Could a mental-health group exclude insurer payments it collected and passed to independently practicing member clinicians from its Washington B&O gross income?

Yes. Patients owed the clinicians, the group did not provide the care, and the contracts and disclosures made it a bona fide collection agent for the clinicians.

2021-01-20

Were point-of-banking debit-card fees charged during cannabis purchases part of the retail selling price for Washington sales tax and retailing B&O tax?

Yes. The processor's fee was a seller expense paid from the transaction's gross proceeds; only the estimated $4 fee amount was remanded for possible correction.

2021-01-12

Could an advertising agency exclude client-funded media costs as reimbursements and avoid an evasion penalty after collecting but not remitting retail sales tax?

No. Vendor contracts made the agency liable for client obligations, and years of collected sales tax that was reported incorrectly but never remitted established evasion.

2021-01-07

Could Washington reduce a B&O tax refund with use-tax liabilities from the same years even though those liabilities could no longer be issued as a separate assessment?

Yes. Refund offsets are not limited to the same tax category, and Rule 229 allows new information to reduce a refund even when the offset could not be separately assessed.

2020-12-21

Did a construction company's repeated underreporting and unsupported deductions justify Washington's evasion and payment penalties despite the owner's claimed lack of tax knowledge?

Yes. The reporting pattern, collected tax, and repeated Department education proved knowing evasion; lack of knowledge did not support a waiver.

2020-12-17

Could a Washington resident avoid use tax on personally titled out-of-state vehicles and boats by calling them inventory of his wholly owned dealership?

No. Personal title and Washington use made him the taxable owner; he proved no vehicle, watercraft, trade-in, valuation, penalty, or interest relief.

2020-12-16

Did an out-of-state recycler that made aluminum ingots qualify for Washington's aluminum-smelter B&O rate, and did its Washington nexus end after physical-presence trailing nexus expired?

No. It processed scrap rather than alumina and was not a direct-service industrial customer; its Washington receipts also exceeded the economic-nexus thresholds.

2020-12-15

Did a software developer owe Washington's reseller-permit misuse penalty when vendors failed to tax purchases that qualified for neither resale nor its high-technology deferral?

Yes. The buyer did not prove vendors relied only on the deferral certificate rather than its verified reseller permit, and it failed to correct the untaxed retail purchases.

2020-12-09

Could pharmacy benefit managers exempt affiliate payments as insurance income, exclude network-pharmacy claim funding as reimbursements, and report mail-order drug sales under service B&O tax?

They lost the insurance and reimbursement claims, but won retailing B&O treatment for separately priced mail-order and specialty prescription-drug sales.

2020-12-07

Did fuel tax paid upstream excuse sales or use tax on off-highway airport fuel, and could equipment-rental or refueling charges avoid retail tax?

No. Off-highway fuel sales and self-use remained taxable, rentals were retail sales, and refueling needed to complete a fuel sale was part of the taxable selling price.

2020-12-03

Did a Washington buyer constructively receive custom valves at the seller's out-of-state plant when the contract provided final acceptance and title passage there?

No. Contract terms did not show an affirmative exercise of dominion and control outside Washington. The buyer received the valves when the common carrier delivered them in Washington.

2020-11-20

Did a gym owe retail sales tax on fees a separate personal-training business paid to use the gym for classes?

Yes. The fees paid for use of the gym and related amenities, and the contract expressly said the businesses were not partners or joint venturers.

2020-11-04

Did Washington REET have to use a contaminated gas station's county-assessed value when unrelated parties negotiated a lower sale price?

No. The arm's-length contract price was supported by contamination evidence and appraisals, but REET applied to the full agreed price because an uninitialed allocation on the affidavit was invalid.

2020-10-29

Was a court-approved real-property sale by a general receiver exempt from Washington REET as a foreclosure or execution-of-judgment transfer?

No. The receiver completed a negotiated receivership sale under chapter 7.60 RCW, not a sheriff's foreclosure sale or execution under chapter 6.17 RCW, so REET applied.

2020-10-20

Could a personal-training business recover sales tax it mistakenly collected and remitted before first refunding the clients who paid it?

