§ 1.1502-76 Taxable year of members of group.

(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 will, 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 must be requested at the time and in the manner that the Commissioner of Internal Revenue may prescribe by Internal Revenue Service forms and instructions or by publication in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii) of this chapter).

(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.

(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.

(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.

Example 1. Items allocated between consolidated and separate returns.(a) Facts. P and S are the only members of the P group. P sells all of S's stock to individual A on June 30, and therefore S becomes a nonmember on July 1 of Year 2.

(b) Analysis. Under paragraph (b)(1) of this section, the P group's consolidated return for Year 2 includes P's income for the entire tax year and S's income for the period from January 1 to June 30, and S must file a separate return for the period from July 1 to December 31.

(c) Acquisition of another subsidiary before end of tax year. The facts are the same as in paragraph (a) of this Example 1, except that on July 31 P acquires all the stock of T (which filed a separate return for its year ending on November 30 of Year 1) and T therefore becomes a member on August 1 of Year 2. Under § 1.1502-75(d) and paragraph (b)(1) of this section, the P group's consolidated return for Year 2 includes P's income for the entire year, S's income from January 1 to June 30, and T's income from August 1 to December 31. S must file a separate return that includes its income from July 1 to December 31, and T must file a separate return that includes its income from December 1 of Year 1 to July 31 of Year 2. (If P had acquired T after December 31, the P group that included S is a different group from the P group that includes T, and, for example, the P group that includes T must make a separate election under section 1501 and § 1.1502-75 if consolidated returns are to be filed.)

Example 2. Group structure change.(a) Facts. P owns all of the stock of S and T. Shortly after the beginning of Year 1, P merges into T in a reorganization described in section 368(a)(1)(A) (and in section 368(a)(1)(D)), and P's shareholders receive T's stock in exchange for all of P's stock. The P group is treated under § 1.1502-75(d)(2)(ii) as remaining in existence with T as its common parent.

(b) Analysis. Under paragraph (b)(1) of this section, the P group's return must include the common parent's items for the entire consolidated return year and, if the common parent ceases to be the common parent but the group remains in existence, appropriate adjustments must be made. Consequently, although P did not exist for all of Year 1, P's items for the portion of Year 1 ending with the merger are treated as the items of the common parent that must be included in the P group's return for Year 1.

(c) Reverse acquisition. Assume instead that X acquires all of P's assets in exchange for more than 50% of X's stock in a reorganization described in section 368(a)(1)(D). The reorganization constitutes a reverse acquisition under § 1.1502-75(d)(3), with the X group terminating and the P group surviving with X as its common parent. Consequently, P's items for the portion of Year 1 ending with the acquisition are treated as the items of the common parent that must be included in the P group's return for Year 1, and X's items are treated for purposes of paragraph (b)(1) of this section as the items of a subsidiary included in the P group's return for the portion of Year 1 for which X is a member.

Example 3. Ratable allocation.(a) Facts. P sells all of T's stock to X, and T becomes a nonmember on July 1 of Year 1. T engages in the production and sale of merchandise throughout Year 1 and is required to use inventories. The sale is treated as causing T's tax year to end on June 30, and the periods beginning and ending with the sale are treated as two tax years for Federal income tax purposes.

(b) Analysis. If ratable allocation under paragraph (b)(2)(ii) of this section is not elected, T must perform an inventory valuation as of the acquisition and also as of the end of Year 1. If ratable allocation is elected, T must perform an inventory valuation only as of the close of Year 1, and T's income from inventory is ratably allocated, along with T's other items that are not extraordinary items, between the P and X consolidated returns.

(c) Merger into nonmember. Assume instead that T merges into a wholly owned subsidiary of X in a reorganization described in section 368(a)(2)(D), and P receives 10% of X's stock in exchange for all of T's stock. Under paragraph (b)(2)(ii)(B) of this section, because T's tax year ends on June 30 under section 381(b)(1), T's original year determined without taking paragraph (b) of this section into account also ends on June 30. Consequently, a ratable allocation under paragraph (b)(2)(ii) of this section is the same as an allocation based on closing the books.

