Was Washington required to use statistical sampling instead of taxing every sale for which an out-of-state seller lacked exemption proof?
No. Sampling is discretionary, and reviewing all available transactions was more direct; exemptions were allowed only where the seller supplied valid proof.
Did a company supplying workers and freight-handling services at client-controlled warehouses qualify for Washington's preferential storage-warehouse B&O rate?
No. The clients stored their own goods in warehouses they owned or leased and controlled. The contractor was paid for labor and handling, not for receiving third-party goods for storage, so its…
Could an aerospace machine shop use Washington's preferential B&O rate for parts covered by an airplane manufacturer's FAA production certificate?
Potentially. New documents established a basis for the rate, but the shop still had to connect each disputed sale to qualifying FAA-certified airplane parts.
Did stamping names on pet tags and embroidering pet collars constitute manufacturing for Washington B&O tax, even though the customization served one customer?
Yes for personalized items. Stamping and embroidery physically and functionally changed blank products into identification products. Unchanged, nonpersonalized items merely resold with loose…
Could a payroll processor deduct affiliated restaurants' employee-cost reimbursements under Washington's paymaster-services rule?
No. Records did not establish qualification for 2014–2015, and in 2016 the processor's control over health-plan eligibility created a disqualifying employment relationship.
Could a Washington equipment seller treat sales as out-of-state when its records did not show where the purchasers received the goods?
No. Sales delivered away from the seller are sourced where the buyer first receives the goods, but the seller must retain reliable delivery records. A summary list and invoices without out-of-state…
Could Washington estimate a restaurant's cash sales and impose an evasion penalty when its point-of-sale records were unreliable?
Yes. Missing transactions and unexplained data irregularities supported a 25% cash-sales estimate and clearly showed intentional underreporting.
Could Washington restaurant-bars treat drink prices as tax-included without signs and claim a sales-tax credit for food without itemized supporting records?
No. The restaurants neither posted visible tax-included notices nor separately stated tax on drinks. Their nonitemized and inconsistent food records also failed to substantiate a credit, so the…
Could a used-car dealer's managing member defeat a Washington trust-fund assessment by disputing the company's final sales-tax amounts or denying personal evasion?
No. The company's assessments were already final, and evidence showed it collected sales tax. As the highest-ranking manager, the member was personally liable for the trust funds and entity-level…
Are unstamped roll-your-own cigarettes subject to Washington cigarette tax, retail sales tax, and retailing B&O tax?
Yes. Roll-your-own cigarettes are statutory cigarettes, and the retailer produced no records or specific error analysis to overcome the estimated assessments.
Did a parking-lot reconstruction contract price include Washington sales tax when the bid mentioned tax but no invoice separately stated it?
No. Parking-lot reconstruction was retail construction, and no invoice separately stated sales tax. The quoted contract price was conclusively presumed tax-exclusive, so the buyer owed tax on the…
Were commissions from selling vehicle warranties, service contracts, and GAP waivers taxable under Washington's insurance-producer B&O classification?
No. The products were not insurance, the corporation itself was not licensed for the selling activity, and the commissions were taxable under service and other activities B&O tax.
Did Washington cigarette tax and penalties apply to unstamped roll-your-own cigarettes, and could the Department estimate sales from tube purchases and seized records?
Yes. Unstamped RYO cigarettes triggered cigarette tax and a remedial penalty. Tube invoices, sales logs, seized records, and the operator's own sales estimates supported the assessment, and knowing…
Could a print shop report as a duplicator rather than under Washington's printing-and-publishing B&O classification?
No. Audit observations and the shop's representative supported printing activity, while the taxpayer produced no contracts or records proving photographic duplication was its main business.
Can a corporation's president be personally liable for collected but unpaid Washington sales tax even if the accountant gave bad advice?
Yes. A corporate president is the chief executive and therefore a responsible individual under RCW 82.32.145. Liability for a current or former chief executive applies regardless of fault or…
Did collecting Washington retail sales tax for years without filing returns or remitting the money establish intent to evade despite alleged CPA misconduct?
Yes. Prior reporting history, collected customer tax, ignored Department contacts, and years without returns showed knowledge and willful nonpayment, satisfying the evasion standard. CPA discipline…
Did a signed export-facility certificate make log hauls to an inland storage yard deductible from Washington public utility tax?
No. The inland yard was not on navigable water, and another company made the last haul to shipside, so the legal requirements failed despite a valid certificate.
Could an aerospace-tooling seller claim Washington's preferential B&O rate for 2013 through 2015 after entering voluntary disclosure in 2017 and then filing late annual reports?
No. Annual reports were due by May 31 after each year the seller became eligible for the preference, not after it later registered or filed delinquent returns. Failure to register and report was…
Were a Washington developer's project-management fees and a repaid municipal stormwater fee part of the taxable retail construction contract price?
Yes on the published issues. The contracts made the developer responsible for construction, which was the predominant activity. The stormwater fee was also taxable because the developer paid it as…
Did an out-of-state vehicle purchase qualify for Washington's nonresident use-tax exemption when the buyer also lived and worked in Washington?
