Were charges for producing personalized letters by laser imaging taxable in California?
Yes. California treated laser imaging as taxable printing for a consumer, even if the customer supplied the paper or other materials.
Were admarking charges for outer envelopes and business reply cards taxable in California?
Outer-envelope addressing was a nontaxable mailing service, but printing an address on a business reply card was taxable.
Were Ensilo-Mix, Silo-Guard, and Silage Mate exempt when added to silage for qualifying animals?
Yes. Because portions remained on the silage when livestock consumed it, the products were feed ingredients and were exempt when used in qualifying animal feed.
Did an attendant-operated Lumex three-position recliner qualify as an exempt wheelchair?
No. California taxed it because the patient could not operate it for meaningful mobility and the wheels mainly helped attendants place the chair.
Were dialyzer-reprocessing and dialysis data-management systems exempt related supplies?
No. California treated both systems as taxable peripherals because a dialysis machine could operate without them and neither was applied to the patient's body.
Did dialysis-machine accessories for filter reuse and data management qualify as medicine?
No. The memorandum treated both systems as taxable peripherals because dialysis could continue by replacing the used filter, and neither system was a substance or preparation applied to the patient.
Did sales tax apply when the Board charged direct cost for public-record copies or created a typed transcript in a different form at a requester's option?
Required copies of existing public records were not taxable, but a discretionary typed transcript or guide created in a new form was taxable.
How did California tax temporary publication rights when a stock photographer delivered a physical photograph that the client later returned?
It was a lease of the physical photograph, not only an intangible-right license. Rentals could be nontaxable when a tax-paid developed photo or lab-made print was leased in substantially the same…
How did California tax temporary stock-photo publication rights when the photographer delivered a print or transparency?
It was a photograph lease. A tax-paid lab print could be leased tax-free, while a transparency made from the photographer's film had taxable rent.
Did state-university, community-college, or private-college libraries qualify for California's public-library copy-machine rule?
No. They were not library districts, county libraries, or municipal libraries formed under the cited Education Code procedures. Their coin-operated copy sales therefore remained retailer…
Did a 60-mile trip through offshore waters qualify when all fishing occurred within three miles of a California island?
No. The voyage was operational use outside the mainland limit, but all actual fishing occurred in California territorial waters surrounding the island. Travel distance and time could not substitute…
How was tax measured when a buyer traded California land worth $8,000 for a pickup truck worth less?
The $8,000 land value was the measure. A dealer owed sales tax based on property received; in a private sale, the buyer owed use tax based on property paid.
Did a Navy shipbuilding clause vesting title to materials and equipment 'for the vessel' also pass title to direct consumable supplies before contractor use?
Generally no. The clause covered vessel components and function-enabling property, not supplies merely used on the job, although some testing items required factual review.
Were site-license fees taxable when they let existing software buyers make extra copies, and who owed tax on copies sold to members?
Yes. Site-license fees were additional receipts from the original software sale; customers reselling duplicate disks were retailers taxable on their sales.
Did a commercial sightseeing hot-air balloon qualify as aircraft used by a common carrier under California's aircraft exemption?
No. Its burner controlled altitude, but wind—not a powered navigation unit—controlled horizontal movement, so the balloon was not aircraft under section 6274.
Was a prescribed Medi Lift Chair exempt as a wheelchair or other mobility aid?
No. California taxed the lift chair because it only helped a person sit or stand and did not assist movement after the person left the chair.
Could a cement maker treat the flyash portion of kiln coal as a resold ingredient even though the coal was also burned for heat?
Yes, for the verified flyash value. The flyash supplied required cement ingredients without intervening use, while other additives received separate primary-purpose treatment.
Did the four-times-monthly Official Airline Guide qualify as a periodical even though it consisted mostly of flight data?
Yes under the 1986 analysis. Its frequency and comprehensive, nonproprietary flight data made it a travel-industry reference periodical.
Did the four-times-monthly Official Airline Guide qualify as a periodical even though it consisted largely of comprehensive flight and fare data?
Yes under the 1986 analysis. Its comprehensive flight data and frequency qualified; other guides required the same facts.
Could a contractor and conforming subcontractors buy materials and fixtures for resale when building reservation homes for an Indian Housing Authority?
Yes. Separate material pricing and pre-installation title passage made them retailers; they needed permits, could issue resale certificates, and made exempt reservation sales.
Could a contractor buy materials and fixtures ex-tax for homes sold to an Indian housing authority on a reservation?
