Were automobile-lease due-date change, assumption, and optional GAP-waiver charges included in taxable rental receipts?
Due-date change and assumption fees were taxable lease payments, but the later, optional, separately stated GAP-waiver charge was not taxable rent.
Did California use tax apply to an Oregon-bought motorhome and tow trailer briefly brought home before five months of out-of-state travel?
It depended on first use. Empty delivery for packing meant California first use and tax; actual out-of-state towing plus five months away could avoid tax.
Why were sales of Crystal Geyser Sparkling Mineral Water taxable while noncarbonated Kern's Nectar qualified as an exempt food product?
Crystal Geyser was taxable because it was carbonated. Noncarbonated Kern's Nectar qualified as a food product because it contained fruit juice.
Did using a California toll-free answering service to take orders make an out-of-state retailer collect use tax?
Yes under the historical rule applied. The California service was the retailer's order-taking representative; a 1997 source note extended collection to all taxable California sales, not just…
Did a commonly owned California marketing subsidiary make a separate out-of-state catalog company collect use tax?
The 1978 letter said no on facts showing separate people, products, budgets, and operations. Later 1989 and 1997 notes changed—and then withdrew—the section 6203(f) qualification.
How did California tax a single-price post-warranty agreement covering hardware service, software updates, and technical support?
The charge had to be allocated: actual hardware maintenance was nontaxable, while prewritten software updates on tangible media and mandatory support tied to them were taxable.
Did ordinary IV sets and laboratory reagents qualify as exempt prescription medicines, and could the refund claims proceed as a class?
No on the presented record. IV sets were taxable devices, reagents were applied to removed specimens rather than the body, and the proposed class and individual claims failed.
Did a sale of all LLC assets to a related new subsidiary qualify as an occasional sale when ultimate ownership matched through multiple entity levels?
Yes for the proposed transaction under counsel's assumptions. Parent-child tracing left A, B, and C with one-third ultimate interests before and after Newco's all-assets purchase, so counsel…
Could a rental agency lease replacement cars to a dealer for resale when the dealer supplied loaners during warranty repairs?
Sometimes. Required taxed-warranty and continuing-lease loaners were resale; accommodation or tax-paid-lease loaners were dealer use.
After a $1-title-transfer freezer contract defaulted, could the seller reverse the original tax and tax only the replacement contract?
No automatic reversal. The first and replacement $1-transfer contracts were separate sales; refund/credit or bad-debt relief required proof.
How was a freezer 'lease' with a $1 ownership transfer taxed after default, repossession, and resale?
Each $1-option contract was a sale at inception taxed on its full contract price; repossession could support bad-debt relief but not an automatic refund.
Which catalogs, conference materials, contest and seminar flyers, informational publications, and fundraising newsletters qualified as printed sales messages?
Materials promoting paid lessons or conferences qualified; a free contest, scholarship-supported seminar, mostly informational publication, and fundraising newsletter did not.
Was software installed from the seller's CD directly into a customer's computer nontaxable when the seller removed its media afterward?
Yes for direct installation into permanent computer memory with no seller property left behind; writing the program onto a customer-owned disk, tape, or CD was taxable fabrication.
Were an online classified-advertising company's listing and success fees taxable, and did it have to collect tax on sales completed directly by its users?
No. The online operation was a nontaxable service, and the company did not owe or collect tax on user sales because it never held the goods, accepted bids, transferred title, or acted as auctioneer…
Did a no-asset Chapter 7 discharge eliminate a California sales-tax determination that remained under a timely petition for redetermination?
No. Staff concluded the petition kept the liability from becoming due, payable, final, or assessed, and the later Chapter 7 discharge did not eliminate it.
Did ramp fire extinguishers and equipment used to load or unload aircraft passengers and cargo qualify as exempt aircraft component parts?
No. They were not attached to the aircraft and served ground loading, unloading, maintenance, or repair functions, so none of the described equipment qualified for the component-part exemption.
Did routing foreign custom furniture through an independent warehouse-carrier make the freight taxable before final home delivery?
No. The warehouse was a necessary incident of continuous carriage, not storage for the retailer or buyer, so the separately stated actual common-carrier freight stayed exempt.
Were $100-per-day classroom computer sessions taxable rentals when customers supplied their own software and instructors?
Yes. Customers paid to use the computers, no acquisition tax was assumed, and $100 exceeded the under-$20, under-one-day premises exception.
Was a publisher's charge taxable when it solely licensed another person the right to reprint information from its publications?
No. A charge solely for the right to reprint information was not taxable; the conclusion was limited to the licensing right and did not cover a transfer of tangible copies or other property.
