(a) Generally. The basis of partnership property is adjusted as a result of the transfer of an interest in a partnership by sale or exchange or on the death of a partner only if the election provided by section 754 (relating to optional adjustments to the basis of partnership property) is in effect with respect to the partnership. Whether or not the election provided in section 754 is in effect, the basis of partnership property is not adjusted as the result of a contribution of property, including money, to the partnership.

(b) Determination of adjustment. In the case of the transfer of an interest in a partnership, either by sale or exchange or as a result of the death of a partner, a partnership that has an election under section 754 in effect—

(1) Increases the adjusted basis of partnership property by the excess of the transferee's basis for the transferred partnership interest over the transferee's share of the adjusted basis to the partnership of the partnership's property; or

(2) Decreases the adjusted basis of partnership property by the excess of the transferee's share of the adjusted basis to the partnership of the partnership's property over the transferee's basis for the transferred partnership interest.

(c) Determination of transferee's basis in the transferred partnership interest. In the case of the transfer of a partnership interest by sale or exchange or as a result of the death of a partner, the transferee's basis in the transferred partnership interest is determined under section 742 and § 1.742-1. See also section 752 and §§ 1.752-1 through 1.752-5.

(d) Determination of transferee's share of the adjusted basis to the partnership of the partnership's property—(1) Generally. A transferee's share of the adjusted basis to the partnership of partnership property is equal to the sum of the transferee's interest as a partner in the partnership's previously taxed capital, plus the transferee's share of partnership liabilities. Generally, a transferee's interest as a partner in the partnership's previously taxed capital is equal to—

(i) The amount of cash that the transferee would receive on a liquidation of the partnership following the hypothetical transaction, as defined in paragraph (d)(2) of this section (to the extent attributable to the acquired partnership interest); increased by

(ii) The amount of tax loss (including any remedial allocations under § 1.704-3(d)), that would be allocated to the transferee from the hypothetical transaction (to the extent attributable to the acquired partnership interest); and decreased by

(iii) The amount of tax gain (including any remedial allocations under § 1.704-3(d)), that would be allocated to the transferee from the hypothetical transaction (to the extent attributable to the acquired partnership interest).

(2) Hypothetical transaction defined. For purposes of paragraph (d)(1) of this section, the hypothetical transaction means the disposition by the partnership of all of the partnership's assets, immediately after the transfer of the partnership interest, in a fully taxable transaction for cash equal to the fair market value of the assets. See § 1.460-4(k)(3)(v)(B) for a rule relating to the computation of income or loss that would be allocated to the transferee from a contract accounted for under a long-term contract method of accounting as a result of the hypothetical transaction.

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

(e) Allocation of basis adjustment. For the allocation of the basis adjustment under this section among the individual items of partnership property, see section 755 and the regulations thereunder.

(f) Subsequent transfers. Where there has been more than one transfer of a partnership interest, a transferee's basis adjustment is determined without regard to any prior transferee's basis adjustment. In the case of a gift of an interest in a partnership, the donor is treated as transferring, and the donee as receiving, that portion of the basis adjustment attributable to the gifted partnership interest. The provisions of this paragraph (f) are illustrated by the following example:

(g) Distributions—(1) Distribution of adjusted property to the transferee—(i) Coordination with section 732. If a partnership distributes property to a transferee and the transferee has a basis adjustment for the property, the basis adjustment is taken into account under section 732. See § 1.732-2(b).

(ii) Coordination with section 734. For certain adjustments to the common basis of remaining partnership property after the distribution of adjusted property to a transferee, see § 1.734-2(b).

(2) Distribution of adjusted property to another partner—(i) Coordination with section 732. If a partner receives a distribution of property with respect to which another partner has a basis adjustment, the distributee does not take the basis adjustment into account under section 732.

(ii) Reallocation of basis. A transferee with a basis adjustment in property that is distributed to another partner reallocates the basis adjustment among the remaining items of partnership property under § 1.755-1(c).

