Were California retail sales of coins and stamps as collectors' items subject to sales tax?
Yes. The source treated collectible coins and stamps as taxable tangible personal property and said a person selling them in business needed a seller's permit.
Who was the consumer of a bronze niche panel's first engraving: the cemetery or the person acquiring the niche-use right?
The cemetery was the consumer, so the engraver's charge to it was taxable. Passing the charge to the niche user was not another taxable sale because the panel remained cemetery realty.
Did a contractor erecting a California hospital consume the window materials incorporated into the building?
Yes. The contractor consumed the incorporated window materials, so their purchase was subject to sales or use tax depending on whether interstate-commerce rules exempted the sale.
Did Silogerm qualify as animal feed even though its bacilli were not themselves nutrients?
Yes. California analogized Silogerm to bread yeast because its lactic acid improved silage digestion, reduced spoilage, and increased milk production.
What price measured tax when a California supplier delivered property for an unregistered out-of-state retailer to a California customer?
The out-of-state retailer's price to the California consumer measured tax, not the supplier's wholesale charge; a resale certificate applied if the recipient resold the property.
Was an automobile dealer's transfer of one-third of its assets to each of two shareholders tax-exempt when they surrendered their stock but the corporation continued?
No. The memorandum treated the exchanges as taxable because the corporation did not completely dissolve and there was no positive evidence that the surrendered stock was retired.
Was an automobile dealer's transfer of branch assets to two shareholders for their one-third stock interests an exempt partial liquidation?
No. The January 25 memorandum treated two one-third asset-for-stock exchanges as taxable because the automobile corporation remained with its third shareholder, made no entire dissolution or…
Were Red Books exempt periodicals when they were classified advertising directories with mileage, nutrition, postal-zone, and street-guide features?
No. California treated them as taxable advertising directories, and the added tables, maps, and guides did not change that classification.
Could a photographer deduct separately charged travel and meal expenses from the taxable sale price of a photograph?
No. The supporting letter treated customer-paid travel, meals, and other business expenses as part of the photograph's sale price and applied tax to the entire amount.
Were charges taxable for perforating casing owned by the customer?
Yes, assuming the customer consumed the casing. Perforating was producing, fabricating, or processing under the cited ruling.
Was undersealing taxable when applied to a customer's used car versus a dealer's car held for sale?
Used-car undersealing was repair and the applicator consumed the material; dealer undercoating before sale remained part of the taxable car price.
Were charges and incorporated chemicals taxable when a business coated exempt seed beans?
No. Treating exempt seed was nontaxable, and chemicals incorporated into the seed could be bought for resale, whether the farmer or treater supplied the beans.
Was a corporation's transfer of property to a minority shareholder for shares held as treasury stock a sale or a dissolution distribution?
It was a sale, not a dissolution distribution. Tax applied unless the property qualified for the narrower occasional-sale exemption under section 6006.5(a).
Was a second engraving taxable on a double urn that was tangible personal property and had been used for a considerable time?
No. The second engraving was performed on used merchandise, and the Board's stated general policy did not tax engraving of used property.
Was a pipe vendor reselling lumber used to block pipe safely in railroad cars when it did not separately bill customers for the lumber?
No. Tax Counsel treated the pipe vendor as consumer because it bought lumber to prepare its products for safe railroad shipment and did not specifically bill customers for the blocking material.…
Were five nutritional products exempt when sold to feed mixers for compounded animal and poultry feed?
Yes. California treated Vitamin D3, Vitamin B-12, Baciferm, Dupont's Two-Sixty-Two Feed Compound, and BY-500 as animal feed.
When were animal vitamins treated as exempt feed rather than taxable drugs?
Vitamins mixed into feed for normal nutrition were feed; dosage-form products used to overcome a specific deficiency were drugs.
Which named supplements were animal feed, and which products were taxable drugs?
APF 5, APF-1G, Fortafeed, Choline Chloride, Niacin, Calcium Pantothenate, and Parvo were feed; Megasul and Enheptin were drugs.
Was an automobile partly exempt when an eligible veteran selected and received it but the Veterans Administration paid $1,600 directly to the dealer?
Yes, to the extent of the amount billed to and paid directly by the Veterans Administration. California recommended showing the VA as purchaser for that share; the veteran's share was not treated as…
Were vitamin pills taxable when an employee organization included them as part of an otherwise exempt meal sold to employees?