No. Her Washington home, employment records, and own statements showed more-than-temporary residency when she bought and used the car, even though she also lived elsewhere.
Could an online reservation service avoid penalties after voluntarily correcting three years of late apportionable B&O income?
Only for 2012. Good-faith correction was not beyond its control, but timely 2010–2011 returns supplied the 24-month history needed to waive the 2012 penalty.
Did a plat developer owe Washington's evasion penalty after repeatedly collecting sales tax, keeping it, and altering electronic invoice records?
Yes. The recurring unremitted collections and deliberate removal of tax and invoices from the records showed intent to evade, not an innocent software mistake.
Were software and data hosting with related IT support excluded from Washington retail tax as mere storage or a mostly non-retail bundle?
No. Customers used server processing and memory to run software and manipulate data, making the hosting and exclusively connected support taxable digital automated services.
Were a retail franchisor's percentage charges exempt real-estate rent when franchisees operated stores under extensive restrictions and the franchisor retained broad access?
No. The franchisees had permission to operate stores but lacked exclusive possession against the franchisor, so the charges were taxable service income. Good-faith reporting did not justify waiving…
Was an S corporation's property transfer to a former 50% shareholder exempt from REET as a mere change in ownership form?
No. The recipient had surrendered his shares months earlier, so he owned none of the corporation when it transferred the property and beneficial ownership changed 100%.
Could a restaurant-supply seller prove missing-permit sales were wholesale using only general information about its customers and product categories?
No. Without valid reseller permits or alternate documentation, the seller had to prove each disputed transaction. General claims that restaurants resold packaging were insufficient where invoices…
Did hauling import containers entirely within Washington qualify for the public utility tax interstate-commerce deduction without through bills of lading?
No. Port location alone did not prove interstate movement, and the carrier's forms lacked the through-shipment details needed to connect each local haul to foreign commerce.
Could an unregistered affiliate enter Washington's Voluntary Disclosure Program after the Department began an audit expressly covering the corporate group?
No. The affiliate's audit notices expressly applied to affiliates and required group action, so they were prior enforcement contacts. That made the applicant ineligible for the Voluntary Disclosure…
Could a broker-dealer waive delinquent penalties because it did not know annual B&O apportionment reconciliations were required and had timely monthly returns?
No. Reconciliations were required even with current data, lack of knowledge was not beyond its control, and missing prior reconciliations defeated the 24-month waiver.
Were vehicles bought out of state by a servicemember and spouse exempt from Washington use tax because they lived here only under military orders?
No. Federal law did not preempt the one-time use tax, and each vehicle entered Washington within 90 days after acquisition and out-of-state use.
Did an out-of-state domicile qualify a vehicle buyer for Washington's nonresident use-tax exemption when he also owned a Washington home, worked here, and spent months in the state?
No. A person may be resident in more than one state for use-tax purposes. The buyer used Washington addresses for business and tax matters, owned a home with his Washington-resident spouse, operated…
Did Washington have to consider tobacco-purchase invoices first produced with an appeal of an estimated OTP tax assessment?
Yes. The original estimate was authorized, but the operating division had to test the later invoices for authenticity and completeness and adjust tax if warranted.
Was an LLC's transfer of real property to a withdrawing member exempt from Washington REET as a federal tax-free liquidating distribution?
Yes. The member surrendered the entire interest for cash and property, and the filed returns showed no federal gain or loss, satisfying the REET exclusion.
Could a national title insurer overturn Washington's estimates of where services were received and what share of title-agent receipts it earned?
Only partly. Poor records made Schedule T sourcing reasonable, but contracts showing a 12% title-insurance share required review of Audit’s 18% estimate.
Could an affiliated payroll provider exclude payroll funding from Washington B&O gross income when it reported the workers as employer of record?
No. It supplied no evidence that affiliates controlled the workers or were liable to them in an enforceable writing, so it did not rebut the employer-of-record presumption.
Did the clean-alternative-fuel commercial vehicle credit allow 15 business days to submit final documents after receiving a vehicle?
No. The statute's unqualified word 'days' meant calendar days, and the Department had no discretion to accept final documents filed on day 16.
Was a dairy's new manure-handling system exempt as an improvement to its existing livestock nutrient management facility?
No. New gutters, curbing, piping, and a pit tank were construction of a new qualifying facility, not repair or improvement of pre-existing components.
Were automated recommendations telling retailers whether to accept customer and payroll checks taxable credit-bureau services or nontaxable data processing?
They were taxable credit-bureau services. The provider did more than convert client data: its algorithms evaluated fraud and loss risk so retailers could decide whether to accept or cash checks.
Could an online music-lesson business keep all out-of-state receipts in its Washington B&O apportionment denominator?
Only partly. Delaware receipts stayed because incorporation made the company taxable there, but receipts from other states were thrown out without proof of taxability or nexus.
Did municipal street-obstruction permits create taxable leasehold interests when contractors received exclusive control over defined portions of the public right of way?
Yes. The municipality's easement was a publicly owned real-property interest, and each permit identified a specific work area where the holder could obstruct the public and exercise dominion and…
Were CrossFit, yoga, children's movement, and lifetime-fitness classes taxable Washington physical-fitness services, and did an owner's overseas military deployment waive charges?
