Was leased data-processing equipment exempt when substantially installed on foreign-commerce passenger cruise ships?
Yes. The machines were substantially attached, connected to ship power, and used for passenger-service recordkeeping, so California treated them as integral component parts of vessels transporting…
Did storing and programming a custom Illinois-plant computer in California create taxable California use?
No. The computer could function only at the Illinois plant, and its California programming and storage served that out-of-state use under section 6009.1.
Could a corporation claim a defective-merchandise credit when one division replaced equipment it manufactured and transferred to another division?
No. The interdivisional transfer was not a sale, and the purchased raw materials or components were not alleged to be defective, so Regulation 1655 did not apply.
Did temporary California storage and programming make a custom computer taxable when it could function only at an Illinois plant?
No in the hearing officer's recommendation. The computer could function only at the Illinois plant, so California programming was preparation for outside use under section 6009.1 and the officer…
Did a new tractor become taxable when a drive-away carrier used it to tow a separately purchased new trailer out of California?
No. The memorandum treated the new tractor and trailer as one outbound delivery unit, and the tractor seller met the out-of-state-delivery rule.
Did a lease covenant requiring bowling-alley equipment to remain on site prevent taxable sales of the prior lessee's property and trade fixtures?
No. The covenant did not eliminate the lessee's ownership and removal right, so tangible personal property and lessee-owned trade fixtures remained taxable when sold.
Could California tax a unitary business's floating drilling-barge operations on the federal outer Continental Shelf, and where did the related apportionment factors go?
No. FTB concluded that the Outer Continental Shelf Lands Act barred state taxation of drilling-barge operations conducted on the outer Continental Shelf. The apportionment factors tied to those…
Did an eight-page monthly alert analyzing new estate, gift, insurance, will, trust, and probate cases qualify as an exempt periodical?
Yes. California concluded that the regularly issued monthly professional alert qualified for the newspaper and periodical exemption.
Did liquidated damages paid by a seller to the buyer reduce the contract sales price subject to use tax?
No. California treated the stated contract price as the use-tax measure; damages, settlements, or so-called voluntary price adjustments did not reduce it.
Did liquidated damages paid by a seller for breaching a sales contract reduce the California use-tax measure?
No. The stated contract price remained the sales price; damages, settlements, and amounts labeled voluntary price adjustments did not reduce it.
Were monthly computerized law-firm billing fees, initial conversion charges, and separately sold statement paper taxable in California?
Monthly service and initial conversion charges were not taxable, but separately charged customized statement paper was a taxable retail sale.
Were subscription recordings of a religious-music magazine's printed compositions exempt as periodicals because they appeared regularly with related issues?
No. California taxed the recordings even when sold with the magazine because each was complete recorded music; periodic release and continuity were not enough.
Could a manufacturer's long-term lease of pickups to dealers qualify as a sale for resale when dealers made short-term customer rentals?
Yes, if the dealer's resale certificate specifically certified subleasing as qualifying one-way rental trucks or house cars; a blanket certificate alone did not establish the stated treatment.
Was the value of access to a specific mobilehome location included in the taxable price of the home?
No, if part of the price truly bought location-access rights. The contract should state that value separately, or the taxpayer had to prove an allocation.
Could California DMV legally round a vehicle purchaser's use-tax payment to whole dollars?
Yes. Vehicle Code sections 4750.5(d) and 9559 authorized the procedure if DMV followed their treatment of dollar fractions.
Did an advertising tabloid become an exempt periodical component when an independent distributor bagged it with an unrelated exempt publication?
No. Sharing a delivery bag was insufficient without a business tie to the exempt publication's publisher, vendor, or donor, so the use-tax assessment stood.
Were center-mount cranes MTE even when limited speed and cost made self-propelled trips over 10 miles uneconomical?
Yes. The hearing officer found highway transportation was a necessary, essential design use outside a confined area and rejected an arbitrary mileage cutoff.
When was freight-in excluded from or included in a fixture contractor's tax measure?
Freight on a completed fixture installed without further manufacturing could be excluded if sections 6011 or 6012 applied. Freight on components used to manufacture a fixture was included in the…
Was a vessel exempt when it was used only for commercial fishing but its primary catch was abalone taken inside California waters?
No. Section 6368 required commercial deep-sea fishing outside California territorial waters. The fisher's exclusive commercial use and substantial fishing income did not overcome the fact that the…
How did California distinguish highway-designed truck cranes from units confined by design to construction or logging sites?
