When did Shaklee Instant Protein Drink Mix become taxable after its label began saying to use it only as a food supplement?
California reclassified it as taxable prospectively on January 1, 1992; retail sales before that date remained nontaxable.
Was a charge for sending a photographic image through a remote electronic wire service subject to California sales tax?
No, under the letter's narrow historical definition. It treated a photographic-image transmission from premises other than the receiver's as no transfer of tangible personal property. The source…
Was a charge for sending a photograph through a remote electronic wire service taxable?
No. California said the remotely transmitted photographic image was not tangible personal property when sent from premises other than the receiver's.
Could an automobile broker claim a tax-paid resale deduction when a dealer charged tax on a vehicle bought for prompt resale?
Yes, if the broker resold the vehicle without disqualifying use. It remained responsible for tax on the customer sale and deducted its dealer purchase price.
Were printed real-estate publications exempt when the printer shipped them to the purchaser's parking lot for pickup and free distribution by an outside vendor?
No. Delivery to the purchaser's premises defeated the printed-sales-message exemption, even though an independent contractor immediately picked up the publications for free distribution.
How did California apply use tax when an out-of-state printer mailed promotional material from Pennsylvania or routed it through a California bindery, mailing house, or post office?
Mailing from Pennsylvania caused no California use tax because title and use occurred there. Routing pieces through California was a taxable use unless the printed-sales-message exemption applied.
Could a printer use a trucking partnership owned by its majority owners to make qualifying printed-message deliveries and pass through nontaxable freight charges?
Yes under the stated assumptions. The related carrier had to operate separately, be paid for transportation, and deliver directly to outside contractors or delivery companies rather than the purchaser.
When did California use tax apply to promotional pieces printed outside the state and mailed to recipients inside and outside California?
Mailing the pieces outside California put the customer’s use outside the state. Sending them first to a California bindery, mailing house, or post office created California use, subject to any…
Were advertiser payments taxable receipts when a publisher supplied maps to a chamber of commerce without direct chamber payment?
Yes. The publisher sold the maps to the chamber, and advertisers paid on the chamber's behalf, so those amounts were taxable gross receipts.
Were a graphic designer's client meetings and printer coordination taxable when included in selling a newsletter layout?
Yes. Tax applied to the total layout charge, including meetings and printer coordination; only type-composition output containing type alone was nontaxable, while charges attributable to pages with…
When were sales of injected Magnevist MRI contrast exempt as prescription medicine in California?
Magnevist qualified as medicine, but sales were exempt to doctors and hospitals under the stated conditions, not to labs or diagnostic centers lacking 24-hour admissions.
Could a tree nursery deduct special UPS packing and legally required inspection charges from taxable gross receipts?
No. Packing was taxable handling labor, and required inspection costs were nondeductible expenses because no statute excluded them.
Was a two-percent credit-card surcharge taxable when it reimbursed an electronics retailer for card-processing costs?
Yes. The flat surcharge was a taxable business cost included in gross receipts, not excludable interest tied to how long the buyer took to pay.
Did a county's 1990 purchase order for dump trucks qualify for protection from the July 15, 1991 tax-rate increase despite later delivery?
Yes, assuming no notice-only termination right. The purchase order accepted a fixed-price offer before the cutoff and stated the sales price plus tax reimbursement.
Were a graphic artist's monthly administrative-service fees taxable when the supervised projects produced finished artwork?
Partly. Fees connected with producing and selling finished artwork were taxable, while fees tied only to nontaxable services were not.
How did California tax a custom-software developer's production tools, copies, packaging, training, and feasibility studies?
The custom-program transfer was not a taxable sale, but the developer owed tax as consumer on production inputs; extra copies and packaging were taxable.
What ownership or control was required for corporations to satisfy California's unity-of-ownership test for a unitary combined report?
The same interests had to own or control more than 50% of the voting stock of every corporation in the proposed unitary group. Voting stock meant power to elect the board. Direct and indirect…
When taxable groceries were paid for with food stamps, cash, and manufacturer coupons, which amounts were subject to California sales tax?
Cash and manufacturer-coupon amounts were taxable; only the amount actually paid with food stamps was exempt, and food stamps applied first to taxable merchandise.
Were photo plots and drill tapes taxable when a manufacturer retained possession but its contracts transferred title before using them to make burn-in boards?
Yes. The audit record supported title transfer to the customers, making the plots and tapes separate sales in California even when the finished boards later shipped out of state.
Was a satellite sale taxable in California when the builder retained title and control until successful insertion into the prescribed orbit?
No on the stated assumptions. Title and control passed only after successful orbit insertion, so the sale occurred outside California regardless of where the satellite was above Earth.
Were large steel-frame buildings assembled onsite construction projects even when they rested by their own weight and could later be dismantled?
