Can Utah tax nonresident property owners at higher rates? Dennis v. Summit County Explained

In Dennis v. Summit County, the Utah Supreme Court addressed whether the state’s residential property tax exemption unconstitutionally discriminates against nonresident property owners. The case arose when out-of-state vacation home owners challenged the 45% residential exemption available only for properties used as primary residences.

Background and Facts: The plaintiffs owned residential properties in Utah that they used for vacation and recreational purposes. Because these properties were not their primary residences, the taxing authorities assessed property taxes on 100% of fair market value instead of the reduced 55% rate available under Utah Code sections 59-2-102(22) and 59-2-103(2). The plaintiffs sued, claiming this violated article III, section 2 of the Utah Constitution, which requires equal taxation of lands belonging to residents and nonresidents.

Key Legal Issues: The central question was whether the residential property tax exemption impermissibly discriminated based on residency status. Plaintiffs argued the exemption effectively denied nonresidents equal treatment since they could not establish primary residences in Utah while maintaining primary residences elsewhere. The defendants countered that the exemption was based on property use rather than owner residency.

Court’s Analysis and Holding: The court applied a correctness standard to the constitutional question and held that the exemption did not discriminate based on residency. The statute defines “residential property” as property “used for residential purposes as a primary residence,” making the crucial qualification the property’s use, not the owner’s residency. Both residents and nonresidents who own property not used as a primary residence face the same tax treatment. The court distinguished cases involving explicit residency-based discrimination.

Practice Implications: This decision reinforces that constitutional equal protection analysis focuses on the actual statutory criteria rather than disparate practical effects. Tax exemptions based on legitimate use classifications will survive constitutional scrutiny even if they disproportionately affect certain groups. Practitioners challenging tax statutes must demonstrate actual discrimination in the law’s terms, not merely unequal outcomes.
