Were organized speed-dating events taxable dating services even though the company described itself as an event planner?
Yes. The events, scorecards, and follow-up results were designed to introduce strangers seeking romantic partners or friends, so retail taxes applied.
How should an asphalt producer value self-manufactured road materials for Washington use tax, and did a canvas shelter qualify for the M&E exemption?
Comparable sales properly valued the materials, and the canvas shelter was an excluded building. Only later-year inflation adjustments were remanded for recalculation.
Could a dissolved technology business obtain a late annual-survey extension because its owner stopped checking the registered email, and could Washington add a delinquent penalty?
No extension, but the penalty was canceled. Failure to update and monitor email was within the taxpayer's control, while the survey statute allowed interest but not penalties.
Could a tree-service owner shift a Washington assessment from her reporting sole proprietorship to a closed LLC and defeat a bank-deposit estimate with an irregular receipt book?
No. Returns, account status, and deposits showed the sole proprietorship conducted the business, while the LLC reported no activity and closed. Because suitable contemporaneous records were missing,…
Could a manufacturer in receivership keep its Washington training B&O tax credit after missing the required annual survey because the receiver did not know about the deadline?
No. Lack of knowledge was not beyond the taxpayer's control, and the alternative 90-day extension period had expired, so the claimed credit became due.
Were a collective garden's exchanges of medical marijuana for member payments taxable retail sales or exempt donations, prescription drugs, or botanical medicines?
They were taxable retail sales. Payments exchanged for marijuana were consideration, not gratuitous donations. Medical authorizations were not prescriptions, and Schedule I marijuana was not a…
Were medical procedure kits exempt from Washington sales or use tax when they included some exempt drugs or drug-delivery supplies?
No. Taxable components exceeded 50% of each kit's component price. Filter needles and introducers did not themselves deliver drugs into the body, and separately purchased dressing supplies could not…
Were weekly dog-waste pickup services limited to the surface of residential yards subject to Washington retail sales tax?
No. Removing dog waste only from yard surfaces was neither cleaning a building or tangible personal property nor landscape maintenance. The receipts were subject to service B&O tax, not retailing…
Should Washington value asphalt transferred from a manufacturing division to a road-construction division by calculated cost or comparable external sales?
Comparable external sales. Similar quantity was evaluated job by job, not by annual customer volume; because comparable sales existed, the Department should not substitute calculated production cost.
Do contracts allowing a cable company to attach and maintain equipment in specified spaces on publicly owned utility poles create taxable Washington leasehold interests?
Yes. The agreements gave the company defined pole space for more than 30 days, continuing access to operate and maintain its equipment, and identifiable dominion and control. Restrictions and the…
Did inheriting part of a deceased parent's 50% interest in a real-estate-owning LLC trigger Washington REET when the heir's ownership rose above 50%?
No. Although the heir acquired a controlling interest, the LLC interest passed through the estate without consideration and was excluded as a transfer by devise or inheritance.
Could a Washington business overturn estimated cash sales with late-produced handwritten summaries and unsupported claims that some bank deposits were personal funds?
No. The electronic records were admittedly inaccurate, and the handwritten summaries contained negative cash sales on as many as 171 days, lacked source documents, and were not produced during the…
Could a proxy-voting provider deduct separately stated postage from Washington B&O and retail sales tax when clients supplied or directed the shareholder mailing lists?
Yes. New evidence showed the clients supplied the eligible-shareholder lists and directed delivery. The printed proxy materials therefore met the statutory direct-mail definition, and separately…
Did forgiving a family loan make a quitclaim transfer of rental property subject to Washington REET, and could good-faith reliance on an exemption waive penalties and interest?
Yes to REET and no to waiver. The borrowers were personally liable for the loan, and debt relief was consideration; misunderstanding the exemption did not justify relief.
Were turnkey mailbox-store development services taxable retail construction when the developer supervised and supplied labor for fixture installation and buildout?
Yes. Buildout supervision and labor were directly related to construction, and the developer was contractually responsible for performance. A reasonable reporting position did not waive the 5% penalty.
Are monthly management fees and corporate-service charges between separately organized affiliated companies subject to Washington service B&O tax?
Yes. Each separately organized affiliate is a distinct person for Washington tax purposes. Payments for corporate and financial services are gross income even between related companies, and…
Could a technology company use its Washington high-tech sales and use tax deferral for equipment at an unlisted location or for tenant improvements omitted from its application?
No. The approved application covered machinery and equipment at one specified site; it did not cover another location or unlisted tenant improvements.
Were a collective garden's medical-cannabis transfers for money taxable sales or exempt prescription drugs or naturopathic botanical medicine?
They were taxable sales. Contemporaneous records of unpaid visits showed payment was expected, not gratuitous. A medical-cannabis authorization was expressly not a prescription, and Schedule I…
Did an out-of-state bakery have Washington B&O nexus through an independent commissioned sales representative, and were common-carrier deliveries sourced to Washington?
Yes. The representative generated and negotiated Washington sales, and customers received the goods in Washington despite title passing at the out-of-state bakery.
Was a former spouse's quitclaim of a 50% home interest exempt from Washington REET when the other spouse refinanced and relieved the grantor of mortgage debt?
