Could two restaurants disavow their own POS sales-tax and receipt records and deduct online voucher-provider commissions from taxable gross proceeds?

The withdrawn determination generally said no, but the current PDF partially reduced Taxpayer A's sales-tax assessment. Washington withdrew the decision effective July 25, 2022, so it is no longer…

2014-05-14

Did a Washington buyer receive bulk beverage goods in Washington when it directed an out-of-state packager to accept and repackage them?

No. The buyer exercised dominion and control through its out-of-state agent before the finished units later moved to Washington retailers.

2014-05-13

Could an internet research company revive old refunds through a net audit credit, alter an agreed block sample, assign panelist costs as representative services, or postpone substantiation?

No. Washington held that a net audit credit was not payment, sustained the block sample without complete records, treated panelist costs as formula costs, and denied claims lacking timely substantiation.

2014-05-09

Could a contractor retain collected sales tax, exempt nonprofit construction, claim an unsupported UBI credit, or avoid tax without a current reseller permit?

No. Collected tax had to be remitted, nonprofit status supplied no construction exemption, records did not support the credit, and the seller bore liability without a valid permit.

2014-05-09

Were spray, airbrush, or other sunless tanning services taxable retail sales even when the salon did not collect sales tax from customers?

Yes. Washington treated sunless tanning as a retail-taxable tanning salon service, so the provider owed retail sales tax and retailing B&O tax even though it had not collected the sales tax.

2014-05-07

Did a mother's transfer of her remaining mortgaged-home interest to her son qualify as a REET-free gift without records of their joint mortgage payments?

No. Joint debt liability alone did not prove the absence of consideration; requested bank records were needed to show both parties paid from a joint resource before and after transfer.

2014-04-29

Were goji juice products exempt food in Washington when the bottles called them liquid dietary supplements and displayed Supplement Facts panels?

No. The juices contained dietary ingredients, were ingested in liquid form, and carried compliant Supplement Facts panels, so they were taxable dietary supplements rather than exempt food.

2014-04-29

Did extinguishing an insolvent member's 50% LLC interest create a taxable REET controlling-interest transfer when the member avoided future capital contributions?

Yes. The other member acquired full control, relief from capital contributions was valuable consideration, and no cited REET exemption fit the transaction.

2014-04-18

When a health insurer and affiliates exchange services and settle only the net balance, is Washington B&O tax measured by net cash or the gross value received?

The gross value received. Services supplied by affiliates were noncash consideration—credits or property expressed in money—for the insurer's own services. Netting reciprocal charges did not create…

2014-04-09

Were mandatory shopping-mall promotional dues taxable service income, or were they rent derived from leasing real property?

They were rent, not taxable service income. Washington treated the mandatory, customary lease charges as amounts derived from renting mall space and removed the related B&O tax.

2014-04-03

Could a retailer keep sales tax mistakenly collected on pre-discount prices and exclude manufacturer-coupon reimbursements from the taxable selling price?

No. Washington required the retailer to remit all tax collected from customers and treated manufacturer-coupon reimbursements as part of the selling price, while true store-funded discounts reduced it.

2014-04-03

Did an out-of-state upholsterer owe Washington's 50 percent evasion penalty after collecting sales tax on 187 invoices without registering or remitting it?

Yes. Five years of separately stated and collected sales tax showed knowledge of the liability, and keeping it without a reasonable explanation proved willful nonpayment.

2014-04-01

Were a club's 18% large-party gratuities, remodel supervision charges, and mistakenly over-collected sales tax all taxable or payable to Washington?

Yes. The gratuities were not shown to be voluntary, the remodel contractor supervised taxable construction, and customer tax collections had to be remitted unless refunded.

2014-03-26

Could a hair salon exclude business-account deposits from Washington B&O income by saying they came from outside wages without documenting each deposit?

No. With only bank statements and federal returns, the Department could treat total business-account deposits as the best available gross-income estimate.

2014-03-25

Were domestic and foreign rare metal coins exempt monetized bullion even when collectors paid more than face value?

