Was writing advertising and brochure text taxable when the author delivered only typed words or a computer disk and someone else created the artwork?
No. Original text without graphics was a nontaxable author service, but artwork and extra copies of the original work would be taxable.
Were a copywriter's charges taxable when the writer delivered original text by typed page or computer disk but did no layout, graphics, or finished artwork?
No. Text-only original copy was an author's nontaxable service even when delivered on a disk. Charges became taxable for copy including graphics or artwork, or for reproductions of the original work.
Was a three-percent discount on receivables sold without further recourse a deductible bad debt?
No. The recommendation treated the transfer as financing, the discount as interest expense, and neither fact as a worthless-account deduction.
How did California tax percentage and additional delivery charges on orders containing taxable and nontaxable food products?
Delivery followed the related food sale: taxable before-sale delivery for taxable items, nontaxable for exempt items, and separately allocated on mixed orders.
Were drawings prepared from architects', engineers', or other clients' specifications taxable architectural services or sales of tangible property?
They were taxable sales of drawings, not architectural services; only qualifying plans prepared under the statutory exception described could receive service treatment.
Did California settle a tax debt by cashing a smaller check marked as payment in full?
No. Staff said tax obligations arise by statute, not contract, so a restrictive endorsement could not create an unauthorized settlement; statutory settlement procedures controlled.
Did a payment-in-full endorsement bind California when the Board deposited a taxpayer's partial-payment check?
No. Staff said tax collection was statutory rather than contractual, so depositing the check could not create a compromise outside the authorized settlement programs.
Did an out-of-state contractor need a California seller's permit solely to install customer-provided signs and furnish minor construction materials?
No under the opinion's assumptions: the customer supplied fixture signs, the contractor performed no prefabrication, and anything it furnished qualified as consumed material. Prefabrication or…
Did an out-of-state contractor need a California seller's permit when it installed customer-provided sign fixtures and bought only incidental construction materials?
No, if it performed no pre-installation fabrication and furnished only materials it consumed. Taxable sign fabrication or furnishing fixtures or equipment required a permit.
Were semiconductor carrier tapes and reels exempt containers or merely incidental to a service when used to feed chips into assembly machines?
No. The tapes and reels were taxable tangible manufacturing aids, not exempt nonreturnable containers, and chip placement and inspection were incidental to their sale.
Could a photo finisher avoid California tax on an internegative and print shipped to an out-of-state customer after using the internegative to make the print?
The outbound print and internegative sale could qualify if the contract, shipment method and records met the interstate rules, but using the internegative in California first made its purchase or…
Could repair parts installed on government-, contractor-, or lessor-owned vehicles be sold for resale to the United States under a general accelerated-title clause?
Yes when the federal contract covered those parts before use and the parties accounted for them that way; otherwise the contractor consumed the parts.
Was an HVAC control-system provider a construction contractor when it selected, assembled, programmed, and supplied controls but only supervised another contractor's installation?
No. Without a contractual duty to install, it sold tangible personal property, and tax applied to the full charge without deduction for engineering or programming work.
Was an uninterruptible power supply installed at an Air Force base machinery and equipment that could be bought for resale, or a taxable fixture?
It was a fixture because it was essential to the base's power system and intended as a permanent real-property component; its conduit and wiring were also taxable.
Were a mall food-court juice bar's fruit juice, ice cream, and yogurt sales taxable under the 80/80 rule?
Yes. All four food-court units under one permit were combined; 91% of sales came from meals and hot food, so juice-bar sales were taxable except allowed resale sales.
Did a 1994 California memorandum tax a food-contamination inspection that usually delivered only a report?
No, under the stated facts. The report service was the true object, and film supplied only when contamination was found was incidental if no additional charge applied. The provider consumed property…
Were a section 501(c)(3) foundation's quarterly member periodicals exempt despite one paid advertiser, and what about copies sold to nonmembers?
Member and contributor distributions qualified under section 6362.8(b)(1); nonmember sales were not exempt if copies contained paid commercial advertising.
Was a $199 lump-sum fee for weight-loss counseling, classes, reference materials, and audio and video tapes taxable?
Yes. On the stated facts, staff counsel attributed the large increase to the tapes and treated the entire lump-sum fee as taxable receipts.
Did a 1994 California memorandum tax a contract whose ultrasound or computer-assisted topography images became the report?
Yes. With no professional interpretation or conclusion, the paper image itself was the report and the contract's true object was tangible personal property. The full charge was taxable without…
Did jewelry stores prove their prices included sales-tax reimbursement by producing Japanese-language signs and inconsistent invoices after the audit?
No. The evidence did not show the signs were posted during the audit period, and invoices sometimes added tax separately, contradicting a consistent tax-included practice.
Was an independent contractor's labor taxable when producing newspaper paste-ups containing type and artwork?
