Was a wheel-balancing business the consumer or retailer of wheel weights furnished during balancing?
It was the consumer when wheel weights were worth less than ten percent of the total charge and were not separately charged.
When did the limitations period begin for a California sales-tax bad-debt claim?
The final memorandum used the period of the book entry claiming the debt, not an earlier time when the account was first found worthless.
Were separately billed custom seismic calculations taxable when the seller prepared them as a condition of selling industrial valves to a California customer?
Yes. The engineering service was part of the taxable valve sale, so the seismic-calculation charge entered the seller's gross receipts.
Were separately charged payment coupon books taxable when supplied as part of an accounts-receivable service?
No. The letter treated the customer-specific coupons as advance monthly invoices within a billing service, not taxable property sold by the service bureau.
Did distributing photoprocessing mailers and using a California post-office box to forward orders require the out-of-state company to collect use tax?
Yes under the historical analysis. Someone gathered customer mail from the California box and forwarded it to Pennsylvania, supplying an in-state representative for taking orders.
Could a film provider treat projectors and accessories in one customer package as free accommodations rather than taxable equipment rentals?
No. Required equipment representing about 77% of unit investment produced taxable apportioned rent, but the negligence penalty was deleted.
Did using California television-station box numbers to receive and forward orders require an out-of-state advertiser to collect use tax?
Yes under the historical analysis. Contracting with local stations to forward mailed orders made the stations the retailer's California agents and extended collection to all California sales.
Was an apparel manufacturer's use of ex-tax yardage to make style samples taxable when the garments were shown to buyers and later sold?
No. The manufacturer incorporated the yardage into sample garments, used those garments solely to obtain buyer orders through demonstration or display, and held them for eventual sale in its retail…
Did sending property to a California buyer on approval automatically subject the out-of-state seller to California sales tax?
No. The Board treated a contract to sell on approval as a contract of sale for Regulation 1620(a)(2)(B). If that regulation's conditions were met and the required California nexus was absent, sales…
Did a buyer-hired skipper qualify as a carrier when sailing a purchased yacht from California to Oregon?
Yes. The skipper regularly delivered other owners' vessels for fixed fees, so he was a contract carrier even though no Coast Guard, PUC, or ICC license created that status. Delivery to him under the…
Did paying the amount a buyer believed was the seller's full tax debt protect against later California successor liability?
No. Paying $877 based on an alleged oral account inquiry did not replace the statutory receipt or no-amount-due certificate. The buyer remained liable up to the price paid for his half-interest when…
Did a doctor's record-access charge enter a photocopy service's taxable sales price when the service passed it through to the customer without markup?
Yes. The access charge was an expense of filling the copy order and remained taxable gross receipts even when passed through at cost.
Could California tax cigarettes and spirits withdrawn from bond for a foreign naval vessel but consumed locally?
California could not impose sales or cigarette tax on these bonded foreign-warship sales, the memo concluded. It could impose alcohol excise tax on spirits consumed in California; documented export…
Did a lessee's later installation of rear seats change the tax treatment of a van leased with only a front seat?
No. California classified the front-seat-only van as MTE when leased, making the dealer's sale to the lessor taxable; later rear seats did not change that original transaction.
Could a body shop treat consumable repair supplies as resale items and charge customers sales-tax reimbursement on a flat supply fee?
No. Supplies such as thinner, abrasives, and masking tape were consumed by the shop; it owed tax on them and could not charge customers tax reimbursement.
Were truck cranes with 10-to-25-ton lifting capacity mobile transportation equipment?
Yes. Their greater road speed and range, lack of special-permit requirements, and carriage of the driver and crane itself supported MTE classification.
How were photographs, artwork, and typography treated when an advertising agency's employees incorporated them into finished mechanical art?
The agency was the retailer of employee-produced finished art and was not the client's agent for physically incorporated materials; tax-paid cost credit could apply to those components, while…
Did title passing in California turn a direct interstate sale-on-approval shipment into a California sales-tax transaction?
No. Board counsel viewed the transaction as subject to use tax under Regulation 1620(a)(2)(B), not sales tax, when the California buyer ordered directly from an out-of-state retailer and the goods…
Did a banquet tip become a taxable service charge merely because the customer asked the restaurant to include the customer-selected amount in a tax-and-tip price?
No. The customer chose the amount voluntarily, the restaurant distributed it to employees, and the recommendation deleted tax from those tips.
Does a seller's internal pricing calculation make the customer price tax-included when the order form says nothing about tax?