Yes, under the described contracts. Pre-installation title transfer and a separately stated materials price made the contractor a retailer, and its reservation sales to the housing authority were exempt.
Were disposable plastic clips used for temporary surgical bleeding control exempt sutures?
No. California taxed the clips because they temporarily controlled bleeding at incision edges rather than surgically uniting tissue as sutures do.
Was providing trained animals for rides, performances, or exhibitions a taxable lease when the owner kept custody and control?
No. When the owner/handler kept possession and control, customers bought the combined trainer-and-animal service rather than leasing the animal.
Did 'educational purposes' under Regulation 1527 cover only master recordings made for schools and colleges?
No. California read the term broadly to include master tapes and records made for general instruction, education, and training presentations outside formal educational institutions.
Did California's continuing tax levy reach money deposited into a bank account after the bank received the notice?
No. Staff read the 1984 amendment to reach only funds in the deposit account when the bank received the notice, unlike recurring contract payments covered during the levy period.
Was a utility's sale and leaseback of consumable nuclear fuel a taxable lease or an exempt financing transaction?
It was exempt financing. The utility sold completed fuel, repaid the advance and finance charges, and recovered remaining title for no extra price.
Who had to prove a pharmacy's prescription sales were exempt, and could the Board inspect prescription records?
The pharmacist bore the exemption burden. If satisfactory proof was not supplied, the Board could determine tax from available information, including estimated street value, and inspect prescription…
Was an aircraft manufacturer's no-charge supply of temporary engines to a common-carrier customer an exempt lease while contracted engines were delayed?
No. With no consideration, it was an accommodation loan and taxable use by the manufacturer, measured by fair rental value. The aircraft exemptions did not cover the engines.
Was a deburring service's furniture-and-fixture sale exempt when taxable material sales were under 1 percent of receipts?
Mostly yes, under stated assumptions. Property used exclusively in polishing for manufacturers was exempt, while property used in the small taxable materials-selling activity remained taxable.
Which cultured-marble products were materials or fixtures after California's later corrections?
Bathtub shells and vanity tops with molded basins were ultimately materials; drop-in bowls and one-piece shower stalls remained fixtures, subject to installation facts.
Could California demand separate maximum security deposits from three limited partnerships sharing the same general partner?
Yes. Staff treated each partnership as a separate statutory person and permit holder, regardless of the common general partner or how the permits displayed his name.
Did placing commissioned catalog-order centers in California public libraries make the participating mail-order firms collect use tax?
Yes under the historical analysis. The center operator displayed catalogs, collected and forwarded universal order forms, and earned a commission, making it each retailer's California sales agent.
Did informal California office use by a nonprofit's journal editor and western division require use-tax collection on out-of-state mail-order sales?
Yes under the historical analysis. The editor and division used California offices for association work, creating a place of business under section 6203(a) even without formal leases.
Were posters, vinyl carry bags, and records inserted into and distributed with an exempt periodical all exempt component parts?
No. Printed paper posters were exempt components, but vinyl bags and records were taxable premiums even if attached; tax was measured by their cost absent evidence of a higher receipt.
Was a bill of sale followed by a conditional resale a taxable property sale when the documents secured what the parties treated as a loan?
No, under the stated assumptions. California treated the documents as a secured money loan rather than a sale of tangible personal property.
Were Lossing Back Trac and Neck Trac traction devices exempt orthotic devices?
No. California taxed the traction devices because they were supported from a stationary object, did not permit ambulatory movement, and were not fully worn on the user.
Did a catering, restaurant, and gourmet-shop business at one location calculate the 80/80 rule by department, and were its bulk take-home foods taxable?
The departments were combined as one location, so both 80% tests were met. But bulk and whole-item foods not suitable for on-premises consumption remained exempt.
Did free possession of an analyzer and computer become a lease when the customer promised to buy a minimum quantity of test packs?
Yes. The purchase commitment was consideration for using the equipment, creating a lease rather than a reward-free loan for use.
Was an analyzer and computer a free loan when the customer promised to buy at least 50 test packs daily for 180 days?
No. The 50-pack daily promise was reward for equipment use, creating an equipment lease and test-pack sales, not a reward-free loan.
When was a public agency taxable on repeated sales of temporary buildings removed from acquired land?
Three or more substantial sales within 12 months made the agency a person in the business of selling, but a later source note limits taxability to cases where the seller severs the building from the land.
Were meals and beverages taxable aboard a Lake Tahoe cruise that began and ended in Nevada, traveled mainly through California waters, and never docked in California?
