How did California tax an optional road-hazard warranty that repaired tires free or replaced them for a prorated customer charge?
The warranty fee was nontaxable, but the retailer consumed the warranty-covered part of a replacement tire and made a taxable sale of the prorated part charged to the customer.
Could a service provider offset tax charged to customers against use tax on property it bought for resale but consumed while providing the service?
Yes, transaction by transaction, for reimbursement collected before it knew the service was nontaxable. Later collections could not offset its use-tax liability.
Were charges for vehicle safety and emissions inspections, including the inspection sticker, subject to California sales tax?
No. The inspection was nontaxable labor, and the sticker was a record of the inspection rather than a sale of tangible personal property.
Could separately stated customization make the entire prewritten-software transaction nontaxable when it exceeded half the total price?
No. The itemized customization was nontaxable, while the remaining monthly charge required its own analysis and could not borrow the separate amount.
How should a repair shop tax an overhead or disposal charge connected with taxable parts and nontaxable labor?
Tax the full charge if it relates only to parts, exclude it if it relates only to nontaxable labor, and prorate a general overhead charge using the parts-to-labor ratio.
Were noncarbonated flavored waters, mineral waters, soft drinks, and canned iced teas exempt, and what if a product such as Koala Springs was actually carbonated?
The described noncarbonated, nonalcoholic drinks were exempt food products, but a product shown to be carbonated was taxable under the rule then applied.
Did an insurer's payment and resale certificate turn a medical supplier's direct sale to a patient into a tax-free resale?
No. California treated the transaction as a direct retail sale from the medical supplier to the patient; the insurer's payment did not make the insurer the purchaser for resale.
Did church nonprofit or federal income-tax-exempt status create a general California sales-tax exemption?
No. Retail sales by and to a church were generally taxable unless a specific California sales-and-use-tax exemption applied.
Was a graphic designer's full charge for camera-ready newsletter art taxable when delivered on paper or computer disk?
Yes. Typed matter combined with artwork was a taxable sale, including typography charges, and delivering the layout as a computer file on disk did not change the result.
Was a two-to-eight-week espresso-machine trial a nontaxable demonstration when the customer paid 40 cents per cup, including 15 cents for beans?
No. The paid trial was a taxable lease, with tax on the 25-cent machine-use portion per cup; the 15-cent bean charge was separately resale or exempt food.
Did firewood sold to a restaurant chain for cooking pizzas qualify for the section 6358.1 waste-by-product fuel exemption?
No. Firewood can be a forest-operation waste by-product when produced incidentally, but a restaurant cooking pizzas was not an industrial facility. That purchaser requirement failed regardless of…
How did California tax copper cladding fabricated for new residential hoods when attachment occurred before or after the hood became real property?
Before real-property attachment, the cladder made a taxable fabricated-property sale. After attachment, the cladding was material consumed under qualifying contractor billing.
Were monthly charges for placing free advertising postcards in restaurant racks taxable, and who owed tax on the cards and racks?
The client charges were nontaxable advertising services if the firm kept ownership of the postcards; the firm owed use tax on out-of-state cards and racks it used in California.
Were monthly charges taxable when an advertising firm owned postcards and racks placed in restaurants for patrons to take free of charge?
No sales tax applied to the advertising-service charges under the ownership assumption, but the firm owed use tax on out-of-state postcards and racks used in California.
Were a private operator's direct food and espresso-cart sales to college students exempt as school meals?
No. The private operator—not the school or student organization—sold directly to students, and the cart's general-purpose room counted as provided eating facilities.
Could a modular-aircraft-kitchen seller claim exemption without proving the kitchens were installed while new aircraft were being completed?
No. The recommendation denied relief because the seller did not document new-aircraft status, installation, or timing. Parts for aircraft already sold or leased into common-carrier use were taxable.
Did buying corporate jewelry-store assets from a Chapter 7 trustee make the buyer successor to an individual's separate tax debt?
No. The trustee sale itself carried no withholding duty, and there was no evidence the buyer purchased the individual's earlier business. California granted the petition rather than impose that…
Could a grocery chain erase use tax on ex-tax fixed assets by later selling and leasing them back, claiming the 90-day acquisition rule or financing treatment?
No. It owed tax on the original purchase and had not proved timely qualifying sale-leasebacks; later rental tax or financing claims did not retroactively cure that liability.
Was a related corporation's marked-up transfer of printed advertising material to its affiliate treated as a sale for California tax purposes?
Yes. Because the price covered the transferor's property cost, allocable overhead, and a markup, California treated the related-party transfer like an arm's-length sale.
Did sending a duplicate source-code copy to a California escrow agent within 90 days make the original software-media purchase taxable?
