SolarCity Corp. v. Arizona Department of RevenueAnnotate this Case
The Arizona Department of Revenue (ADOR) is not authorized to value solar panels owned by SolarCity Corporation and Sunrun, Inc. (collectively, Taxpayers) and leased to residential and commercial property owners.
For tax year 2015, ADOR notified Taxpayers that their panels had been assigned full cash values and that taxes would be assessed. Taxpayers sought a declaratory judgment that the panels were considered to have no value under Ariz. Rev. Stat. 42-11054(C)(2) and were not subject to valuation. The tax court ruled that the panels were “general property” that must be valued by county assessors pursuant to section 42-13051(A) and that the county assessors cannot assign a zero value because applying section 42-11054(c)(2)’s zero value provision to the panels would violate the Exemptions Clause and the Uniformity Clause of the Arizona Constitution. The Supreme Court affirmed the tax court’s judgment to the extent it concluded that ADOR lacked statutory authority to value Taxpayers’ leased solar panels but reversed the remainder of the judgment and remanded for a determination as to whether section 42-13054 authorizes county assessors to value the solar panels and, if so, whether section 42-11054(C)(2) requires a zero valuation. If section 42-11054(C)(2) applies, the tax could should determine whether that provision violates the Exemptions Clause or Uniformity Clause.
