(a) Recapture in years beginning after December 31, 1986, of overall foreign losses incurred in taxable years beginning before January 1, 1987—(1) In general. If a taxpayer has a balance in an overall foreign loss account at the end of its last taxable year beginning before January 1, 1987 (pre-effective date years), the amount of that balance shall be recaptured in subsequent years by recharacterizing income received in the income category described in section 904(d) as in effect for taxable years beginning after December 31, 1986 (post-effective date years), that is analogous to the income category for which the overall foreign loss account was established, as follows:

(i) Interest income as defined in section 904(d)(1)(A) as in effect for pre-effective date taxable years is analogous to passive income as defined in section 904(d)(1)(A) as in effect for post-effective date years;

(ii) Dividends from a DISC or former DISC as defined in section 904(d)(1)(B) as in effect for pre-effective date taxable years is analogous to dividends from a DISC or former DISC as defined in section 904(d)(1)(F) as in effect for post-effective date taxable years;

(iii) Taxable income attributable to foreign trade income as defined in section 904(d)(1)(C) as in effect for pre-effective date taxable years is analogous to taxable income attributable to foreign trade income as defined in section 904(d)(1)(G) as in effect for post-effective date years;

(iv) Distributions from a FSC (or former FSC) as defined in section 904(d)(1)(D) as in effect for pre-effective date taxable years is analogous to distributions from a FSC (or former FSC) as defined in section 904(d)(1)(H) as in effect for post-effective date taxable years;

(v) For general limitation income as described in section 904(d)(1)(E) as in effect for pre-effective date taxable years, see the special rule in paragraph (a)(2) of this section.

(2) Rule for general limitation losses—(i) In general. Overall foreign losses incurred in the general limitation category of section 904(d)(1)(E), as in effect for pre-effective date taxable years, that are recaptured in post-effective date taxable years shall be recaptured from the taxpayer's general limitation income, financial services income, shipping income, and dividends from each noncontrolled section 902 corporation. If the sum of the taxpayer's general limitation income, financial services income, shipping income and dividends from each noncontrolled section 902 corporation for a taxable year subject to recapture exceeds the overall foreign loss to be recaptured, then the amount of each type of separate limitation income that will be treated as U.S. source income shall be determined as follows:

This recapture shall be made after the allocation of separate limitation losses pursuant to section 904(f)(5)(B) and before the recharacterization of post-effective date separate limitation income pursuant to section 904(f)(5)(C).

(ii) Exception. If a taxpayer can demonstrate to the satisfaction of the district director that an overall foreign loss in the general limitation category of section 904(d)(1)(E), as in effect for pre-effective date taxable years, is attributable, in sums certain, to losses in one or more separate categories of section 904(d)(1) (including for this purpose the passive income category and the high withholding tax interest category), as in effect for post-effective date taxable years, then the taxpayer may recapture the loss (in the amounts demonstrated) from those separate categories only.

(3) Priority of recapture of overall foreign losses incurred in pre-effective date taxable years. An overall foreign loss incurred by a taxpayer in pre-effective date taxable years shall be recaptured to the extent thereof before the taxpayer recaptures an overall foreign loss incurred in a post-effective date taxable year.

(4) Examples. The following examples illustrate the application of this paragraph (a).

(b) Treatment of overall foreign losses that are part of net operating losses incurred in pre-effective date taxable years which are carried forward to post-effective date taxable years—(1) Rule. An overall foreign loss that is part of a net operating loss incurred in a pre-effective date taxable year which is carried forward, pursuant to section 172, to a post-effective date taxable year will be carried forward under the rules of section 904(f)(5) and the regulations under that section. See also Notice 89-3, 1989-1 C.B. 623. For this purpose the loss must be allocated to income in the category analogous to the income category set forth in section 904(d) as in effect for pre-effective date taxable years in which the loss occurred. The analogous category shall be determined under the rules of paragraph (a) of this section.