Yes. Metal coins used as legal exchange in the past, present, or future qualified as monetized bullion unless sold to be made into jewelry or art.

2014-03-25

Did an out-of-state service company retain Washington B&O nexus after its in-state sales representative stopped visiting in 2006?

Yes. The representative's solicitation created nexus, and the then-existing trailing-nexus rule continued the obligation through the 2007–2010 refund period.

2014-03-25

Could Washington assess more vehicle use tax when a buyer's books and federal depreciation schedules showed values above those accepted at licensing?

Yes. Licensing collected the tax as the Department's agent, but Revenue retained assessment authority and could review the appraisal and use the buyer's own records as value evidence.

2014-03-25

Was adding a partner to a home's title during a joint mortgage refinance exempt from Washington REET as a gift?

No. The partner assumed joint mortgage liability and began paying half the mortgage, providing debt relief and therefore consideration for the ownership interest.

2014-03-19

Did making compound semiconductor wafers only as an intermediate step qualify for the preferential B&O rate and the gases-and-chemicals tax exemption?

Only partly. Washington denied the preferential B&O rate because the intermediate wafers were not separately taxed products, but allowed the sales and use tax exemption for qualifying gases and…

2014-03-18

Were amounts a custom-yacht builder billed for subcontracted naval architecture and engineering separate service income, or part of the yacht's taxable manufacturing proceeds and selling price?

They were part of the yacht sale. The builder hired and paid the designers, then billed its customer for services necessary to produce the custom yacht. Those reimbursements were manufacturing gross…

2014-03-17

Could a Washington DISC apportion pre-June 2010 commission income outside the state based on its affiliate's foreign export sales?

No. The DISC performed no foreign sales activity and existed only to create a federal tax benefit; its sole business activity and place of business were in Washington.

2014-03-12

Could a bar treat listed beverage prices as including sales tax without receipts separately stating tax or reliable proof of visible tax-included notices?

No. Washington presumed the beverage prices excluded tax because the bar did not separately state it and failed to prove that menus or visible signs disclosed tax-included pricing during the audited sales.

2014-03-06

Could a corporation exclude affiliate payments for shared restaurant employees as payroll reimbursements when it reported and paid the employees under its own employer accounts?

No. It was the employer of record, used the employees to provide affiliate services, and did not prove that it had only agent liability for their payroll obligations.

2014-03-04

Could Washington estimate a grocery store's sales from bank deposits and purchase logs and impose a 50% evasion penalty when records were inadequate?

Yes. The store lacked reliable sales records, so the Department could estimate liability from available evidence, and substantial selective underreporting plus knowledge of the tax supported the…

2014-02-27

Did an out-of-state sportswear seller create Washington tax nexus by sending representatives to recurring trade shows without taking orders there?

Yes. Repeated visits to display products, meet potential buyers, discuss product models, and distribute catalogs were significantly associated with establishing and maintaining a Washington market.

2014-02-20

Did cutting raw logs into customer-specific higher-grade veneer blocks qualify as manufacturing for Washington's preferential timber-products B&O tax rate?

Yes under the general manufacturing definition. The process produced shorter logs of specific length, grade, quality, and greater usefulness; the unrelated use-tax challenge remained denied.

2014-02-18

Did a new contractor avoid Washington successor tax liability by claiming its owner purchased the predecessor's assets from the IRS?

No. The IRS liens remained, no regular lien-enforcement sale was proven, and the new company continued with virtually all tangible and intangible business assets.

2014-02-06

Did a nonprofit hospital owe Washington B&O tax when its self-funded employee health plan paid the hospital for employees' medical care?

Yes. Payments for hospital services were gross income even though funded from the hospital's assets, and billing 100 percent with no price reduction created no bona fide employee discount.

2014-01-31

Were admission and private-party fees for an indoor inflatable playground taxable amusement and recreation services in Washington?

Yes. Active play on inflatable structures was recreation, and the single party fee remained taxable because it bundled playground access with incidental hosting services.

2014-01-28

What value measured Washington REET when one member bought the other member's 50 percent interest in an LLC owning real estate?