Was an insurance company's California purchase of labels taxable when title passed to it outside the state?
No, on the stated assumptions. Out-of-state carrier delivery made use tax, rather than retailer sales tax, applicable, and the insurer's California use was exempt.
Could a modular-building lessor buy refurbishment materials for resale or deduct tax mistakenly paid on components?
Yes for material bought to become a component of buildings in taxable continuing leases; property merely used in refurbishment stayed taxable.
Did a cancer-services nonprofit's thrift stores qualify for the historical section 6363.3 exemption?
No. The statute's defined qualifying illness was HIV disease or AIDS, so services for cancer patients did not meet that specific nonprofit definition.
Were custom embroidery designs delivered on punched paper tape or diskette taxable as computer programs?
No, when prepared to a customer's special order. The machine-readable designs were exempt custom computer programming, regardless of their delivery form.
Who reported sales tax when a window subcontractor separately billed the prime contractor for materials, labor, and tax?
The subcontractor. Its time-and-material invoices and tax charge created a presumption that it retailed the window materials to the prime contractor.
Did taking a corporation's operating assets in satisfaction of the stock buyers' debt create successor liability despite being labeled repossession or foreclosure?
Yes. The former owners' trust received corporate property for consideration, transferred it to people who continued the business, and thereby completed a purchase. California rejected the claimed…
Could a bank apply a taxpayer's deposit-account funds to its loan after a California tax levy triggered default under an earlier security agreement?
Yes. Staff said the bank's earlier perfected security interest let it apply all account funds to the loan, and sales tax reimbursement in the account had no special priority.
Was a $250,000 settlement over alleged unauthorized use of licensed software subject to California sales tax?
Yes. The payment settled amounts attributed to acquiring taxable software and its license rights, so it was taxable gross receipts from the software sale.
Could a seller exclude any part of a standard shipping-and-handling charge without records of actual postage for each order?
No. Without transaction-level transportation records, California taxed the entire combined charge; aggregate cost recovery could not establish an exempt postage amount.
Did an out-of-state catalog retailer create California use-tax collection nexus by conducting photo shoots in the state?
Taking catalog photos was not a selling activity, but using an exclusive California work or photo site could create nexus as a place of business.
Did California's food-container regulation amendment end the exemption for nonreturnable containers sold to commercial packers?
No. Assistant Chief Counsel said the Board did not intend its Regulation 1589 food-container amendment to reverse the long-standing section 6364 treatment for empty nonreturnable containers sold to…
Could commercial packers buy nonreturnable containers tax-free when filling them with customers' products for resale?
Yes. California's section 6364 interpretation exempted those container sales, and the Regulation 1589 amendment was not intended to narrow that treatment.
Did an LLC seller's-permit application need detailed identification for a nonmanaging foreign-corporate member or California registration for that corporation?
No, under the 1997 memorandum. The LLC had to give detailed information for managing members, not this nonmanaging corporate member, and a valid foreign corporation did not need California…
Were sales of the PROTONICS hinged knee brace exempt as prescription medicine?
Only under specified conditions. California treated the fully worn hinged knee brace as an orthotic device, but patient sales required a written order from a licensed physician or podiatrist.
Were custom-furniture freight charges exempt when one common carrier handed the shipment to a local carrier for final delivery?
It depended on the consignee. Shipment to the buyer care of the local carrier remained direct and exempt; shipment to the retailer made the first leg taxable incoming freight.
Was a slide-in camper exempt because its Canadian purchasers took it home after the California retailer installed it on their truck?
No. The retailer did not ship the camper outside California, and a slide-in camper was not a new motor vehicle eligible for the foreign-resident exemption.
Did California need a nominee lien after a deceased taxpayer's property was transferred following the recording of two existing state tax liens?
No. Staff said the two existing tax liens had already attached before the property transfer, so recording an additional nominee lien was unnecessary.
Was selling internet advertising space subject to California sales or use tax?
No when the advertiser received no tangible personal property. If the advertising-space seller also provided tangible property, the charges for that property were taxable.
Were charges for collecting, electronically transmitting, and reconciling patient payments taxable when the processor also supplied periodic reports?
No. The true object was account-collection and reconciliation services, so customer charges were not taxable; the processor was the consumer of report materials and owed tax when buying or using…
Were CAD design charges for PCB photoplot tooling taxable, and did an older published annotation protect the manufacturer for the audited periods?
Current regulation made the full tooling contract, including design, taxable even if separately stated. Appeals recommended deleting audited NRSU charges because older published advice said…
Were noncarbonated sports drinks such as Gatorade, Powerburst, and Exceed exempt from California sales tax as food products?
