Could limited U.S. government contracts count as common carriage when an air-taxi operator also held itself out to carry the public indiscriminately?

Yes. Contracts limited to certain days and no more than one year counted when the operator also offered public carriage and had not bought a particular aircraft solely for the contract.

1975-09-03

Did later out-of-state transport make an 'as is, where is' equipment sale exempt from California sales tax?

No, not when the sale contract imposed no outbound-delivery duty on the seller and shipping details were negotiated only after the sale. A separate Hawaii sale was exempt because its purchase order…

1975-08-29

Did Utah tax paid on a vehicle lease offset California use tax when Utah law exempted property used exclusively outside Utah?

No. Utah did not impose tax on the California lease use, so the memorandum directed the parties to seek a Utah refund instead of a California credit.

1975-08-25

Was a person who placed a septic tank in its final hole a construction contractor?

Yes. Placing the tank in its final resting place was the controlling last act, so the person made a real-property improvement and furnished and installed a material even if others dug the hole or…

1975-08-19

Did live crab and lobster become taxable hot prepared food when the seafood market killed them for customers in boiling water?

No. The heat resulted from killing seafood sold live to prove freshness, not an intent to sell ready-to-eat hot food, so the recommendation deleted the tax.

1975-08-04

Was a service station's sale of removable car-wash equipment exempt as an occasional sale because car washing was a service activity?

No. Gasoline purchases determined the car-wash price, making the wash and taxable gasoline operations integral parts of one business. The removable equipment was tangible personal property held in a…

1975-07-28

Could an agent's single business-asset sale be occasional when the agent's only property sales were attributed to a Board-designated section 6015 retailer?

Yes, under this categorical 1975 memorandum. It treated covered sales as the designated retailer's sales, so those sales did not require the agent to hold a permit and one asset sale was occasional.…

1975-07-28

Could a telephone company treat an old touch-tone phone exchanged free for a rotary model as returned merchandise after extended customer use?

Yes. Full original-price credit and a no-charge equivalent replacement made the exchange a merchandise return rather than a taxable trade-in.

1975-07-21

Did California use tax apply when an enrolled-Indian partnership bought pipe from Nevada for installation on a reservation and took title there?

No. Although the contractor was the consumer of the pipe, California said use tax did not apply because the enrolled-Indian partnership purchased it on the reservation.

1975-07-15

Was a mobile medical-billing company's lump-sum charge taxable when it photocopied ledger cards and supplied, folded, sealed, metered, and mailed envelopes?

Yes, except separately established postage. The contract included taxable photocopies and envelopes, and mailing services were not separately stated.

1975-07-14

Did Regulation 1630 apply to a contractor that packed military household goods but did not itself perform the shipment?

Yes. The hearing officer applied Regulation 1630 to packing and loading even without shipment and treated the contractor as consumer of untaxed materials because its Armed Forces contracts bought…

1975-07-11

Were truck-mounted aerial lifts, cranes, and digger-derricks drawn from an interstate rental fleet mobile transportation equipment?

Yes. They traveled state to state under their own power and carried both the driver and permanently attached rig, so rental receipts were not the taxable measure.

1975-06-26

When can a manufacturer accept a resale certificate for special tooling or printing aids that its customer plans to pass to another customer?

A specific certificate generally supported resale, but a blanket certificate covering products and tooling required proof that the aid was resold before any manufacturing use.

1975-06-24

Were hourly charges taxable when a staffing company supplied designers, draftsmen, and engineers who worked at the client's site under client supervision?

No. The workers were special employees because the client supplied the workplace and property and directed their work; personal tools did not change that.

1975-06-06

Were hourly charges for designers, draftsmen, and engineers taxable fabrication when the client directed their work?

No. The workers were treated as the client's special employees because the client supplied the workplace, property, supervision, and control.

1975-06-06

Can a buyer be a California successor without acquiring the seller's inventory or accounts receivable?

Yes. Leases, furniture and fixtures, trade name, customer lists, and goodwill supplied the essential elements of the art-gallery business. Successor status arose from buying those assets, even if…

1975-06-05

Were petroleum-emulsion nonadhering dressings and packing strips exempt medicated dressings?

No. California found that the emulsion only gave the dressing nonadhering and wicking characteristics rather than acting as medicine on the body.

1975-05-30

Did a building kit with factory-made walls and roof, but no factory-made floor, qualify as factory-built housing?

No. The regulation required factory-built wall, floor, and roof elements; an onsite concrete slab or mud sill did not supply the missing factory-built floor.

1975-05-30

Did a California DMV registration classification conclusively determine a vehicle's sales-and-use-tax treatment?

No. Auditors were to apply the vehicle's actual MTE classification despite DMV labels; a taxpayer disputing DMV-based treatment had to provide corrected registration or the vehicle for examination.

1975-05-28

Did consenting to a debtor's occasional-sale transfer destroy the secured seller's later repossession-loss deduction?

No. The seller remained the taxed retailer and security holder, and the later repossession from the transferee produced an allowable verified loss.

