Who owed sales tax when collectors left stamps with a stamp-and-coin shop to sell to the highest bidder?

The shop owner was the retailer because the shop possessed and controlled the consigned stamps and could sell them. Tax applied to total gross receipts, even though the shop did not own or bear loss…

1966-01-28

Were per-copy copier charges treated as paper sales when the machines required no specific paper?

No. Because the per-copy amount did not represent a transfer of tangible property, both the flat charge and the per-copy charge were rental payments.

1966-01-27

Was impregnating metal parts with Laminac resin taxable when consumers supplied the parts, and what if the treated parts were resold?

Consumer-supplied parts produced taxable fabrication charges. Processing parts furnished for resale was an exempt sale for resale, and the processor's resin purchase was also for resale.

1966-01-25

Did first racing a horse at Santa Anita make the horse subject to California use tax?

Not necessarily. Prior training could be substantial out-of-state use, and temporary racing did not create tax for qualifying owners without California stables.

1966-01-21

Did an informal plant-access arrangement count as a contract that made a retailer's prepackaged food sales at employer-provided tables taxable after section 6359 changed?

Yes. Beginning September 17, 1965, the retailer's license to sell at the plant for 4% of gross was a contract, so the amended exemption did not cover food consumed at employer-provided tables.

1966-01-14

Did paying an industrial employer 4% of gross for plant access make a food retailer's sales at employer-provided tables taxable after section 6359 changed?

Yes. The payment and plant-access arrangement constituted a contract, so beginning September 17, 1965, the amended exemption did not cover food consumed at the employer's tables.

1966-01-14

Did a bank have to collect use tax on Churchill Commemorative Crown coins bought for numismatic interest rather than ordinary use as money?

Yes. The coins were tangible personal property bought for numismatic interest, not as a medium of exchange, so the banks had to collect use tax.

1966-01-07

Were ordinary telephone and leased-line charges treated as rent for tangible property?

No. The opinion treated ordinary telephone service and leased lines for telephone or teletype service as services, while leaving an equipment-inclusive system unresolved.

1965-12-31

Did a post-closing contract amendment shifting value from tangible assets to goodwill reduce the sales-tax measure established when title passed?

No. Tax Counsel said the original allocation should remain because tax liability arose when title passed, while the later goodwill shift lacked better value evidence and apparent new consideration.

1965-12-23

Were an advertising agency's typography charges taxable when reproduction proofs were incorporated into paste-ups?

Yes. The proofs became part of taxable finished-art paste-ups. Unused proofs could be preliminary art only if separately billed and clearly identified, which the agency had not done.

1965-12-21

Could a lessor deduct taxable rental receipts that later became worthless?

Yes. The recommendation applied section 6055 to lessors that reported tax as rentals came due and charged worthless accounts off for income-tax purposes.

1965-12-21

Were an advertising agency's typography and reproduction-proof charges taxable when used in paste-ups?

Yes. Reproduction proofs incorporated into taxable finished-art paste-ups entered the full taxable charge. Proofs not incorporated could qualify as preliminary art only when separately billed and…

1965-12-21

Did tracing a rough sketch onto a separate watercolor board physically incorporate the sketch into the finished art?

No. The source said preliminary art was physically incorporated only when it was itself touched up or finished and delivered as the finished art, not when it merely supplied an outline traced onto…

1965-12-20

Could a retailer repay excess tax reimbursement by crediting it against a customer debt instead of making a cash payment?

Yes. California accepted a credit against an acknowledged preexisting debt and recommended refunding the credited $1,440 plus interest to the retailer.

1965-12-15

Did a weekly broker bulletin listing real estate offered for exchange qualify as an exempt newspaper or periodical?

No. California treated the bulletin as an advertising medium, making its $60 annual subscriptions to California brokers taxable.

1965-12-15

Did required property-tax, insurance, repair and interest charges enter the sale measure when a lessee exercised an equipment purchase option, and was the blank lease a lease in lieu of sale?

Yes on the charges. Because payment was mandatory to exercise the option, all entered sales price. No on the blank lease: nothing on its face required lease-in-lieu-of-sale treatment.

1965-12-15

Did a school photographer owe tax on prints parents kept without paying when the photographer did not pursue collection?

No for accepted but unpaid prints. Counsel found no promotional advantage from failing to receive payment or pursue collection, so their cost was not taxable as self-consumed promotional…

1965-12-14

Was monkey chow exempt when it was used to feed laboratory monkeys?

No. California said monkeys were not qualifying food animals, and their laboratory use did not change the feed-exemption test.

1965-12-07

Was a yacht bought from a U.S. Marshal under a federal admiralty-court order exempt from California use tax?

Yes. The Marshal was the retailer and an unincorporated federal instrumentality, and section 6402 did not require the Marshal to own the yacht. The judicial liquidation was not conducting a taxable…

1965-12-02

Did an oil refinery's provision of some eating facilities make a retailer's bulk insulated-container food sales taxable under the 1965 section 6359 amendment?