(2) Example. The following example illustrates the rule of paragraph (b)(1) of this section.

(c) Treatment of overall foreign losses that are part of net operating losses incurred in post-effective date taxable years which are carried back to pre-effective date taxable years—(1) Allocation to analogous income category. An overall foreign loss that is part of a net operating loss incurred by the taxpayer in a post-effective date taxable year which is carried back, pursuant to section 172, to a pre-effective date taxable year shall be allocated first to income in the pre-effective date income category analogous to the income category set forth in section 904(d) as in effect for post-effective date taxable years in which the loss occurred. Except for the general limitation income category, the pre-effective date income category that is analogous to a post-effective date income category shall be determined under paragraphs (a)(1) (i) through (iv) of this section. The general limitation income category for pre-effective date years shall be treated as the income category that is analogous to the post-effective date categories for general limitation income, financial services income, shipping income, dividends from each noncontrolled section 902 corporation and high withholding tax interest income. If the net operating loss resulted from separate limitation losses in more than one post-effective date income category and more than one loss is carried back to pre-effective date general limitation income, then the losses shall be allocated to the pre-effective date general limitation income based on the following formula:

(2) Allocation to U.S. source income. If an overall foreign loss is carried back to a pre-effective date taxable year and the loss exceeds the foreign source income in the analogous category for the carry back year, the remaining loss shall be allocated against U.S. source income as set forth in §1.904(f)-3. The amount of the loss that offsets U.S. source income must be added to the taxpayer's overall foreign loss account. An addition to an overall foreign loss account resulting from the carry back of a net operating loss incurred by a taxpayer in a post-effective date taxable year shall be treated as having been incurred by the taxpayer in the year in which the loss arose and shall be subject to recapture pursuant to section 904(f) as in effect for post-effective date taxable years.

(3) Allocation to other separate limitation categories. To the extent that an overall foreign loss that is carried back as part of a net operating loss exceeds the separate limitation income to which it is allocated and the U.S. source income of the taxpayer for the taxable year to which the loss is carried, the loss shall be allocated pro rata to other separate limitation income of the taxpayer for the taxable year. However, there shall be no recharacterization of separate limitation income pursuant to section 904(f)(5) as a result of the alloction of such a net operating loss to other separate limitation income of the taxpayer.

(4) Examples. The following examples illustrate the rules of paragraph (c) of this section.

(d) Recapture of FORI and general limitation overall foreign losses incurred in taxable years beginning before January 1, 1983. For taxable years beginning after December 31, 1986, and before January 1, 1991, the rules set forth in §1.904 (f)-6 shall apply for purposes of recapturing general limitation and foreign oil related income (FORI) overall foreign losses incurred in taxable years beginning before January 1, 1983 (pre-1983). For taxable years beginning after December 31, 1990, the rules set forth in this section shall apply for purposes of recapturing pre-1983 general limitation and FORI overall foreign losses.

(e) Recapture of pre-1983 overall foreign losses determined on a combined basis. The rules set forth in paragraph (a)(2) of this section shall apply for purposes of recapturing overall foreign losses incurred in taxable years beginning before January 1, 1983, that were computed on a combined basis in accordance with §1.904 (f)-1(c) (1).

(f) Transition rules for taxable years beginning before December 31, 1990. For transition rules for taxable years beginning before January 1, 1990, see 26 CFR 1.904 (f)-13T as it appeared in the Code of Federal Regulations revised as of April 1, 1990.