No. Collected sales tax belonged to the clients and was held in trust. The business had to refund them and document those repayments before seeking a corresponding Department refund.

2020-10-19

Were separately charged RV damage fees taxable income, and if so, were they retail rental receipts or service B&O income?

The fees were taxable gross income because they arose from the rental business, but optional separately stated damage charges were service B&O income, not retail rental receipts.

2020-10-12

Could a seller reduce its uncollected sales-tax liability by the renewable-energy refund its customer could have claimed after paying the tax?

No. The former exemption was a purchaser-only remittance: the buyer first had to pay the full tax, and the seller remained liable for tax it failed to collect.

2020-09-15

Can a Washington vehicle dealer preserve the sales-tax exemption for sales to nonresidents by obtaining affidavits and proof of out-of-state registration long after each sale?

No. The dealer had to retain the required identification, residence evidence, buyer affidavit, and seller certification when the vehicles were sold. Later proof of nonresidency did not cure the…

2020-09-08

Were large paper-making machines fixtures included in the real-property value for Washington REET on a controlling-interest transfer?

Yes. The machines were sunk into and bolted through the mill floors, integrated with decades of paper production, and objectively intended as permanent industrial fixtures.

2020-09-02

Were Washington parkour classes taxable as physical-fitness services before 2016 and as classes at an athletic or fitness facility after 2015?

Yes. The pre-2016 classes primarily developed fitness rather than delivering a documented instructional curriculum, and the taxpayer's later parkour gym was an athletic or fitness facility.

2020-08-21

Did Washington's 2018 REET exception for transfers of qualified low-income housing apply retroactively to a 2017 controlling-interest transfer?

Yes. The statute expressly covered transfers before its effective date, so a later additional assessment was canceled; however, it barred refunds of REET already paid before July 1, 2018.

2020-08-06

Were a licensed contractor's consulting and owner-representation charges taxable as construction services when invoices showed material purchases and contractor coordination?

Yes. The invoices showed work normally performed by a contractor responsible for construction, and the taxpayer supplied no contracts proving it acted only as a consultant.

2020-07-20

Were short rides on old-fashioned passenger trains taxable sightseeing day trips when customers came to experience the trains rather than scenic views outside?

Yes. The heritage trains and cultural experience were themselves sights, and Washington's retail classification does not require scenic views outside the vehicle.

2020-07-16

Could a Washington manufacturer obtain cancellation of audit interest based on COVID-19 hardship?

Only in part. The COVID-19 proclamation waived interest accruing on or after February 29, 2020, but the taxpayer proved no statutory basis to cancel earlier interest.

2020-07-14

Were a portrait photographer's session fees taxable retail sales when the contract included edited images delivered through an online gallery?

Yes. The electronically delivered photographs were digital goods, and the contract required their delivery; calling the work photography for hire did not remove the retail sale.

2020-06-26

Could a restaurant overturn an estimated sales-tax assessment when its point-of-sale records showed missing checks, extensive voids, and implausibly low cash sales?

No. The restaurant's incomplete and internally inconsistent records justified an estimate, and it did not show that the Department's 31% cost-of-goods cap was unreasonable.

2020-06-23

Did an out-of-state insurance-claims company have Washington nexus and owe retail sales tax and retailing B&O tax on water-mitigation work performed by local contractors?

Yes. Its Washington contractor network created substantial nexus, the water-mitigation work was a taxable retail service, and tax applied to the full amount billed to insurers—not merely the…

2020-06-19

Where are affiliate credit-card, database, and administrative service receipts apportioned when records do not support separating the bundled services?

They were apportioned together to cardholders' billing addresses because the services' true object was enabling affiliates to extend and service credit in those markets.

2020-06-16

Could a business receive Washington clean-alternative-fuel vehicle tax credits after submitting its final vehicle documents beyond the statutory deadline?

No. The governing statute required final documentation within 15 days of receiving the vehicles and required the Department to deny applications that missed that deadline.

2020-06-10

Were integrated online-banking and automated phone services excluded data processing, or taxable digital automated services under Washington law?

They were taxable digital automated services because excluded functions were only components of broader integrated products, and the tax did not violate the Internet Tax Freedom Act.

