(a) Taxable year of members of group. The consolidated return of a group must be filed on the basis of the common parent's taxable year, and each subsidiary must adopt the common parent's annual accounting period for the first consolidated return year for which the subsidiary's income is includible in the consolidated return. If any member is on a 52-53-week taxable year, the rule of the preceding sentence shall, with the advance consent of the Commissioner, be deemed satisfied if the taxable years of all members of the group end within the same 7-day period. Any request for such consent shall be filed with the Commissioner of Internal Revenue, Washington, DC 20224, not later than the 30th day before the due date (not including extensions of time) for the filing of the consolidated return.

(b) Items included in the consolidated return—(1) General rules—(i) In general. A consolidated return must include the common parent's items of income, gain, deduction, loss, and credit for the entire consolidated return year, and each subsidiary's items for the portion of the year for which it is a member. If the consolidated return includes the items of a corporation for only a portion of its tax year determined without taking this section into account, items for the portion of the year not included in the consolidated return must be included in a separate return (including the consolidated return of another group). The rules of this paragraph (b) must be applied to prevent the duplication or elimination of the corporation's items.

(ii) The day a corporation becomes or ceases to be a member—(A) End of the day rule. (1) In general. If a corporation (S), other than one described in paragraph (b)(1)(ii)(A)(2) of this section, becomes or ceases to be a member during a consolidated return year, it becomes or ceases to be a member at the end of the day on which its status as a member changes, and its tax year ends for all Federal income tax purposes at the end of that day. Appropriate adjustments must be made if another provision of the Internal Revenue Code or the regulations thereunder contemplates the event occurring before or after S's change in status. For example, S's items restored under § 1.1502-13 immediately before it becomes a nonmember are taken into account in determining the basis of S's stock under § 1.1502-32. On the other hand, if a section 338(g) election is made in connection with S becoming a member, the deemed asset sale under that section takes place before S becomes a member. See § 1.338-10(a)(5) (deemed sale excluded from purchasing corporation's consolidated return.)

(2) Special rule for former S corporations. If S becomes a member in a transaction other than in a qualified stock purchase for which an election under section 338(g) is made, and immediately before becoming a member an election under section 1362(a) was in effect, then S will become a member at the beginning of the day the termination of its S corporation election is effective. S's tax year ends for all Federal income tax purposes at the end of the preceding day. This paragraph (b)(1)(ii)(A)(2) applies to transactions occurring after November 10, 1999.

(B) Next day rule. If, on the day of S's change in status as a member, a transaction occurs that is properly allocable to the portion of S's day after the event resulting in the change, S and all persons related to S under section 267(b) immediately after the event must treat the transaction for all Federal income tax purposes as occurring at the beginning of the following day. A determination as to whether a transaction is properly allocable to the portion of S's day after the event will be respected if it is reasonable and consistently applied by all affected persons. In determining whether an allocation is reasonable, the following factors are among those to be considered—

(1) Whether income, gain, deduction, loss, and credit are allocated inconsistently (e.g., to maximize a seller's stock basis adjustments under § 1.1502-32);

(2) If the item is from a transaction with respect to S stock, whether it reflects ownership of the stock before or after the event (e.g., if a member transfers encumbered land to nonmember S in exchange for additional S stock in a transaction to which section 351 applies and the exchange results in S becoming a member of the consolidated group, the applicability of section 357(c) to the exchange must be determined under § 1.1502-80(d) by treating the exchange as occurring after the event; on the other hand, if S is a member but has a minority shareholder and becomes a nonmember as a result of its redemption of stock with appreciated property, S's gain under section 311 is treated as from a transaction occurring before the event);

(3) Whether the allocation is inconsistent with other requirements under the Internal Revenue Code and regulations promulgated thereunder (e.g., if a section 338(g) election is made in connection with a group's acquisition of S, the deemed asset sale must take place before S becomes a member and S's gain or loss with respect to its assets must be taken into account by S as a nonmember (but see § 1.338-1(d)), or if S realizes discharge of indebtedness income that is excluded from gross income under section 108(a) on the day it becomes a nonmember, the discharge of indebtedness income must be treated as realized by S as a member (see § 1.1502-28(b)(11))); and

(4) Whether other facts exist, such as a prearranged transaction or multiple changes in S's status, indicating that the transaction is not properly allocable to the portion of S's day after the event resulting in S's change.

(C) Successor corporations. For purposes of this paragraph (b)(1)(ii), any reference to a corporation includes a reference to a successor or predecessor as the context may require. A corporation is a successor if the basis of its assets is determined, directly or indirectly, in whole or in part, by reference to the basis of the assets of another corporation (the predecessor). For example, if a member forms S, S is treated as a member from the beginning of its existence.

