How could franchisees tax real-estate signs bought complete, rented to brokers, and changed only by simple rider swaps?
They could pay tax on purchase price and rent tax-paid, or buy for resale and collect use tax on rent; simple rider swaps did not change the form.
What lease-tax choices did franchisees have for complete real-estate signs changed only by simple rider swaps?
They could pay tax on purchase price and rent tax-paid, or buy for resale and collect tax on rent, assuming same form and no other use.
Did selling future per-scan royalty rights change the original medical-equipment seller's sales-tax reporting duty?
No. The royalty-right sale was an intangible transfer, while the equipment seller still owed tax as contract royalties became definite.
Was an advertisement designer's sale taxable when the out-of-state client received only a proof and bill, but the final composite film went to a California magazine?
Yes. Delivering the composite-film final product to the California magazine on the client's behalf was a California transfer, so the sale was taxable despite the client's out-of-state residence.
Did a free weekly shopper become part of an exempt daily newspaper because both used substantially the same advertising and news content?
No. The shopper had to qualify independently; if it failed the 90 percent advertising test, the publisher consumed its paper and ink, while advertising-space sales remained services.
How did California allocate identical advertising inserts between a taxable weekly shopper and an exempt daily newspaper?
Printer charges were taxable for inserts placed in the shopper and exempt for copies incorporated into the newspaper, if documentation supported the proportion assigned to each use.
Did a hospital-supply contract make the purchasing company the hospital's agent rather than a reseller?
No. Maximum-price protection, delayed reimbursement, financing, ownership language, and retained risk of loss showed that the company bought and resold the supplies.
Was a company the hospital's purchasing agent when it financed, warehoused, insured, and guaranteed maximum prices for hospital supplies?
No. The full contract showed a purchase-for-resale arrangement because the company did not pass through the exact supplier cost and retained seller-like obligations.
Who was treated as the consumer of drugs and medicines used in a veterinarian's professional services?
The veterinarian. Supplier sales to the licensed veterinarian were taxable, while the veterinarian's charge for those drugs and medicines was not.
Were intraocular surgical replacement lenses and their replacement parts exempt?
Yes. The 1988 annotation-update memorandum classified intraocular lenses and their replacement parts as exempt.
When were splints and their replacement parts exempt in California?
When designed to be fully worn by the patient as a brace, support, or correction for body structure.
How did California tax titanium-nitride coating applied to used and new customer-owned cutting tools?
Used-tool coating was repair; new-tool coating was a sale whether the customer consumed or resold the tool, with retail-versus-resale treatment following the customer's use.
Could a biotechnology company buy fermentation nutrients and other inputs for resale when producing recombinant protein medicines with living cells?
Only inputs that physically contributed to the protein sold qualified for resale; process-only materials and the production cells themselves were taxable.
Who was the seller of sampled food at a paid public-television fundraiser when vendors donated products but station volunteers primarily served them?
The television organization was the seller because its volunteers primarily served the donated food. Vendor service could have produced a different seller.
Did a proposed stock-only operating-asset transfer trigger sales or use tax, and did the new legal entity need replacement exemption certificates from approximately 7,220 California customers?
No. The opinion treated the operating-asset transfer as nontaxable because the only consideration was first-issue stock, and it did not require replacement certificates solely because the seller…
Were play-by-mail turn fees nontaxable moderation services when players could submit moves without buying or using the provider's forms?
Yes, if forms were free, optional, and independent of rulebook and turn charges; rulebooks and any required or bundled forms remained taxable.
Were architects' design drawings and blueprints taxable, and how did California distinguish original design from drafting another person's specifications?
Original design and blueprints required by the commission were nontaxable services; later extra copies and drawings made solely from customer specifications were taxable.
Were reverse-engineering charges taxable when a firm disassembled an instrument and delivered vellum drawings, parts lists, and assembly instructions?
They were nontaxable if the drawings conveyed engineering information and no production contract existed beforehand; a prior manufacturing obligation changed the result.
Was an asset-sale transfer of master prewritten programs taxable when the buyer acquired copyrights for publication and distribution?
No. The buyer acquired copyright interests for third-party publication and distribution, and the seller's retained internal-use rights involved no reverse property transfer.
Did advertising brochures qualify when a publisher used its own printing or mailing divisions, and would separate corporate entities change the result?
No for the in-house arrangements: self-printing involved no sale, and delivery by an outside printer to the publisher's mailing division was delivery to the purchaser. Separate corporations could…
Were charges for a customized credit pre-screen service taxable when the firm delivered a magnetic tape listing candidates who met client-specific criteria?
