Were client-specific demographic and profile reports taxable when delivered on paper or floppy disk?
No, except additional copies. Reports built from client data or matched with the provider's database were services, and the delivery media were incidental.
Were prospectuses and equipment catalogs exempt when sent free through intermediaries, retained in inventory, or delivered to the purchaser's employees?
Prospectuses sent free to underwriters, brokers, or investors and 80% of catalogs sent free to end users qualified. Inventory and employee-delivered portions did not, absent a separate…
Did letters and envelopes printed principally to solicit donations qualify for California's printed-sales-message exemption?
No. The Board withdrew its earlier favorable advice because the materials principally solicited donations rather than advertised or promoted goods or services.
Was a record company's retail resale of a master tape taxable, and what amount was included in the tax measure?
Yes. Sales tax applied to the resale, but Regulation 1527 limited the measure to the sale price of the unprocessed recording medium—the blank tape.
Were FOB-mill lumber sales exempt merely because the buyer's carrier removed the goods from California?
No without a contract requiring out-of-state shipment. But a true resale buyer could issue a certificate even without a California permit if it noted why none was required.
Was additional tax due when an editor returned a producer's cut and spliced qualified-motion-picture film after paying tax on editing equipment and supplies?
No. The editing service was nontaxable, and after tax was paid on splicing tape, grease pencils, viewer bulbs, equipment, and maintenance items, no further tax applied.
Who was responsible for California use tax when an indenture trustee collected rent but the owner-lessor retained the equipment?
The owner-lessor remained responsible. An indenture trustee with only lender security could collect assigned rent without becoming retailer.
Was lumber exempt when an Arizona buyer's carrier picked it up f.o.b. at a California mill, and could the buyer give a resale certificate without a California permit?
The described sale was not an exempt interstate shipment because the contract required delivery only at the California mill. But the seller could accept a good-faith resale certificate from an…
Were surgical training films qualified motion pictures, and how were intermediate processing, student exhibition prints, reels, cans, and aerospace films treated?
Training films qualified: intermediate processing was nontaxable, but student exhibition prints and their film, reels, and cans were taxable; aerospace facts were insufficient.
Did an autotransfusion system qualify as exempt medicine because it handled the patient's blood?
No. California taxed the system because it reinfused the patient's blood rather than draining natural waste from the body.
Were charges for custom processing, dodging, printing, enhancing, and mosaicking radar film into film positives taxable?
Yes, on the unclear stated record. Month-long, higher-precision custom radar processing costing several thousand dollars still appeared to be taxable fabrication rather than professional…
Were custom Landsat mosaics taxable tangible personal property when technicians registered, overlapped, spliced, and enhanced satellite scenes?
Yes, on the unclear stated record. The memorandum analogized Landsat mosaics to taxable noncontrolled visual mosaics, not precisely engineered photomaps, so customization and customer-supplied maps…
Did sales or use tax apply when an owner contributed a debt-free aircraft to a corporation without stock, assumed debt, or other consideration?
No. With no actual consideration, the capital contribution was not a sale or purchase, even if an FAA bill of sale recited formal consideration.
Did a photocopied resale certificate from a billing affiliate protect a seller when another entity was the actual purchaser?
No. The certificate named the wrong purchaser, and the historical rule also required an original purchaser, agent, or employee signature rather than a photocopy.
Would contributing an aircraft to a corporation without stock, debt assumption, or other consideration be taxable?
No, if no consideration was actually paid or received. An FAA form recital would not change that, and the corporation's proposed MTE lease also would not be taxable.
Were specially printed automotive letters, brochures, posters, envelopes, and mailing tubes exempt when the printer mailed them free to dealers?
Yes. The letters, brochure, and posters principally promoted automotive products and met the order and delivery conditions; envelopes and tubes sold with them were exempt shipment containers.
Were hypothermia blankets sold to hospitals exempt when used with dialysis machines?
No. California treated the blankets as taxable durable medical equipment, and incidental dialysis use did not change the result.
Were charges for turning client timesheets into bills and management reports taxable, and how were related software, training, and installation treated?
Timekeeping, billing, and management reports from client data were nontaxable services; software and separately charged training materials were taxable.
How did California distinguish dealer incentives from manufacturer consumer rebates when computing tax on a vehicle sale?
Dealer incentives could reduce retail price when passed through, but manufacturer consumer rebates remained fully taxable even when assigned to the dealer.
Did manufacturer rebates and dealer incentives reduce the taxable selling price of a vehicle in the same way?