No. The original media remained and was used in New Hampshire for at least 100 days. Only the duplicate's blank media and copying cost could be taxed on early California entry.
Were vehicle-mounted tracking and messaging units a taxable lease, or incidental equipment supplied with a nontaxable communications service?
The units were incidental to nontaxable tracking and communications services because the provider owned and maintained them, they were useless without its network, and subscribers returned them.
How did a Chapter 11 automatic stay affect California's ten-year period for filing or recording notice of a state tax lien?
After the stay lifted, California had the remaining state-law period or 30 days, whichever was longer; on the facts, the original period had not expired, so no extra federal extension applied.
Did California have authority to release timely filed tax liens solely because staff failed to give the taxpayer the required 30-day advance notice?
No. The memorandum found the notice violation did not make the liens erroneous or supply an independent release ground when the final liability remained enforceable.
Were California sales to an Oregon-chartered credit union exempt like sales to a federal credit union?
No. Federal credit unions were exempt federal instrumentalities, but state-chartered credit unions did not receive that exemption by analogy.
Was a limitations waiver invalid because it omitted the taxpayer's permit number and the auditor filled out the form?
No. The company had only one permit, its controller signed for the named taxpayer, and auditor preparation did not impair the agreement.
When did California use tax become reportable for out-of-state equipment awaiting lengthy installation?
When the equipment entered California. Storage and ownership control were already use, so reporting did not wait for installation and operation.
Were retailer charges for sending and receiving a fax by telephone modem subject to California sales tax?
No. Neither the sending retailer's transmission charge nor the receiving retailer's pickup charge was subject to sales tax.
Did attending California coin conventions only to buy inventory require an out-of-state dealer to collect use tax on later mail sales?
No under the stated historical facts. Buying inventory at one or three conventions did not create the duty, but promoting, displaying, taking orders, or selling coins there would.
Did mailing product-catalog software to California customers create collection responsibility for an out-of-state mail-order retailer?
Not by itself if the diskette merely replaced a paper catalog. But the retailer's California-focused broadcast and publisher advertising already created the duty under the statutes then applied.
Could a seller credit Wisconsin tax on its temporary storage against California tax on later customer sales?
No. Wisconsin taxed the seller's own storage, while California taxed a later sale or the customer's use. Section 6406 did not match different people and transactions.
Were prescription topical creams and ointments exempt from California sales tax?
Yes, under the 1994 opinion, topical creams and ointments qualified as medicines and were exempt when sold or furnished under Regulation 1591(a)'s conditions.
How did California treat intravenous supplies, infusion pumps, and catheters under the medicine exemption?
Most listed supplies were taxable devices. The opinion recognized narrow exemptions for qualifying programmable automatic infusion pumps and for catheters meeting specified implantation, drainage,…
How did California tax advertising on leased compact disks, the disk rentals, and optional telephone information service?
Advertising was nontaxable when advertisers received no tangible property. Modified-CD leases were taxable continuing sales unless a periodical exemption applied, which the facts did not establish.…
How were software licenses and maintenance taxed when master media and the central server were in California but users were worldwide?
California taxed all license fees and tangible updates because the master and server use were in-state. Future remote-only updates were nontaxable.
What changed when an HVAC contractor switched from separately billing fixture-repair parts and labor to one flat repair price?
The contractor became the consumer of the repair parts. Tax applied to its parts purchase, while no sales or use tax applied to the customer's lump-sum repair charge.
When could three hospital emergency-helicopter structures qualify as common carriage, and when was a purported lease really a charter?
Direct patient service and hospital-owned operations could qualify if FAA-authorized and otherwise compliant. An operator serving only one hospital qualified only if it truly transferred possession…
Were ready-to-eat food sales inside an amusement park taxable when patrons used nearby park tables and chairs?
Yes. The nearby eating areas were rationally connected to the park's food stands and counted as retailer facilities, making the food sales taxable.
Were an initial software license fee and per-copy royalties taxable when the buyer only reproduced the program inside products sold to others?
No, if federal copyright attached and the program was transferred solely for copying and sale rather than the buyer's use. Incidental media did not change that result.
Was a testicular gel implant used for replacement after disease exempt medicine in California?
Yes. California said the described replacement implant qualified as medicine under Regulation 1591(b)(2), so its sale was exempt.
Were professional skin-care products exempt whenever they were sold through physicians or aestheticians?
No. California exempted qualifying products sold or furnished by licensed physicians or surgeons during patient treatment, but taxed walk-in, outside-regimen, and ordinary aesthetician sales.
Were nonmedicated wound dressings and packing exempt because they promoted healing and moisture?
