Were a vendor's sales of negatives and plates to printers retail sales or sales for resale?
They were taxable retail sales if the printer used them before transferring title to the customer, but sales for resale if title passed before the printer's use.
Were store sales exempt exports when Mexican purchasers received the goods in California and then transported them to Mexico?
No. Delivery to the buyers at the California store came before export; the cited rule required seller delivery to the purchaser-furnished conveyance that would carry the goods abroad.
Was federal excise tax on photographic apparatus included in California gross receipts and sales price?
Yes. California classified it as a manufacturer's excise tax and included the federal charge in the sales- or use-tax measure.
Did a venetian-blind contractor need a seller's permit and returns when buying installed fixtures tax-paid?
Yes under the historical rule. The Board said a venetian-blind contractor remained the retailer of installed fixtures, had to retain its permit, and had to file periodic returns even when it bought…
Which work on customer stones was taxable fabrication and which was nontaxable inspection, minor modification, or used-ring work?
Drilling, finishing rough stones, and first-time ring mounting were taxable. Inspection cuts, minor redrilling, and mounting in previously used stone rings were not.
Did a retail fish market need a seller's permit when it sold only fish and other food for human consumption?
No, if the market sold only fish or other food products for human consumption. Selling any other item required a permit, and tax applied to nonfood retail sales unless another exemption covered them.
Were rabbits sold to doctors and laboratories exempt despite their laboratory use?
Yes. California treated rabbits as food animals regardless of laboratory use, while mice and guinea pigs did not qualify for that exemption.
Was a steamship company's operation of a hotel part of its common-carrier business for section 6385?
No. Property bought for hotel operations was not used in the steamship company's common-carrier business and was not exempt on that basis.
Were beer-can openers furnished by a brewery to beer retailers self-consumed or resold?
They were treated as resold, not self-consumed. Sales to on-sale dealers that used the openers were taxable, while off-sale dealers were presumed to pass them to beer buyers; the source recommended…
Who received a retailer's California tax-security deposit at closeout when a third party originally supplied the money?
The permittee received it. Staff said the deposit had to be returned to the retailer unless the retailer assigned the deposit to the third party.
Did California tax chrome plating used machinery rolls differently from plating new rolls?
Yes. Plating used rolls was repair and the plater consumed unitemized materials; plating new rolls was taxable production or fabrication.
Were separately stated charges to tune, test, and adjust a completed organ during installation taxable?
No. Work adapting a completed organ to a building's acoustics was installation labor when segregated from the organ's sales price.
Were sales of postage stamps by a private philatelist taxable when buyers acquired them as collectibles rather than for postage or resale?
Yes. Private sales of stamps to collectors for purposes other than postage or resale were taxable, subject to the stated interstate-commerce and resale exceptions.
How did California apply sales and use tax to racehorse sales, purse-race entries, and claiming races?
Racehorses were generally taxed like other nonexempt property. Entering a horse in a purse race could be taxable use, and claiming-race seller rules changed in 1943.
Was a truck sale exempt when the seller's employee drove it from California to the Oregon buyer while hauling the buyer's freight?
No. Hauling freight placed the truck into service in California; whether the driver acted for the seller or the buyer changed the tax measure, but not the conclusion that tax was due.
Did a dealer's 500-mile break-in of English-built cars create taxable use before resale?
No, if the driving served only to prepare the cars for customer delivery. Other use beyond break-in, demonstration, or display could make the dealer taxable.
Were repair parts and operating items for kelp-harvesting watercraft exempt under California's watercraft exemption?
No. The operator's kelp-harvesting vessels were not used for interstate or foreign transportation for hire or for commercial deep-sea fishing. California therefore taxed repair parts and other…
How was tax split when a farmer and the United States were separately obligated to pay portions of conservation-material purchases?
The federal government's separately obligated share was an exempt United States purchase, while the farmer's separately obligated share remained taxable.
Could printers hold completed large orders for later shipping instructions, report tax when shipment occurred and exempt goods sent outside California?
Yes, if the order required shipment under later instructions and shipment occurred accordingly; tax applied only to goods sent to California points.
When was kelp exempt when sold as a poultry or animal food supplement?
Kelp was exempt when sold as feed for qualifying food animals or animals held for regular-course sale; qualifying interstate sales were also outside the tax.
