§ 1.1033(a)-1. Involuntary conversions; nonrecognition of gain.

¶(a) In general. Section 1033 applies to cases where property is compulsorily or involuntarily converted. An involuntary conversion may be the result of the destruction of property in whole or in part, the theft of property, the seizure of property, the requisition or condemnation of property, or the threat or imminence of requisition or condemnation of property. An involuntary conversion may be a conversion into similar property or into money or into dissimilar property. Section 1033 provides that, under certain specified circumstances, any gain which is realized from an involuntary conversion shall not be recognized. In cases where property is converted into other property similar or related in service or use to the converted property, no gain shall be recognized regardless of when the disposition of the converted property occurred and regardless of whether or not the taxpayer elects to have the gain not recognized. In other types of involuntary conversion cases, however, the proceeds arising from the disposition of the converted property must (within the time limits specified) be reinvested in similar property in order to avoid recognition of any gain realized. Section 1033 applies only with respect to gains; losses from involuntary conversions are recognized or not recognized without regard to this section.