No. Internal costing was irrelevant; the seller had to clearly notify each customer that part of the charge represented tax or tax reimbursement.
How could a shipper prove it sold packing materials to its customer before using them?
The independent shipper needed every Regulation 1630(b)(2) condition: an express customer contract and separate charge, title passage before any packing use, and no understanding or trade custom of…
Could a store discount selected merchandise by the tax rate and treat the resulting advertised price as tax-included?
Yes, with clear pre-sale notice of both the discount and tax-included price. A later receipt-based bonus was a patronage dividend and did not reduce gross receipts.
How did California classify food-service items as materials, fixtures, or machinery and equipment?
Integrated items losing identity were materials, attached accessories were fixtures, and freestanding readily removable restaurant equipment remained machinery and equipment.
How did California tax custom conveyor systems, supports, and design charges?
The conveyor systems were fixtures; attached supports, catwalks, and platforms were materials. The fixture measure included standard or special-unit pricing and equipment-design work, but excluded…
Was a mobilehome broker liable for tax on the home and its unattached accessories?
A true broker was liable for the mobilehome sale, not automatically for separate awnings or furnishings; a broker empowered to pass title was retailer of all items.
Were retail sales and resales of secondhand comic books exempt when the comics qualified as exempt periodicals when first issued?
Yes, unless sold as scrap. Comic books exempt as periodicals when issued remained exempt on later retail sales and resales.
Did tax apply to bonded fuel loaded at a California stop when the flight began abroad and then continued to an out-of-state destination?
No, the modified advice said. An aircraft stayed in foreign commerce when its origin or destination was abroad despite multiple U.S. stops.
Which exchange rate determined California gross receipts when a retailer accepted foreign currency that later changed value?
The exchange rate at the time of sale controlled. A later gain or loss while the retailer held the currency did not change the sale's U.S.-dollar measure.
Was crushing stockpiled concrete and asphalt for road reuse taxable processing?
Yes. Once removed and stockpiled, the roadbed chunks were tangible personal property, and crushing them for the owner's reuse was a taxable processing sale even though nothing was added.
Did shareholders' self-help division of corporate equipment create a purchase supporting California successor liability?
Not on the available evidence. Without an agreed exchange for consideration, there was no purchase price and no established successor liability. The corporate assets could still be recovered, levied…
Were charges for printed lists of available rental properties subject to California sales tax?
Yes. Selling rental-property lists was taxable tangible-property sales unless the seller qualified as an advance-fee rental agent.
Did customer purchase orders mentioning tooling override a plastic-parts manufacturer's quotation saying it retained title and possession?
Generally no on the four records reviewed. Tooling ownership depended on the parts contract, and conflicting form terms often dropped out under UCC section 2207.
Did a quick-disconnect swimming-pool cleaning unit qualify as a fixture?
Yes. Easy removal did not defeat fixture status because the head and hoses were adapted to the pool, essential to the installed cleaning system, and intended to remain until worn out or replaced.
Did California sales tax apply to sales of human body parts for medical use?
No. The source states that sales tax did not apply to sales of human body parts for medical usage.
Did an invoice have to use the exact words 'preliminary art' to satisfy Regulation 1540's clear-identification requirement?
No. Descriptive invoice terms such as roughs, visualizations, layouts, comprehensives, or concept art could satisfy the identification standard without using the exact label 'preliminary art.'
How were mailing-list addressing, update proofs, labels, and computer tapes taxed?
Addressing, mailing labels, and a single returned update proof were nontaxable. Mailing-list tapes furnished to clients were taxable unless supported by resale certificates.
Were the RIA-Mat Angiotensin II 125 and Res-O-Mat T3I 125 laboratory kits exempt medicines?
No. California corrected its earlier advice because testing a specimen outside the patient was not internal or external application to the human body.
Could an equipment lessor convert ex-tax rental inventory to tax-paid status by a planned fair-market-value sale and reacquisition?
No for the proposed plan. Staff said it would not avoid tax on rent: a prearranged reacquisition would be a sham late election, and the claimed market value could not be satisfactorily verified.
Was a dispensing optician the consumer or retailer of eyeglasses supplied directly to wearers versus to physicians or optometrists?
The optician was the consumer when dispensing directly to wearers, but the retailer when transferring eyeglasses to physicians or optometrists for their patients.
When was an electric-clock repairer the retailer rather than the consumer of replacement parts?
When parts exceeded ten percent of the total repair charge or were separately charged; electric-clock repairs followed the ordinary repair rule.
