(a) Carryover requirement.

(1) Section 381(c)(1) requires the acquiring corporation to succeed to, and take into account, the net operating loss carryovers of the distributor or transferor corporation. To determine the amount of these carryovers as of the close of the date of distribution or transfer, and to integrate them with any carryovers and carrybacks of the acquiring corporation for purposes of determining the taxable income of the acquiring corporation for taxable years ending after the date of distribution or transfer, it is necessary to apply the provisions of section 172 in accordance with the conditions and limitations of section 381(c)(1) and this section. See also section 382(b) and the regulations thereunder.

(2) The net operating loss carryovers and carrybacks of the acquiring corporation determined as of the close of the date of distribution or transfer shall be computed without reference to any net operating loss of a distributor or transferor corporation. The net operating loss carryovers of a distributor or transferor corporation as of the close of the date of distribution or transfer shall be determined without reference to any net operating loss of the acquiring corporation.

(3) For purposes of the tax imposed under section 56, the acquiring corporation succeeding to and taking into account any net operating loss carryovers of the distributor or transferor corporation shall also succeed to and take into account along with such net operating loss carryforward any deferred tax liability under section 56(b) and the regulations thereunder attributable to such net operating loss carryover.

(b) Carryback of net operating losses. A net operating loss of the acquiring corporation for any taxable year ending after the date of distribution or transfer shall not be carried back in computing the taxable income of a distributor or transferor corporation. However, a net operating loss of the acquiring corporation for any such taxable year shall be carried back in accordance with section 172(b) in computing the taxable income of the acquiring corporation for a taxable year ending on or before the date of distribution or transfer. If a distributor or transferor corporation remains in existence after the date of distribution or transfer, a net operating loss sustained by it for any taxable year beginning after such date shall be carried back in accordance with section 172(b) in computing the taxable income of such corporation for a taxable year ending on or before that date, but may not be carried back or over in computing the taxable income of the acquiring corporation. This paragraph may be illustrated by the following examples:

(c) First taxable year to which carryovers apply.

(1) The net operating loss carryovers available to the distributor or transferor corporation as of the close of the date of distribution or transfer shall first be carried to the first taxable year of the acquiring corporation ending after that date. This rule applies irrespective of whether the date of distribution or transfer is on the last day, or any other day, of the acquiring corporation's taxable year. Thus, such net operating loss carryovers shall first be used by the acquiring corporation with respect to the computation of its net operating loss deduction under section 172(a), and its taxable income determined under the provisions of section 172(b)(2), for such first taxable year. However, see paragraph (f) of this section.

(2) The net operating loss carryovers available to the distributor or transferor corporation as of the close of the date of distribution or transfer shall be carried to the acquiring corporation without diminution by reason of the fact that the acquiring corporation does not acquire 100 percent of the assets of the distributor or transferor corporation. Thus, if a parent corporation owning 80 percent of all classes of stock of its subsidiary corporation were to acquire its share of the assets of the subsidiary corporation upon a complete liquidation described in paragraph (b)(1)(i) of §1.381(a)-1, then, subject to the conditions and limitations of this section, 100 percent of the net operating loss carryovers available to the subsidiary corporation as of the close of the date of distribution would be carried over to the parent corporation.

(d) Limitation on net operating loss deduction for first taxable year ending after date of distribution or transfer.

(1) That part of the acquiring corporation's net operating loss deduction, determined in accordance with sections 172(a) and 381(c)(1), for its first taxable year ending after the date of distribution or transfer which is attributable to the net operating loss carryovers of the distributor or transferor corporation, is limited by section 381(c)(1)(B) and this paragraph to an amount equal to the acquiring corporation's postacquisition part year taxable income. Such postacquisition part year taxable income is the amount which bears the same ratio to the acquiring corporation's taxable income for the first taxable year ending after the date of distribution or transfer (determined under section 63 without regard to any net operating loss deduction but taking into account other items to which the acquiring corporation succeeds under section 381) as the number of days in such first taxable year which follow the date of distribution or transfer bears to the total number of days in such taxable year. Thus, if the date of distribution or transfer is the last day of the acquiring corporation's taxable year, the net operating loss carryovers of the distributor or transferor are allowed in full in computing under section 172(a) the net operating loss deduction of the acquiring corporation for its first taxable year ending after that date. In such instance, the number of days in the first taxable year which follow the date of distribution or transfer is the total number of days in such taxable year.

(2) The limitation provided by section 381(c)(1)(B) applies solely for the purpose of computing the net operating loss deduction of the acquiring corporation under section 172(a) for the acquiring corporation's first taxable year ending after the date of distribution or transfer. The limitation does not apply for purposes of determining the portion of any net operating loss (whether of the distributor, transferor, or acquiring corporation) which may be carried to any taxable year of the acquiring corporation following its first taxable year ending after the date of distribution or transfer since such determination is made pursuant to section 172(b) and section 381(c)(1)(C). See paragraphs (e) and (f) of this section.

