Washington Bankers Ass'n v. Dep't of Revenue (Majority and Concurrence)Annotate this Case
This case involves the constitutionality of a business and occupation (B&O) tax. In 2019, the Washington state legislature imposed an additional 1.2 percent B&O tax on financial institutions with a consolidated net income of at least $1 billion. The tax applied to any financial institution meeting this threshold regardless of whether it was physically located in Washington, and it was apportioned to income from Washington business activity. The Washington Supreme Court found that because the tax applied equally to in- and out-of-state institutions and was limited to Washington-related income, it did not discriminate against interstate commerce. The Court therefore reversed the trial court and upheld the constitutionality of the tax.
