Were separate charges taxable for recovering platinum and rhodium from exhausted gauze when the customer received a metal-value credit?
Yes. Recovery and refining charges entered the taxable measure; the customer credit excluded only the approximate value of the exhausted metal returned.
Which chemicals used in paper and pulp manufacturing were taxable aids, and which qualified as incorporated components?
Most listed cleaners, bleaches, stabilizers, defoamers, and pitch dispersants were taxable; specified talc, coating, and retained bleaching inputs qualified for resale.
Did a removable and replaceable diving board remain a fixture?
Yes. Its expected replacement when broken, worn, or unsuitable showed that it retained identity as an accessory rather than becoming an inseparable part of the diving-board stand.
Were charges taxable for producing a perfectly typed copy that the customer would photograph and incorporate into a book or pamphlet?
No. California treated the typed copy as a reproduction proof under Business Taxes General Bulletin 62-3, so the typing charges were not taxable.
Could a carrier retain the section 6385 exemption after using the purchased property to haul a payload on its first out-of-state trip?
Possibly. Staff said hauling payload on the first outbound trip could cause the purchaser to lose the exemption, assuming it otherwise applied. The letter reached no final exemption decision.
Did a California laser manufacturer make taxable use of resale inventory by loaning units to out-of-state customers awaiting ordered models?
No. Delivery by common carrier to an out-of-state customer for use there was treated like an out-of-state lease or bailment, not California use.
Did a California laser manufacturer owe use tax when it delivered inventory loaners to out-of-state customers awaiting ordered equipment?
No. The loaners were delivered by common carrier to bailees outside California for use there, then returned to California, checked, calibrated, and placed back in resale stock. The Board analogized…
Was a separately stated admission charge taxable when a theatre restaurant also required patrons to buy a minimum number of drinks or a dinner?
No. Because the admission charge paid for entry to entertainment and the required food or drinks were billed separately, tax counsel excluded the admission from taxable gross receipts.
When was an in-place water-meter sale treated as taxable personal property rather than a nontaxable real-property transfer?
Generally it was real property. It became personal property when a lessee with removal rights sold to a non-landowner buyer who also could remove the meters.
What sales-tax duties applied when an auctioneer sold furnished houses for one lump-sum price?
The auctioneer needed a seller's permit and owed sales tax on the fair retail value of furnishings and other tangible personal property included with the real estate.
How did California tax a subcontract that separately priced design and fabrication of a pump model and professional laboratory testing and reports?
The model's design-and-fabrication charge was taxable, while the separately stated laboratory testing and report charge was a nontaxable professional engineering service.
Was supplying an operated road-base mixing machine a rental or taxable processing, and why were the protested receipts removed here?
The receipts were removed because the lessees had exclusive control. If the owner retained control over the work or operator, the same machine service would be taxable processing.
Did nonprofit educational status exempt film and tape shipped to California television stations from use tax?
No. California treated the use tax as distinct from property tax, so constitutional property-tax protections for nonprofit educational organizations did not create a use-tax exemption.
Was an individual's one-time sale of personally owned equipment used by his corporation occasional despite his separate retail business?
Yes on the hypothetical facts, but only if his other individual-capacity sales during the prior twelve months were normal stock-in-trade sales in the separate business. The Board had not reviewed…
How did California tax separate library-cataloging services, master printed catalogs, and monthly or bimonthly catalog supplements?
Separate cataloging services were not taxable. Six-month or annual master catalogs were taxable, while monthly or bimonthly supplements qualified for the periodical exemption.
Were sales of wrapped food and drinks from open-air carts at a plant taxable when buyers had to take everything to their desks or workbenches?
No, under the 1965 facts. With no counters, tables, seating, building, or parking area for consumption, tax counsel concluded that the operator was not serving meals.
When did a dentist's in-office laboratory consume dental materials, and when did it make taxable sales to other dentists?
The dentist consumed appliances made for the dentist's own patients, but made taxable sales when the lab produced appliances for other dentists, even at cost.
Was a pharmacist's fixed annual family fee taxable when it covered on-call service, prescription records, and cost-plus pricing?
No under the 1965 facts. The fee stayed the same regardless of whether the family bought anything, so it was not included in sales receipts.
Were installed ornamental trees fixtures while installed lawns were materials?
Yes. A nursery furnishing delivered-and-installed purchased trees was a contractor-retailer of tree fixtures, while a nursery installing a lawn consumed the materials used.
Were sales of fire apparatus exempt when made to government agencies, incorporated municipalities, or volunteer firefighters' organizations?
No general exemption applied. California said those fire-apparatus sales were taxable unless another rule made tax inapplicable, such as a qualifying purchase for resale.
