Were charges for addressograph plates and preliminary mailing work taxable when the prepared materials went to another mailing house for final mailing?
Plate charges were taxable when title passed to the customer, but folding, collating, and stuffing remained nontaxable mailing services despite transfer to another mailing house.
Did attaching a separately purchased tax-paid motor to a tax-paid boat substantially change the leased property?
It depended on fabrication: simple bolting or clamping did not, while significant alterations such as shafts, wiring, or controls could change form.
Was a tourist-coupon promoter taxed on distributor receipts or on the cost of printing the coupons?
The source treated the promoter as the consumer of the printed coupons, so sales or use tax applied to its coupon cost. No further tax was due on the amounts the promoter received from distributors.
Did a contract label saying a caterer sold employee meals to an employer for resale establish that the transaction qualified as a sale for resale?
No. The Board could examine the contracts and actual performance; if the substance showed the caterer made the retail meal sale, the caterer's gross receipts were taxable despite the resale label.
Were measles vaccine and its single-dose containers exempt in a large community vaccination program?
Yes. California found a doctor-patient relationship for each recipient, exempted the preventive vaccine as medicine, and exempted the containers with it.
Were extra charges taxable for adding heel inserts, changing heels, or stretching men's shoes?
The extra charge was taxable fabrication when performed on new shoes. Replacing worn soles or heels on shoes that were no longer new was classified as repair work.
Did temporary fitting tacks substantially change tax-paid tuxedos before rental?
No. Because the tacks were removed after each rental and did not substantially change the garments, the rental receipts were excluded under the historical rule.
Were a one-time community-antenna installation fee and monthly television-signal service charge taxable when all equipment remained company property?
No. The company consumed the wire, poles, and equipment; subscriber charges were services rather than sales or rentals of property.
Was anchor chain delivered to a Chilean-flag naval vessel in San Francisco an export because the ship constituted foreign territory?
No. A foreign flag alone did not make shipboard receipt a foreign-country delivery or export, so counsel treated the California retail sale as taxable.
Which promotional assignments of new vehicles qualified as demonstration or display, and which were taxable transportation or accommodation use?
VIP loans, pace cars, automotive-editor cars, and employee demonstrations qualified. Repair-customer, studio, ski-lodge, and sports-team assignments were taxable.
How were community-antenna television systems and subscriber charges taxed?
The company consumed the wires, poles, and equipment as materials, so tax applied on its purchases. Subscriber installation and monthly signal-service charges were not taxable property sales or rentals.
When were nonmedicine medical supplies furnished by hospitals under Medicare or California medical assistance exempt?
Under the 1966 letter, Medicare supplies were exempt only to the extent the United States contracted with and paid the hospital directly. Patient-paid Medicare supplies remained taxable despite…
Was Vimin No. 64 exempt when sold as a mineral additive for cattle feed?
Yes. California treated the dolomite-and-kelp product as exempt animal feed when sold for consumption by range or dairy cattle.
Could a construction contractor obtain a seller's permit only to claim the out-of-state-use exemption?
No. Section 6072 required an active selling business. An unrevoked permit still supported section 6386 while valid, but it could be revoked if the contractor was not actually a seller.
Did leasing a replacement chassis become taxable when the lessee moved an old truck body onto it?
No, on the stated assumptions. The lessor supplied the tax-paid chassis in the same form acquired, and the lessee's body attachment required no significant fabrication.
Were communion wafers exempt because they were religious items or because they were food?
They were exempt as food products for human consumption, not under a general exemption for religious items or Sunday School materials.
When were medical-oxygen sales exempt for individual prescription users and state-aided patients?
California exempted prescribed patient oxygen and Casey Bill sales billed to the state's fiscal agent, but taxed rentals of excluded medical equipment.
Did a monthly California Appaloosa Association catalog of horses available at auction qualify as an exempt periodical?
No. Ruling 50 excluded catalogs, so monthly issuance and member distribution did not exempt the association's catalog sales.
Could a separately stated automobile-insurance charge be excluded from taxable rent?
Yes, if the insurance benefited the lessee and the lessee could buy it from any insurer rather than being required to buy it from the lessor.
Was a demountable jet-aircraft noise-suppressor system designed to move between air bases machinery and equipment?
Yes. Its ready removal as a unit and intended relocation between air bases supported resale treatment as machinery and equipment owned by the United States.
Were fees for selecting, photocopying, and furnishing police and medical records taxable services or sales of property?
