§ 40-18-16. Depreciation.

(a) Basis for depreciation. The basis upon which exhaustion, wear and tear, depreciation and obsolescence are to be allowed shall be such reasonable allowance as may be determined by the Department of Revenue on the adjusted basis provided in Section 40-18-6 for the purpose of determining the gain or loss upon sale or other disposition of such property.

(b) Basis for depletion.

(1) GENERAL RULE. The basis upon which depletion is to be allowed shall be such reasonable allowance as may be determined by the Department of Revenue on the adjusted basis provided in Section 40-18-6 for the purpose of determining the gain or loss upon the sale or other disposition of such property, except as provided in subdivision (2) of this subsection.

(2) AMOUNT. In the case of oil and gas wells, the allowance for depletion shall be 12 percent of the gross income from the property during the taxable year, excluding from such gross income an amount equal to any rents or royalties paid or incurred by the taxpayer in respect to the property. Such amounts shall not exceed 50 percent of the net income of the taxpayer, computed without allowance for depletion, from the property, except that in no case shall the depletion allowance be less than the amount allowable under federal income tax law. In the case of leases the deductions allowed by this paragraph shall be equitably apportioned between the lessor and the lessee.