Example 4. Net operating loss.P sells all of T's stock to X, T becomes a nonmember on June 30 of Year 1, and ratable allocation under paragraph (b)(2)(ii) of this section is elected. Under ratable allocation, the X group has a $100 consolidated net operating loss for Year 1, all of which is attributable to T. However, because of extraordinary items, T has $100 of income for the portion of Year 1 that T is a member of the P group. Under paragraph (b)(2)(ii)(B)(2) of this section, T's loss may be carried back from the X group to the portion of Year 1 that T was a member of the P group. See also section 172 and § 1.1502-21(b). Under paragraph (b)(2)(ii)(C)(5) of this section, any item carried to or from any portion of the original year is an extraordinary item, and the loss therefore is not taken into account again in determining the ratable allocation under paragraph (b)(2)(ii) of this section. Example 5. Employee benefit plans.(a) Facts. P sells all of T's stock to X, and T becomes a nonmember on June 30 of Year 1. On March 15 of Year 2, T contributes $100 to its retirement plan, which is a qualified plan under section 401(a). T is not required to make quarterly contributions to the plan for Year 1 under section 412(m). The contribution is made on account of T's taxable period beginning on July 1 of Year 1, and is deemed in accordance with section 404(a)(6) to have been made on the last day of T's taxable period beginning on July 1 of Year 1. Ratable allocation under paragraph (b)(2)(ii) of this section is not elected.

(b) Analysis. Under paragraph (b) of this section, the sale is treated as causing T's tax year to end on June 30, and the period beginning on July 1 is treated as a separate annual accounting period for all Federal income tax purposes. T's income from January 1 to June 30 is included in the P group's Year 1 return, and T's income from July 1 to December 31 is included in the X group's Year 1 return. Thus, the $100 contribution is deductible by T for the period of Year 1 that it is a member of the X group, subject to the applicable limitations of section 404, if a contribution on the last day of that period would otherwise be deductible.

(c) The facts are the same as in paragraph (a) of this Example 5, except that, in accordance with section 404(a)(6), $40 of the $100 contribution is made on account of T's taxable period beginning on January 1 of Year 1 and is deemed to be made on the last day of T's taxable period beginning on January 1 of Year 1. The remaining $60 is made on account of T's taxable period beginning on July 1 of Year 1 and is deemed to be made on the last day of T's taxable period beginning on July 1 of Year 1. As in paragraph (b) of this Example 5, under paragraph (b) of this section, the sale is treated as causing T's tax year to end on June 30, and the period beginning on July 1 is treated as a separate annual accounting period for all Federal income tax purposes. The $40 portion of the contribution is deductible by T for the period of Year 1 that it is a member of the P group, subject to the applicable limitations of section 404 and provided that a $40 contribution on the last day of that period would otherwise be deductible for that period, and the $60 portion is deductible by T for the period of Year 1 that it is a member of the X group, subject to the same conditions.

(d) Ratable allocation. The facts are the same as in paragraph (a) of this Example 5, except that P, T, and X elect ratable allocation under paragraph (b)(2)(ii) of this section and T's deduction for the retirement plan contribution is not an extraordinary item. T's deduction may be ratably allocated, subject to the applicable limitations of section 404, and is allowable only if a contribution on the last day of Year 1 otherwise would be deductible for any period in the year. (The results would be the same if S were an unaffiliated corporation when acquired by X, and the due date of its last separate return (including extensions) were before the pension contribution was made on March 15 of Year 2.)

Example 6. Allocation of partnership items.(a) Facts. P sells all of T's stock to X, and T becomes a nonmember on June 30 of Year 1. T has a 10% interest in the capital and profits of a calendar-year partnership.

