Exchanging property with a related party is legal under Section 1031, but it comes with a condition most other exchanges don't carry: both the investor and the related party generally have to hold their respective properties for at least two years after the exchange, or the deferred gain gets recaptured and taxed retroactively. Related-party exchanges show up often in family-owned Long Island real estate, where a parent, sibling, or closely held entity is a natural counterparty, and that familiarity is exactly why the rule exists. New York's income tax treats the eventually recognized gain the same as ordinary income once deferral ends, which raises the stakes of getting a related-party structure wrong compared with a state that taxes capital gains at a lower rate.
Who Counts as a Related Party
The tax code's related-party definitions are broader than most investors expect. Family members including siblings, spouses, ancestors, and descendants count, as does a corporation, partnership, or trust in which the investor holds more than a 50 percent interest. An LLC an investor controls, or a family limited partnership set up for estate planning, generally counts as related as well. Two Long Island investors who happen to be business partners in an unrelated venture do not automatically count as related parties under this rule, but the ownership thresholds catch more entity structures than people assume when they're setting one up for other reasons.
The Two-Year Holding Requirement
Section 1031(f) requires that both the investor and the related party hold onto their respective properties, the ones received in the exchange, for at least two years following the exchange's completion. If either party disposes of their property before that two-year period runs, the original exchange is disqualified retroactively, and the gain that was deferred becomes taxable in the year of the early disposition, not the year of the original exchange. This applies even if the early disposition itself would otherwise have been a legitimate, unrelated sale.
Where the Traps Usually Hide
The classic problem case is an investor exchanging into a low-basis property already owned by a related party, effectively swapping high basis for low basis within the family, and then having the related party sell shortly afterward, converting what would have been a straightforward taxable sale by the related party into an attempt to shift the tax burden. The IRS treats this pattern as an abuse of the exchange rules regardless of how the paperwork is structured. A less obvious trap involves a related-party qualified intermediary or accommodation titleholder; using an entity that's too closely tied to the investor for either role can undermine the independence the exchange depends on, separate from the two-year holding issue entirely.
What Still Works Within the Rule
A straightforward exchange between related parties, where both sides genuinely intend to hold their new property for the full two years, is permitted and Long Island families use it, particularly when restructuring ownership of adjoining or complementary parcels within a family portfolio, such as a multigenerational Nassau retail block or a set of Suffolk industrial buildings split between siblings after an estate transition. Exchanges where the related party isn't a counterparty at all, meaning the investor exchanges with an unrelated third party and simply uses a related-party entity as the qualified intermediary's independent counterpart on paper, generally don't trigger the two-year rule, since that rule applies to exchanges of property between related parties specifically, not to every transaction that happens to touch a family entity somewhere in the chain.
Common 1031 Exchange Questions
Can you do a 1031 exchange with your sibling or parent?
Yes, but both parties generally need to hold their respective properties for at least two years after the exchange. Disposing of either property sooner can retroactively disqualify the exchange and trigger tax on the deferred gain.
What happens if the related party sells their property within two years?
The original exchange is generally disqualified, and the deferred gain becomes taxable in the year of that early disposition, not the year the exchange took place. This applies to the investor's deferred gain even though the early sale was made by the related party, not the investor.
Does an LLC you control count as a related party?
Often yes. Entities in which the investor holds more than a 50 percent ownership interest, including many LLCs, partnerships, and closely held corporations, generally count as related parties under Section 1031(f), even if the entity was formed for unrelated reasons.
Are there any exceptions to the two-year holding requirement?
Limited exceptions exist, including situations involving death, involuntary conversion, or circumstances the IRS determines were not primarily aimed at avoiding tax. These exceptions are narrow and fact-specific, so they warrant a CPA's review rather than an assumption that a particular situation qualifies, especially before an early sale is scheduled on the assumption that an exception will apply.
Can a family member act as your qualified intermediary?
No, a qualified intermediary has to be independent, and a related party generally cannot serve in that role. Using a closely tied entity for the intermediary or accommodation titleholder role can undermine the exchange separately from the two-year related-party rule.