No. The transfer ended the tenancy in common, was not a court-ordered partition, and supplied taxable consideration by relieving the grantor of mortgage debt.
Were a medical-marijuana management company's transfers for member payments exempt from Washington sales tax as donations, prescription drugs, or botanical medicines?
No. It made taxable retail sales as principal or seller-agent, the payments were not donations, and marijuana met neither medical exemption during the periods at issue.
Did one LLC member's acquisition of the other two members' one-third interests trigger Washington REET on only the transferred 67%, or on all LLC real property?
It triggered REET on the full value of the LLC's Washington real property because one person acquired a controlling interest within 12 months.
Was a bare water-treatment system rented to a contractor for a public-road project exempt from Washington retail sales tax?
No. The contractor was the consumer of equipment rented for the public-road work, so the rental company had to collect retail sales tax on the charges.
Could a small timber harvester deduct 50% of gross receipts for harvesting and marketing costs supported mainly by handwritten records and an affiliated logger?
No. Without reliable documented costs or an arm's-length transaction, Washington applied the rule's standard 35% deduction rather than the claimed 50%.
During the 2012-2014 audit period, were a medical-marijuana operator's sales taxable if it claimed to act only as a collective garden's manager?
Yes. An agent making the transfers was still a seller, and the products did not qualify for the prescription-drug or naturopathic botanical-medicine exemptions.
For 2012-2014, were a Washington medical-marijuana collective garden's transfers taxable retail sales, and did written medical authorization create a prescription-drug exemption?
Yes, the compensated transfers were taxable business sales; no, medical authorization was not a prescription. With no sales records, Washington could estimate B&O and retail sales tax from industry data.
Was a 100% stock sale of a supermarket company subject to Washington REET because the company owned leasehold improvements classified as personal property on county tax rolls?
Yes. Improvements constructed on leased land are real property for REET when the lessee owns them and the agreements do not require removal. County property-tax classification did not control the…
Did an out-of-state software seller have Washington physical-presence nexus through an authorized reseller that generated no sales?
Yes. The reseller was marketed as local support and agreed to represent the seller and develop customer relationships, which helped maintain its Washington market.
Could a nonprofit avoid Washington retail sales tax by calling money received when it transferred marijuana to customers 'donations'?
No. Customers exchanged money for marijuana, so taxable sales occurred; inadequate records also left the nonprofit liable for sales tax on all assessed receipts.
Was a tire seller excused from Washington's tire fee after allegedly receiving oral Department advice that the fee had expired?
No. Sellers were personally liable for uncollected tire fees, and the Department could not waive the assessment based on undocumented oral advice or lack of individual notice.
Could a holding company exclude subsidiary payroll receipts from Washington B&O tax as reimbursements when it served as the employer of record and captive paymaster?
No. The company did not prove that it had only agent liability for the employer obligations, so the payroll receipts remained taxable gross income under the service classification.
Does standing-seam metal roofing qualify for Washington's solar-energy machinery and equipment sales-tax exemption because it supports rooftop solar panels?
No. The homeowner did not prove that the roof was specially designed, integral, and necessary to electricity generation rather than an ordinary building fixture supporting the panels.
Was towing adrift but undamaged recreational vessels maritime salvage taxed under service B&O rather than Washington public utility tax?
No. The records described towing and did not prove marine peril or the other salvage elements, so the activity was a tugboat business subject to public utility tax.
Could a telecommunications supplier reduce Washington wholesaling B&O income for claimed out-of-state sales and customer discounts without transaction-level records?
No. The supplier did not substantiate additional out-of-state sales or the amount of order-level discounts, and aggregate account credits were not price reductions known at the time of particular sales.
Did a Washington retailer substantiate nonresident sales-tax exemptions by recording buyer signatures, sale amounts, and out-of-state license numbers but not expirations or addresses?
No. The statutory method required ID expiration dates, while the streamlined method required additional data including purchaser address and business type. Interest also could not be waived.
Could a singles club deduct initiation fees and monthly dues when members received planned events, admission rights, and negotiated group rates?
No. Members paid for marketable event-planning and admission services, not merely the privilege of membership, so none of the charges were bona fide deductible dues.
Could a manufacturer satisfy a community-empowerment-zone tax deferral by using another company's workers, or keep a prorated deferral for one employee it hired?
No. Independent workers were not employees hired by the applicant, and failure to create all required positions made all deferred tax due without proration.
Did a contractor owe Washington's evasion penalty after collecting sales tax, using it for payroll, and changing accounting records to show wholesale sales?
Yes. Collecting tax proved the contractor knew it was due, and relabeling the tax as material costs or changing customers to hide retail sales showed intentional evasion. The penalty was removed…
Were a defunct computer company's president and treasurer personally liable for invoice charges labeled sales tax, and could they reopen the company's final assessment?
Yes to liability and no to reopening. Both controlled tax reporting or payment, the collected charges were trust funds, and the corporation had let its assessment become final.
Could a law firm exclude reimbursements of employee compensation and operating costs from Washington service B&O tax when it provided legal services to its parent?