(3) Distributions in complete liquidation of a partner's interest. If a transferee receives a distribution of property (whether or not the transferee has a basis adjustment in such property) in liquidation of its interest in the partnership, the adjusted basis to the partnership of the distributed property immediately before the distribution includes the transferee's basis adjustment for the property in which the transferee relinquished an interest (either because it remained in the partnership or was distributed to another partner). Any basis adjustment for property in which the transferee is deemed to relinquish its interest is reallocated among the properties distributed to the transferee under § 1.755-1(c).

(4) Coordination with other provisions. The rules of sections 704(c)(1)(B), 731, 737, and 751 apply before the rules of this paragraph (g).

(5) Example. The provisions of this paragraph (g) are illustrated by the following example:

(h) Contributions of adjusted property—(1) Section 721(a) transactions. If, in a transaction described in section 721(a), a partnership (the upper tier) contributes to another partnership (the lower tier) property with respect to which a basis adjustment has been made, the basis adjustment is treated as contributed to the lower-tier partnership, regardless of whether the lower-tier partnership makes a section 754 election. The lower tier's basis in the contributed assets and the upper tier's basis in the partnership interest received in the transaction are determined with reference to the basis adjustment. However, that portion of the basis of the upper tier's interest in the lower tier attributable to the basis adjustment must be segregated and allocated solely to the transferee partner for whom the basis adjustment was made. Similarly, that portion of the lower tier's basis in its assets attributable to the basis adjustment must be segregated and allocated solely to the upper tier and the transferee. A partner with a basis adjustment in property held by a partnership that terminates under section 708(b)(1)(B) will continue to have the same basis adjustment with respect to property deemed contributed by the terminated partnership to the new partnership under § 1.708-1(b)(1)(iv), regardless of whether the new partnership makes a section 754 election.

(2) Section 351 transactions—(i) Basis in transferred property. A corporation's adjusted tax basis in property transferred to the corporation by a partnership in a transaction described in section 351 is determined with reference to any basis adjustments to the property under section 743(b) (other than any basis adjustment that reduces a partner's gain under paragraph (h)(2)(ii) of this section).

(ii) Partnership gain. The amount of gain, if any, recognized by the partnership on a transfer of property by the partnership to a corporation in a transfer described in section 351 is determined without reference to any basis adjustment to the transferred property under section 743(b). The amount of gain, if any, recognized by the partnership on the transfer that is allocated to a partner with a basis adjustment in the transferred property is adjusted to reflect the partner's basis adjustment in the transferred property.

(iii) Basis in stock. The partnership's adjusted tax basis in stock received from a corporation in a transfer described in section 351 is determined without reference to the basis adjustment in property transferred to the corporation in the section 351 exchange. A partner with a basis adjustment in property transferred to the corporation, however, has a basis adjustment in the stock received by the partnership in the section 351 exchange in an amount equal to the partner's basis adjustment in the transferred property, reduced by any basis adjustment that reduced the partner's gain under paragraph (h)(2)(ii) of this section.

(iv) Example. The following example illustrates the principles of this paragraph (h)(2):

(i) [Reserved]

(j) Effect of basis adjustment—(1) In general. The basis adjustment constitutes an adjustment to the basis of partnership property with respect to the transferee only. No adjustment is made to the common basis of partnership property. Thus, for purposes of calculating income, deduction, gain, and loss, the transferee will have a special basis for those partnership properties the bases of which are adjusted under section 743(b) and this section. The adjustment to the basis of partnership property under section 743(b) has no effect on the partnership's computation of any item under section 703.