The class receipts were taxable retail sales because exercise, strength, conditioning, body maintenance, and lifetime fitness were their primary focus; yoga offered inside the fitness facility did…
Did a Washington resident owe use tax on a boat advertised in Washington on a trailer with Washington plates when the boat itself was always kept and used out of state?
No. The advertisement and trailer plate supplied enough facts to invoke the resident presumption, but the owner rebutted it with out-of-state title and tax records, seasonal moorage agreements,…
Did buying a failed restaurant's business assets make the buyer a Washington tax successor even after changing the name, cuisine, décor, phone number, and equipment?
Yes. The buyer acquired more than 50% of the predecessor's assets in a bulk sale; later discarding equipment or changing operations did not undo the acquisition. The predecessor's assessment was…
Could a convenience store avoid estimated other-tobacco-products tax when it kept no invoices for purchases from unlicensed distributors?
No. A retail license alone did not cover those purchases, and the Department reasonably estimated tax from available invoices, inventory, market prices, observations, and returns.
Could a product seller reduce Washington B&O gross proceeds for later distributor credits and handling allowances?
No. The full invoice price accrued before the credits, and handling allowances were unknown at sale and conditioned on delivery, stocking, and reporting services.
Could Washington estimate a restaurant's cash sales from auditor observations and impose the evasion penalty when most test purchases were missing or reduced in its records?
Yes. The observation-based 45% cash-payment estimate was reasonable, and missing or reduced cash sales plus collected but unremitted tax established intentional evasion.
Did Washington's apportioned B&O tax unconstitutionally discriminate against an out-of-state yogurt franchisor because another state also taxed some of the same gross receipts?
No. Washington imposed B&O tax for business in the state without different treatment based on the franchisor's location and attributed receipts from Washington franchisees under its apportionment…
Could a dentist exclude a tenant's half of shared building insurance and utilities from Washington B&O gross income as reimbursements?
No. The owner purchased insurance and utilities in his own name and was personally liable to the vendors. The tenant was not the sole obligor, and the dentist did not establish an agency…
Could an affiliated payroll provider exclude or deduct employee-cost funding when it reported workers as employer of record?
No. It lacked employee-by-employee proof that it had no payment liability and did not show that affiliates alone controlled employment decisions.
Could a mortgage company obtain a Washington penalty refund because an assessment mailed to its registered address was routed too slowly to its separate corporate tax office?
No. The Department mailed the assessment to the company's address of record, and an internal employee or mail-routing delay was not an immediate, unexpected emergency beyond the taxpayer's control.…
Could a manufacturer include 2010 invoices in a Washington retail-sales-tax refund claim filed in 2015 when it actually paid those invoices and taxes in 2011?
Yes, if substantiated. The four-year nonclaim period runs from when the tax was paid, not merely when the vendor invoiced it. Records showed most disputed 2010 invoices were paid in 2011, keeping…
Did a nonprofit's international youth-exchange program fees qualify for Washington's lower tour-operator B&O classification?
No. The organization's primary activity was administering exchange programs through partner organizations and host families, including recruitment, screening, orientations, insurance, training, and…
Were a homebuilder's profit-share payment and separately stated design fees taxable as part of its retail construction projects?
Yes. The contract made the 40% share of the home's net selling price compensation for constructing the house, not a separate investment commission. Design fees for two remodels were also retail…
Did a credit-card bank have pre-economic-nexus Washington B&O liability through an affiliate's merchant-network activity, and could Audit use single-factor apportionment?
The affiliate's Washington merchant enrollment and site visits created nexus because they built and maintained the market for the bank's cards. But Audit used the wrong formula for January through…
Could a sole proprietor and her wholly owned corporation be treated as one Washington taxpayer and obtain late-payment relief based on earlier family illnesses?
No. The separately registered sole proprietorship and corporation were separate persons, even with common ownership, and allocating each entity's income did not create double tax. The family…
Were three property transfers REET-exempt as mere changes in form when the original LLC went from owning 100% directly to owning only 50% of the recipient LLC?
No. The exemption required the grantee owners to hold the property in the same pro rata shares as before. The transfers gave two other owners a combined 50% interest, creating a real…
Were portable adaptive servo-ventilation devices exempt from Washington retail sales tax as prosthetic devices?
No. Portability was insufficient because the complete device did not have to be worn on the body; it was taxable durable medical equipment instead.
Could a convenience store reduce or waive an estimated cigarette penalty by blaming employees for prohibited single-cigarette sales?
No. Employee misconduct and lack of knowledge were not external good cause, and the one-carton-per-month estimate was reasonable without detailed sales records.
Did a vehicle seller owe tax on car washes bought for inventory and on an employee program allowing frequent swaps of rental cars?
Yes. Ordinary washes were consumed rather than resold, and daily vehicle swaps made the employee program an indeterminate series of short-term rentals.
Did Washington B&O tax apply when an out-of-state grower sold baby carrots delivered by third-party carriers to Washington customers?
Yes. The grower conceded Washington nexus and did not prove dissociation. Customers received the carrots at their Washington ship-to locations because possession by a separate carrier was not…
