Could California require the University of Minnesota Press to register as an in-state retailer and collect use tax from California customers?

No under the 1967 memorandum. A federal decision treated the University Regents' acts as Minnesota's acts and the Press as a state agency. California's stated administrative position excluded sister…

1967-05-18

Was a completed mosaic mural bolted to a wall a fixture or material?

It was a fixture because the finished framed artwork retained its identity after bolted attachment. A mural created tile by tile directly on the wall would instead be materials consumed by the artist.

1967-05-17

Did a monthly subscription newsletter containing information for stock-market investors qualify as an exempt publication?

Yes under the historical ruling. Counsel treated the proposed monthly subscription newsletter as an exempt publication after reviewing an absent exhibit.

1967-05-16

Did a textbook publisher owe use tax on examination copies shown before a school sale and retained afterward as desk copies?

No, under the described transactions. Before the textbook sale, examination copies were held for demonstration and display. After the sale, those copies and additional desk copies were treated as a…

1967-05-11

Was varityped copy nontaxable as a reproduction proof when it was physically incorporated into a paste-up sold for producing printed matter?

No. Standalone varityped copy used exclusively as a reproduction proof was treated as a service, but once incorporated into a sold paste-up, the entire paste-up charge—including the copy portion—was…

1967-05-11

When were equipment and materials bought under a federal cost-reimbursement contract exempt sales for resale to the United States?

Direct-cost property qualified when an appropriate clause passed title before contractor use, the government reimbursed actual cost and controlled the property, and it was not used for real-property…

1967-05-08

Was a non-self-propelled houseboat subject to use tax as a vessel?

Yes. A house built on a boat hull remained a vessel even if it moved only by tow, and the purchaser owed use tax on the sale.

1967-04-27

Did newspaper publication of a bulk-sale notice give the Board effective notice of partnership dissolution and end later sales-tax liability?

No. The April 26 letter treated newspaper publication of a bulk-sale notice as ineffective to end post-dissolution tax liability; the Board required actual notice, which an auditor received July 14,…

1967-04-26

Did selling 43 percent of a sole proprietorship's property to a new wholly owned corporation and leasing the remaining 57 percent transfer substantially all property?

No under this advice. Section 6006.5(b)'s `transfer` meant conveyance of beneficial ownership. A true lease passed possession but left beneficial ownership with the proprietor, so the 57-percent…

1967-04-24

Were office-supply sales solicited through independent jobbers taxable to the jobbers or to the corporation whose contracts controlled the transactions?

They were taxable to the corporation. It controlled order acceptance, billing, title, receivables, customer payments, and jobber compensation, so the jobbers solicited as its agents rather than…

1967-04-19

Could separate body and chassis sales remain exempt when the body was installed here and the chassis builder shipped the completed vehicle outside California?

Yes, under the proposal, if both orders required outside delivery, a real agency relationship covered the body's shipment and records identified each vehicle.

1967-04-17

Was an organization a consumer or retailer when it furnished publications as part of a lump-sum membership, and were its mailing containers taxable?

Tentatively, it was the consumer when publication was incidental to membership, making its mailing-container purchases taxable.

1967-04-07

Could a later contract amendment retroactively move title passage outside California?

Not for property already delivered before the amendment; California's tax right had vested. The amendment could affect later undelivered equipment, including qualifying separately stated transportation.

1967-03-29

Were transfers between the University of California and another California state agency taxable sales, and was the transferor's original purchase for resale?

Interagency transfers were not sales because UC was part of the state, but the transferor agency's original purchase was taxable because it was not buying for resale.

1967-03-13

Was a photographer's charge taxable for photographing a newspaper page paste-up used to make a printing plate?

Yes. California treated the photographer as selling tangible personal property at retail to the newspaper and taxed the charge.

1967-03-08

Were leased credit-reference books exempt periodicals when revised every two months, and what happened to a similar book revised only twice a year?

The bimonthly books qualified under the 1967 analysis; the twice-yearly manufacturers' book failed and its rentals were taxable.

1967-03-07

Could a retailer deduct bad debts after assigning its receivables?

Yes, when the assignment left the retailer bearing the bad-debt loss from its own sales, as though it had retained the receivables.

1967-03-03

Were annual and biannual freight guides periodicals, and how did California treat monthly update supplements?

Annual guides and a biannual supplement were not periodicals; monthly updates could qualify if they met the advertising limit.

1967-03-02

Were printed forms and copies transferred between two closely connected corporations taxable when one billed the other for their cost?

Yes. Their close relationship and expense reimbursements did not erase their status as separate entities or the billed retail sales.

1967-02-24

Did bound Oceanic Abstracts volumes offered at irregular intervals qualify as exempt periodicals?

No. California treated the irregularly offered bound abstracts as taxable retail publications, while allowing resale treatment for printing and physical components.

