Related Party 1031 Exchange Rules
A 1031 exchange with a related party — a close family member or an entity you control — is allowed, but it comes with a special condition that ordinary exchanges don’t have: under IRC §1031(f), both parties must hold their exchanged properties for two years after the last transfer. If either side disposes of its property early, the tax deferral is retroactively lost and the deferred gain is recognized. There is also an anti-abuse rule, §1031(f)(4), that can disqualify related-party deals routed through a qualified intermediary — most notably when you buy your replacement property from a related party who walks away with cash.
What IRC §1031(f) actually says
Congress added subsection (f) to Section 1031 in 1989 to stop basis shifting: related parties swapping a high-basis property into the hands of whichever family member or entity was about to sell, so the group could cash out while paying tax on little or no gain. The fix was a mandatory post-exchange holding period.
The statutory rule in §1031(f)(1) has three triggers. If:
- you exchange property with a related person,
- the exchange qualifies for nonrecognition under §1031, and
- before the date 2 years after the date of the last transfer which was part of such exchange, either the related person disposes of the property it received or you dispose of the property you received,
then “there shall be no nonrecognition of gain or loss under this section to the taxpayer with respect to such exchange.” In plain English: a disqualifying sale by either party inside the two-year window blows up the deferral for the exchange — the gain you deferred becomes taxable, and per the Form 8824 instructions, it must be reported on your return for the year the disqualifying disposition occurs (not by amending the exchange-year return).
Three details investors often miss:
- The clock runs from the last transfer in the exchange, so in a deferred exchange it starts when the final leg closes.
- Both parties are on the clock. Your deferral depends on what your relative or related entity does with the property they received — even though you can’t control it. Written covenants between the parties are common for exactly this reason.
- This two-year rule applies only to related-party exchanges. The general 1031 statute contains no fixed holding period for ordinary exchanges (see the FAQ below on this common myth).
Who counts as a “related party”
§1031(f)(3) defines a related person by cross-reference to IRC §267(b) and IRC §707(b)(1). The most common relationships:
| Category | Related under §267(b)/§707(b)(1) |
|---|---|
| Family | Spouse, brothers and sisters (whole or half blood), ancestors (parents, grandparents), and lineal descendants (children, grandchildren) — per §267(c)(4) |
| Individual ↔ corporation | Corporation more than 50% owned (by value, directly or indirectly) by the individual |
| Individual ↔ partnership | Partnership in which the person owns, directly or indirectly, more than 50% of the capital or profits interest |
| Entity ↔ entity | Two corporations in the same controlled group; a corporation and a partnership with more than 50% common ownership; two partnerships with more than 50% common ownership; certain S corporation pairings |
| Trusts | Grantor and fiduciary; fiduciary and beneficiary; fiduciaries of trusts with the same grantor; and similar trust relationships |
Note who is not on the list: the §267(c)(4) family definition covers only siblings, spouse, ancestors, and lineal descendants — so in-laws, aunts and uncles, nieces and nephews, cousins, and ex-spouses are generally not related parties for this purpose. Indirect and constructive ownership rules apply when entities are involved, so ownership through family members or tiered entities can still make an LLC or partnership “related” to you — this is where a CPA earns their fee.
The dangerous pattern: buying FROM a related party through a QI
The riskiest related-party structure is not a direct swap — it’s a deferred exchange where you sell your property to an unrelated buyer through a qualified intermediary and then use the exchange funds to buy your replacement property from a related party who takes the cash.
That is exactly the fact pattern the IRS shut down in Rev. Rul. 2002-83. In the ruling, taxpayer A sold a low-basis property through a QI and acquired replacement property from related party B, who received the sale proceeds in cash. The IRS held that A was not entitled to nonrecognition under §1031(a), because the arrangement was part of a transaction structured to avoid the purposes of the related-party rules — the anti-abuse backstop in §1031(f)(4). Economically, the family group cashed out of the low-basis property while the taxable gain shifted to the relative’s high basis, which is precisely the abuse §1031(f) targets. Interposing an unrelated QI doesn’t cure it, and the Form 8824 instructions say so expressly: an exchange “made indirectly with a related party includes an exchange made with a related party through an intermediary (such as a QI or an EAT).”
Practical takeaways:
- Buying replacement property from a related party who cashes out is presumptively disqualified under Rev. Rul. 2002-83 and §1031(f)(4).
- Selling your relinquished property to a related party while buying replacement property from an unrelated seller does not involve the same basis-shifting mechanics, and qualified intermediaries generally treat that direction as permissible (see, e.g., Realty Exchange Corporation’s related-party guidance) — but §1031(f)(4) is deliberately broad, so get professional advice before structuring either direction.