(g) Recapture in years beginning after December 31, 2002, of separate limitation losses and overall foreign losses incurred in years beginning before January 1, 2003, with respect to the separate category for dividends from a noncontrolled section 902 corporation—(1) Recapture of separate limitation loss or overall foreign loss in a separate category for dividends from a noncontrolled section 902 corporation. To the extent that a taxpayer has a balance in any separate limitation loss or overall foreign loss account in a separate category for dividends from a noncontrolled section 902 corporation under section 904(d)(1)(E) (prior to its repeal by Public Law 108-357, 118 Stat. 1418 (October 22, 2004)) at the end of the taxpayer's last taxable year beginning before January 1, 2003 (or a later taxable year in which the taxpayer received a dividend subject to a separate limitation for dividends from that noncontrolled section 902 corporation), the amount of such balance shall be allocated on the first day of the taxpayer's next taxable year to the taxpayer's other separate categories. The amount of such balance shall be allocated in the same percentages as the taxpayer properly characterized the stock of the noncontrolled section 902 corporation for purposes of apportioning the taxpayer's interest expense for its first taxable year ending after the first day of such corporation's first taxable year beginning after December 31, 2002, under §1.861-12T(c)(3) or §1.861-12(c)(4), as the case may be. To the extent a taxpayer has a balance in any separate limitation loss account in a separate category for dividends from a noncontrolled section 902 corporation with respect to another separate category, and the separate limitation loss would otherwise be assigned to that other category under this paragraph (g)(1), such balance shall be eliminated.

(2) Recapture of separate limitation loss in another separate category. To the extent that a taxpayer has a balance in any separate limitation loss account in a separate category with respect to a separate category for dividends from a noncontrolled section 902 corporation under section 904(d)(1)(E) (prior to its repeal by Public Law 108-357, 118 Stat. 1418 (October 22, 2004)) at the end of the taxpayer's last taxable year with or within which ends the last taxable year of the noncontrolled section 902 corporation beginning before January 1, 2003, such loss shall be recaptured in subsequent taxable years as income in the appropriate separate categories. The separate limitation loss shall be recaptured as income in other separate categories in the same percentages as the taxpayer properly characterizes the stock of the noncontrolled section 902 corporation for purposes of apportioning the taxpayer's interest expense in its first taxable year ending after the first day of the foreign corporation's first taxable year beginning after December 31, 2002, under §1.861-12T(c)(3) or §1.861-12(c)(4), as the case may be. To the extent a taxpayer has a balance in a separate limitation loss account in a separate category that would have been recaptured as income in that same category under this paragraph (g)(2), such balance shall be eliminated.

(3) Exception. Where a taxpayer formerly met the stock ownership requirements of section 902(a) with respect to a foreign corporation, but did not meet the requirements of section 902(a) on December 20, 2002 (or on the first day of the taxpayer's first taxable year beginning after December 31, 2002, in the case of a transaction that was the subject of a binding contract in effect on December 20, 2002), if the taxpayer has a balance in any separate limitation loss or overall foreign loss account for a separate category for dividends from that foreign corporation under section 904(d)(1)(E) (prior to its repeal by Public Law 108-357, 118 Stat. 1418 (October 22, 2004)) at the end of the taxpayer's last taxable year beginning before January 1, 2003, then the amount of such balance shall not be subject to recapture under section 904(f) and this section. If a separate limitation loss or overall foreign loss account for such category is not subject to recapture under this paragraph (g)(3), the taxpayer cannot carry over any unused foreign taxes in such separate category to any other limitation category. However, a taxpayer may elect to recapture the balances of all separate limitation loss and overall foreign loss accounts for all separate categories for dividends from such formerly-owned noncontrolled section 902 corporations under the rules of paragraphs (g)(1) and (2) of this section. If a taxpayer so elects, it may carry over any unused foreign taxes in these separate categories to the appropriate separate categories as provided in §1.904-2(h).

(4) Examples. The following examples illustrate the application of this paragraph (g):

(5) Effective/applicability date. This paragraph (g) applies to taxable years ending on or after April 20, 2009. See 26 CFR 1.904(f)-12T(g) (revised as of April 1, 2009) for rules applicable to taxable years beginning after December 31, 2002, and ending before April 20, 2009.