Could a retailer claim a sales-tax bad-debt credit when it sold receivables without recourse and the buyer bore the uncollectible loss?
No. The receivables buyer, not the retailer, suffered the loss after the reserve was exhausted, and the memorandum found no authority for crediting one taxpayer for another party's loss.
How did California treat an artist's fee for exclusive architectural renderings and the firm's own use of some drawings?
The entire artist fee entered the sales price of the unique renderings. Drawings the firm consumed in its architectural services would ordinarily be retail sales taxable to the artist, who was…
Did a shoemaker make a taxable sale by trading inventory shoes for $100 of merchandise for personal use?
Yes. Barter was a sale, and the $100 value of the merchandise received was included in the shoemaker's taxable gross receipts.
Did Cinema and Studio qualify as an exempt newspaper or periodical when its content and effect exclusively advertised and promoted two theaters?
No. California found the submitted publication exclusively devoted in content and effect to advertising and promoting the two theaters.
Could a removable diesel generator supplying only a missile-tracking computer qualify as machinery and equipment on a Navy project?
Yes, on the stated facts. It was removable, served the tracking computer rather than building lighting, and federal title passed before contractor use.
When could a drilling-bit retailer deduct the original sale after supplying a replacement bit?
Only when the first bit was defective on initial use and the retailer refunded its entire price plus tax reimbursement. Use-damaged bits and replacements were both taxable.
How did California tax coin investments involving personal investors, out-of-state dealers, brokers holding coins, unexercised options, and private-party sales?
Personal coin investments were taxable retail use, while resale-business inventory was not. Tax also depended on interstate delivery, when title passed, and whether a broker transferred title.
Could a farm labor center be a California sales-tax retailer of meals even though it did not qualify as a retail establishment under the federal Fair Labor Standards Act?
Yes. Tax counsel said the federal term 'retail establishment' was not synonymous with California's statutory term 'retailer,' so the center was a retailer of its meal sales under section 6015.
Could a business buy ammonia for resale when the chemical became incorporated into diazotype prints that it sold?
Yes under staff's stated understanding. Aqua-ammonia vapor combined with the paper's acidic stabilizer, enabled the remaining diazonium salt and coupler to form a dye image, and was treated as…
Did a mixed-use aircraft qualify for California's carrier exemption or avoid tax under the principal-use test?
No. The operator was not a qualifying certificated carrier, the aircraft had intrastate use, and California storage alone exceeded half the first six months.
Were separately stated United Parcel charges excluded when a retailer shipped orders from its business directly to customers?
Yes, if the property was not sold for a delivered price. United Parcel was transportation by facilities other than the retailer's.
Which book-processing activities were nontaxable professional library services, and which were taxable mechanical processing?
Bibliographic description, classification, and card verification were services; applying labels, card pockets, and the college name was taxable mechanical processing.
Which library-preparation services were nontaxable professional work and which were taxable mechanical processing?
Bibliographic description, classification-number work, and card verification were nontaxable professional services. Applying labels, pockets, and a college stamp was taxable mechanical processing.
Were truckers on a retailer's payroll independent carriers when they received employee benefits and were treated as employees for deductions and taxes?
No. Their hauling was transportation by the retailer's facilities, so the related charges were taxable under the periods and documents addressed in the reaudit.
Did a lumber retailer have to refund transportation charges to satisfy the full-price requirement for returned merchandise?
Not for separately stated common-carrier delivery excluded from tax. Taxable delivery by the retailer's own vehicle remained part of the full price and required allocation and refund.
Did calling California franchise dealers 'independent contractors' prevent them from creating collection duties for an out-of-state encyclopedia seller?
No. The dealers solicited orders in assigned territories and collected installments under the seller's authority, so their local sales function made the seller engaged in business.
How did California tax beneficial insects sold or used in agricultural pest-control services?
Direct insect sales were taxable. A pest-control firm was the retailer if it separately charged for insects, but the consumer when they were bundled into its service.
Did an employee owe use tax when a company used its fleet discount as the employee's agent and registration later moved from company to employee?
No if the dealer had already collected sales tax and the employee proved payment. Without proof of tax on the fleet purchase, no clearance should issue.
Were medicines exempt when an employer bought them for its employed physician to treat employees?
Yes. California treated the purchase as made on the physician's behalf when every medicine would be administered by the doctor or under the doctor's direction.
Did a watch service center self-consume replacement parts furnished under a warranty included in the original watch sale?
No. The memorandum treated the warranted parts as sold with the watch at the original retail sale, so furnishing them during warranty repairs created no separate use-tax liability.
Could a retailer reduce taxable receipts by paying nonprofit groups a percentage of purchases made by their members?
