Could a corporate trust beneficiary use the trust's Personal Income Tax Law exclusions and capital-gain percentages on its California franchise-tax return?
No. Although the fiduciary correctly excluded U.S. bond interest and applied former section 18151 percentages on the trust's Personal Income Tax Law return, the corporate beneficiary was governed by…
Was interest paid on federal tax deficiencies subject to California's historical corporate interest-deduction limitations?
Yes. The ruling treated deficiency interest as compensation for retaining money that should have been paid to the government, economically similar to borrowing. It therefore applied former section…
Were royalties paid to a nonresident for an exclusive territorial license to conduct copyrighted courses in California California-source income?
No. The historical ruling treated the payments as copyright royalties but found that granting an exclusive right to use the courses in a California area did not localize the copyright or give it a…
Did a foreign corporation begin doing business in California when it negotiated, contracted for, and financed a local plant to process products it would sell?
Yes. The California negotiations, signed plant contract, construction loan, corporate qualification, start of construction, machinery delivery, and funded bank account formed the first steps of an…
Was a liquidating corporation still doing business when it sold its hotel for interest-bearing notes and collected interest during the wind-down?
Yes. Ordinary wind-down acts such as paying debts, collecting noninterest-bearing receivables, and pursuing refunds generally lacked a profit purpose. But this corporation converted its principal…
Was the federal tax savings retained by a parent under a consolidated-return tax-sharing agreement dividend income eligible for the historical dividend deduction?
Yes. Subsidiaries paid the parent their separately computed federal tax while the parent paid the lower consolidated liability and kept the difference. The ruling treated that retained amount as a…
Was a withdrawn but undissolved Nevada corporation still doing business in California when its Los Angeles office only pursued federal refunds and wound up affairs?
No. The corporation had sold all operating assets, earned no post-withdrawal income, and retained only bank deposits and federal refund claims. Its Los Angeles staff merely pursued those claims and…
Did a Nevada corporation continue doing business in California after withdrawal when its remaining office only pursued tax refunds and wound up affairs?
No. The corporation had sold all operating assets, retained only bank deposits and federal refund claims, and earned no post-withdrawal income. Its Los Angeles staff merely prosecuted the refund…
Could a subsidiary's time-barred overpayment be credited against later combined-basis taxes owed by the unitary parent-subsidiary group?
No. Recomputing the parent and subsidiary on a combined basis did not erase the separate-return limitations periods. Former section 26073 applied regardless of why the overpayment arose. Because the…
How should a battery retailer split a $10 guarantee allowance when the failed battery still had $1 of junk value?
Treat $9 as the defect allowance and $1 as taxable trade-in value—or deduct $10 for the defect and add the $1 trade-in value to the replacement sale.
Was a payment to cancel a nonresident's personal-service contract California-source income when all contracted services had to be performed in Hollywood?
Yes. The ruling treated the cancellation payment as a substitute for future compensation under a contract requiring all services in Hollywood, not as gain from an intangible contract right. Payment…
Was consideration paid to a nonresident for a ten-year covenant not to compete in California California-source income when included in a stock sale?
It depended on whether the noncompete consideration could be separated from the stock-sale price. A severable amount paid for the ten-year promise not to compete in California was California-source…
Did a common parent's federal limitations waiver also extend California assessment and refund periods for a subsidiary included in consolidated federal returns?
Yes. By joining the consolidated federal returns and authorizing the common parent to act, the subsidiary was treated under federal regulations as agreeing through its parent-agent. The parent's…
Did a newly formed land-development corporation begin doing business before signing a final land contract or opening escrow?
Yes. The historical definition covered actively engaging in a transaction for financial gain, and 'transaction' was broader than a completed contract. Because acquiring land was integral to the…
Did an airline lose the aircraft exemption when a financing third party held title to the engines and propellers and leased them to the airline?
No. The third party held title for financing, while the airline had the complete aircraft, beneficial ownership, and an option to acquire the equipment.
Could repair parts and modification materials remain exempt when attached to customer property in California before the repairer shipped the finished item outside the state?
Yes, if the contract required the repairer to ship the completed property outside California using its own facilities or a carrier.
Could a school-uniform retailer deduct a percentage of student sales paid to the school as a rebate?
No. The payment went to the school rather than the purchasing student, so it was a selling expense, not a cash discount reducing price.
Did buyers' temporary possession become a sale when escrow failed but a separate oral rental agreement paid the seller for immediate possession?
No. Counsel treated the separately paid $100 oral possession agreement as a rental, not a substitute for title. Staff recommended a $164 refund, but the source supplies no Board action or payment.
Did seven months of buyer operation create a sale when escrow could not close because the on-sale liquor-license transfer was denied?
