Did selling 11 decoder boxes make a cable company's entire asset sale taxable?

No. Counsel treated cable service and the $4,295 decoder-box activity as separate businesses, so tax applied only to tangible property held or used in decoder-box sales. The source gives no final…

1990-03-19

Did a buyer's successor liability include the price of trucks used as capital assets in a trucking service business?

No. The trucks and tractors were capital assets of the service business, not inventory of the incidental truck-selling business. Successor exposure was limited to the $50,000 price allocated to…

1990-03-16

Were alfalfa seeds for sprouts and flax or cress seeds exempt from California sales tax?

Yes. Alfalfa sprouting seed qualified under the food-producing-seed rule, and flax and cress were exempt unusual foods unless labeled as food supplements.

1990-03-14

How did California determine whether tooling was sold for resale, sold at retail, or acquired by a manufacturer as a customer's agent?

Timing and ownership controlled: use before sale made the manufacturer's purchase taxable; sale before use shifted tax to that tooling sale; true agency put title directly in the principal.

1990-03-11

When did a pre-November 7, 1989 construction contract qualify for the temporary old-rate protection?

Specified materials needed fixed unit prices that included or stated the old 7% rate. Estimates were insufficient, and an unconditional termination right defeated relief.

1990-03-09

How did California tax large styrene letters manufactured and glued onto buildings?

The letters were fixtures. The installer owed tax on the manufactured fixture's Regulation 1521 cost price, not the entire furnish-and-install charge.

1990-03-08

Could a federal construction subcontractor avoid use tax on materials and fixtures because its contract described the property as machinery and equipment for resale?

No. Regulation 1521 controlled the classification; materials and fixtures bought ex tax and used in the work were taxable to the subcontractor.

1990-03-05

Which video-production charges did California treat as nontaxable services, taxable property, or taxable rentals under proposed Regulation 1529?

California exempted qualifying editing, filming, graphics, intermediate dubs, and modifications, but generally taxed blank tape, equipment rentals, props, artwork, and release copies.

1990-03-01

Was a clothing retailer's $20 club fee taxable when membership entitled customers to 20% off every purchase?

Yes. The fee was tied to anticipated retail purchases and was included in the retailer's gross receipts from tangible-property sales.

1990-03-01

Did latchkey and preschool relocatable buildings qualify for the factory-built school-building 40% rule?

No. Because they were not designed or intended as school buildings, furnish-and-install contracts were construction contracts taxed through the manufacturer's materials and fixtures, not its selling price.

1990-03-01

Did separate equipment and support agreements keep required consulting, training, troubleshooting, and startup services outside the taxable sale?

No. The agreements implemented one all-or-nothing proposal, so required support was part of the taxable property sale; only proven installation labor was excluded.

1990-02-28

Did a nonrecourse equipment-lease assignee become the lessor responsible for tax on rentals?

Conditionally yes. Without proof of financing or an earlier sale at inception, transferred title/rights and no recourse made the assignee the taxable lessor.

1990-02-27

Did California sales or use tax apply when a retailer mailed goods to an armed-forces APO or FPO address through a California postmaster?

No, under the cited rule, if the goods were mailed for forwarding outside California and the retailer kept the required address and mailing records.

1990-02-27

Did one rail sale-leaseback qualify as financing when the deal covered units originally owned by both a parent and its subsidiary?

Only partly. Parent-owned units qualified, but subsidiary-owned units did not because the subsidiary was not certain to regain ownership.

1990-02-23

Did delinquent lease late charges and property-tax reimbursements become taxable buyout price merely because they were paid when an option was exercised?

No. Charges already owed under lease regardless of option were not consideration for title; recommendation deleted Item E but left other issues.

1990-02-16

Were display cabinets made in Mexico exempt when the seller temporarily stored them in California and then shipped them to the buyer's out-of-state customers?

Yes under the stated seller-direct shipment. The California sale qualified for interstate exemption because the contract required carrier shipment out of state; direct Mexico-to-destination delivery…

1990-02-16

Was an interconnected parking-control system a resale of equipment or a construction contract?

It was a construction contract. The ticket, payment, barrier, detector, sign, card, and cashier components were integrated into the parking garage as materials or fixtures.

1990-02-14

Did a VCR manufacturer have to refund sales-tax reimbursement when it, rather than the retailer, refunded a defective unit's price?

No. Only the retailer could claim the returned-merchandise deduction, and only by refunding the full price plus sales-tax reimbursement itself.

1990-02-13

Were separately priced alcoholic or carbonated drinks exempt when sold at a qualifying religious organization's meal fundraiser?

No. The exemption covered qualifying meals and food products, not separately priced alcoholic or carbonated drinks; an admission charge did not defeat the meal exemption.

1990-02-07

Could a machinery seller preserve a returned-merchandise deduction after reducing the refund to recapture a lost quantity discount or overhead?

