This bill implements recommendations from Washington’s tax preference performance review process by eliminating 39 obsolete or unused tax preferences, updating rates and conditions for remaining preferences (e.g., for aerospace, agriculture, and health care), and adding new legislative findings to guide future reviews. It also clarifies how taxes apply to interstate activity and adjusts expiration dates for several key preferences.

  • Eliminates 39 obsolete or unused tax preferences, including credits and exemptions for clean alternative fuel vehicles, aluminum and silicon smelters, and various business activities.
  • Clarifies and updates tax rates for manufacturing, processing, and wholesale sales of agricultural, seafood, dairy, timber, and aerospace products, including new expiration dates and conditions for preferential rates.
  • Adds a 1.22% workforce education investment surcharge on select advanced computing businesses (e.g., cloud computing, software development, online marketplaces) with a $9M annual cap per affiliated group.
  • Revises property tax exemptions for nonprofit hospitals, cancer clinics, and dialysis centers, and adds new legislative findings to guide future performance reviews of those exemptions.
  • Extends several tax preferences (e.g., aerospace, commuter air carrier, and qualified investment project deferrals) through 2036 and updates their performance review requirements.
  • Clarifies that the public utility tax applies to the in-state portion of interstate activity and provides authority for equitable apportionment methods.
  • Modifies definitions and references across multiple tax statutes to improve consistency and administrative clarity, including updates to affiliate rules, tax credit calculations, and reporting requirements.

Who is affected

  • Agricultural, seafood, dairy, timber, and aerospace manufacturersBusinesses that manufacture or process agricultural products, seafood, dairy, timber, or aerospace products may see changes in their tax rates or eligibility for preferential rates, depending on the product, timing, and business structure.
  • Health insurance providers and health maintenance organizationsHealth plans, HMOs, and other health care service contractors will continue to pay a 2% premium tax, but with clarified exemptions and updated deposit requirements for exchange-related premiums.
  • Nonprofit health care providersNonprofit hospitals, cancer clinics, and dialysis centers may benefit from property tax exemptions and specific tax deductions, with new legislative intent to evaluate the effectiveness of those exemptions.
  • Aerospace and large technology companiesLarge aerospace and computing companies may be subject to new or adjusted surcharges and tax rates, while smaller businesses and certain nonprofits may qualify for reduced rates or credits.
  • Transportation and air carrier businessesCommuter air carriers and other transportation businesses may benefit from tax exemptions or reduced rates for certain in-state services, while also being subject to clarified rules on how taxes apply to interstate activity.
Effective: January 1, 2026Fiscal impact: The bill eliminates obsolete tax preferences and modifies several existing ones, which is expected to increase state revenue over time. However, it also extends or modifies certain credits and exemptions (e.g., for low-income housing, aerospace, and commuter air carriers), which may partially offset revenue gains. The workforce education investment surcharge (1.22%) on select advanced computing businesses is dedicated to a specific education account, and the bill includes a $7.5M annual cap on rural job creation tax credits.Sunset: Multiple sunset dates apply; key ones include January 1, 2030 (e.g., for low-income housing exemptions), January 1, 2034 (e.g., for some manufacturing and commuter air carrier provisions), and January 1, 2036 (e.g., for aerospace and qualified investment project preferences).

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (5)
  • Eliminating the clean alternative fuel vehicle tax exemptions increases state revenue, which can be redirected to fund broader clean energy initiatives and infrastructure that benefit all Washingtonians, not just vehicle owners.

    EnvironmentPeopleRef: Sec. 101(11)
  • Extending the preferential tax rate for seafood manufacturers through 2035 provides long-term certainty for coastal communities dependent on the fishing industry, supporting jobs and economic stability in rural areas.

    Business & EmploymentPeopleRef: Sec. 102(1)(b)
  • The 0.138% preferential rate for dairy products through 2046 supports Washington's dairy industry, which employs thousands and contributes significantly to the state's agricultural economy, particularly in rural counties.

    Business & EmploymentPeopleRef: Sec. 103(1)(c)(i)
  • The 1.5% tax rate for businesses with gross income under $1M (and not affiliated with larger groups) provides relief to small businesses, helping them compete in Washington's business environment.

    Business & EmploymentPeopleRef: Sec. 104(1)(a)
  • The 1.22% workforce education investment surcharge on advanced computing businesses, dedicated to the workforce education investment account, creates a dedicated funding stream for job training programs that benefit workers statewide.

    EducationPeopleRef: Sec. 110(3)
Potential Concerns (5)
  • The bill eliminates obsolete tax preferences, including exemptions for clean alternative fuel vehicles and aluminum/silicon smelters, which reduces state revenue. While this improves fiscal sustainability, it may reduce incentives for clean energy adoption and could increase compliance complexity for businesses adjusting to new rules.

    Local GovernmentRef: Sec. 101(11)
  • The dairy products tax preference includes a restriction that the preferential rate does not apply to sales where dairy products are used by purchasers as ingredients in manufacturing dairy products in Washington. This creates complexity for dairy processors and may increase costs for businesses that rely on in-state dairy supply chains.

    Business & EmploymentRef: Sec. 102(1)(c)(iii)
  • The bill modifies the B&O tax rate structure, creating a tiered system where businesses with gross income under $1M pay 1.5% while larger businesses pay 1.75%. However, the $1M threshold and affiliate aggregation rules create administrative complexity and may disadvantage small businesses trying to stay below the threshold.

    Business & EmploymentRef: Sec. 104(1)(a)
  • The new 1.22% workforce education investment surcharge on select advanced computing businesses includes exclusions for financial institutions, telecommunications infrastructure providers, and commercial mobile service providers. This creates competitive distortions by favoring certain business models over others in the tech sector.

    Business & EmploymentRef: Sec. 110(1)(f)
  • The surcharge exemption for hospitals and provider clinics may reduce revenue for the workforce education investment account, potentially limiting funding for training programs. However, it prevents double taxation of healthcare providers who already face high operational costs.

    HealthcareRef: Sec. 110(2)(a)