Yes. Their size, sectional onsite assembly, and inability to move as a unit made furnish-and-install contracts construction contracts whether anchored or resting by their own weight.
Were separately billed chemical-toilet cleaning charges excluded from taxable rent as optional services?
No. Separate invoices did not overcome oral contracts and actual practice showing cleaning was mandatory; the service charge stayed taxable rent.
Were separate charges taxable when a manufacturer optionally preassembled new steel stampings into sections to make jobsite installation easier?
Yes. Preassembling the stampings was taxable as a service forming part of the sale or as fabrication, not installation, even if optional and separately charged.
Was a 25% charge for manufacturing and delivering measurement equipment within five working days taxable?
Yes. The optional expedite service was part of the equipment sale and the 25% charge was included in taxable gross receipts.
Was Gold's Nutritionalysis 100% Pure Milk/Egg Protein Powder taxable when its label called it a protein drink supplement for muscle building?
Yes. It was a powdered drink mix expressly marketed as a protein supplement, so California excluded it from the food-product exemption.
Was treating customer-owned copper welding wire nontaxable repair when the vendor removed contamination, or taxable fabrication when it made new wire?
Heating the same wire to remove impurities and recondition it was nontaxable repair. Melting it into copper castings and drawing new wire was taxable fabrication.
Did section 6563 prevent California from issuing a new determination for a tax period that remained open after an earlier determination and hearing?
No. The memorandum treated section 6563 as authority that can extend the Board's ability to increase a determination, not as a restriction on an otherwise open period.
Were a printer's sales of advertising inserts exempt when the retail-business customer—not the printer—contracted with newspapers for insertion and distribution?
Inserts for sold newspapers could be supported by resale certificates; free-newspaper inserts became exempt October 2, 1991, and qualifying printed sales messages required proper carrier delivery.
How did California tax a stage-production company's design work, scenery, models, out-of-state projects, installation, and equipment rentals?
Transferred designs, models, scenery, platforms, and related production charges were generally taxable; qualifying out-of-state shipments and installation labor could be excluded, and actual…
When could a DME company sell qualifying medicines tax-free to nursing homes and long-term-care facilities?
The memorandum said qualifying health facilities could use exemption certificates, while mixed-use buyers could use resale certificates and pay use tax on taxable items withdrawn for their own use.
Could a contractor deduct preliminary design work from the taxable price of brochures written, designed, and printed for California?
No. The entire brochure price was taxable because the contractor used the finished art to produce its own printed product, did not furnish finished art to the client, and showed no qualifying…
How did California tax a satellite information subscription that included company-owned receiving equipment, startup fees, and monthly charges?
Satellite transmissions were nontaxable services, but the equipment appeared leased; tax could be measured by timely paid equipment cost or by attributable rentals depending on acquisition and…
Were subscription charges for satellite data transmissions and the receiver equipment both subject to California tax?
Transmission charges were not taxable; the receiver was apparently leased, with tax on cost after a valid election or otherwise on attributable rent.
Did allocating overhead costs to qualifying federal contracts make the overhead purchases nontaxable when the taxpayer's own contract lacked a title-passage clause?
No. Cost allocation and similar accounting treatment did not replace a title-passage clause; overhead tied to contracts lacking the required clause remained taxable.
Were sales to Amtrak exempt from California sales and use tax even though Amtrak was not a United States instrumentality?
Yes. The 1991 memorandum said federal law exempted Amtrak from state sales and use taxes, so California treated sales to Amtrak as exempt under Revenue and Taxation Code section 6352.
Was the absorbable Collastat collagen sponge exempt as prescription medicine in California?
No. California treated Collastat as a taxable temporary biological dressing because it stopped bleeding and supported clot formation like a traditional bandage or dressing.
Was a temporary bovine-collagen corneal shield exempt as prescription medicine in California?
No. California treated the shield as a taxable temporary biological dressing because it protected and hydrated the cornea while the tissue healed.
Did one subscription installment paid before July 15, 1991 grandfather the entire magazine subscription after California repealed its general exemption?
Yes. A partial payment to the retailer before July 15, 1991 made the entire subscription 'paid for' before that date for section 6362.3's historical grandfather clause.
Could a contractor buy 35mm film for resale when DMV employees exposed it and the contractor used it to produce driver's licenses?
No. The recommendation treated the contractor as consuming the film because it did not become part of a license, the contract retained title in the contractor, and DMV paid per license rather than…
Were engineering, installation, and reassembly charges taxable when an Oregon manufacturer sold a custom oven fixture to a California customer?
Engineering and the disputed reassembly portion were taxable use-tax measure, while installation labor was not; the seller had to collect the tax and oral advice gave no relief.