No. The client bought customized evaluation and data extraction, not the tape; the firm consumed the magnetic tapes and other property used in the service.
Was bunker fuel exempt when a time-charter customer bought it for a vessel's California-departing voyage?
Staff counsel agreed with the hearing officer that the charterer bought customer-furnished fuel for its own obligation, outside the common-carrier exemption. The Board hearing was still pending.
Did the therapeutic Congleton Neutral Posture Chair qualify as exempt medicine?
No. California treated the chair as a taxable supportive apparatus or appliance despite its pain-reduction and recovery benefits.
Could a California aircraft purchase qualify when the buyer simultaneously leased it to a noncarrier that simultaneously subleased it to a common carrier?
Yes, on the stated assumptions. With no intervening use and a qualifying end-user common carrier, the simultaneous purchase, lease, and sublease fell within section 6366.1.
Who had to collect California use tax when a local playground consultant recommended an out-of-state supplier's equipment for a commission?
The out-of-state supplier. The consultant did not buy or resell the equipment, but its recommendations and commission made it the supplier's California sales agent under section 6203(b).
Was an optional support contract taxable when it provided telephone help and might supply updated software on tangible media?
For prewritten software, the entire charge was taxable if an update was actually transferred during the contract; telephone-only support with no update was not taxable.
Was sales or use tax due when a subsidiary distributed unencumbered fixed assets to its parent as a property dividend?
No, assuming the subsidiary received no consideration. Without payment or assumed debt, the property dividend was not a sale.
Under the historical rule, when could a lessor bring formerly out-of-state leased property into its California operations without use tax?
Outside-bought property had to stay out beyond 90 days; California-bought property reenter after six months; MTE was later expressly excluded.
Was an auctioneer's 10% buyer premium included in taxable gross receipts in addition to the winning bid?
Yes. The premium was part of what the buyer had to pay to obtain the goods, so a $100 bid produced $110 of taxable gross receipts.
How were fees treated when software agreements granted both internal-use rights and rights to copy and sublicense programs to third parties?
Fees for copying for sale or sales demonstrations were excluded; internal use, CPU testing, and other own-use rights were taxable and required allocation.
Was an auctioneer's 10% buyer's premium included in taxable gross receipts from the auction sale?
Yes. The buyer had to pay the bid plus the premium to obtain the goods, so both amounts were gross receipts of the auctioneer-retailer.
Did California tax replacement parts installed outside the state during periodic maintenance of aircraft leased to common carriers?
No. Integral parts installed outside California became part of the aircraft before it returned, so the lessor's out-of-state purchase was not subject to use tax.
Were vehicle transfers taxable when a subsidiary paid them as a dividend to its parent, which then contributed them to other subsidiaries?
No, assuming no corporation paid or received consideration and nobody assumed vehicle debt. Without consideration, neither transfer stage was a sale or purchase.
Did California use tax apply to spare parts stored here on standby and later used solely outside the state under optional maintenance contracts?
No for categories ultimately used solely outside California; standby storage and depreciation did not defeat section 6009.1. California-use parts remained taxable.
Did storing optional-maintenance spare parts in California create use tax when the parts were later used solely outside the state?
No. California standby storage was excluded when the parts were later used solely out of state, and claiming depreciation did not defeat that exclusion.
Who owed lease tax when financing assignments transferred rent and security interests but left lessor obligations behind?
The original lessor. All four supplied structures assigned rent plus security interests, and tax the finance company reported had to offset the lessor's liability.
Were fully wearable FM assistive listening systems treated as hearing aids for California sales tax?
Yes. The receiver, earbud, microphone, and transmitter system qualified as a hearing aid, so the licensed dispenser was the consumer and its customer receipts were not taxed.
When were touring-equipment rentals taxable in California, and what evidence controlled the historical district rate?
Tax applied for California periods/possession; carrier records, contracts and followed itineraries could prove outside periods or another district of use.
Could a gravel-pit owner become a construction subcontractor by having the prime contractor install the material it sold?
No. Without an obligation to the landowner for final installation, it was a retailer taxed on material-sale gross receipts. It was a consumer only on genuine furnish-and-install work.
Was microfilm sold to a law firm exempt merely because the firm used it while representing the federal FSLIC?
