Kinder Morgan CO2 Co., L.P. v. Montezuma Cty. Bd. of Comm'rs
Annotate this CaseThe Colorado Supreme Court concluded that the statutory scheme property taxation of oil and gas leaseholds authorized the retroactive tax assessment in this case. Petitioner Kinder Morgan CO2 Company, L.P., operated oil and gas leaseholds in Montezuma County, Colorado. In 2009, the assessor for Montezuma County issued a corrective tax assessment on these leaseholds for the previous tax year, retroactively assessing over $2 million in property taxes, after an auditor concluded that Kinder Morgan underreported the value of gas produced at the leaseholds. Kinder Morgan appealed, arguing the assessor lacked authority to retroactively assess these taxes because Colorado law did not authorize a retroactive assessment when an operator has correctly reported the volume of oil and gas sold but has underreported the selling price at the wellhead. In affirming the court of appeals in this matter, the Supreme Court further concluded that the Board of Assessment Appeals did not err in determining that Kinder Morgan underreported the selling price by claiming excess transportation deductions, given Kinder Morgan’s relationship to the owner of the pipeline through which the gas was transported.
