# 1.1374-4 Recognized built-in gain or loss.

(a) *Sales and exchanges*—(1) *In general.* Section 1374(d)(3) or 1374(d)(4) applies to any gain or loss recognized during the recognition period in a transaction treated as a sale or exchange for Federal income tax purposes.

(2) *Oil and gas property.* For purposes of paragraph (a)(1) of this section, an S corporation's adjusted basis in oil and gas property equals the sum of the shareholders' adjusted bases in the property as determined in section 613A(c)(11)(B).

(3) *Examples.* The rules of this paragraph (a) are illustrated by the following examples.

(b) *Accrual method rule*—(1) *Income items.* Except as otherwise provided in this section, any item of income properly taken into account during the recognition period is recognized built-in gain if the item would have been properly included in gross income before the beginning of the recognition period by an accrual method taxpayer (disregarding any method of accounting for which an election by the taxpayer must be made unless the taxpayer actually used the method when it was a C corporation).

(2) *Deduction items.* Except as otherwise provided in this section, any item of deduction properly taken into account during the recognition period is recognized built-in loss if the item would have been properly allowed as a deduction against gross income before the beginning of the recognition period to an accrual method taxpayer (disregarding any method of accounting for which an election by the taxpayer must be made unless the taxpayer actually used the method when it was a C corporation). In determining whether an item would have been properly allowed as a deduction against gross income by an accrual method taxpayer for purposes of this paragraph, section 461(h)(2)(C) and § 1.461-4(g) (relating to liabilities for tort, worker's compensation, breach of contract, violation of law, rebates, refunds, awards, prizes, jackpots, insurance contracts, warranty contracts, service contracts, taxes, and other liabilities) do not apply.

(3) *Examples.* The rules of this paragraph (b) are illustrated by the following examples.

(c) *Section 267(a)(2) and 404(a)(5) deductions*—(1) *Section 267(a)(2).* Notwithstanding paragraph (b)(2) of this section, any amount properly deducted in the recognition period under section 267(a)(2), relating to payments to related parties, is recognized built-in loss to the extent—

(i) All events have occurred that establish the fact of the liability to pay the amount, and the exact amount of the liability can be determined, as of the beginning of the recognition period; and

(ii) The amount is paid—

(A) In the first two and one-half months of the recognition period; or

(B) To a related party owning, under the attribution rules of section 267, less than 5 percent, by voting power and value, of the corporation's stock, both as of the beginning of the recognition period and when the amount is paid.

(2) *Section 404(a)(5).* Notwithstanding paragraph (b)(2) of this section, any amount properly deducted in the recognition period under section 404(a)(5), relating to payments for deferred compensation, is recognized built-in loss to the extent—

(i) All events have occurred that establish the fact of the liability to pay the amount, and the exact amount of the liability can be determined, as of the beginning of the recognition period; and

(ii) The amount is not paid to a related party to which section 267(a)(2) applies.

(3) *Examples.* The rules of this paragraph (c) are illustrated by the following examples.

(d) *Section 481(a) adjustments*—(1) *In general.* Any section 481(a) adjustment taken into account in the recognition period is recognized built-in gain or loss to the extent the adjustment relates to items attributable to periods before the beginning of the recognition period under the principles for determining recognized built-in gain or loss in this section. The principles for determining recognized built-in gain or loss in this section include, for example, the accrual method rule under paragraph (b) of this section.

(2) *Examples.* The rules of this paragraph (d) are illustrated by the following examples.

(e) *Section 995(b)(2) deemed distributions.* Any item of income properly taken into account during the recognition period under section 995(b)(2) is recognized built-in gain if the item results from a DISC termination or disqualification occurring before the beginning of the recognition period.

(f) *Discharge of indebtedness and bad debts.* Any item of income or deduction properly taken into account during the first year of the recognition period as discharge of indebtedness income under section 61(a)(12) or as a bad debt deduction under section 166 is recognized built-in gain or loss if the item arises from a debt owed by or to an S corporation at the beginning of the recognition period.

(g) *Completion of contract.* Any item of income properly taken into account during the recognition period under the completed contract method (as described in § 1.460-4(d)) where the corporation began performance of the contract before the beginning of the recognition period is recognized built-in gain if the item would have been included in gross income before the beginning of the recognition period under the percentage of completion method (as described in § 1.460-4(b)). Any similar item of deduction is recognized built-in loss if the item would have been allowed as a deduction against gross income before the beginning of the recognition period under the percentage of completion method.

