Which specifically described pacing, cardiac, ventricular, and diagnostic catheters did a 1978 California letter treat as exempt or taxable?
Pacing catheters and electrodes intended to remain at least six months were exempt, and the letter repeated that ventricular and cardiac catheters were exempt. Pressure-monitoring, diagnostic, and…
Who owed tax when lighting fixtures sold for resale were damaged in transit and the manufacturer billed the carrier?
Under Method 1, the carrier's damaged-goods purchase was taxable at fair retail value unless bought for resale. Under Method 2, its purchase of the replacement was taxable at the full charge.
When did a construction contractor have to report tax on materials and installed fixtures?
Materials were reportable when removed from resale inventory and allocated to a contract; fixtures were reportable no later than installation. The completed-contract income-tax method was not allowed.
Which conveyor components and labor were fixtures, materials, taxable fabrication, or installation?
Supports, frames, catwalks, and railings were materials; rollers, bearings, motors, and moving mechanisms were fixtures. Shop and pre-attachment labor were fabrication, while permanent attachment…
Was an early equipment buyout taxed only on the lease's end-of-term option price, or on the full amount paid for immediate title?
The full amount. The early buyout was a new title-transfer contract, including retained security deposit but excluding stated tax reimbursement.
Did California tax an out-of-state locomotive purchase when the locomotive entered California in interstate service and stayed in that service?
No. The sale occurred outside California, and the locomotive was placed in interstate service before entering the state and then used continuously in interstate commerce.
Could a concrete-pipe manufacturer buy Hydropel waterproofing compound for resale?
Yes, when used to manufacture pipe sold to customers. The testing-lab information showed Hydropel was bought for incorporation into the concrete product.
How did the Board distinguish a potentially taxable corporate asset sale from a statutory merger?
An asset sale involved a transferor conveying assets and receiving consideration; a later dissolution was optional and separate. A statutory merger followed the governing corporate law: filing the…
Did specialized booster groups or student-only fundraisers qualify as PTA-equivalent organizations under section 6370?
No. Specialized groups generally served only students tied to their activity, and student-only fundraising groups lacked the parent participation required for PTA equivalency.
Was a charge for filling a customer-furnished aqua lung taxable when the business merely provided its compressor, and what about prefilled cylinders?
The compressor-only service was not taxable when the customer supplied the aqua lung. Sales of air already compressed into cylinders or tanks delivered to purchasers remained taxable.
Which walking heels, head halters, elastic bandages, and related devices did California treat as medicine?
Walking heels needed for casts and fully worn head halters qualified; bar-supported halters did not, and elastic or medicated dressings depended on function.
When were surgical evacuators, tubes, embolectomy catheters, and temporary pacemaker leads exempt?
Postoperative waste-removal evacuators and tubes qualified; intraoperative or medication-delivery use did not, and the described surgical embolectomy catheters were taxable.
Were tracheostomy and endotracheal tubes exempt when used to breathe for a patient and remove waste?
Yes, but only for postoperative use. California denied the cited exemptions when the tubes merely aided a patient temporarily during surgery.
Were Hunter tendon implants used in reconstructive hand surgery exempt medicines?
Yes. California treated the permanently implanted tendon devices as exempt because they assisted the functioning of a natural limb.
Were coil-type and hollow-fiber hemodialysis dialyzers exempt related supplies?
Yes. California exempted both dialyzer types because they filtered a patient's blood during treatment on an artificial kidney dialysis machine.
Was a feed-mixing wagon MTE even though it usually moved only short distances on one farm and its lease use occurred in Texas?
Yes. The truck-mounted wagon could transport feed substantial distances and actually traveled California-to-Texas; the lessor therefore owed tax despite the lessee's out-of-state use.
Did buying a seller's real property and equipment alone make a buyer a successor when it began a different business?
No. The buyer did not acquire the trade name, customer list, receivables, covenant not to compete, or inventory. It bought operating assets but not the going business or a stock of goods.
Who owed sales tax when a court-appointed trustee sold a taxpayer's assets under an antitrust divestiture order?
The taxpayer owed tax on taxable fixtures and equipment. The trustee acted as the taxpayer's sales agent, not the retailer, because court approval and the taxpayer's objection right limited the…
Did exchange value include only the other party's purchase price, or also freight, tolls, inspection, import, broker, and tax costs?
It included all direct costs incurred before title transferred, not just purchase price. Cost served as the market-value proxy when the parties had no agreed dollar price.
Were Trader Joe's lecithin granules taxable even though the one-pound bag made no use or supplement claims?
