The short answer
Usually yes. The disallowance in section 1031(f)(1) is aimed at a taxpayer who exchanges property with a related person, and when your relative simply buys the property for cash while your replacement comes from an unrelated seller, nothing of yours is swapped for anything of theirs and no basis moves between family members. You still answer "Yes" on Form 8824 line 7, complete Part II, and file the form again for each of the next two years. A direct swap of deeds with a relative is the other case entirely, and puts both of you on a two-year clock.
At a glance
| What the statute reaches | An exchange of property with a related person (§1031(f)(1)) |
|---|---|
| Why a cash sale differs | The buyer owned nothing before, so no high-for-low basis swap occurs |
| Form 8824 line 7 | "Yes" for related parties direct or indirect, including through a QI |
| Part II entries | Related party's name, relationship and identifying number on line 8 |
| Filing tail | File Form 8824 for the 2 years following the exchange year |
| Bargain pricing | §267(a)(1) disallows any loss on a sale to a person listed in §267(b) |
| Direct deed swap | Both parties must hold 2 years from the last transfer (§1031(f)(1)(C)) |
Cashing out a relative who owned nothing before the deal is not the transaction section 1031(f) was written to stop
Section 1031(f)(1) withdraws nonrecognition where a taxpayer "exchanges property with a related person" and either side disposes within two years. Its target, spelled out in the House report quoted in Rev. Rul. 2002-83, is related parties trading high-basis property for low-basis property in anticipation of a sale, so that the family cashes out of the low-basis asset without paying for it.
Selling to your daughter for cash and buying a replacement from a stranger does not do that. She brought money, not property, so there is nothing of hers for your basis to attach to and nothing of yours to shelter her later sale.
IPX1031 summarises the Service's private rulings on the point, reporting that an exchange in which relinquished property goes to a related buyer through an unrelated intermediary while the replacement comes from an unrelated seller will likely be respected even if the related buyer resells within two years, because only the taxpayer owned property beforehand. Private letter rulings bind only their recipients under section 6110(k)(3), so treat them as the Service's thinking rather than as authority you can cite.
Line 7 is still a "Yes", and the form comes back for two more filing seasons
The Instructions for Form 8824 treat an exchange as made indirectly with a related party where it runs through an intermediary such as a qualified intermediary or an exchange accommodation titleholder, or where either side transacts through a disregarded entity. A cash sale to a relative through your QI is squarely inside that description.
Part II then wants the related party's name, their relationship to you and their identifying number on line 8, which means asking your brother-in-law's company or your son for a taxpayer identification number before the closing rather than in April.
The paperwork does not end with the exchange year either. Two further Forms 8824 follow, one for each of the next two tax years, each asking whether anyone sold; what those follow-up filings ask walks through the questions and the stopping points.
Swapping deeds with your brother is the version that starts a two-year clock on both of you
When each of you conveys real property to the other, section 1031(f)(1) applies directly, and a disposition by either party within two years of the last transfer strips nonrecognition from the original exchange.
Publication 544 runs the numbers on a brother-and-sister swap and shows the sting: an early onward sale by one sibling reopens the other sibling's exchange as well, pulling a six-figure deferred gain onto a return that person thought was closed years earlier.
Note what that example does to someone who was not party to the later sale. Your sibling's tax year is changed by your decision to sell, which is why the mechanics belong in the swap agreement; the two-year rule sets out the exceptions.
Price it at arm's length, because a family discount costs you on both sides of the exchange
Sell below market and you shrink the proceeds the qualified intermediary receives, which lowers the value you can replace and leaves more of the sale price outside the exchange. Whether you reinvest the whole sale price or just the gain explains why the target is measured against price, not profit.
Hypothetical figures. A duplex appraises at $900,000 and you let your son have it for $800,000 with a $250,000 adjusted basis. Your exchange now has to replace $800,000 of value and $800,000 of equity to defer fully, and the $100,000 you handed over never reaches the qualified intermediary, so it can neither buy replacement property nor shelter gain.
A discount can also be recharacterised in part as a gift, with its own return and its own consequences for your relative's basis. That is a separate regime from section 1031 and is worth pricing before you sign.
If the property is worth less than your basis, section 267(a)(1) is unforgiving: no deduction is allowed for a loss on a sale or exchange, directly or indirectly, between persons described in section 267(b). Should you exchange when selling at a loss covers the alternative.
Why experienced advisers still ask the related buyer to hold for two years
Section 1031(f)(4) is a purpose test, not a list. It denies section 1031 to "any exchange which is part of a transaction (or series of transactions) structured to avoid the purposes of this subsection," and courts read it by looking at the tax result to the related parties as a unit.
A relative who resells quickly invites the argument that the family always intended a cash exit and used your exchange to get there. The cheapest insurance is a buyer who intends to keep the property, documented by a loan, a lease or a move-in rather than by assurances.
If a disposition does happen and you believe it was not tax-driven, Form 8824 line 11c lets you check the box and attach an explanation. Confirm with your CPA or attorney before you rely on it, because the burden of establishing that to the IRS is yours.
- Get an appraisal or broker opinion dated before the contract, not after the closing.
- Have the related buyer fund the purchase from their own resources or from a bank, rather than from a note you carry.
- Keep the qualified intermediary agreement and the assignment of the sale contract in the file, because they show the sale ran through the exchange.
- Diary the two Form 8824 filings; the tail is easy to miss when nothing has happened.
Related questions
Does my relative have to hold the property for two years?
The statute imposes that duty in a direct exchange with a related person. In a cash purchase from you, the Service's private rulings suggest it is not required, but a fast resale invites a section 1031(f)(4) argument, which is why a two-year hold is the common recommendation.
Can I sell to an LLC my children own?
Yes, and it is still a related-party disclosure. Entities are related under section 267(b) or 707(b)(1) at more than 50 percent ownership, and the attribution rules can pull your children's interests to you; see who counts as a related party.
My buyer is my tenant and also my nephew. Does that change anything?
A nephew is not within the family list in section 267(c)(4), so this is an ordinary sale unless an entity relationship brings him in. Selling a rental to your tenant covers the rest.
Can I take a small amount of cash out of a sale to my son?
Yes, on the same terms as any other exchange: cash retained is boot and is taxed up to your realised gain. See what boot is.
Is a sale to my own revocable trust a related-party sale?
A grantor trust you control is generally treated as you for income tax purposes, so it is a title change rather than a sale; buying the replacement in a revocable trust takes up the same-taxpayer question that actually decides it.
What happens if I skip Part II?
The exchange is not automatically disqualified, but you have filed an incomplete return and removed the record that supports your position later; what records to keep for a 1031 audit covers the file to build.
