Could a mortgage lender subtract Fannie Mae and Freddie Mac risk fees withheld from loan-sale proceeds when calculating Washington B&O gross income?
No. The withheld credit fees and loan-level adjustments were selling expenses included in total consideration, not deductible reductions of gross income.
Were federal Universal Service Fund high-cost support distributions taxable Washington gross income even though the carrier also contributed to the fund and charged customers a surcharge?
Yes. Support distributions compensated the carrier for serving high-cost areas and were separate from mandatory contributions based on interstate and international revenues. The carrier's voluntary…
Could a snack distributor deduct off-invoice price reductions when retailers had merchandising and promotional duties tied to the discounts?
No. The distributor did not prove the reductions were unconditional bona fide discounts rather than compensation for retailer display and promotion obligations.
Could nutritional-supplement distributors report paystub amounts labeled retail commission, wholesale profit, and royalty override under matching Washington B&O classifications?
No. The labels did not control the actual activity. Each payment was calculated from product sales made through the direct-seller network and was commission income, not the distributors' own retail…
Did an online sports retailer establish Washington nexus when a representative visited teams a few times yearly only to conduct uniform-sizing nights?
Yes. The visits helped maintain the Washington market, and the retailer did not prove that other internet sales were disconnected from that nexus-creating activity.
Could a credit-card processor exclude interchange fees from Washington B&O gross income because the fees were netted before receipt or paid through to its sponsoring bank?
No. The processor was legally entitled to the merchant discount and contractually assumed responsibility for interchange fees, making them a nondeductible cost of its processing business even when…
Did Washington properly tax and apportion an out-of-state parent company's reimbursements for management and human-resources services provided to affiliates?
Only partly. CEO-and-staff reimbursements were gross income, but none was attributed to Washington because every affiliate was domiciled elsewhere. Amounts allocated to the parent for its own…
Could a nationwide mortgage servicer reclassify ancillary fees away from loan servicing and exempt subservicing payments from an affiliate?
No. The supported fees arose from loan-servicing functions, unsupported accounts lacked proof, and the affiliate exemption failed because the servicer was not a member bank.
Could a commercial-property seller calculate Washington REET from a tenant's cash purchase price equal to only 34% of the county assessed value?
No. Even though the landlord and tenant were unrelated, the 66% discount rebutted the presumption that the cash price was true and fair value. Explanations for accepting the offer did not establish…
Did grinding machines qualify for Washington's M&E exemption when they sharpened old tools and also made new parts and tools?
No. Sharpening existing tools was nonqualifying repair use, and the taxpayer did not document that qualifying manufacturing exceeded 50% of total use.
Could Washington estimate a restaurant's cash sales from observed payment patterns and impose an evasion penalty for omitted POS cash transactions?
Yes. The observation-based estimate was reasonable, and missing cash sales despite issued receipts and known tax duties proved intentional evasion.
Did Washington retail sales tax apply to one-price wedding, event, meal, and bed-and-breakfast packages?
Yes. The packages combined separately identifiable retail and nonretail products for one nonitemized price. Prepared meals made the pre-2014 packages taxable bundled transactions, and transient…
Could a smoke-shop owner defeat an estimated tobacco-tax assessment by saying old inventory belonged to a successor LLC and Department mail disclosed its information?
No. Missing purchase and inventory records supported the estimate, the old sole proprietorship remained liable, and mailing its own assessment was not a disclosure.
Could a Washington employer-of-record exclude affiliate payroll repayments as paymaster reimbursements or apportion them to out-of-state managed properties?
No. Contemporaneous records showed collective group control, not sole control by each affiliate, so neither the reimbursement exclusion nor paymaster deduction applied. The service benefit was…
Did unfinished lab space and nuclear-reactor research qualify for Washington's high-technology sales and use tax deferral?
No. The unfinished area remained in project square footage but was not common space, and nuclear power was expressly excluded from alternative energy.
Did a musical-entertainment company prove accountant fraud sufficient to waive penalties on late 2015 and 2016 Washington annual returns?
