(2) Conversion into money Into money or into property not similar or related in service or use to the converted property, the gain (if any) shall be recognized except to the extent hereinafter provided in this paragraph: (A) Nonrecognition of gain If the taxpayer during the period specified in subparagraph (B), for the purpose of replacing the property so converted, purchases other property similar or related in service or use to the property so converted, or purchases stock in the acquisition of control of a corporation owning such other property, at the election of the taxpayer the gain shall be recognized only to the extent that the amount realized upon such conversion (regardless of whether such amount is received in one or more taxable years) exceeds the cost of such other property or such stock. Such election shall be made at such time and in such manner as the Secretary may by regulations prescribe. For purposes of this paragraph— (i) no property or stock acquired before the disposition of the converted property shall be considered to have been acquired for the purpose of replacing such converted property unless held by the taxpayer on the date of such disposition; and (ii) the taxpayer shall be considered to have purchased property or stock only if, but for the provisions of subsection (b) of this section, the unadjusted basis of such property or stock would be its cost within the meaning of section 1012. (B) Period within which property must be replaced The period referred to in subparagraph (A) shall be the period beginning with the date of the disposition of the converted property, or the earliest date of the threat or imminence of requisition or condemnation of the converted property, whichever is the earlier, and ending— (i) 2 years after the close of the first taxable year in which any part of the gain upon the conversion is realized, or (ii) subject to such terms and conditions as may be specified by the Secretary, at the close of such later date as the Secretary may designate on application by the taxpayer. Such application shall be made at such time and in such manner as the Secretary may by regulations prescribe. (C) Time for assessment of deficiency attributable to gain upon conversion If a taxpayer has made the election provided in subparagraph (A), then— (i) the statutory period for the assessment of any deficiency, for any taxable year in which any part of the gain on such conversion is realized, attributable to such gain shall not expire prior to the expiration of 3 years from the date the Secretary is notified by the taxpayer (in such manner as the Secretary may by regulations prescribe) of the replacement of the converted property or of an intention not to replace, and (ii) such deficiency may be assessed before the expiration of such 3–year period notwithstanding the provisions of section 6212(c) or the provisions of any other law or rule of law which would otherwise prevent such assessment. (D) Time for assessment of other deficiencies attributable to election If the election provided in subparagraph (A) is made by the taxpayer and such other property or such stock was purchased before the beginning of the last taxable year in which any part of the gain upon such conversion is realized, any deficiency, to the extent resulting from such election, for any taxable year ending before such last taxable year may be assessed (notwithstanding the provisions of section 6212(c) or 6501 or the provisions of any other law or rule of law which would otherwise prevent such assessment) at any time before the expiration of the period within which a deficiency for such last taxable year may be assessed.