They were taxable sales of the finished copies. The source treated the records as the transaction's true object, included selection and doctor fees as production expenses, and required a seller's permit.
Were receipts taxable when a service selected, copied, and delivered existing police reports and hospital or doctor records for customers?
Yes. Customers bought finished copies, while selection work and doctors' access fees were nondeductible expenses of producing the taxable property.
Did pulling progressive and finished proofs or insurance Scotchprints before outside shipment create taxable use of the photoengravings?
No. Pulling the proofs and Scotchprints was not taxable use of the engravings, but a separate charge for those items was taxable.
Did an every-other-week price/order book remain an exempt periodical after California amended Ruling 50 to exclude catalogs?
No. The amended rule excluded catalogs, rescinding the 1952 exemption letter and making user and business-use printing charges taxable.
Did an out-of-state salesperson make a California fire-truck dealer an out-of-state dealer for section 6388?
No. The seller remained a California dealer, although a separate Washington accessories dealer taking orders could qualify if every other condition was met.
Were receipts taxable when an ex-tax aircraft was delivered to a lessee in Mexico for exclusive use there?
No. The opinion found no taxable California rental period because the aircraft would be delivered in Mexico and used exclusively there.
Could flavoring and preservative ingredients be bought tax-free for use in exempt animal feed?
Yes, when they became component parts of exempt feed. The same ingredients were taxable when incorporated into nonexempt feed such as the described pet food.
Were the described local and central-station burglar-alarm contracts equipment leases?
No. Equipment was incidental to an integrated alarm service: the company retained control and access and responded at the premises after each alarm.
Was diesel loaded into Mexican fishing boats export cargo because it was transported and burned outside United States territorial waters?
Counsel recommended no: it fueled fishing, not carriage to a foreign destination. The recommendation expressly awaited California Supreme Court review.
Was equipment used at a customer's premises leased when the service provider retained all possession and control?
No. Contracts provided odds/payoff information while possession, custody and license to use equipment stayed with provider/personnel.
Was a mandatory electrical-appliance service-warranty charge taxable when separately stated on the customer's bill?
Yes. A mandatory warranty charge was part of taxable gross receipts from the appliance sale whether bundled into the price or stated separately.
Could one corporation simultaneously transfer substantially all divisional business assets to several wholly owned subsidiaries and still qualify as an occasional sale?
Yes on the stated assumptions. Audit staff calculated that transferred depreciated book value was well over 80 percent, and counsel required every transfer to the wholly owned subsidiaries to occur…
Did a dealer owe use tax after withdrawing a nondealer trade-in from inventory for personal use?
Yes, unless the use was for demonstration or display. Because the dealer did not register the trade-in, it had to pay the use tax directly to the Board.
Did the Soldiers' and Sailors' Civil Relief Act bar California use tax on service members' vehicle purchases?
No. The memorandum distinguished use tax from the vehicle license fee at issue in Buzard, while recognizing separate statutory rules for some out-of-state purchases.
After August 1, 1965, could a motion-picture lessor elect to treat film rentals as taxable sales?
No for newer films under the historical rule. The lessor consumed motion pictures, while pre-change films could retain a prior rent-tax election.
Were fabricated steel reinforcing bars installed in concrete materials, and what was the manufacturer-installer's tax measure?
They were materials, so the manufacturer-installer's measure was its raw-material cost; separately sold bars instead used their retail selling price.
How were automotive-plant spray booths, ovens, conveyors, cranes, and transfer cars classified?
Booth and oven structures, conveyor frames, rails, and crane supports were materials; moving conveyor and crane parts were retailed components; transfer cars were personal property.
Were subscription graphs showing hospital-industry trends taxable printed property or a nontaxable data-compilation service?
They were taxable printed property. The graphs were prepared for any subscriber rather than one customer's special order and lacked literary content for periodical treatment.
Were exterior fire-alarm systems installed on a federal project telephone or telegraph lines, or taxable real-property improvements?
They were real-property improvements. California rejected telephone-or-telegraph-line treatment and taxed the contractor's purchase of the system components.
Was a periodic fluorescent lamp-and-ballast replacement contract a construction contract?
Yes. California treated the service arrangement as a lump-sum construction contract, deleting the lamp markup already reported at cost and reducing unreported ballasts to contractor cost.
Were timber-tree seeds and seedlings exempt when bought solely to grow trees for harvest and sale?
