  1. (a)Introduction
    1. (1)Overview. As a general rule, the application of section 1031 requires a property-by-property comparison for computing the gain recognized and basis of property received in a like-kind exchange. This section provides an exception to this general rule in the case of an exchange of multiple properties. An exchange is an exchange of multiple properties if, under paragraph (b)(2) of this section, more than one exchange group is created. In addition, an exchange is an exchange of multiple properties if only one exchange group is created but there is more than one property being transferred or received within that exchange group. Paragraph (b) of this section provides rules for computing the amount of gain recognized in an exchange of multiple properties qualifying for nonrecognition of gain or loss under section 1031. Paragraph (c) of this section provides rules for computing the basis of properties received in an exchange of multiple properties qualifying for nonrecognition of gain or loss under section 1031.
    2. (2)General approach.
      1. (i)In general, the amount of gain recognized in an exchange of multiple properties is computed by first separating the properties transferred and the properties received by the taxpayer in the exchange into exchange groups in the manner described in paragraph (b)(2) of this section. The separation of the properties transferred and the properties received in the exchange into exchange groups involves matching up properties of a like kind of like class to the extent possible. Next, all liabilities assumed by the taxpayer as part of the transaction are offset by all liabilities of which the taxpayer is relieved as part of the transaction, with the excess liabilities assumed or relieved allocated in accordance with paragraph (b)(2)(ii) of this section. Then, the rules of section 1031 and the regulations thereunder are applied separately to each exchange group to determine the amount of gain recognized in the exchange. See §§ 1.1031(b)-1 and 1.1031(c)-1. Finally, the rules of section 1031 and the regulations thereunder are applied separately to each exchange group to determine the basis of the properties received in the exchange. See §§ 1.1031(d)-1 and 1.1031(d)-2.
      2. (ii)For purposes of this section, the exchanges are assumed to be made at arms' length, so that the aggregate fair market value of the property received in the exchange equals the aggregate fair market value of the property transferred. Thus, the amount realized with respect to the properties transferred in each exchange group is assumed to equal their aggregate fair market value.
  2. (b)Computation of gain recognized
    1. (1)In general. In computing the amount of gain recognized in an exchange of multiple properties, the fair market value must be determined for each property transferred and for each property received by the taxpayer in the exchange. In addition, the adjusted basis must be determined for each property transferred by the taxpayer in the exchange.
    2. (2)Exchange groups and residual group. The properties transferred and the properties received by the taxpayer in the exchange are separated into exchange groups and a residual group to the extent provided in this paragraph (b)(2).
      1. (i)Exchange groups. Each exchange group consists of the properties transferred and received in the exchange, all of which are of a like kind or like class. If a property could be included in more than one exchange group, the taxpayer may include the property in any of those exchange groups. Property eligible for inclusion within an exchange group does not include money or property described in section 1031(a)(2) (i.e., stock in trade or other property held primarily for sale, stocks, bonds, notes, other securities or evidences of indebtedness or interest, interests in a partnership, certificates of trust or beneficial interests, or choses in action). For example, an exchange group may consist of all exchanged properties that are within the same General Asset Class or within the same Product Class (as defined in § 1.1031(a)-2(b)). Each exchange group must consist of at least one property transferred and at least one property received in the exchange.
      2. (ii)Treatment of liabilities.
        1. (A)All liabilities assumed by the taxpayer as part of the exchange are offset against all liabilities of which the taxpayer is relieved as part of the exchange, regardless of whether the liabilities are recourse or nonrecourse and regardless of whether the liabilities are secured by or otherwise relate to specific property transferred or received as part of the exchange. See §§ 1.1031 (b)-1(c) and 1.1031(d)-2. For purposes of this section, liabilities assumed by the taxpayer as part of the exchange consist of liabilities of the other party to the exchange assumed by the taxpayer and liabilities subject to which the other party's property is transferred in the exchange. Similarly, liabilities of which the taxpayer is relieved as part of the exchange consist of liabilities of the taxpayer assumed by the other party to the exchange and liabilities subject to which the taxpayer's property is transferred.
        2. (B)If there are excess liabilities assumed by the taxpayer as part of the exchange (i.e., the amount of liabilities assumed by the taxpayer exceeds the amount of liabilities of which the taxpayer is relieved), the excess is allocated among the exchange groups (but not to the residual group) in proportion to the aggregate fair market value of the properties received by the taxpayer in the exchange groups. The amount of excess liabilities assumed by the taxpayer that are allocated to each exchange group may not exceed the aggregate fair market value of the properties received in the exchange group.