(h) Recapture in years beginning after December 31, 2006, of separate limitation losses and overall foreign losses incurred in years beginning before January 1, 2007—(1) Losses related to pre-2007 separate categories for passive income, certain dividends from a DISC or former DISC, taxable income attributable to certain foreign trade income or certain distributions from a FSC or former FSC—(i) Recapture of separate limitation loss or overall foreign loss incurred in a pre-2007 separate category for passive income, certain dividends from a DISC or former DISC, taxable income attributable to certain foreign trade income or certain distributions from a FSC or former FSC. To the extent that a taxpayer has a balance in any separate limitation loss or overall foreign loss account in a pre-2007 separate category (as defined in §1.904-7(g)(1)(ii)) for passive income, certain dividends from a DISC or former DISC, taxable income attributable to certain foreign trade income or certain distributions from a FSC or former FSC, at the end of the taxpayer's last taxable year beginning before January 1, 2007, the amount of such balance, or balances, shall be allocated on the first day of the taxpayer's next taxable year to the taxpayer's post-2006 separate category (as defined in §1.904-7(g)(1)(iii)) for passive category income.

(ii) Recapture of separate limitation loss with respect to a pre-2007 separate category for passive income, certain dividends from a DISC or former DISC, taxable income attributable to certain foreign trade income or certain distributions from a FSC or former FSC. To the extent that a taxpayer has a balance in any separate limitation loss account in any pre-2007 separate category with respect to a pre-2007 separate category for passive income, certain dividends from a DISC or former DISC, taxable income attributable to certain foreign trade income or certain distributions from a FSC or former FSC at the end of the taxpayer's last taxable year beginning before January 1, 2007, such loss shall be recaptured in subsequent taxable years as income in the post-2006 separate category for passive category income.

(2) Losses related to pre-2007 separate categories for shipping, financial services income or general limitation income—(i) Recapture of separate limitation loss or overall foreign loss incurred in a pre-2007 separate category for shipping income, financial services income or general limitation income. To the extent that a taxpayer has a balance in any separate limitation loss or overall foreign loss account in a pre-2007 separate category for shipping income, financial services income or general limitation income at the end of the taxpayer's last taxable year beginning before January 1, 2007, the amount of such balance, or balances, shall be allocated on the first day of the taxpayer's next taxable year to the taxpayer's post-2006 separate category for general category income.

(ii) Recapture of separate limitation loss with respect to a pre-2007 separate category for shipping income, financial services income or general limitation income. To the extent that a taxpayer has a balance in any separate limitation loss account in any pre-2007 separate category with respect to a pre-2007 separate category for shipping income, financial services income or general limitation income at the end of the taxpayer's last taxable year beginning before January 1, 2007, such loss shall be recaptured in subsequent taxable years as income in the post-2006 separate category for general category income.

(3) Losses related to a pre-2007 separate category for high withholding tax interest—(i) Recapture of separate limitation loss or overall foreign loss incurred in a pre-2007 separate category for high withholding tax interest. To the extent that a taxpayer has a balance in any separate limitation loss or overall foreign loss account in a pre-2007 separate category for high withholding tax interest at the end of the taxpayer's last taxable year beginning before January 1, 2007, the amount of such balance shall be allocated on the first day of the taxpayer's next taxable year on a pro rata basis to the taxpayer's post-2006 separate categories for general category and passive category income, based on the proportion in which any unused foreign taxes in the same pre-2007 separate category for high withholding tax interest are allocated under §1.904-2(i)(1). If the taxpayer, other than a financial services entity as defined in §1.904-4(e)(3), has no unused foreign taxes in the pre-2007 separate category for high withholding tax interest, then any loss account balance in that category shall be allocated to the post-2006 separate category for passive category income. If the taxpayer is a financial services entity, as defined in §1.904-4(e)(3), and has no unused foreign taxes in the pre-2007 separate category for high withholding tax interest, then any loss account balance in that category shall be allocated to the post-2006 separate category for general category income.