The county property-tax value applied because the LLC supplied neither a fair-market appraisal nor a qualifying asset allocation establishing a different true and fair value.

2014-01-15

Was a residence transferred from an irrevocable personal-residence trust back to its grantor exempt from REET as a mere change in ownership form?

No. The grantor bought the residence from the trust with a promissory note, so valuable consideration supported a taxable sale and the transfer altered future beneficial interests.

2014-01-09

Could a beverage manufacturer treat rented shipping pallets as packing materials purchased for resale when the pallet vendor always retained ownership?

No. The manufacturer rented and used the pallets but never acquired title or the contractual right to sell them to customers. Because the transaction was a rental of tangible personal property to a…

2014-01-02

Were personalized strength and conditioning sessions for athletes taxable physical fitness services or nontaxable instruction in Washington?

They were taxable fitness services. The coach assessed workout needs and tailored exercise regimens to improve sports performance, strength, agility, conditioning, and health.

2013-12-31

Were foundation payments supporting a rural medical clinic deductible from Washington B&O tax as charitable contributions or donations?

No. The foundation paid under an agreement requiring the clinic to operate and manage a medical facility, so the funds compensated services and were not gratuitous gifts.

2013-12-31

Were virtual print fees paid by movie distributors to a digital-cinema equipment deployer Washington royalty income?

No. The fees financed and incentivized rapid digital-projector deployment rather than paying for an intangible-property right, so they were service B&O income.

2013-12-27

Could an Internet marketing business obtain waiver of Washington tax, penalties, and interest because it relied on alleged oral Department advice about apportionment?

No. Washington taxpayer rights protect detrimental reliance on specific official written advice or written reporting instructions, not telephone or in-person oral guidance.

2013-12-26

Were fixed rent and production royalties under a 30-year sand-and-gravel agreement exempt Washington real-estate rental income?

No. The agreement principally granted a limited right to extract and process sand and gravel—a profit a prendre or mineral license—not exclusive possession and absolute control of the land. Both…

2013-12-23

Were leases of removable, unlit dark fiber taxable competitive telephone services rather than nontaxable leases of real property?

Yes. Dark fiber was telecommunications equipment or apparatus, and the leased strands were removable from their conduit and therefore were not fixtures or real property.

2013-12-19

Were reusable bedside programmable infusion pumps exempt from Washington retail sales tax as drug-delivery or prosthetic devices?

No. The pumps were reused, met the definition of taxable durable medical equipment, and were not worn in or on the body. A Department rule could not create an exemption absent statutory authority.

2013-12-17

Could a Washington dentistry practice have a valid B&O and use-tax assessment reduced because paying it would create financial hardship?

No. Financial hardship did not authorize the Appeals Division to cancel properly due tax, interest, or penalties, and the practice offered no evidence disproving the audit.

2013-12-10

Could a company retroactively claim Washington's 2011 R&D B&O credit after missing the April 30, 2012 annual-survey deadline?

No. Lack of knowledge about the credit was not beyond the company's control, and it neither filed the survey on time nor requested the available extension.

2013-12-10

Could a real-estate brokerage exclude associate expense payments and client commission rebates from Washington B&O tax without complete supporting records?

No. Full commissions and associate payments for costs the brokerage itself owed were gross income, and unsupported claims of tax-paid purchases or duplicate ledgers could not reduce the audit.

2013-12-06

Could Washington correct an audit-workbook error that increased one tax category after the limitation period when the revised assessment reduced every year's total?

Yes. The limitation rule barred an overall increase for closed years, not a mathematical correction that increased one category while reducing each year's total assessment.

2013-12-04

Are emergency water-damage and flood-cleanup services excluded from Washington retail tax as janitorial services?

No. The Department treated specialized cleanup required by floods or other emergencies as taxable retail cleaning, not regular and normal janitorial service.

2013-12-03

Were nonperiodic charter-vessel leases sourced to Washington when customers received the vessels there but used them both inside and outside the state?

Yes. Destination sourcing used the Washington receipt location, and the lessor's lack of awareness did not authorize waiver of uncollected sales tax.

