Did Monthly Review, 12-L News, and its Lumber Industry supplement qualify under California's historical periodical exemption?
Monthly Review qualified; 12-L News did on a monthly-frequency assumption; the supplement depended on regular issuance at least every third issue.
Were a bookbinder's affixed machinery and equipment taxable when sold with a lease assignment, and could the transaction qualify as an occasional sale?
The letter said trade fixtures or equipment subject to continuing removal rights were personal property. It also questioned occasional-sale treatment because bookbinding required a seller's permit.
Did the bimonthly Market Basket News qualify for California's historical periodical exemption?
Yes. The supporting opinion exempts the submitted bimonthly Market Basket News under former section 6362.
Were charges taxable for lacquering new film and for lacquering old film that had become scratched or worn?
Lacquering new film was taxable processing. Lacquering old scratched or worn film was nontaxable repair, though the service provider consumed the lacquer and other materials.
Were charges to lacquer new film and worn used film treated the same for California sales tax?
No. Lacquering new film was taxable processing; lacquering scratched or worn used film was nontaxable repair or reconditioning.
Was an employer a reseller of safety glasses when employees paid only 15% of the employer's cost?
No. The employee charge was too nominal to establish a retail resale, so the employer was treated as the consumer of the glasses.
Could chewing gum be treated as part of an exempt meal so that its selling price escaped sales tax?
No. The memorandum said chewing gum was not properly part of a meal for that purpose, leaving the seller liable for sales tax on the gum's selling price.
Was handcarving or decorating a gun stock taxable when performed on a new gun and on a used gun?
Work on a new gun was taxable as a continuation of manufacturing to meet the customer's requirements. Similar alteration or decoration of a used gun was not taxable processing.
Were charges taxable for mounting transparencies in cardboard, and could separately stated developing charges be excluded?
Mounting transparencies was taxable fabrication. Developing alone was nontaxable only when its charge was separately stated from the mounting work.
Which charges were taxable when a business fabricated and installed a replacement covering on an automobile top?
Tax applied to the fabricated replacement top, including sewing and cutting labor, but not to the labor of installing it on the automobile.
Were sales of Karakul sheep exempt even though the breed was used heavily for wool production?
Yes. California kept Karakul sheep within the food-animal exemption because the breed was definitely used for food despite its greater wool use.
Was equipment transferred by partners to a newly formed partnership subject to sales tax?
No sales tax applied under this internal guidance when a partner contributed property as venture or partnership capital. A property sale to the entity for cash or other consideration not…
When did a manufacturer's below-cost transfer of advertising materials count as a resale rather than its own taxable consumption?
A gift or nominal charge made the manufacturer the consumer, but a bona fide substantial sales price established a resale taxed on that retail price unless it was a sham.
When was a printed product enclosure resold with the goods rather than consumed as advertising?
The source looked to primary purpose. Desired directions, instructions, stories, or other consumer information could be resold with the product despite incidental advertising; an enclosure primarily…
Were folders enclosed with dolls resale items or taxable advertising materials?
Story or verse folders could be resale items because buyers valued them, but folders listing only other dolls were taxable advertising consumed by the seller.
Did a product's label control whether it was exempt feed or taxable medicine?
No. California said actual product character controlled; an exaggerated medicinal label could not replace review of how the product functioned.
When did adding drugs or nonnutritive ingredients preserve or defeat feed status?
Preventive or disease-control fortification remained feed; a mixture labeled and sold for specific treatment or cure was not feed.
Who consumed parts under separately sold second- and third-year television warranties assigned to a service company?
The assignee service company did. By assuming the warranty seller's obligations, it owed tax measured by its cost of parts and materials furnished under the contracts.
Were charges taxable for made-to-order drapes and for adding a row of shirring to new or used drapes?
Made-to-order drapes and shirring new drapes were fully taxable fabrication. Shirring used drapes could instead be repair or reconditioning under the cited repair ruling.
Was a vendor's one-time sale of vending machines taxable after it supplied merchandise for resale to a military post exchange?
Yes, if the vendor supplied nonexempt merchandise to the exchange. Those wholesale sales required a seller's permit, so its equipment sale was taxable even if made only once.
Did the difference between cost and a bona fide below-cost price for advertising materials become an additional taxable amount?