Yes. Tax counsel said the named noncarbonated sports drinks qualified as food products whose sales were exempt under Regulation 1602(a)(1).
Were sales of permanently implanted Biogran bone-graft material taxable?
No. California concluded that Biogran stimulated the body's natural bone-growth function and was permanently implanted, so its sales were not subject to tax.
Were over-the-counter sales of Zbar exempt as sales of food?
No. California treated Zbar as a medicine designed to regulate blood sugar rather than an exempt food product, and its over-the-counter sales did not meet the medicine-exemption conditions.
Which items in an autobody shop's miscellaneous-materials charge were taxable sales to customers rather than supplies consumed by the shop?
Installed lubricants, adhesives, nuts, and bolts were sold to customers; rags, abrasives, cleaners, masking materials, and similar shop supplies were consumed.
Did a reseller make a taxable use of a software disk by remotely transmitting its contents instead of reselling the disk?
Yes. Because the disk itself was not resold, transmitting its contents was a taxable use, measured by the reseller's cost of the program.
Were refrigerators exempt when sold through different delivery chains but installed in galleys as part of completing new common-carrier aircraft?
Yes, in all three scenarios, if installation was part of manufacturing or completing a new aircraft whose purchase otherwise qualified under section 6366. Installation after common-carrier use began…
When did section 6353 exempt propane placed in a tank at the customer's location and later delivered to the premises as vapor?
Only when the seller controlled the tank and expressly retained title and possession until the propane reached the customer's premises in vapor form through mains or pipes. Customer control…
When was hay sold for horse feed taxable, exempt as feed, or nontaxable as a resale?
Hay for pet or work horses was taxable. Hay for horses held solely for sale was feed-exempt, and hay bought solely for resale was nontaxable, with timely certificates advised.
When did a retailer overpay tax after mistakenly charging reimbursement on a resale and later refunding the customer?
In the quarter when the retailer reported and remitted the erroneous sales tax, not the later quarter when it refunded the customer.
Was a doctor-recommended hot tub exempt as prescription medicine?
No. California held that a hot tub was neither a listed exempt item nor a qualifying orthotic or prosthetic device, so the sale remained taxable despite the doctor's recommendation.
Could California use the eight-year limitations period against an unregistered co-owner after the registered joint venturer filed a vehicle registration return?
No, absent a fraud finding. The unregistered co-owner received the benefit of the joint venture's filed return, so the same expired three-year period applied.
Could a business still use the nondealer vessel-sale exemption after evolving from boat repair into building and selling racing boats?
No. Its business had become selling racing boats, so it was required to remit sales tax and could not rely on purchasers paying use tax at DMV.
Could a vehicle lessor avoid filing its own California return because a retail partner collected and reported the rental tax?
No. Assuming the client was lessor, it needed a separate return; the retailer could prepare/sign that return only as authorized agent.
Could a vehicle lessor report its rentals and use tax on another retailer's return instead of filing its own return?
No. The lessor had to file a separate return reporting its rentals and tax, although the retailer could prepare and sign that return as the lessor's authorized agent.
Could California use the eight-year no-return period against an unregistered co-owner when the other joint venturer had registered the vehicle with DMV?
No, absent a fraud finding. Staff treated the DMV registration as the joint venture's return, so both owners received the three-year limitation period, which had expired.
Were an advertising agency's charges for finished artwork delivered only by modem subject to California sales tax?
No, if no physical form was transferred. The agency still needed evidence of modem delivery, and tax continued to apply to supplies bought by it or its client.
Was finished artwork sent by modem subject to California sales tax, and what evidence should the advertising agency retain?
No, if no physical artwork was transferred. The agency still needed evidence such as a receipt acknowledgment, an invoice notation, and a dated hard copy.
What information did a water carrier have to provide for a seller to accept Certificate E on an exempt marine-fuel sale?
The carrier had to complete all material Certificate E information, including fuel-on-board and voyage-use details; an incomplete certificate did not support the exemption.
Did assigning an existing tax-paid equipment lease to a new subsidiary make the remaining rental payments taxable?
No, if the property was transferred solely for first-issue stock. The existing lease kept its tax-paid treatment, but a renewal or new lease was generally taxable.
Did a 1997 opinion treat duplicating 500 to 600 electronic press-kit tapes from a completed studio master as qualified production services?
No. It excluded the copies from qualified production services, but California expressly disapproved that conclusion in Annotation 375.0057 in 2004.
Was labor to replace a motherboard or add memory to a customer's used computer taxable?
No, when it merely upgraded the customer's used computer without refitting it for a different use. The parts were taxable; a later computer sale differed.