No. Counsel said title could not pass without the license transfer and possession was neither in lieu of title nor secured by retained title. Staff recommended a $90 refund, but no Board action is…
Were all receipts taxable for plastic-laminating consumers' membership cards and identification cards?
Yes. Though the memorandum called it a close question, it treated the laminated item as tangible personal property rather than a service and taxed the entire receipts.
Could an advertising agency act as its client's agent when its own art department prepared reproduction art?
No for that activity. The source treated the agency as seller of its in-house reproduction art because creating art for the client did not involve representing the client in dealings with a third person.
Were ROTC uniforms exempt when a university bought them in its own name and the Army later reimbursed the university through a uniform allowance?
No. The university bought on its own credit, lacked authority to bind the United States, and received only reimbursement. California treated the uniforms as taxable university purchases and held it…
Could a restaurant deduct amounts retained by Diners' Club and similar organizations as cash discounts?
No. The customer received no discount; the retained amount paid for billing and collection services and was a nondeductible business expense.
Did delivery of tanks in Nevada avoid California tax when they returned empty to California for their first paying load?
The letter did not finally decide. It suspected a tax-avoidance device but requested clarification of conflicting delivery and use facts.
Did separate purchase orders make engineering, design, and drawing charges nontaxable when the seller was already obligated to manufacture the equipment?
No. Because the engineering work fulfilled an existing end-product obligation, it was part of taxable gross receipts despite the separate purchase order.
How was the historical section 24402 dividend deduction computed when the payer's earnings included liquidation gain excluded from California's tax measure?
The deductible percentage was the payer's earnings and profits included in California's tax measure divided by total earnings and profits available for dividends. Liquidation gain excluded under…
Were printed multiple-listing cards showing homes for sale, listing changes, and sold properties exempt periodicals?
No. California treated the materials as business reference cards rather than newspapers or periodicals under former Ruling 50.
Does a California dealer make a taxable sale when an installment buyer assigns a conditional-sales contract to a replacement buyer?
It depends. If the dealer repossesses the property or finds the replacement buyer and directs the transfer, the dealer makes a taxable sale. If the original buyer independently finds the assignee…
Was a surplus boat subject to California use tax when its only in-state activity was overhaul before qualifying out-of-state operations?
Not if the facts were as stated. Documentation alone did not create an exemption, but section 6368 could cover qualifying fishing or transportation-for-hire use, and section 6009.1 excluded…
Were a freelance news photographer's retainers and hourly charges taxable when he delivered exposed film to newspapers?
Yes, assuming he was an independent contractor. Delivering exposed film was a taxable sale, and tax applied to the full receipts without service-cost deductions.
Did membership in a California nonprofit stock cooperative make foreign corporate members taxable when they had no California property or business activity?
No. The domestic cooperative's acts, property, and sales were not attributed to members for California doing-business purposes, so foreign corporate members with no California property or activity…
Were sales of live nutria exempt as food animals, and was nutria meat exempt?
Live nutria sales were not exempt because nutria were not ordinarily human-food animals, but nutria meat sold for human consumption was exempt.
Was a Mexican resident's $150,000 profit from selling an airplane purchase contract back to the California manufacturer California-source income?
No. Because the airplane was still under construction and not deliverable, title to tangible property had not passed. The taxpayer sold only the intangible contract right evidenced by the purchase…
Were overriding oil royalties paid to nonresidents from federal oil and gas leases on California property California-source taxable income?
Yes. The ruling treated the payments as advance royalties produced by an economic interest in oil and gas located in California. Because that mineral interest was treated as an interest in…
Which attached business assets were realty when sold with land and buildings, and which small equipment remained tangible personal property?
Attached heavy sawmill machinery, a cooler compressor and motor, and a service-station hoist were realty; a small half-horsepower bench grinder remained personal property.
Could a portable lifeboat radio qualify as an exempt watercraft component when stored aboard ship until an emergency?
Yes. California treated the radio as a component because operation required it to be securely fastened to the lifeboat, grounded, and connected to an antenna. Storage aboard the ship and easy…
What tax consequences arose when a business gave away tax-paid cars to promote another company's products and was reimbursed?
The source found a taxable promotional use by the business and a taxable sale to the reimbursing company. Consideration could come from that company even though the automobile was transferred to the…
Was a drilling-tool repairer the consumer of hard-surfacing material used to retip worn tools?
Yes, where the welded material was not separately identifiable and averaged roughly ten percent of the total charge.
Was brief California retention taxable when a purchased building was dismantled and moved to Arizona within about 60 hours?
Not if the facts showed Arizona personal use or an out-of-state sale with title passing there. The memorandum directed an audit investigation.
