Washington imposes a tax on insurers equal to two percent of all premiums the insurer collects or receives, subject to certain exceptions. This premium tax is imposed in lieu of all other taxes, except as otherwise provided. Accordingly, Washington provides an exemption from its business and occupation (B&O) tax for any person, in respect to insurance business, upon which a tax based on gross premiums is paid to the state, subject to various exceptions.
In 1962, Armstrong v. State, the Washington Supreme Court recognized the in-lieu-of nature of the state's insurance premium tax and noted it reflected a legislative decision to consider the gross premium tax as the exclusive tax on insurance company operations while exempting such entities from the state B&O tax.
In 2024, Envolve Pharmacy Solutions, Inc. v. Dept of Revenue, the Washington Supreme Court held the insurance premium exemption from the B&O tax applied to a pharmacy benefit manager and potentially other business entities that do not directly earn premium income or pay a premium tax. The court reasoned the exemption's statutory text did not require the insurance business doing the work at issue to directly pay a premium tax on that business to qualify for the exemption. Instead, the court reasoned, the legislature used the passive voice to say that a premium tax must have been paid on the business, without describing by whom, for the tax exemption to apply.
The insurance premium exemption to the B&O tax is modified by expressly limiting its scope to: (1) gross premiums received by an insurer upon which the same insurer paid insurance premium taxes pursuant to state law; and (2) gross premiums received by an insurer that is exempt from premium taxes pursuant to state law.
The insurance premium exemptions to the B&O tax for qualifying insurers and health maintenance organizations are consolidated into a single section in the revised code.
This change to the insurance premium exemption to the B&O tax applies both prospectively and retroactively to October 2, 2019. The act does not affect any final judgment that is no longer subject to appeal and entered by a court of competent jurisdiction before the act's effective date.
