Did California trade-show employees and itinerant dealers require an out-of-state gun-safe manufacturer to collect use tax on all California retail sales?
Yes under the historical facts. Employees and authorized dealers took California orders, creating nexus for trade-show, dealer, telephone, and mail-order sales.
Were the seller's prefilled saline and Heparin flush syringes exempt from California sales tax?
Potentially, but California gave no final answer. A syringe was taxable as a device unless it was disposable, for one use, and sold prefilled with exempt medicine; the seller had not supplied enough facts.
Was a contractor-group membership exempt when its primary benefit was a mailed weekly construction-bid publication and its only other benefit was bidding-room access?
Likely yes if the publication met every periodical test. The membership was treated as its sale, and bidding-room access was incidental to that exempt subscription.
Was a closely held winery's barrel sale-leaseback merely a bookkeeping or financing transaction exempt from tax?
No. The barrel lessor had a real separate corporate existence and the transaction failed the financing tests, so use tax applied to the winery's rental payments.
Did California's drop-shipment rule make a seller the retailer when it delivered components to a California fabricator working for an out-of-state reseller?
No. The fabricator accepted the components for the out-of-state reseller, assembled them, and shipped them to the reseller's out-of-state customer; delivery was not to an end user or its agent.
Was a startup's stock-purchase warrant part of taxable equipment rent when it was granted alongside periodic lease payments?
Yes if the warrant had determinable commencement value; that value joined periodic rent. A sufficiently speculative warrant was excluded, and a later stock sale was not rent.
Which phases of a medical-center signage project were taxable when the designer provided concepts, preliminary art, finished drawings, and installation review?
Phases I–II were nontaxable preliminary art, Phase III was taxable finished art, and Phase IV had to split nontaxable installation review from taxable production revisions.
Did a party organizer owe tax on the part of its client fee tied to catered meals and other tangible items?
Yes. The tangible-property portion of the organizer's fee was taxable even though subcontractors collected tax; the organizer received credit for tax already paid.
Did a recorded California tax lien remain on real property after the taxpayer quitclaimed it to another person?
Yes. Staff said the transferee had constructive notice and took the property subject to the lien, but the lien did not mean the transferee personally owed the tax.
Were preliminary design concepts taxable when a freelance designer transferred them on paper or computer disk?
Yes for the assumed nonengineering graphic designs. Paper or disk delivery was taxable, and preliminary status or later customer modification did not change the result.
Were CD-ROM mastering fees taxable, and when were customer-owned manufacturing films shipped out of state exempt?
Mastering fees were part of taxable CD-ROM receipts regardless of labeling. Film sales could avoid sales tax only with qualifying out-of-state shipment and delivery.
Could California assess corporate officers under section 6829 while the corporation itself remained in bankruptcy?
Yes, if the officers had not filed personal bankruptcies and section 6829's requirements were met. The corporation's automatic stay did not protect separate nondebtor officers.
Who had to collect California use tax when a Texas retailer bought furniture from a Michigan manufacturer with California offices and drop-shipped it to a California customer?
The manufacturer was deemed the retailer and had to collect use tax on the Texas seller's marked-up retail price, unless the Texas seller registered or was otherwise engaged in California.
When could a purchaser directly claim a California tax refund instead of asking the retailer to file?
Not for sales-tax reimbursement, which only the retailer could reclaim. A purchaser could claim overpaid use tax it actually paid under the stated rules.
Could a qualified nonprofit treated as the consumer add sales tax reimbursement to its fundraising price?
No. Its customer sales were not taxable, and any amount collected as tax was excess reimbursement that had to be refunded to the customer or paid to the Board.
Did selling disposable temperature recorders for refrigerated shipments provide a nontaxable monitoring service or make taxable property sales?
The recorders were taxable tangible property: purchasers could read and use them without the seller, rare calibration work was not the true object, and no agricultural exemption applied.
How did California tax materials and fixtures furnished by non-Indian contractors building homes on reservation land?
Material sales to non-Indian contractors were taxable despite reservation delivery; fixtures they furnished and installed were exempt, with permits limited accordingly.
Could California collect a receiver's unpaid sales tax from an owner's bankruptcy estate after the receiver returned the business assets?
No, on these facts. The court had found the owner not liable, and returning the same assets the estate would have received without the receiver did not enrich the estate; the receiver's bond was the…
Was a commercial artist's full design charge taxable when the artist kept the original and gave the client only a stat copy for a newspaper ad?
Yes. Giving the client a copy of the design was still a taxable transfer of tangible personal property, even though the artist retained the original.
Did a common carrier's generic blanket certificate make a pallet seller's sales exempt?
