OXY USA Inc. v. Mesa County Board of Commissioners
Annotate this CaseIn 2011, OXY USA Inc. (“Oxy”), made a mistake that caused it to overpay its property taxes on oil and gas produced from leaseholds. Oxy failed to deduct certain costs it was entitled to deduct. By the time it realized the mistake, the protest period had expired. The company nonetheless contended it was entitled to abatement and refund of the overpayment pursuant to section 39-10-114(1)(a)(I)(A), C.R.S. (2017). The county board of commissioners maintained that the abatement-and-refund provision did not apply because Oxy was the sole source of the error. Relying on Colorado Supreme Court precedent, the court of appeals held that Oxy couldn't receive abatement and refund for overpayment due to its own mistake. The Supreme Court held section 39-10-114(1)(a)(I)(A) gave taxpayers the right to seek abatement and refund for erroneously or illegally levied taxes resulting from overvaluation caused solely by taxpayer mistake. Therefore, Oxy was entitled to abatement and refund for its overpayment of taxes in the tax year at issue in this appeal.
