pays tax on its own purchase (section 1546(b)(2)). Repair labor is not taxed under either branch. This reading fits a depot repair that returns the customer's own unit, not an advance exchange.

The second reading is an exchange of used for reconditioned property. Regulation 1546(b)(4) provides: "If the method of repairing or reconditioning certain tangible personal property involves commingling property delivered to a repairman or reconditioner with similar property so that the customer receives repaired or reconditioned property which may not be the identical property delivered to the repairman or reconditioner but which is exactly the same kind of property or derived from exactly the same kind of property as that so delivered, tax applies to the amount charged by the repairman or reconditioner for the repaired or reconditioned property." The measure is the whole charge, because the customer is buying a reconditioned item, not a service performed on its own property. A published Court of Appeal decision applied the paragraph to a commingled exchange of depleted tanks for similar tanks regenerated at the taxpayer's plant and held the regeneration charges taxable (Continental Water Conditioning Co. v. State Bd. of Equalization (1989) 207 Cal.App.3d 783).

The third reading is a sale of a refurbished unit with a trade-in. Regulation 1654(a) confirms that sale and purchase "include exchange and barter," and Regulation 1654(b)(1) requires a retailer accepting a trade-in to "include in the measure of tax the amount agreed upon between seller and buyer as the allowance for the merchandise traded in." Should the Department "find that the allowance stated in the agreement is less than the fair market value, it shall be presumed that the allowance actually agreed upon is such market value" (section 1654(b)(1)).

What "the same kind of property" means for a refurbished unit

The line between the second and third readings is drawn in the Department's annotations, which summarize legal rulings issued by the Department and its predecessor, the State Board of Equalization. Annotation 315.0410 (November 29, 1990) states: "In order for Regulation 1546(b)(4) to apply, the reconditioned property must be virtually identical to the used property delivered by the customer." Such a transaction "is the functional equivalent of one in which the customer's own property is reconditioned and tax applies only to the value added or exchange price of the reconditioned property. If the property delivered by the customer is not virtually identical, it is a 'trade-in' under Regulation 1654(b)(1)."

The older annotations apply the rule to commingled pools. Rechromed bumpers are taxable where the trade commingles them, but nontaxable as a repair where the rechromer "keeps adequate records to prove that the bumper returned is the identical bumper sent in" (Annotation 315.0360, January 29, 1969). The closest analogue to a modern program is a manufacturer's pool of engine modules, from which removed modules were replaced for a fixed participation charge; the swaps were "regarded as the exchange of used for reconditioned similar property," taxed on the pool charge (Annotation 315.0353, September 21, 1983). Whether the seller refurbishes the units itself or uses a subcontractor does not matter: "The focus is on the character of the goods, not on the act of reconditioning" (Annotation 315.0415, May 9, 1990).

An example shows how much turns on the characterization. A manufacturer of commercial label printers offers California customers, outside the warranty period, an advance exchange: for a flat $450 it ships a refurbished printer the next business day, and the customer returns the failed one within 15 days. It also offers depot repair, returning the customer's own printer with an invoice showing $120 of separately stated parts and $330 of labor.

  • Depot repair, own unit returned. The manufacturer is the retailer of the parts because they are separately stated, and tax applies to $120. The $330 of labor is outside the measure.
  • Advance exchange, same model. A refurbished printer of the same model and configuration fits the words "exactly the same kind of property." Tax applies to the $450 charged for the reconditioned unit. Nothing is carved out for labor, and the failed printer the customer surrenders is not added.
  • Advance exchange, upgraded model. If the customer elects a current-generation printer for $700 and surrenders the failed older model, the units are not virtually identical. The transaction is a sale of the newer printer with a trade-in, and the measure is $700 plus the allowance for the failed printer. If the manufacturer sells the same refurbished current model outright for $1,500, the $800 difference is one available measure of that allowance, and Regulation 1654(b)(1) otherwise supplies only a fair market value presumption.