(iii) Group structure changes. If the common parent ceases to be the common parent but the group remains in existence, adjustments must be made in accordance with the principles of § 1.1502-75(d)(2) and (3).

(2) Determination of items included in separate and consolidated returns—(i) In general. The returns for the years that end and begin with S becoming (or ceasing to be) a member are separate tax years for all Federal income tax purposes. The returns are subject to the rules of the Internal Revenue Code applicable to short periods, as if S ceased to exist on becoming a member (or first existed on becoming a nonmember). For example, cost recovery deductions under section 168 must be allocated for short periods. On the other hand, annualization under section 443 is not required of S solely because it has a short year as a result of becoming a member. (Similarly, section 443 applies with respect to a consolidated return only to the extent that the group's return is for a short period and section 443 applies without taking this paragraph (b) into account.)

(ii) Ratable allocation of a year's items—(A) Application. Although the periods ending and beginning with S's change in status are different tax years, items (other than extraordinary items) may be ratably allocated between the periods if—

(1) S is not required to change its annual accounting period or its method of accounting as a result of its change in status (e.g., because its stock is sold between consolidated groups that have the same annual accounting periods); and

(2) An irrevocable ratable allocation election is made under paragraph (b)(2)(ii)(D) of this section.

(B) General rule—(1) Allocation within original year. Under a ratable allocation election, paragraph (b)(2) of this section applies by allocating to each day of S's original year (S's tax year determined without taking this section into account) an equal portion of S's items taken into account in the original year, except that extraordinary items must be allocated to the day that they are taken into account. All persons affected by the election must take into account S's extraordinary items and the ratable allocation of S's remaining items in a manner consistent with the election.

(2) Items to be allocated. Under ratable allocation, the items to be allocated and their timing, location, character, and source are generally determined by treating the original year as a single tax year, and the items are not subject to the rules of the Internal Revenue Code applicable to short periods (unless the original year is a short period). However, the years ending and beginning with S's change in status are treated as different tax years (and as short periods) with respect to any item carried to or from these years (e.g., a net operating loss carried under section 172) and with respect to the application of section 481.

(3) Multiple applications. If this paragraph (b) applies more than once with respect to an original year, adjustments must be made in accordance with the principles of this paragraph (b). For example, if S becomes a member of two different consolidated groups during the same original year and ratable allocation is elected with respect to both groups, ratable allocation is generally determined for both groups by treating the original year as a single tax year; however, if ratable allocation is elected only with respect to the first group, the ratable allocation is determined by treating the original year as a short period that does not include the period that S is a member of the second group. Ratable allocation is not a method of accounting, and ratable allocation with respect to one application of this paragraph (b) to S does not require ratable allocation to be subsequently applied with respect to S.

(C) Extraordinary items. An extraordinary item is—

(1) Any item from the disposition or abandonment of a capital asset as defined in section 1221 (determined without the application of any other rules of law);

(2) Any item from the disposition or abandonment of property used in a trade or business as defined in section 1231(b) (determined without the application of any holding period requirement);

(3) Any item from the disposition or abandonment of an asset described in section 1221(1), (3), (4), or (5), if substantially all the assets in the same category from the same trade or business are disposed of or abandoned in one transaction (or series of related transactions);

(4) Any item from assets disposed of in an applicable asset acquisition under section 1060(c);

(5) Any item carried to or from any portion of the original year (e.g., a net operating loss carried under section 172), and any section 481(a) adjustment;

(6) The effects of any change in accounting method initiated by the filing of the appropriate form after S's change in status;

(7) Any item from the discharge or retirement of indebtedness (e.g., cancellation of indebtedness income or a deduction for retirement at a premium);

(8) Any item from the settlement of a tort or similar third-party liability;

(9) Any compensation-related deduction in connection with S's change in status (including, for example, deductions from bonus, severance, and option cancellation payments made in connection with S's change in status);

(10) Any dividend income from a nonmember that S controls within the meaning of section 304 at the time the dividend is taken into account;

(11) Any deemed income inclusion from a foreign corporation, or any deferred tax amount on an excess distribution from a passive foreign investment company under section 1291;

(12) Any interest expense allocable under section 172(h) to a corporate equity reduction transaction causing this paragraph (b) to apply;

(13) Any credit, to the extent it arises from activities or items that are not ratably allocated (e.g., the rehabilitation credit under section 47, which is based on placement in service); and

(14) Any item which, in the opinion of the Commissioner, would, if ratably allocated, result in a substantial distortion of income in any consolidated return or separate return in which the item is included.

