Could a chiropractic corporation obtain penalty and interest waivers after a payment-processor cyberattack disrupted its cash flow and it allegedly received oral advice to await a payment plan?
No. Washington treated the processor outage's effect as financial hardship, not a qualifying circumstance beyond the clinic's control, and the law did not allow relief based on recalled oral advice.
Who may claim children for Washington's Working Families Tax Credit when both parents claim the same children for the same year?
The other parent could claim the children because they lived with that parent longer during 2022. Without qualifying children, the applicant exceeded the applicable income limit and had to repay the…
Could Washington audit an active-nonreporting construction business and estimate tax when the business produced no adequate records?
Yes. Active-nonreporting status did not bar an audit, and after the contractor refused to provide required records, the Department reasonably estimated one taxable construction project per year.
Could an aerospace manufacturer avoid loss of Washington tax incentives after filing three annual performance reports late because of ownership changes, records access, personnel turnover, or COVID-19 relief?
Mostly no. Those facts did not justify extensions, and the COVID-19 proclamation did not suspend these report deadlines. But the Department could disallow only 35%, not 50%, for 2019 and 2020…
Was REET due when parents who joined title only to help their daughter obtain a mortgage later quitclaimed their interest to her without consideration?
No. The parents were added only as mortgage co-signers, made no property payments, received no consideration, and quitclaimed their interest after the daughter refinanced alone.
Could a beverage distributor exclude affiliate service payments from B&O-tax gross income by characterizing the arrangement as a joint venture?
No. Payments from related entities reimbursing the distributor for warehousing, delivery, payroll, and other services were its gross income. Calling the arrangement a joint venture created no B&O…
Did a construction company rebut Washington's evasion penalty for sales tax it collected but did not remit?
No. Years of charging customers sales tax while largely reporting wholesale activity and not remitting the collected tax established evasion; new evidence of bookkeeping inexperience did not rebut it.
Did Washington's July 2022 B&O exemption for custom farming and related farm services apply retroactively to the 2021-to-June-2022 gap?
No. RCW 82.04.758 took effect July 1, 2022, contained no retroactive language, created a substantive exemption, and could not cover the earlier gap period.
Was REET due when an LLC quitclaimed property to carry out a divorce settlement decree without new consideration?
No. The sole owner's LLC merely completed the divorce decree's required transfer without new consideration, after an earlier transfer to the LLC left beneficial ownership unchanged.
What records must a Washington hotel keep to treat a federal employee's government-card lodging as sales-tax exempt?
The hotel must prove the federal government—not the employee—was liable for payment, including the card type and required account digits. Incomplete records did not support the remaining refund.
Can an aerospace company claim Washington's product-development B&O credit using estimated federal R&D expenditures instead of project-level actual records?
No. The credit required actual qualified aerospace expenditures documented in ordinary business records; estimates derived for federal tax purposes did not prove the Washington credit.
Can a cannabis retailer claim Washington's qualifying-patient exemption without preserving the recognition-card number used for each sale?
No. The retailers failed to keep recognition-card copies and the card number tied to each exempt sale; later customer numbers could not prove earlier transactions qualified.
Does a new boat qualify for Washington's electric-vessel sales-tax exemption when the buyer adds the electric motor after purchase?
No. The vessel exemption required a new boat already equipped with a qualifying electric propulsion system when sold; adding a separately exempt motor later did not exempt the boat.
Are dental insurance premiums exempt from Washington B&O tax, and can outside-agency guidance support penalty relief?
The dental premiums were subject to service B&O tax because no Washington premium tax applied. Dentist payments were separate transactions, and OIC guidance did not support waiving penalties or interest.
Are digital-service customization charges and related travel reimbursements subject to Washington retail sales tax?
Yes. Implementation work sold only with digital automated services was part of the taxable retail sale, and related travel reimbursements were included in the taxable sales price.
Can an aircraft buyer obtain a Washington use-tax penalty waiver because an accountant failed to complete the payment process?
