Were charges for scanning legal documents onto disks excluded when the provider also created a searchable index?

Yes, except for duplicate copies. Creating the word index was customer-data processing, making the combined copying-and-processing transaction nontaxable.

1993-01-29

Can aircraft flights patrolling powerlines or pipelines count as common carriage for California's aircraft exemption?

Only when the flight actually transports a person or property for hire and meets the other common-carrier rules. Merely flying the line without transporting either does not qualify.

1993-01-28

Could a company combine 14 used-computer dispositions from one repossession and treat its later $700,000 asset sale as occasional?

No. Staff ultimately counted 15 used-computer sales averaging more than $1,000 within one year, treated the $700,000 asset sale as part of that series, and denied occasional-sale treatment.

1993-01-27

Were meals sold directly to students by a school's outside food-service operator exempt as meals sold by the school?

No. The operator set prices and treated customer receipts as its own sales, so it—not the school—sold the meals and the student-meal exemption did not apply.

1993-01-25

Were charges for creating a manuscript index taxable when the contractor delivered one floppy disk, and what about related management and messenger fees?

No. Indexing was a service and one delivered disk was incidental; the official annotation also treated connected management and messenger charges as nontaxable.

1993-01-22

Was travel time between a custom cabinet shop and the job site a nontaxable installation charge?

It depended on cabinet classification and contract form. For fixtures, travel could be installation only when its sole purpose was installation; material-contract charges were already nontaxable.

1993-01-21

How did California tax a cosmetics manufacturer's sales through independent distributors, including resale certificates, personal-use products, and membership fees?

Valid permitted resellers reported their retail sales; sales to unpermitted or consuming distributors were taxed at the manufacturer's price. After written section 6015 notice, the manufacturer owed…

1993-01-20

How did California tax artwork bought under resale certificates and transferred to an affiliate for reproduction?

The transfer was a taxable lease, with all royalties and license fees included in rent. Photographing the art instead created taxable use plus a taxable negative sale.

1993-01-20

Was a cosmetics distributor's initial membership fee taxable when it included a manual, brochure, and videotape?

Yes. The fee purchased tangible materials; a renewal fee without property was nontaxable only if it met all three conditions stated in the letter.

1993-01-20

How did California calculate whether a fishing vessel was used principally outside state territorial waters?

Compare outside-water time with inside-water time across all actual fishing operations, including travel to and from fishing grounds. Outside time must be greater. Storage and idle time in…

1993-01-15

Could a subsidiary transfer all operating property and liabilities to Newco, then spin Newco through the corporate chain to the same public-company shareholders without tax?

Yes, conditionally. The January 15 letter treated the proposed transfer as exempt because all business tangible property moved and at least 80 percent ultimate ownership would remain unchanged,…

1993-01-15

Could California levy life-insurance interest or dividends owed by an out-of-state insurer doing business in California to out-of-state taxpayers?

Yes. Staff said the insurer had to comply because it did business through California agents, and state law did not exempt policy dividends or interest from garnishment.

1993-01-15

Were meals sold to state-prison inmates exempt as meals furnished to residents of an institution?

No. A prison was not an institution within the statute's defined exempt categories, so inmate meals—and snack foods included in those meals—were taxable.

1993-01-14

Was furnishing a mixer truck, driver, cement, and labor to solidify a customer's hazardous waste an equipment lease or taxable fabrication?

It was taxable fabrication, not a lease. The contract supplied truck and mandatory driver as a unit without transferring possession/control.

1993-01-13

Did later out-of-state shipment exempt logo merchandise already sold and billed while held in the seller’s California warehouse?

No under the assumed contract. Title passed when the goods entered the warehouse, and the contract did not require out-of-state shipment, so later customer-directed delivery did not exempt the…

1993-01-13

Were diagnostic reagents applied only to removed tissue samples exempt as prescription medicines in California?

No. California treated the reagents as taxable because they were applied only to samples removed from patients and never to a patient's body.

1993-01-11

Were the described intravenous sets and temporary infusion catheters exempt as prescription medicines in California?

No. California treated the IV sets as taxable devices and found no exemption for the temporary catheters used to infuse medication or nutrients.

1993-01-11

How did HMO payment, ownership, and no-cost patient use affect medicines, durable equipment, oxygen systems, diaphragms, and hearing aids?

Insurance payment alone did not change taxability, but an HMO retaining ownership and providing equipment at no charge was the taxable consumer rather than the patient.

1993-01-08

How could California assert an increased determination at or before a taxpayer's hearing, and what written-notice formalities applied?

An increase needed no special form and could first be announced orally at the hearing if the taxpayer was notified; statutory notices still had to be written and properly served.

1993-01-07

Were a foundation's annual report and twice-yearly newsletter exempt printed sales messages or nonprofit periodicals?

They were not printed sales messages and were too infrequent for the post-October 1992 periodical rules, but printing sold from November 1991 through October 1992 was exempt.