(D) Election—(1) Statement. The election to ratably allocate items under this paragraph (b)(2)(ii) must be made in a separate statement entitled, “THIS IS AN ELECTION UNDER § 1.1502-76(b)(2)(ii) TO RATABLY ALLOCATE THE YEAR'S ITEMS OF [INSERT NAME AND EMPLOYER IDENTIFICATION NUMBER OF THE MEMBER].” The election must be filed by including a statement on or with the returns including the items for the years ending and beginning with S's change in status. If two or more members of the same consolidated group, as a consequence of the same plan or arrangement, cease to be members of that group and remain affiliated as members of another consolidated group, an election under this paragraph (b)(2)(ii)(D)(1) may be made only if it is made by each such member. Each statement must also indicate that an agreement, as described in paragraph (b)(2)(ii)(D)(2) of this section, has been entered into. Each party signing the agreement must retain either the original or a copy of the agreement as part of its records. See § 1.6001-1(e).

(2) Agreement. For each election under this paragraph (b)(2)(ii), the member and the common parent of each affected group must sign and date an agreement. The agreement must—

(i) Identify the extraordinary items, their amounts, and the separate or consolidated returns in which they are included;

(ii) Identify the aggregate amount to be ratably allocated, and the portion of the amount included in the separate and consolidated returns; and

(iii) Include the name and employer identification number of the common parent (if any) of each group that must take the items into account.

(iii) Ratable allocation of a month's items. If ratable allocation under paragraph (b)(2)(ii) of this section is not elected (e.g., because S is required to change its annual accounting period), this paragraph (b)(2)(iii) may be applied to ratably allocate only S's items taken into account in the month of its change in status, but only if the allocation is consistently applied by all affected persons. The ratable allocation is made by applying the principles of paragraph (b)(2)(ii) of this section under any reasonable method. For example, S may close its books both at the end of the preceding month and at the end of the month of the change, and allocate only its items (other than extraordinary items) from the month of the change. See paragraph (b)(1)(ii)(B) of this section for factors to be considered in determining whether the method is reasonable.

(iv) Taxes. To the extent properly taken into account during the member's tax year (determined without the application of this paragraph (b)), Federal, state, local, and foreign taxes are allocated under paragraph (b)(2) of this section on the basis of the items or activities to which the taxes relate. Thus, income tax is allocated based on the inclusion of the income (determined under the principles of this paragraph (b)) to which the tax relates. For example, if a calendar-year domestic corporation has $100 of foreign source dividend income (determined in accordance with United States tax accounting principles but without taking this paragraph (b) into account) that is passive income for purposes of section 904, and $60 of the income is allocated under this paragraph (b) to the period of the calendar year after it becomes a member of a consolidated group, then 60% of the corporation's deemed paid foreign tax credit associated with its dividend income for the calendar year is taken into account in computing the group's passive basket consolidated foreign tax credit. Similarly, property taxes relate to the ownership of property and are allocated over the period that the property is owned. This paragraph (b)(2)(iv) applies without regard to any determination or allocation by another taxing jurisdiction.

(v) Acquisition of S corporation. If a corporation is acquired in a transaction to which paragraph (b)(1)(ii)(A)(2) of this section applies, then paragraphs (b)(2)(ii) and (iii) of this section do not apply and items of income, gain, loss, deduction, and credit are assigned to each short taxable year on the basis of the corporation's normal method of accounting as determined under section 446. This paragraph (b)(2)(v) applies to transactions occurring after November 10, 1999.

(vi) Passthrough entities—(A) In general. If S is a partner in a partnership or an owner of a similar interest with respect to which items of the entity are taken into account by S, S is treated, solely for purposes of determining the year to which the entity's items are allocated under paragraph (b)(2) of this section, as selling or exchanging its entire interest in the entity immediately before S's change in status.

(B) Treatment as a conduit. For purposes of this paragraph (b)(2), if a member (together with other members) would be treated under section 318(a)(2) as owning an aggregate of at least 50% of any stock owned by the passthrough entity, the method that is used to determine the inclusion of the entity's items in the consolidated or separate return must be the same method that is used to determine the inclusion of the member's items in the consolidated or separate return.

(C) Exception for certain foreign entities. This paragraph (b)(2)(v) does not apply to any foreign corporation generating the deemed inclusion of income, or to any passive foreign investment company generating a deferred tax amount on an excess distribution under section 1291.

(3) Anti-avoidance rule. If any person acts with a principal purpose contrary to the purposes of this paragraph (b), to substantially reduce the Federal income tax liability of any person, adjustments must be made as necessary to carry out the purposes of this section.