(b) Analysis. Under paragraph (b)(2)(vi)(A) of this section, T is treated, solely for purposes of determining T's tax year in which the partnership's items are included, as selling or exchanging its entire interest in the partnership as of P's sale of T's stock. Thus, the deemed disposition is not taken into account under section 708, it does not result in gain or loss being recognized by T, and T's holding period is unaffected. However, under section 706(a), in determining T's income, T is required to include its distributive share of partnership items for the partnership's year ending within or with T's tax year. Under section 706(c)(2), the partnership's tax year is treated as closing with respect to T for this purpose as of P's sale of T's stock. The allocation of T's distributive share of partnership items must be made under § 1.706-1(c)(2)(ii).

(c) Controlled partnership. The facts are the same as in paragraph (a) of this Example 6, except that T has a 75% interest in the capital and profits of the partnership. Under paragraph (b)(2)(vi)(B) of this section, T's distributive share of the partnership items is treated as T's items for purposes of paragraph (b)(2) of this section. Thus, if ratable allocation under paragraph (b)(2)(ii) of this section is not elected, T's distributive share of the partnership's items must be determined under § 1.706-1(c)(2)(ii) by an interim closing of the partnership's books. Similarly, if ratable allocation is elected for T's items that are not extraordinary items, T's distributive share of the partnership's nonextraordinary items must also be ratably allocated under § 1.706-1(c)(2)(ii).

Example 7. Acquisition of S corporation.(a) Facts. Z is a small business corporation for which an election under section 1362(a) was in effect at all times since Year 1. At all times, Z had only 100 shares of stock outstanding, all of which were owned by individual A. On July 1 of Year 3, P acquired all of the Z stock. P does not make an election under section 338(g) with respect to its purchase of the Z stock.

(b) Analysis. As a result of P's acquisition of the Z stock, Z's election under section 1362(a) terminates. See sections 1361(b)(1)(B) and 1362(d)(2). Z is required to join in the filing of the P consolidated return. See § 1.1502-75. Z's tax year ends for all Federal income tax purposes on June 30 of Year 3. If no extension of time is sought, Z must file a separate return for the period from January 1 through June 30 of Year 3 on or before March 15 of Year 4. See paragraph (b)(4) of this section. Z will become a member of the P consolidated group as of July 1 of Year 3. See paragraph (b)(1)(ii)(A)(2) of this section. P group's Year 3 consolidated return will include Z's items from July 1 to December 31 of Year 3.

(6) Applicability date. 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.

(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 (c) may be illustrated by the following examples:

(i) Example 1. Corporation P, which filed a separate return for the calendar year 2022, acquires all of the stock of corporation S as of the close of December 31, 2022. Corporation S reports its income on the basis of a fiscal year ending March 31. On July 15, 2023, the due date for the filing of a separate return by S (assuming no extensions of time), a consolidated return has not been filed for the group (P and S). On such date S may either file a return for the period April 1, 2022, through December 31, 2022, or it may file a return for the complete fiscal year ending March 31, 2023. If S files a return for the short period ending December 31, 2022, and if the group elects not to file a consolidated return for the calendar year 2023, S, on or before April 15, 2024 (the due date of P's return, assuming no extensions of time), must file a substituted return for the complete fiscal year ending March 31, 2023, in lieu of the return previously filed for the short period. Interest is computed from July 15, 2023. If, however, S files a return for the complete fiscal year ending March 31, 2023, and the group elects to file a consolidated return for the calendar year 2023, then S must file an amended return covering the period from April 1, 2022, through December 31, 2022, in lieu of the return previously filed for the complete fiscal year. Interest is computed from July 15, 2023.

(ii) Example 2. Assume the same facts as in paragraph (c)(3)(i) of this section (Example 1), except that corporation P acquires all of the stock of corporation S at the close of September 30, 2023, and P files a consolidated return for the group for 2023 on April 15, 2024 (not having obtained any extensions of time). Since a consolidated return has been filed on or before the due date (July 15, 2024) for the filing of the separate return for the taxable year ending March 31, 2024, the return of S for the short taxable year beginning April 1, 2023, and ending September 30, 2023, should be filed no later than April 15, 2024.

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

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