Was a research contract taxable when it required development and assignment of engineering data but no manufacture or delivery of a machine?
No. The contractor sold R&D services and consumed the materials because the contract required information, not a delivered machine; a research machine remained with the contractor.
Were weatherstripping and insulation contractors consumers of the materials used in their construction contracts?
Yes. Weatherstripping and insulation were materials, so tax applied to their sale to the contractor-consumer rather than to the construction contract charge.
Did the Oakland Public Schools bulletin remain regularly issued when it ran weekly for 35 weeks and paused during summer vacation?
Yes. California found that the weekly school-year schedule with a summer hiatus still met the average-interval requirement.
Why did a 1950 California letter recommend no adjustment for x-ray and gamma-ray pictures furnished to shipyards?
Agency contract and voucher records showed x-ray pictures sold at stipulated prices, and the letter treated gamma-ray pictures the same way. It found inadequate evidence for visual-inspection relief…
Was a charge for engraving new merchandise taxable when the university customer supplied the items?
Yes. The opinion treated engraving new customer-furnished merchandise as taxable fabrication or processing; it reserved the treatment of used articles for additional facts.
How did staff measure tax when a company sold property to operators who became co-owners while the company might retain an interest?
Staff measured tax by the consideration for the interest actually transferred. A complete transfer used 100% of the consideration; if the company remained an operator and co-owner, its retained…
Was a 10-percent negligence penalty proper when aircraft-radio sales were omitted under a bona fide export-tax dispute?
No. Counsel recommended removing the penalty because the taxpayer's export position presented a genuine unresolved legal dispute rather than negligent reporting.
Were charges taxable for firing ceramics furnished by students or other consumers?
Yes. Firing was a step in producing or creating the finished ceramic article and was taxable processing of consumer-furnished property.
Was a weekly pension-advocacy newsletter an exempt periodical, and did the printer make a retail sale?
It qualified under Ruling 50, and the printer apparently sold it for resale because the corporation charged subscriptions.
Were charges for assembling steel lockers and shelving taxable, and could separate installation of completed shelving be exempt?
Assembly was taxable fabrication because the parts were not yet lockers or shelving. Separately stated labor installing the completed property could be exempt.
Did a donor owe California use tax on advertising gifts deposited in the mail outside California for in-state recipients?
No under the stated rule. Deposit in the mail constituted delivery and passed title at the out-of-state mailing point, so the donor did not make the taxable use in California.
Was a printer's separate engraving charge part of gross receipts from labels or posters when the customer never received the engraving?
Yes when the finished goods sale was taxable. The engraving remained the printer's property, and its billed cost was a production expense included in receipts.
Did the historical ice exemption cover ice preserving fishermen's catch from grounds outside California territorial waters to in-state docks?
Yes, conditionally. Assuming the catch was for human consumption, Associate Tax Counsel said ice sales would appear exempt under Ruling 60 if the ice preserved fish while moving from fishing grounds…
Did California treat Wake Island and Canal Zone shipments as exports, and did that alone exempt a sale?
The annotation says yes to export status, but a sale was exempt only if regulation requirements were met. The PDF names neither places nor authorities.
Were petrolatum and mineral oil exempt when bakeries used them to lubricate equipment and some entered the dough?
No. The bakeries bought the products to lubricate production equipment, so the sales were taxable even though some lubricant entered the finished bakery goods.
Did a caravan permit exempt a truck or trailer sold and delivered in California for out-of-state removal?
No. A purchaser's permit and actual removal did not turn a California sale and delivery into exempt interstate commerce.
What happened when a contractor bought fixtures tax-paid at 2½ percent but installed and sold them after the rate rose to 3 percent?
The contractor owed the half-point difference. The earlier tax-paid purchase was only a prepayment against tax due when the later sale occurred.
Which inputs used to grow nursery stock for resale were exempt from California sales and use tax?
Seeds, annual plants, qualifying fertilizer, resale nonannual plants, and nonreturnable containers sold with the stock were exempt; other production inputs were taxable.
Did a pet store owe sales tax on the full selling price of consigned pets, or only on its commission after deducting animal-care expenses?
Tax applied to the full gross receipts. The store was the retailer of consigned pets and could not deduct commissions, keeping costs, labor, losses, or other expenses.
Was a truck purchased for California use when it first served a Kansas business and came here only after the owner failed to sell it there?