        3. (C)If there are excess liabilities of which the taxpayer is relieved as part of the exchange (i.e., the amount of liabilities of which the taxpayer is relieved exceeds the amount of liabilities assumed by the taxpayer), the excess is treated as a Class I asset for purposes of making allocations to the residual group under paragraph (b)(2)(iii) of this section.
        4. (D)Paragraphs (b)(2)(ii) (A), (B), and (C) of this section are applied in the same manner even if section 1031 and this section apply to only a portion of a larger transaction (such as a transaction described in section 1060(c) and § 1.1060-1T(b)). In that event, the amount of excess liabilities assumed by the taxpayer or the amount of excess liabilities of which the taxpayer is relieved is determined based on all liabilities assumed by the taxpayer and all liabilities of which the taxpayer is relieve as part of the larger transaction.
      3. (iii)Residual group. If the aggregate fair market value of the properties transferred in all of the exchange groups differs from the aggregate fair market value of the properties received in all of the exchange groups (taking liabilities into account in the manner described in paragraph (b)(2)(ii) of this section), a residual group is created. The residual group consists of an amount of money or other property having an aggregate fair market value equal to that difference. The residual group consists of either money or other property transferred in the exchange or money or other property received in the exchange, but not both. For this purpose, other property includes property described in section 1031(a)(2) (i.e., stock in trade or other property held primarily for sale, stocks, bonds, notes, other securities or evidences of indebtedness or interest, interests in a partnership, certificates of trust or beneficial interests, or choses in action), property transferred that is not of a like kind or like class with any property received, and property received that is not of a like kind or like class with any property transferred. The money and properties that are allocated to the residual group are considered to come from the following assets in the following order: first from Class I assets, then from Class II assets, then from Class III assets, and then from Class IV assets. The terms Class I assets, Class II assets, Class III assets, and Class IV assets have the same meanings as in § 1.338-6(b), to which reference is made by § 1.1060-1(c)(2). Within each Class, taxpayers may choose which properties are allocated to the residual group.
      4. (iv)Exchange group surplus and deficiency. For each of the exchange groups described in this section, an “exchange group surplus” or “exchange group deficiency,” if any, must be determined. An exchange group surplus is the excess of the aggregate fair market value of the properties received (less the amount of any excess liabilities assumed by the taxpayer that are allocated to that exchange group), in an exchange group over the aggregate fair market value of the properties transferred in that exchange group. An exchange group deficiency is the excess of the aggregate fair market value of the properties transferred in an exchange group over the aggregate fair market value of the properties received (less the amount of any excess liabilities assumed by the taxpayer that are allocated to that exchange group) in that exchange group.
    3. (3)Amount of gain recognized.
      1. (i)For purposes of this section, the amount of gain or loss realized with respect to each exchange group and the residual group is the difference between the aggregate fair market value of the properties transferred in that exchange group or residual group and the properties' aggregate adjusted basis. The gain realized with respect to each exchange group is recognized to the extent of the lesser of the gain realized and the amount of the exchange group deficiency, if any. Losses realized with respect to an exchange group are not recognized. See section 1031 (a) and (c). The total amount of gain recognized under section 1031 in the exchange is the sum of the amount of gain recognized with respect to each exchange group. With respect to the residual group, the gain or loss realized (as determined under this section) is recognized as provided in section 1001 or other applicable provision of the Code.
      2. (ii)The amount of gain or loss realized and recognized with respect to properties transferred by the taxpayer that are not within any exchange group or the residual group is determined under section 1001 and other applicable provisions of the Code, with proper adjustments made for all liabilities not allocated to the exchange groups or the residual group.
  3. (c)Computation of basis of properties received. In an exchange of multiple properties qualifying for nonrecognition of gain or loss under section 1031 and this section, the aggregate basis of properties received in each of the exchange groups is the aggregate adjusted basis of the properties transferred by the taxpayer within that exchange group, increased by the amount of gain recognized by the taxpayer with respect to that exchange group, increased by the amount of the exchange group surplus or decreased by the amount of the exchange group deficiency, and increased by the amount, if any, of excess liabilities assumed by the taxpayer that are allocated to that exchange group. The resulting aggregate basis of each exchange group is allocated proportionately to each property received in the exchange group in accordance with its fair market value. The basis of each property received within the residual group (other than money) is equal to its fair market value.