1993-01-07

Were a foundation's annual report and twice-yearly newsletter exempt as printed sales messages or nonprofit periodicals, and did the historical period matter?

They were fundraising, not printed sales messages, and too infrequent after October 1992; November 1991–October 1992 printing was exempt.

1993-01-07

Were charges for wedding videography, editing home videos, and duplicating customer tapes taxable?

Yes. Private noncommercial videos were not qualified motion pictures, and producing, editing, or duplicating them was taxable even with customer-supplied equipment.

1993-01-07

Can a taxpayer rely on an older California FTB Legal Ruling without checking later statutes, regulations, administrative guidance, and court decisions?

No. FTB said every Legal Ruling states its official conclusion under the law existing when issued, but later law or decisions may supersede all or part of it. Reliance on a ruling superseded by a…

1992-12-28

Were color overhead transparencies made from a client's outline notes taxable, and how did that differ from producing one transcription or multiple copies?

The transparencies and total charge were taxable because the physical output was the true object; one original transcription was a service, but additional copies were taxable.

1992-12-21

Could an out-of-state optional-warranty company give a California appliance repairer a resale certificate for repair parts?

No. The warranty company consumed the parts, so the California repairer made taxable retail part sales and separately stated nontaxable labor.

1992-12-21

Was the full charge taxable when a word-processing business used a customer's hard-copy outline to produce color overhead transparencies?

Yes. The physical transparencies were the true object, so the entire charge was taxable whether or not they had cardboard frames. The same letter treated one audio or hard-copy transcription as a…

1992-12-21

Were washers and dryers exempt as an occasional sale when owners sold a combined snack-bar and laundromat business?

No. Legal Division treated the same-address, unseparated snack bar and laundromat as one seller-permit retail business, so its washers and dryers were taxable. The source supplies no amended-return…

1992-12-21

Did making maintenance optional for a few powerful or preferred customers make it optional for every buyer?

No. Optionality was transaction specific; a customer required to buy maintenance faced a taxable mandatory agreement even if favored customers did not.

1992-12-18

Is a maintenance agreement optional merely because preferred customers can buy or lease equipment without it?

No. Mandatory status was transaction-specific: a customer's required maintenance was taxable even if favored customers got different terms.

1992-12-18

Were computer-maintenance charges optional and excluded from taxable rent when the lessee could choose between two lessor-provided plans?

No. Choosing between two lessor plans was not optional maintenance because every choice required buying maintenance from the lessor.

1992-12-18

Does an insurer become the lessee of medical equipment merely because it pays the provider for a covered patient's rental?

No. Under the letter's assumption, the patient lease carried use tax even if insurance paid; a direct insurer lease put sales tax on the lessor.

1992-12-18

Were separately stated chemical-toilet cleaning charges excluded from taxable rent when the lease said service was optional?

Yes. The revised lease made cleaning optional from the lessor, and customers could hire another qualified provider without breaching it.

1992-12-18

Did an insurer become the purchaser or lessee merely because it paid a patient's bill for home-therapy equipment?

No. The patient remained the purchaser or lessee, so ordinary tax rules applied. A direct insurer contract instead shifted the applicable levy to sales tax on the provider.

1992-12-18

Who owed California use tax on MTE vehicles rented directly to the U.S. Navy?

The lessor, not the Navy. A contract could reimburse the lessor's cost, but invoices should not represent that the federal lessee itself was being charged tax.

1992-12-16

Was a later sale of bottled-water pallets taxable when the customer decided to keep them for internal store transport?

Yes. The customer bought the pallets for its own internal use, and the water seller had already used them as returnable containers before the later sale.

1992-12-16

How was a lump-sum and royalty contract taxed when it transferred technical materials plus the licensed right to reproduce technology in integrated circuits?

Only the value of transferred tangible materials was taxable; the amount attributable to federally protected manufacturing and sales rights was nontaxable intangible property.

1992-12-15

Did FAR 52.216-7 or FAR 52.216-13 accelerate federal title merely because they governed allowable cost and payment?

No. Neither clause passed title before contractor use; cost-reimbursement contracts needed FAR 52.245-5, while facilities contractors remained consumers.

1992-12-14

Was the Edge Bar exempt after Proposition 163 repealed California's temporary snack-food exclusion?

Yes. Beginning December 1, 1992, food bars were again nontaxable, and a bar was not one of the product forms covered by Regulation 1602(a)(5).

1992-12-14

Was a software-upgrade promotion a true discount when customers had to surrender old software licenses?

No on the stated records. The required surrender and agreed value made it a trade-in, so that value stayed in taxable gross receipts unless the contract clearly separated a discount.

1992-12-14

Could a software seller exclude an agreed trade-in value by describing part of the upgrade promotion as a discount?

No. The agreed software trade-in value stayed in taxable gross receipts because the contracts did not clearly provide both a trade-in and a separate discount.

