What Is a 1031 Exchange and How Does It Work for Commercial Real Estate?
A 1031 exchange, named after Internal Revenue Code Section 1031, allows commercial real estate investors to defer capital gains taxes by reinvesting sale proceeds into a "like-kind" replacement property. Instead of paying federal capital gains tax (up to 20%), depreciation recapture (25%), and the 3.8% Net Investment Income Tax on a property sale, you roll the full equity into your next investment.
For commercial property owners, this mechanism is one of the most powerful wealth-building tools available. A seller who would owe $400,000 in combined taxes on a $2 million gain can instead deploy that entire amount into a larger, higher-performing asset. Over multiple exchange cycles, investors routinely grow portfolios from single properties into diversified commercial holdings worth tens of millions.

The IRS requires that both the relinquished property (the one you sell) and the replacement property (the one you buy) be held for productive use in a trade, business, or investment. Personal residences and properties held primarily for resale (fix-and-flip) do not qualify. Commercial properties including office buildings, retail centers, industrial warehouses, multifamily apartments, and self-storage facilities all qualify as like-kind to one another.
What Are the Critical Timelines Every Investor Must Follow?
The 1031 exchange process operates under two strict, non-negotiable deadlines that begin the moment your relinquished property closes. Missing either deadline disqualifies the entire exchange, with no extensions granted, even for weekends, holidays, or unforeseen circumstances.
The 45-Day Identification Period starts on the day you close the sale of your relinquished property. Within this window, you must formally identify potential replacement properties in writing to your Qualified Intermediary. The identification must include the legal description or street address of each property and be signed by you.
The 180-Day Exchange Period is your outer boundary. You must close on one or more of your identified replacement properties within 180 calendar days of selling the relinquished property, or by your tax return due date (including extensions) for the year of the sale, whichever comes first.
The Two Critical 1031 Exchange Deadlines
Day 0: Sale Closes
Relinquished property closes. Proceeds go directly to Qualified Intermediary. Both clocks start the next day.
Day 1 to 45: Identification Period
Formally identify up to 3 replacement properties in writing. Submit signed notice to QI before midnight on Day 45.
Day 46 to 180: Acquisition Period
Complete due diligence, secure financing, and close on identified replacement property before Day 180 expires.
Tax Filing: Form 8824
Report the exchange on IRS Form 8824 with your tax return for the year the relinquished property was sold.
These timelines run concurrently, not sequentially. Day 1 begins the day after closing on your relinquished property. If you sell on March 1, your identification deadline is April 15 (Day 45) and your exchange deadline is August 28 (Day 180).
One critical planning note: if you sell a property in October, November, or December, your 180-day window may extend past April 15 of the following year. In that case, you must file a tax extension to preserve the full 180 days. Failing to file that extension effectively shortens your exchange period.
How Do the Three Identification Rules Limit Your Replacement Options?
The IRS provides three alternative rules for identifying replacement properties. You only need to satisfy one of these rules, but understanding all three lets you build maximum flexibility into your exchange strategy.
The Three-Property Rule is the simplest and most commonly used. You may identify up to three replacement properties regardless of their combined fair market value. You are not required to acquire all three. Many investors identify three properties and close on just one or two.
The 200% Rule allows you to identify more than three properties, but the combined fair market value of all identified properties cannot exceed 200% of the value of the relinquished property. If you sold a property for $2 million, you could identify five properties as long as their total value does not exceed $4 million.
The 95% Rule removes limits on the number or value of identified properties, but you must actually acquire at least 95% of the aggregate value of all properties identified. This rule is rarely used because failing to close on even one identified property can disqualify the exchange.
For most commercial investors selling a property and looking to acquire a replacement asset, the Three-Property Rule provides the best balance of flexibility and safety.
What Role Does a Qualified Intermediary Play in Your Exchange?
A Qualified Intermediary (QI), also called an exchange accommodator, is the independent third party who holds your sale proceeds during the exchange period. This is not optional. If you touch the funds at any point, even briefly, the exchange fails.
Qualified Intermediary Selection Checklist
| Criteria | Why It Matters | Red Flag |
|---|---|---|
| Segregated Escrow Accounts | Prevents commingling of your funds with other clients | Pooled or omnibus accounts |
| Fidelity Bond Coverage | Protects you if the QI commits fraud or theft | No bond or coverage under $5 million |
| E&O Insurance | Covers errors in exchange documentation or process | No professional liability insurance |
| Commercial Experience | Understands complex structures, reverse and improvement exchanges | Only handles residential exchanges |
| Fee Transparency | No surprise charges at closing | Vague pricing or hidden wire fees |
| Written Exchange Agreement | Defines roles, responsibilities, and timelines clearly | No formal agreement before closing |
The QI enters into an Exchange Agreement with you before closing. At closing, the sale proceeds transfer directly from the title company to the QI's escrow account. When you are ready to purchase your replacement property, the QI wires the funds to the closing agent. You never have constructive receipt of the money.