2020-06-04

Must a retirement community collect Washington sales tax on meals for independent residents and short-term guest rooms for residents' family members?

Yes. Independent-living meal sales and family guest-room rentals were taxable retail activities even though the same campus also provided assisted living.

2020-06-02

Was daily sweeping of sawdust and debris from a lumber mill floor nontaxable janitorial service despite the industrial setting and use of lifts for access?

Yes. Daily broom-and-blower floor cleaning was ordinary work regularly performed by commercial janitors, not specialized building or machinery cleaning subject to retail sales tax.

2020-05-08

Did a Washington data center satisfy the employment conditions required to keep its sales-and-use-tax exemption certificate benefits?

No. The tenant needed six new family-wage positions. An employee whose position existed before the certificate did not count; another employee on disability did, but that left only five qualifying…

2020-05-07

Were wholesale goods sourced to Washington when customer-selected common carriers picked them up FOB at out-of-state warehouses and delivered them to Washington customers?

Yes. Carrier possession was not customer receipt. The buyers first took physical possession in Washington, so the sales counted toward Washington economic nexus despite FOB and freight terms.

2020-05-05

Is a partnership's transfer of all its real property to a partner who owns only 49% exempt from Washington REET as a mere change in identity?

Only the partner's existing 49% share was a mere change in form; the disproportionate 51% increase in beneficial ownership remained subject to REET.

2020-05-01

Could an LLC claim Washington's veterans employer B&O credit for a paid veteran who was publicly identified and filed state records as the LLC's owner and governor?

No. The veteran functioned as an owner and governor rather than an employee, and the LLC also lacked records proving the credit's unemployment and qualifying-period requirements.

2020-04-28

May Washington estimate a contractor's tax and treat claimed wholesale jobs as retail when its accounting records, invoices, and reseller documentation are incomplete?

Yes. The Department reasonably used available records to estimate tax, and undocumented claimed wholesale construction sales remained retail.

2020-04-03

Does a port district owe leasehold excise tax after buying a privately owned building and assuming tenant leases that do not mention the tax?

Yes. The private tenants' possession becomes a taxable leasehold in public property, and the port's assumed-lessor status makes it liable even if the old leases omit tax collection.

2020-04-02

For Washington REET, does a distressed property's negotiated sale price control when the seller is pressured to sell quickly and the price is far below county value?

No. The pressured, unmarketed sale was a nominal or panic price rather than true and fair value, so the Department properly used the county tax-roll value.

2020-03-25

Is a court-approved settlement transferring a 50% interest in a real-estate-owning LLC exempt from REET as an execution of a judgment?

No. The transfer arose from a negotiated settlement, not a writ of execution and sheriff's sale; debt relief was consideration and controlling-interest REET applied.

2020-03-24

Can a Washington resident avoid travel-trailer use tax by buying out of state, bringing it to Washington, and later selling it to an out-of-state LLC?

No. Use tax attached when the resident first brought and controlled the trailer in Washington, and private website advice did not justify waiving late-payment penalties.

2020-03-13

Did injection molds qualify for Washington's manufacturing M&E exemption when a vendor used them to make plastic housings from the vendor's materials?

No. The purchaser was the customer, not the manufacturer, of the plastic housings because the vendor supplied the materials and production work.

2020-03-03

For REET on a 50% LLC-interest transfer, may a negotiated discount for restrictions on selling the LLC reduce the value of the real estate the LLC owns?

No. REET was based on the real property's true and fair value, not the discounted LLC-interest price; without a property appraisal, county tax-roll values controlled.

2020-02-28

Can a taxpayer avoid late-payment penalties by filing timely zero returns and later reporting Washington apportionable income only through annual reconciliations?

No. Penalties applied because the original zero returns omitted income the taxpayer could calculate, and uncorrected unpaid returns also defeated the 24-month waiver.

2020-02-28

Could a bank deduct interest from mortgage-backed securities and Ginnie Mae investments without documents proving rights in the mortgages or a direct federal obligation?

No. The bank supplied no participation certificates or investment documents proving enforceable mortgage rights or that the United States was the primary obligor.

