SUPPLEMENTARY INFORMATION:

Background

This document contains amendments to 26 CFR Part 1 under section 1031(a) relating to the exchange of items of personal property that are within the same product class. Section 1031(a)(1) generally provides that no gain or loss shall be recognized on the exchange of property held for productive use in a trade or business or for investment if the property is exchanged solely for property of like kind to be held either for productive use in a trade or business or for investment. Thus, for a transaction to qualify as an exchange under section 1031, the transaction must constitute an exchange, the property relinquished and the property received in the exchange must be held for use in a trade or business or for investment, and the exchanged properties must be of like kind.

Section 1.1031(a)–2(a) provides that personal properties of a like class are to be considered of like kind for purposes of section 1031. Under §1.1031(a)–2(b), depreciable tangible personal property is of a like class to other depreciable tangible personal property if the exchanged properties are either within the same general asset class or within the same product class . The general asset classes are derived from Rev. Proc. 87–56, 1987–2 C.B. 674, (dealing with depreciation of personal property). Section 1.1031(a)–2(b)(2) adopts certain of those general asset classes to determine what property is of like kind for purposes of exchanging depreciable tangible personal property under section 1031, and identifies the types of personal property included in each general asset class listed.

Section 1.1031(a)–2(b)(3) provides, in part, that property within a product class consists of depreciable tangible personal property that is listed in a 4-digit product class (or “code”) within Division D (pertaining to the manufacturing sector of the economy) of Executive Office of the President, Office of Management and Budget, Standard Industrial Clas- sification Manual (1987) (SIC Manual). Section 1.1031(a)–2(b)(4) states that the SIC Manual generally is modified every

5 years and that the product classes for section 1031 purposes will follow the modifications of product classes in the SIC Manual.

Effective January 1, 1997, the Department of Commerce discontinued the SIC system set forth in the SIC Manual and adopted NAICS as set forth in Executive Office of the President, Office of Management and Budget, North American Indus- try Classification System, United States, 1997 (NAICS Manual). The NAICS Manual was updated in 2002. Copies of the NAICS Manual may be obtained from the National Technical Information Service of the Department of Commerce and may be accessed, with a more complete listing of manufactured products and manufacturing industries, on the internet at http://www.census.gov/naics .

Explanation of Provisions

As a result of the replacement of the SIC system with NAICS, these temporary regulations discontinue the use of SIC codes and adopt Sectors 31 through 33 of NAICS (pertaining to manufacturing) as the system for defining the product classes for purposes of like-kind exchanges of depreciable tangible personal property. Within NAICS, product classes are designated using 6-digit codes rather than the 4-digit codes assigned to product classes under the SIC system. However, properties within the same product class under the 4-digit SIC system generally will be of the same product class under the 6-digit NAICS. For example, under the SIC codes, dairy equipment and haying machinery are within the same product class (SIC code 3523). Under NAICS, milking machines and haying machines are also within the same product class (NAICS code 333111).

The temporary regulations generally incorporate the provisions of §1.1031(a)–2(b)(3) relating to the use of product classes but substitute NAICS codes for SIC codes. For example, §1.1031(a)–2(b)(3) provides that, under the 4-digit SIC system, any 4-digit product class ending in 9 (a miscellaneous category) is not property within a product class. Similarly, the temporary regulations

2004–38 I.R.B. 489 September 20, 2004

§1.1031(a)–2 Additional rules for exchanges of personal property.

        • (b)(3) through (b)(6) [Reserved]. For further guidance, see §1.1031(a)–2T(b)(3) through (b)(6).

(b)(7) * - Example 3 . [Reserved]. For further guidance, see §1.1031(a)–2T(b)(2), Exam- ple 3 .

Example 4 . [Reserved]. For further guidance, see §1.1031(a)–2T(b)(2), Exam- ple 4 .

        • (d) * * * For transfers of property made by taxpayers on or after January 1, 1997, see §1.1031(a)–2T(d).

Par. 3. Section 1.1031(a)–2T is added to read as follows:

§1.1031(a)–2T Additional rules for exchanges of personal property (temporary).

