Did the Holocaust Memorial Council's exemption also cover purchases, hotels, meals, or car rentals first paid by its employees and later reimbursed?
Generally no. Direct Council purchases were exempt, but an employee's full payment followed by reimbursement remained taxable. Only narrowly documented agency purchases—such as a federal contract or…
Were laser-show charges nontaxable performance services or taxable equipment leases when the provider supplied or withheld an operator?
Operator-controlled shows were nontaxable services; leaving equipment with the client created a lease whose tax treatment depended on tax paid at purchase.
Which parts of an implantable defibrillator system qualified as exempt medicine?
The implanted defibrillator and implanted leads were exempt; the external programmer and high-voltage surgical stimulator were taxable devices.
Could a corporation that had existed in good standing for years still be a commencing corporation if it had never issued stock or conducted business?
Yes on the presented facts. Prior years of existence did not disqualify the unused shell because it had never issued stock; recordation with the Secretary of State and Franchise Tax Board alone was…
Were charges to maintain, update, reformat, and custom-modify a State Library database taxable?
No for the identified contract. Database processing and separately stated custom modifications were services, though sold lists and training guides remained taxable.
Was camera-ready art taxable when the related newsletter printing qualified for the historical periodical exemption?
Yes when sold or delivered for the client's benefit. Exempt newsletter printing did not exempt camera-ready art, although art retained solely as the seller's aid was consumed.
Does separately billing a customer for molds, dies, or special tooling prove that the manufacturer sold the tooling?
No. Contractual title terms, possession, risk of loss, and other ownership benefits control; a separate tooling charge can be only a pricing method.
Could an aircraft lessor claim the common-carrier exemption after the aircraft's first years were private leases?
No. The first 12 months from first operational use were private leases, so later common-carrier leasing did not qualify and FRV reporting continued.
Could an aircraft lessor obtain a refund for later common-carrier lease years after the aircraft's first three years were private leasing?
No. The principal-use test was fixed by the first 12 months after purchase, which were non-common-carrier use. Later carrier leasing did not restart the test.
Could video lessors buy tamper-guard and information labels for resale with leased cassettes?
Yes, when the labels were attached before qualifying leases and the cassettes had no prior use. Missing seller permits made proof harder, not automatically taxable.
What treatment did a 1989 internal memorandum propose for on-site meals sold to tenants of qualifying low-income housing?
It proposed treating the meals as exempt under Regulation 1570 and treating welfare exemption for 80.1% of the units as substantial compliance.
Was a $300 return-shipping charge taxable when a California sublessee returned equipment to the out-of-state prime lessor?
Only if taxable sublease rent applied and the sublessee was required to buy return shipping; an optional shipping service was not taxable.
Was Sundance Natural Juice Sparkler exempt when it was carbonated and contained 70% fruit juice?
No. California corrected an earlier exemption and treated the 70%-juice carbonated sparkler as taxable, prospectively for the addressed retailer from January 1, 1990.
How did California treat film-to-tape, editing, duplication, equipment-with-operator, equipment-only rentals, tape stock, resale certificates, and subcontracted postproduction?
Qualified postproduction and subcontracted services were nontaxable; broadcast duplicates and tape sales were taxable, while equipment-only rental treatment depended on acquisition tax.
Could flights for an aircraft owner's medical corporation count as common carriage when the owner also piloted them as the charter company's employee?
Sometimes. Owner-only flights did not qualify, but multi-passenger flights could if the owner was a genuine carrier employee available for other flights and all terms matched ordinary charters.
Was assembling customer-furnished pages, folders, binders, and kit materials taxable before mailing?
Yes when assembly created a distinct end product, such as a loan folder or binder. Mere preparation of unrelated printed matter for mailing could remain nontaxable.
Which university law-library document-delivery charges were taxable for photocopies, fax-only delivery, rush service, and postage?
Photocopy, standard, and rush charges were taxable; fax-only transmission was not. Actual qualifying postage could be excluded if clearly stated.
Which parts of blood-collection kits qualified as nonreturnable containers when plasmapheresis centers discarded most components and returned plasma?
Only the pooling bag returned with the plasma was exempt on the 1989 facts. Discarded collection components were taxable; cartons needed reuse facts.
How did California's corrected annotation treat an out-of-state aircraft brought into California before or after the historical 90-day period?
Entry within 90 days created a California-use presumption, with fair-rental-value reporting available for lease-only use after a timely election; later entry generally avoided use tax and leasing…
Why was Wonder Bee Royal Jelly exempt while Kiku Royal Jelly was taxable when both were sold in capsules?