- A direct two-party swap with a related person can qualify, provided both sides genuinely hold for two years.
The exceptions: when an early disposition doesn’t kill the deferral
§1031(f)(2) excuses a disposition within the two-year window in three cases:
- Death. The disposition occurs after the death of the taxpayer or the related person. (Death also brings the separate benefit of a stepped-up basis under IRC §1014 for heirs — see 1031 exchanges and inherited property.)
- Involuntary conversion. The property is disposed of in a compulsory or involuntary conversion under IRC §1033 — condemnation, destruction, and the like — as long as the exchange happened before the threat or imminence of the conversion.
- No tax avoidance. You establish “to the satisfaction of the Secretary” that neither the exchange nor the disposition had the avoidance of federal income tax as one of its principal purposes. This is a facts-and-circumstances defense, not a checkbox — don’t count on it as a planning tool.
Reporting: Form 8824, Part II — for three filing years
Related-party exchanges are disclosed to the IRS on Form 8824, the same form used to report every 1031 exchange, but with Part II completed: the related party’s name, relationship to you, and address, plus questions about dispositions.
The instructions then require you to file Form 8824 again for the two years following the year of the exchange, answering each year whether either party disposed of the exchanged property. You can stop the annual filings only if one of the line-11 exceptions applies (death of either party, a post-exchange involuntary conversion, or established non-tax-avoidance). If a disqualifying disposition happens, the deferred gain from line 24 of the original form is reported on your return for the year of the disposition — and the character rules still apply, including any depreciation recapture under IRC §1250 and §1245, plus tax on any boot received in the original deal (see what is boot in a 1031 exchange).
Hypothetical example (illustration only)
Round, hypothetical numbers for illustration — not a real transaction.
A sister swaps her rental duplex (adjusted basis $100,000, value $400,000) for her brother’s rental fourplex of equal value (adjusted basis $350,000). Both defer their gain under §1031 and file Form 8824 with Part II completed.
Fourteen months later, the brother sells the duplex he received for $400,000. Because a party to the exchange disposed of exchanged property before the two-year mark and no §1031(f)(2) exception applies, both siblings lose the deferral: the sister recognizes her previously deferred $300,000 gain ($400,000 value received − $100,000 basis), and the brother recognizes his deferred $50,000 gain ($400,000 − $350,000), each reported for the year of the brother’s sale. Had they both held for two years — or had the early disposition followed a death or condemnation — the deferral would have survived.

One more wrinkle: the two-year rule is federal, but if you exchange across state lines, some states layer their own nonresident withholding and clawback regimes on top — see 1031 exchange rules by state.
Frequently asked questions
No — this is a persistent myth. IRC §1031 contains no fixed minimum holding period for ordinary exchanges between unrelated parties. The statute requires that property be held for productive use in a trade or business or for investment, which is a facts-and-circumstances test of intent, not a stopwatch. The only true two-year rules in this area are the related-party rule of §1031(f) — both parties must hold for two years after a related-party exchange — and the separate vacation-home safe harbor of Rev. Proc. 2008-16, which uses 24 months of qualifying rental use. Many advisors suggest holding a year or two as a prudent margin for the intent test, but that is convention, not statute.
Yes. A swap with a spouse, sibling, parent, or child can qualify under §1031 — but §1031(f) then requires both of you to hold the exchanged properties for two years after the last transfer. If either of you disposes of the property early, both sides recognize their deferred gain in the year of that disposition, unless the disposition follows a death, is an involuntary conversion whose threat arose after the exchange, or you can establish non-tax-avoidance to the IRS's satisfaction.
This is the highest-risk related-party pattern. Under Rev. Rul. 2002-83 and the anti-abuse rule of §1031(f)(4), acquiring replacement property from a related party who receives cash for it generally disqualifies your exchange — even when the deal runs through an unrelated qualified intermediary. Narrow paths may exist, such as where the related seller is completing their own 1031 exchange and receives no cash, but this structure demands professional advice before you commit.
Anyone described in IRC §267(b) or §707(b)(1): your spouse, siblings, ancestors, and lineal descendants; corporations or partnerships in which you own more than 50% directly or indirectly; two entities under more-than-50% common ownership; and various grantor, fiduciary, and beneficiary trust relationships. Notably, in-laws, aunts, uncles, nieces, nephews, cousins, and ex-spouses are generally not related parties under these definitions.
Complete Part II of Form 8824 in the year of the exchange, identifying the related party and your relationship. You must then file Form 8824 again for each of the two following years, reporting whether either party disposed of the exchanged property. If a disqualifying disposition occurs, the deferred gain from line 24 of the original form is reported on your return for the year of the disposition.
