A related-party exchange under Section 1031(f) is permitted — a sibling, a parent, a child, or an entity the investor controls can all be on the other side of the deal — but permission comes with a string attached: both sides have to sit on the property they received for two years before the deal is considered settled. The string exists because, without it, a related-party exchange would be an easy way to shift basis or cash out of an asset while skipping the real, arm's-length holding period an exchange is supposed to require. As with every 1031 mechanism, the tax is deferred rather than erased, and breaking the two-year hold simply puts the deferred gain back on the table.
Who Counts as a Related Party
Rather than spelling out its own list, Section 1031(f) leans on attribution rules borrowed from elsewhere in the code, which cover close family in both directions — a brother or sister, a husband or wife, a parent or grandparent going up the family tree, a child or grandchild going down it — plus any entity where the investor's ownership stake clears roughly 50 percent. A Kansas City investor exchanging with a business partner who is not a family member and holds no ownership overlap in the investor's entities typically falls outside this definition, while an exchange between an investor and their own wholly owned LLC falls squarely inside it.
The Two-Year Holding Requirement
Picture the two-year hold as a shared probation period: the property the investor ended up with and the property the related party ended up with both need to go untouched for two years from the exchange date, and an early sale on either side converts what was deferred gain into recognized gain, dated to the year of the original exchange rather than the year of the sale. That retroactive reach is what raises the stakes above a typical exchange requirement, since the investor's own tax position can be undone by a decision the related party makes that the investor may not fully control.
Why Related-Party Exchanges Draw Extra Scrutiny
The IRS has specifically pursued related-party exchanges structured to cash out appreciated property through a related party who then sells it shortly after, effectively using the relative's shorter holding intentions to convert what looks like a deferred exchange into a disguised sale. A Kansas City investor considering a related-party exchange, such as trading an investment property with a parent or an entity controlled by a sibling, should document the business purpose for the transaction and confirm both sides genuinely intend to hold for the full two years rather than treating the requirement as a formality.
What a Retroactive Disqualification Costs in Missouri
If a related-party exchange unwinds because the two-year hold was broken, the recognized gain flows through to the investor's federal return for the year of the original exchange and, for a Missouri-based investor, through Missouri's graduated state income tax as well, layered on top of whatever federal tax is due. Because the disqualification is retroactive, the investor may also owe interest on the underpayment for the intervening tax years, which is a cost that is easy to overlook when the early disposition happens well after the original exchange closed.
A Kansas City investor structuring a related-party exchange across the state line, where the investor sits in Missouri and the related party's property sits in Kansas or the reverse, should have both the federal exposure and the applicable state exposure modeled out in advance, since the two-year hold is a shared risk even though only one side may ultimately decide to sell early.
Exceptions to the Two-Year Rule
A handful of circumstances let the two-year hold give way: one party's death, a forced disposition from a casualty loss, or a demonstration to the IRS that tax avoidance was not behind either the exchange or the early sale. The last of those routes is narrow and hard to walk without solid documentation, which is why most advisors plan around the two-year requirement as fixed rather than banking on an exception coming through. Kept from the start rather than pieced together after an early sale is already under discussion, a written record of the business reasons for the exchange is the strongest evidence available if that exception is ever tested.
Common Questions
Can an investor do a 1031 exchange with a family member?
Yes, but Section 1031(f) requires both the investor and the related party to hold their respective properties for at least two years after the exchange, or the deferred gain is retroactively recognized.
What happens if the related party sells their property early?
If either side disposes of their property before the two-year holding period ends, the original exchange is disqualified retroactively, and the gain becomes taxable as of the year of the exchange.
Does exchanging with a wholly owned LLC count as a related-party transaction?
Yes, an entity in which the investor holds more than a 50 percent ownership stake is generally treated as a related party under Section 1031(f).
Are there any exceptions to the two-year holding requirement?
Yes, exceptions exist for a disposition caused by death or an involuntary conversion, and a narrow exception applies if tax avoidance can be shown not to have been a principal purpose of the transaction.
Why does the IRS scrutinize related-party exchanges more closely?
Because a related party could sell shortly after the exchange to effectively cash out appreciated property while the original investor claims deferral, the two-year hold and added scrutiny exist to prevent that kind of disguised sale.
