Related Party 1031 Exchange Rules

Section 1031(f) applies special rules whenever an investor exchanges property with a related party, a category that includes family members and entities in which the investor holds more than fifty percent ownership. If either party disposes of the property received in the exchange within two years of the transfer, the original deferral is disqualified retroactively, and both parties must report the gain as if the exchange had never qualified for deferral.

The two year holding requirement exists to prevent related parties from using an exchange to shift basis or cash out low basis property while claiming deferral, a pattern sometimes described as basis shifting. Limited exceptions apply, including dispositions caused by death, involuntary conversion, or a demonstrated showing that neither the exchange nor the early disposition had tax avoidance as a principal purpose.

Exchanges that involve a qualified intermediary and an unrelated third party buyer, where the investor ultimately acquires replacement property from a related party, receive additional scrutiny under case law examining whether the related party also completed a qualifying exchange of its own. Orange County investors considering a related party transaction, such as exchanging with a family trust or a commonly owned entity, should confirm the structure and the two year holding period compliance with a CPA or attorney before closing, since related party exchanges carry meaningfully higher audit risk than exchanges with unrelated buyers and sellers.