No. The group payment was a retailer business expense, not a discount to the actual purchaser, so tax remained based on the full customer charge.
Did separate purchase orders for girders and erection create two tax transactions?
No. Because both documents had the same date, covered the same 64 girders, and were split only to correct a bidding omission, California treated them as one construction contract.
How did California tax hand typing, mimeograph work, and a typing business's proposed sale of a used electric typewriter?
Hand typing was a nontaxable service and the typist consumed the materials. Mimeograph work was taxable, as was a retail typewriter sale unless made for resale.
Could dredging equipment qualify as a foreign-commerce sale when it was delivered to a purchaser-furnished barge and carried to the purchaser's foreign job site?
Yes, in tax counsel's opinion. The transaction fit the cited foreign-commerce rule because the purchaser furnished the barge, the equipment was carried abroad, and the rule's delivery conditions were met.
How did California tax engineering drawings, installation labor, on-site fabrication, and separately billed trucking for a custom-built pipe organ?
The required drawings were part of the taxable organ sale. Installation labor and qualifying separately billed delivery were excluded, but on-site fabrication had to be distinguished.
Did temporary California custody for a buyer's visual inspection or operational testing defeat exemption when the seller still had to ship outside the state?
No. Exemption remained if custody was temporary, the contract still required seller shipment outside California and the seller actually made that shipment.
Were engineering drawings, installation labor, on-site fabrication, and separately billed trucking taxable for a custom pipe organ?
Drawings and fabrication were taxable parts of the organ sale; installation was excluded, as was separately billed nonretailer trucking under the described terms.
How should a replacement-engine seller treat a customer allowance that included both defect compensation and trade-in value?
The seller had to separate the amounts. A genuine defect allowance reduced tax, but the defective property's trade-in value remained taxable consideration.
Could incorporators avoid personal tax liability by asserting corporate status after applying for a seller's permit as a partnership?
No, according to counsel. The incorporators later certified that they operated as a partnership, and the Board relied on that representation by requiring $1,200 rather than the discussed $3,500…
Were charges for creating an original musical arrangement taxable, and did the result change for multiple copies or printed sheet music?
The arranger's original manuscript was a nontaxable creative-service work product, but making multiple copies was taxable fabrication, as was selling printed sheet music.
Was a musical arranger's original manuscript taxable, and what changed when the arranger supplied multiple copies?
The original manuscript embodied a nontaxable arranging service. Preparing multiple copies was fabrication of tangible personal property, so the copies were taxable.
Did a shopping-center doughnut shop owe tax on bulk doughnuts sold for off-premises consumption because the center provided a general parking lot?
No, on the submitted layout. The common parking area did not make the shop a drive-in, so bulk takeout doughnuts remained exempt while doughnuts eaten on the premises or patio were taxed.
Was labor taxable for restoring used pipe, and what changed when old lengths were welded into longer pipe?
Restoring used pipe to its former condition was nontaxable repair labor, though materials remained taxable. Welding old lengths into longer pipe was taxable fabrication.
Were charges for designing and improving an automatic-packaging invention taxable when the contract required no tangible end product?
No. The charges were for design and engineering services, but the provider consumed taxable materials bought for the work; a required end product would change the result.
What installation duties did California tax counsel say a window supplier ordinarily needed to be treated as a contractor-consumer?
Counsel said the supplier had to be contractually responsible for installation and ordinarily install itself or hire someone other than its prime builder-customer. Counsel requested more facts…
When were school meals furnished to employees other than students or teachers taxable after the 1963 amendment to section 6363?
They were taxable only when the employee paid a specific charge, including by payroll deduction. A bookkeeping value assigned to meals furnished as compensation was not itself a specific charge.
Was a gallery the retailer when an owner left a painting there for sale?
Only if the gallery had beneficial use or could transfer title by its own act. If it merely held the painting and brought buyer and owner together, tax instead depended on whether the owner was in…
Did printer delivery to a mailing agency exempt advertising materials when the buyer decided later which copies the agency would mail out of state?
Buyer-only instructions after delivery to the agency were insufficient. The seller had to act under a contract or supplement requiring out-of-state shipment, with actual mailing and destination records.
Was a hotel supply company's 5% procurement fee taxable when it sometimes acted as purchasing agent and sometimes sold as a franchised dealer?
Not when it acted as disclosed agent and vendors invoiced the hotel; taxable when it bought as principal and resold the property.
Could undated and unnumbered travel brochures qualify as periodicals when Union Oil issued a different weekend-drive brochure to customers each week?
Yes. Their general-interest content, weekly series, advance notice of the next subject, and nominal advertising made them periodicals despite lacking dates or numbers.
