Could a ranch's net-metered solar facility qualify for California's farm-equipment partial exemption?
Yes, on the stated facts and assumptions: it was designed to power qualifying irrigation equipment, and more than half its annual output was consumed by that equipment.
Are rentals taxable when tax-paid software is loaded onto a tax-paid computer before the combined unit is leased?
No, under the stated assumptions. Merely loading the software did not substantially change the tax-paid components, so no further tax was due on the rentals.
Under the California NOL suspension rules addressed in this ruling, when did a loss receive an extended carryover period, and which loss was used first?
Only an NOL deduction actually denied, in whole or in part, by the suspension provisions received an extended carryover period. NOLs were applied oldest first, so a later loss waiting behind an…
Could an online advertising company use customers' ordinary-course billing addresses as a proxy for commercial domicile under the former cost-of-performance regulation?
Yes, on the company's unusual facts. Payments to third-party website publishers had to enter the post-2007 cost-of-performance analysis, but the contracts and ordinary-course records did not locate…
Which laboratory products qualified for California's exemption for containers used to collect or store human blood products?
Only the described integrated blood-bag collection system qualified. The listed specimen, testing, transfer, disposal, and machine items did not.
When did a business solely owned by a deployed service member 'cease operation' for the California minimum-tax exception addressed in this ruling?
A qualifying corporation or LLC could cease operations by winding up without active business, filing final returns and delivering its dissolution or cancellation certificate, having no gross income…
When were payments to a nonresident former insurance agent for California services excluded from California income and withholding under this ruling?
Payments for services performed in California remained California-source income, but a nonresident full-time life insurance agent could exclude substantially equal periodic payments made at least…
Was an out-of-state owner doing business in California when its disregarded QSub or single-member LLC conducted California business?
Yes. When a QSub or other entity disregarded for California income and franchise tax purposes conducted activities that constituted doing business in California, those activities were treated as the…
How broadly did California interpret the section 33 exemption for blood, human body parts, banks, and medical purposes?
Blood, plasma, blood products, and derivatives were exempt without a bank condition; human body parts were exempt when held in a lawful repository for broadly defined medical purposes.
Did California's franchisor apportionment regulation apply to trademark licenses for manufacturing, distribution, and retail, including royalties from water's-edge affiliates?
Yes. The company licensed trademarks for licensees to manufacture, distribute, or retail products under methods and procedures the company prescribed and monitored, so the activity was the business…
Were commodity-linked swaps, structured notes, options, futures, and forwards qualifying investment securities for California investment-partnership rules?
Yes. FTB treated all the proposed commodity-linked derivatives—including index- or single-commodity swaps, structured notes, options, futures, and forwards—as qualifying investment securities.…
Did an out-of-state dealer's California trade-show setup or teardown day count toward the historical 15-day safe harbor?
Not if the dealer merely set up or tore down. A day counted if the dealer conducted dealer-to-dealer business, and other California activities could independently create a collection duty.
When could an out-of-state vehicle lessee credit another state's tax against California use tax on lease payments?
Only when the lessee paid documented tax or reimbursement imposed on the same lease payment California taxed. Tax on the lessor's purchase, title, or registration did not qualify.
When can a vehicle lessee credit another state's tax against California use tax on lease payments after the vehicle enters California?
Only when the lessee paid tax or reimbursement on the same lease receipts and for periods also taxed by California—not tax imposed on the lessor's purchase or registration.
Who had to recapture a partnership's former California farmworker housing credit when a partner sold its interest before a later disqualifying event?
The partnership and the partners who held interests when the disqualifying event occurred bore the recapture. The current partners owed their distributive shares even if one had not received the…
Did six planned corporate distributions satisfy California's section 355 active-business rule, preserve their stated form, and avoid the noneconomic-substance penalty?
Yes, subject to the submitted facts and representations. Six distributions satisfied the section 355(b) active-trade-or-business requirement under California's then-current conformity date. FTB…
Could a corporate general partner attribute its partnership's active business to itself to satisfy California's pre-TIPRA section 355(b) spin-off test?
Yes, for the narrow purpose ruled on. FTB applied Revenue Ruling 2007-42 to attribute the active business conducted by a partnership during the five years before the distribution to its significant…
How did a California combined-report member calculate REMIC excess-inclusion income and its net operating loss carryforward?
FTB said the REMIC residual-interest holder's minimum taxable amount for California purposes was determined after apportionment: its federal excess-inclusion minimum was multiplied by the member's…
Do medicinal claims turn herbal tea or another food into taxable medicine, and when is a ground herb treated as a supplement?
No. The memorandum said claims alone do not convert food into medicine; cut-leaf herbs are not powder, while herbs ground into fine particles require the separate supplement analysis.
Did medicinal claims on a food label make the product a taxable medicine, and when did herbs become supplements rather than exempt foods?
No. A product had to meet Regulation 1591's medicine definition; label claims alone were irrelevant. Supplement status separately depended on product form, labeling, or nutritional design.