Design controlled, not a lessee's limited actual use. Highway-capable Truck-Kranes and a wrecking crane were MTE; site-limited units and the described Multikrane were not.
Could a repairer estimate the fair retail selling price of parts by using averages for separate repair categories?
Yes, if each category reasonably approximated parts in the individual repair; one overall average was not allowed, and no parts charge was allowed when none were used.
How were railway sensing cables, attached controls, train-car equipment, and plug-in computers classified?
Sensing cables were materials, firmly attached controls were fixtures, and train-car or mobile plug-in equipment remained tangible personal property.
Could quarterly Bible study guides qualify as exempt periodicals when used in classroom instruction?
Yes. Staff treated noncyclical quarterly guides with new material as periodicals, but kept cyclical, textbook-like reissues taxable.
How did California tax golf-tournament entry fees that included a meal and prizes usable as discounts or gift certificates at the pro shop?
The meal's regular menu price and the full retail price of pro-shop goods were taxable; the remaining fee for the right to compete was not.
Could a construction contractor accept a resale certificate for installed materials or fixtures?
Generally no. Even where a contractor was the retailer of installed materials, the memo said it could not accept a resale certificate for them. A fixture exception applied only in the circumstances…
Which chemicals used to make vinyl sheeting and coated fabrics could be bought for resale?
MEK, nitropropane, acetone, toluene, isopropyl acetate, and stearic acid qualified; mineral spirits remained taxable manufacturing aids.
Were track-mounted mobile shelving systems materials, fixtures, or equipment?
Usually, added flooring and tracks were materials and the moving shelves were fixtures when intended as a permanent specialized-building installation. Facts showing temporary use could rebut that result.
Was an $18 computer-generated astrological world map taxable when each map was customized from the individual customer's birth data?
No, though the source called it doubtful. Each map was custom-produced, and the customer sought personal planetary-location information rather than the paper map.
Could a manufacturer that leased its own MTE trailer pay tax on raw-material cost instead of lease receipts?
Yes. The manufacturer was the consumer of the incorporated raw materials, so it could pay tax on their purchase price; the MTE lease itself was not taxable.
Were charges for processing customer-furnished meat or game taxable, and was the paper used to wrap the finished food exempt?
The processing was a sale but exempt as food. Wrapping paper sold with the meat or game was an exempt nonreturnable container, so its purchase was also exempt.
Should California issue a seller's permit or a use-tax registration certificate to an out-of-state business with no in-state location or inventory?
The 1976 legal memo recommended a use-tax registration certificate, while acknowledging that voluntary seller's permits caused no apparent harm.
Was a contractor's full charge taxable when its work changed a customer's DMV classification from a commercial truck to a house car?
Yes. Work extensive enough to change the vehicle into a house car was a taxable modification, with no deduction for installation labor.
Was jobsite reassembly of free-standing shelving exempt installation labor when the shelving had been assembled, disassembled, and shipped?
No. The shelving was assembled into tangible personal property before placement, and the seller did not separately state labor, show prior title passage, or make reassembly optional.
Could an auto dealer claim a full-price returned-merchandise credit without refunding California registration and license fees?
Yes. Those state fees were excluded from the vehicle's taxable sale price, so retaining them did not prevent a full-price return for sales-tax purposes.
Were liquid nitrogen and carbon dioxide exempt when dermatologists used them to treat skin lesions?
Yes. California treated the cryotherapy agents as medicines when sold to physicians for external treatment of skin malignancies, warts, and similar lesions.
Were cancellation penalties and minimum meal charges treated the same when a retreat group's attendance fell below its reservation?
No. A full cancellation or no-show fee was nontaxable service or damages, but a minimum charge after some meals were served was taxable as payment for those meals.
Would an advertised price including shipping and sales tax 'where applicable' imply tax reimbursement on exempt out-of-state shipments?
No. California said the 'where applicable' qualification was sufficient to avoid treating the price as tax reimbursement on nontaxable out-of-state sales.
Was a bank the retailer of special personalized checks when depositors ordered through the bank and printers mailed the checks directly?
Yes. The appeals recommendation said depositors ordered from, paid, and looked to the bank for performance; printer identification and no markup did not change that.
Could a carpet installer accept a bank's resale certificate when installed wall-to-wall carpeting was leased to a building user?
No. Counsel treated installed wall-to-wall carpeting as construction-contract materials consumed by the installer, even if the lease called it personal property and allowed removal.
Were hormone- or copper-releasing intrauterine contraceptives exempt despite being insert devices?