(a) through (b)(2) [Reserved]. For further guidance, see §1.1031(a)–2(a) through (b)(2).

(3) Product classes . Except as provided in paragraphs (b)(4) and (b)(5) of this section, or as provided by the Commissioner in published guidance of general applicability, property within a product class consists of depreciable tangible personal property that is described in a 6-digit product class within Sectors 31, 32, and 33 (pertaining to manufacturing industries) of the North American Industry Classification System (NAICS), set forth in Executive Office of the President, Office of Management and Budget, North Ameri- can Industry Classification System, United States, 2002 (NAICS Manual), as periodically updated. Copies of the NAICS Manual may be obtained from the National Technical Information Service, an agency of the U.S. Department of Commerce, and may be accessed on the internet. Sectors 31 through 33 of the NAICS Manual contain listings of specialized industries for the manufacture of described products and equipment. For this purpose, any 6-digit NAICS product class with a last digit of 9 (a miscellaneous category) is not a product class for purposes of this section. If a property is listed in more than one product class, the property is treated as listed in any one of those product classes. A prop

provide that any NAICS 6-digit product class ending in 9 is not property within a product class. Accordingly, such property, and property that is not listed in a 6-digit product class, cannot be of a like class to other property based on the 6-digit NAICS Manual classification. Taxpayers, however, may still demonstrate that these properties are of a like kind.

Comments are specifically requested regarding the continued utility of SIC codes and any potential problems in adopting the 6-digit NAICS codes in lieu of the 4-digit SIC codes, including specific examples of how a product class is narrowed if the 6-digit NAICS code is used and whether this would be a disadvantage to any class of taxpayers.

The temporary regulations incorporate the provisions of §1.1031(a)–2(b)(4) that permit taxpayers, in structuring like-kind exchanges, to rely on modifications to the product classes resulting from revisions to the NAICS Manual. The temporary regulations omit the provisions of §1.1031(a)–2(b)(4) that permit taxpayers to rely on modifications to the general asset classes in Rev. Proc. 87–56 for purposes of structuring like-kind exchanges. Under section 6253 of the Technical and Miscellaneous Revenue Act of 1988 (Public Law 100–647, 102 Stat. 3342), the Commissioner may not modify the asset classes in Rev. Proc. 87–56 for depreciation purposes. However, the temporary regulations provide that the Commissioner may, through published guidance of general applicability, supplement, modify, clarify and update the rules for the classification of properties. Therefore, the Commissioner may determine through published guidance not to follow a general asset class or product class for purposes of identifying property of like class or may determine that other properties not listed within the same or in any product class or general asset class nevertheless are of a like class.

Effective Date

In general, the temporary regulations apply to transfers of property made by taxpayers on or after August 12, 2004. However, taxpayers may apply the temporary regulations to transfers of property made by taxpayers on or after January 1, 1997, in taxable years for which the period of limi

tation has not expired. The temporary regulations include a transition rule permitting taxpayers to treat properties within the same product classes under a 4-digit SIC code as properties of like class for transfers of property made by taxpayers on or before the date these temporary regulations are published as final regulations in the Fed- eral Register . Comments are specifically requested on whether a longer transition period should be provided before the use of the SIC codes is discontinued.

Special Analyses

It has been determined that this Treasury decision is not a significant regulatory action as defined in Executive Order 12866. Therefore, a regulatory assessment is not required. It also has been determined that section 553(b) of the Administrative Procedure Act (5 U.S.C. chapter 5) does not apply to these regulations. Please refer to the cross-referenced notice of proposed rulemaking published elsewhere in this issue of the Bulletin for applicability of the Regulatory Flexibility Act (5 U.S.C. Chapter 6). Pursuant to section 7805(f) of the Code, these temporary regulations will be submitted to the Chief Counsel for Advocacy of the Small Business Administration for comment on their impact on small business.

Drafting Information

The principal author of these temporary regulations is J. Peter Baumgarten of the Office of the Associate Chief Counsel (Income Tax and Accounting). However, other personnel from the IRS and Treasury participated in their development.