1975-05-15

Did itemized packing charges and an interstate tariff prove a household-goods carrier sold containers to customers before using them?

No. The signed charge documents and tariff phrases did not expressly pass title before packing use. Under Commercial Code section 2401, title passed at destination after packing, hauling and…

1975-05-12

Was an aircraft engine always MTE when leased, even if a movie studio used it only as a wind machine?

No. Component-part treatment depended on transportation use: the wind-machine lease was not MTE, while a later lease for installation on an aircraft triggered MTE cost-basis tax with a rental-tax credit.

1975-05-06

Was Goetz Pale Near Beer exempt because it was not federally taxed or registered in California as an alcoholic beverage?

No. California treated it as taxable malt liquor and, absent contrary facts, as a naturally carbonated beverage despite its low alcohol.

1975-04-29

Were automated drawings taxable when the provider also performed engineering computations, design, layout, and independent professional judgment?

Engineering and design services were not taxable, but automated drafting that merely produced drawings from predetermined specifications remained taxable.

1975-04-16

Were live forage fish exempt when commercial deep-sea fishermen bought them for bait and chumming?

Yes, for the eleven listed kinds when sold alive. They qualified as food-animal life under section 6358(a), even though purchased as bait rather than human food.

1975-04-16

Was a truck rental estimated at five to six months a lease for more than 31 days if the renter could end it on 24 hours' notice?

No. The memorandum treated 24 hours as the only definite term, so the lease was for less than 31 days, assuming section 6024's other conditions were met.

1975-04-10

Was an out-of-state seller's sale of telephone-line components a taxable retail sale?

Yes. The components were tangible personal property and materials when sold to the construction contractor; only the completed telephone line lost that status under section 6016.5.

1975-04-04

Was an insurance-company affiliate included in a California unitary combined report when it was operationally integral to the affiliated business?

No. Even when an insurer was an integral part of the unitary business, FTB excluded its income and apportionment factors because the constitutional gross-premiums tax made it exempt from the…

1975-03-28

Was an unattached aircraft engine leased and held on standby already mobile transportation equipment before installation?

Yes. From November 23, 1970, the opinion treated standby engines as MTE before attachment, shifting tax from rental receipts to lessor cost with an offset for rental tax already paid.

1975-03-25

After the November 23, 1970 change, did Regulation 1661 apply to a standby aircraft engine before installation?

Yes, from its initial lease under the post-November 23, 1970 rule. Before that change, the opinion treated California rentals of unattached engines as continuing sales.

1975-03-25

Did a partner's withdrawal and firm-name change trigger tax when vehicles were reregistered to a continuing partnership?

No on the facts represented by telephone. The agreement reportedly continued the same partnership after withdrawal, so vehicle ownership did not change and reregistration under the new firm name…

1975-03-21

When did a timely federal revenue agent's report or other federal overassessment report count as a California claim for refund?

A taxpayer-filed federal report could be a California refund claim when accompanied by a clear refund request and grounds specific enough for FTB to investigate. A clear but incomplete request was…

1975-03-20

Did registering a dealer demonstrator with DMV automatically create sales or use tax or prevent demonstration-and-display treatment?

No. Registration alone did neither, but the dealer had to prove the vehicle's actual qualifying use, with an especially heavy burden for a solely demonstration-and-display claim.

1975-03-18

When did California treat in-place fixture transfers among landowners, lessees, successor lessees, and fixture lessors as taxable personal-property sales?

Tax generally depended on contemplated or present removal rights. Transfers between the landowner and its lessee were not taxable unless removal was contemplated.

1975-03-18

Did a standing purchase order satisfy the separate-statement rule when the seller's invoice showed the freight amount but did not label it as transportation?

Yes. The standing order, instructions, and invoice read together stated the amount, passed title at shipment, and required freight to be removed before tax was computed.

1975-03-17

What could a transferee challenge in a California protest or reassessment petition when the original taxpayer was active or suspended?

A transferee could protest or petition over the elements of transferee liability even when the transferor was suspended. But it could challenge the transferor's underlying tax liability only if the…

1975-03-13

Could a qualified California farmers' cooperative deduct income from activities outside its marketing, purchasing, and producing functions when it properly allocated that income to members?

Yes. FTB interpreted former section 24404 to allow a qualified farmers' cooperative to deduct all income properly allocated to members, regardless of source. The source of the income—member…

1975-03-13

Which old California franchise-tax prepayment qualified as the commencing-year credit against final-year tax for corporations operating around the 1929 act and 1933 amendment?

The qualifying credit depended on when the corporation began business and whether its first prepayment covered a full year. Some pre-1929 calendar and fiscal corporations received a credit based on…

1975-03-11

Was a Trans-O-Vac pickup with a vacuum sweeper installed on its chassis mobile transportation equipment?

Yes, although the opinion called the issue doubtful. The pickup-mounted sweeper was capable of transporting persons or property substantial distances.

1975-03-11

Did equipment keep tax-paid status when one partner withdrew, four joined a new partnership, and that partnership leased the equipment?