Did a nonprofit tackle-football league qualify for section 6361 treatment when it excluded girls?
No. Section 6361's statutory-consumer treatment was limited to qualifying youth organizations that did not discriminate based on sex, so the league's sales were taxable retail sales.
Could a mobile-home buyer avoid successor liability by labeling its agreement an asset purchase rather than a business purchase?
No. The buyer acquired inventory and operating assets, continued at the location, and paid by assuming liabilities. The contract label and exclusion of the name, receivables, warranties, goodwill,…
Did manuscript data encoded on computer tape qualify as nontaxable composed type?
No. California treated machine-readable tapes and cards as production aids, not human-readable composed type, and recommended leaving the use-tax assessment unchanged.
Could identically owned manufacturing and leasing partnerships treat houseboat transfers between them as tax-paid purchases?
No under historical aggregate theory. Identical partnerships were one tax person; manufacturer-lessor owed rent tax, and both petitions got no adjustment.
Was a permanently implanted artificial sphincter exempt when used to normalize bowel movements after paralysis?
Yes. California treated the permanent implant as exempt medicine under the historical implanted-article provision.
Did small radioactive pellets used temporarily under the skin for cancer treatment remain exempt when leased?
Yes under the described direct-to-patient lease. California treated the physician-administered pellets as medicine despite short implantation and reuse.
Could a glass-container manufacturer buy gypsum for resale when it aided melting but supplied calcium oxide essential to durable glass?
Yes. A substantial portion became essential calcium oxide in the glass, so gypsum qualified for resale despite also aiding manufacture and partly dissipating.
Were hospital pill containers treated differently for outpatient prescriptions and inpatient ward use?
Yes. Outpatient containers transferred with exempt medicine were exempt, while inpatient containers were first used by the hospital and could not support a resale deduction.
Did a restaurant make taxable meal sales when confidential shoppers paid normally, reported on quality, and were later reimbursed?
Yes. The shoppers bought meals for the ordinary customer price; their later reports and reimbursements did not make the restaurant the consumer.
How did California treat a caterer's receipts from a federally funded school lunch program, financial-aid meal tickets, and free employer meals?
Treatment depended on who owed for the meal. School-only federal-program payments could be resale receipts; aid tickets depended on the school's meal obligation; and catered meals given free by an…
Were equipment sales to a medical peer-review organization exempt because federal funds supported its Medicare and Medicaid review work?
No. California said the organization had no sales or use tax exemption of its own, so equipment bought for its use was sold at retail and taxable despite the federal funding.
How did subcontracting door detailing, machining, and installation affect the taxable transactions?
The prime consumed installed doors; separately subcontracted machining was taxable processing, and detailing was taxable only when part of that machining sale.
Was a list owner's transfer of magnetic tape to a mailing company a lease when the company copied the tape and returned it?
Yes. Making two copies exercised dominion and control over the owner's tape, and the company acted as an independent contractor rather than an employee.
Could machinery-seller charges for training a customer's staff be excluded from taxable gross receipts?
Yes, when training was separately identifiable and optional; practically or contractually mandatory training remained part of taxable equipment receipts.
Could a machinery seller exclude separately stated charges for training the customer's staff from California taxable gross receipts?
Only when the training was separately identifiable and optional. Practically or contractually mandatory training remained part of taxable equipment receipts.
Did a soft drink and sandwich sold together constitute a meal after the Hart's Drive-In decision?
Yes. Tax counsel treated meal status as a factual question and concluded that modern eating habits supported classifying the combination as a meal.
Were failure-analysis reports taxable when they included photomicrographs or encased component cross-sections, and what if the contractor only prepared a section?
Reports with unpriced illustrations were nontaxable services, but splitting and encasing a customer component without analysis was taxable fabrication.
Were transformers, switchgear, conduit, and cable installed in federal-base electrical distribution systems machinery and equipment or real-property improvements?
They were real-property improvements. The contractor consumed the ex-tax components and owed use tax, except that genuinely temporary equipment could fall outside the system.
Did the publications “Bestline Treasures” and “Keys to Success” qualify for California's newspaper and periodical exemption?
No. Neither publication qualified, but the memo gives only a comparison to absent Crown and Corporate Calendar materials.
Did a newsletter sent every four to six weeks qualify as an exempt periodical when it lacked a stated, regular publication schedule?
No on its current schedule. Four-to-six-week issuance was not a stated, regular interval; a regular schedule would qualify.