Yes. Seeds qualified under the plant rule and seedlings as resale inputs, but a specific intervening use such as erosion control, seed production, or recreation made them taxable.
Were ready-mix concrete batching and in-truck mixing taxable processing, and did a construction-subcontract label change that result?
Yes. Weighing and batching the ingredients and mixing them in the truck were taxable processing of wet concrete; the subcontract label did not make the supplier a construction contractor.
Did a one-continuous-trip permit exempt a vehicle delivered to a service member in California?
No. California delivery made the delivering dealer liable for sales tax even when the buyer was in transit and immediately removed the vehicle.
Was shipment under a stocking agreement 'final transportation' when the seller still stored the goods, paid property tax, bore loss risk, and could not yet demand payment?
No. Those continuing seller obligations showed no present sale or delivery, and a bare title-transfer recital did not turn shipment to the stocking location into final transportation.
Which American Research Bureau audience reports qualified as exempt periodicals, and could bundled charges be allocated?
Diary National Reports met the historical content and frequency tests, but five less-frequent report series did not.
Was a retailer's separately stated charge taxable for bolting together factory-shipped steel shelving at the buyer's premises?
Yes. Bolting and assembling the knocked-down shelving were production steps, so the retailer's separately stated labor charge was subject to sales tax.
Was use tax refundable on a vessel received as trade-in consideration and resold three weeks later without any intervening use?
Yes. The vessel was acquired solely for resale and used only for demonstration and display, so there was no taxable storage, use, or consumption before resale.
How did California distinguish true research-and-development contracts from custom manufacturing, especially when a prototype was built, used, and transferred?
R&D primarily buys information; custom manufacturing buys an item. Experimental prototype materials bore use tax, and a later prototype transfer was separately taxable.
Was a purchase of more than 7,000 already-developed scientific drawings and sketches a taxable purchase of tangible personal property or a nontaxable intangible?
It was taxable tangible personal property. California recommended no refund because the buyer purchased existing physical drawings, not research services developing information.
Could a caterer exclude charges for parking, security, and wrap attendants from taxable meal receipts?
Yes, if the caterer identified the specific charges in its records and affirmed that those attendants did not also serve food or drinks; otherwise the audit adjustment was not allowed.
Could a direct-sales retailer deduct merchandise credits earned by hostesses who held parties, invited guests, and delivered orders?
No. The hostess services were bargained-for noncash consideration, so the credit plus any cash balance made up the taxable selling price.
Did Ordram 5 Granular qualify for California's fertilizer exemption when rice farmers used it to control watergrass?
No. The product was a selective herbicide and weed killer, not a plant nutrient, so it did not qualify as exempt fertilizer.
Was a partnership's transfer of substantially all business assets to a new corporation exempt even though outside investors bought stock shortly afterward?
No tax was recommended on the limited-partnership-to-corporation sale. Substantially all business assets moved while ultimate ownership remained substantially the same, and the Corporations…
Could a steel-scaffold manufacturer exclude delivery, assembly and dismantling charges when customers could rent without those services?
Yes, if each service was genuinely optional and separately stated. Rent on the manufacturer-built scaffold itself remained taxable.
Could a California dealer exclude both freight legs when equipment moved from a Midwest factory to the manufacturer's Nevada warehouse and then to the customer?
No. Only separately stated freight from the Nevada shipment point directly to the California customer was final transportation; factory-to-warehouse freight remained taxable.
Did a shopping guide qualify as an exempt periodical when roughly 30 square inches were possible general-interest content and 1,680 were advertising or product publicity?
No. California found that the issue clearly failed the 10 percent nonadvertising test, including when distributed alone as a throwaway.
Could portable hospital machines and doctor call units pass through three contractor tiers as property for resale to the United States?
Yes. Because the items stayed unattached and federal title applied, each contractor tier could buy for resale and the prime contractor's federal sale was exempt.
Did directing part of a painting's required price to charity reduce the California taxable sales price?
No. The buyer had to pay $750 to acquire the painting, so the full amount was taxable even though $250 went to charity.
Were aircraft parts and engines exempt after out-of-state installation when their aircraft later operated in California?
Only if the installed aircraft received substantial actual out-of-state service for six months without California use; standby holding was not enough.
Did withdrawing disposable blood bags from California resale inventory for a company-controlled out-of-state plasma program trigger use tax?
No. Although the bags were not sold, their California withdrawal solely for transport and use outside the state fell within section 6009.1.
