Exchanging property with a related party is legal, but Section 1031(f) attaches a two-year holding requirement and several traps that do not apply to exchanges between unrelated parties. Investors trading with a sibling, a parent, a controlled entity, or a business partner should understand these rules before assuming the transaction will work the same way an arm's-length exchange would.
Who Counts as a Related Party Under Section 1031(f)
Related parties are defined broadly under the tax code, generally including family members such as siblings, spouses, ancestors, and lineal descendants, along with entities in which the investor holds a significant ownership interest, typically more than 50 percent. A Washington investor exchanging property with a parent, an adult child, or an LLC they control alongside a family member falls under these rules, even if the transaction otherwise looks like an ordinary market-rate exchange with fair terms on both sides.
The Two-Year Holding Requirement
If a related-party exchange occurs, both parties generally have to hold onto their respective properties for at least two years after the exchange for the deferral to remain valid.
- If either party disposes of the property received in the exchange within two years, the original deferral can be retroactively disqualified for both sides
- The two-year clock runs from the date of the exchange, not from when either party later decides to sell
- Certain involuntary events, such as death, divorce, condemnation, or a disaster-related loss, can qualify for an exception to the two-year requirement
This holding requirement exists specifically to prevent related parties from using an exchange to quickly cash out a low-basis property through a family member without ever triggering tax, which is exactly the kind of transaction the rule is designed to catch.
The Basis-Shifting Trap the Rule Targets
Without the two-year rule, a related-party exchange could be used to move a high-basis property to a family member who intends to sell it quickly, while the original owner keeps a low-basis property with no near-term plan to sell, effectively shifting the tax exposure to whichever side is least likely to trigger it soon. Congress closed this loophole by tying deferral for both parties to a shared two-year holding commitment, so a quick post-exchange sale by either side unwinds the tax benefit for both, not just the party who sold.
Why an Intermediary in the Middle Does Not Automatically Fix the Problem
Some investors assume that routing a related-party transaction through a qualified intermediary, rather than exchanging directly with the relative, avoids the related-party rules entirely. The IRS has successfully challenged structures where an unrelated third party is used as an intermediate step specifically to disguise what is functionally a related-party exchange, particularly when the ultimate economic result mirrors a direct related-party swap. A Washington investor considering any exchange structure involving a family member or a controlled entity, even one that passes through additional parties, should get advice on whether the related-party rules still apply in substance before assuming an intermediary alone solves the problem.
Practical Guidance for Washington Investors Considering a Related-Party Exchange
Related-party exchanges are not prohibited, and there are legitimate reasons a family might restructure how they hold real estate this way, consolidating scattered Washington rental properties within a family group, for example, or separating jointly held property between siblings who want independent control. The key planning point is documenting both parties' intent to hold for the full two years from the outset, confirming that neither side has a near-term sale already planned or under discussion, and getting the exchange reviewed by someone familiar with Section 1031(f) before closing, since unwinding a disqualified exchange after both sides have already sold their new properties is far more difficult than structuring it correctly from the start.
Common Questions
Can I do a 1031 exchange with a family member?
Yes, but Section 1031(f) requires both parties to hold their respective properties for at least two years after the exchange, or the deferral can be disqualified retroactively for both sides.
What happens if I sell the property I received from a related-party exchange within two years?
The original deferral can be disqualified for both parties, not just the one who sold early, and the gain becomes taxable back to the year of the original exchange in most cases.
Are there exceptions to the two-year holding requirement?
Yes. Involuntary events such as the death of either party, divorce, condemnation, or a compulsory or involuntary conversion can qualify for an exception, though voluntary early sales generally do not.
Does using a qualified intermediary avoid the related-party rules?
Not automatically. The IRS looks at the substance of the transaction, and structures designed specifically to route around a related-party exchange through an intermediary have been challenged successfully in several cases.
Does an LLC I co-own with a relative count as a related party?
It can, if the combined ownership interest of the family group in that entity exceeds the ownership threshold used to define related parties under the tax code, generally more than 50 percent.
