§ 1.1502-6. Liability for tax.

¶(a) Several liability of members of group. Except as provided in paragraph (b) of this section, the common parent corporation and each subsidiary which was a member of the group during any part of the consolidated return year shall be severally liable for the tax for such year computed in accordance with the regulations under section 1502 prescribed on or before the due date (not including extensions of time) for the filing of the consolidated return for such year.

¶(b) Liability of subsidiary after withdrawal. If a subsidiary has ceased to be a member of the group and in such cessation resulted from a bona fide sale or exchange of its stock for fair value and occurred prior to the date upon which any deficiency is assessed, the Commissioner may, if the Commissioner believes that the assessment or collection of the balance of the deficiency will not be jeopardized, make assessment and collection of such deficiency from such former subsidiary in an amount not exceeding the portion of such deficiency which the Commissioner may determine to be allocable to it. If the Commissioner makes assessment and collection of any part of a deficiency from such former subsidiary, then for purposes of any credit or refund of the amount collected from such former subsidiary the agency of the common parent under the provisions of § 1.1502-77 does not apply.

¶(c) Effect of intercompany agreements. No agreement entered into by one or more members of the group with any other member of such group or with any other person shall in any case have the effect of reducing the liability prescribed under this section.