Could California reconsider a denied refund claim after the taxpayer let the 90-day deadline for filing a refund lawsuit expire?
No. The memorandum concluded that the Board lost jurisdiction when the taxpayer did not sue within 90 days after mailing of the denial notice.
Were custom-oven engineering and reassembly charges included in California's use-tax measure?
Yes. Design engineering was part of the oven sale, and reassembly remained taxable because it was not separately stated and the buyer was not shown free to hire someone else.
Was a catering house the propane retailer when it collected drivers' payments and retained ten cents per gallon?
No. The propane company delivered and controlled the fuel, set the price, and billed each truck. The catering house only collected the fixed charge and retained a service fee, so the recommendation…
Which fees under the described software sublicensing program were taxable?
Participation, sublicense, royalty, porting-service, certification, and subcontract support fees were excluded; porting-kit and direct end-user support fees were taxable.
Did monthly real-estate flyers qualify as printed sales messages when they contained articles and the printer shipped them by UPS directly to customers?
No. The submitted flyers did not principally promote goods or services, and direct delivery to the customers independently defeated the printed-sales-message exemption.
Was a photographer's full charge taxable when only about 15 of roughly 100 shoe-catalog photographs were ultimately used?
Yes. The entire charge was taxable gross receipts even though only 15 of approximately 100 photographs appeared in two yearly shoe catalogs and the rest were light-placement or test shots. Section…
Was a large wrought-iron gate fabricated offsite and installed on concrete-embedded posts a material or a fixture?
It was material. The Board treated the 7-foot-6-inch by 20-foot-1¼-inch gate like fencing or doors despite offsite fabrication and unit installation.
Did sharing 20% of school vending receipts make the operator and school partners so the food sales were exempt?
No. The operator owned, stocked, serviced, insured, and bore the risk on the machines; the school mainly supplied space and utilities. Its 20% share was percentage rent, not partnership profit, so…
Were skid-mounted backup generators installed at a federal launch site fixtures or machinery and equipment for California sales-tax purposes?
They were fixtures. Their removability aided maintenance, but they were integral and necessary to launch-site power, so the seller's sale to the prime contractor was taxable.
Were synchronized slide-and-audio modules taxable in full, and did the producer avoid use tax on photographs by claiming pre-use title passage or client agency?
The full module receipts were taxable, and use tax applied because the producer failed to prove either client agency or a sale of the photographs before reproduction.
Was screen-printing a customer's used T-shirt taxable fabrication or repair work?
It was repair work. Tax applied to separately charged materials, or to their fair retail value when they exceeded ten percent of the total charge; the remaining repair charge was nontaxable.
Was an asset transfer to a wholly owned subsidiary taxable when the parent received cash days later through a joint-venture financing arrangement?
Yes under this recommendation. Staff treated the linked cash-back financing as consideration, not a dividend. The source records $225,379.25 moving through the entities but later calls corrected…
Were dehydrated muesli, pasta, chili, and soup meal replacements exempt even though they contained much powder and were designed to reduce calories?
Generally yes. Counsel treated those product categories as traditionally accepted foods, but no labels were supplied, so the letter did not rule on any specific item.
Were custom directories, large metal consoles, and dimensional letters fixtures when factory-built and installed with substantial onsite work?
Yes. They retained their identities as sign accessories after installation; architectural integration, size, electrical work, and labor to position or attach them did not make them materials.
When were custom architectural signs materials rather than fixtures under a manufacturer's lump-sum installation contracts?
Factory-built signs that remained identifiable were fixtures. Materials treatment required actual piece-by-piece jobsite construction or a qualifying structure whose components lost their identity.
Were parking and traffic-control signs materials merely because they were installed on posts, concrete bases, garages, or buildings?
No. Prefabricated signs that retained their identity were fixtures; material treatment depended on building the sign piece by piece at the site or creating a qualifying large structure.
Was Stretch Island Fruit Leather taxable as candy, confectionery, or snack food under the California rules applied in 1991?
No. California treated the compressed dried-fruit product as nontaxable because it was neither candy or confectionery nor snack food.
Could a UPS charge printed on the delivered package separately state freight when the wine invoice used a lump-sum price?
Yes. California treated the UPS stamp like postage, allowing exclusion of actual freight, but did not allow overcharges on some sales to offset undercharges on others.
Did California use tax apply when a cruise company bought an out-of-state vessel, chartered it back for 91 days of out-of-state use, and then brought it here?
No under the regulation then in effect. More than 90 days of out-of-state use rebutted the presumption that the vessel had been purchased for California use.
Did prescribed blood-glucose monitoring equipment and test supplies qualify as medicine in California?
The historical opinions said no, while exempting patient-applied glucose and skin cleansers; a later annotation note identifies specified current treatment for strips and lancets.