No. A refund may be reduced only for actual rehandling and restocking costs; withholding overhead or a lost quantity discount defeated the deduction.

1990-02-06

Could a successor corporation silently continue buying under its predecessor partnership's resale certificates?

No. It had to notify vendors; otherwise it could be treated as adopting the old certificates and owe use tax on property consumed after tax-free purchase.

1990-02-06

Was sales tax due when an equipment lessee exercised substantial purchase options after paying tax through purchase-price or rental methods?

Yes. Each option transfer was separate retail sale taxed on buyout price, whether lease property used purchase-price tax or rent-based use tax.

1990-02-06

What was the taxable measure when a company produced and sold compact discs for use as radio commercials?

Only the sale price of the unprocessed compact-disc medium; recording labor, services, production expenses, and intangible elements were excluded.

1990-02-05

Can resale inventory be used tax-free for 30, 60, or 90 days if it is later sold as new within a reasonable period?

No. Section 6094 provided no general tax-free period for intervening use. Use beyond demonstration or display was taxable even if the item was later sold as new, subject to the statute's specific…

1990-02-05

Can equipment held for resale be shown to sales and service personnel or tested for compatibility without creating taxable use?

Yes, on the described facts. Showing equipment features to sales or service personnel—without tearing the machine down—and testing whether the product itself was compatible with other equipment…

1990-02-05

Were customer mailbox charges taxable rentals of tangible personal property when the boxes were incorporated into the building?

No. Counsel treated boxes as building fixtures, so customers leased facility space rather than tangible personal property.

1990-02-01

Were fabric-design colorways taxable artwork or nontaxable services, and could unsupported resale and export claims remove the sales from tax?

Colorways and customer-site recoloring were taxable artwork and manufacturing aids. Unsupported resale or exemption claims failed, but penalty relief was recommended.

1990-01-31

How did California tax an out-of-state company's aircraft modifications performed by a California subcontractor using engines, nacelles, and struts?

New-aircraft modification was fabrication; used-aircraft work was likely repair. A property-free subcontractor fabricating for the retailer made no sale, while parts and delivery rules varied by use…

1990-01-30

Did expiration of the criminal fraud-prosecution deadline also prevent California from imposing a civil fraud penalty?

No. Section 7154 barred a late criminal prosecution, but section 6487's fraud exception still allowed the civil determination and fraud penalty.

1990-01-30

When was an aircraft-repair subcontractor the consumer rather than the seller of parts and materials?

When its parts and materials were ten percent or less of the total repair charge and were not separately charged, the subcontractor consumed them and tax applied to its purchase or use.

1990-01-30

Did using a California subcontractor for aircraft modifications make the prime contractor a retailer engaged in business in the state?

The 1990 opinion lacked enough facts to decide. Dedicated storage or authority for the subcontractor to take customer orders could create nexus.

1990-01-30

Was machining an engine head taxable when done to improve a new product's performance, and was the same machining taxable when restoring a used head?

Machining a new head to final performance specifications was taxable fabrication. Restoring a damaged used head to its prior specifications was repair.

1990-01-26

How were an installed mezzanine module and its storage shelving classified for California sales tax?

The mezzanine structure was material consumed by the contractor, while the prefabricated shelving was a fixture sold by the contractor and taxed under fixture-price rules.

1990-01-25

Were database-access charges taxable when the provider also supplied connection software without a separately stated charge?

Database access itself was a nontaxable service, but the software transfer could be taxable; a supported allocation was required or all charges risked tax.

1990-01-24

Were missing- and damaged-equipment charges taxable sales, and could the lighting lessor recover tax paid when it bought the property?

No sale occurred: the charges compensated loss or repair of the lessor's property. The lessor also could not recover its original purchase tax.

1990-01-18

When were an artist's supervision of student artwork and temporary church installations taxable fabrication, leases, or nontaxable consulting and installation?

Necessary control over fabrication was taxable supervision; advice without control was consulting. Temporary art transfers were leases, with true installation separable from fabrication.

1990-01-12

When could an artist exclude installation charges from taxable rent for temporary artwork placed in churches?

Only charges for attaching already completed artwork were excludable; creating or unifying the artwork during attachment was taxable fabrication.

1990-01-12

Were church contributions taxable rent when an artist supplied temporary artwork in exchange for whatever amount the church chose to pay?

Yes. A church's agreement to pay something created taxable rent even if its amount was uncertain; a truly voluntary later gift was different.

1990-01-12

When was an artist's supervision of student-created church artwork taxable fabrication rather than nontaxable consulting?

Supervision was taxable when necessary to and controlling fabrication; advice without control over others' fabrication was nontaxable consulting.

1990-01-12

Was temporarily furnished church artwork a gift when there was no suggested minimum and no obligation to pay, even if the church later contributed money?

Yes, if there truly was no payment agreement. A later voluntary contribution would not turn the transfer into a taxable lease, but the artist would be consumer of property furnished as a gift.