No. The company offered its own allegations and a small-claims filing made after the review hearing, but no contemporaneous evidence proving fraud. It also ignored repeated Department calls and…
Were a homebuilder's separately contracted design fees taxable as retail construction services when it later built nearly every project?
Yes. Contract credits, integrated marketing, and the builder's signature-home model showed both parties contemplated that it would perform design and construction.
Did Washington litter tax apply to toilet tissue, towels, napkins, facial tissue, and copy paper sold in bulk for commercial or institutional use?
No for the products proved here. They were designed, marketed, priced, and packaged in quantities for industrial, commercial, and institutional customers—not home or personal use—so they were not…
How did Washington attribute receipts from custom dam-control software used in two states and an IT staff-augmentation subcontract performed in Washington?
The software-contract receipts had to be reasonably divided between Washington and the one out-of-state plant where the software was actually used; Audit could not assign 100% to Washington, but the…
Could an out-of-state transportation company waive Washington REET delinquency penalties because neither it nor its consultants knew an indirect acquisition triggered a controlling-interest transfer?
No. Lack of knowledge, consultant mistakes, good faith, and absence of evasion were not circumstances beyond the taxpayer's control. The 24-month waiver also did not apply because the penalty arose…
Were a nonprofit's year-round web, phone, and email sales of environmental commodities exempt Washington fundraising activities?
No. The web store and regular customer-service hours constituted a regular place of business, even without a Washington location. Reliance on legal counsel did not support cancellation of interest…
Was a bankruptcy trustee's court-approved auction of a 50 percent interest in a real-estate-owning LLC exempt from Washington REET?
No. The auction was not a mortgage, deed-of-trust, lien-foreclosure, or judgment execution; LLC members were not tenants in common in the real estate; and a trustee's sale was not a sale by the…
Must Washington waive a late-payment penalty when a taxpayer mails a check on the due date but USPS postmarks it two days later?
No. The USPS cancellation mark controls, and taxpayers must mail sufficiently early to obtain a timely postmark. A routine postmark delay was not a circumstance beyond the taxpayer's control.
Could a carbon-fiber manufacturer receive another extension after filing its Washington tax-preference survey two days late despite already receiving the one-time 90-day extension?
No. Employees being busy with a Department deferral audit was not an immediate or emergency circumstance beyond the taxpayer's control, and employee error did not qualify. The taxpayer had already…
Could Washington estimate a used-car dealer's sales from licensing records and book values, and impose an evasion penalty for collected but unremitted sales tax?
Yes. The dealer's files were incomplete, so licensing records and book values were reasonable estimates. Its own report showed knowingly collected sales tax was not fully remitted, supporting the…
Could a Washington computer shop back sales tax out of customer totals when invoices did not state tax separately but all prices were advertised as tax included?
Yes. Customer letters, dated online ads, product materials, and credible testimony proved the shop advertised tax-included prices, so the advertised total was not the statutory selling price.
Was a footwear company a wholesaler when a host retailer's cashiers sold its merchandise through the host's POS system under an agreement denying agency?
Yes. The host retailer sold in its own name and the contract expressly rejected agency, so the footwear company was deemed to sell wholesale to the host and its B&O base was the recorded retail price.
Could an equipment lessor avoid Washington sales tax with generic servicer affidavits or by expecting vehicle buyers to pay use tax when registering?
No. Lease-tax proof had to identify particular transactions and payments, and vehicle-registration use-tax authority did not relieve the seller's collection duty. Documented auction and resale…
Was a cloud business platform priced as a percentage of sales exempt from Washington use tax as data processing?
No. Inventory management, communications, analytics, and point-of-sale reporting formed an integrated software business solution beyond extracting or converting customer data.
Did a Washington propane seller owe use tax on two unusually large tanks it acquired for unpaid storage rent but intended to resell without using?
No. The credible evidence showed a resale purpose and no intervening use; although unusually large, the tanks remained in the same class of propane tanks the business regularly sold or leased.
