What different users should do first

Sellers

  • Map each service line to a DOR category, exclusion, or non-retail service position.
  • Update invoice, POS, and customer-notice workflows for taxable sales made on or after October 1, 2025.
  • Keep sourcing support: contracts, statements of work, invoice allocation, purchaser address data, and usage data where relevant.

Buyers

  • Expect vendors to add sales tax on listed services when no exclusion or exemption applies.
  • Ask how multistate services, especially advertising, are being sourced before approving the charge.
  • Preserve exemption, reseller permit, direct-pay, or MPU documentation before relying on it.

CPAs / advisors

  • Keep retail-sales-tax sourcing separate from B&O service-income attribution.
  • Screen existing contracts, bundled services, affiliate transactions, and resale/subcontractor arrangements.
  • Treat interim guidance, rulemaking, and litigation as required status checks before final advice.

Sourcing / place of receipt

Retail sales tax uses sourcing and place-of-receipt concepts to decide where a retail sale occurs. Service-income apportionment uses attribution to decide where service receipts belong for B&O apportionment. Do not collapse those two analyses into one rule.

Advertising services

DOR's advertising guidance treats digital and nondigital services related to creating, preparing, producing, or disseminating ads as the main category — including online referrals, search engine marketing, lead generation optimization, web campaign planning, internet media acquisition, and website traffic analysis.

For sourcing, DOR points to the retail-sales-tax hierarchy in RCW 82.32.730: seller business location if received there, known receipt location, purchaser address in business records, purchaser address obtained at sale, then a seller-provided location. For disseminated advertising, DOR focuses on where the result is first used — where ads are disseminated, viewed, or interacted with. Pre-dissemination creative services can require a different receipt analysis.

Multiple Points of Use (MPU / DAS)

DOR's FAQ says digital advertising services may use MPU only when they meet the DAS definition and are used concurrently inside and outside Washington. If eligible, use tax is apportioned based on first use, generally where viewers or interactors are located. This is a cautious tracker item, not a blanket rule — bundling, records, due diligence, and the DAS definition can change the analysis.

DOR ESSB 5814 FAQ

2026 legislative changes (ESSB 6113 and ESSB 6346)

ESSB 6113 is the verified 2026 retail-services source handle. It clarifies definitions and exclusions (temporary staffing, live presentations, advertising sourcing) and addresses use tax for newly enacted retail services. ESSB 6346's bill reports connect the millionaires-tax package to tax relief and state that most ESSB 5814 retail-services sales and use taxes are repealed effective January 1, 2029, except advertising services.

FAQ

Is every listed service automatically taxable? No. Read this as a category screen, not a final answer. A transaction still needs to fit the statutory category, avoid exclusions, and be checked against DOR interim guidance.

Is retail-sales-tax sourcing the same as B&O attribution? No. Retail sales tax uses sourcing and place-of-receipt concepts; B&O service-income apportionment uses attribution. Advertising is a common place those get mixed up.

Can digital advertising use the MPU exemption? Sometimes — DOR's FAQ and advertising guidance point to MPU only when the service also qualifies as a DAS and is used concurrently inside and outside Washington.

Does the 2029 repeal remove all of these taxes? Not as currently described. ESSB 6346 materials say most ESSB 5814 retail-services sales and use taxes are repealed effective January 1, 2029, except advertising services.

What records matter most? Contracts, statements of work, invoices, purchaser location records, allocation support, viewer/targeting data for advertising, exemption certificates, reseller permits, and direct-pay or MPU support.