(3) The limitation provided by section 381(c)(1)(B) shall be applied to the aggregate of the allowable net operating loss carryovers of the distributor or transferor corporation without reference to the taxable years in which the net operating losses were sustained by such corporation. If the acquiring corporation has acquired the assets of two or more distributor or transferor corporations on the same date of distribution or transfer, then the limitation provided by section 381(c)(1)(B) shall be applied to the aggregate of the net operating loss carryovers from all of such distributor or transferor corporations.

(4) If the acquiring corporation succeeds to the net operating loss carryovers of two or more distributor or transferor corporations on two or more different dates of distribution or transfer within one taxable year of the acquiring corporation, the limitation to be applied under section 381(c)(1)(B) to the aggregate of such carryovers shall be governed by the rules prescribed in paragraph (b) of §1.381(c)(1)-2.

(5) Illustrations. The application of this paragraph may be illustrated by the following examples:

(e) Computation of carryovers and carrybacks; general rule—(1) Sequence for applying losses and computation of taxable income. The portion of any net operating loss which is carried back or carried over to any taxable year is the excess, if any, of the amount of the loss over the sum of the taxable income for each of the prior taxable years to which the loss may be carried under sections 172(b)(1) and 381. In determining the taxable income for each such prior taxable year for this purpose, the various net operating loss carryovers and carrybacks to such prior taxable year are considered to be applied in reduction of the taxable income in the order of the taxable years in which the net operating losses are sustained, beginning with the loss for the earliest taxable year. The application of this rule to the taxable income of the acquiring corporation for any taxable year ending after the date of distribution or transfer involves the use of carryovers of the distributor or transfer corporation, and of carryovers and carrybacks of the acquiring corporation. In such instance, the sequence for the use of loss years remains the same, and the requirement is to begin with the net operating loss of the earliest taxable year, whether or not it is a loss of the distributor, transferor, or acquiring corporation. The taxable income of the acquiring corporation for any taxable year ending after the date of distribution or transfer shall be determined in the manner prescribed by section 172(b)(2), except that, if the date of distribution or transfer is on a day other than the last day of a taxable year of the acquiring corporation, the taxable income of such corporation for the taxable year which includes such date shall be computed in the special manner prescribed by section 381(c)(1)(C) and paragraph (f) of this section.

(2) Loss year of transferor or distributor considered prior taxable year. Section 381(c)(1)(C) provides that, for the purpose of determining the net operating loss carryovers under section 172(b)(2), a net operating loss for a loss year of a distributor or transferor corporation which ends on or before the last day of a loss year of the acquiring corporation shall be considered to be a net operating loss for a year prior to such loss year of the acquiring corporation. In a case where the acquiring corporation has acquired the assets of two or more distributor or transferor corporations on the same date of distribution or transfer, the loss years of the distributor or transferor corporations shall be taken into account in the order in which such loss years terminate; if any one of the loss years of a distributor or transferor corporation ends on the same day as the loss year of another distributor or transferor corporation, either loss year may be taken into account before the other.

(3) Years to which losses may be carried. The taxable years to which a net operating loss shall be carried back or carried over are prescribed by section 172(b)(1). Since the taxable year of the distributor or transferor corporation ends with the close of the date of distribution or transfer, such taxable year and the first taxable year of the acquiring corporation which ends after that date shall be considered two separate taxable years to which a net operating loss of the distributor or transferor corporation for any taxable year ending before that date may be carried over. This rule applies even though the taxable year of the distributor or transferor corporation which ends on the date of distribution or transfer is a period of less than twelve months. However, for the purpose of determining under section 172(b)(1) the taxable years to which a net operating loss of the acquiring corporation is carried over or carried back, the first taxable year of the acquiring corporation which ends after the date of distribution or transfer shall be treated as only one taxable year even though such taxable year is considered under section 381(c)(1)(C) and paragraph (f)(2) of this section as two taxable years. The application of this subparagraph may be illustrated by the following example:

(4) Computation of carryovers in a case where the date of distribution or transfer occurs on last day of acquiring corporation's taxable year. The computation of the net operating loss carryovers from the distributor or transferor corporation and from the acquiring corporation in a case where the date of distribution or transfer occurs on the last day of a taxable year of the acquiring corporation may be illustrated by the following example:

(f) Computation of carryovers and carrybacks when date of distribution or transfer is not on last day of acquiring corporation's taxable year—(1) General rule. Pursuant to the provisions of section 381(c)(1)(C), the taxable income of the acquiring corporation for its taxable year which is a prior taxable year for purposes of section 172(b)(2) and paragraph (e) of this section shall be determined in the manner prescribed in this paragraph, if the date of distribution or transfer occurs within, but not on the last day of, such taxable year.