When a California state tax lien expired after ten years, did the underlying sales-tax debt become wholly uncollectible by every involuntary remedy?
No. The lien could not be revived and several lien-dependent remedies ended, but the memorandum said each remedy had its own limit and a notice of levy could still be used.
How was gain from a California-only section 338(g) deemed asset sale apportioned and reported when the target joined the buyer's federal consolidated group?
The target filed a pre-sale and a post-sale short-period return, not a separate one-day return. The section 338(g) gain was apportioned using factors tied to the instantaneous deemed asset sale: no…
Would California treat a proposed section 355 stock distribution as tax-free when the distributing corporation acquired the controlled corporation's same-line business through a taxable stock purchase within the prior five years?
Yes, on the submitted facts and while the favorable IRS private letter ruling remained valid. Although California had not adopted the new federal separate-affiliated-group rule, FTB treated the…
Can same-year dividends passed through several fully included members of a California unitary group be eliminated under section 25106, and which earnings-and-profits layers fund the dividends first?
Yes. Dividends passed from lower-tier subsidiaries through intermediate corporations to the ultimate parent in the same tax year were treated as unitary income and eliminated under Revenue and…
Could the third dividend in a three-step chain be eliminated under section 25106 when the first dividend came largely from pre-acquisition E&P of subsidiaries that had already been unitary with each other?
Yes, subject to the ruling's factual assumptions. The first dividend came from E&P accumulated while the lower-tier payor and recipient were members of their earlier California unitary group. That…
Would liquidating an active-business subsidiary into the parent allow the parent to satisfy California's pre-TIPRA section 355 active-business test, and would the related restructuring trigger the section 19774 NEST penalty?
Yes, on the submitted facts and representations. Because California had not adopted the federal separate-affiliated-group rule, the parent liquidated an active-business subsidiary into a disregarded…
Were interest receipts generated by independent investment managers included in a California manufacturer's sales factor when the managers acted on its behalf and employees provided only minimal oversight?
No. The outside investment managers' activities were performed on behalf of the taxpayer and therefore were not the taxpayer's own income-producing activities under Regulation 25136(b). The…
Were fees for training clients to use and reproduce materials from returnable master printing plates taxable, and how were seminar materials treated?
Plate-use and license fees were taxable rent. Significant classroom instruction could be nontaxable, but separately charged training materials were taxable sales.
Could an event planner treat separately stated management fees as nontaxable when it bought food, gifts, and other property as its client's agent?
Yes, if it was a true disclosed agent: agency was written, vendors knew the named client, the client paid exact vendor cost, and the planner met the other stated conditions.
When could an event planner buy meals, gifts, and other property as its client's agent without taxing its management fee?
When it had written agency evidence, disclosed the client and agency to vendors, passed through the same cost, and acted consistently with that relationship.
Was a data-recovery company's charge taxable when it returned restored data on the customer's drive, online, or on replacement media?
Usually no, because the true object was data recovery. But a separately stated charge for a replacement drive was taxable, subject to a possible tax-paid purchases resold deduction.
Does income from an activity that national banks cannot conduct count as financial income merely because it is interest or gain resembling income earned by a bank?
No. For the financial-corporation gross-income test, FTB looked to the business activity that produced the income, not merely the income's character. The broker-dealer conducted certain…
How did California tax an out-of-state motorhome exchange that failed Lemon Law and returned-merchandise requirements?
An earlier staff memorandum said the $12,000 upgrade would be the California tax measure if the original motorhome had been used substantially outside California. The opinion did not locate or…
How specific did a California-bound truck's assigned payload need to be for first use to occur out of state?
A fixed pickup time, date, and location could be enough; serial-number identification was unnecessary. Dispatch for the next available load was not enough.
How did volume-commitment discounts and upward adjustment charges affect the taxable measure under one enterprise agreement?
Qualifying discounts reduced the taxable measure to the extent earned from taxable property purchases; shortfall charges increased taxable gross receipts.
Were automobiles exempt when nonresident buyers hired common carriers to pick them up in California and deliver them out of state?
For the linked automobile letter, yes if the contracts required out-of-state shipment and buyers took no California possession; the live annotation instead describes an auctioneer and adds a use-tax…
Could an MTE lessor claim a refund for tax reimbursement paid on California repair parts described in its lease as resold to the lessee?
No. The lessor was the consumer of the MTE and its component parts, had no valid fair-rental-value election, and was not the proper claimant for tax paid to retailers.
How did California apportion deemed-asset gain from IRC section 338(h)(10) and 338(g) stock-purchase elections?
The result depended on the election and the target's position in the selling federal group. A section 338(h)(10) target's gain was included in the seller and target's California combined report and…
Did an included unitary affiliate's subcontracted work count when locating a contractor's greater costs of performance for California sales-factor purposes?
Yes. When the contractor and subcontractor were members of the same unitary combined-reporting group, FTB treated the affiliate's work as part of the contractor's income-producing activity. An…
Should property, payroll, and sales tied to income excluded from California's tax base remain in the apportionment factors?