Were construction materials bought for real-property improvements on San Nicolas Island exempt because of the island's location or federal use?
No. California treated the island as within the state and applied sales and use tax except where state jurisdiction conflicted with federal governmental purposes.
Could California hold a premises-controlling retailer liable for sales by unpermitted concessionaires that appeared to be the retailer's own?
Yes. Tax Counsel maintained the proposed determination because former Ruling 79 broadly covered unpermitted sellers operating in a retailer-controlled area where the public could reasonably view…
Were automobile service-guarantee charges taxable, and how were repair parts sold to the guarantee company treated?
A guarantee included with the automobile was taxable; a strictly optional guarantee was not. Repair parts sold to the guarantee company were taxable retail sales.
Were replacement parts exempt when installed in repaired cameras before contract-required delivery to customers outside California?
Yes. Counsel treated the parts as exempt because the repair contract required delivery to the customer outside California, even if accession passed title upon installation.
Were contractor-made cabinets sold as fixtures or realty, and how were non-built-in appliances taxed in a lump-sum home contract?
Cabinet treatment depended on land ownership and when title passed. Non-built-in appliances were taxable at fair retail value, including a reasonable markup.
Could a mortuary supplier sell soap to morticians for resale without California sales tax?
No. Because soap was removed after use rather than remaining with the body, the mortician consumed it and the supplier's sale was taxable.
Could a paint seller deduct the unused portion returned by a customer, and who had to refund the related tax reimbursement?
Yes, if the retailer refunded the unused paint's full price and related sales-tax reimbursement. The customer had to seek that refund from the seller, not the Board.
Were fishing tackle and hardware used to repair a qualifying deep-sea fishing boat treated the same under the watercraft exemption?
No. Nets, fishing lines, and fish hooks were taxable tackle. Lag screws, nails, and repair hooks were exempt when used to repair and become component parts of a watercraft used in qualifying…
Were charges to string wires and make connections on an existing utility line taxable fabrication?
No. The line was already erected and in use, so the work was installation; tax applied only to the selling price of materials furnished.
How did California treat a canning service that cooked and sealed a customer's fruit or other commodity in cans?
The canning work was processing treated as a sale. The cans were regarded as sold with their contents and received the cited container exemption.
Did customers' contractual option to resell package display stands to the original vendor create a returned-merchandise exclusion?
No. The customers bought, used, and bore the risk of the stands as intended; exercising an optional resale right was a resale, not a merchandise return.
Could a seller preserve interstate-sale exemption when film prints went first to the buyer or its representative in California before outside shipment?
Only for inspection and return to the seller for shipment. Positive editing was treated as buyer use, and outside shipment by the buyer gave the seller no exemption.
Were Emulphor, orthodichlorobenzene, Triton 770, and Katanol taxable dyeing aids or components of dyed cloth?
The first three appeared taxable as solvents or emulsifiers. Katanol remained unresolved: taxable if a solvent, but incorporated if actually used as a mordant.
Was a road-oil supplier a consumer or retailer in road-surface reconditioning?
It was a consumer when responsible for mixing, spreading, compacting, and final placement of the reconditioned surface; a supplier only furnishing and spreading oil was a retailer.
When was a liquid-asphalt applier a retailer versus a construction consumer?
It was a retailer when oil was mixed or processed before another party placed the final surface, but a consumer when responsible for the final road placement or when oil stayed where spread.
Did displaying locomotives in California for publicity create use tax before they entered service entirely outside the state?
No, provided the locomotives were used here only for exhibition or publicity and performed no California transportation service.
Could a tractor seller rescind a sale, keep a rental charge for the buyer's prior use, and still claim a returned-merchandise deduction?
No. The original sale was complete, and retaining rent or a usage charge meant the seller had not refunded the full sale price required for the deduction.
Did Senvita Minerals qualify as feed rather than a drug, antibiotic, or vitamin?
Yes. California treated it as feed based on its contents, the manufacturer's directions, and the Agriculture Department's product assessment.
Did a later retail sale erase use tax on vehicles that a dealer had already used in California for more than demonstration or display?
No. Section 6401 prevented overlapping tax on a taxed retail purchase; it did not excuse the dealer's earlier taxable use before resale.
Was a vehicle sale exempt when a servicemember took delivery in California, drove it out on a permit, and registered it in another state?
No. The letter said California delivery completed the taxable sale; later removal and out-of-state registration did not exempt the retailer.
Did owner approval of a lower house-trailer price keep the consignment dealer from being the retailer?
Not necessarily. If the dealer could transfer title and did so—by selling the trailer or obtaining and delivering the owner's signed bill of sale—the dealer was the retailer and the sale was taxable.
