For purposes of this subsection, a resulting branch in this State of an out-of-state bank or foreign bank, or a foreign bank branch, foreign bank limited purpose branch, foreign bank agency or a federal branch or agency (all as defined in § 101 of this title) shall be treated as if it were a corporation. The Commissioner shall prescribe such rules and regulations as may be deemed necessary in order that the tax liability of any resulting branch in this State of an out-of-state bank or foreign bank, or any foreign bank branch, foreign bank limited purpose branch, foreign bank agency or federal branch or agency under this subsection may be returned, determined, computed, assessed, collected and adjusted, in such manner as to clearly reflect the tax liability and the various factors necessary for the determination of such liability, and in order to prevent avoidance of such tax liability.
