Chapter 28: Nontaxable Exchanges and Involuntary Conversions

REG property-transaction coverage for Section 1031 exchanges, Section 1033 conversions, deferred gain, and replacement basis.

This chapter covers property transactions where gain may be deferred instead of recognized immediately. These rules are highly testable because the outcome depends on satisfying specific structural requirements and then carrying the deferred consequence into replacement-property basis.

  • Read this chapter when you understand realized gain but not when it becomes recognized.