(ii) Recapture of separate limitation loss with respect to a pre-2007 separate category for high withholding tax interest. To the extent that a taxpayer has a balance in a separate limitation loss account in any pre-2007 separate category with respect to a pre-2007 separate category for high withholding tax interest at the end of the taxpayer's last taxable year beginning before January 1, 2007, such loss shall be recaptured in subsequent taxable years on a pro rata basis as income in the post-2006 separate categories for general category and passive category income, based on the proportion in which any unused foreign taxes in the pre-2007 separate category for high withholding tax interest are allocated under §1.904-2(i)(1). If the taxpayer, other than a financial services entity as defined in §1.904-4(e)(3), has no unused foreign taxes in the pre-2007 separate category for high withholding tax interest, then the loss account balance shall be recaptured in subsequent taxable years solely as income in the post-2006 separate category for passive category income. If the taxpayer is a financial services entity, as defined in §1.904-4(e)(3), and has no unused foreign taxes in the pre-2007 separate category for high withholding tax interest, then the loss account balance shall be recaptured in subsequent taxable years solely as income in the post-2006 separate category for general category income.

(4) Elimination of certain separate limitation loss accounts. After application of paragraphs (h)(1) through (h)(3) of this section, any separate limitation loss account allocated to the post-2006 separate category for passive category income for which income is to be recaptured as passive category income, as determined under those same provisions, shall be eliminated. Similarly, after application of paragraphs (h)(1) through (h)(3) of this section, any separate limitation loss account allocated to the post-2006 separate category for general category income for which income is to be recaptured as general category income, as determined under those same provisions, shall be eliminated.

(5) Alternative method. In lieu of applying the rules of paragraphs (h)(1) through (h)(3) of this section, a taxpayer may apply the principles of paragraphs (g)(1) and (g)(2) of this section to determine recapture in taxable years beginning after December 31, 2006, of separate limitation losses and overall foreign losses incurred in taxable years beginning before January 1, 2007. A taxpayer may choose to use the alternative method on a timely filed (original or amended) tax return or during an audit. A taxpayer that uses the alternative method on an amended return or in the course of an audit must make appropriate adjustments to eliminate any double benefit arising from application of the alternative method to years that are not open for assessment. A taxpayer's choice to use the alternative method is evidenced by employing the method. The taxpayer need not file any separate statement.

(6) Effective/applicability date. This paragraph (h) shall apply to taxable years beginning after December 31, 2006, and ending on or after December 21, 2007. However, taxpayers may choose to apply 26 CFR 1.904(f)-12T(h) as it appeared in the Code of Federal Regulations as of April 1, 2010, in lieu of this paragraph (h) to taxable years beginning after December 31, 2006 and ending on or after December 21, 2007, but ending before April 7, 2011 provided that appropriate adjustments are made to eliminate duplicate benefits arising from application of 26 CFR 1.904(f)-12T(h) to taxable years that are not open for assessment. In addition, if a taxpayer that is a financial services entity (as defined in §1.904-4(e)(3)) chooses to apply 26 CFR 1.904(f)-12T(h) to taxable years ending before April 7, 2011, then as of the beginning of the taxpayer's first taxable year ending on or after April 7, 2011 any remaining balance in a passive category loss account that is attributable to a loss account in a pre-2007 separate category for high withholding tax interest shall be allocated to the general category or eliminated pursuant to §1.904(f)-12(h)(4), and any remaining balance in a separate limitation loss account with respect to passive category income that is attributable to a loss account with respect to a pre-2007 separate category for high withholding tax interest will be recaptured in such year and subsequent taxable years as general category income or eliminated pursuant to §1.904(f)-12(h)(4).

(i) [Reserved]

(j) Recapture in years beginning after December 31, 2017, of separate limitation losses, overall foreign losses, and overall domestic losses incurred in years beginning before January 1, 2018—(1) Definitions—(i) The term pre-2018 separate categories means the separate categories of income described in section 904(d) and any specified separate categories of income, as applicable to taxable years beginning before January 1, 2018.