No. The firm was the employer of record, provided the legal services, and had liability beyond a mere agent, so all cost reimbursements were taxable gross income.
Was a new foundation-repair contractor liable as a successor when it continued the predecessor's operations but did not receive a terminated dealer agreement?
Yes. It acquired most valuable intangibles—including personnel, contact information, reputation, goodwill, and testimonials—and was liable for final estimated taxes too.
Could a small business obtain a temporary waiver from Washington's electronic return and payment requirements because its computer no longer worked reliably?
Yes. Malfunctioning equipment, the burden of replacement, and hours of inefficient assisted filing established statutory good cause for a temporary waiver.
Were a private contractor's federal wildfire-suppression receipts wholesale sales or equipment rentals rather than service B&O income?
No. The true object was trained firefighting and fire suppression, an activity not otherwise classified and therefore taxable under service and other activities B&O tax.
Could a motel obtain a refund of interest and a late-payment penalty because it expected an audit assessment by mail instead of through its secure online tax account?
No. Electronic delivery followed the taxpayer's account agreement, and failing to review the secure account was not a circumstance beyond its control or a statutory basis to cancel interest.
Could a prime contractor exclude owner repayments of building permits, hookups, and impact fees from Washington retail sales and B&O tax as reimbursements?
No. The contractor agreed to provide the construction services, applied for and signed the permit, and was contractually and legally liable for the charges. Because the owner was not alone liable…
Where did an ecommerce payment processor's customers receive the benefit for Washington B&O apportionment: merchant billing addresses or buyer locations?
Buyer locations controlled because merchants completed online sales where purchasers received authorization; lower-tier billing addresses could not be used.
How did Washington classify and source an out-of-state ATM network processor's card-service and transaction-processing fees?
The fees were service income, not royalties, because membership primarily bought access to the processor's authorization, clearing, and settlement system rather than intangible-property rights.…
Were bagged chips taxable at sandwich shops whose prepared-food sales exceeded 75% of total food sales?
Yes. With utensils available and more than 75% prepared-food sales, Washington treated all food sales—including separately sold bagged chips—as prepared food.
Did imported vehicles remain exempt from Washington wholesaling B&O tax when accessories were added after unloading at a U.S. port?
No. Adding or installing port options served a business purpose rather than a transportation necessity, so import transportation ended before delivery and the Washington vehicle sales were taxable.
Did replica silver bullets qualify for Washington's precious-metal bullion tax exclusion even though they were shaped like ammunition?
Yes. They were smelted silver priced from spot value plus ordinary bullion premiums, could not be fired, and their value did not depend on the bullet form.
Did Washington's former biofuel deduction or a 2006 letter ruling protect separate renewable identification number sales and equipment sales from tax?
No. Separately sold RIN credits were taxable intangible-property income, the letter ruling addressed only biodiesel fuel, and the taxpayer's unapproved fiscal year did not shorten the calendar-year…
Could Washington estimate forest excise tax when a timberland owner's receipts showed much less harvested timber than field inspections and aerial photos?
Yes. The owner did not provide suitable records, and the Department reasonably relied on repeated field observations, aerial photos, and stump measurements to estimate the harvest.
Were mandatory online-library, science-lab, and nursing-program fees charged by an accredited online university taxable retail sales?
No to the student charges: they were excluded online education or tuition fees. But the university could owe use tax on untaxed digital products, uniforms, and lab kits it consumed.
Did retail sales tax stop after a trucking company's related-party lease payments exceeded equipment cost, and did port-to-Washington hauls qualify as interstate transportation?
No. The parties kept title with the lessors and treated the arrangements as true operating leases, so every payment remained taxable. Separate port pickup documents without an original through bill…
Where is a mutual-fund manager's service income attributed for Washington B&O tax when its only direct customer is an out-of-state financial company?
To the locations of the individual fund investors who ultimately receive the investment-management benefit, not merely the billing address of the out-of-state customer. The Department could estimate…
Could Washington estimate a restaurant's cash sales when its records showed only 2.66% of sales were paid in cash?
Yes. The unusually low cash percentage and incomplete records supported an estimate, and the Department reasonably used a 20% cash-sales rate that was below restaurant industry averages.
Did Washington's August 1, 2015 delinquent-penalty increase apply to older tax liabilities that were still unpaid on that date?
Yes. The outstanding liabilities automatically took the new 29% maximum rate, and timely-history, cooperation, or misunderstanding did not establish a waiver.
Could a sightseeing operator replace Washington's vessel value with an appraisal based mainly on the vessel's later selling price?
No. Audit reasonably estimated the earlier fair market value using depreciation and the result closely matched the operator's own book value, while the appraisal lacked comparable sales.
Could a builder avoid Washington's reseller-permit misuse and underpayment penalties because it did not know speculative-building purchases were taxable?
No. Speculative-building materials were consumed rather than resold, ignorance did not permit waiver, and a family illness did not explain three years of incorrect reporting.
Did an out-of-state gluten-free bread seller create Washington nexus by using an independent Washington broker to sell to distributors?
Yes. The broker's in-state sales activity was significantly associated with maintaining the seller's Washington market, creating nexus for wholesaling B&O and litter tax.