No. A contracted accountant's failure was not beyond the taxpayer's control, and later efforts to pay began after the maximum delinquent penalty had accrued.
Can a Washington taxpayer obtain a penalty waiver by recalling oral Department advice or relying on a CPA's nexus advice?
No. Recalled oral advice is not written Department guidance, and a contracted tax advisor's mistake is not a circumstance beyond the taxpayer's control.
Can a Washington funeral home deduct customer reimbursements paid to a commonly owned affiliate from its B&O-tax measure?
No. The funeral-home reimbursement deduction excludes goods or services supplied by an affiliated or associated person, and the same owner controlled both companies.
Did grantor trusts formed by a bank subsidiary qualify for Washington's B&O exemption for securitization entities formed by a bank holding company?
No. The trusts were formed by a corporation that was a bank subsidiary, but they did not prove that their direct creator was itself a bank holding company as RCW 82.04.650 requires.
Was the arm's-length sale price of an aged rural church property too low to use as the REET measure merely because it was below the county assessment?
No. The property's poor condition, limited possible uses, small local market, and broker-led open-market sale supported the negotiated price. The Department did not rebut the presumption that it was…
Could a Washington retailer exclude register shortages and overages from retail sales tax and retailing B&O tax because its books used accrual accounting and monthly net reconciliations?
No. Shortages could not reduce recorded sales and overages were presumed unrecorded sales. The retailer's monthly net figures did not rebut the daily point-of-sale records or the audit projection.
When is a data-center colocation contract an exempt real-estate lease rather than a taxable license to use Washington property?
Exclusive possession and control were decisive. Dedicated locked suites with quiet enjoyment were exempt leases, while shared rack space that the operator controlled and could relocate was a taxable…
Could a Washington medical-cannabis retailer claim sales-tax-exempt cardholder sales without keeping recognition-card copies and linking each exempt sale to a card number?
No. The retailer had to keep one copy of each valid recognition card and records tying the card number to each exempt sale for five years. Point-of-sale labels and cannabis-board entries alone did…
Did fees paid to a Washington television station by cable and satellite distributors qualify for the preferential broadcasting B&O rate?
No. The station licensed distributors to alter its signal by inserting their own advertising and retransmit it to customers. That income was royalties, not qualifying broadcast advertising, even for…
Was a transfer of 92.5% of an LLC that owned debt-encumbered Washington real estate partly exempt from REET as a gift of the equity?
No. Relief from the LLC's debt was consideration, so the controlling-interest transfer was not a gift. REET was measured by the full true and fair value of the LLC's Washington real estate, not just…
Could Washington replace an unrelated buyer's negotiated sale price with the higher county-assessed value when calculating REET on two properties sold together?
No. The open-market, arm's-length price was presumed to be true and fair value. A price equal to 79% of assessed value was not nominal, especially after the assessor had reduced the properties'…
Was local use tax on an aircraft bought outside Washington sourced to the low-tax county where it briefly landed first or to the city where it was regularly hangared and used?
It was sourced to the aircraft's regular home base. A brief, transitory landing in a lower-tax county was not the first taxable local use; the city where the owner hangared and flew the aircraft had…
Was an event-merchandise consignee acting as an agent, or was it the retail seller responsible for remitting collected Washington sales tax?
The consignee failed to prove agency and was the retail seller responsible for collected sales tax. Retail sales and card fees belonged under retailing B&O, while the evasion penalty survived only…
Could a used-car dealer claim larger Washington sales-tax and B&O bad-debt deductions by writing off each repossessed vehicle's entire unpaid loan balance?
No. The dealer had to subtract the repossessed vehicle's market value from the unpaid debt and keep records supporting that calculation. Its worksheets and repossession records did neither, so the…
Was a former spouse's later purchase under a right of first refusal exempt from Washington REET because the sale agreement was incorporated into the dissolution decree?
No. The decree changed the home's ownership form, but the former spouse's later voluntary exercise of a right of first refusal was a separate purchase rather than a court assignment of property, so…
May a digital advertising exchange report only its commission for Washington B&O tax by treating publisher payments as marketplace or pass-through amounts?
