Was a sawmill taxed when it used lumber from its own production for repairs and added construction at its California plant?

Yes. The self-consumed lumber was taxable, measured by the proportional purchase cost of the logs from which it was cut.

1953-01-14

Was a separately stated $40 installation charge for a garbage disposal unit included in the California sales tax measure?

The 1953 memo treated the unit as a taxable fixture but said the separately stated $40 installation charge left the tax measure the same as a sale without installation.

1953-01-12

Was a direct transfer of cash, equipment, and leased vehicles to a newly formed corporation for all its stock taxable?

No under counsel's assumptions. X transferred cash, equipment, and 50 leased Chevrolet vehicles directly to transaction-formed Y, which had no prior assets and issued all authorized stock directly…

1953-01-07

Was a corporation's equipment transfer to a minority shareholder for surrender of $6,000 in stock an exempt occasional sale?

No. Counsel assumed permit-activity use and said both exemption conditions failed: the continuing corporation transferred only part of its property, and ownership shifted to one former nonmajor…

1953-01-07

Was a sale exempt when export goods showed their foreign destination and the seller delivered them to a carrier supplied by the purchaser?

Yes, on the stated facts. Delivery to the purchaser's carrier began the export journey because the marked goods were received for shipment abroad without further packaging or processing.

1953-01-06

Were feed and medicine purchases by a tropical-fish breeder taxable?

Feed was exempt because the fish were sold in business, but medicine was taxable; the letter also taxed breeding fish and tank equipment.

1952-12-22

Were tropical breeding fish exempt when bought by a business that raised and sold their offspring?

No. California taxed the breeding fish because tropical fish were not ordinary food animals and the breeders themselves were not bought for resale.

1952-12-22

Did a California f.o.b. point prevent exemption when a retailer contracted to ship goods to an out-of-state consumer?

No. The f.o.b. point could be inside or outside California if the contract required out-of-state shipment, the goods actually shipped out, and the retailer delivered them to the carrier.

1952-12-18

Was one partner's sale of her ice-cream business share, including fixtures and equipment, an exempt occasional sale?

The source could not decide without identifying the seller. The sale could be exempt if B sold individually and had made no other individual tangible-property sales in twelve months; it was taxable…

1952-12-16

Did bar merchandise lost through breakage, spillage, theft, fire, or unexplained disappearance create tax on self-consumed resale inventory?

No if the loss was bona fide, adequately documented, and occurred without intervening taxable use.

1952-12-15

Should a seller's credit for forms not shipped also refund the related sales-tax charge?

Yes. The short shipment corrected a mistake, so tax applied only to the corrected sale amount and the customer should receive the corresponding tax credit.

1952-12-15

Was an automobile intermediary the taxable retailer when it obtained title, signed bills of sale under power of attorney, or delivered owner-signed bills to buyers?

Yes. Because the company had and exercised power to transfer automobile title, California treated it as the retailer and included the sales in the tax measure.

1952-12-15

Were extensive incinerators built on brick and concrete bases with onsite brickwork materials or fixtures?

They were materials under the historical rule because they were extensive outdoor structures on brick and concrete bases and their brickwork was performed at the site.

1952-12-03

How did installation method affect whether mirrors were personal property, materials, or fixtures?

A wire-hung mirror remained personal property, integral mirrored walls were materials, and framed mirrors securely attached by screws could be fixtures under the historical rule.

1952-11-28

Did later out-of-state use prevent tax when broadcast kinescopes were first used at California stations?

No. California treated first use here as purchase for California use even though the kinescopes were later used elsewhere.

1952-11-10

Were The First Presbyterian and a separate morning-service sheet both exempt church periodicals?

No. Paper and printing for The First Presbyterian were exempt, but the separate hymn-and-sermon sheet was a taxable program lacking substantial news content.

1952-11-06

Could a social club or fraternal organization issue a resale certificate to its caterer when it served meals less than once a week?

No. Under the cited rule, the club was the consumer when meals were served less frequently than weekly. Tax on the caterer's charge then depended on whether it sold meals or only food the club…

1952-11-05

Was a publication company's one-time use of a returned photograph taxable when the photograph could no longer be reused?

Yes, but only if the reproduction process treated the physical photograph so harshly that it was unusable after return. The 1952 letter then treated the one-time transfer as a lease in lieu of sale…

1952-11-05

Could nurseries buy metal cans tax-free when plants grew in the cans before being sold with them?

Yes. Plant growth in the cans did not defeat the nonreturnable-container exemption when the nursery made no other use and sold each can with its plant.

1952-11-05

When did California's historical advice treat a public administrator's estate-property sales as taxable?

The count was estate by estate: one or two sales during a particular administration were untaxed, while three or more substantial sales in twelve months were taxable. Resale sales were excepted, and…

1952-10-24

Were an estate's liquidation sales exempt because the testator had not operated a related business during life?