Did structural high-bay warehouse racks qualify for 100% construction-cost remittance rather than the 50% racking-equipment remittance?
No. Although the racks supported the building, their primary purpose was storing finished goods, so only the 50% racking-equipment remittance applied.
May a Washington used-car dealer claim bad-debt tax relief on the full unpaid loan balance after repossessing the vehicle?
No. Sales-tax credits, use-tax credits, and B&O deductions for bad debts must exclude the value of repossessed property taken in payment of the debt.
Did major employee departures under a voluntary separation program justify a late annual survey for Washington's fruit-and-vegetable manufacturing B&O exemption?
No. The taxpayer had already used its one-time 90-day extension, and planned personnel turnover over a 12-month program was neither immediate, unexpected, nor unavoidable. It could reasonably have…
Was a parents-to-daughter transfer of a controlling LLC interest exempt from Washington REET as a gift when rental income continued paying a mortgage owed by the parents?
No. After the transfer, rental income belonging to the daughter reduced mortgage debt for which the parents remained liable, providing consideration and defeating the gift exemption.
Did human identity verification make an SSL digital-certificate service primarily human effort and exclude it from Washington digital automated services tax?
No. Humans performed initial verification, but the continuing certificate service was automated, and the taxpayer's cost analysis included indirect or unexplained expenses that did not prove the…
Could a Washington speculative builder avoid deferred sales or use tax when vendor contracts required tax but the invoices did not separately state it?
No. Retail sales tax had to be separately stated on each invoice; a private subcontract clause did not overcome the conclusive presumption that an unstated selling price excluded tax.
Did a Washington business owe use tax on a tractor when a private lender paid the dealer's sales-tax-inclusive price and the business repaid the lender?
No. The lender financed the business's purchase, never possessed the tractor, and paid retail sales tax at the dealer. Because that tax was included in the loan the business repaid, the tractor was…
Could a Washington chiropractor sell recommended dietary supplements without sales tax under the prescription exemption?
No. Chiropractors could recommend and sell supplements but were not authorized to prescribe or dispense them, so retail sales tax and retailing B&O tax applied.
Did buying all assets of a defunct answering-service business make the buyer liable for its unpaid Washington taxes?
Yes. The buyer acquired more than 50% of the assets and failed to prove all tangible and intangible assets were worth less than $50,000.
Were a financial institution's mortgage subservicing fees apportioned to where its staff worked or where the borrowers were located?
Borrower location. The nature of the work was loan servicing even though the company was a flat-fee subservicer without servicing rights or borrower contracts.
Could a dentist reduce Washington use tax on purchased practice equipment by claiming the contract price exceeded the equipment's true value?
No. The arm's-length contract allocation and the same amount used for federal depreciation were persuasive evidence of value, while a later appraisal and unsupported missing-equipment claim did not…
Did Washington's 50% reseller-permit misuse penalty apply when a builder let vendors use its permit on taxable speculative-construction purchases?
Yes. The builder knew vendors kept its reseller permit on file, did not identify taxable speculative-project purchases, paid no sales tax, and failed to prove the permit had not been improperly used.
Could apartment projects exempt 75 percent of construction costs because their federal low-income housing agreements required 75 percent farmworker occupancy?
No. The complexes also regularly rented commercially to the general public, and no particular units were segregated for farmworkers. The agricultural employee housing exemption did not apply to any…
Could a marijuana seller prove undocumented sales were wholesale through buyer websites, storefront photos, bulk quantities, and its good-faith belief that buyers were retailers?
No. Without reseller permits or contemporaneous verification, the seller needed transaction-specific supporting documentation. Incomplete buyer records, unregistered or closed buyers, and sales…
Did an out-of-state distributor create Washington B&O tax nexus when employees visited customers only a few times per year to maintain relationships?
Yes. Employee visits to six to nine Washington customers over two to six days, no more than three times per year, were significantly associated with maintaining the distributor's market. Physical…
Could a Washington naturopathic clinic exclude from B&O-tax gross income the patient payments it passed to independent-contractor practitioners?
