1031 Exchange Guide: Rules, Timelines & Examples
A 1031 exchange can defer federal gain when investment or business real estate is exchanged for qualifying like-kind property. Success depends on planning before the sale, protecting the proceeds, and meeting every deadline.

The short answer
How a 1031 exchange works
Section 1031 permits gain deferral when qualifying real property is exchanged rather than sold for cash. In the common delayed structure, a qualified intermediary receives the sale proceeds, the taxpayer identifies replacement property in writing, and the intermediary uses the funds to acquire it within the exchange period.
Step 2
Identify by day 45
Deliver an unambiguous written identification to a permitted party within 45 calendar days.
Step 3
Acquire by day 180
Receive qualifying replacement real estate before the exchange-period deadline.
Step 4
Report the exchange
Report the transaction on IRS Form 8824 and maintain closing, identification, and basis records.
Qualification
1031 exchange rules for real estate
The property, taxpayer, proceeds, identification, and closing must all fit the rules. A valid investment purpose alone does not cure a missed deadline or improper receipt of funds.
- Relinquished and replacement assets are qualifying real property
- Both properties are held for investment or productive use in a trade or business
- U.S. real property is exchanged for U.S. real property
- The same taxpayer generally disposes of and acquires the properties
- A qualified intermediary is engaged before the sale closing
- The taxpayer does not receive or control exchange proceeds
- Replacement property is properly identified in writing by day 45
- Replacement property is received within the exchange period
Investment or business use
A primary residence and property held primarily for resale generally do not qualify. Intent is determined from facts and circumstances; there is no universal minimum holding period in the statute.
Broad real-property standard
Different real-estate types may be like-kind: land can be exchanged for a retail building, for example. The focus is the nature or character of real property, not its grade or quality.
Related-party caution
Related-party transactions have additional rules and anti-abuse limits, including holding-period concerns. Obtain transaction-specific advice before structuring one.
Deadlines
The 45-day and 180-day clocks run together
Both periods begin when the relinquished property transfers. Day 45 is part of the 180-day period; it does not add another 180 days.
Identification period
45 calendar days
Identify replacement property in a signed writing that clearly describes it and is delivered to the intermediary or another permitted party. Weekends and holidays usually do not extend the deadline.
Exchange period
180 calendar days
Receive replacement property by day 180 or, if earlier, the due date of the federal return for the sale year, including extensions. Filing an extension may preserve the full period when the return deadline arrives first.
Concurrent timeline example
Sale closes March 2 → Day 45: April 16 → Day 180: August 29
This example illustrates calendar-day counting only. Confirm the actual dates with your qualified intermediary and tax adviser, including tax-return and federally declared disaster-relief rules.
Identification
Three ways to identify replacement property
The written identification must satisfy one of the regulatory limits. It should be specific enough that the property cannot reasonably be confused with another asset.
Most common
Three-property rule
Identify up to three replacement properties without regard to their fair market value. You do not have to acquire all three.
More options
200% rule
Identify any number of properties if their total fair market value does not exceed 200% of the relinquished property's fair market value.
Narrow safety valve
95% rule
If the first two rules are exceeded, the identification may still qualify if the taxpayer acquires at least 95% of the aggregate fair market value identified.
Full deferral
Replacement value, reinvestment, and boot
A common planning objective is to acquire replacement property of equal or greater value, reinvest all net equity, and replace relinquished debt with equal or greater debt or additional cash. The tax result depends on basis and transaction details, not these shortcuts alone.
Simplified planning framework
Replacement value ≥ sale value; equity reinvested ≥ net equity; debt replaced ≥ debt relieved
Falling short can create cash or mortgage boot. Expenses, credits, liabilities, and basis calculations can change the result, so model the closing statements with a tax adviser.
What counts as boot?
Cash retained, nonqualifying property received, or net debt relief can be boot. Recognized gain is generally limited to realized gain and the value of boot received. A partially taxable exchange can still defer the balance.
Structures
Common types of 1031 exchanges
The delayed exchange is most common, but transaction order and improvement needs can require specialized parking arrangements.
Delayed exchange
Sell first, identify within 45 days, and acquire within the exchange period using a qualified intermediary.
Simultaneous exchange
Transfer the relinquished and replacement properties at substantially the same time, with careful control of proceeds.
Reverse exchange
An exchange accommodation titleholder parks the replacement property before the relinquished property is sold.
Improvement exchange
Parked replacement property is improved with exchange funds before the taxpayer receives it within the exchange period.
Clear answers
Frequently asked questions
Straightforward answers to the questions investors ask most often.
What is a 1031 exchange?
A Section 1031 exchange lets a taxpayer defer recognition of gain when qualifying U.S. real property held for investment or business use is exchanged for other like-kind U.S. real property. It is tax deferral, not tax forgiveness, and the transaction must follow strict structural and timing rules.
How long do I have to complete a 1031 exchange?
You generally have 45 calendar days after transferring the relinquished property to identify replacement property and 180 calendar days to receive it. The 180-day limit can end earlier on the due date, including extensions, of the tax return for the year of the sale. The periods run concurrently.
Do I need a qualified intermediary?
In a typical delayed exchange, engage an independent qualified intermediary before the relinquished-property closing. The intermediary holds sale proceeds and helps document the exchange so the taxpayer does not receive or control the funds.
What property is like-kind for real estate?
For Section 1031, the like-kind standard for real property is broad. An apartment building, retail property, raw land, industrial building, or qualifying leasehold can often be exchanged for another type of U.S. real property if both are held for investment or business use. U.S. and foreign real property are not like-kind to each other.
What is boot in a 1031 exchange?
Boot is non-like-kind value received in the exchange, such as cash, debt relief not offset by replacement debt or cash, or certain personal property. Boot can trigger current taxable gain up to the amount received even when the remainder of the transaction qualifies.
Can I exchange into an NNN property?
A qualifying net lease property can be replacement property if it is U.S. real property acquired and held for investment or business use. Investors often choose NNN assets for potentially predictable income and fewer operating duties, but the tenant, lease, location, basis, and residual value still require diligence.
