(1) An affiliated group of C corporations, as defined in section 1504 of the internal revenue code, may elect to make a consolidated return with respect to the corporate income tax imposed by section 39-22-301 (1) for the taxable year in lieu of separate returns. The making of a consolidated return shall be upon the condition that all C corporations which at any time during the taxable year have been members of the affiliated group consent to be included in such return. The making of a consolidated return shall be considered as such consent. Such election may not be revoked in less than four years unless approved by the executive director.
(2) The executive director shall prescribe such regulations as the executive director may deem necessary in order that the tax liability of any affiliated group of C corporations making a consolidated return and of each C corporation in the group, both during and after the period of affiliation, may be returned, determined, computed, assessed, collected, and adjusted, in such manner as clearly to reflect the income tax liability and the various factors necessary for the determination of such liability and as the executive director may deem necessary in order to prevent avoidance of the tax liability.
