Item 8.01. Other Events.

On March 30, 2026, the United States Tax Court issued an opinion granting the Internal Revenue Service’s motion for partial summary judgment and denying the Company’s motion for partial summary judgment in Barrett Business Services, Inc. v. Commissioner of Internal Revenue with respect to the Company’s claims for wage-based tax credits, including the Work Opportunity Tax Credit and the Empowerment Zone Employment Credit, for tax years 2017 through 2020. The ruling did not determine the amounts of any tax deficiency, interest or penalties.

As a result of the Court’s opinion, the Company expects to record charges of approximately $8.6 million of additional tax expense and approximately $3.4 million of related interest in the first fiscal quarter of 2026 related to the tax years addressed by the opinion, as well as for tax years 2021 and 2022, which represent the remaining years of the Company’s potential exposure related to wage-based tax credits. The Company does not intend to record a charge for penalties, as it believes the matter involves novel legal issues, such that penalties should not apply.

The Company is evaluating the opinion and available legal options, including any rights to appeal. The Company does not expect the ruling to have an effect on its current operations or services provided to clients.