No. California treated the products as taxable dressings excluded from medicine under Regulation 1591(c)(2), despite their claimed healing and moisture benefits.
Was Microfoam surgical tape used to hold pressure dressings exempt medicine in California?
No. California treated the described tape as a pressure dressing, which Regulation 1591(c)(2) excluded from medicine as a device, so its sale was taxable.
Were monthly and pay-per-view charges for direct-to-home satellite television signal transmission subject to California sales or use tax?
No. The signal-transmission charges were not sales of tangible property, but California tax still applied to the sale or use of dishes, decoders, remotes, and access cards.
Did a tribe have to register and collect use tax when it manufactured goods on its reservation and sold them to non-Indians or Indians living off reservation?
Yes. On-reservation manufacture did not remove the tribe's duty to register and collect use tax from non-Indians and Indians not residing on a reservation.
Did regular California conference exhibits and occasional order-taking require an out-of-state mail-order seller to collect use tax?
Yes under the historical rule applied. Representatives displayed products and sometimes took orders at California events, so the retailer was engaged in business even before later one-on-one sales calls.
Did the taxable price under a time-and-material construction invoice include fabrication labor and material markup when sales tax was separately itemized?
Yes. The contractor was treated as the retailer, and tax applied to the property's stated price including fabrication and markup, but not installation.
How did California apply sales and use tax to passenger photos, merchandise, supplies, and equipment sold or used aboard a San Diego-to-Ensenada cruise ship?
Inside California's three-mile limit, the onboard retail sales were subject to sales tax. Outside it, sales tax did not apply, but daily California contacts required use-tax collection from known or…
Did extending a tax-paid equipment lease create a new taxable transaction when the original lessee also had a 10% purchase option?
A true extension stayed rent-tax-free; an extension ending in title or a nominal option became a sale at inception taxed when it began.
How were parts and labor taxed when a manufacturer used its subsidiary or independent service centers to perform warranty repairs?
Repair labor was nontaxable. Parts under an optional warranty were consumed by the warrantor; parts under a mandatory warranty were treated as part of the original sale.
Were sales of Capri fig pollen to farmers exempt when the pollen was used to produce edible Calimyrna figs?
Yes. California treated the pollen as an annual plant used to produce food, though the farmer consumed it rather than buying it for resale into the fruit.
Which focus-group coordinator charges were taxable when it supplied sponsors with food, videotapes, facilities, and participant solicitation?
Food, beverages, and videotapes sold to the sponsor were taxable; optional participant solicitation and facility charges were nontaxable under the opinion's service assumptions.
Was a wearable biofeedback speech-therapy system an exempt prosthetic device in California?
No. California said the system administered therapy to develop speech patterns rather than replacing an organ or assisting the larynx's production of speech, so its sales were taxable.
Did California's medical oxygen exemption cover delivery systems and cylinders used in a dentist's office?
No. The personal-use delivery-system exemption required a sale, lease, or rental to an individual for that person's use under physician direction; cylinders remained equipment, although the gases…
Was a medical emergency response card taxable when it represented both an information-transmission membership and prepaid telephone value?
No. The card was incidental to the medical-information service and an indicator of prepaid calling value; the provider was the consumer and owed tax when acquiring the cards.
Was a supplier's sale of a fully worn cervical collar to a chiropractor a taxable retail sale under a 1994 California letter?
Yes, if the item was an orthotic support or brace fully worn by the patient and used or furnished during professional services. The chiropractor was the consumer, so the supplier's sale was taxable…
Would a service-agreement label change the tax treatment if a vendor transferred a computer or digital images?
The label would not control. If the vendor transferred possession of a computer, that would be a lease; if it transferred images on disk or into that computer, that would be a taxable sale.
Could an advertising agency identify nontaxable preliminary art as a creative service fee, and could it qualify when billed after or ordered with finished art?
Yes, if records proved the charge was separately stated preliminary work completed before approval to produce finished art; labels and invoice dates were not controlling.
Were sign-system drawings, sketches, models, and mock-ups taxable design products rather than nontaxable architectural services or preliminary art?
Yes. Clients and fabricators used the delivered designs, so the full contract receipts were taxable; preliminary-art and written-advice defenses failed, though limited credits were allowed.
Was use tax due on a modified van resold before registration when the buyer could not adapt it to her needs?
Use tax remained due because the van accrued over 400 miles during ownership, but the fair market value of qualifying existing accessibility modifications was excluded.
Did selling a used accessible van before registration eliminate the purchaser's California use tax?
No. More than 400 miles during ownership supported California use, so tax remained due despite resale before registration. But the value of qualifying existing accessibility modifications was excluded.