No under the historical advice. The unidentified sales made and planned were sufficient in number, scope, and character to require a permit, so consumer receipts were taxable. Sales to dealers,…

1952-10-24

Who consumed window materials when the prime contractor supplied them and paid a subcontractor only for installation work?

The prime contractor was the consumer because it did not sell the sash to the subcontractor, supplied the materials, and remained responsible to the customer for the full installation.

1952-10-24

Did separately purchased helicopter airframes, blades, engines, instruments, and radios qualify as aircraft under section 6366?

The source did not finally decide. It said a complete helicopter was aircraft and parts generally were not, but left open whether the principal airframe-and-blades purchase itself counted.

1952-10-24

Could a dealer furnishing factory-warranty parts for a car sold by another dealer treat the replacement as a resale transaction?

Yes. The servicing dealer could act as the selling dealer's agent, allowing the part transfer to be treated as for resale if records showed that agency transaction.

1952-10-22

Could a horse seller treat one California sale as occasional by ignoring numerous horse sales made outside California?

No. Staff counted sales wherever made when determining retailer status; the California sale could qualify only if total retail sales everywhere were two or fewer in the relevant 12 months.

1952-10-21

Were fire-protection items ordered and paid for by a county treated as sales to the federal Forest Service because delivery went to its garage?

No. Staff treated the county as the buyer because it issued the purchase orders and warrants, and viewed the county-Forest Service arrangement as cooperative rather than a resale; refund denial was…

1952-10-02

Did California treat a tipster as selling printed tip sheets or consuming the cards while performing a service?

California treated the tipster as consuming cards in a service, not selling tangible property; counsel admitted doubt, while the live annotation adds the printer-tax result.

1952-09-30

Could fruit packing houses buy soda ash and borax for resale because some chemical might remain on the produce?

No. Soda ash cleaned impurities, while borax primarily destroyed existing spores and mostly left in the bath; any residual protection did not control.

1952-09-26

Could bulbs qualify as exempt annual plants when destroyed after one growing season?

Yes, if the bulbs were actually plowed under or otherwise destroyed after one season and their products were sold in the regular course of business.

1952-09-19

Did fishing-vessel owners resell beer, wine, and other nonfood supplies when all crew members repaid equal shares of the voyage's grocery cost?

No. The owners bought the supplies as agents for the crew rather than for resale, so the supplier's sale of the nonfood items to the owners was a taxable retail sale.

1952-09-05

Did serving California Form 465 itself demand that the recipient pay the amount the notice required the recipient to withhold?

No. The 1952 correspondence said mere service of Form 465 was not a demand for payment, although the Board could accept a voluntary payment.

1952-08-15

Did California law compel a retailer to try to collect sales-tax reimbursement from the buyer on every retail sale?

No. The source said seller and buyer could contract as they wished about the total selling price even though section 6052 contemplated purchaser funding.

1952-08-08

When could carbon dioxide sold for beverage use qualify for resale?

CO2 used solely to carbonate soda water or another sold beverage qualified; CO2 bought to push draft beer through lines was a taxable dispensing input.

1952-08-07

Did a promotional mail address and occasional agent meeting place count as a California business location?

Yes. California treated the San Francisco quarters as an office regularly used for business and required the out-of-state retailer to collect use tax.

1952-08-06

Were supplies bought by a California agency exempt when the federal government allotted the money for the purchase?

No. California treated the sales tax as imposed on the retailer and folded into the price paid by the state agency. Federal allotment of the purchase funds did not exempt the transaction.

1952-07-28

Was bookbinding equipment exempt when customers supplied the materials and the machinery also handled used books?

No for equipment used to bind new books. Initial binding was taxable fabrication requiring a seller's permit, even with customer materials; mixed-use equipment could not be excluded.

1952-07-25

Which labor was taxable when replacement neon tubing was made for an existing sign, and which labor remained repair?

Forming, evacuating, and gas-filling replacement tubing were taxable fabrication. Attaching contacts was taxable if it completed the tube, but attaching the tube to the sign was repair.

1952-07-22

Were charges taxable for printing or hand-painting textiles furnished by the customer?

Yes. Printing or hand-painting a consumer's textiles was taxable fabrication or processing of customer-furnished tangible personal property.

1952-07-11

Was an annually published regional directory an exempt thirteenth issue of the publisher's monthly trade journal?

No. California treated it as a separate publication because it had a different name, format, and size and described itself as annual.

1952-06-26

When did California require a new permit after partner changes, and could it refuse a permit for a plainly illegal sales location?