No, not on that fact alone. Tax counsel treated the arrangement as a straight bulk sale because the necessary proximity and agreement linking the seller to the eating facilities were absent.

1965-11-29

Was equipment used to make nonreturnable molded-pulp food containers outside a permit-requiring activity because many container sales were for resale?

No. Retail container sales were taxable, and resale treatment depended on how buyers used them rather than an exemption for all containers. Selling them required a permit, so the equipment sale was…

1965-11-29

Was a driving-range charge taxable rent merely because it was based on the number of golf balls used?

No. Ball-count pricing was a charge to use the range, not taxable ball rent; the range consumed the balls and its retailers made taxable sales.

1965-11-29

Does sales tax apply when a Christmas tree farm charges consumers to choose, cut, and remove their own trees?

Yes. The letter treated choose-and-cut Christmas tree transactions as retail sales of tangible personal property subject to sales tax.

1965-11-22

Was an out-of-state correspondence school the consumer or retailer of books and lesson materials furnished to California students?

It was the retailer because students, not the school, used the regularly furnished books and materials. The school had to register and collect use tax on their fair retail selling price.

1965-11-19

What proof kept a yacht broker from being treated as the retailer after signing a conditional sales contract as seller?

A retained writing showing that the owner accepted the buyer's offer before the broker signed the contract established a true brokerage. Without that proof, the listing could be read as giving the…

1965-11-19

Were modular radio-frequency anechoic chambers bolted together and to a building floor machinery and equipment?

No. They were materials because they were not readily removable as units, and providing a room for manufacturing did not make the room itself manufacturing machinery.

1965-11-12

How did California tax race-horse and stud-stallion syndicate shares?

Each share transferred an undivided ownership interest in tangible personal property. California-located horse shares were subject to sales tax; an out-of-state sale could create use tax if the…

1965-11-12

Were receipts for designing and building temporary tooling taxable when the customer used it to make test objects before deciding whether to order a permanent model?

No. California treated the contract as engineering and design services that conveyed information; the vendor consumed the materials used in the temporary tooling.

1965-11-10

Were full custom-portrait invoice amounts taxable when customers paid deposits but later refused C.O.D. delivery of the finished prints?

Yes. The special-order sales were completed, so full invoice amounts were gross receipts, with a bad-debt deduction for unpaid balances.

1965-11-10

Were refused C.O.D. portrait prints still taxable sales, and could the unpaid balance be a bad debt?

Yes. The custom order, invoice, and retained down payment consummated the sale; full invoiced receipts were taxable and the unpaid balance was deductible as bad debt.

1965-11-10

Did monthly Bechtel Briefs qualify as an exempt periodical, and were a commercial artist's reproduction-art charges also exempt?

The publication qualified, but the artist's charges for layouts, designs, photographs, lettering, and other reproduction artwork remained taxable.

1965-11-08

Could a permitted boat-and-trailer seller buy registrable trailers tax-free for resale without holding a DMV dealer license?

Yes. A valid seller's permit allowed ex-tax trailer purchases for resale even though the trailers required registration and the reseller was not DMV-licensed.

1965-11-03

Were out-of-state printed railroad tariff correction supplements distributed at least every three months exempt from California use tax?

Yes. California treated the recurring correction pages as periodicals under former section 6362, so their in-state distribution was use-tax exempt.

1965-11-01

Were per-unit royalties taxable when an inventor sold one log peeler and retained usage rights in another peeler leased by a different owner?

Yes. The inventor's retained control and compensation rights were ownership interests, making sale and lease royalties taxable receipts.

1965-11-01

Were rentals taxable when a lessor built storage tanks from steel and fittings it bought tax-paid?

Yes. The opinion treated the rental charges as taxable because the fabricated tanks were not leased in substantially the same form as the steel and fittings acquired.

1965-10-21

Were payments for battered ends or irrecoverable sheets taxable receipts when tax-paid steel piling was leased in the same form as bought?

No on the stated terms. They were damages, not sale receipts; the lessee could not retain usable material or benefit from damaged or unrecoverable piling.

1965-10-21

Could a seller prove contractor resales without certificates or purchaser permits?

Yes, through evidence showing resale in the purchaser's regular business; isolated invoices and no permit were insufficient, but substantial contractor facts could meet the burden.

1965-10-06

Did collecting California use tax for seven years without filing returns or paying the state establish fraud?

Yes. Counsel found clear and convincing evidence of intent to evade where the seller billed and collected California use tax for seven years but remitted none of it.

1965-10-06

Did out-of-state delivery or continued interstate use prevent tax on rent while leased equipment was in California?

No. The opinion treated the lease as a continuing California sale while the equipment was in the state and applied sales tax to the rent even if use tax did not apply.