No. Dealer incentives reduced the dealer's cost and could reduce the taxable retail price, but consumer rebates remained fully taxable even when applied to the price.
Should DMV collect use tax on a transfer-only title transaction for a vehicle not currently required to be registered?
No. Section 6292 did not authorize DMV collection when the transferred vehicle was not required to be registered under the Vehicle Code.
Was a pre-revenue research company's one-time sale of computer-product work in progress taxable when the unfinished software was delivered on tangible media?
No under the proposed facts. Because the company remained in R&D, had no revenue, and needed no seller's permit, counsel said a single sale of software work in progress would be occasional. No…
Were negative-cutting charges and incidental transferred materials taxable after section 6010.6 took effect for qualified motion pictures?
No. Negative cutting was a qualified production service; the cutter consumed and paid tax on materials, while no separate tax applied to materials transferred incidentally.
Were remanufactured or reconditioned pallets exempt used returnable containers when sold to a bottler for refilling?
Possibly, but the facts were incomplete. Light repairs could preserve used status; work that effectively created a new pallet would make the sale taxable.
Did extensive rebuilding of used oil drums leave them classified as used returnable containers?
No. California's cited drum precedent treated replacement of tops, bottoms, and plugs plus cleaning and repainting as creating new taxable returnable containers.
Were transit-mix, hookup, and pumping charges for cementing oil wells taxable?
No. They were installation steps under the described construction contracts. A lump-sum contractor could buy cement tax-paid, but blending it for a canceled job prevented a resale deduction.
Did qualifying medicine sales to professional medical, dental, or podiatry entities receive practitioner treatment?
Yes. California gave qualifying professional corporations and partnerships the same medicine-sale treatment as licensed individual practitioners.
Did personal property tax enter taxable rentals when a financial-corporation lessor paid it and the lease required reimbursement from the lessee?
No. Tax Counsel applied the bank rule: the lessee was treated as owner and personally liable, so the property-tax amount was not taxable rentals payable.
Were Medifast 70 and Pro-Call 100 exempt when a physician furnished them to treat obesity?
Yes as medicines furnished by the physician to patients for obesity treatment, but not as food products under the historical labeling and calorie rules.
How was furniture taxed when title passed to a bank outside California and the retailer assembled the parts in California?
The corrected annotation treated the knocked-down furniture as subject to use tax and the in-state assembly as taxable fabrication of customer-furnished parts.
Were sales to American Institute in Taiwan members exempt when they held U.S. State Department tax cards?
Yes. The Taiwan Relations Act and federal identification supported exemption to the extent specified on the State Department Tax Exemption Card.
Was the 12% federal retailer's excise tax on heavy trucks included in the California sales- or use-tax measure?
No. Because the federal heavy-truck excise tax was imposed on retail sales, California excluded it from gross receipts and sales price.
When an advertising agency and printer billed separately, which sale could qualify as printed sales messages, and were photography and art used for color separation taxable?
Only the printer's sale of finished printed matter could qualify under the separate contracts. Photography and art used in California as printing aids remained taxable even if later production…
Could separate advertising-agency and printer charges qualify for California's printed-sales-message exemption?
Only the printer's sale of qualifying printed matter could be exempt. The agency's mechanical was not a printed sales message, and printing aids used in California were taxable.
Was a motor-vehicle lessee's upfront capitalized-cost-reduction payment subject to California tax?
Yes. No exclusion covered the lease payment; if it reduced later rent, California treated it as advance rent taxable when the lessor received it.
Was powdered, milk-free Isomil exempt when it could supplement breastfeeding or provide an infant's only nutrients?
Yes. California treated Isomil as exempt baby food even though it was powdered and could be an infant's sole nutrient source.
How would California tax replacement generators made in Canada for a federal hydroelectric project if title passed before or after they entered California?
If federal title passed in Canada, the memorandum found no California sales tax and did not believe use tax applied; otherwise the contract chain determined the measure.
Is a charge for bending steel mesh taxable when an affiliate supplies the mesh?
Bending steel mesh was fabrication. The charge was nontaxable when the affiliate resold the mesh, but taxable when it consumed and installed the mesh as a contractor.
Could a weekly floppy-disk subscription containing only medical-journal tables of contents qualify as a periodical without articles or its own reader software?
Yes. Format and articles did not matter; tables of contents and tabular data qualified, while separate reader software was taxable.
Did using rejected silicon wafers to test manufacturing processes make their original resale cost taxable?
No. The rejected wafers were manufacturing scrap, so their original cost remained nontaxable; outside vendors' charges to back-lap them were taxable.