No. The Kansas business use and attempted Kansas sale showed that California-use intent arose only later.
Was aviation gasoline exempt when delivered to the purchaser in California but partly consumed outside the state?
Generally no. California delivery made the sale taxable despite planned and actual out-of-state use unless the transaction independently satisfied one of the cited interstate or foreign-commerce…
Was a separately stated charge for limited or unlimited reproduction rights part of the taxable price of a sold photograph?
Yes. The letter treated bare title without the intended reproduction use as incomplete, so every amount required to buy the physical photograph for reproduction entered taxable gross receipts.…
Which vessel lights qualified as component parts: bulbs, installed lights, or portable lamps?
Installed lights and lanterns qualified when substantially affixed or attached during use. Light globes did not. Flashlights, battle lanterns, oil lamps, extension-cord lights, and other movable…
How was California tax measured when a California dealer delivered a car in Michigan and the buyer later brought and used it here?
Sales tax did not apply to the Michigan delivery, but use tax did on California use; with no transport charge, the actual vehicle price was the measure.
Were tariffs and corrective tariff supplements exempt periodicals when both were published at irregular intervals?
No. California recommended taxing their retail sales because the publications were irregular and the supplements might not be periodicals at all.
Did a metal polisher need a seller's permit when working only on articles customers would resell?
No, if the business worked exclusively on metal articles for customers who resold them; it could seek cancellation of its existing permit. Processing or electro-polishing articles furnished by…
Could company house organs qualify as exempt periodicals when issued regularly at stated intervals of three months or less?
Yes, if issued regularly and consecutively and containing general-interest material rather than advertising exclusively.
How were undercoating charges treated for new cars sold by dealers versus used cars already owned by customers?
New-car undercoating entered the vehicle's taxable price; a person undercoating a customer-owned used car was treated as consumer of the materials.
Could a photographer buy color film for resale when the photographer would actually resell that film as the finished picture or part of it?
Yes. The letter treated color film actually resold as the finished picture or part of it like photographic paper bought for resale, so its sale to the photographer was not taxable. The same letter…
Did peat moss qualify as exempt fertilizer under California's historical rule?
No. California relied on the Department of Agriculture's classification of peat moss as a soil amendment, not fertilizer.
Could an employer give a caterer a resale certificate when the caterer furnished meals and the employer charged employees through payroll deduction or another method?
Yes, if the employer bought the meals and resold them to employees under the cited exemption. If the caterer sold directly to employees, the employer was not a resale purchaser and the exemption did…
Must a California finance company hold a seller's permit when it repossesses property and resells it?
Yes, when the finance company makes its own repossessions and resells the repossessed property. The 1987 amendment states that those finance companies must hold California seller's permits.
How did California tax mandatory and optional television parts warranties and a labor-only service warranty?
A mandatory parts warranty joined taxable television receipts and its parts were for resale; an optional parts warranty made the seller the parts consumer.
When was elevator assembly taxable fabrication rather than nontaxable installation?
Separate assembly of an elevator was taxable fabrication, but inseparable onsite assembly and installation was installation of the taxable component parts.
Could schools buy soft drinks for resale as part of exempt student or teacher meals, and how were separate snack-bar or carnival sales treated?
Drinks served with qualifying school meals could be bought for resale with a special certificate notation. Separate snack-bar, school-store, or carnival sales were taxable and required seller-permit…
Could a retailer deduct federal tire excise tax or a trade-in allowance from California gross receipts?
No. The tire charge was a manufacturer's excise tax, and the agreed trade-in allowance also remained part of the full taxable selling price.
Were manufacturer-installed metal windows and doors materials, and what tax measure applied?
They were millwork materials, so the manufacturer-contractor consumed them and was taxed on the cost of the raw materials used to fabricate them.
Could a used-car seller exclude an abandonment charge from the sales-tax measure?
Yes, under the historical staff view, if the charge was separately stated and not disproportionate to the car's selling price; any tax reimbursement collected on it still had to be checked.
Did California treat the 13-by-17-inch fiberboard sheets reviewed in Annotation 195.0400 as taxable purchases?
No. The memorandum concluded that the sheets were nonreturnable containers and could be purchased without tax.

It was taxable tangible personal property, not a realty improvement. Only separately stated actual installation was excluded; design and assembly remained taxable.
