Learn how a 1031 like-kind exchange can defer real estate gain, including eligible property, 45- and 180-day rules, basis, boot and California filings.
A 1031 exchange, also called a like-kind exchange, occurs when qualifying real property held for business or investment is exchanged for other qualifying real property. When Section 1031 requirements are satisfied, gain can be deferred until a later taxable disposition.
It is tax deferral, not a tax-free sale followed by an unrestricted purchase. The exchange structure, property purpose, timing, control of funds, value received, basis, and reporting all matter.
Current federal Section 1031 treatment generally applies only to real property held for productive use in a trade or business or for investment. Qualifying real property can be broadly like-kind within the United States. An apartment building can generally be exchanged for vacant investment land, retail property, or another rental even though the properties differ in grade or use.
These generally do not qualify:
Intent and actual use matter. Simply renting a personal home briefly or planning an immediate resale does not guarantee investment-property treatment.
Many exchanges are deferred rather than direct swaps. A typical sequence is:
The 45-day and 180-day periods begin on the same transfer date and run concurrently. Weekends and holidays generally do not extend them. Filing a return before the exchange is complete can shorten the practical deadline if no extension is obtained.
If the seller actually or constructively receives the proceeds, the transaction can become a taxable sale. A qualified intermediary generally holds the exchange funds and acquires and transfers the relevant property rights under the exchange arrangement.
The intermediary must be selected before the relinquished-property closing. Tax advice, title, financing, and due diligence remain separate responsibilities.
Jordan sells qualifying rental property for $800,000. Its adjusted basis is $500,000, so simplified realized gain is $300,000 before selling costs and other adjustments.
Jordan uses a properly structured exchange to acquire replacement investment real estate for $800,000 and receives no cash or other non-like-kind property. If all requirements are met, the $300,000 gain may be deferred.
The replacement property does not generally receive an $800,000 tax basis. A simplified carryover calculation is:
$800,000 replacement value − $300,000 deferred gain = $500,000 replacement basis
This lower basis preserves the deferred gain for a later transaction. Additional cash paid, liabilities, exchange expenses, depreciation, and multiple-property allocations can change the actual calculation.
Cash, non-like-kind property, or net debt relief received in an exchange is commonly called boot. The taxpayer generally recognizes gain up to the amount of qualifying boot received, limited by realized gain. A loss generally is not recognized in a partially qualifying exchange.
Replacing one mortgage with another does not by itself determine whether the exchange is fully deferred. Liabilities, cash, values, and exchange expenses must be reconciled.
Deferred gain carries into the replacement property through basis rules. Existing depreciation history also affects the exchange and later sale. Replacement property can contain exchanged basis plus additional basis, with depreciation sometimes computed in separate layers.
Section 1031 does not eliminate depreciation-related gain; it can defer qualifying recognition. A later taxable sale, conversion, failed exchange, or related-party transaction can produce current tax.
Form 8824 reports the exchanged properties, dates, related-party information, realized gain, recognized gain, deferred gain, and replacement basis. Other results can flow to Form 4797, Schedule D, Form 8949, partnership or S-corporation returns, depreciation schedules, and state forms.
The same taxpayer generally must relinquish and acquire the properties, subject to entity rules. Ownership changes near an exchange can create qualification issues.
California generally permits like-kind exchange deferral for qualifying real property, but it continues to track California-source deferred gain. When California property is exchanged for out-of-state replacement property and California gain is deferred, Form FTB 3840 is generally required for the exchange year and each later year until the California-source deferred gain or loss is recognized.
The filing obligation can continue after the taxpayer moves, exchanges the replacement property again, or no longer otherwise has a California return requirement. Maintain the original California basis, deferred gain allocation, later exchanges, and dispositions.
Retain purchase and closing statements, depreciation schedules, basis records, exchange agreement, qualified-intermediary agreement, assignments, identification notice and proof of delivery, replacement-property closing records, financing statements, appraisals, expense allocations, Forms 8824 and FTB 3840, and all later disposition records.
Heath Income Tax can model realized and recognized gain, verify basis and depreciation, coordinate tax reporting with the exchange team, and maintain federal and California deferred-gain schedules.
Is a 1031 exchange the same as a like-kind exchange?
Yes. "1031 exchange" refers to Internal Revenue Code Section 1031; "like-kind exchange" describes the transaction.
Can I sell first and choose a property later?
A deferred exchange can work, but it must be structured before closing and the strict identification and receipt deadlines must be met.
Must the replacement be the same type of building?
No. U.S. business or investment real estate is often broadly like-kind to other U.S. business or investment real estate.
Can I use a 1031 exchange for my home?
A home held solely for personal use generally does not qualify. Mixed-use, converted, or former rental property requires a fact-specific Section 1031 and Section 121 analysis.
Does a 1031 exchange avoid California tax forever?
Not necessarily. California can continue tracking deferred California-source gain, especially through FTB 3840 when California property is exchanged for out-of-state property.