Did rejected silicon wafers become taxable self-consumed inventory when back-lapped into process-testing aids, and was vendor back-lapping repair or fabrication?
The rejected wafers remained manufacturing scrap, so their original cost was removed from tax. Vendor back-lapping made test aids and was taxable processing measured by that charge.
Were drafting-only or pen-plotted drawings taxable when created from customer drawings, blueprints, sketches, and descriptions?
Yes when furnished alone. California treated drafting-only and pen-plotted output as taxable reformatting or physical-form conversion rather than original-information development.
Was converting customer drawings into editable mathematical CAD data a taxable data conversion?
No under the described facts. Editing, correction, computation, and raster-to-vector work produced new manipulable mathematical information, with the disk incidental.
Were closed-caption creation, reformatting, translation, encoding pass-throughs, tape dubbing, and tape stock taxable during the audited years?
Captioning, reformatting, translation, and encoding pass-throughs were removed from tax; historical tape dubbing, tape stock, and California equipment use remained taxable.
Did keeping a vessel in California for 18 months of repairs automatically defeat the out-of-state-use exclusion?
No. Repair time alone did not defeat section 6009.1; the key question was whether all California activity served storage, repair, and direct removal.
When could newsletters and display ads qualify as printed sales messages, and how did purchaser delivery, mixed distribution, and refunds affect the result?
Promotional newsletters and display ads could qualify if delivery conditions were met, but general-interest newsletters might instead be periodicals. Purchaser-delivered portions were taxable and…
Does driving, sailing, or flying a purchased vehicle, vessel, or aircraft directly out of California count as taxable use?
Not if it was the property's only California activity before solely outside use. Necessary stops could qualify; other activity did not. Sales tax was separate.
How long could a vehicle, vessel or aircraft remain in California before section 6009.1 direct-removal or storage treatment ended?
No fixed period controlled. Time was evidence; the reason for presence and actual California activity decided whether storage or direct removal stayed excluded.
What did California registration, time in state and activity show about section 6009.1 use when a vehicle, vessel or aircraft was bought here?
Registration and elapsed time were evidence, not fixed rules. Actual California activity controlled; direct removal or storage for it could qualify, but other use did not.
Could a copying service treat part of its direct bill for subpoenaed hospital records as a nontaxable statutory fee when the hospital charged it nothing?
No. When the hospital only made records available without charging the service, all of the copying service's direct charges to the requester were taxable.
Could a third-party copying service exclude a separately labeled statutory medical-record fee when the hospital made its records available without charging the service?
No under Staff Counsel's assumed facts. If the hospital only made records available and charged the copying service nothing, all amounts the service billed the requester were taxable regardless of…
Could a tuxedo lessor deduct separately stated alteration labor from taxable rental receipts?
No. The alterations were necessary to provide each tuxedo in the requested form, so the charges were part of taxable rent.
Was tax refundable when a prefabricated aircraft hangar later became a permitted improvement to real property?
No. A furnish-and-install sale would be construction work, but this hangar was sold for installation by the buyer or its contractor, so the entire retail sale remained taxable.
Were reproduction proofs delivered through diffusion transfers, negatives, or prints taxable in California?
No. California agreed that charges for those reproduction proofs were not taxable under the stated typography rules.
Were reproduction proofs taken directly from a typesetting machine and delivered to the customer taxable?
No. California agreed that the direct-output reproduction proofs described by the typographer were not taxable.
Could a houseboat move from a rental partnership to its partners and then to a new corporation without sales or use tax?
Yes for counsel's inferred two-step transaction under stated conditions. The pro rata houseboat distribution qualified under section 6281; the corporate transfer was nontaxable for proportionate…
Was a doctors' buying group merely a billing service when vendors shipped ophthalmic supplies directly to member doctors?
No. The group's payment obligations, approved-vendor system, group-volume discounts, and member agreements showed that it bought supplies for resale and was the retailer despite direct shipment.
Were a nondealer's charges taxable for painting custom murals on vehicles classified as new or used by time since first DMV registration?
No. Painting a mural was not treated as producing tangible property or as a production step, so the charge was nontaxable for both new and used vehicles.
How much of a federally allowed qualified-retirement-plan contribution could a nonresident partner deduct on a California return when the partnership earned income inside and outside California?
Only the portion tied to California-source earned income. The ruling multiplied the allowable federal deduction by California earned income divided by total earned income supporting the…
How did California tax repair parts when repaired property was shipped across state lines?
Out-of-state repair labor was not a California sale, but retailer-furnished parts shipped into California carried use tax; qualifying parts shipped out were interstate sales.