1967-02-17

Did the bimonthly Oceanic Index, which accumulated marine-literature references during the year, qualify as an exempt periodical?

Yes. California exempted its $300 annual subscription and printing because the marine-literature index appeared every two months.

1967-02-17

Could a caterer exclude separately stated amounts paid to temporary servers, bartenders, and dishwashers from taxable gross receipts?

No. When the caterer solicited, engaged, or hired the temporary help, tax counsel treated the workers' charges as part of the food sale even if separately stated or paid through another arrangement.

1967-02-15

Could a caterer exclude separately billed wages for temporary workers who served food, tended bar, and washed dishes?

No. Because the caterer arranged the help and the services formed part of selling the food, the customer-paid wages remained in gross receipts.

1967-02-15

Could a candy maker buy Ketlube for resale when it lubricated cooking kettles but was mostly absorbed into the candy?

Yes. About 98% entered the candy and gave it a texture that improved shaping, cutting, and wrapping, so it was a resold ingredient rather than only a lubricant.

1967-02-10

Were bowling score sheets exempt periodicals, and how did tax apply to printer deliveries, the client's use, and the negligence penalty?

No. The sheets failed content and interval tests; California delivery and client use were taxable, but counsel recommended removing the negligence penalty.

1967-02-08

Was a partnership's California yacht sale occasional when the partners called it personal but their books carried its expenses and depreciation?

No under staff's historical analysis. The books supported business-asset treatment, and three other substantial sales formed a permit-requiring series. The live annotation warns that vessel law…

1967-02-02

Did regularly bringing goods into California and handing them to customers or another carrier require an out-of-state seller to collect use tax?

Yes under the historical analysis. Employees and vehicles regularly participating in California customer deliveries supplied nexus, including transfer to another carrier for final delivery.

1967-01-19

Were computerized federal and state tax-return preparation charges taxable when the provider evaluated customer facts and calculated deductions, credits, and recapture?

No. The provider performed tax-preparation services and consumed three return copies, but separately supplied forms, worksheets, and magnetic tape remained taxable.

1967-01-17

Were purchases by San Francisco's Economic Opportunity Council exempt because invoices said nonprofit, government, or federal grant?

No. California said the local council was not a United States instrumentality or federally owned corporation. Federal grant funding and nonprofit status did not create a sales tax exemption.

1966-12-29

Could a dealer add normal reconditioning costs to the bad-debt credit for repossessed cars?

No for average-condition cars because the guide value already reflected normal preparation; an adjustment was possible for cars outside average condition.

1966-12-09

Was a used-car dealer the retailer or consumer of parts furnished under a manufacturer's optional power-train warranty?

The dealer was the retailer. Tax applied to its separately stated parts charge to the manufacturer, including the parts markup; the remitted warranty premium was not dealer gross receipts.

1966-11-30

Were charges for cutting, sizing, styling, and coloring new wigs excluded as installation or service labor?

No. The charges were part of the taxable price of new wigs; the cited installation exclusion covered emplacement, not styling. Restyling used wigs was treated differently.

1966-11-30

Could parties label installed property personal property and override contractor tax classification?

No. Physical attachment and the contractor-rule definitions controlled whether installed property was material or a fixture; private agreements and UCC security labels did not change that tax result.

1966-11-29

Was a business-asset sale-and-leaseback merely secured financing, or did title pass so the leaseback or conditional sale became taxable?

The memorandum treated title as passing based on the documents and licensing facts, making the leaseback or conditional sale taxable rather than a loan.

1966-11-28

Can a retailer donate tax-free merchandise that was acquired under a resale certificate?

Potentially, but the property must first be legitimate resale inventory. The source says unsalable inventory may be discarded without tax and later notes a section 6403 exemption for qualifying…

1966-11-28

Could a catalog retailer exclude charges for moving customer orders from its mail-order facility to its own retail stores for pickup?

No. Moving goods between the retailer's own facilities was not direct delivery to the purchaser or a place where the purchaser or representative received control.

1966-11-17

Did monthly newsletters distributed to members of San Francisco professional-engineering sections qualify as exempt periodicals?

Yes under the 1966 analysis. The described monthly member newsletters qualified under former section 6362 and Ruling 50.

1966-11-17

Did an out-of-state insurer have to register and collect use tax on stationery and supplies sold to its California agents?

No on the stated insurance-business sales to authorized agents. But sales to brokers, other persons, or agents for noninsurance use would require registration and collection.

1966-11-17

Was the section 6476 prepayment penalty measured by the required prepayment or the larger advance payment actually made?

It applied only to the amount the taxpayer was required to prepay, not the amount of any advance payment actually made.

1966-11-16

Could a magnetic-tape maker buy methyl ethyl ketone, methyl isobutyl ketone, and trichloroethane for resale?

No. The ketones applied the oxide coating and trichloroethane thinned its lubricant, so all three were taxable manufacturing solvents.