The 1952 opinion said any general-partner change created a new entity requiring Form 400 and a new permit number; adding signatures on Form 400-P was insufficient. Separate 1985 guidance said the…

1952-06-19

Did dumping rock from a barge constitute improving a breakwater rather than selling tangible personal property?

Yes only if dumping was the last act needed to place the rock. If further work remained, the dumping alone did not constitute the real-property improvement.

1952-06-18

Did a corporation need a seller's permit when its container and label sales were exempt, and how did California treat the advertising material it gave away?

Yes. The corporation had to hold a permit and report and deduct its qualifying exempt packaging sales. It could buy resale inventory ex tax with resale certificates, but it consumed the advertising…

1952-05-27

Did manufacturing loss make aluminum or spiegel-eisen taxable when the steel maker bought the material solely to incorporate it into sold steel?

No. A sole incorporation purpose supported resale treatment for the entire quantity despite waste; a separate manufacturing-aid purpose would make the full amount taxable.

1952-05-26

Was paint applied to qualifying watercraft exempt when a painting contractor, ordinarily treated as the paint's consumer, bought and applied it?

Yes. California said the exemption followed paint becoming part of qualifying watercraft, not the contractor-consumer rule. The contractor's inability to use the standard vessel-operator certificate…

1952-05-21

Did paint thinner used by steamship operators become an exempt component part of watercraft?

No. The thinner evaporated as the paint dried, so California concluded that it did not become part of the vessel. Steamship-company representatives ultimately found no basis for treating the…

1952-05-19

Were roto-blasting and unloading charges taxable for new pipe furnished by consumers as part of wrapping and coating?

Yes. Roto-blasting was an integral fabrication step in producing wrapped pipe, and unloading charges connected with the fabrication entered the taxable measure.

1952-05-16

Was Mycoban exempt food when it was sold as a bread preservative that inhibited mold?

No. California concluded that Mycoban did not appear to be a food product, so its sale to the described purchaser was taxable.

1952-05-14

Was mono-sodium glutamate exempt food when sold as a flavor intensifier?

Yes. California treated the described mono-sodium glutamate as a food product for human consumption, making its sale to the purchaser exempt.

1952-05-14

Was cement sold for federal machinery foundations taxable when the contractor immediately rebilled it and passed title to the United States?

Yes. California treated the cement as consumed in improving real property, so immediate federal title and rebilling did not exempt the sale to the contractor.

1952-05-09

Were all suits furnished through a 50-week club taxable, including weekly prize suits, and what measured the merchant's receipts?

Yes. Every suit was a taxable retail sale, but the sponsoring organization's share was treated as member contributions rather than merchant sales receipts.

1952-04-18

Could a television dealer keep the salesman's commission after rescission and still claim a returned-merchandise deduction?

No. Charging the customer the commission meant the dealer had not refunded the full selling price, so tax remained due on the television's entire $499.20 price.

1952-04-14

Were separately stated tinting charges taxable when the same photo finisher also printed the customer's pictures?

Yes when the finisher also printed or enlarged the pictures: no tinting deduction was allowed even if separately stated. Tinting customer-furnished finished pictures was nontaxable. The same letter…

1952-04-08

Which oils sold for greasing bakery pans qualified for the food-products exemption?

Vegetable-oil or lard-base products consumed as bakery ingredients were exempt, but mineral-oil products and mixtures containing beeswax or other inedible ingredients were taxable.

1952-03-24

Did Vit-A-Way Livestock Fortifier qualify as feed rather than a taxable disease-treatment product?

Yes. California classified it as feed and distinguished preventive fortification from products labeled and sold for specific disease treatment or cure.

1952-03-20

1952-03-19

Did a chassis-lubrication shop consume the lubricant included in a lump-sum service charge?

Yes, if it made no separate lubricant charge; transmission and motor oil were instead treated as sold to customers.

1952-03-19

Did U.S. Department of Agriculture funding make a contractor's materials for lump-sum real-property improvements exempt federal purchases?

No. The contractor bought the materials for its own fixed-price installation contracts, while the federal agency merely supplied part of the money. California measured tax by the contractor's…

1952-03-18

When were charges for heat-treating metal taxable, exempt for resale, or nontaxable repair?

Heat-treating consumer-owned metal was taxable processing. Work on property intended for resale was not taxable, and heat-treating used tools to repair them was nontaxable repair.

1952-03-18

Did a fertilizer seller need a California seller's permit when all current sales were for resale or exempt food-production use?

Yes. Because fertilizer retail sales could be taxable in other circumstances, the memorandum treated the person as a statutory seller and as a retailer for any retail sales, requiring a permit even…

1952-03-12

How should a swap-shop retailer value property received in exchange and document the taxable sale?

Use a good-faith bargained value or, if none was stated, the best fair-market-value estimate, supported by records of the item's description, age, condition, and comparable cash prices.