(2) Computation of partner's distributive share of partnership items. The partnership first computes its items of income, deduction, gain, or loss at the partnership level under section 703. The partnership then allocates the partnership items among the partners, including the transferee, in accordance with section 704, and adjusts the partners' capital accounts accordingly. The partnership then adjusts the transferee's distributive share of the items of partnership income, deduction, gain, or loss, in accordance with paragraphs (j)(3) and (4) of this section, to reflect the effects of the transferee's basis adjustment under section 743(b). These adjustments to the transferee's distributive shares must be reflected on Schedules K and K-1 of the partnership's return (Form 1065). These adjustments to the transferee's distributive shares do not affect the transferee's capital account. See § 1.460-4(k)(3)(v)(B) for rules relating to the effect of a basis adjustment under section 743(b) that is allocated to a contract accounted for under a long-term contract method of accounting in determining the transferee's distributive share of income or loss from the contract.

(3) Effect of basis adjustment in determining items of income, gain, or loss—(i) In general. The amount of a transferee's income, gain, or loss from the sale or exchange of a partnership asset in which the transferee has a basis adjustment is equal to the transferee's share of the partnership's gain or loss from the sale of the asset (including any remedial allocations under § 1.704-3(d)), minus the amount of the transferee's positive basis adjustment for the partnership asset (determined by taking into account the recovery of the basis adjustment under paragraph (j)(4)(i)(B) of this section) or plus the amount of the transferee's negative basis adjustment for the partnership asset (determined by taking into the account the recovery of the basis adjustment under paragraph (j)(4)(ii)(B) of this section).

(ii) Examples. The following examples illustrate the principles of this paragraph (j)(3):

(4) Effect of basis adjustment in determining items of deduction—(i) Increases—(A) Additional deduction. The amount of any positive basis adjustment that is recovered by the transferee in any year is added to the transferee's distributive share of the partnership's depreciation or amortization deductions for the year. The basis adjustment is adjusted under section 1016(a)(2) to reflect the recovery of the basis adjustment.

(B) Recovery period—(1) In general. Except as provided in paragraph (j)(4)(i)(B)(2) of this section, for purposes of section 168, if the basis of a partnership's recovery property is increased as a result of the transfer of a partnership interest, then the increased portion of the basis is taken into account as if it were newly-purchased recovery property placed in service when the transfer occurs. Consequently, any applicable recovery period and method may be used to determine the recovery allowance with respect to the increased portion of the basis. However, no change is made for purposes of determining the recovery allowance under section 168 for the portion of the basis for which there is no increase. The partnership is allowed to deduct the additional first year depreciation under section 168(k) and § 1.168(k)-2 for an increase in the basis of qualified property, as defined in section 168(k) and § 1.168(k)-2, under section 743(b) in a class of property, as defined in § 1.168(k)-2(f)(1)(ii)(A) through (F), even if the partnership made the election under section 168(k)(7) and § 1.168(k)-2(f)(1) not to deduct the additional first year depreciation for all other qualified property of the partnership in the same class of property, as defined in § 1.168(k)-2(f)(1)(ii)(A) through (F), and placed in service in the same taxable year, provided the section 743(b) basis adjustment meets all requirements of section 168(k) and § 1.168(k)-2. Further, the partnership may make an election under section 168(k)(7) and § 1.168(k)-2(f)(1) not to deduct the additional first year depreciation for an increase in the basis of qualified property, as defined in section 168(k) and § 1.168(k)-2, under section 743(b) in a class of property, as defined in § 1.168(k)-2(f)(1)(ii)(A) through (F), and placed in service in the same taxable year, even if the partnership does not make that election for all other qualified property of the partnership in the same class of property, as defined in § 1.168(k)-2(f)(1)(ii)(A) through (F), and placed in service in the same taxable year. In this case, the section 743(b) basis adjustment must be recovered under a reasonable method.

(2) Remedial allocation method. If a partnership elects to use the remedial allocation method described in § 1.704-3(d) with respect to an item of the partnership's recovery property, then the portion of any increase in the basis of the item of the partnership's recovery property under section 743(b) that is attributable to section 704(c) built-in gain is recovered over the remaining recovery period for the partnership's excess book basis in the property as determined in the final sentence of § 1.704-3(d)(2). Any remaining portion of the basis increase is recovered under paragraph (j)(4)(i)(B)(1) of this section. The first sentence of this paragraph (j)(4)(i)(B)(2) does not apply to a partnership that is not a publicly traded partnership within the meaning of section 7704(b) with respect to any basis increase under section 743(b) that is recovered using the additional first year depreciation deduction under section 168(k).