(h) *Installment method*—(1) *In general.* If a corporation sells an asset before or during the recognition period and reports the income from the sale using the installment method under section 453 during or after the recognition period, that income is subject to tax under section 1374.

(2) *Limitation on amount subject to tax.* For purposes of paragraph (h)(1) of this section, the taxable income limitation under § 1.1374-2(a)(2) is equal to the amount by which the S corporation's net recognized built-in gain would have been increased from the year of the sale to the earlier of the year the income is reported under the installment method or the last year of the recognition period, assuming all income from the sale had been reported in the year of the sale and all provisions of section 1374 applied. For purposes of the preceding sentence, if the corporation sells the asset before the recognition period, the income from the sale that is not reported before the recognition period is treated as having been reported in the first year of the recognition period.

(3) *Rollover rule.* If the limitation in paragraph (h)(2) of this section applies, the excess of the amount reported under the installment method over the amount subject to tax under the limitation is treated as if it were reported in the succeeding taxable year(s), but only for succeeding taxable year(s) in the recognition period. The amount reported in the succeeding taxable year(s) under the preceding sentence is reduced to the extent that the amount not subject to tax under the limitation in paragraph (h)(2) of this section was not subject to tax because the S corporation had an excess of recognized built-in loss over recognized built-in gain in the taxable year of the sale and succeeding taxable year(s) in the recognition period.

(4) *Use of losses and section 1374 attributes.* If income is reported under the installment method by an S corporation for a taxable year after the recognition period and the income is subject to tax under paragraph (h)(1) of this section, the S corporation's section 1374 attributes may be used to the extent their use is allowed under all applicable provisions of the Code in determining the section 1374 tax. However, the S corporation's loss recognized for a taxable year after the recognition period that would have been recognized built-in loss if it had been recognized in the recognition period may not be used in determining the section 1374 tax.

(5) *Examples.* The rules of this paragraph (h) are illustrated by the following examples.

(i) *Partnership interests*—(1) *In general.* If an S corporation owns a partnership interest at the beginning of the recognition period or transfers property to a partnership in a transaction to which section 1374(d)(6) applies during the recognition period, the S corporation determines the effect on net recognized built-in gain from its distributive share of partnership items as follows—

(i) Step One: Apply the rules of section 1374(d) to the S corporation's distributive share of partnership items of income, gain, loss, or deduction included in income or allowed as a deduction under the rules of subchapter K to determine the extent to which it would have been treated as recognized built-in gain or loss if the partnership items had originated in and been taken into account directly by the S corporation (partnership 1374 items);

(ii) Step Two: Determine the S corporation's net recognized built-in gain without partnership 1374 items;

(iii) Step Three: Determine the S corporation's net recognized built-in gain with partnership 1374 items; and

(iv) Step Four: If the amount computed under Step Three (paragraph (i)(1)(iii) of this section) exceeds the amount computed under Step Two (paragraph (i)(1)(ii) of this section), the excess (as limited by paragraph (i)(2)(i) of this section) is the S corporation's partnership RBIG, and the S corporation's net recognized built-in gain is the sum of the amount computed under Step Two (paragraph (i)(1)(ii) of this section) plus the partnership RBIG. If the amount computed under Step Two (paragraph (i)(1)(ii) of this section) exceeds the amount computed under Step Three (paragraph (i)(1)(iii) of this section), the excess (as limited by paragraph (i)(2)(ii) of this section) is the S corporation's partnership RBIL, and the S corporation's net recognized built-in gain is the remainder of the amount computed under Step Two (paragraph (i)(1)(ii) of this section) after subtracting the partnership RBIL.

(2) *Limitations*—(i) *Partnership RBIG.* An S corporation's partnership RBIG for any taxable year may not exceed the excess (if any) of the S corporation's RBIG limitation over its partnership RBIG for prior taxable years. The preceding sentence does not apply if a corporation forms or avails of a partnership with a principal purpose of avoiding the tax imposed under section 1374.

(ii) *Partnership RBIL.* An S corporation's partnership RBIL for any taxable year may not exceed the excess (if any) of the S corporation's RBIL limitation over its partnership RBIL for prior taxable years.

(3) *Disposition of partnership interest.* If an S corporation disposes of its partnership interest, the amount that may be treated as recognized built-in gain may not exceed the excess (if any) of the S corporation's RBIG limitation over its partnership RBIG during the recognition period. Similarly, the amount that may be treated as recognized built-in loss may not exceed the excess (if any) of the S corporation's RBIL limitation over its partnership RBIL during the recognition period.

