(A) The tax commissioner shall direct and supervise the assessment for taxation of all real property. The commissioner shall adopt, prescribe, and promulgate rules for the determination of true value and taxable value of real property by uniform rule for such values and for the determination of the current agricultural use value of land devoted exclusively to agricultural use. The uniform rules shall prescribe methods of determining the true value and taxable value of real property and shall also prescribe the method for determining the current agricultural use value of land devoted exclusively to agricultural use, which method shall reflect standard and modern appraisal techniques that take into consideration: the productivity of the soil under normal management practices; the average price patterns of the crops and products produced to determine the income potential to be capitalized; the market value of the land for agricultural use; and other pertinent factors. The rules shall provide that in determining the true value of lands or improvements thereon for tax purposes, all facts and circumstances relating to the value of the property, its availability for the purposes for which it is constructed or being used, its obsolete character, if any, the income capacity of the property, if any, and any other factor that tends to prove its true value shall be used. In determining the true value of minerals or rights to minerals for the purpose of real property taxation, the tax commissioner shall not include in the value of the minerals or rights to minerals the value of any tangible personal property used in the recovery of those minerals.
(B) The taxable value shall be that per cent of true value in money, or current agricultural use value in the case of land valued in accordance with section 5713.31 of the Revised Code, the commissioner by rule establishes, but it shall not exceed thirty-five per cent. The uniform rules shall also prescribe methods of making the appraisals set forth in section 5713.03 of the Revised Code. The taxable value of each tract, lot, or parcel of real property and improvements thereon, determined in accordance with the uniform rules and methods prescribed thereby, shall be the taxable value of the tract, lot, or parcel for all purposes of sections 5713.01 to 5713.26, 5715.01 to 5715.51, and 5717.01 to 5717.06 of the Revised Code. County auditors shall, under the direction and supervision of the commissioner, be the chief assessing officers of their respective counties, and shall list and value the real property within their respective counties for taxation in accordance with this section and sections 5713.03 and 5713.31 of the Revised Code and with such rules of the commissioner. There shall also be a board in each county, known as the county board of revision, which shall hear complaints and revise assessments of real property for taxation.
(C) The commissioner shall neither adopt nor enforce any rule that requires true value for any tax year to be any value other than the true value in money on the tax lien date of such tax year or that requires taxable value to be obtained in any way other than by reducing the true value, or in the case of land valued in accordance with section 5713.31 of the Revised Code, its current agricultural use value, by a specified, uniform percentage.