(C) Examples. The provisions of this paragraph (j)(4)(i) are illustrated by the following examples:

(ii) Decreases—(A) Reduced deduction. The amount of any negative basis adjustment allocated to an item of depreciable or amortizable property that is recovered in any year first decreases the transferee's distributive share of the partnership's depreciation or amortization deductions from that item of property for the year. If the amount of the basis adjustment recovered in any year exceeds the transferee's distributive share of the partnership's depreciation or amortization deductions from the item of property, then the transferee's distributive share of the partnership's depreciation or amortization deductions from other items of partnership property is decreased. The transferee then recognizes ordinary income to the extent of the excess, if any, of the amount of the basis adjustment recovered in any year over the transferee's distributive share of the partnership's depreciation or amortization deductions from all items of property.

(B) Recovery period. For purposes of section 168, if the basis of an item of a partnership's recovery property is decreased as the result of the transfer of an interest in the partnership, then the decrease is recovered over the remaining useful life of the item of the partnership's recovery property. The portion of the decrease that is recovered in any year during the recovery period is equal to the product of—

(1) The amount of the decrease to the item's adjusted basis (determined as of the date of the transfer); multiplied by

(2) A fraction, the numerator of which is the portion of the adjusted basis of the item recovered by the partnership in that year, and the denominator of which is the adjusted basis of the item on the date of the transfer (determined prior to any basis adjustments).

(C) Examples. The provisions of this paragraph (j)(4)(ii) are illustrated by the following examples:

(5) Depletion. Where an adjustment is made under section 743(b) to the basis of partnership property subject to depletion, any depletion allowance is determined separately for each partner, including the transferee partner, based on the partner's interest in such property. See § 1.702-1(a)(8). For partnerships that hold oil and gas properties that are depleted at the partner level under section 613A(c)(7)(D), the transferee partner (and not the partnership) must make the basis adjustments, if any, required under section 743(b) with respect to such properties. See § 1.613A-3(e)(6)(iv).

(6) Example. The provisions of paragraph (j)(5) of this section are illustrated by the following example:

(k) Returns—(1) Statement of adjustments—(i) In general. A partnership that must adjust the bases of partnership properties under section 743(b) must attach a statement to the partnership return for the year of the transfer setting forth the name and taxpayer identification number of the transferee as well as the computation of the adjustment and the partnership properties to which the adjustment has been allocated.

(ii) Special rule. Where an interest is transferred in a partnership which holds oil and gas properties that are depleted at the partner level under section 613A(c)(7)(D), the transferee must attach a statement to the transferee's return for the year of the transfer, setting forth the computation of the basis adjustment under section 743(b) which is allocable to such properties and the specific properties to which the adjustment has been allocated.

(iii) Example. The provisions of paragraph (k)(1)(ii) of this section are illustrated by the following example:

(2) Requirement that transferee notify partnership—(i) Sale or exchange. A transferee that acquires, by sale or exchange, an interest in a partnership with an election under section 754 in effect for the taxable year of the transfer, must notify the partnership, in writing, within 30 days of the sale or exchange. The written notice to the partnership must be signed under penalties of perjury and must include the names and addresses of the transferee and (if ascertainable) of the transferor, the taxpayer identification numbers of the transferee and (if ascertainable) of the transferor, the relationship (if any) between the transferee and the transferor, the date of the transfer, the amount of any liabilities assumed or taken subject to by the transferee, and the amount of any money, the fair market value of any other property delivered or to be delivered for the transferred interest in the partnership, and any other information necessary for the partnership to compute the transferee's basis.

