Mississippi Code Title 27. Taxation and Finance § 27-31-19.1

(1) A person, firm, or corporation operating a refinery for the refining of oil, gas or petroleum products and owning oil, gas or petroleum products, whether produced within or without the state, which (a) are located at such a refinery prior to being refined, (b) are in the process of being refined at such refinery, or (c) have been refined at such refinery and are stored at such refinery, and which are subject to ad valorem taxes levied or hereafter levied by any county, municipality, levee district, school district or any other taxing authority of the state or a political subdivision thereof shall be allowed a tax credit for the amount of all ad valorem taxes payable by the person, firm or corporation that are attributable to such oil, gas or petroleum products. The tax credit may be applied against other ad valorem taxes payable on other taxable refinery property of such person, firm or corporation by the same county, municipality, levee district, school district or any other taxing authority of the state or a political subdivision thereof. However, the amount of credit that may be utilized during a taxable year cannot exceed the ad valorem tax liability of the person, firm or corporation on such other property for the taxable year. The tax credit provided by this section shall also extend to ad valorem taxes payable that are attributable to such oil, gas and petroleum products owned by any corporation controlled by or under common control with, or controlling such refiner; however, the tax credit shall not extend to those finished petroleum products no longer at the refinery incident to regular, normal and customary marketing operations held in temporary storage at marketing bulk plants outside refinery property, including storage facilities from which a finished product is marketed in the state and from which a finished product is shipped out of the state for marketing, or at retail service stations.

(2) The administration of the tax credit provided by this section will be performed by the tax assessor and/or tax collector of the county in which each refinery is located, and may include a credit applied by the tax assessor against the assessed value of other taxable property, or a credit applied by the tax collector against taxes on other taxable property which have been determined but not yet billed.

(3) Any amount of ad valorem taxes applied and used as a tax credit under Section 27-7-22.5, Mississippi Code of 1972, may not be applied and used as a tax credit under this section.