Yes. The Board treated the granules as a specially compounded high-nutrition dietary supplement despite the label's limited information.
Could a grocer earn credit interest and reduce prior-period interest by intentionally overpaying later quarterly returns?
No. Later returns had to report their own quarter, not serve as self-help corrections for earlier deficiencies, and the intentional overpayments earned no credit interest.
Was a donut shop a taxable drive-in merely because it had takeout windows, 15 parking spaces, and outdoor trash receptacles?
No. Evidence showed the parking primarily served inside diners and employees, not customers eating in cars, so the recommendation granted the petition.
Were tax-paid airline parts later resold from regularly traded inventory disqualified as property committed to standby use?
No. California treated the parts actually resold as not committed to standby use and declined to broaden the standby theory for airline inventories.
Was intravenous tubing exempt because federal law restricted it to physician-ordered hospital use?
No. California taxed the tubing as a device, although the intravenous solution passing through it could qualify as medicine.
How did California tax deposition transcripts, simultaneous carbon copies, first copies for other litigation parties, and additional photocopies?
Reporting and the original plus simultaneous carbons were services. Each other party's first required copy was nontaxable, while additional copies were taxable.
Was giving a Bible in response to a requested or suggested donation a sale for California sales-tax purposes?
Yes when a specific or minimum amount was tied to receiving the Bible. A general donation request with no suggested minimum or condition was not a sale.
Could an interior decorator exclude design and service fees from taxable receipts when also selling furnishings or custom furniture?
Only independent professional services could be excluded. Design and acquisition work tied to furnishings, especially custom furniture, remained part of the taxable sale.
Where did a vessel's first functional use occur when the lessor sailed it into California?
It depended on the trip's purpose: sailing in to find any lessee was California use, while sailing in to deliver to a specific lessee was out-of-state use.
Did performing bank-like functions and receiving financial-corporation franchise treatment make American Express a bank for use tax?
No. Counsel concluded bank status required a state or federal bank charter, and classification as a financial corporation under a different tax law did not create a use-tax exemption.
Could ordinary medicines be exempt when sold without a patient prescription to a health facility?
Yes, if the buyer was a qualifying health facility and the medicines were later furnished to patients under physician orders; equipment sterilizer remained taxable.
Was a beneficiary's sale of her entire interest in an estate merely an intangible transfer when the estate included personal property?
No. Under the probate statute cited in 1978, title vested in the beneficiary at death subject to executor possession. Her interest transfer was treated as a sale of the inherited items, so the…
How did California tax one annual charge covering a quarterly professional newsletter and a yearly manual revision?
The quarterly update was an exempt periodical, but the annual revision was taxable. The bundled price had to be allocated, using revision replacement cost as a proper basis.
Were trailer-mounted water-purification and water-chilling units mobile transportation equipment?
Yes. California relied on trailer licensing and the units' design and capability for long-distance highway travel, even though transportation was ancillary to their onsite function.
How did California distinguish transportation charges for contractor-consumed materials from charges involving fixtures sold by the contractor?
Supplier delivery of consumed materials followed Regulation 1628, while the contractor's later jobsite transport was outside the tax measure; stated-price fixture sales were different.
Could a successor claim a bad-debt deduction when the predecessor made the sale and paid the tax?
Yes, if the successor was statutorily liable for that tax and suffered the bad debt, subject to the successor-liability purchase-price limit.
Was cold prepared food taxable as hot food when customers could heat it themselves in a microwave before or after paying?
Generally no when the ovens were readily customer-accessible; vendor-only ovens indicated taxable hot sales for normally hot foods. Separately sold bakery goods remained exempt.
Was the contractor-manufactured framework holding a state freeway sign a fixture or construction material?
A fixture. Attached as one unit to bridge anchor bolts, it supported the sign without becoming an inseparable structural part and retained its identity as an accessory.
What tax responsibility did a vehicle broker assume by completing a report of sale, and did that extend to accessories?
Completing the report made the vehicle sale occur through the dealer, so the dealer reported tax on the vehicle even as a broker. Accessories were different: the dealer was their retailer only if it…
Did a buyer's later false statement that it resold property or paid use tax relieve a seller lacking a timely certificate?
No. Later evidence could rebut taxability only if true; false statements did not relieve the seller, while use-tax liability remained with the purchaser.
Who owed tax when dealers earned catalog premiums by purchasing resale merchandise and an out-of-state supplier shipped the premiums directly?
The program sponsor was retailer of the premiums. Tax applied to premiums delivered to California dealers, measured by the sponsor's cost absent evidence of greater consideration; out-of-state…
Was a motel's business-asset sale occasional when another authorized retailer reported tax on the motel's only prior vending-machine sales?