No. Tax followed the genuine selling price, unless the stated price was fictitious and concealed other consideration or was part of a sham designed to evade tax.
Did severe accident damage before a car entered California reduce the use-tax measure?
No. Use tax remained measured by the full purchase price even though the Cadillac needed $2,000 of repairs when it reached California.
Was California-use intent measured when a car was ordered or when the buyer later acquired title, normally at delivery?
At acquisition of title, normally delivery. Because the buyer then knew the Illinois car would be used in California, use tax was due.
Did subcontracting a repair make the retailer's full customer charge taxable?
No, if parts and materials were segregated from repair labor; otherwise California presumed the full charge was taxable property.
Were charges taxable for planing and ripping lumber furnished by consumers, and what if the finished lumber would be resold?
Consumer-furnished lumber produced taxable processing charges. Work on lumber furnished for resale was not taxable if the processor obtained resale certificates.
Was a heavy printing press returned when the failed buyer kept physical possession but stored it solely for the seller after rescission?
Yes, potentially. Physical repossession was unnecessary if the sale was timely rescinded, the buyer thereafter stored the press for the seller, and no valid consideration was received.
Did a monthly publication covering all public transportation serving San Francisco qualify as an exempt periodical?
Yes. California exempted the submitted monthly transit publication and referred the requester's prior-tax refund claim for processing.
Which refrigeration-system components were fixtures and which were materials under the 1951 opinion?
Compressors, condensing units, and the evaporative condenser were fixtures; built-in walk-in boxes and tubing in conduits or concrete were materials.
When were school supplies furnished to student-veterans exempt as Veterans Administration purchases?
Only when the VA actually purchased and paid for the supplies, or when a school validly bought for resale and then sold them to the VA. Supplies invoiced to students were taxable when the VA merely…
Did zinc electrodes used in an affixed vessel water-cooling system become exempt watercraft component parts?
Yes. California treated zinc electrodes used in a water-cooling system affixed to the vessel as component parts. The letter applied the same approach to replaceable filter elements for substantially…
Did taxability of a vessel component depend on the vessel's activity at the exact time of sale or on its principal use?
Principal use controlled. A mixed-use vessel could qualify when its principal use was transportation for hire in interstate or foreign commerce, even if it also made intrastate voyages. Principal…
Was a dentist a retailer of plates and inlays made in the dentist's own laboratory for use in patient services?
No. The dentist was the consumer of the materials used to make dental-laboratory products that the dentist then used in performing professional services.
Were tank-calibration charges taxable when the customer received a written report, and what if the work produced a gauge stick or monthly oil-field map?
Calibration with a written report was not taxable; producing a gauge stick was taxable, and monthly oil-field maps did not qualify as exempt periodicals.
Did replacement refrigerant gas in a system affixed to qualifying watercraft become an exempt component part?
Yes. California treated replacement refrigerant in an affixed vessel system as becoming part of the watercraft, provided the vessel also met section 6368's qualifying transportation-for-hire or…
How did California's historical tax measure differ for fixtures fabricated under federal and private construction contracts?
For federal work, California taxed the contractor's purchase of materials or fixtures; for fabricated fixtures, the raw-material sale price replaced the fair retail value used for private work.
Did rebuilding a pleasure-boat cabin into a larger cabin with sleeping space fabricate a new vessel?
No, provided the vessel remained a pleasure boat. The work was repair or reconditioning, so tax applied only to the parts and materials used.
Was rebuilding and enlarging a pleasure-boat cabin taxable fabrication of a new vessel?
No. Because the vessel remained a pleasure boat, California treated the enlarged cabin and added sleeping facilities as repair, taxable only on parts and materials.
Could a shipper treat packing-list envelopes enclosed with merchandise as exempt containers?
No. Associate Tax Counsel treated the shipper as consumer of both the packing list enclosed with merchandise and its envelope, so former Ruling 49 did not exempt the printer's envelope sale. The…
What did principal use mean when a commercial fishing boat operated both inside and outside California territorial waters?
It meant actual operating time. To qualify, fishing operations outside California territorial waters had to exceed 50 percent of the boat's total operating time. Principal operation inside state…
Were charges taxable for duplicating form letters with Robotyper or other mass-production methods?