Wonder Bee was exempt because its label did not call it a supplement; Kiku was taxable because its label expressly called it a nutritional dietary food supplement.
Was tinting a newly purchased vehicle taxable, and was retinting a used vehicle treated the same way?
Tinting a new vehicle was taxable fabrication. Retinting used windows to their former condition was repair, so labor was nontaxable while materials followed the repair rule.
Was tinting a new vehicle and retinting a used vehicle treated the same for California sales tax?
No. Tinting a new vehicle was taxable fabrication; retinting a used vehicle was repair, with material tax treatment determined by separate charges and the ten-percent test.
Was artwork for a product package exempt because it was used to make an otherwise exempt container?
No. The designer's transferred artwork was taxable finished art; it was used to fabricate the package but was neither the container nor a component incorporated into it, so the container exemption…
Did Amplify D qualify for California's fertilizer exemption when applied to soil or seed to improve germination and seedling vigor?
No. California classified the adenosine-monophosphate product as an auxiliary plant substance specifically excluded from the fertilizer exemption.
Was a quarry owner still the consuming prime contractor when it supplied materials and subcontracted their installation?
Yes, because it had full furnish-and-install responsibility to the land developer. Purchased materials were taxed, but self-quarried rock and aggregate involved no taxable sale to itself.
When were changes to steel dies taxable alterations rather than repairs, and could mixed alteration and repair labor be allocated?
A change producing different boxes was taxable alteration; work improving the die while preserving identical output was repair. Mixed jobs could be allocated with adequate documentation.
How did California tax master recordings made for radio advertising and qualified film or television commercial production?
Radio and other advertising master sales were taxed only on blank recording media. Qualified film or video production services were not taxed as sales; the producer instead consumed the transferred tape.
How did California tax a single-film special-effects corporation's production charges, later stock sale, and liquidation into the studio?
The October 6 opinion treated MSE's special-effects charges as nontaxable qualified production services but made MSE the consumer of incorporated materials. The shareholder's later stock sale to the…
Could a predecessor-creditor petition for redetermination of a buyer's tax liability when the assessment reduced proceeds available through a court-appointed receiver?
Yes. The creditor was directly interested because the remaining liquor-license proceeds could satisfy its related business claim after the tax determination.
If a creditor qualified as a directly interested party and successfully challenged another person's tax determination, did the creditor automatically receive the overpayment?
No. Permission to petition established a direct interest, not ownership of any refund; payment to the receiver would require an appropriate court order.
Did a hand-held Yankauer oral suction tube qualify as exempt medicine?
No. California treated the tube as taxable because it was hand-held for oral suctioning rather than fully worn by the patient.
When did California treat traction materials as exempt body-worn medical products?
Only when fully worn by the patient. An arm sling around the neck or shoulder could qualify, while mere body contact was insufficient.
When did tubular or bias stockinettes qualify as exempt medical products?
Only when worn as an orthotic brace, support, or body-structure correction; operating-room drape or headdress uses were taxable.
Did porcine skin grafts used on burn patients qualify as exempt prosthetic devices?
No. California treated them as taxable temporary biological dressings even though they could facilitate some skin growth.
Were goat, sheep, and bovine sera used as laboratory test media exempt as products of food animals?
No. California treated the sera as taxable because the cited exemption covered live animals, not otherwise-taxable animal-derived products.
When were fecal, leg, biliary, and urinary drainage bags exempt in California?
They were exempt when fully worn by the patient, including a taped-on bag; a bag not worn was taxable unless the ostomy-supply rule applied.
Did an Ewald tube used primarily for diagnostic purposes qualify as exempt medicine?
No. California treated the described Ewald tube as taxable because its primary function was diagnostic rather than qualifying drainage.
Were Entriflex, Keofeed, and enteral feeding tubes exempt medical products?
No. California treated the tubes as taxable because they were feeding devices and were rarely used for another purpose.
Did California exempt colostomy and tracheostomy care kits used for patient self-care?
Yes. The historical opinion treated the self-care kits as necessary related supplies resulting from the qualifying surgical opening.
Were externally connected artificial-heart systems used while awaiting a transplant exempt prosthetic devices?
No. California treated the external blood tubing, mobile pump, and related mechanical equipment as taxable.
How should an auto-parts seller handle sales-tax reimbursement on a refundable core deposit?