No, if the meal qualified for the cited employee-meal exemption and the pills were sold as part of it. Pills sold separately remained taxable because section 6359 excluded them from food products.
Could an automobile dealer exclude a stated trade-in “overallowance” from taxable gross receipts by calling it a discount?
No. Because the invoice tied the overallowance to the used car, counsel treated it as part of the agreed trade-in allowance unless it was a genuine discount available without a trade-in.
Did assumed exclusive newspaper use make a printing-press sale occasional when the publisher made several equipment sales?
No. Staff treated three or possibly four sales totaling $12,684 in less than four months as a permit-requiring series and would not recommend approving the press-sale refund claim.
Could a combination mattress law tag and shipping-container production ticket receive a partial sales-tax exemption?
No. The shipping-container section was a taxable shipping tag, and California found no basis to exempt any part of the full sales price.
Were window frames and screens materials sold to contractor-consumers, and how did vendors show tax reimbursement?
They were materials sold to contractor-consumers. A vendor that did not install them had to separately show included sales-tax reimbursement on bids and invoices.
Did a print become an exempt interstate sale when the customer picked it up at the seller's California plant and later returned it for outside shipment?
No. Pickup completed the California sale; a later customer return and seller shipment outside the state did not change that completed transaction.
Was paint used to recondition returnable oil and grease drums exempt as a replacement label?
No. California taxed ordinary reconditioning paint, but said new decals and paint used for stenciling could qualify as labels replaced at each filling.
Could a retailer issue a full return credit, then bill the customer for delivery, use, or rent, and still claim a returned-merchandise deduction?
No. The follow-up charge meant the customer did not receive the full sale price in substance, regardless of whether the bill was labeled delivery, use, or rent.
Could a taxpayer deduct quilting charges from gross receipts as nontaxable labor?
No. Based on the limited facts, quilting was a step in producing, fabricating, or processing tangible personal property, so the charges remained in gross receipts.
Was purifying used welding flux nontaxable reconditioning when customers received their identical material back?
Yes. Returning the same purified flux was a service; commingling customers' flux and returning nonidentical material made the full charge taxable.
Did a 1951 California letter apply the diagnostic x-ray producer rule to industrial radiographs used to inspect metals?
No. The letter limited the rule to diagnosis of human-body conditions. A laboratory furnishing industrial radiographs was a taxable retailer, while an inspection service transferring no title to…
Could parties avoid federal construction-contract tax by splitting one real-property job into separate material-sale and installation contracts?
Not when they intended from the start that the supplier would install the materials. California treated the essential overall transaction as a real-property contract.
Was excess city sales-tax reimbursement retained on sales outside city limits part of state-taxable gross receipts?
Yes. Only tax actually imposed by the city could be excluded; the extra amount mistakenly charged and retained was taxable gross receipts.
Were charges taxable for cutting slots in pipe owned by the customer despite an older pre-1939 court decision?
Yes. The 1939 statutory amendment added processing of consumer-furnished property to the definition of sale, so pipe slotting was taxable under the later law.
Was a printed garment-guarantee notice enclosed with the product purchased for resale or consumed as advertising?
A genuine guarantee notice delivered with the garment was purchased for resale, but primarily advertising material was consumed by the manufacturer. The source could not classify the actual notice…
Did guest consumption defeat the student-and-teacher meal exemption when club members were charged for and paid for their guests' meals?
No. The memorandum treated the meals as sold to the paying members rather than the guests and applied the student-and-teacher meal exemption, allowing the refund claim to proceed.
Were protective covers, including searchlight covers, exempt component parts of commercial deep-sea fishing vessels?
No, on the described use. California treated the covers as consumable protective items rather than integral vessel parts substantially attached while in use. A searchlight cover had to be removed…
Was yeast exempt when sold for use as poultry feed?
Yes. California treated yeast sold for use as poultry feed as exempt under Ruling 47 as then cited.
Did B Y-21 qualify as exempt feed when mixed into poultry and animal feed?
Yes. California treated the grain-fermentation product as feed because it supplied riboflavin and other nutrients to compounded feed.
How did California historically count a city's sales, determine permit locations, and treat transfers between city departments?
It aggregated department sales, generally used one in-city permit plus permits for outside locations, and treated internal transfers as nonsales.
Were a photographer's full architectural charges and photographs sold for magazine reproduction taxable?
Yes. California allowed no expense deduction and treated reproduced photographs as taxable because the physical photographs did not enter the magazine.