Yes. Combining typed matter with illustrations or other artwork into a paste-up was taxable fabrication labor, and the publisher used the paste-up as a manufacturing aid.
Who consumed structural-steel materials when a separate joint venture contracted to furnish and install them but its venturers performed the fabrication and erection?
The joint venture consumed materials because it owed both duties. A venturer doing fabrication alone made a taxable sale; a venturer obligated to fabricate and install consumed its work.
Was only two-thirds of a horse auction taxable when a one-third partner bought the partnership's horses, and was a catalogue logo composed type?
No on both claims. The partnership-to-partner transfer changed ownership, so the full price was taxable, and the California-bred logo was taxable artwork rather than composed type.
Did an aircraft and its later corporate transfer qualify when FAA authorization for that aircraft came late in the 12-month use periods?
No. Pre-certification flights could not count as common carriage, and the documented post-certification hours were insufficient. The corporate transfer's tax measure was reduced by $550,000.
Did a letter submitting the seller's final return and notifying California of an asset purchase count as a request for a tax clearance certificate?
No. A clearance request had to be clear and unambiguous, and the letter never asked for a certificate. Successor tax remained due, but California waived the predecessor's penalty because the buyer…
Were charges for editing requested television-news segments onto videotapes taxable, and did alleged oral Board advice excuse the tax?
The full charge was taxable because customers bought finished videotapes, not editing alone; alleged oral advice did not satisfy the written-advice requirement for relief.
Could specially ordered advertising inserts delivered to magazines qualify as exempt printed sales messages for both subscription and newsstand copies?
Yes, if the inserts were substantially promotional and readers received them at no added cost. The magazine itself did not need to be an exempt periodical.
Does mistakenly depreciating a truck and trailer create use tax when convincing evidence shows they were bought for resale and never otherwise used?
Not necessarily. The Board recommended no use tax because the depreciation was erroneous and produced no tax advantage, convincing evidence showed the vehicles were bought for resale, and the…
Could gasoline stations claim refunds of the unconstitutional SDJF district tax when their pumps said all taxes were included in the price?
No. The pump notice showed customers reimbursed the tax through included pricing, so customers bore the economic burden and received SB 263's tax-credit remedy.
Did UPS delivery from a printer to an affiliated directory-distribution company make the printer's sale exempt?
Not by itself. The affiliate also had to be truly separate from the purchaser and qualify as a compensated mailing house that prepared property for mailing.
Were ski rentals under $20 and under one day excluded from lease tax when customers took the equipment from an independent shop to nearby resorts?
No. The short-use exclusion required use on the lessor's premises, so ex-tax skis taken to resorts produced taxable rental receipts.
Did a California publisher owe use tax on free catalogs bought out of state, stored in its California warehouse, and later mailed nationwide?
Yes. The publisher completed the gifts when it handed catalogs to carriers or USPS in California, so its functional use occurred here; storage-for-out-of-state-use and 90-day arguments did not apply.
What evidence did California use to distinguish a property investor or collector from a retailer holding goods for resale?
Investment and collection purchases were retail sales. California listed eight business indicia, including public sales activity, records, suppliers, transaction volume, permits, priced merchandise,…
Did agency language make an advertising company a true purchasing agent when it used resale certificates, marked up vendor costs, and transferred client-review layouts?
No. Its conduct showed retailer status, and physical delivery transferred title to the layouts despite delayed-title language; art-direction charges required reaudit.
How is tax measured when a video-rental business lets employees borrow rental tapes for free?
On these facts, tax was measured by fair rental value for each employee loan—not the tapes' purchase price. The videos remained held for continuing taxable rentals, and occasional free employee use…
Could a cabinet contractor recover California tax paid on materials later used to build cabinets piece by piece at Nevada job sites?
No. The cabinets were not prefabricated fixtures under the historical 90-percent test, so the contractor consumed the materials and could not claim tax-paid purchases resold.
Did free technology publications qualify as periodicals or printed sales messages, and how did California measure their advertising content?
The periodical exemption applied conditionally; Net Age was not a printed sales message because only 9 of 19 pages were advertising.
Did sales tax apply when a mold contract was canceled before any property or title was transferred?
No. With no transfer of property or pre-delivery title passage, no taxable sale occurred; the fabricator could still owe use tax on materials bought for resale.
Was a custom-fitted prescription legging orthosis exempt from California sales tax as a medicine?
Yes. California treated the prescribed legging as an exempt orthotic device because it supported the leg's internal venous and lymphatic structure and was fully worn on the patient.
Were the Multicom 500 and Lympha Press Mini exempt orthotic devices because patients wore their sleeves or leggings?
No. California taxed both compression systems because hoses connected the worn sleeve or legging to an external pump, so the complete device was not fully worn on the patient.