No. The exchange had to report all advertiser receipts as gross income from advertising services; publisher payments were nondeductible business costs, not marketplace-facilitator or qualifying…
Were monthly testing and chemical treatment of water circulating in a hotel's closed-loop HVAC system taxable retail services in Washington?
Yes. Water is tangible personal property, and the company did more than consult: it tested and chemically altered the HVAC water. Tax also applied to the separate testing materials.
Was a husband-and-wife transfer of jointly owned Washington real estate to an LLC owned solely by the husband exempt from REET as a family-entity transfer?
Yes. The LLC was wholly owned by the wife's spouse, so the family-entity rule exempted her transferred interest even though the transaction changed beneficial ownership. The couple's refund request…
Did an out-of-state online and wholesale seller have Washington nexus because local retailers accepted warranty repairs and company representatives visited them yearly?
Yes. Advertised in-state repair and warranty-return services and annual representative visits helped maintain the Washington market. A formal agency relationship was unnecessary.
Could a convenience store avoid Washington other-tobacco-products tax and a late-payment penalty because it misunderstood who owed the tax and paid one day late?
No. Buying untaxed tobacco from an unlicensed seller made the retailer the taxable distributor. Inexperience and a mistaken due date were not circumstances beyond its control.
How were recurring railcar lease payments sourced for Washington retail sales tax and retailing B&O tax when customers first received the cars outside the state?
Each payment was a separate sale. Sales tax used the first delivery location and then the customer's business address. Pre-July 2017 B&O tax instead used each railcar's primary location for later payments.
Were separately charged telephone support, training, and seminars for an electronic-signature platform taxable as part of a digital automated service?
Yes. Customers could buy those services only with the electronic-signature platform, so they were provided exclusively with a taxable digital automated service despite separate charges or human effort.
Could a construction company obtain B&O and use-tax refunds without complete source records showing its income and prior tax payment on installed government-project materials?
No. The installing contractor did not substantiate its income or prove that sales or use tax had already been paid, and the Department's 40% materials-cost estimate was reasonable.
Could related LLC members use their agreed price as the REET value for a 15.7% real-property interest without an appraisal or qualifying asset allocation?
No. Because the related-party price did not establish true and fair value and no appraisal or qualifying allocation was provided, the Department properly used 15.7% of the county tax-roll value.
Did an LLC's transfer of an apartment-building interest to a subsidiary owned by two members qualify as a mere-change or partner-distribution REET exclusion?
No. The records did not prove the members surrendered their entire interests before the transfer, so beneficial ownership changed. The subsidiary also was not a partner of the transferring LLC.
What timber-harvesting deduction applied when invoices mixed qualifying and nonqualifying work, and could the first-return delinquent penalty be waived?
The standard 35% deduction applied because costs could not be separated. The first-return penalty was waived because registration preceded harvesting, but interest remained.
May a pharmacy benefit manager exclude customer-funded pharmacy payments and manufacturer rebates from Washington B&O-tax gross income, and waive late reconciliation penalties?
No. Customer payments for pharmacy costs and manufacturer rebates were gross income, not qualifying pass-throughs or discounts, and misunderstanding the annual-reconciliation rules did not justify…
Did equipment used at a separate warehouse to inspect, de-clump, bottle, label, and package finished vitamins qualify for Washington's manufacturing M&E exemption?
No. Manufacturing had already occurred elsewhere. The warehouse changed the packaging, not the vitamins, and packaging and quality-control work at a separate nonmanufacturing site did not qualify.
Could Washington estimate a cash-based landscaping business's taxable sales from industry averages when the owner did not provide source records?
Yes. Missing invoices, checks, and complete bank records justified an estimate using averages for similar small landscaping businesses in the same region.
Can an EV buyer obtain a retail-sales-tax refund directly from Washington Revenue without the seller or buyer declaration required by Rule 229?
No. Although the used EV qualified for a partial exemption, the buyer had to seek a dealer refund or submit the required sworn declaration.
Does fabricating a replacement component for installation during a paid repair count as manufacturing for Washington's machinery-and-equipment exemption?
Yes. Delivery of the repaired equipment transferred the fabricated component for consideration, so it was manufactured for sale and qualifying machinery could be exempt.
Can a mixed wholesale-and-retail warehouse claim Washington's remittance without 200,000 square feet dedicated exclusively to wholesaling?
No. The qualifying area had to be dedicated exclusively to wholesaling, and the company could not identify 200,000 square feet used only for that activity.
Where are receipts from outsourced residential property-tax payment services attributed for Washington B&O tax?
To the location of each taxed property. Paying its property tax is directly related to real property, even though lenders hired and paid the service provider.
Must businesses that omitted apportionable income file annual reconciliations, and can late reconciliations avoid Washington delinquent-payment penalties?
Yes, they must reconcile by October 31 of the following year. Missing that deadline exposed the unpaid tax to mandatory delinquent penalties, with no waiver shown here.
Did a 2021 Toyota Prius Prime qualify for Washington's plug-in-hybrid use-tax exemption based on the owner's observed electric range?
No. The model's EPA electric-only range was 25 miles, it was not on DOL's qualifying list, and Revenue could not overrule DOL's model decision.
Did a distributor have Washington nexus through its parent retailer, remain separately taxable after merging into that parent, and substantiate disputed wholesale sales?
The parent retailer's Washington promotion and order-taking created pre-merger nexus, but post-merger internal transfers were not taxable because only one entity remained; unsupported wholesale…
Did oral custom-farming agreements qualify harvesting and cultivation services for the B&O exemption, and was farm equipment exempt from use tax?
The services qualified because oral agreements and customer evidence proved custom farming, but the equipment remained taxable because the exemption covered replacement parts, not machinery.
Where did customers receive the benefit of genealogical research, and did a good-faith tax position justify waiving penalties?
At the customers' residences, where they received increased knowledge of their family history. Good faith alone did not justify penalty relief.
When do audio-equipment rentals to Washington artistic or cultural organizations qualify for exemption, and can a completed exemption certificate protect the seller?
Bare audio-equipment rentals, including setup or takedown only, can qualify; rentals with an operator are services outside this exemption. A fully completed buyer certificate can still relieve the…
Was exchanging full ownership of separate jointly owned properties a REET-exempt partition or mere change in identity when each co-owner was relieved of debt?
No. Each whole property changed from 50/50 ownership to 100% ownership, so there was debt consideration but no physical partition and no unchanged pro rata interest.
Where did an out-of-state patent law firm's Washington clients receive the benefit of patent-procurement services, and did Department guidance justify penalty or interest relief?
At the clients' headquarters, where strategic patent decisions occurred. Most penalties stayed, but specific May-to-July 2019 written guidance required limited relief.
Were a Washington port's separately billed, no-markup charges for third-party utilities used by long-term tenants subject to PUT or B&O tax?
No. The utility charges were unrelated to the port's public-service activities and were normal lease expenses billed at cost, so they were outside PUT and exempt real-property rental income for B&O tax.
How did Washington classify and apportion a technology retailer's manufacturer rebate income, and what records were required to adjust estimates?
Washington treated supplier rebates as service-and-other-activities B&O income, upheld a sales-based receipts factor, and denied adjustments and waivers that lacked the required records or statutory…
Was a new franchise restaurant owner liable for its predecessor's Washington taxes after taking the same location, lease, equipment, and business operation?
Yes. Assuming the predecessor's lease debt and acquiring its tangible and intangible assets made the new operator a successor, even without a formal purchase agreement.
Was an aircraft-owning LLC's lease to a company led by the same founder a true lease that allowed the aircraft purchase to qualify as a resale?
Yes. The lessee paid fixed rent, controlled and operated the aircraft, gained no equity or purchase option, and had to return it. The owner did not control the lessee, so no use tax or…