No. The law firm—not the FSLIC—bought and consumed the microfilm in its legal practice. Exemption required a direct documented federal sale or a genuine resale to the FSLIC before the firm used the…
Did donor-funded personalized books given free to hospitalized children and students count as taxable retail sales?
No. With no contractual duty to provide a book and no consideration received for each gift, the maker was the consumer and owed use tax on ex-tax materials used.
When could California excuse interest on a sales-and-use-tax liability?
Generally only through a statutory exception: qualifying disaster relief under section 6593 or reasonable reliance on the Board's written advice under section 6596.
Were wheelchair replacement parts and repair labor exempt when directed by a physician?
Qualifying replacement-part sales to the individual were exempt, and repair labor was not taxable; contractor status depended on pricing.
Did the needle-free Vitajet insulin injector qualify for exemption when sold by a nonpharmacist?
No. California classified Vitajet as an insulin syringe, but the historical exemption required a registered pharmacist to furnish it.
How long did a withdrawing service-station partner remain liable after the partners tried to end the business relationship?
Through May 3, 1986. Appeals found the partners initially allowed continued operations while negotiating a buyout, but later operations were the managing partner's alone.
Was a lump-sum charter of a 35-foot sailboat a taxable lease when the owner always remained aboard as the required skipper?
No. Because the owner retained possession and control as skipper, the customer bought transportation services rather than leasing the vessel.
Was an owner-skippered 35-foot sailboat charter a lease eligible for FRV reporting?
No under the stated assumption. Owner control made it a transportation service, not a lease; the live annotation says lease-receipt reporting was unavailable and purchase-price use tax was due.
Were separately sold advertising envelopes exempt when the envelope printer sent them to a mailing house but did not sell the enclosed printed messages?
No. The printer sold only envelopes, not envelopes with printed sales messages, and did not sell them to a person who inserted and sold the message together with the container.
Was a specially developed software version custom when existing versions could not operate on the customer's computer system?
Yes for the first customer, despite shared code or reserved relicensing rights. Development fees and royalties were also excluded when paid for third-party republication.
Was a noncustom software update taxable when copyright attached and the customer received it solely for republication with hardware sold to third parties?
No under the approved facts. Copyrighted updates transferred solely for third-party republication with the customer's hardware were excluded even if not custom software.
Was additional tax due on the untaxed remainder of a lump-sum installed telephone-system price?
No additional tax was due on the installer's construction contract after tax on materials and fixture cost. Tax on the buyer's later lease, financing sale, or option depended on the missing customer…
Were flat fees and royalties for customized operating systems taxable when customers reproduced the programs for sale or license to their own customers?
No if the customers were not end users and acquired the programs for reproduction and resale or licensing. The same fees were taxable for end use.
When did interest begin if chassis were not removed from California within the exemption's 75-day period?
Interest ran from the original tax due date for the sale's reporting period. The 75-day removal condition did not extend the payment deadline for a transaction that failed to qualify.
How did title clauses, separate material pricing, and contractor status change tax treatment across three Indian Housing Authority construction contracts?
Non-Indian contractors were retailers only with both pre-installation title transfer and separate material pricing; qualifying Indian contractors could receive reservation-delivered materials exempt.
Were investment diamonds exempt from California use tax after the buyer owned and stored them with an out-of-state trust company for more than 90 days?
Yes, under the historical 90-day rule. The hearing officer recommended removing that sale because the buyer owned the diamonds and stored them out of state for investment before California entry.…
Was the Save the Books campaign equivalent to a Friends of the Library organization for sales-tax purposes?
Yes. Its library-restoration fundraising objectives were close enough for section 6370 consumer treatment, so its merchandise-sale receipts were not taxable.
Did time spent repairing an accident-damaged car in Europe count as out-of-state use under California's historical 90-day rule?
Yes. Repairing the car was an exercise of ownership and therefore use, even after the owner returned to California. Because driving and repair kept the vehicle in out-of-state use for more than 90…
Did an unaffiliated California store create nexus by displaying an Oregon mail-order seller's catalogs for consumers?
Yes, under the 1987 opinion. The store promoted the catalog seller's products and was treated as its California representative.
Could staffing-agency workers doing art fabrication qualify as loaned employees, and when would the agency's charges avoid tax?
Yes, conditionally. The customer had to provide the workplace, tools, and materials and pay hourly; additional supervision or similar-employee tests also applied.
Did programs developed to test customer semiconductors on test machines qualify as custom computer programs?
Staff recommended yes. The testers evaluated parts but did not make or process a product, so the programs were custom programs used on computers.