No. The seller needed a timely certificate substantially matching Regulation 1621 and a qualifying bill of lading; the generic blanket certificate lacked required facts.
Could time using a stolen European car be combined with its replacement to satisfy California's former 90-day vehicle test?
No. The replacement was a different vehicle, and the buyer intended to bring it to California within 90 days, so the historical presumption applied and use tax was due.
Was on-site software reprogramming taxable when the seller's employee used and retained a floppy disk while operating the customer's computer?
No. The employee transferred no title or possession and merely reconditioned programmable equipment rather than fabricating new tangible property.
Were banquet gratuities taxable when the contract called 15% suggested but required customers to agree to some gratuity in advance?
Yes. Because every banquet contract required an advance-negotiated gratuity, the payment was part of taxable gross receipts even though the stated 15% rate was negotiable.
Could a retailer with California sales offices still be located outside the state for section 6487.05's shortened limitation period?
Yes only if its liability was limited to collecting use tax. Any California sales-tax liability from local-office participation would disqualify it.
Could a Texas vehicle-tax amount built into a lease offset California use tax after the lessee moved here?
No. California taxed the lessee's in-state lease payments, while the Texas tax was understood to be imposed on the lessor. The same person had not paid both taxes.
Could a vehicle lessee credit tax economically borne in Texas against California use tax on rents after moving the vehicle to California?
No. California taxed the lease while the vehicle was in the state, and no credit applied because Texas taxed the lessor while California taxed the lessee.
Did a produce-preservation company sell carbon dioxide and lease equipment to customers, or consume those items while providing a nontaxable service?
It provided a service because customer charges were based on produce shipped, not equipment or materials; the company consumed the carbon dioxide, packaging, and equipment it used.
Could a service provider offset excess tax reimbursement against use tax after an audit had instructed it to report its process as taxable sales and leases?
Temporarily. California allowed same-transaction offsets while the Department treated the process as taxable, but none after the provider learned it was a nontaxable service.
Could a produce-preservation service obtain carbon dioxide and its nonreturnable containing materials exempt from California sales and use tax?
Yes, if section 6359.8's conditions were met: the carbon dioxide had to pack and transport fruits or vegetables for human consumption, and the ultimate consumer could not receive the produce in a…
Was the sale of a prepaid telephone debit card a taxable sale of the physical card?
No. The issued card represented prepaid telephone value rather than tangible property, but the issuer was the consumer and tax applied when it acquired the blank card.
Could a subsequent purchaser's vehicle remain a 'new motor vehicle' for Lemon Law purposes while the transferable new-car warranty remained usable?
Yes. California said the vehicle retained that status while the subsequent purchaser could use the express warranty and repair facilities like the original buyer.
Were contraceptives, suction and urinary catheters, and irrigation syringes taxable medical items?
Contraceptive creams, foams, jellies, and suppositories qualified; nonspecific suction catheters and irrigation syringes were taxable, with exceptions for certain catheters.
Was a removable experimental fuel-cell system installed under a federal demonstration contract machinery sold to the government or a taxable fixture?
It was a fixture. Bolting and integration with the plant's steam and electrical systems made the contractor the consumer under a federal construction contract.
Could a print broker use its client's bulk-mail permit, how was camera-ready art taxed, and what happened to excess printed copies?
The client's permit was acceptable if all exemption rules were met; camera-ready art remained taxable, while excess copies were taxed according to disposal, gift, contract, or sale.
Were anti-embolism stockings and external compression systems exempt medicines in California?
The stockings were normally exempt prosthetic devices if they worked separately, but not if they were only machine components. The external pump, sleeve, tubing, and related compression-system parts…
Could an unlicensed business still be a construction contractor for California sales and use tax purposes when it furnished and installed fixtures?
Yes. Contractor licensing did not control the tax classification; the business acted as a construction contractor because it furnished and installed fixtures.
Could a married California taxpayer claim head-of-household status when the taxpayer's spouse was a nonresident alien?
Yes, if the taxpayer personally was not a nonresident alien during any part of the year and otherwise met the head-of-household requirements. A spouse's nonresident-alien status could make the…
Did a licensing agent make taxable artwork sales when it supplied finished art to licensees as part of royalty-based agency services?
Yes. The artwork was not incidental to the licensing services; tax applied to its fair retail selling price, and a proposed five-point commission increase was taxable artwork receipts.
Did broad contract clauses transferring advertising materials and layouts to a client make an agency's preliminary-art charges taxable?
Yes. Read as a whole, the clauses transferred preliminary art to the client, and the agency did not overcome the presumption that its receipts were taxable.
Were physical artwork transfers taxable when an intellectual-property licensing agent supplied designs to licensees without separately charging for them?