(4) Determination of due date for separate return. Paragraph (c) of this section contains rules for the filing of the separate return referred to in this paragraph (b). In applying paragraph (c) of this section, the due date for the filing of S's separate return shall also be determined without regard to the ending of the tax year under paragraph (b)(1)(ii) of this section or the deemed cessation of its existence under paragraph (b)(2)(i) of this section.

(5) Examples. For purposes of the examples in this paragraph (b), unless otherwise stated, P and X are common parents of calendar-year consolidated groups, P owns all of the only class of T's stock, T owns no stock of lower-tier members, all persons use the accrual method of accounting, the facts set forth the only corporate activity, all transactions are between unrelated persons, tax liabilities are disregarded, and any election required under paragraph (b)(2) of this section is properly made. The principles of this paragraph (b) are illustrated by the following examples.

(6) Effective date—(i) General rule. Except as provided in paragraphs (b)(1)(ii) (A)(2) and (b)(2)(v) of this section, this paragraph (b) applies to corporations becoming or ceasing to be members of consolidated groups on or after January 1, 1995.

(ii) Prior law. For prior transactions, see prior regulations under section 1502 as in effect with respect to the transaction. See, e.g., § 1.1502-76(b) and (d) as contained in the 26 CFR part 1 edition revised as of April 1, 1994. However, § 1.1502-76(b)(5) and (6) as contained in the 26 CFR part 1 edition revised as of April 1, 1994 do not apply with respect to corporations becoming or ceasing to be members of consolidated groups on or after January 1, 1995. If both this paragraph (b) and prior law may apply to determine the inclusion of any amount in a return, appropriate adjustments must be made to prevent the omission or duplication of the amount.

(c) Time for making separate returns for periods not included in consolidated return—(1) Consolidated return filed by due date for separate return. If the group has filed a consolidated return on or before the due date for the filing of a subsidiary's separate return (including extensions of time and determined without regard to any change of its taxable year required under paragraph (a) of this section), then the separate return for any portion of the subsidiary's taxable year for which its income is not included in the consolidated return of the group must be filed no later than the due date of such consolidated return (including extensions of time).

(2) Consolidated return not filed by due date for separate return. If the group has not filed a consolidated return on or before the due date for the filing of a subsidiary corporation's separate return (including extensions of time and determined without regard to any change of its taxable year required under paragraph (a) of this section), then on or before such due date such subsidiary shall file a separate return either for the portion of its taxable year for which its income would not be included in a consolidated return if such a return were filed, or for its complete taxable year. However, if a separate return is filed for such portion of its taxable year and the group subsequently does not file a consolidated return, such subsidiary corporation shall file a substituted return for its complete taxable year not later than the due date (including extensions of time) prescribed for the filing of the common parent's return. On the other hand, if the return is filed for the subsidiary's complete taxable year and the group later files a consolidated return, such subsidiary must file an amended return not later than the due date (including extensions of time) for the filing of the consolidated return of the group. Such amended return shall be for that portion of such subsidiary's taxable year which is not included in the consolidated return. If, under this subparagraph, a substituted return must be filed, then the return previously filed shall not be considered a return within the meaning of section 6011. If, under this subparagraph, a substituted or amended return must be filed, then, for purposes of sections 6513(a) and 6601(a), the last date prescribed for payment of tax shall be the due date (not including extensions of time) for the filing of the subsidiary's separate return (determined without regard to this subparagraph and without regard to any change of its taxable year required under paragraph (a) of this section).

(3) Examples. The provisions of this paragraph may be illustrated by the following examples:

(d) Effective/applicability date—(1) Taxable years of members of group effective date. (i) In general. Paragraph (a) of this section applies to any original consolidated Federal income tax return due (without extensions) after July 20, 2007.

(ii) Prior law. For original consolidated Federal income tax returns due (without extensions) after April 25, 2006, and on or before July 20, 2007, see § 1.1502-76T as contained in 26 CFR part 1 in effect on April 1, 2007. For original consolidated Federal income tax returns due (without extensions) on or before April 25, 2006, see § 1.1502-76 as contained in 26 CFR part 1 in effect on April 1, 2006.

(2) Election to ratably allocate items effective date—(i) In general. Paragraph (b)(2)(ii)(D) of this section applies to any original consolidated Federal income tax return due (without extensions) after July 20, 2007.

(ii) Prior law. For original consolidated Federal income tax returns due (without extensions) after May 30, 2006, and on or before July 20, 2007, see § 1.1502-76T as contained in 26 CFR part 1 in effect on April 1, 2007. For original consolidated Federal income tax returns due (without extensions) on or before May 30, 2006, see § 1.1502-76 as contained in 26 CFR part 1 in effect on April 1, 2006.