(ii) The term post-2017 separate categories means the separate categories of income described in section 904(d) and any specified separate categories of income, as applicable to taxable years beginning after December 31, 2017.

(iii) The term specified separate category has the meaning set forth in §1.904-4(m)).

(2) Allocation of separate limitation loss or overall foreign loss account incurred in a pre-2018 separate category—(i) Allocation to the same category. To the extent that a taxpayer has a balance in any separate limitation loss or overall foreign loss account in a pre-2018 separate category at the end of the taxpayer's last taxable year beginning before January 1, 2018, the amount of such balance is allocated on the first day of the taxpayer's next taxable year to the same post-2017 separate category as the pre-2018 separate category of the separate limitation loss or overall foreign loss account.

(ii) Exception for general category separate limitation loss or overall foreign loss account—(A) In general. To the extent a taxpayer has a balance in any separate limitation loss or overall foreign loss account in the pre-2018 separate category for general category income at the end of the taxpayer's last taxable year beginning before January 1, 2018, a taxpayer may choose to allocate any such balance to the taxpayer's post-2017 separate category for foreign branch category income to the extent the balance in the loss account would have been allocated to the taxpayer's post-2017 separate category for foreign branch category income if that separate category applied in the year or years the losses giving rise to the account were incurred. Any remaining portion of the balance in the separate limitation loss or overall foreign loss account is allocated to the taxpayer's post-2017 separate category for general category income.

(B) Safe harbor. In lieu of applying paragraph (j)(2)(ii)(A) of this section, the taxpayer may choose to recapture the balance in any loss account described in paragraph (j)(2)(ii)(A) of this section from the first available income in the taxpayer's post-2017 separate category for general category income or foreign branch category income. If the sum of taxpayer's general category income and foreign branch category income for a taxable year subject to recharacterization exceeds the amount of the loss account described in paragraph (j)(2)(ii)(A) of this section that is to be recaptured, then the amount of general category income and foreign branch category income that will be recharacterized under the relevant recapture provisions is determined on a proportionate basis. The recapture under this paragraph (j)(2)(ii)(B) of any loss account described in paragraph (j)(2)(ii)(A) of this section is made before the recapture of any amount by which the balance of the loss account is increased after the end of the taxpayer's last taxable year beginning before January 1, 2018.

(C) Rules regarding the exception. A taxpayer applying the exception described in paragraph (j)(2)(ii)(A) or (B) of this section must apply the exception to all balances in any separate limitation loss or overall foreign loss account in a pre-2018 separate category for general category income at the end of the taxpayer's last taxable year beginning before January 1, 2018. A taxpayer may apply the exception on a timely filed original return (including extensions) or an amended return. A taxpayer that applies the exception on an amended return must make appropriate adjustments to eliminate any double benefit arising from application of the exception to years that are not open for assessment.

(3) Recapture of separate limitation loss or overall domestic loss that reduced pre-2018 separate category income—(i) Recapture as income in the same separate category. To the extent that at the end of the taxpayer's last taxable year beginning before January 1, 2018, a taxpayer has a balance in any separate limitation loss or overall domestic loss account which offset pre-2018 separate category income, such loss is recaptured in subsequent taxable years as income in the same post-2017 separate category as the pre-2018 separate category of income that was offset by the loss.

(ii) Exception for separate limitation loss or overall domestic loss that reduced general category income—(A) In general. To the extent that a taxpayer's separate limitation loss or overall domestic loss account offset pre-2018 separate category income that was general category income, a taxpayer may choose to recapture the balance in the loss account at the end of the taxpayer's last taxable year beginning before January 1, 2018, in subsequent taxable years as income in the post-2017 separate category for foreign branch category income to the extent the balance in the loss account would have offset foreign branch category income had that separate category applied in the year or years the losses were incurred. Any remaining portion of the balance in the loss account is recaptured as income in the taxpayer's post-2017 separate category for general category income.