2020-02-19

Did a remotely operated Washington LLC have physical-presence nexus through its registered agent, bank account, mailboxes, and in-state answering service?

Yes. The owner's registered-agent presence and the LLC's Washington property and customer-support activities were more than enough to establish nexus.

2020-02-14

Does a cruise line's preferential tour-operator B&O classification cover separately sold sightseeing excursions lasting less than 24 hours?

No. The overnight cruises qualified for tour-operator B&O treatment, but optional day excursions were retail sightseeing trips subject to retailing B&O and sales tax.

2020-02-12

Is data-center colocation income exempt real-estate rent when customers use locked cages, or taxable service income when the provider retains control over access and use?

It was taxable service B&O income because customers received only a limited license to use cage space, not exclusive possession and control of leased real estate.

2020-02-06

Could a Washington business remain a quarterly excise-tax filer after exceeding the monthly-filing liability threshold because monthly reporting cost more?

No. The business exceeded the historical $4,800 annual-tax threshold every full year. Higher compliance costs and lower margins were ordinary burdens of monthly filing, not a specific situation…

2020-02-06

Can a Washington sailboat buyer use the actual purchase price rather than a higher guide value when an independent appraisal confirms the boat's poor condition?

Yes. The actual purchase price represented the boat's true value because an independent appraisal and other evidence supported a similar distressed-condition value.

2020-01-23

Are an online retailer's prescription pet-medication sales exempt from Washington sales tax, and may the Department estimate local tax when destination records are missing?

No exemption applied to stand-alone pet-medication sales, and the Department could reasonably estimate local sales tax because the retailer lacked shipment-destination records.

2020-01-15

Are residential hot-tub cleaning and chemical-maintenance services nontaxable janitorial services or taxable specialized cleaning in Washington?

They are taxable specialized cleaning services, not janitorial services, so the charges are subject to retail sales tax and retailing B&O tax.

2020-01-13

Can a single-member Washington LLC claim the veterans hiring B&O-tax credit for payments to its veteran owner when it has no employees or employment-tax reporting?

No. The sole owner was not the LLC's employee under the employment factors, so the owner was not a qualified employee for the veterans hiring B&O-tax credit.

2020-01-09

Does a Washington cigarette retailer owe tax and penalties after returning unstamped packs for proper stamping, and does loose tobacco with tubes count as roll-your-own cigarettes?

The returned packs were not taxed twice, but possessing them still triggered a penalty; loose tobacco and tubes were not roll-your-own cigarettes without a commercial machine or produced cigarettes.

2019-11-26

Can a parking operator recover sales tax collected on tax-exempt long-term reserved spaces without first refunding the customer, and can it recover the related B&O tax?

It could recover B&O tax on long-term reserved-space rental income, but not customer-paid sales tax unless it first refunded that tax to the customer.

2019-11-26

What Washington tax applies when an auto-repair business buys items with a reseller permit, consumes some itself, and uses parts in fully discounted promotional services?

Deferred sales tax applied to self-consumed purchases, and use tax applied to parts used in free promotional services at the business's vendor cost; the reseller-permit penalty remained.

2019-11-15

Did a convenience store owe cigarette tax and penalties when its distributor supplied packs bearing another state's stamps?

Yes. Possession triggered tax and a $10-per-pack penalty, and the store's failure to inspect inventory was not an external circumstance supporting waiver.

2019-11-05

Did cleanup of radioactive mine waste qualify for Washington's preferential federal radioactive-waste cleanup B&O classification?

No. The mine waste was not shown to be a by-product of weapons production or nuclear research and development, as the classification requires.

2019-09-24

Were apartment turnover cleanouts nontaxable janitorial services when they included heavier maintenance and restoration work?

No. The sporadic turnover work was a special cleanup needed to restore units for rent, making the charges subject to retail sales tax and retailing B&O tax.

2019-09-17

Was a seller entitled to a Washington REET refund on the initial deed to a Section 1031 exchange facilitator?

No. The initial transfer to the facilitator was taxable, and the rule's exemption applies only to a facilitator's later transfer completing the exchange.