Yes. The motel operator was not required to hold a seller's permit because the Board-authorized retailer reported the vending sales under section 6015, so the business sale qualified as occasional.
Were blood tubing, cannula systems, declotting kits, and related hemodialysis supplies exempt prosthetic devices?
Generally no. California taxed the listed supplies, but allowed a cannula-system exception when the system was permanently implanted in the human body.
Was Pro-Life Protein Formula 96 exempt when the soy protein powder was mixed into drinks and ordinary foods?
No. California taxed the specially balanced soy-protein formula as a protein dietary supplement designed to increase nutrition.
When did supplied programmers count as special employees rather than sellers of taxable programs?
The customer's legal right to control the work was primary. Contracts for finished machine-readable programs were taxable; genuinely customer-directed hourly help could be nontaxable.
Which compression garments, supports, prostheses, pumps, and wheelchair accessories did California treat as medicine?
Physician-directed orthotic garments and integral garter belts qualified, as did breast prostheses; pumps and many devices were taxable, and wheelchair items had to be part of the chair.
Was a specialist's separate charge for drilling finger holes in a customer's new bowling ball taxable fabrication labor?
Yes. Drilling an undrilled new ball to fit the customer's hand was a step in manufacturing the finished article and was taxable fabrication labor.
What value entered California's property factor when replacement property was acquired through an involuntary conversion or property exchange?
Generally, the replacement property carried over the converted or exchanged property's original cost for the California property factor, adding back prior depreciation and ignoring unrecognized…
Were leased parking gates and door locks fixtures treated as tangible personal property when the equipment lessor retained removal rights?
Yes if equipment lessor retained removal right and did not lease realty. Rent was taxable unless property was acquired tax-paid in same form.
Were separately leased parking gates and door locks taxable as tangible personal property?
Yes. When the lessor retained removal rights and did not lease the realty, California treated the gates and locks as tangible personal property and taxed lease receipts unless the tax-paid leasing…
How did California tax van conversions for dealer contracts, incomplete vans, complete new vans, and used vans?
Dealer-requested house-car conversions and work on incomplete vans were fully taxable. Complete new or used vans were taxed on fabricated parts, while installation and refitting could be exempt.
When could California disregard corporate separateness and pursue a parent corporation for its subsidiary's tax?
The memo described a single-identity theory as one way to set aside corporate separateness. It listed common ownership, officers, facilities, operations, financing, assets, and advisers as factors.
Could a cracking-catalyst maker buy ammonia and sulfuric acid for resale when only about 2% remained, and did caustic soda receive the same treatment?
Ammonia and sulfuric acid qualified because the necessary remainder entered the catalyst; caustic soda was taxable unless the maker proved it was intended to remain.
Did losing about 98% of ammonia and sulfuric acid during catalyst production prevent the chemicals from being bought for resale?
No. The necessary remainder entered the sold catalyst, and the large loss was a consequence of incorporation; caustic soda remained taxable absent contrary proof.
Were cesium-137 and strontium-90 radiotherapy sources exempt medicines when hospitals used them for cancer treatment?
No. California taxed the sources as devices or physical equipment, even when used intracavitarily for treatment rather than as external equipment.
When did section 6247's California-use presumption apply to property delivered outside the state to a California resident?
The memorandum required sufficient California involvement, such as property here when contracted for, negotiations here, or an order originating here.
Did out-of-state vehicle purchases escape California use tax merely because they crossed state lines before operating here?
No. Vehicles first functionally used in California or principally used here were taxable; units first dispatched in interstate service and kept there were removed from tax.
Did testing a mold at the buyer's extruder or passing title there automatically defeat export and interstate exemptions?
No. Temporary testing and title passage were not automatically fatal if the mold returned to the seller for contractually required out-of-state delivery. Direct seller delivery to an export packer…
For valuing restaurant employee meals, should flat shift pay be divided by eight hours or reduced for the employee's half-hour lunch period?
The memorandum used the full eight-hour shift. Employees were paid a flat amount for eight hours, so that basis controlled the hourly wage and meal value.
How did California classify and tax different kinds of walk-in coolers?
Complete freestanding coolers were tangible personal property; assembled rooms became fixtures only when connected to refrigeration; built-in panels and piping were materials, while compressor and…
When did a prefabricated walk-in refrigeration room become a fixture?
Not merely when its panels were assembled. California said the freestanding room remained tangible personal property until connected to the coolant system; the person making that connection…