1966-11-15

Was Surgicel absorbable cellulose hemostat exempt as medicine?

Yes. California treated the fabric like an absorbable suture because it stopped bleeding at the applied site and the body absorbed it within about 15 days.

1966-11-15

Were charges taxable for screening and separating customer-furnished rock, and what if the work also included crushing or mixing?

Screening or sorting alone was not taxable fabrication. Crushing or mixing was taxable processing, and combined charges were fully taxable unless sorting was specifically separable.

1966-11-14

Was equipment 'used' for California tax purposes when it was held available as standby replacement property but never physically operated?

Yes if it was actually held for standby replacement. Mere purchase followed by resale was different when the property was never installed or made available for standby use.

1966-11-07

Did completing an aircraft in California and returning it for occasional visits make the aircraft subject to California use tax?

Not if completion was its only California contact and, after out-of-state delivery, it spent no more than half of its first six post-entry months in California.

1966-11-04

Was pumping ready-mix concrete from a truck through hoses or pipes to the jobsite placement point treated as installation or transportation?

Pumping was transportation. Supplier charges were generally taxable absent earlier title passage; the described unrelated operator arrangement was generally treated as a taxable equipment rental.

1966-11-02

Did a $100,000 compromise paid by guarantors eliminate bad-debt relief on a much larger taxed credit sale?

No. The unpaid taxed selling price beyond the verified compromise could be a bad-debt loss rather than a discounted sale of the receivable.

1966-10-18

Were a caterer's charges for bartenders, waitresses, and cooks excluded from taxable meal receipts because the workers were classified as independent contractors?

No. Their independent-contractor status did not exclude the charges because the caterer billed customers for labor used to serve meals, which ruling 53(e) included in the taxable charge.

1966-10-17

Was operating a high-energy radiation facility taxable when customers brought samples for experimentation and received operators, advice, readings, and equipment use?

No. California treated the facility operation as a service because it transferred no property, report, or fabricated customer product.

1966-10-17

Could a construction joint venture remove freight from use tax when lumber was ordered F.O.B. jobsite for a delivered price but shipped freight collect?

No. Freight remained part of the delivered sales price regardless of who paid the carrier, and netting it from the seller's invoice did not reduce the use-tax measure.

1966-10-10

Were separately invoiced lumber sorting and delivery charges taxable after goods reached a compound near a construction site?

Sorting was taxable processing and a service forming part of the sale; delivery could be excluded where title passed before transportation.

1966-10-10

When did computer work produce a taxable item rather than a nontaxable information service?

Simply putting customer data onto punch cards or other property was taxable. Developing information or evaluating data was a service, with delivered cards treated as incidental.

1966-09-28

Did transferring all assets of one selling activity qualify under section 6006.5(b) when the same corporation retained a separate textile manufacturing plant?

No. Staff treated all permit-requiring activities as one property pool, so transferring the merged cotton-ginning assets while retaining a Georgia textile plant failed. It suggested a single…

1966-09-27

Did a bank's quarterly financial statements, year-end preview, and separate annual report all qualify as one exempt periodical series?

Under the 1966 analysis, the quarterly statements and year-end preview qualified; the separate annual report apparently did not.

1966-09-27

Did adding a side-shifter that let forklift tines move laterally substantially change the truck for lease-tax purposes?

Yes. The attachment materially increased function and rent, so the modified forklift was substantially changed and its California rent was taxable.

1966-09-22

Was a separately billed overtime amount taxable when a buyer's delayed delivery required a materials seller to keep employees after hours?

Yes. The overtime reimbursed the seller's labor expense and was a service forming part of the material sale, so separate billing did not exclude it.

1966-09-22

Were patented-process royalties taxable when a licensee also had to lease the licensor's equipment to use the process?

Yes. The licensee could not use the leased coating equipment as intended without paying the royalties, so both royalty and rental receipts were taxable.

1966-09-21

Did use tax apply when four aircraft co-owners sold a fractional interest to a fifth person?

Yes. Assuming the original owners held the aircraft as tenants in common, the fifth person purchased an interest in tangible personal property and owed use tax measured by the amount paid for that…

1966-09-16

Did the vehicle exemption in section 6388 apply to house cars?

No. The memorandum treated house cars as passenger vehicles under Vehicle Code section 465, not as a vehicle type covered by section 6388.

1966-09-13

Did a contract postponing title and final acceptance until Tennessee prevent tax when the buyer took the tooling from the California seller and hauled it away?

No. Tax counsel treated the California handoff to the buyer as a taxable in-state delivery; postponing title until Tennessee operated only as the seller's retained security interest.

1966-09-06

Were a location caterer's charges for a driver waiting after the first meal taxable when the charge arose only if the customer did not order a second meal?

No. Tax counsel treated the stand-by charge as payment for the driver's waiting time, not for preparing or serving food, because it arose after the first meal and only when no second meal was ordered.

1966-09-01
