(a) In general—(1) Computation of tax liability. The tax liability for a consolidated return year of a group of two or more corporations described in section 1504(e) which are exempt from taxation under section 501 (hereinafter referred to in this section as “exempt group”) shall be determined on a consolidated basis by applying the provisions of subchapter F of chapter 1 of the code in the manner provided in this section. See section 1504(e) for tax-exempt corporations eligible to file a consolidated return.

(2) Applicability of other consolidated return provisions. The provisions of § 1.1502-1 through § 1.1502-80 shall be applicable to an exempt group to the extent they are not inconsistent with the provisions of this section or the provisions of subchapter F of chapter 1 of the Code. For purposes of applying the provisions of § 1.1502-1 through § 1.1502-80 to an exempt group, the following substitutions shall be made:

(i) The term “exempt group” shall be substituted for the term “group”,

(ii) The terms “unrelated business taxable income”, “separate unrelated business taxable income”, and “consolidated unrelated business taxable income” shall be substituted for the terms “taxable income”, “separate taxable income”, and “consolidated taxable income”, and

(iii) The term “consolidated liability for tax determined under § 1.1502-2” (or an equivalent term) shall mean the consolidated liability for tax of an exempt group determined under paragraph (b) of this section.

(b) The tax liability for a consolidated return year of an exempt group is the tax imposed by section 511(a) on the consolidated unrelated taxable income for the year (determined under paragraph (c) of this section), and by allowing the credits provided in § 1.1502-2(b).

(c) Consolidated unrelated business taxable income. The consolidated unrelated business taxable income for a consolidated return year shall be determined by taking into account:

(1) The separate unrelated business taxable income of each member of the exempt group (determined under paragraph (d) of this section);

(2) Any consolidated net operating loss deduction (determined under § 1.1502-21A or 1.1502-21 (as appropriate) subject to the limitations provided in section 512(b)(6);

(3) Any consolidated charitable contribution deduction (determined under § 1.1502-24) subject to the limitations provided in section 512(b)(10); and

(4) Any consolidated net gain or net loss from the disposition of debt-financed property (as defined in section 514(b)) taken into account as provided by section 514(a), or from the cutting of timber to which section 631 applies.

(d) Separate unrelated business taxable income. The separate unrelated business taxable income of a member of an exempt group shall be computed in accordance with the provisions of section 512 covering the determination of unrelated business taxable income of separate corporations, except that:

(1) The provisions of paragraphs (a) through (k) and (o) of § 1.1502-12 shall apply; and

(2) No charitable contributions deduction shall be taken into account under section 512(b)(10).