No under stated history. Original partnership ended; incoming owners' contributions for new partnership interests did not preserve equipment tax-paid status.

1975-03-11

Did title passing on delivery in California turn a direct out-of-state vendor shipment into a California sales-tax sale?

No. The roofing contractor ordered directly from out-of-state vendors with no participating California office or agent, so Regulation 1620 excluded sales tax despite title passing at delivery. The…

1975-03-10

Was a partnership-to-corporation asset transfer occasional when partners received different stock classes and one also received corporate notes?

Yes on the stated assumptions. Staff said over 80 percent of ultimate ownership remained because immediate-liquidation rights in the transferred property were substantially similar, despite…

1975-02-26

Were plug-in intercom handsets fixtures like hard-wired units?

No. Plug-in handsets remained tangible personal property and were taxed at fair retail selling price; comparable units hard-wired into the system were fixtures.

1975-02-26

Could a lessor avoid tax on current rental receipts without old purchase records because Regulation 1698 allowed records to be destroyed after four years?

No. The four-year rule did not authorize destroying records still needed to prove a current tax-paid-rental exclusion, and the taxpayer failed to prove tax had been paid on the shore clamps.

1975-02-25

Could a lessor rely on the four-year record rule after destroying invoices needed to prove current rentals came from tax-paid equipment?

No. Records supporting a current tax-paid-rental exclusion had to be kept while useful, and the taxpayer failed its burden without them.

1975-02-25

Was installing permanently affixed car-wash equipment a construction contract?

Yes. The installer was a construction contractor, the car-wash equipment was a fixture, and under the lump-sum contract tax was measured by the cost of the purchased completed equipment.

1975-02-25

Did destroying production samples during customer-requested testing make the manufacturer the retailer or consumer of those samples?

No. Production testing to destruction created no separate use-tax liability, even when customer-requested and separately billed.

1975-02-18

Were separately billed charges to repair forklift damage from a lessee's abuse or improper use taxable rental receipts?

No. They compensated extraordinary damage rather than use, and repair parts joined equipment already taxed on rental receipts.

1975-02-11

Which costs could a retailer retain as rehandling and restocking charges when customers returned special-order goods?

Direct return-process costs could be retained transaction by transaction, including authorizations, handling, return freight, supplier charges, and credit processing; overhead and reconditioning could not.

1975-02-03

Was California DMV's charge taxable when it furnished driver-license public-record data on magnetic tapes, punched cards, or printouts?

No. Because public-records law required DMV to furnish identifiable records for a reasonable fee, providing the data was a government service, not a sale.

1975-01-29

Could a hospital buy disposable patient menus tax-free as nonreusable components of the meals it served?

No. The menus communicated next-day meal choices and did not become components of the meals, so the hospital consumed them.

1975-01-29

Did a school become a joint adventurer and retailer when it supplied gasoline to a service-station operator and received cost reimbursement plus a variable return?

The hearing officer found a joint venture based on community interest and shared profits and losses, classified the school as a gasoline retailer, and recommended no adjustment to the dual…

1975-01-20

Did use tax apply to materials bought for resale but experimentally used in an unsuccessful printing-system development program before any sale occurred?

Yes. Experimental use to test feasibility was a taxable California use even though the materials were intended for a system that might later be sold.

1975-01-17

Did a California purchaser have to report use tax directly when a registered in-state retailer failed to bill or collect it?

Yes, under the memorandum's tentative reading. A purchaser remained liable until tax was paid to California or a sufficient receipt came from a collecting retailer; sections 6452 and 6453 required a…

1975-01-15

Was a wood processor's equipment sale occasional when it incorporated ex-tax fillers, adhesives, stains, inks, and sealers into customer-owned wood?

No. Although processing property for a nonconsumer customer was not itself a sale, the processor sold the incorporated components for consideration and therefore conducted an activity requiring a…

1975-01-14

Was a separate camera-ready-copy charge taxable when the printer retained it and sold the manuals for resale?

No. The charge followed the manuals' resale treatment because the printer retained the copy and used it to print them; separate invoicing did not create another sale.

1975-01-07

In a chain of taxable equipment leases, who had to collect the tax when every earlier sublease was an established sale for resale?

The final sublessor leasing to the consumer had the collection duty; if collection failed there, the consumer-lessee was next, not an earlier lessor.

1974-12-05

Were custom fishing nets attached by cable and winch exempt when used in commercial deep-sea fishing operations?

Yes. California reconsidered an earlier contrary letter and found that the redacted net type's construction, attachment, and use did not materially differ from exempt purse-seine nets or dragnets.…

1974-12-02

Were separately stated standby charges after ready-mix concrete reached the customer's destination included in California taxable receipts?

Generally no once tender occurred and title passed after a reasonable unloading opportunity; the precise result depended on the delivery facts.

1974-11-26

Could a restaurant company avoid tax by transferring businesses to a new corporation for initial stock, then transferring that stock to a related company for consideration?

No exemption was recommended. The same-day asset-for-new-stock and stock-for-consideration steps were interdependent, so staff treated them as one substantive transfer of restaurant businesses for…