Exchanges under warranties and service plans

Many advance exchanges carry no separate price because a warranty or service plan covers them. Regulation 1655 sorts those by whether the coverage was optional.

A warranty is mandatory "when the buyer, as a condition of the sale, is required to purchase the warranty or guaranty contract from the seller" (section 1655(c)(1)). A standard warranty included in the price of the product falls on that side. The sale of the product includes replacement parts furnished under the guaranty or mandatory warranty, and "[t]he sale of the replacement parts and materials to the seller furnishing them thereunder is a sale for resale and not taxable" (section 1655(c)(2)). An exchange unit shipped under an included warranty is part of the original, already taxed sale, and mandatory maintenance contracts follow the same rule (section 1546(b)(3)(B)). Annotation 315.0297 (November 10, 1994) applies the same division to warranty work done through service centers: "If the warranty is mandatory, the parts are regarded as having been sold with the original sale of the equipment."

An optional plan, one the buyer "is not required to purchase" from the seller (section 1546(b)(3)(A)), reverses the roles. The person obligated to furnish parts, materials and labor "is the consumer of the materials and parts furnished and tax applies to the sale of such items to that person" (section 1655(c)(3); see also section 1546(b)(3)(C)). If that person bought the property for resale or from outside California without paying tax, it "must report and pay tax upon the cost of such property to him or her when he or she appropriates it to the fulfillment of the contract of warranty" (section 1655(c)(3)). The customer pays no tax on the exchange unit; the plan provider pays it on its cost.

Annotation 490.0477 (August 5, 1988) applies that rule to an advance-exchange plan: under an optional service contract, a firm shipped next-day replacements for failed equipment and added the repaired failed units to its replacement inventory. The firm was "the consumer of property used to fulfill its obligations under the contract." Because both the repair shop and the shipping division were outside California, the firm completed its obligation when it delivered the replacement to the carrier, "the 'use' occurs outside of California," and no use tax was due. The annotation adds one exception: "If the unit is not defective and a charge is made, the firm must collect use tax on exchange units shipped to California." A customer charged because its returned unit had no defect has bought the replacement.

Per-incident fees are a third pattern. A plan or warranty that requires the customer to pay a set amount for each exchange has a deductible within the meaning of section 1655(c)(4), which is "subject to tax measured by the amount of the deductible allocable to the sale of tangible personal property to the customer." Unless the contract states otherwise, "the person providing the warranty contract is liable for any tax or tax reimbursement otherwise payable by the customer with respect to that deductible." Since an exchange delivers a whole unit, little in a per-exchange fee is allocable to anything but property.

Core deposits and units that never come back

Because the replacement ships first, programs secure the return with a deposit, a card authorization, or a charge if the unit is not received. The annotations keep the deposit outside the measure of tax only on conditions: the transaction must be "clearly understood and designated to be an exchange," and the customer must deliver the worn part and receive the deposit back; the annotation adds that the deposit should be booked separately as a deposit (Annotation 315.0380, January 19, 1950). If the worn part is not delivered, "the transaction will be regarded as a straight sale of the reconditioned part," and tax applies "to the full retail sales price," the retained deposit included (same).

A retailer may protect itself by charging tax reimbursement on the deposit, but that reimbursement "must be returned to the customer with the deposit, otherwise it constitutes excessive tax reimbursement under section 6901.5" (Annotation 315.0400, November 4, 1964, and September 29, 1989). Excess reimbursement not returned to the customer is remitted to the state (Rev. and Tax. Code section 6901.5). For reconditioned parts, a customer who returns the core is "entitled to a credit or refund of the core deposit plus tax paid with respect to it" (Annotation 315.0370, February 27, 1980).

In the printer example, if the program charges an additional $750 when the failed printer does not arrive within 15 days, the measure stays at $450 when it comes back and becomes $1,200, a straight sale, when it does not.

