26 U.S.C. § 1031 (INTERNAL REVENUE CODE)
§ 1031. Exchange of real property held for productive use or investment
(a) Nonrecognition of gain or loss from exchanges solely in kind
(1) In general
No gain or loss shall be recognized on the exchange of real property held for productive use in a trade or business or for investment if such real property is exchanged solely for real property of like kind which is to be held either for productive use in a trade or business or for investment.
(2) Exception for real property held for sale
This subsection shall not apply to any exchange of real property held primarily for sale.
(3) Requirement that property be identified and that exchange be completed not more than 180 days after transfer of exchanged property
For purposes of this subsection, any property received by the taxpayer shall be treated as property which is not like-kind property if—
(A) such property is not identified as property to be received in the exchange on or before the day which is 45 days after the date on which the taxpayer transfers the property relinquished in the exchange, or
(B) such property is received after the earlier of—
(i) the day which is 180 days after the date on which the taxpayer transfers the property relinquished in the exchange, or
(ii) the due date (determined with regard to extension) for the transferor’s return of the tax imposed by this chapter for the taxable year in which the transfer of the relinquished property occurs.
(b) Gain from exchanges not solely in kind
If an exchange would be within the provisions of subsection (a), of section 1035(a), of section 1036(a), or of section 1037(a), if it were not for the fact that the property received in exchange consists not only of property permitted by such provisions to be received without the recognition of gain, but also of other property or money, then the gain, if any, to the recipient shall be recognized, but in an amount not in excess of the sum of such money and the fair market value of such other property.
(c) Loss from exchanges not solely in kind
If an exchange would be within the provisions of subsection (a), of section 1035(a), of section 1036(a), or of section 1037(a), if it were not for the fact that the property received in exchange consists not only of property permitted by such provisions to be received without the recognition of gain or loss, but also of other property or money, then no loss from the exchange shall be recognized.
(d) Basis
If property was acquired on an exchange described in this section, section 1035(a), section 1036(a), or section 1037(a), then the basis shall be the same as that of the property exchanged, decreased in the amount of any money received by the taxpayer and increased in the amount of gain or decreased in the amount of loss to the taxpayer that was recognized on such exchange. If the property so acquired consisted in part of the type of property permitted by this section, section 1035(a), section 1036(a), or section 1037(a), to be received without the recognition of gain or loss, and in part of other property, the basis provided in this subsection shall be allocated between the properties (other than money) received, and for the purpose of the allocation there shall be assigned to such other property an amount equivalent to its fair market value at the date of the exchange. For purposes of this section, section 1035(a), and section 1036(a), where as part of the consideration to the taxpayer another party to the exchange assumed (as determined under section 357(d)) a liability of the taxpayer, such assumption shall be considered as money received by the taxpayer on the exchange.
(e) Application to certain partnerships
For purposes of this section, an interest in a partnership which has in effect a valid election under section 761(a) to be excluded from the application of all of subchapter K shall be treated as an interest in each of the assets of such partnership and not as an interest in a partnership.
(f) Special rules for exchanges between related persons
(1) In general
If—
(A) a taxpayer exchanges property with a related person,
(B) there is nonrecognition of gain or loss to the taxpayer under this section with respect to the exchange of such property (determined without regard to this subsection), and
(C) before the date 2 years after the date of the last transfer which was part of such exchange—
(i) the related person disposes of such property, or
(ii) the taxpayer disposes of the property received in the exchange from the related person which was of like kind to the property transferred by the taxpayer,
there shall be no nonrecognition of gain or loss under this section to the taxpayer with respect to such exchange; except that any gain or loss recognized by the taxpayer by reason of this subsection shall be taken into account as of the date on which the disposition referred to in subparagraph (C) occurs.
(2) Certain dispositions not taken into account
For purposes of paragraph (1)(C), there shall not be taken into account any disposition—
(A) after the earlier of the death of the taxpayer or the death of the related person,
(B) in a compulsory or involuntary conversion (within the meaning of section 1033) if the exchange occurred before the threat or imminence of such conversion, or
(C) with respect to which it is established to the satisfaction of the Secretary that neither the exchange nor such disposition had as one of its principal purposes the avoidance of Federal income tax.
(3) Related person
For purposes of this subsection, the term “related person” means any person bearing a relationship to the taxpayer described in section 267(b) or 707(b)(1).
(4) Treatment of certain transactions
This section shall not apply to any exchange which is part of a transaction (or series of transactions) structured to avoid the purposes of this subsection.
(g) Special rule where substantial diminution of risk
(1) In general
If paragraph (2) applies to any property for any period, the running of the period set forth in subsection (f)(1)(C) with respect to such property shall be suspended during such period.
(2) Property to which subsection applies
This paragraph shall apply to any property for any period during which the holder’s risk of loss with respect to the property is substantially diminished by—
(A) the holding of a put with respect to such property,
(B) the holding by another person of a right to acquire such property, or
(C) a short sale or any other transaction.
(h) Special rules for foreign real property
Real property located in the United States and real property located outside the United States are not property of a like kind.