No, under the memorandum. The vessel was a carrier and the continuous Nevada-to-Nevada cruise was treated as a trans-state trip, exempting beverage and meal sales despite travel through California waters.
Could oil producers buy kerosene distillate for resale when they first injected it into wells for stimulation and later recovered it in crude oil?
Yes, to the extent recovered in the crude. Its primary purpose was meeting the buyer's viscosity specification as a required diluent, despite also aiding well stimulation.
Could an electric three-wheel scooter qualify for California's wheelchair exemption?
Yes. California treated the scooter as an exempt wheelchair when sold or rented to an individual for personal use as directed by a physician.
Were per-item subsidies paid by a site customer part of a vending operator's taxable gross receipts?
Yes. Each subsidy amount was tied to the type and number of beverages sold and therefore traceable to particular retail sales. The customer payments joined the coins paid at the machine in the…
Could durable aluminum plates be special printing aids even when obsolete content meant they were never reused?
Yes. Their material allowed reuse, so the plates qualified even though the printed matter became obsolete and the plates were not actually reused.
Were charges for converting customer programs and data to a different computer system taxable when the translated material was returned on customer media?
Application-program translation was nontaxable custom programming, but converting file records or data was taxable whether performed manually or mechanically.
Were charges to translate application programs and data files for different computer equipment taxable?
Application-program translation was excluded as a custom modification; translating file records or data was taxable physical-form conversion, regardless of method.
Could California tax audit staff inspect and record patient and medication information from pharmacy prescriptions?
Yes, under the 1985 opinion. It treated the Board as a duly constituted authority and a person authorized by law to inspect the records for an exemption audit. The pharmacy had to provide the…
What happened when a seller's F.O.B. factory quotation conflicted with the buyer's F.O.B. jobsite purchase order for common-carrier delivery?
The conflicting F.O.B. terms dropped out. Commercial Code gap-fillers created a shipment contract, title passed when the seller gave the goods to the carrier, and transportation was excluded.
What general guidance did California give a hospital for distinguishing exempt medicines from taxable supplies?
California could not classify abbreviated entries definitively, but supplied historical medicine rules and extensive general lists of taxable and exempt hospital items.
When does breeding a mare held for resale become taxable use rather than demonstration of fertility?
The proposed breeding-and-resale plan was not taxable on its stated facts. The Board's guidelines treated two or more foals while owned, capitalization and depreciation, or retention beyond two full…
Where did California place tax in a chain of three or more leases when only the final customer used the property?
At the final consumer lease. Earlier no-use leases were for resale; collection targeted the last sublessor, then only the consumer if needed.
Did a California retailer owe use tax on out-of-state-printed catalogues delivered door to door by independent companies?
Yes. The delivery companies acted as the retailer's agents, and the retailer transferred title to recipients after the interstate shipment ended in California.
Did the exempt value of disability-related vehicle modifications carry over when a used modified vehicle was sold to another qualifying disabled buyer?
Yes. The modification portion remained exempt, but the buyer registering the vehicle had to prove its value and qualify under the special-parking standard.
When did a mare bought under a resale certificate stop being held for resale and become subject to use tax as breeding property?
When the second foal was born. Until then, documented sales efforts supported resale intent; afterward, the mare was treated as held for breeding.
Was a hospital's no-cost medical instrument a free loan when it required monthly catheter purchases and an early-return charge?
No. The monthly catheter-purchase promise and $475 early-return obligation supplied consideration, making Plan B a lease.
Could a manufacturer avoid California sales tax and use-tax collection on customer equipment made out of state, stored here, and later sent to offshore wellsites?
Yes, if the sales contract—not a unilateral notice—passed title outside California and the parties' records remained consistent. The seller also needed a timely, signed, good-faith certificate…
Were listed growth-promoting and disease-preventing ingredients taxable when incorporated into qualifying animal feed?
No, under the stated assumptions. California allowed vitamins, minerals, drugs, and medicines to be bought tax-free when incorporated into exempt feed.
Who was the retailer when PTAs acted as agents for a book seller at school book fairs?
The book seller. Because the PTAs merely acted as its agents, the seller's retail price to students was taxable and section 6370 did not treat the PTAs as sellers-consumers.
Did recycled lubricant oil sold as substitute industrial fuel qualify for the waste-by-product exemption?
Yes, if evidence showed the oil was part of the municipal waste stream and the customer used it as industrial fuel in place of oil, natural gas, or coal. California required factual support before…