Charge tax reimbursement on the exchange price plus the core deposit; if the core is returned, refund both the deposit and its tax reimbursement.
Were cash meals sold to university students by a for-profit independent food-service contractor exempt as school meal sales?
No. The contractor—not the university—made the cash sales and fell outside section 6363's listed school-related sellers, so its student meal receipts were taxable.
How should a $100,000 first-invoice financing incentive be allocated between a mainframe's taxable price and nontaxable interest?
The parties had to allocate it so the taxable-price reduction plus the related 10.52% interest reduction totaled $100,000.
How should a $100,000 financing incentive on a California computer purchase be split between the taxable sales price and nontaxable interest?
The $100,000 first-payment credit was not extra taxable consideration, but it also was not entirely a cash discount against the computer's price. The parties had to allocate it between a reduction…
Could an out-of-state aircraft-parts seller rely on a foreign-air-carrier sales-tax certificate for parts delivered into California?
No. The sales occurred outside California, so the sales-tax certificate did not establish a use-tax exemption. Without a timely valid certificate, the seller had to prove qualifying sole use outside…
Were baseball-card waxpacks taxable when each combination package generally included a stick of gum?
Yes. The Board stated that waxpacks containing a stick of gum and varying quantities of baseball cards were taxable.
Which listed Kodak photographic chemicals were manufacturing aids, and which were treated as incorporated into the finished product?
The memo relayed Kodak's classification of five catalog products as manufacturing aids and six as incorporated into the final product. The live annotation translates those groups into no-resale and…
Could operating-system software or reusable modules qualify within the custom-program exclusion?
Basic operational programs remained taxable when transferred on media, but incomplete reusable modules did not prevent a special-order application program from being custom.
Was an asparagus-sizing machine exempt when its seller delivered it to the buyer's second California manufacturer for precise matching before Washington shipment?
No. The order required California delivery to the buyer's representative, and Washington use tax reportedly paid by the buyer did not offset the seller's sales tax.
Did money returned to a buyer under a court-ordered defective-merchandise settlement reduce the original taxable sales price?
No. The settlement payment was treated as damages rather than a post-sale price adjustment, so the defective-merchandise deduction did not apply.
Were Medifast and Pro-Call 100 exempt as prescription medicines or as food products?
They were exempt as food products, not as prescription medicines. A seller offering only those exempt products did not need a seller's permit.
Were charges for encoding a hidden identifier into television commercials and monitoring broadcasts taxable when results came by printout or electronic data transmission?
No. Encoding was a qualified production service and monitoring was the true object; incidental printouts and electronic reports were nontaxable, but disks or tapes would be taxable.
Was whole, bulk lecithin exempt when its label did not present it as a dietary supplement or adjunct?
Yes. Whole, bulk lecithin was exempt when the label or package did not indicate it was sold as a dietary supplement or adjunct.
Were powdered dried seaweed, algae, and wheatgrass exempt when their labels did not present them as dietary supplements or claim dietary benefits?
Yes. The 1989 opinion treated them as exempt unusual or health foods if their packaging made no dietary-benefit claim; a later note abandons medicinal claims as the medicine test.
Were herbal extracts exempt when they were sold in dropper bottles labeled for use as a beverage?
Yes, if sold as a beverage and not presented as providing dietary benefits. The later annotation removed medicinal claims from the test.
Were one-ounce essential-oil bottles taxable when the labels gave no use and the oils were understood to be scents, not ingested?
Yes, on that assumption. Oils used as scents and not meant to be ingested were not food products, but counsel invited contrary use and carrier-oil facts.
Was aloe vera gel exempt when it was consumed as a beverage and not labeled as a dietary supplement?
Yes. The described aloe vera gel was exempt because it was used as a beverage and was not labeled as a dietary supplement.
Were syndicated automotive market-research reports taxable products when buyers also received presentations, consultation, and newsletters?
Yes. California found that buyers sought the completed reports and that presentations and consultation were incidental; truly commissioned research remained a service.
Does California sales tax apply when a seller routes equipment through its California warehouse for assembly or consolidation before customer delivery?
Yes. When the California warehouse assembles or consolidates the equipment and ships it to the customer, the sale is completed in California and sales tax applies. A direct f.o.b.-shipping-point…
Did a mandatory $1-per-unit end-of-term purchase make a 500-chassis agreement a sale at inception despite a genuine early-termination right?
No. A genuine all-equipment return right made the term nonfixed despite the mandatory $1 end buyout, so the contract was a true lease.