1992-12-14

Could a California designer use a historical percentage to classify computer-design charges as preliminary art?

No. The designer had to identify actual physical proofs prepared before finished-art approval and keep client-dated approval or similar evidence; a historical 60% allocation was not enough.

1992-12-14

Would tax apply when a company moved its one-half airplane interest to a new corporation solely for that corporation's first-issued stock?

No, if the commencing corporation's first-issue stock was the sole consideration for the one-half aircraft interest. Counsel emphasized that anything else received would be taxable at its money…

1992-12-11

Were electronically delivered consulting, text, software, and information sold through a California-hosted online marketplace taxable, and could the platform be the retailer?

Electronic transfers without tangible property were nontaxable; a mailed hard copy made the full charge taxable, while the platform's retailer status remained fact-dependent.

1992-12-09

Which listed supports, braces, splints, and rehabilitation products did California treat as orthotic devices?

California treated many fully worn corrective supports and braces as orthotic devices, but taxed appliances, accessories, and insufficiently described products.

1992-12-09

Did a cervical pillow and a bed-attached balanced suspension sling qualify as exempt orthotic devices in California?

No. California taxed both products because neither was fully worn on the patient: the pillow rested on the bed and the sling attached to the bed.

1992-12-09

Which sales by a nonprofit youth summer camp were taxable?

The meal portion of camp fees, regularly operated camp-store souvenirs, and firewood were taxable; snack-food treatment and school or youth-group exceptions depended on separate rules.

1992-12-09

Did HUD-code housing units without California housing approval and insignias qualify for the factory-built-housing partial sales-tax exemption?

No. Without the required approval and insignia, the units were neither qualifying factory-built housing nor mobilehomes, so ordinary retail and construction-contractor rules applied.

1992-12-09

How did California treat electronically delivered information, remote-access fees, storage, and mailed hard copies?

Electronic delivery, remote access, connection, and storage were excluded on the stated assumptions; mailing a hard copy made the entire information charge taxable.

1992-12-09

Were customer-specific language translations taxable when transferred on floppy disks, and what happened with extra copies or translations sold to a broader market?

A single-customer translation was a nontaxable service even on disk, but extra copies and standardized translations offered to the public were taxable property sales.

1992-12-08

Did an Associated Students directory qualify as a printed sales message when 276 of its 708 pages were advertising?

No. Advertising did not exceed half of the printed area, so the directory failed the principal-purpose test and the assumed printer's sale was taxable.

1992-12-08

Were standardized monthly county real-estate reports nontaxable information services, taxable tangible property, or exempt subscription periodicals?

Paper or disk reports were property sales but could qualify as mailed periodicals after November 1, 1992; electronic delivery was nontaxable.

1992-12-04

Was a California sale of spare parts to Canada's defence department exempt because the seller also happened to be a United States contractor?

No. The seller's unrelated federal-contractor status did not matter, possession transferred in California, and the source found no Canadian-government exemption.

1992-12-02

Could crude-oil emulsion breaker E-4161 be bought for resale because it remained with the oil after water and brine were removed?

Apparently not. Its purpose was removing water or brine, so it was a taxable manufacturing aid unless it had a specific beneficial function after processing ended.

1992-11-24

Was a land surveyor's charge taxable when the surveyor measured a site, prepared a drawing from field work, and gave the client a copy?

No. The land survey was the true object, and the drawing was only an incidental transfer of tangible personal property.

1992-11-23

Was a medical center's physician handbook a printed sales message when it sought referrals but functioned as a department and physician reference guide?

No. California treated the handbook as a directory and reference guide to services and physicians, not a publication principally advertising or promoting services.

1992-11-19

Was a post-merger dropdown of 75 percent of an acquired leasing business's assets and liabilities to a subsidiary also nontaxable?

No. Regulation 1595(b)(3) protected the statutory-merger step, but the later dropdown was a separate sale because first-issue stock and recorded intercompany debt or assumed liabilities were…

1992-11-19

Did California teachers administering an out-of-state seller's school book club create a use-tax collection duty?

Yes. The appeals recommendation treated teachers who took orders, collected payments, and delivered books as the seller's California agents.

1992-11-19

Was powdered Nutri-15 Plus protein supplement exempt as a California food product?

No. California taxed the powdered product because its label called it a protein supplement and gave directions for using it in a weight-loss program.

1992-11-18

Could a vehicle export remain tax-free when the seller could not be listed as bill-of-lading shipper because the buyer containerized many items?

Yes, conditionally: seller-to-intermediary delivery, written no-diversion/no-cancellation terms, intermediary confirmation and foreign-shipment proof were required.

1992-11-18

Which low-emission vehicle and retrofit-device amounts qualified for the section 6356.5 exemption?

Properly documented incremental new-vehicle costs and labeled retrofit devices were exempt, but a dealer's later sale of its retrofitted used vehicle was fully taxable.

1992-11-13