No. FTB said the apportionment formula should reflect only activities that produced business income included in the tax base. Factors tied wholly to exempt income were removed from both numerator…
How much of a $29 delivered-and-installed air-filter charge was taxable when delivery alone cost $19?
$19 was taxable as the filter's delivered selling price. The remaining $10 was excluded only if it was solely for installation labor.
Were dividends passed from controlled foreign corporations through domestic parents to the ultimate parent eliminated under section 25106 when every entity was fully included in a worldwide California combined report?
Yes. Dividends from controlled foreign corporations to their domestic parents, followed immediately by dividends of the same amounts to the ultimate parent, created unitary income at each tier and…
Were vents and sumps used temporarily during heart-bypass surgery exempt prescription medicines?
No. They were temporary surgical appliances used to clear blood from the operative field, so they were excluded from medicine and their sales were taxable.
When were off-reservation sales exempt after carrier or contract-dealer delivery to Indian purchasers on reservations, and were pre-delivery certificates valid?
Exemption required title and possession to pass on the reservation with documented delivery. The sampled pre-delivery certificates were invalid because they attested to future events.
Did a retailer satisfy California law after mistakenly collecting tax reimbursement on exempt sparkling cider and already remitting it to the Board?
Yes, as to remittance. The retailer had not retained the money; it complied by paying it to the state, and any recovery had to proceed through the retailer's tax-refund claim.
Could a title-passage statement in a written estimate establish when ownership transferred if the customer authorized the job verbally and no signed contract existed?
Yes. California said an accepted estimate stating that title passed at the time and place of shipment satisfied the title-passage requirement for the described reassembly issue.
Did property owners become owners of promotional posters placed on their walls without advance permission, allowing the printer's sales to qualify for exemption?
Yes on the stated assumptions. Once posted, property owners had dominion and control and could remove or dispose of the posters, so title transfer was unnecessary.
How did California test an MTE lessor's fair-rental-value election after a nonleasing use?
A timely election was valid after six months of lease-only use. Any nonleasing use triggered purchase-price tax with FRV offsets; six months without leasing established a substantive change.
How did California apply sales tax to carbonated and noncarbonated fountain drinks sold by stores without customer dining facilities?
Carbonated fountain drinks were taxable and noncarbonated drinks were exempt; merely drinking while shopping did not make the store a retailer-provided consumption facility.
Could a taxpayer who moved out of California use capital losses from securities sold while she was a California resident against gain from a later sale of her California home?
Yes. The capital losses were California-source losses because the taxpayer was domiciled in California when she sold the securities, so the later move did not change their source. The gain from…
Must a publicly traded mortgage REIT include its wholly owned section 856(l) elected subsidiary in a California combined report when the entities conduct a unitary business?
Yes. The REIT was subject to California corporation franchise and income taxes, and its section 856(l) elected subsidiary was taxable as a corporation for federal and California purposes. Each…
After one unitary group acquired another, which dividends from the acquired subsidiary through its parent to the buyer qualified for section 25106 elimination?
Some did and some did not. The acquired lower-tier subsidiary's dividend to its longtime unitary parent qualified under section 25106 because it was paid from income of their preexisting unitary…
When were earnings on temporarily invested IRC section 965 repatriated dividends apportionable California business income?
The interim earnings were apportionable business income when the repatriated dividend funds were specifically earmarked for an operational use in the taxpayer's unitary business. Company A's plan…
Could numerous trusts qualify for California's 2005 tax amnesty by submitting agreed electronic return data and payments by June 30, 2005, after FTB-related filing-format delays?
Yes, for this taxpayer's 2005 amnesty filings. FTB ruled that the trusts would satisfy section 19733(a)(3) and qualify for amnesty under section 19732 if the required electronic return information…
Could a California vehicle buyer credit an out-of-state tribal sales tax against California use tax?
No. The tribe taxed under its own sovereignty, not as a state political subdivision, and the buyer's tribal-tax reimbursement was also included in the vehicle's California use-tax measure.
When did California's historical personal-service time-spread method apply instead of the ordinary cost-of-performance rule?
The time-spread method applied when capital was not a material income-producing factor in the service. A computer-system consulting contract performed mainly through employee labor qualified, so…
Were sales and rentals of a knee scooter exempt as a prescription mobility device?
Yes when sold or leased to an individual for that person's own use as directed by a licensed physician. The retailer should retain a written customer or physician statement.
Was a separately stated electronic-waste recycling fee included in the retailer's taxable gross receipts?
No. The fee was imposed on purchasers, and the retailer merely performed its statutory collection duty rather than passing a retailer expense to the buyer.
Could California correctional officials collect use tax from inmates when an out-of-state catalog retailer did not collect it?
Yes. The 2005 opinion said the inmate owed use tax on property shipped for use in California, and the state facilities could collect and remit it to the Board.
Could California grant interest relief after January 1, 2002 for section 6482 interest that accrued on a 1999 tax liability?
Yes. A post-2001 request could cover qualifying section 6482 interest on reporting periods beginning July 1, 1999 or later, even if the interest accrued before 2002.
