TD 10048, May 20, 2026

Under section 741 of the Internal Revenue Code (Code), "gain or loss recognized by a transferor partner upon sale or exchange of a partnership interest is considered as gain or loss from the sale or exchange of a capital asset, except as provided in section 751". Section 751(a) mandates that amounts received by a transferor partner attributable to unrealized receivables or inventory items of the partnership "will be considered as an amount realized from the sale or exchange of property other than a capital asset". The regulations designate these specific transactions as a "section 751(a) exchange" under § 1.6050K-1(a)(4)(i).

To ensure proper reporting of these transactions, "Section 6050K(a) requires a partnership to file a return if there is a section 751(a) exchange of any interest in the partnership during any calendar year". Under the prior regulatory framework, § 1.6050K-1(c)(1) required partnerships to furnish a statement to both the transferor and transferee by January 31 of the year following the exchange, or 30 days after the partnership receives notice of the exchange, whichever is later. Furthermore, prior to its removal by these final regulations, § 1.6050K-1(c)(2) "required a partnership to furnish to a transferor partner the information necessary for the transferor to make the transferor partner’s required statement in §1.751-1(a)(3)". Section 1.751-1(a)(3) compels the transferor to separately state the date of the exchange, the amount of gain or loss attributable to section 751 property, and the amount attributable to capital gain or loss. This granular data reporting aligned directly with Part IV of Form 8308, Report of a Sale or Exchange of Certain Partnership Interests.

IRS Justification for Modifying the Regulations

The stringent timing of the prior regulations created significant compliance hurdles for practitioners and partnerships. The final regulations address this specific burden. The Department of the Treasury and the Internal Revenue Service (IRS) justified the modification based on stakeholder feedback, noting "that many partnerships are unable to furnish the information required in Part IV of the Form 8308 to transferors and transferees by the January 31 due date prescribed by §1.6050K-1(c)(1) because, in many cases, partnerships do not have all the information required by Part IV of the Form 8308 by January 31 of the year following the calendar year in which the section 751(a) exchange occurred".

Provisions Modified from Prior Regulations

To alleviate this timing mismatch, the final regulations (TD 10048) formally amend 26 CFR part 1 under section 6050K of the Code. The specific modifications include:

Removal of § 1.6050K-1(c)(2): The final regulations completely remove this paragraph, eliminating the direct regulatory requirement to furnish the complex section 751 computational information to the transferor by the strict January 31 deadline.
Amendment of § 1.6050K-1(c)(1): Prior to this modification, the regulation "generally required a partnership to use a copy of the completed Form 8308 as the required statement". The final regulations revise the introductory text to state that the partnership must now furnish "a copy of the Form 8308, filled out in accordance with the instructions accompanying the form, as a statement unless the Form 8308 contains information with respect to more than one section 751(a) exchange".
Amendment of § 1.6050K-1(c)(1)(i): The language was slightly revised to clarify that substitute statements furnished in lieu of Form 8308 must indicate that "The information shown on the statement will be supplied to the Internal Revenue Service".

Final Regulations Compared to Proposed Regulations

Tax professionals reviewing these final rules will find no deviations from the proposed regulations (REG-108822-25) published on August 19, 2025. According to the preamble of the final regulations, "The Treasury Department and IRS did not receive any comments pertaining to the proposed regulations, and no public hearing was requested or held. Accordingly, these final regulations adopt the proposed regulations without change".

Ongoing Reporting Obligations for Partnerships

While the removal of § 1.6050K-1(c)(2) relaxes the January 31 reporting deadline for Part IV of Form 8308, tax professionals must be aware that the substantive reporting requirements have merely been shifted rather than eliminated.

First, partnerships are still required to furnish "only Parts I, II, and III of Form 8308, or a statement that includes the same information, to the transferor and transferee in a section 751(a) exchange by the later of (1) January 31 of the year following the calendar year in which the section 751(a) exchange occurred, or (2) 30 days after the partnership has received notice of the exchange".

Second, the final regulations do not alter the partnership's ultimate filing obligation to the IRS. Pursuant to § 1.6031(a)-1(a)(2), a "partnership would be required to file the completed Form 8308, including Part IV, as an attachment to its Form 1065, for the taxable year of the partnership that includes the last day of the calendar year in which the section 751(a) exchange took place".

Finally, the burden of communicating the section 751(a) gain or loss to the transferor partner remains firmly in place through the Schedule K-1 process. Pursuant to § 1.6031(b)-1T(a)(3), "the partnership will also continue to be required to report the information required of the transferor in §1.751-1(a)(3) to the transferor (including the information required in Part IV of the Form 8308), in the Schedule K-1 (Form 1065), Partner’s Share of Income, Deductions, Credits, etc., issued to the transferor partner as provided by the Form and Instructions to the Schedule K-1 (Form 1065)".

Effective and Applicability Dates

The final regulations are effective on May 20, 2026, the date of publication in the Federal Register. The amendments to § 1.6050K-1(c)(1) and (c)(1)(i) explicitly "apply to returns filed for taxable years ending on or after" the date of publication in the Federal Register. However, as previously noted in the proposed regulations, partnerships were permitted to rely on the proposed rules "with respect to section 751(a) exchanges occurring on or after January 1, 2025, and before the date the regulations are published as final regulations in the Federal Register".
