Any taxpayer aggrieved by any order, ruling, or finding of the Oklahoma Tax Commission directly affecting the taxpayer or aggrieved by a final order of the Tax Commission issued pursuant to subsection G of Section 221 of this title may appeal therefrom directly to the Supreme Court of Oklahoma. Provided, any taxpayer appealing from a final order of the Tax Commission assessing a tax or an additional tax or denial of a claim for refund may opt to file an appeal in district court as provided in subsection D of this section.

B. Within thirty (30) days after the date of mailing to the taxpayer of the order, ruling, or finding complained of, the taxpayer desiring to appeal shall:

C. Upon request of the taxpayer, the Tax Commission shall furnish the taxpayer a copy of the proceedings had in connection with the matter complained of.

D. In lieu of an appeal to the Supreme Court, any taxpayer aggrieved by a final order of the Tax Commission assessing a tax or an additional tax or denial of a claim for refund may opt to file an appeal for a trial de novo in the district court of Oklahoma County or the county in which the taxpayer resides. If the amount in dispute exceeds Ten Thousand Dollars ($10,000.00), the appeal shall be heard by a district or associate district judge sitting without a jury. If the amount in dispute does not exceed Ten Thousand Dollars ($10,000.00), the appeal may be heard by a special judge sitting without a jury. An order resulting from a trial provided pursuant to this subsection shall be appealable directly to the Supreme Court of Oklahoma by either party. Such appeal shall be taken in the manner and time provided by law for appeal to the Supreme Court from the district court in civil actions. Upon the filing of an appeal, the order of the district court shall be superseded and neither party shall be required to give bond. The provisions of this subsection shall be applicable for tax periods beginning after January 1, 2014. Provided, if the order applies to multiple tax periods which begin before and after January 1, 2014, the appeal provided by this subsection shall be available to the aggrieved taxpayer.

E. If the appeal is from an order of the Tax Commission or a district court denying a refund of taxes previously paid and if upon final determination of the appeal, the order denying the refund is reversed or modified, the taxes previously paid, together with interest thereon from the date of the filing of the petition in error at the rate provided in subsection A of Section 217 of this title, shall be refunded to the taxpayer by the Tax Commission.

F. Such refunds and interest thereon shall be paid by the Tax Commission out of monies in the Tax Commission clearing account from subsequent collections from the same source as the original tax assessment, provided that in the event there are insufficient funds for refunds from subsequent collections from the same source, the refund shall be paid by the Tax Commission from monies appropriated by the Legislature to the special refund reserve account for such purposes as hereinafter provided. There is hereby created within the official depository of the State Treasury an agency special account for the Tax Commission for the purpose of making such refunds as may be required under this section, not otherwise provided. This account shall consist of monies appropriated by the Legislature for the purpose of making refunds under this section.

G. If the appeal be from an order, judgment, finding, or ruling of the Tax Commission other than one assessing a tax and from which a right of appeal is not otherwise specifically provided for in this article, the Uniform Tax Procedure Code, any aggrieved taxpayer may appeal from that order, judgment, finding, or ruling as provided in this section. The filing of such an appeal shall supersede the effect of such order, judgment, ruling, or finding of the Tax Commission.

H. This section shall be construed to provide to the taxpayer a legal remedy by action at law in any case where a tax, or the method of collection or enforcement thereof, or any order, ruling, finding, or judgment of the Tax Commission is complained of, or is sought to be enjoined in any action in any court of this state or the United States of America.

I. All hearings held in proceedings pursuant to this section shall be confidential and shall be held in closed court without admittance of any person other than interested parties, their counsel, and employees of the Oklahoma Tax Commission and its counsel. Information designated by a party as confidential that is filed with or submitted to the Supreme Court or district court in conjunction with any proceeding pursuant to this section shall not constitute a public record and shall be sealed by the court. Any party seeking to file confidential materials shall place the materials in a sealed manila envelope clearly marked with the caption and case number, the word “CONFIDENTIAL”, and a reference to this section of the Oklahoma Statutes.
