2021 Oklahoma Statutes|Title 68. Revenue and Taxation|§68-226. Action to recover taxes as additional remedy to aggrieved taxpayer.

|(a) In addition to the right to a protest of a proposed assessment as authorized by Section 221 of this title, a right of action is hereby created to afford a remedy to a taxpayer aggrieved by the provisions of this article or of any other state tax law, or who resists the collection of or the enforcement of the rules or regulations of the Tax Commission relating to the collection of any state tax; however, such remedy shall be limited as prescribed by subsection (c) of this section. |(b) Within thirty (30) days from the date of mailing to the taxpayer of an assessment for taxes or additional taxes pursuant to Section 221 of this title by the Tax Commission, any such taxpayer shall pay the tax to the Tax Commission, and at the time of making such payment shall give notice to the Tax Commission of his intention to file suit for recovery of such tax. The taxpayer shall not be required to file suit within such thirty-day period in order to prosecute an action as authorized by this section; however, failure to file such suit within one (1) year from the date of mailing of the assessment shall result in the assessment becoming final and absolute. If the taxpayer prevails the Tax Commission shall, by cash voucher drawn by the Tax Commission upon its official depository clearing account or special refund reserve account with the State Treasurer, refund to the taxpayer the amount of tax determined not to be due pursuant to the final judgment of the court having jurisdiction, together with interest on such amount at the rate applicable to money judgments in civil cases from the date of payment by the taxpayer to the date of the refund by the Tax Commission. The refunds paid shall be payable as provided in Section 225(d). If the taxpayer prevails and the court determines that the position of the Tax Commission in the proceeding was not substantially justified, the court shall award the taxpayer a judgment for reasonable attorney fees, reasonable expenses of expert witnesses in connection with the proceeding and reasonable costs of any study, analysis, engineering report, test or project which is found by the court to be necessary for the preparation of the taxpayer's case.(c) This section shall afford a legal remedy and right of action in any state or federal court having jurisdiction of the parties and the subject matter. It shall be construed to provide a legal remedy in the state or federal courts by action at law only in cases where the taxes complained of are claimed to be an unlawful burden on interstate commerce, or the collection thereof violative of any Congressional Act or provision of the Federal Constitution, or in cases where jurisdiction is vested in any of the Courts of the United States. In all actions brought hereunder service of process upon the Chairman of the Tax Commission shall be sufficient service, and the Tax Commission shall be the sole, necessary and proper party defendant in any such suit, and the State Treasurer shall not be a necessary or proper party thereto.(d) Upon request of any taxpayer and upon proper showing that the principle of law involved in the assessment of any tax is already pending before the courts for judicial determination, the taxpayer, upon agreement to abide by the decision of the court, may pay the tax so assessed under protest, but need not file a suit.Laws 1965, c. 414, § 2; Laws 1978, c. 211, § 2, emerg. eff.