1965-10-05

When could separately charged operator or maintenance services be excluded from taxable equipment rent?

When they were optional. Mandatory maintenance entered taxable lease receipts, while optional operator or maintenance services could be excluded if separately charged.

1965-10-05

How were boat rentals taxed when a purchaser acquired a marina and its boats in an exempt transaction?

Boat rent was taxable. Because the marina purchase was exempt under section 6281, the buyer could not elect acquisition tax instead.

1965-10-05

Were optional contributions from recipients of a charity's large-type children's books taxable retail-sale receipts?

No. Recipients could receive books without paying, so the charity was the consumer and voluntary contributions were not retail-sale receipts.

1965-10-04

Were promotional materials sold to retailers for free distribution to their customers taxable retail sales?

Yes. The source treated the purchasing retailers as consumers of ordinary promotional material they gave away, making the seller's California sales taxable retail sales.

1965-09-27

Was a country club's automatic 15% service charge a nontaxable gratuity when the club passed it to employees without using it to offset wages?

No. Because every member was obligated to pay the fixed, automatic charge, tax counsel classified it as an exaction and taxable meal-sale receipt even though employees received it.

1965-09-24

Were year-end alterations to customer-owned tools and dies taxable when automobile model changes required them to produce a new item?

Yes. The model-change alterations were taxable fabrication because they enabled production of a new item and went beyond repair or reconditioning.

1965-09-22

Were advertising circulars exempt when some were inserted into newspapers and others were distributed separately by mail and hand?

Only the newspaper-inserted circulars were exempt components. Separately distributed circulars were taxable retail sales.

1965-09-22

Did converting a piston aircraft to a jet create a newly manufactured aircraft, or was it repair or modification of the existing plane?

The conversion did not manufacture a new aircraft. It was repair, reconditioning, or modification, with tax applying to the parts, materials, and equipment used.

1965-09-21

Could a buyer exclude amounts labeled severance costs or going-concern value from the price of tangible personal property?

No under the described sale. Severance costs were seller expenses and agreed going-concern value was part of the amount paid.

1965-09-15

Why did California enact the provision addressed in Annotation 495.0680 after adopting the Uniform Commercial Code?

To prevent arguments that the Commercial Code moved a sale away from the property's physical location; the Board expected no practical tax change.

1965-09-10

Did a restaurant fixture sale occur when buyers deposited part of the price, took possession, and operated for a month before abandoning the deal?

Yes. Counsel applied section 6006 to the escrow deposit, balance promise, possession, and operation, then recommended denying redetermination. The live annotation says the deposit was $10,000; no…

1965-09-10

Was returning business assets to the original seller under a rescission or repossession agreement a second taxable sale?

No. The return was either cancellation of the original sale or exercise of a repossession right, not a second sale.

1965-09-08

Could a lumber retailer exclude later bills for sorting at a tract compound and delivering selected lumber to individual home sites?

No. The retailer's sale was the lumber furnished at each jobsite, so the later sorting and compound-to-site delivery charges remained in gross receipts.

1965-09-03

Were diagnostic opaques and dyes exempt medicines when administered internally for X-ray examinations?

Yes. California treated the contrast substances as medicines because doctors and hospitals applied them internally to diagnose disease through X-ray imaging.

1965-09-01

Were both first-year and renewal fees taxable when a purchasing service sold merchandise to members at wholesale prices?

Yes. Both fee types were sufficiently connected to anticipated retail sales, and renewals were not materially different from initial memberships.

1965-09-01

Did The Delcon Detector, issued at least quarterly with articles on ultrasonic leak-detection technology, qualify as an exempt periodical?

Yes. California treated the at-least-quarterly technical publication as an exempt periodical under former section 6362 and Ruling 50.

1965-08-31

Were large bronze fountain sculptures fixtures or construction materials?

They were materials because they were designed and installed as integral parts of concrete fountains, welded to embedded framing and sometimes connected to the water supply.

1965-08-31

Was placing reinforcing steel into horizontal tilt-up wall forms taxable fabrication?

Yes on the limited facts first presented, because the slabs had not reached their final position. A later opinion using fuller facts held the steel contractor was a construction contractor.

1965-08-30

Did monthly issues of The Prune Picker, containing S Association member, officer, meeting, and activity news, qualify as a periodical?

Yes under the 1965 analysis. California treated the monthly member newsletter as an exempt periodical and its printing charges as exempt.

1965-08-27

Should a lessor collect tax when late rent arrives after the lessee says it already paid the tax directly?

Not if the lessee sufficiently shows that tax on that specific late payment was already reported and paid. Otherwise, the lessor remained liable and should collect it.

1965-08-25

Did the historical ice exemption cover liquid nitrogen sold to cool food products shipped out of state?

No. Assistant Counsel read former section 6359.5's specific terms `ice` and `dry ice` as excluding liquid nitrogen, even when a trucker used it to cool human-consumption food shipped outside…