1990-01-12

Were logo-printed presentation folders exempt printed sales messages or containers when used to ship promotional literature?

The folders were not printed sales messages, but their sale was exempt when they actually served as containers shipped with qualifying promotional literature; a folder holding only one piece was taxable.

1990-01-08

Were liqueur-filled chocolates exempt candy when their labels said sales to underage buyers were unlawful?

No. The chocolates were taxable because they contained enough alcohol to be alcoholic beverages, which were excluded from the food-products exemption.

1990-01-05

Which home-video promotional items qualified as printed sales messages, and how were novelty items and folders taxed?

Catalogs, brochures, pamphlets, and paper posters qualified, but displays, visors, clocks, calendars, and novelty items did not. Folder and marketing-aid treatment depended on use and reimbursement.

1990-01-04

Were hourly in-store computer-use charges taxable leases when use lasted under one day and cost less than $20?

No. Under historical rule, under-one-day on-premises use below $20 was not lease; provider was consumer and tax generally shifted to acquisition/use.

1990-01-03

Who owed California tax when a Kentucky auction sold mining equipment that remained physically located in California?

On the assumed facts, the auctioneer did not owe California sales tax and was not treated as engaged in business. But the California owner's delivery made the owner the taxable retailer under section 6007.

1990-01-03

Did paying California colleges a royalty to distribute sponsored notepads make the out-of-state producer collect use tax from the sponsors?

Yes under the historical rule applied. The colleges delivered the notepads under the producer's authority and were its California agents, so it collected use tax measured by the pads' sales price.

1989-12-20

Were off-the-shelf telephone channel-bank units installed for the U.S. government exempt from California sales tax?

Yes. They were machinery and equipment: the contractor's purchase was for resale, and its sale to the U.S. government was exempt because title passed before any contractor use.

1989-12-18

Did a purchasing business need a California seller's permit when it bought solely for resale and foreign export to an affiliate?

No under either stated route. A true agent made no own-account purchases or sales. A principal buying for its own account needed no permit only if every sale was for foreign export; it had to issue…

1989-12-14

Were forced payments added to cooperative members' hearing-aid purchases taxable even though they built working capital and could later be refunded?

Yes. The required payments were part of what purchasers paid for merchandise, regardless of the cooperative's use or later return of the money.

1989-12-14

Did transferring only the beneficial interests in aircraft owner trusts to affiliated corporations trigger California sales or use tax?

No. After reviewing a representative trust agreement, California found the transfers were not taxable, assuming the trusts were not revoked first.

1989-12-11

Were charges to develop a training course taxable when the designer delivered one participant guide, leader guide, text transparencies, and video script?

No. California treated the course development as a service and the single guides, text transparencies, and video script as incidental deliverables.

1989-12-08

Were the sale and leaseback of a fixed steam-generating plant taxable transfers of tangible personal property?

No. Without contemplated severance, the plant sale transferred a realty interest and the whole-building leaseback remained real property.

1989-12-08

Did a steam-generation plant sale and leaseback become taxable because the land was not sold and the structure contained fixtures?

No. The fixed plant was an interest in realty because no severance was planned, and its later lease remained a lease of realty. The revised recommendation granted the refund.

1989-12-08

Which charges were taxable when new equipment was dismantled for shipment, shortened to satisfy a height rule, reassembled, and installed?

Shortening new equipment was taxable fabrication. Independent shipping disassembly and reassembly were nontaxable, as was actual attachment after the modified equipment was complete.

1989-12-07

Did an 18-pound portable pacemaker become an exempt body-worn prosthesis because electrodes attached it to the patient?

No. California found the pacemaker portable but not designed to be worn, and the attached electrodes did not make the full unit body-worn.

1989-12-06

Did an 18-pound temporary pacemaker qualify as a body-worn prosthesis because electrodes attached it to the patient?

No. California found the machine portable but not designed to be worn, and the electrodes did not make the complete unit body-worn.

1989-12-06

How did California distinguish the mobile barge equipment from the submerged pipeline in an experimental federal sand-dredging facility?

The barge and mounted equipment were not improvements to realty, but the submerged pipeline remained a real-property improvement consumed by the contractor.

1989-12-05

Did the experimental and partly removable design of a federal sand-dredging facility make the audited pipeline, pilings, and platforms nontaxable personal property?

No adjustment was allowed. The barge equipment was not realty, but the submerged pipeline remained an improvement and the contractor did not prove resale before use of the other items.

1989-12-05

Was repairing a federal dry dock attached to a pier and utility systems a real-property construction contract under Regulation 1521?

Yes. The dry dock was treated as an improvement to realty, so the federal construction contractor consumed the materials and fixtures it furnished.

1989-12-05

Was repairing a federal dry dock attached to a pier and utility systems a real-property construction contract under Regulation 1521?

Yes. The dry dock was treated as an improvement to realty, so the federal construction contractor consumed the materials and fixtures it furnished.