(4) *RBIG and RBIL limitations*—(i) *Sale of partnership interest.* An S corporation's RBIG or RBIL limitation is the total of the following—

(A) The amount that would be the amount realized if, at the beginning of the first day of the recognition period, the corporation had remained a C corporation and had sold its partnership interest (and any assets the corporation contributed to the partnership during the recognition period) at fair market value to an unrelated party; decreased by

(B) The corporation's adjusted basis in the partnership interest (and any assets the corporation contributed to the partnership during the recognition period) at the time of the sale referred to in paragraph (i)(4)(i)(A) of this section; and increased or decreased by

(C) The corporation's allocable share of the partnership's section 481(a) adjustments at the time of the sale referred to in paragraph (i)(4)(i)(A) of this section.

(ii) *Amounts of limitations.* If the result in paragraph (i)(4)(i) of this section is a positive amount, the S corporation has a RBIG limitation equal to that amount and a RBIL limitation of $0, but if the result in paragraph (i)(4)(i) of this section is a negative amount, the S corporation has a RBIL limitation equal to that amount and a RBIG limitation of $0.

(5) *Small interest exception*—(i) *In general.* Paragraph (i)(1) of this section does not apply to a taxable year in the recognition period if the S corporation's partnership interest represents less than 10 percent of the partnership's capital and profits at all times during the taxable year and prior taxable years in the recognition period, and the fair market value of the S corporation's partnership interest as of the beginning of the recognition period is less than $100,000.

(ii) *Contributed assets.* For purposes of paragraph (i)(5)(i) of this section, if the S corporation contributes any assets to the partnership during the recognition period and the S corporation held the assets as of the beginning of the recognition period, the fair market value of the S corporation's partnership interest as of the beginning of the recognition period is determined as if the assets were contributed to the partnership before the beginning of the recognition period (using the fair market value of each contributed asset as of the beginning of the recognition period). The contribution does not affect whether paragraph (i)(5)(i) of this section applies for taxable years in the recognition period before the taxable year in which the contribution was made.

(iii) *Anti-abuse rule.* Paragraph (i)(5)(i) of this section does not apply if a corporation forms or avails of a partnership with a principal purpose of avoiding the tax imposed under section 1374.

(6) *Section 704(c) gain or loss.* Solely for purposes of section 1374, an S corporation's section 704(c) gain or loss amount with respect to any asset is not reduced during the recognition period, except for amounts treated as recognized built-in gain or loss with respect to that asset under this paragraph.

(7) *Disposition of distributed partnership asset.* If on the first day of the recognition period an S corporation holds an interest in a partnership that holds an asset and during the recognition period the partnership distributes the asset to the S corporation that thereafter disposes of the asset, the asset is treated as having been held by the S corporation on the first day of the recognition period and as having the fair market value and adjusted basis in the hands of the S corporation that it had in the hands of the partnership on that day.

(8) *Examples.* The rules of this paragraph (i) are illustrated by the following examples.

(a) In 1996, P's partnership 1374 items are—

(1) Ordinary income of $25,000; and

(2) Capital gain of $75,000.

(b) X itself has—

(1) Recognized built-in ordinary income of $40,000; and

(2) Recognized built-in capital loss of $90,000.

(ii) X's net recognized built-in gain for 1996 computed without partnership 1374 items is $40,000 and with partnership 1374 items is $65,000 ($40,000 + $25,000 = $65,000). Thus, X's partnership RBIG is $25,000 for the year except as limited under paragraph (i)(2)(i) of this section. Because X's RBIG limitation is $0, X's partnership RBIG of $25,000 is limited to $0 and X's net recognized built-in gain for the year is $40,000.

(a) In 1996, P's partnership 1374 items are—

(1) Ordinary income of $25,000; and

(2) Capital loss of $90,000.

(b) Y itself has—

(1) recognized built-in ordinary income of $40,000; and

(2) recognized built-in capital gain of $75,000.

(ii) Y's net recognized built-in gain for 1996 computed without partnership 1374 items is $115,000 ($40,000 + $75,000 = $115,000) and with partnership 1374 items is $65,000 ($40,000 + $25,000 = $65,000). Thus, Y's partnership RBIL is $50,000 for the year except as limited under paragraph (i)(2)(ii) of this section. Because Y's RBIL limitation is $0, Y's partnership RBIL of $50,000 is limited to $0 and Y's net recognized built-in gain is $115,000.