What averaging period determined whether a boardinghouse served five or more paying guests under the cited rule?
No fixed monthly or annual period applied. The memorandum required a reasonable fact-specific period, recognized permanent operational changes sooner than ordinary business declines, and did not…
Were mail chutes fixtures, and could a supplier accept resale certificates from contractor-retailers?
Yes. Mail chutes were fixtures, so sales to permitted contractors could be for resale, although contractors could instead buy them tax-paid.
Did California tax repainting a removable sign when its copy changed?
Yes. The 1951 opinion treated the repainted removable sign as a new sign and taxed the seller's full gross receipts.
Was repainting a removable sign to change its copy taxable, and how did California distinguish building and automobile lettering?
Repainting a removable sign with new copy was taxable because it created an essentially new sign. Building and automobile lettering were treated as services with materials consumed by the letterer.
Were materials and supplies for an automatic sprinkler system at a United States military base exempt government purchases?
No. California treated the sprinkler system as a real-property improvement and taxed the materials and supplies sold to the installation contractor.
Did naming the purchaser instead of the seller as consignor on a bill of lading make an otherwise interstate shipment taxable?
Not by itself. The sale could remain exempt if the contract required the seller to deliver the goods to a carrier for out-of-state shipment and the goods were actually delivered and shipped that way.
Was a corporation's transfer of furniture and fixtures to a shareholder in exchange for retiring the shareholder's stock taxable?
Yes. The August 14 correspondence treated a corporation's furniture-and-fixtures transfer to one stockholder for that holder's retired stock as taxable, measured by the stock's value. The live…
Could mimeographed club papers qualify as exempt newspapers even though they were not produced by a traditional typesetting process?
Yes. California found no sales-tax rule barring mimeographed publications that conveyed news and opinions at stated intervals and met Ruling 50.
Were peat moss and peat humus exempt fertilizer when used to grow food-producing plants?
No. California classified both products as soil amendments rather than fertilizer, making their retail sales taxable even for food-producing plants.
Was converting a transport loader from hydraulic to mechanical operation taxable fabrication or repair?
Fabrication for a new loader; repair for a customer-furnished used loader, with tax on segregated parts or the entire unsegregated charge.
Could a seller deduct a book reserve for disputed federal amusement tax that had not been reported or paid?
No. The historical deduction covered federal amusement tax actually paid, not an unpaid contingent reserve while liability remained in litigation.
Did a press-clipping bureau sell tangible clippings when it monitored publications for subscribers and charged per clipping?
No. California treated the subscriber agreement as a service contract, and unit pricing based on the number of clippings did not make the receipts taxable sales.
Was trophy engraving taxable for the first inscription and for later winner names added after the trophy had been used?
The initial engraving was taxable work on new merchandise. Later names added after the trophy had been exhibited or used were engraving on used merchandise and were not taxable.
Did Service Notes qualify as an exempt periodical when model changes, rather than a regular schedule, determined when instructions were issued?
Apparently not. California found the stated irregular schedule insufficient but invited a sample and additional facts for further review.
Did California use tax apply to caskets, urns, or other funeral property supplied out of state when burial occurred in California?
Yes. California burial was a taxable use regardless of where death or preparation occurred, subject to collection and federal-purchaser exceptions.
Did merchandise become exempt when a county or local agency paid with federal grant funds?
No. California said the sale was to the local agency, not the United States. Federal funding did not change the purchaser, and the retailer's sales tax remained part of the price paid by the local buyer.
Did brine inhibitor used in a vessel's affixed refrigeration system qualify as an exempt component part?
Yes, if used as described. The inhibitor remained in the refrigeration plant's freezing coils and needed replenishment only to maintain freezing quality, distinguishing it from consumable fuel and…
Did reducing the number of trustees in a business trust create a new entity requiring a new seller's permit?
No. The 1951 opinion treated the business trust as an entity separate from its trustees, so reducing the number of trustees did not require a new permit where the application and permit named the…
How did California distinguish taxable rug fabrication from wall-to-wall carpet installation?
Binding, serging, and sewing that fabricated a rug were taxable, but the same work incidental to installation was installation labor; wall-to-wall carpet contracts used consumer-material treatment.
Were steel slitting and shearing charges taxable when included in a retail sale and when customers supplied their own metal?
Yes. Seller-performed slitting or shearing was part of taxable gross receipts, and contract processing of consumer-furnished steel was taxable under the cited ruling.