(B) Safe harbor. In lieu of applying paragraph (j)(3)(ii)(A) of this section, a taxpayer that had unused foreign income taxes in a pre-2018 taxable year that were allocated to the foreign branch category under §1.904-2(j)(1)(iii)(A) or (B) may choose to recapture the balance in any loss account described in paragraph (j)(3)(ii)(A) of this section in subsequent taxable years ratably as income in the taxpayer's post-2017 separate categories for general category and foreign branch category income, based on the proportion in which any unused foreign taxes in the pre-2018 separate category for general category income are allocated under §1.904-2(j)(1)(iii)(A) or (B).

(C) Rules regarding the exception. A taxpayer applying the exception described in paragraph (j)(2)(ii)(A) or (B) of this section must apply the exception to the recapture of all balances at the end of the taxpayer's last taxable year beginning before January 1, 2018 in any separate limitation loss or overall domestic loss account which offset pre-2018 separate category income that was general category income. A taxpayer may apply the exception on a timely filed original return (including extensions) or an amended return. A taxpayer that applies the exception on an amended return must make appropriate adjustments to eliminate any double benefit arising from application of the exception to years that are not open for assessment.

(4) Treatment of foreign losses that are part of net operating losses incurred in pre-2018 taxable years which are carried forward to post-2017 taxable years—(i) Treatment as a loss in the same separate category. A foreign loss that is part of a net operating loss incurred in a taxable year beginning before January 1, 2018, which is carried forward, pursuant to section 172, to a taxable year beginning after December 31, 2017, will be carried forward under the rules of §1.904(g)-3(b)(2). For purposes of applying the rules of §1.904(g)-3(b)(2), the portion of a net operating loss carryforward that is attributable to a foreign loss from a pre-2018 separate category will be treated as a loss attributable to the same post-2017 separate category as the pre-2018 separate category.

(ii) Exception for general category foreign losses that are part of net operating losses—(A) In general. A taxpayer may choose to treat the portion of a net operating loss carryforward that is attributable to a foreign loss from the pre-2018 separate category for general category income as attributable to the post-2017 separate category for foreign branch category income to the extent the net operating loss would have been attributable to the taxpayer's post-2017 separate category for foreign branch category income had that separate category applied in the year or years the net operating loss arose. Any remaining portion of the net operating loss carryforward is treated as attributable to the taxpayer's post-2017 separate category for general category income.

(B) Safe harbor. In lieu of applying paragraph (j)(4)(ii)(A) of this section, for the post-2017 taxable year in which a net operating loss carryforward described in paragraph (j)(4)(ii)(A) of this section is used, the taxpayer may choose to treat the net operating loss carryforward as attributable to the taxpayer's post-2017 separate categories for general category income and foreign branch category income to the extent of any general category income and foreign branch category income, respectively, that is available in the carryforward year to be offset by the net operating loss carryforward. To the extent the net operating loss carryforward offsets any other income in the carryforward year, it is treated as attributable to the taxpayer's post-2017 separate category for general category income. If the sum of taxpayer's general category income and foreign branch income in the carryforward year exceeds the amount of the net operating loss carryforward, then the amount of each type of separate income that is offset by the net operating loss carryforward, and therefore the separate category treatment of the net operating loss carryforward, is be determined on a proportionate basis. A general category net operating loss to which the exception is applied is absorbed before any general category net operating loss that is incurred after the end of the taxpayer's last taxable year beginning before January 1, 2018.

(C) Rules regarding the exception. A taxpayer applying the exception described in paragraph (j)(4)(ii)(A) or (B) of this section must apply the exception to all of its net operating losses that are attributable to a foreign loss from the pre-2018 separate category for general category income. A taxpayer may apply the exception on a timely filed original return (including extensions) or an amended return. A taxpayer that applies the exception on an amended return must make appropriate adjustments to eliminate any double benefit arising from application of the exception to years that are not open for assessment.