(2) Taxable year considered as two taxable years. Such taxable year of the acquiring corporation shall be considered as though it were two taxable years, but only for the limited purpose of applying section 172(b)(2). The first of such two taxable years shall be referred to in this section as the preacquisition part year; the second, as the postacquisition part year. For purposes of section 172(b)(2), a net operating loss of the acquiring corporation shall be carried to the preacquisition part year and then to the postacquisition part year, whereas a net operating loss of a distributor or transferor corporation shall be carried to the postacquisition part year and then to the acquiring corporation's subsequent taxable years. In determining under section 172(b)(2) and this paragraph the portion of any net operating loss of a distributor or transferor corporation which is carried to any taxable year of the acquiring corporation ending after the postacquisition part year, the taxable income (as determined under this paragraph) of the postacquisition part year shall be taken into account but the taxable income of the preacquisition part year (as so determined) shall not be taken into account. Though considered as two separate taxable years for purposes of section 172(b)(2), the preacquisition part year and the postacquisition part year are treated as one taxable year in determining the years to which a net operating loss is carried under section 172(b)(1). See paragraph (e)(3) of this section.

(3) Preacquisition part year. The preacquisition part year shall begin with the beginning of such taxable year of the acquiring corporation and shall end with the close of the date of distribution or transfer.

(4) Postacquisition part year. The postacquisition part year shall begin with the day following the date of distribution or transfer and shall end with the close of such taxable year of the acquiring corporation.

(5) Division of taxable income. The taxable income for such taxable year (computed with the modifications specified in section 172(b)(2)(A) but without any net operating loss deduction) of the acquiring corporation shall be divided between the preacquisition part year and the postacquisition part year in proportion to the number of days in each. Thus, if in a statutory merger to which section 361 applies Y Corporation acquires the assets of X Corporation on June 30, 1960, and Y Corporation has taxable income (computed in the manner so prescribed) of $36,600 for its calendar year 1960, then the preacquisition part year taxable income would be $18,200 ($36,600 × 182/366) and the postacquisition part year taxable income would be $18,400 ($36,600 × 184/366).

(6) Net operating loss deduction. After obtaining the taxable income of the preacquisition part year and of the postacquisition part year in the manner described in subparagraph (5) of this paragraph, it is necessary to compute the net operating loss deduction for each such part year. This deduction shall be determined in the manner prescribed by section 172(b)(2)(B) but subject to the provisions of this subparagraph. The net operating loss deduction for the preacquisition part year shall, for purposes of section 172(b)(2) only, be determined in the same manner as that prescribed by section 172(b)(2)(B) but shall be computed without taking into account any net operating loss of the distributor or transferor corporation. Therefore, only net operating loss carryovers and carrybacks of the acquiring corporation to the preacquisition part year shall be taken into account in computing the net operating loss deduction for such part year. The net operating loss deduction for the post- acquisition part year shall, for purposes of section 172(b)(2) only, be determined in the same manner as that prescribed by section 172(b)(2)(B) and shall be computed by taking into account all the net operating loss carryovers available to the distributor or transferor corporation as of the close of the date of distribution or transfer, as well as the net operating loss carryovers and carrybacks of the acquiring corporation to the postacquisition part year. The sequence in which the net operating losses of the two corporations shall be applied for purposes of this subparagraph shall be determined in the manner prescribed in paragraph (e) of this section.

(7) Limitation on taxable income. In no case shall the taxable income of the preacquisition part year or the postacquisition part year, as computed under this paragraph, be considered to be less than zero.

(8) Cross reference. If the acquiring corporation succeeds to the net operating loss carryovers of two or more distributors or transferor corporations on two or more dates of distribution or transfer during the same taxable year of the acquiring corporation, the determination of the taxable income of the acquiring corporation for such year pursuant to section 381(c)(1)(C) shall be governed by the rules prescribed in paragraph (c) of §1.381(c)(1)-2.

(9) Illustration. The application of this paragraph may be illustrated by the following example:

(g) Successive acquiring corporations. An acquiring corporation which, in a distribution or transfer to which section 381(a) applies, acquires the assets of a distributor or transferor corporation which previously acquired the assets of another corporation in a transaction to which section 381(a) applies, shall succeed to and take into account, subject to the conditions and limitations of sections 172 and 381, the net operating loss carryovers available to the first acquiring corporation under sections 172 and 381.

(h) Illustration. The application of this section may be further illustrated by the following example:
