Who was the retailer responsible for collecting California use tax when a society hired a list manager to promote mailing-list rentals?
Counsel treated the society as the lessor and collecting retailer; the manager was its agent despite retaining part of the rental price.
Did a hospital sell disposable central-supply items to patients merely because it separately itemized them on patient bills?
Not when hospital staff used the items to provide professional services and title or possession never passed to patients. Staff recommended a fact-specific reaudit.
When did separately billed hospital central-supply items remain hospital-consumed property rather than retail sales to patients?
Treatment depended on actual use and transfer. Staff-used items could be self-consumed, while personal items or property given to patients were retail sales.
How did California tax public educational seminars that included lunch and course materials, and optional training on separately sold software?
Significant classroom instruction was nontaxable except for lunch, but a short mandatory lunch speech was fully taxable; optional software training was nontaxable.
Was an HMO brochure inviting prospective members to enroll, explaining benefits, and listing participating physicians a printed sales message?
Yes, when published and distributed to prospective members to explain enrollment benefits and promote the HMO's services; qualifying delivery could support an exemption certificate.
How did California apply sales and use tax to reupholstery, carpeting, linoleum, area rugs, delivery, and other interior-decorating charges?
The opinion separated taxable materials and fabrication from nontaxable installation and delivery, with lump-sum contractor rules depending on who consumed the materials.
Did the described postoperative silicone drains and reservoir qualify for California's surgical-opening supply exemption?
Yes, on the stated assumption that bodily fluids drained into the reservoir. California treated the items as qualifying appliances and related supplies.
Were Meadox cardiovascular knits, felts, meshes, pledgets, and fabrics exempt prosthetic devices in California?
Yes, when in fact permanently implanted to repair, reinforce, or assist the heart or blood vessels and sold or furnished under the required conditions.
Could an Oklahoma corporation buy motorcycles for resale, customize them in California and export them to foreign buyers before functional use?
Yes. Customization was not taxable use before resale, but a dealer could reject a resale certificate and collect sales-tax reimbursement.
Did a subcontract clause vesting title in the government and/or buyer clearly pass overhead materials to the United States before the seller used them?
No. Its mixed government, buyer, and seller references were ambiguous and did not show the clear pre-use federal title intent found in FAR 52.232-16(d).
Were television research reports nontaxable compilation services or taxable information products when delivered on tangible media in California?
Custom compilation could be a nontaxable service, but standardized specialty products, industry data, programs, and printed local surveys were taxable tangible property.
When were television research reports nontaxable compiling services rather than taxable information products delivered on tangible media?
Custom compilation could be a service if the contract price covered that work; standard reports, software, and post-repeal printed local surveys were taxable.
Were automobile-insurance quote reports taxable when each report depended on a customer's drivers, vehicles, records, uses, and desired coverage?
The first truly custom report was a nontaxable service; separately charged extra copies were taxable unless the contract required mailing them out of state.
Did printed-message exemption apply when the seller delivered publications to the purchaser's parking lot for same-day pickup by distributors?
No. Delivery to the purchaser defeated the exemption regardless of same-day redistribution; the seller needed to deliver to the distributor with common-carrier involvement.
Was a political-campaign consultant merely its client's purchasing agent, and were campaign brochures exempt printed sales messages?
No. Markups and nonseparate billing defeated agent treatment, campaign literature was excluded from printed-message exemption, and brochures and artwork were taxable retail sales.
Was a 60-month equipment contract a sale from the start when the customer could return the property after month 54?
No. It was lease through month 54; continuing or missing return notice triggered title and sale treatment for six remaining payments.
How did California tax data entry delivered on magnetic media, by modem, or as an address list?
Media delivery was taxable, including related programming; modem-only delivery was not. One original address list was excluded, but multiple copies or added media were taxable.
Did a political-campaign consultant buy brochures as its candidate's agent, and were campaign brochures exempt printed sales messages?
No. Markups and failure to separately invoice supplier reimbursement defeated agent treatment, making the consultant a taxable retailer of brochures and artwork; campaign literature was also…
Were database input and listing-insertion fees taxable when an outside vendor also printed and sold multiple-listing-service books?
Optional database input services were nontaxable if not required with the books, but any credit against the book price tied to buying the service joined taxable book receipts.
Were database input and insertion fees taxable when a vendor also printed multiple listing service books?
Not if the database service was entirely optional and not required with the books. A credit against book price for buying the service remained taxable book receipts.
Did the low-emission exemption cover a used vehicle that a retrofit company converted and then sold?
No. The former exemption covered new-vehicle incremental cost and retrofit devices, not the retail price of a used vehicle converted by its seller.
When did title and use-tax liability arise for installed equipment if the contract did not state a title-passage date and final payment came later?
When delivery was complete and the equipment was operational. The buyer's later acceptance or final payment did not postpone title under the source's section 2401 analysis.
Could a school parents' organization be treated as the consumer of donated items sold at its annual auction?
Yes, if it was equivalent to a PTA, operated with school authorization, and used profits exclusively for its purposes; donation of the items did not change that result.
Were a gliderport's gliders and tow planes exempt aircraft used as common carriers when customers paid for glider rides?
No. Unpowered gliders were not aircraft under the cited definition, and the tow planes moved the operator's own gliders rather than carrying persons or property for hire.
Was separately stated conference-center room rent included in taxable meal receipts when meals were optional and separately charged?
No, assuming customers paid the same room rate without meals. The rental served conference purposes beyond meal service, while the separately sold meals remained taxable.
When were sales of wheelchairs, crutches, quad canes, and walkers exempt in California?
They were exempt when sold to an individual as directed by a licensed physician, but taxable when sold for a medical facility's own patient use.
What wear and implantation conditions did California apply to prosthetic and orthotic devices?
The devices had to be fully worn on the patient, and implanted devices had to remain long-term; bed-attached or temporarily implanted surgical devices did not qualify.
Which diabetes products did California include in the insulin and insulin-syringe exemption?
The opinion covered insulin and qualifying insulin syringes furnished by a pharmacist under physician direction, but not glucose monitors, test strips, or other syringes.
How did California tax a high school's regular snack bar, student-club game concessions, and vending-machine rebate?
The regular snack bar's sales were taxable; qualifying club concessions at basketball games were not. The vending operator, not the school, owed tax under the stated arrangement.
Were twice-monthly pharmacy drug-price updates taxable when mostly identical database extracts were mass-produced on diskettes for hundreds of customers?
Yes. The superseding decision treated the identical diskettes as taxable produced property, not research services or software maintenance, and denied adjustment.
Were one-time, request-specific pre-employment background reports taxable, and what happened with fax delivery or later extra copies?
Unique researched reports were nontaxable services, and faxed information was nontaxable; later extra physical copies were taxable and triggered seller-permit duties.
Was an aircraft owner's transfer of a tax-paid plane to a revocable grantor trust subject to California use tax?
Not if it was a true donation with no consideration. Use tax applied to consideration provided by the trust, such as assuming the aircraft loan or paying it from trust funds.
Were massive concrete batch plants taxable personal property when sold in place on leased land with no immediate removal planned?
Yes. The leases kept the plants as lessee property and required their removal at lease end, so the agreements prevented real-property classification despite physical affixation. The staff…
Were computer-aided drafting output and charges for modifying a customer's existing electronic drawing files taxable?
Yes. Clients sought the special-order drawing output, and keyboard changes to customer-furnished disks were taxable physical modification or information recording.
Was a charge to edit a customer's existing drawing file taxable when the same electronic medium was returned?
Yes. Keying additions and deletions physically modified customer-furnished tangible media, so the separately billed editing charge was taxable.
Could a motion-picture producer buy blank master tapes and production materials for resale when it later licensed the completed masters to foreign distributors?
No. A motion-picture license or lease was excluded from sale treatment, so the producer consumed the ex-tax tapes and materials in California and owed use tax despite later foreign shipment.
Which market studies were nontaxable commissioned services, and which general, local-market, software, or industry products were taxable?
Advance-commissioned studies for a particular station or advertiser were nontaxable; speculative local surveys and general products were taxable on tangible media.
Did shipping donated resale inventory from California to out-of-state charities avoid California use tax?
No. The gifts were completed when delivered in California to the donees or their carriers, making the donor's withdrawal and donation a taxable use.
Did cash-register tapes carrying local-business ads and coupons qualify as printed sales messages when supplied free to stores and shoppers?
No. California treated cash-register tapes as specifically excluded; the regulatory exception for principally promotional content applied only to directories.
Was an honor-system candy box a vending machine eligible for California's low-price or nonprofit vending rules?
No. The box was only a container: it did not mechanically respond to payment by releasing goods. The customer deposited money and manually selected candy, so vending-machine provisions for…
Were company dining-room meals taxable sales when executives paid regular prices by personal credit card and were later reimbursed by their employer?
Yes. The executives personally bought the meals at regular prices, and later expense reimbursement neither converted the sales into intracompany transfers nor reduced the price.
How did California tax real-estate flyers, door-to-door delivery, office support, statistical studies, and other property sold by a service organization?
Flyers were retail property but qualified as exempt printed sales messages when properly mailed; property sales stayed taxable, while property-free support services were not.
Did California-only flights for aircraft service and maintenance destroy an interstate-commerce use-tax exemption?
No, if the flights’ sole purpose was to take the aircraft from San Jose to Long Beach for service and maintenance. The opinion left undefined “glitch type” work unresolved beyond that assumption.
Did crew-only flights within California to take an interstate-commerce aircraft to a maintenance facility break its use-tax exemption?
No, if their sole purpose was transporting the aircraft for service and maintenance. The answer relied on the aircraft otherwise remaining continuously in interstate commerce.
Could computer roughs qualify as preliminary art, and was a printed artwork output a nontaxable custom program?
Computer roughs could qualify when separate concepts were retained on one disk and the selected design was recreated on another with proper records; a transferred printout was taxable artwork, not a…
Were Optifast 70 and Optifast 800 exempt when furnished through the described medically supervised obesity program?
Yes. Although they did not meet the complete-dietary-food calorie test, California treated them as prescription medicines when physicians furnished them in the supervised program.
Were Optifast 70 and Optifast 800 exempt even though their 420- and 800-calorie daily regimens did not meet the 900-calorie complete-dietary-food example?
Yes, but as prescription medicines—not complete dietary foods—because physicians furnished them by prescription in a supervised obesity-treatment program.
Which federal contract clauses could pass title to contractor-acquired property to the United States before the contractor used it?
It depended on contract type, property type, execution date, and the actual FAR or predecessor clause. Progress-payment and government-property clauses controlled many items, with special rules for…
Were later component parts exempt because a tugboat's original purchase qualified through first-year interstate use?
Not automatically. Each component-part purchase was tested by the tugboat's principal use during the following 12 months. Parts were taxable if the vessel was then principally performing nonexempt…
Were inbound special-order shipping charges and fees for cutting board or paper into smaller pieces taxable?
Yes. Inbound shipping was a nondeductible expense, while cutting was taxable sale labor before transfer or a separate fabrication sale afterward.
Could pallets be taxable returnable containers without a deposit or title-retention clause?
Yes. California generally treated pallets as returnable when more than half were returned, even without a deposit or retained-title language.
How were canned software, training, modem work, maintenance, installation, freight, expenses, and warranties taxed?
Treatment varied: canned software and updates were taxable; standalone training and modem delivery were excluded; installation, freight, and warranties depended on facts.
When were used vehicles sold through the General Services Administration subject to California use tax?
Public sales of federal motor-pool vehicles under former 40 U.S.C. section 484(c) were taxable surplus-property sales. By contrast, similar-property exchange or sale transactions under former…
Were a lessor's ventilator rentals to hospitals nontaxable resales or exempt medical-oxygen-system rentals?
No. The hospitals consumed the ventilators in providing care, and the individual-use oxygen-system exemption did not apply to rentals made to hospitals.
Were ventilators rented to hospitals treated as resold to patients or exempt medical oxygen delivery systems?
No. The hospitals used the ventilators to provide medical services, and the patient-use exemption did not cover equipment rented to a hospital.
Did master-record treatment cover leased syndicated-program tapes used directly in radio broadcasts rather than to make copies?
Yes. California said the partial treatment included tapes and records actually used in broadcasting syndicated radio programs.
Were parts used by a California shop to repair a cracked boat taxable when the Wisconsin manufacturer covered the work under the original warranty?
No if the warranty was mandatory. The repair-shop and manufacturer part transfers were for resale; an optional warranty would instead make the manufacturer the taxable consumer.
When were National Geographic subscriptions taxable during California's 1991 newspaper and periodical exemption changes?
Generally taxable from July 15 through October 31, 1991, then exempt again from November 1 because the nonprofit distributed it for membership fees.
Did Bankruptcy Code section 1146(c) exempt court-ordered vehicle transfers from California sales and use tax?
No. The memorandum concluded that California sales and use taxes were imposed on sales or use, not on transfer instruments as stamp or similar taxes.
Who owed tax on repair parts used under mandatory maintenance terms when the lease was not a continuing sale?
The lessor was the consumer of the leased property and its repair parts, so sales or use tax applied when the lessor purchased those parts.
