Key Facts
- Federal level: Section 1031 currently applies only to exchanges of qualifying real property held for business or investment.
- Federal level: Like-kind describes the nature or character of real property, so improved and unimproved U.S. investment property can often be exchanged.
- Federal level: Replacement property in a deferred exchange generally must be identified within 45 days and received within 180 days or the earlier return due date.
- Federal level: A taxpayer generally cannot receive or control sale proceeds during the exchange; a qualified intermediary is a common safe harbor.
- Federal level: Cash, debt relief, or other non-like-kind property can create currently recognized gain even when the exchange otherwise qualifies.
- Federal level: Form 8824 reports the exchange, calculates recognized gain, and establishes the replacement property’s basis.
What is a 1031 like-kind exchange?
Section 1031 can defer gain or loss when real property held for productive use in a trade or business or for investment is exchanged solely for qualifying like-kind real property held for one of those purposes. Deferral means the tax basis generally carries into the replacement property; it does not permanently erase gain.
The provision is transaction-specific. Property type, holding purpose, taxpayer identity, exchange structure, deadlines, proceeds control, non-like-kind consideration, and reporting must all be tested.
Only real property qualifies today
For exchanges completed after the 2017 statutory change, machinery, vehicles, artwork, equipment, patents, securities, and other personal or intangible property generally do not qualify. Section 1031 is now limited to real property.
Federal regulations define real property through land, improvements, inherently permanent structures, structural components, certain natural products, water and air space, and specified real-property interests. State-law classification is relevant but not always decisive under the federal regulatory tests.
Business or investment use is required
Both relinquished and replacement property must be held for business or investment. Real estate held primarily for sale, including dealer inventory, does not qualify.
A home used solely as a personal residence at the exchange date generally is not section 1031 property. Mixed-use or converted property requires allocation and a fact-based holding-purpose review; section 121 may separately provide a home sale exclusion for qualifying residence gain.
Vacation homes receive special scrutiny. Limited personal use, genuine rental activity, and holding periods can matter under the IRS safe harbor and general investment-intent principles.
What “like kind” means for real estate
Properties are like kind when they share the same nature or character, even if grade or quality differs. Most U.S. real property is broadly like kind to other U.S. real property.
Examples can include exchanging vacant land for an apartment building, rental houses for commercial property, or one long-term leasehold interest for qualifying real estate. Equal value, identical use, or the same property class is not required.
U.S. real property is not like kind to real property outside the United States. A foreign property can potentially be like kind to another foreign real property, subject to all other requirements.
Simultaneous and deferred exchanges
A simultaneous exchange transfers relinquished and replacement properties together. More commonly, a deferred exchange sells the relinquished property first and later acquires replacement property under a written exchange arrangement.
A sale followed by an ordinary purchase does not become an exchange merely because the taxpayer reinvests the proceeds. The documents and restrictions must prevent actual or constructive receipt under the section 1031 regulations.
The 45-day identification deadline
The taxpayer must identify replacement property by midnight of the 45th day after transferring the relinquished property. The period runs on calendar days and generally is not extended for weekends or holidays.
Identification must be written, signed, and delivered to a permitted person involved in the exchange. The property must be described unambiguously, commonly by legal description, street address, or distinguishable name.
The three-property rule permits identification of up to three properties regardless of value. Alternatively, the 200-percent rule permits more properties when their aggregate fair market value does not exceed 200 percent of the relinquished property’s value, with a narrow 95-percent acquired-value rule when those limits are exceeded.
The 180-day exchange deadline
Replacement property must be received by the earlier of 180 days after transfer of the relinquished property or the due date, including extensions, of the federal return for the transfer year. Filing before receiving replacement property can therefore shorten the available period.
The property received generally must be substantially the same as identified. These statutory periods normally cannot be extended by private agreement, although official disaster relief can postpone deadlines for eligible affected taxpayers.
Qualified intermediary safe harbor
A qualified intermediary commonly acquires the relinquished property, holds exchange proceeds, and acquires and transfers replacement property under an exchange agreement. The taxpayer’s rights to receive, pledge, borrow, or otherwise benefit from held funds must be expressly restricted.
The taxpayer, certain relatives, and agents who served the taxpayer within the relevant two-year period can be disqualified from acting as intermediary. Attorneys, accountants, brokers, and real estate agents may therefore fail the independence test unless a regulatory exception applies.
Exchange funds should be placed with the intermediary before the relinquished sale closes. Receiving proceeds and attempting to deposit them afterward generally cannot cure constructive receipt.
Cash, debt relief, and other boot
Money or non-like-kind property received in the exchange is often called boot. Gain is generally recognized up to the value of boot received, limited by realized gain, while loss is not recognized in an otherwise qualifying exchange.
Net debt relief can also be treated as money received. Debt assumed on replacement property, cash paid, and exchange expenses affect the net calculation, so comparing purchase prices alone is incomplete.
Incidental personal property transferred with replacement real estate may be disregarded for the qualified-intermediary safe-harbor restriction when it is customarily transferred with the real estate and does not exceed 15 percent of replacement real-property value. That rule does not make the personal property itself like kind.
Basis and deferred gain
Replacement-property basis generally starts with the basis of relinquished property, adjusted for money paid or received, recognized gain, recognized loss where permitted, and non-like-kind property. This lower carryover basis preserves deferred gain for a later taxable disposition.
Depreciation schedules and recapture attributes require separate analysis. A fully deferred exchange can still alter land-building allocation, recovery periods, and future depreciation calculations.
Related-party exchanges
Special rules apply to exchanges involving related persons. If either party disposes of property received within two years, previously deferred gain or loss can become recognized unless a statutory exception applies.
Using an intermediary does not automatically avoid related-party restrictions, especially when the taxpayer’s replacement property is acquired from a related person. Form 8824 requires related-party information and follow-up filing for two later years.
Reverse and improvement exchanges
A reverse exchange acquires replacement property before relinquished property is transferred. Revenue Procedure 2000-37 provides a qualified exchange accommodation arrangement safe harbor using an exchange accommodation titleholder and a 180-day structure.
An improvement or build-to-suit exchange uses exchange funds for qualifying work while property is held in the exchange structure. Improvements made after the taxpayer receives title generally do not count toward replacement value for the completed exchange.
Reporting on Form 8824
File Form 8824 with the federal return for the year relinquished property was transferred. The form reports property descriptions, dates, related parties, realized gain, recognized gain, deferred gain, and replacement basis.
Recognized gain can also flow to Form 4797, Schedule D, or Form 6252 depending on the property and transaction. Multi-asset exchanges and partial personal use can require statements or worksheet Forms 8824.
Pre-closing checklist
Document business or investment intent, adjusted basis, depreciation, debt, expected sale proceeds, and the proposed replacement criteria. Engage an independent qualified intermediary and sign exchange documents before closing.
Calendar the 45-day and 180-day deadlines, prepare backup properties, and model boot, financing, exchange expenses, basis, and depreciation. Then preserve closing statements, identification notices, intermediary agreements, settlement records, appraisals, and filed Forms 8824.