2013-12-02

Were tandem skydiving packages, elevation flights, and customer videos exempt from Washington retail taxes because federal aviation law applied or a prior audit missed them?

No. Customers primarily bought an amusement experience rather than air transportation or instruction, the Anti-Head Tax Act did not preempt Washington tax, and prior audit silence created no waiver…

2013-11-27

Did private subcontract clauses saying the contract price included sales tax prove that a general contractor had already paid Washington retail sales tax?

No. A private agreement was not public advertising and could not overcome the conclusive presumption that the quoted price excluded tax, though documented invoices supported adjustments.

2013-11-27

Was a homeowner liable for Washington tax and the $10-per-pack penalty on 4,000 unstamped cigarette packs seized from the home?

Yes. The cigarettes were found at the taxpayer's property, unsupported claims about other occupants did not rebut possession, and no external cause justified waiver.

2013-11-26

Could affiliated companies claim Washington high-tech R&D credits without timely surveys and both count the same subcontracted research receipts?

No. The required surveys were not filed for the relevant year, and the contracting company could not duplicate the subcontractor's credit without an assignment.

2013-11-21

Could a meat wholesaler exclude affiliate sales from Washington B&O tax by calling itself the affiliate's purchasing agent?

No. Its agreements and accounting records did not show purchases made in the affiliate's name and for its account, so the wholesaler failed Rule 159's agency requirements.

2013-11-13

Were hotel wages paid directly by owners through a payroll processor excluded from the management companies' Washington B&O tax base?

No. Paying the managers' employee costs directly still provided value for their services, and Rule 111 failed because the managers were the employers and personally liable for the wages.

2013-11-13

Could a franchisor exclude licensees' sales-promotion fees from Washington B&O tax as cooperative-advertising reimbursements?

No. The fees became the franchisor's property, it controlled their use, and the agreement did not make it a mere conduit or satisfy the cooperative-advertising conditions.

2013-11-07

Could an aircraft-component manufacturer retroactively claim Washington's preferential aerospace B&O rate after filing the required annual reports years late?

No. Reports for 2008 and 2009 were due the following March because the preferential rate had to be used with timely reporting, not claimed later through a refund.

2013-11-06

Did Washington uphold a 50 percent evasion penalty when a landscaper collected sales tax but reported its receipts as service income and kept the tax?

Yes. Customer invoices proved the landscaper knew sales tax was due, and its deliberate failure to report and remit the collected amounts established intent to evade.

2013-11-06

Could a medical clinic exclude patient receipts passed to its independent-contractor physician as advances or reimbursements under Rule 111?

No. The clinic provided medical services through the contractor, showed no agency relationship with patients, and owed the physician under its own contract rather than solely as the patients' agent.

2013-10-31

Where were receipts from aerospace technical-manual services attributed when the provider could not identify where the equipment was used?

Washington used the next step in the receipts-attribution hierarchy: the state from which the customer ordered the service. Projects initiated by the customer's Washington office were attributable…

2013-10-29

Did a quarry's screener, wash plant, and sand screw qualify for Washington's manufacturing machinery-and-equipment tax exemption?

No. Washing and screening material that was never crushed or blended remained extracting, not manufacturing. The screener had some qualifying use on cobbles later crushed or blended, but those…

2013-10-24

Was a transfer of a 50% property interest a REET-exempt gift when the other owner began paying the entire joint mortgage but did not refinance it?

No. Full payment by the other owner relieved the transferor of debt and supplied consideration even without refinancing. REET applied to 50% of the remaining mortgage balance.

2013-10-21

Could Washington assess use tax after four years on trucks and trailers that had lost the interstate motor-carrier exemption in an earlier year?

No. The tax arose when the rolling stock failed the annual substantial-use test, and mere failure to report was not material misrepresentation extending the assessment period.

2013-10-16

Could an electrical subcontractor treat federal-property construction as wholesale work because prime contractors supplied resale certificates or reseller permits?

No. The subcontractor was a government contractor and consumer liable for tax on incorporated materials; resale documents did not convert the work to wholesale sales.