Yes. The artwork was a sale rather than merely incidental to licensing services, so tax applied to its fair retail selling price or the extra fee paid for it.
Could a certificate titled 'State Resale Certificate' make dental x-ray film nontaxable when it certified only export and the buyer took California delivery?
No. The certificate did not certify resale, and California delivery defeated export treatment; even a qualifying export required retained proof.
How did California tax alarm equipment, installation, and monitoring under a 36-month furnish-install-monitor contract that retained title until payment?
The installed alarm fixture was a retail sale despite retained title. Its stated or deemed price was taxable, but monitoring and installation charges were excluded.
Did California use tax apply when NASA paid for steel outside California and took title before the contractor fabricated and brought the wind-tunnel parts into the state?
No. Federal title vested outside California before entry, so later installation involved government-owned property rather than contractor use incident to ownership.
Were cellular-equipment sales exempt when a California agency paid 90% with federal transit funds and end users paid the other 10%?
No. Neither the state agency nor end users were the United States, so the entire price was taxable despite federal funding. Required above-market service charges also entered taxable gross receipts.
Was a separately billed performance bond taxable when a fire-truck buyer required the seller to obtain it?
No. Because the seller would sell the truck without the bond and the buyer imposed the requirement, California treated the bond like an optional warranty.
Were rentals taxable when a company bought database diskettes tax-paid and licensed the same disks for a fixed term with mandatory return?
No, if the same-form disks were leased for a fixed term and acquisition tax was paid or timely reported; customer rent was then untaxed.
Could a buyer's later seller's permit validate resale purchases made while its old permit was inactive?
No. A resale certificate required a valid permit at the time, permits could not be backdated, and reimbursement was proper unless actual resale was separately proved.
When did a 1995 California letter treat photograph retouching, restoration, and replacement-print charges as taxable?
The letter taxed retouching a new photograph and the full charge for making a new print. It excluded only labor that repaired and returned the customer's same used, damaged photograph. Its other…
Was the full charge taxable when a photo-restoration business digitally altered a customer's image and sold a newly produced print?
Yes. The letter treated the digitally altered image and finished print as a new taxable print, not repair and return of the same used photograph, so the entire customer charge included the…
How was later delivery of software media taxed after reproduction rights and program data had already transferred electronically?
No tax if the contract required the media at no extra charge; a later additional payment for functional media was taxable, as was other transferred property.
Were nonprofit youth groups selling fundraising merchandise on their own account or as the supplier's agents?
They were the supplier's agents because the supplier failed the own-account presumption; the supplier was the retailer and tax was measured by ultimate-customer payments.
Were accepted packaging-design concepts taxable property or nontaxable design services and preliminary art?
They were taxable at the full amount received because clients obtained title and used the physical designs; the preliminary-art exclusion also failed because title passed and charges were not separate.
Could a uniform manufacturer avoid tax on rents by moving finished uniforms to a rental division or selling them to a related rental subsidiary?
A same-company division could not; rents were taxable. A separate subsidiary could elect tax on cost only if the related sale was genuine and priced to include all costs and overhead.
Were packaging shapes and graphic surfaces taxable when clients received exclusive ownership of accepted design concepts without a separate preliminary-art charge?
Yes. Clients bought tangible packaging concepts for their own use, title passed, and no preliminary-art charge was separately stated; the negligence penalty was waived.
Which mandatory charges for installing prewritten software and converting customer data were taxable?
Actual installation and operational testing were excluded. Required data conversion was not installation and remained part of the taxable software sale.
Could preliminary art remain nontaxable if the client was allowed to dispose of the roughs after review instead of returning them to the agency?
No. The agency had to retrieve preliminary art after client review; allowing the client to dispose of it meant the agency sold it and tax applied.
How did California tax parts used in medical-equipment repairs performed out of state and shipped back to California hospitals?
Retailer treatment depended on separately stated charges or the parts' share of the repair price. The repairer had California nexus and had to collect applicable use tax.
Did taking custom-knife orders at one California show create use-tax collection responsibility even when every knife shipped later from Montana?
Yes under the historical rule applied. Entering California once to solicit or take orders was enough, even if no property changed hands at the show and every knife shipped later.
Did a District of Columbia exemption certificate exempt California marine-fuel sales to the Argentine Navy?
No. The California sales were taxable because no qualifying U.S. Department of State Tax Exemption Card or other California exemption proof was provided.
Did an annual association directory qualify as a periodical or printed sales message, and how were member copies, reliance on a prior audit, and interest treated?
It was not a periodical, but most copies qualified as printed sales messages; 275 member copies were taxable, written-advice relief failed, and interest remained due.