Defect credits are a separate matter. Regulation 1655(b)(1) excludes "[a]mounts credited or refunded by sellers to consumers on account of defects in merchandise sold," but "[i]f, however, defective merchandise is accepted as part payment for other merchandise and an additional allowance or credit is given on account of its defective condition, only the amount allowed or credited on account of defects may be excluded from taxable gross receipts. The amount allowed as the 'trade-in' value must be included in the measure of tax." Annotation 490.0325 (January 16, 1985) applies the rule to a replacement aircraft, measuring the tax by the additional payment "plus the trade-in value of the aircraft." The credit is limited to defects present at sale: a compressor that fails "as the result of many years of productive use and not because of a defect inherent in it when it was first sold" is not eligible, and any credit allowed for it on a replacement "would be in the nature of a trade-in" (Annotation 490.0748, January 28, 1969). An out-of-warranty exchange of a unit worn out in service rarely qualifies.

Where the depot sits

A refurbished unit sold from a California depot to a customer outside the state is exempt from sales tax if, "pursuant to the contract of sale," it "is required to be shipped and is shipped to a point outside this state by the retailer," by the retailer's own facilities or by delivery to a carrier (Rev. and Tax. Code section 6396). A unit sold from a depot outside California to a California customer is not a California sale, but its use here is subject to use tax, which a retailer engaged in business in California must collect from the purchaser (Rev. and Tax. Code section 6203(a)). Annotation 315.0215 (October 31, 1988) applies the same rules to repairs at service centers on either side of the state line.

Optional plans produce an asymmetry. Annotation 490.0477 found no California use where an out-of-state division delivered replacements to the carrier outside California. Annotation 315.0766 (December 6, 1993) reaches the opposite result for a company shipping refurbished parts from California under optional maintenance contracts: when it ships them to out-of-state customers, "tax applies at the time of shipment," because passing title in California is "a complete use of the part in meeting its obligation under the optional warranty," outside the section 6009.1 exclusion. A California depot fulfilling optional plans therefore owes use tax on its cost of the exchange units it ships, including those bound for customers in other states, while a depot outside California fulfilling the same plans for California customers may owe none.

What the guidance leaves open

Much of the Department's treatment of exchange programs is found in annotations, not in the regulation itself. Annotations "do not have the force and effect of law," and following one "is not reasonable reliance upon written advice" for relief from tax, interest and penalty, subject to exceptions in Regulations 1705 and 4902 (Cal. Code Regs., tit. 18, section 35101). They show how the Department has reasoned, not what it must conclude.

Several questions remain open for refurbished equipment. The regulation asks whether the replacement is "exactly the same kind of property," and the annotation asks whether it is "virtually identical." Neither addresses a same-model replacement with a later hardware revision, a different configuration, or a lower cosmetic grade, the ordinary variations within a refurbished pool. Where a program states no trade-in allowance, nothing in Regulation 1654 fixes how the allowance is measured beyond the fair market value presumption. And where a plan provider refurbishes its own returned units and then uses them to fulfill optional plans, the "cost of such property" on which section 1655(c)(3) imposes tax could be read as the parts consumed in refurbishment or as some value of the unit as a whole; no published guidance located for this article resolves the point.

Practice notes

The characterization is set by the program terms and the invoice, not by the name of the service. A program that ships replacements of the same model and configuration, describes the transaction as an exchange, and books core deposits separately fits Regulation 1546(b)(4), with tax on the exchange charge. A program that lets the customer choose a different model, or ships whatever unit is in stock, leaves the surrendered unit open to treatment as a trade-in. Labor is not separable from an exchange charge, so a seller that bills an exchange as repair labor and collects tax only on parts is exposed on the difference. Warranty exchanges turn on whether the coverage was included in the sale or sold as an option, which moves the tax from the customer's charge to the provider's cost. Unreturned cores, tax reimbursement on deposits, per-incident fees and units found not defective each call for their own billing treatment, and a California depot serving optional plans carries a use tax cost on units it ships out of state that an out-of-state depot does not.