No. Independent-contractor status did not create an agency relationship, and the clinic did not prove patients separately owed the practitioners, so the full patient receipts were taxable gross income.
Were purchased business-integration services taxable, was lack of intent enough to waive a penalty, and did work in a foreign trade zone qualify for Washington's stevedoring B&O rate?
The Department answered yes, no, and no. Commercially offered digital automated services were taxable even if characterized as telecommunications; lack of intent did not establish circumstances…
For REET on a 50% LLC interest transfer, which county value controls, and is tax measured by 50% or the full value of the underlying real estate?
Use the county assessment publicly available when the transfer occurred, not a later value. But once the 50% transfer qualified as controlling, REET was measured by the full value of the entity's…
Was an out-of-state vehicle-warranty provider liable for Washington retailing B&O and sales tax when dealers sold its contracts to car buyers?
Yes. The provider remained the actual warrantor and controlled the contracts, while dealers acted as third-party selling agents rather than resellers. The provider owed retailing B&O and uncollected…
Could an office-building seller reduce Washington REET below an arm's-length sale price by appraising the property at market rent and treating above-market tenant leases as personal property?
No. The actual consideration in an unrelated arm's-length sale presumptively established true and fair value. An appraisal that ignored valuable in-place leases did not value the property as sold.…
When do Washington motel guests become nontransient tenants, and must a motel remit Tourism Promotion Area charges it collected from them?
Guests who contract and pay in advance for at least 30 continuous days can be nontransient from day one; guests who extend later are transient for the first 29 days. Any TPA charge actually…
Did engineering, permits, bonding, project management, rented installation equipment, and a weather station qualify for Washington's solar-energy sales tax refund?
No. The exemption covered qualifying generation equipment and actual installation labor, not design, planning, permits, bonds, project management, or rented forklifts and safety equipment. The…
Did replacement pad-mount transformers purchased for existing wind turbines qualify for Washington's renewable-energy machinery sales tax exemption?
No. The transformers restored malfunctioning turbines to normal operation without increasing productivity, improving efficiency, or extending useful life beyond normal. They were excluded repair or…
Could an engineering firm buy prototype materials tax-free as manufacturing components or claim the M&E exemption as its clients' processor for hire?
No. The prototypes were tangible representations of contracted engineering and product-development services, not products manufactured for sale, so the firm consumed the materials. It also bought…
Could a construction contractor use Washington's four-year assessment period after collecting sales tax, reporting no business, and keeping the tax, or claim undocumented tax-paid-at-source deductions?
No. Collected sales tax held in trust but not remitted, plus false no-business returns, established the statutory misrepresentation exception. The contractor also lacked invoices separately stating…
Are a rock seller's delivery charges included in Washington use tax when a government contractor buys and uses the rock on a federal project?
Yes. Use tax is measured by purchase price, which adopts the retail sales-tax definition of selling price and does not deduct seller delivery charges. Because the same vendor sold and delivered the…
Should Washington apportion programmatic internet-advertising receipts using internet-user population or the general population?
Internet-user population. With no actual location data, it more accurately represented the customers' online market and where their internet sales activity received the benefit of the advertising services.
Were percentage payments from an in-store shoe department tax-free real-estate rent, and could the host stores treat merchandise sales as an agent's sales?
No. The shoe company lacked exclusive control, so its space was licensed rather than leased. The stores sold consigned goods in their own name and had to report B&O tax and remit collected sales tax…
Was a subscription service that supplied grass-sod dog trays and regularly replaced the soiled sod subject to Washington retail sales tax?
No. The provider delivered its own tray and sod, then removed and replaced the soiled sod; it did not clean customer property or a building. The receipts belonged under service B&O, and warrant…
Were toll-free call-tracking services bought for apartment listings excluded from retail tax as data processing or advertising services?
No. The purchaser primarily bought access to toll-free numbers billed by call minutes and recording fees. Caller reports were incidental to the telecommunications service, and the separate…