(ii) Special rule. A transferee that acquires, on the death of a partner, an interest in a partnership with an election under section 754 in effect for the taxable year of the transfer, must notify the partnership, in writing, within one year of the death of the deceased partner. The written notice to the partnership must be signed under penalties of perjury and must include the names and addresses of the deceased partner and the transferee, the taxpayer identification numbers of the deceased partner and the transferee, the relationship (if any) between the transferee and the transferor, the deceased partner's date of death, the date on which the transferee became the owner of the partnership interest, the fair market value of the partnership interest on the applicable date of valuation set forth in section 1014 or section 1022, the manner in which the fair market value of the partnership interest was determined, and the carryover basis as adjusted under section 1022 (if applicable).

(iii) Nominee reporting. If a partnership interest is transferred to a nominee which is required to furnish the statement under section 6031(c)(1) to the partnership, the nominee may satisfy the notice requirement contained in this paragraph (k)(2) by providing the statement required under § 1.6031(c)-1T, provided that the statement satisfies all requirements of § 1.6031(c)-1T and this paragraph (k)(2).

(3) Reliance. In making the adjustments under section 743(b) and any statement or return relating to such adjustments under this section, a partnership may rely on the written notice provided by a transferee pursuant to paragraph (k)(2) of this section to determine the transferee's basis in a partnership interest. The previous sentence shall not apply if any partner who has responsibility for federal income tax reporting by the partnership has knowledge of facts indicating that the statement is clearly erroneous.

(4) Partnership not required to make or report adjustments under section 743(b) until it has notice of the transfer. A partnership is not required to make the adjustments under section 743(b) (or any statement or return relating to those adjustments) with respect to any transfer until it has been notified of the transfer. For purposes of this section, a partnership is notified of a transfer when either—

(i) The partnership receives the written notice from the transferee required under paragraph (k)(2) of this section; or

(ii) Any partner who has responsibility for federal income tax reporting by the partnership has knowledge that there has been a transfer of a partnership interest.

(5) Effect on partnership of the failure of the transferee to comply. If the transferee fails to provide the partnership with the written notice required by paragraph (k)(2) of this section, the partnership must attach a statement to its return in the year that the partnership is otherwise notified of the transfer. This statement must set forth the name and taxpayer identification number (if ascertainable) of the transferee. In addition, the following statement must be prominently displayed in capital letters on the first page of the partnership's return for such year, and on the first page of any schedule or information statement relating to such transferee's share of income, credits, deductions, etc.: “RETURN FILED PURSUANT TO § 1.743-1(k)(5).” The partnership will then be entitled to report the transferee's share of partnership items without adjustment to reflect the transferee's basis adjustment in partnership property. If, following the filing of a return pursuant to this paragraph (k)(5), the transferee provides the applicable written notice to the partnership, the partnership must make such adjustments as are necessary to adjust the basis of partnership property (as of the date of the transfer) in any amended return otherwise to be filed by the partnership or in the next annual partnership return of income to be regularly filed by the partnership. At such time, the partnership must also provide the transferee with such information as is necessary for the transferee to amend its prior returns to properly reflect the adjustment under section 743(b).

(l) Effective/applicability date. The provisions in this section apply to transfers of partnership interests that occur on or after December 15, 1999. The provisions of this section relating to section 1022 are effective on and after January 19, 2017. The last three sentences of paragraph (j)(4)(i)(B)(1) of this section, and the last sentence of paragraph (j)(4)(i)(B)(2) of this section, apply to transfers of partnership interests that occur on or after September 24, 2019. However, a partnership may choose to apply the last three sentences in paragraph (j)(4)(i)(B)(1) of this section, and the last sentence of paragraph (j)(4)(i)(B)(2) of this section, for transfers of partnership interests that occur on or after September 28, 2017. A partnership may rely on the last three sentences in paragraph (j)(4)(i)(B)(1) of this section in regulation project REG-104397-18 (2018-41 I.R.B. 558) (see § 601.601(d)(2)(ii)(b) of this chapter) for transfers of partnership interests that occur on or after September 28, 2017, and ending before September 24, 2019.