Was a ticket broker's event guide an exempt periodical or printed sales message when its schedules were intended to drive ticket sales?
The schedules counted as advertising, so the guide was not an exempt periodical. Printed-message exemption depended on delivery to an independent distributor rather than the buyer.
Was a ticket broker's event schedule an exempt periodical or printed sales message, and did the printer's delivery method change the result?
The schedule was advertising intended to induce ticket purchases, so the publication failed the periodical test; printed-sales-message treatment depended on delivery to an independent distributor…
Was a leg strap used to secure an indwelling Foley catheter exempt from California sales tax?
Yes. California treated the strap as an exempt related supply because it secured an already-exempt Foley catheter to the patient's thigh.
Were sales of Amino Acids Pure Muscle Building Formula and Amino 1000 capsules taxable when marketed as nutritional supplements for exercise?
Yes. Capsule form, nutritional-supplement labeling, and the stated protein-maintenance purpose placed the products within the taxable supplement rule.
Were sales of Fat Burners and Advanced Formula Fat Burners taxable when the tablets and capsules were designed to reduce fat and develop lean muscle?
Yes. Their tablet or capsule form and stated fat-reduction and muscle-development purpose placed them within the taxable dietary-supplement rule.
Was tooling sold to a foreign customer exempt when the California manufacturer kept it after full payment and might use it before any export?
Not without a contractual foreign-delivery duty and actual export before functional use. Making only test articles did not by itself defeat a qualifying exemption.
Were Juice Plus+ capsules exempt when their label described fruit-derived ingredients but did not call them supplements or claim a vitamin, mineral, protein, or calorie purpose?
Yes. The 1993 label did not call Juice Plus+ a supplement or show a covered nutritional-intake purpose, so California treated it as exempt food.
Did a furniture retailer violate section 6205 by advertising no sales tax, and could it still report the sales as tax-included?
The ad did not violate section 6205 because that restriction applied to use tax. But without a valid tax-included notice, the retailer could not back tax out of its prices.
Was an aircraft truly leased to a common carrier when the owners retained scheduling approval and control over the aircraft and pilots?
No. The agreement did not transfer possession and control to the carrier. Owner scheduling approval, pilot control, and operating records showed that the owners remained the operators.
Who owed tax on an oil company's aircraft-refueler truck sales before and after the July 3, 1984 registration exemption?
Before July 3, 1984, the registered vehicles triggered direct use-tax payment by buyers. After section 4021 removed registration, the seller owed sales tax on the refueler sales.
Could a California supplier accept resale certificates from the in-state recipients of drop shipments for an out-of-state reseller without California nexus?
Yes. Timely, valid certificates accepted in good faith from the California recipients could relieve the supplier, whether delivered directly or through the out-of-state reseller.
Could a California drop shipper accept resale certificates from the out-of-state buyer's California customers?
Yes, but it was not required to. Without certificate protection, the California deliverer was deemed retailer when the out-of-state seller made a retail sale.
Were calligraphy charges taxable when lettering customer-furnished property, and did the same rule apply to addressing items for mailing?
Calligraphy was taxable artwork even on customer-furnished property, but hand or mechanical addressing solely for mailing was nontaxable.
Were calligraphy charges taxable when the customer supplied the paper or other item being lettered?
Yes. California treated handlettering as artwork and taxable fabrication even on customer-furnished items, except for addressing done for mailing.
Was heavy equipment still leased when it required a licensed operator but the customer could hire an independent operator instead of the owner's operator?
Yes. Customer could hire an independent licensed operator, so existing ex-tax equipment was leased and taxed on rents; future same-form property could use purchase-price tax.
Were fees for processing customer diaries or logs into hard-copy cost and expense summaries taxable?
No. The hard copy was incidental to processing customer-furnished information. The provider consumed its materials, but separately charged materials or extra copies were taxable.
Were training charges taxable when sold with computer programs and hardware?
Mandatory training was taxable even if separately stated. Genuinely optional training contracted for at a reasonable, separately stated price was nontaxable.
How did successor liability apply when a company sold 90% of its business, kept 10%, and planned a later sale of the remainder?
The first buyer was liable absent clearance or withholding, though the Board lacked facts to decide whether an auditor's copy of the agreement started the three-year limit. A later buyer of the…
Was a photographer's sale exempt when an advertising firm claimed to buy as agent for the National Potato Promotion Board?
Potentially, but the facts did not establish agency. The sale was exempt only if the firm met every regulatory agency requirement or resold the photographs before use. The photographer could be…
Was labor taxable when assembling customer-furnished electronic kits or repairing previously assembled, used computers and printers?
Kit assembly was taxable fabrication because it completed production. Labor merely restoring used computers and printers was nontaxable repair, though repair parts remained taxable.
