1039 Exchange: Did You Mean 1031?

Short answer: if you searched for a 1039 exchange, you almost certainly mean a 1031 exchange. The U.S. Code source listed below shows Section 1039 as repealed, while Section 1031 is the real-property exchange rule headed Exchange of real property held for productive use or investment.

The correction is not just spelling. A 1031 exchange can postpone recognition of gain when eligible real property is exchanged for like-kind real property, but it has strict property, timing, cash, and reporting rules. Use this page to translate the typo into the rule you actually need to evaluate.

Is there a 1039 exchange?

For the real estate tax-deferral topic investors usually have in mind, the answer is no. The relevant Code section is 1031, not 1039. A U.S. Code PDF in the primary sources includes the bracketed entry 1039. Repealed.

That means a search for 1039 exchange should be redirected to Section 1031 analysis. If an advisor, closing statement, or article uses 1039 where the topic is a real estate like-kind exchange, ask whether they meant Section 1031. The tax result depends on the actual statute and regulations, not the typo.

What Section 1031 actually does

Section 1031 provides that no gain or loss is recognized when real property held for productive use in a trade or business or for investment is exchanged solely for real property of like kind that will also be held for productive use in a trade or business or for investment. That is the core federal nonrecognition rule in IRC Section 1031.

The IRS describes the same idea in practical terms: a properly executed like-kind exchange can postpone recognition of gain by shifting the basis of property sold to like-kind replacement property. See the IRS answer on nontaxable exchange or like-kind exchange.

That is deferral language, not a promise that every sale is tax-free. The question is whether the property, exchange structure, deadlines, and reporting line up with Section 1031.

Property that can fit Section 1031

For 2018 and later years, the 2025 Instructions for Form 8824 state that Section 1031 like-kind exchange treatment applies only to exchanges of real property held for use in a trade or business or for investment, other than real property held primarily for sale.

The IRS real estate tax tips page says the same rule in a taxpayer-facing way: Section 1031 now applies only to exchanges of real property and not to exchanges of personal or intangible property. It also states that real property held primarily for sale still does not qualify. See IRS like-kind exchanges real estate tax tips.

The post-2017 limitation matters because older discussions of like-kind exchanges may mention assets that no longer fit the current rule. The IRS page states that, effective January 1, 2018, exchanges of machinery, equipment, vehicles, artwork, collectibles, patents, other intellectual property, and intangible business assets generally do not qualify as like-kind exchanges.

Delayed-exchange timing

A delayed exchange is an exchange where, under an agreement, the taxpayer transfers relinquished property and later receives replacement property. The current Treasury regulations describe that deferred-exchange structure in 26 CFR part 1.

For a delayed exchange, the timing rules are central. Section 1031 treats property as not like-kind property if it is not identified on or before the day that is 45 days after the taxpayer transfers the relinquished property.

The replacement-property receipt deadline is also not simply 180 days in every calendar situation. The statute requires receipt by the earlier of 180 days after the taxpayer transfers the relinquished property or the due date, determined with regard to extension, for the taxpayer’s return for the transfer year. In other words, a tax-return due date can shorten the practical exchange period unless an extension applies.

This page is not saying every possible exchange structure universally requires a qualified intermediary. It is saying that when the exchange is delayed, the statutory identification and receipt dates have to be built into the transaction calendar from the beginning.

If you receive cash or other non-like-kind property

A 1031 exchange can be partly taxable. Section 1031 says that if an otherwise qualifying exchange includes other property or money, the recipient recognizes gain, but not in excess of the money and fair market value of the other property received. The Form 8824 instructions similarly state that if cash or other non-like-kind property is involved, gain is recognized to the extent of the other property and money received, while a loss is not recognized.

Here is a hypothetical illustration using round numbers:

Item	Amount
Sale price of relinquished real property	$700,000
Adjusted basis	$420,000
Realized gain	$280,000
Cash or non-like-kind property received	$60,000
Recognized gain	$60,000
Deferred gain	$220,000

The arithmetic is simple: $700,000 minus $420,000 equals $280,000 of realized gain. If $60,000 of cash or other non-like-kind property is received, the recognized gain is $60,000 because it is less than the $280,000 realized gain. The remaining $220,000 is the gain not recognized in the current exchange calculation. This example is hypothetical and ignores exchange expenses, depreciation details, state tax, and any facts not shown.

Reporting the corrected exchange

The reporting form is also a clue that the correct term is 1031, not 1039. The IRS states that Form 8824, Like-Kind Exchanges, is used to report a like-kind exchange. The 2025 Instructions for Form 8824 say to use Parts I, II, and III of Form 8824 to report each exchange of business or investment real property for real property of a like kind.

Those instructions also state that Form 8824 figures the amount of gain deferred as a result of a like-kind exchange, and that Part III figures gain required to be reported in the current year if cash or property that is not like-kind is involved.

Practical checklist after searching for 1039 exchange

If you arrived here through the typo, the next step is to evaluate the actual Section 1031 requirements:

Confirm the transaction involves real property, not personal or intangible property.
Confirm both the relinquished and replacement properties are held for business or investment use.
Exclude real property held primarily for sale from the 1031 analysis.
Calendar the 45-day identification deadline from the transfer of the relinquished property.
Calendar the final receipt deadline as the earlier of 180 days after transfer or the tax-return due date for the transfer year, including extensions.
Model any cash or other non-like-kind property received.
Report the exchange on Form 8824 with the return for the exchange year.

That is the useful translation of the search term: not 1039, but a 1031 exchange that must satisfy the current real-property, timing, and reporting rules.