Yes. California treated all three chemically operating devices as medicine when they were prescribed and furnished through a qualifying statutory channel.
Did a contracted wharf operator qualify as forwarding agent when it accepted, unloaded and consolidated goods for ship or barge reloading?
Yes. Its carrier/consolidation business made it more than a purchaser-designated recipient. But exemption failed when purchaser employees accepted vendor delivery.
Who collected tax when an out-of-state steel seller used a California retailer only as its delivery agent to a California contractor?
The California delivery agent. The 1975 memo treated it as the retailer under section 6007 and required it to collect use tax, not sales tax.
Could California tax a veterinarian's separately billed drug sales above $150 per month while treating lower-volume veterinarians as consumers?
Yes, under the historical practice. The hearing officer found a rational basis for treating veterinarians with separately billed incidental drug sales below $150 per month as consumers while…
Did detailed sold-property data in an MLS publication count as news, unlike a simple list used to delete sold properties?
Yes. Detailed market data counted as news; a simple sold-property list mainly used to delete current listings remained taxable.
Did detailed multiple-listing sold-property data count as news for the historical periodical test, unlike a simple deletion list?
Yes. Detailed market data counted as news and made three exhibits periodicals; simple sold-property deletion lists remained taxable.
Were imported transformers exempt from California use tax when installed on refrigerated containers moving in foreign commerce?
No. The transformers lost import immunity when removed for installation in California, and the containers were functionally used here in a revenue-producing foreign-commerce operation. Section…
Who qualified as an Indian trader, who needed a seller's permit, and did another-tribe membership defeat reservation exemptions?
Only federally licensed persons were Indian traders. Licensed Indian traders needed no permit; licensed non-Indians did, and another-tribe membership did not defeat exemption.
Did a pay-television provider lease its home terminal units when subscribers used them only to unscramble the provider's programming?
No. Provider used units for programming service; subscribers only switched them on/off and paid one periodic programming charge.
Was a charity wine-tasting admission fully taxable when the ticket included wine?
Generally yes, unless the wine was insignificant compared with admission or separately charged. Voluntary donations above a required minimum followed a narrower measure.
How much of a charity wine-tasting admission charge did California treat as taxable?
The entire admission charge, unless the wine was insignificant compared with the admission price or the organization made a separate charge for the wine.
Did banner towing or aerial photography count as common carriage merely because an air-taxi operator performed them under federal authority?
No. Federal authorization did not make those services transportation of persons or property as a common carrier. Public holding out and actual public carriage remained necessary.
Was a per-foot payment to a highway-barrier machine seller taxable as a royalty, and were tax-paid materials used out of state exempt?
The per-foot payment bought skilled operator services and was not part of the machine price, but the materials remained taxable because certification rules were not met.
Was a California helicopter sale exempt when a California organization paid for it but the intended user was Kenya's national park service?
It depended on delivery. Direct transfer of title or possession from the manufacturer to Kenya could qualify; delivery first to the California payer would not. The documents were inconclusive.
Did California tax vehicles bought by service members before transfer orders and delivered through California dealers?
Generally no when the sale or title passage occurred out of state and the purchase preceded California transfer orders; California-inventory courtesy delivery was taxable.
Was a yacht business a true broker or the taxable seller when it controlled the buyer relationship, financed the deal, and caused title to pass?
It was the seller, not a true broker. But the assessment was deleted and refunded because collection against the correct business was already barred by the statute of limitations.
Could a printer exclude separately stated airmail or air-freight charges for sending prospectus proofs to the customer's lawyers and accountants before printing?
No. Shipping proofs was a production expense for the taxable finished prospectus, even though freight for distributing preliminary prospectuses was treated differently.
Were an ad agency's in-house finished art, incorporated typography and copy, and supplier markups taxable despite a client agency agreement?
Yes for the finished art and its incorporated typography, copy, and markups. Properly documented agency purchases could be passed through differently, but marking up a supplier's price was…
Were charges taxable for hand lettering names and dates on certificates, awards, and similar documents furnished by customers?
Yes. The Board treated lettering as artwork under Regulation 1540, comparable to engraving names and dates on new trophies and awards.
Were charges for hand-lettering names and dates on customer-furnished certificates taxable?
Yes. California treated the lettering as artwork and taxed the charge, comparing it to taxable engraving of names and dates on new trophies and awards.
Could allegations of seller fraud or later litigation reduce the agreed vessel price used to calculate California use tax?
No. The completed sale's agreed $60,000 price controlled, and even a later settlement or judgment reducing what the buyer owed would not reduce it.
