Alaska Supreme Court rules Sleep Clinic owes back taxes, not a small business

The Alaska Supreme Court ruled Friday that Alaska Sleep Clinic owes additional net income taxes for 2016, 2017, and 2018, affirming the state's denial of a small business tax exemption the clinic had claimed since it incorporated in February 2015.

The court found the clinic performs services in the field of health, which disqualifies it from the exemption under Alaska law. The Department of Revenue's 2020 denial increased the clinic's tax liability for all three years.

The decisive factor was the role of medical director Dr. Mauricio Reinoso, a pulmonary and board-certified sleep specialist. He testified that he does not see, diagnose, or treat patients directly. But the court found that his review of every patient referral, applying independent clinical judgment to determine which sleep study is appropriate, went well beyond what a typical lab director does. Justice Borghesan, writing for the court, said the state correctly determined the clinic performed services in the field of health based on findings supported by substantial evidence, including evidence about "the role of the corporation's highly trained medical director, its staff's interaction with patients, and its expertise-and-skill-focused marketing."

The court also applied the rule that tax exemptions must be construed narrowly in favor of the taxing authority, which it said tipped the balance further toward the conclusion that the clinic performs services in the field of health.

The Timeliness Argument

The clinic argued the state acted too late, contending the Department of Revenue had to determine exemption eligibility on the first day of each tax year. The court rejected that reading. The applicable statute of limitations governs when the state must act, not the first day of the tax year.

The court also gave no weight to a 2024 IRS private letter ruling that concluded the clinic was not engaged in a trade or business involving the performance of services in the field of health. The ruling addressed tax year 2024, not the 2016 through 2018 years at issue, and its statement of facts omitted several findings the court found decisive, including the medical director's patient-by-patient screening role and the clinic's skill-focused marketing. A private letter ruling binds only the IRS for the specific taxpayer's described transaction and cannot be relied on as precedent.