Yes. California treated mass-produced duplicated letters like mimeographing, multigraphing, or printing rather than personal typing services.
Were charges for mass-producing duplicated form letters on Robotyper machines taxable?
Yes. California treated the process like mimeographing or multigraphing: a form of printing rather than predominantly personal typing service.
Was converting a chassis and propane tank into a complete tank truck taxable fabrication or repair and installation?
With a new chassis, the full conversion charge was taxable fabrication. With used equipment, fabricated parts and materials were taxable but installation labor was not.
Were separately stated television, antenna, and washing-machine installation or post-sale service charges taxable?
No for genuine installation and post-sale services, but antenna fabrication remained taxable and could not be relabeled as installation labor.
Could a medicated poultry product be partly taxable based on its nonfeed ingredients?
No. California classified the whole product by its primary purpose and taxed it entirely because it was sold mainly as a one-day vermicide.
Were charges taxable for tanning consumer-owned hides and for manufacturing gloves from customer-furnished leather?
Yes. Tanning was a production step, and making gloves from consumer-furnished leather was taxable producing, fabricating, or processing.
Was a car bought for California use when the purchaser's employment transfer was still being negotiated on the purchase date?
It depended on what he knew or anticipated that day. The letter sought a signed statement before deciding whether to withdraw the tax claim.
Were charges to purify customers' used transformer oil or paint thinner taxable when the material was returned?
No, if customer lots were not commingled and the same material was returned; the charge was taxable if customers received nonidentical material.
Was a California-side store sale exempt when a Mexican resident picked up the goods, crossed the border and obtained an export declaration?
No. California store delivery preceded any export journey. Later purchaser transport and an export declaration did not change the taxable sequence.
Were retail sales of pocketbooks exempt as newspapers or periodicals?
No. California treated pocketbooks as taxable retail merchandise, not newspapers or periodicals.
How did California tax lettering new versus used luggage and related sign-painting work?
Lettering new luggage was taxable, but lettering used luggage and repainting used signs were not. Work on building signs and in-place mailboxes was also nontaxable.
Did California sales tax apply to charges for lettering signs on new or used trucks and automobiles?
No. Charges for lettering signs on new or used trucks and automobiles were nontaxable, and the sign painter consumed the paint used for that work.
Could a federal contractor issue resale certificates when title to merchandise passed to the United States upon acquisition?
Yes, for property bought for resale to the government. But California required tax on property the contractor used to improve real property.
Were direction finders, radiotelephones, automatic pilots, and depth sounders exempt components of qualifying fishing vessels?
Yes, when substantially affixed or attached to qualifying watercraft while in use. California treated portable navigation or communication equipment differently: if it remained portable rather than…
Could a retailer deduct a December discount calculated as 2.5% of the customer's January-November purchases?
Yes. The Board treated the described Christmas Club allowance as a trade discount for a selected customer class and permitted a documented return deduction.
Could a nursery buy stakes, ties, and fasteners for resale because they later accompanied the trees sold?
No. Their use supporting trees in the nursery made them taxable production supplies, while root-wrapping material and qualifying labels received different treatment.
Which nursery supplies were taxable when avocado trees were grown and sold with supports, root wrapping, and labels?
Stakes, ties, and fasteners were taxable production supplies. Burlap and twine wrapped around roots at sale were exempt container materials.
Could the drug-store retailer use the grocery-store percentage method to compute tax on its food sales?
No. The grocery-store alternate method did not apply to the drug store's food sales, so the retailer needed records supporting its claimed food exemptions.
How did California treat materials used by dental laboratories to repair or reline dentures when the laboratory made one lump-sum charge?
The laboratory was the consumer of insignificant materials not separately charged to the customer, so tax applied to the laboratory's cost of those materials.
Were a printer's later wrapping and packing charges taxable when completed merchandise was held for future delivery?
Usually yes because title likely passed at shipment; if title had already passed and the printer held goods only as bailee, later service was nontaxable except packing materials.
How did California tax a state institution's sales of food, feed, animal products, scrap, containers, blood, livestock, and transfers to other state agencies?
The 1950 opinion treated retail sales as taxable unless a food, qualifying animal-feed, resale, or nonreturnable-container exemption applied, but said transfers between California state agencies…
