Exchanging property with a related party is allowed under Section 1031, but it comes with a specific two-year hold requirement under Section 1031(f) that does not apply to exchanges between unrelated parties. A Milwaukee investor exchanging a property with a sibling, parent, or an entity they control needs to understand this rule before closing, because a related-party exchange that looks complete on paper can still unwind and become fully taxable if either party disposes of their property within the following two years.
Who Counts as a Related Party
The related-party definition under Section 1031(f) borrows from broader tax code definitions and covers more relationships than most investors expect. Immediate family members, including siblings, spouses, ancestors, and descendants, are related parties. So are entities in which the investor holds more than a 50 percent ownership interest, such as a closely held LLC or corporation. Business partners and more distant relatives, like cousins or in-laws, are generally not covered by the related-party rule, but the exact boundary depends on the specific relationship and ownership structure involved.
The Two-Year Hold Requirement
When a 1031 exchange occurs between related parties, both parties generally must hold their respective properties for at least two years after the exchange for the deferral to remain valid. If either party sells, transfers, or otherwise disposes of their property within that two-year window, the original exchange is retroactively disqualified and both parties can owe tax as if the original transaction had never qualified for deferral in the first place.
Why This Rule Exists
The two-year hold requirement targets a specific pattern the IRS considers abusive: swapping a low-basis property for a related party's high-basis property specifically to shift the built-in gain onto whichever party is about to sell to an outside buyer anyway. Without the hold requirement, a family could effectively cash out appreciated real estate through a related party's exchange and avoid recognizing the gain, which is exactly what Section 1031(f) was written to prevent.
Common Traps in Related-Party Exchanges
Several situations create related-party exposure that investors do not always recognize at the time of the transaction.
- exchanging property with an LLC the investor controls, even indirectly through another entity
- a parent and adult child exchanging Milwaukee-area rental properties to consolidate holdings
- using a related party as an intermediate step in a larger multi-property transaction
- disposing of the received property within two years for reasons unrelated to the original exchange, such as an unexpected sale offer
None of these situations are prohibited outright, but each one requires tracking the two-year clock carefully, since an unrelated later event, like an unplanned sale, can still trigger the disqualification.
Exceptions to the Two-Year Rule
A small number of exceptions exist, including dispositions caused by death, involuntary conversion, or circumstances the IRS determines were not primarily tax-motivated. These exceptions are narrow and fact-specific, and an investor should not assume a particular situation qualifies without documenting the reasoning at the time, rather than after the fact when a return is being prepared and the disposition has already happened. A Milwaukee family consolidating rental holdings between a parent and an adult child should keep contemporaneous notes on why the exchange was structured the way it was, since that record is what supports an exception claim years later if the two-year clock is ever questioned.
Common 1031 Exchange Questions
What is the minimum hold period after a related-party 1031 exchange?
Two years from the date of the exchange, for both parties involved, under Section 1031(f). Disposing of the property sooner generally disqualifies the original exchange.
Does exchanging property with an LLC the investor controls count as a related-party exchange?
Yes, if the investor holds more than a 50 percent ownership interest in the entity. Majority-owned entities are treated as related parties under the rule.
What happens if the two-year hold is violated?
The original exchange is retroactively disqualified, and both parties can owe tax on the gain as if the transaction had never qualified for 1031 deferral.
Are there any exceptions to the two-year hold requirement?
Yes, narrow exceptions exist for death, involuntary conversion, and certain circumstances shown to not be primarily tax-motivated, but these require specific documentation and are evaluated case by case.
Are business partners automatically considered related parties?
Not automatically. The related-party definition centers on family relationships and majority ownership interests, so an unrelated business partner generally falls outside the rule unless another relationship applies.