Who cannot serve as your QI? The IRS disqualifies anyone who has acted as your agent within the prior two years. This includes your attorney, accountant, real estate broker, or any employee of those professionals. The QI must be a truly independent party.
When selecting a QI, evaluate these factors: segregated escrow accounts (your funds should never be commingled), fidelity bond and errors-and-omissions insurance, experience with commercial transactions, and transparent fee structures. QI fees typically range from $750 to $3,000 for standard forward exchanges and $5,000 to $15,000 for reverse or improvement exchanges.

How Do You Calculate Boot and What Triggers a Taxable Event?
"Boot" is any non-like-kind property or value received in an exchange that triggers partial tax liability. Even in a well-structured 1031 exchange, receiving boot means you will owe capital gains tax on that portion. Understanding boot is essential to achieving full tax deferral.
Cash boot occurs when you do not reinvest all sale proceeds into the replacement property. If you sell for $3 million, have $500,000 in exchange expenses, and only invest $2.3 million in a replacement property, the remaining $200,000 is taxable cash boot.
Mortgage boot occurs when the debt on your replacement property is less than the debt on your relinquished property. If you had a $1.5 million mortgage on the sold property but only take on a $1.2 million loan for the replacement, the $300,000 difference is mortgage boot.
To achieve full deferral, you must meet two requirements simultaneously:
- Reinvest all net equity from the sale
- Acquire replacement property with equal or greater debt (or offset the difference with additional cash)
Use our commercial mortgage calculator to model replacement property financing scenarios and ensure you eliminate boot before closing.
What Is the Difference Between Forward, Reverse, and Improvement Exchanges?
The standard forward exchange (sell first, buy second) is the most common structure, but it is not the only option. When market conditions or timing constraints make a forward exchange impractical, reverse and improvement exchanges offer powerful alternatives.
Forward Exchange: You sell the relinquished property first, and the QI holds the proceeds while you identify and acquire replacement property within the 45/180-day deadlines. This is the simplest and least expensive structure.
Reverse Exchange: You acquire the replacement property before selling the relinquished property. An Exchange Accommodation Titleholder (EAT) takes title to either the replacement property or the relinquished property through a special-purpose LLC. You then have 180 days to complete the sale of the relinquished property. Reverse exchanges cost more ($15,000 to $25,000 in accommodator fees) and require bridge financing since you temporarily own both properties.
Improvement Exchange (Build-to-Suit): You use exchange funds to make improvements on the replacement property before taking title. The EAT holds title while renovations or construction occur. The improved value of the property at the time you take title counts toward your exchange value. This is particularly useful when the available replacement property needs significant work to match the relinquished property's value.
Both reverse and improvement exchanges require the transaction to be completed within 180 days. The EAT cannot hold property beyond that window.
Which Commercial Property Types Qualify as Like-Kind?
The "like-kind" requirement for real property is broader than most investors realize. Under the Tax Cuts and Jobs Act of 2017, Section 1031 applies exclusively to real property (personal property exchanges were eliminated), but the definition of qualifying real property is expansive.
Like-Kind Commercial Property Exchange Matrix
| Relinquished Property | Valid Replacement Examples | Notes |
|---|---|---|
| Retail Strip Center | Office building, warehouse, apartments, raw land | Any real property held for investment qualifies |
| Industrial Warehouse | Self-storage, medical office, mixed-use, farmland | Different asset class is fine |
| Multifamily Apartments | Hotel, retail center, industrial park, NNN lease | Different property type is fine |
| Office Building | Multifamily, DST interest, ground lease, raw land | DST interests qualify as real property |
| Raw Land | Any improved commercial property | Land to building exchanges are common |
| Leasehold (30+ years) | Fee simple interest in any real property | Leasehold must be 30 years or more to qualify |
Any interest in real property held for investment or business use qualifies as like-kind to any other interest in real property held for investment or business use. This means you can exchange a retail strip center for an industrial warehouse, a multifamily apartment complex for a medical office building, or raw land for a fully developed commercial property.
Key qualifications to remember: the property must be within the United States (you cannot exchange domestic property for foreign real estate), it must be held for investment or productive business use, and it must be real property as defined by the IRS (which includes inherently permanent structures, structural components, and certain intangible interests like easements and leaseholds of 30 years or more).
Investors looking to diversify their commercial holdings through a 1031 exchange can explore various permanent loan programs to finance the replacement property at competitive long-term rates.
What Are the Most Common 1031 Exchange Mistakes That Disqualify Investors?
Exchange failures are more common than they should be, and nearly all of them are preventable. Understanding these pitfalls before you begin the process is critical to protecting your tax deferral.
Top 5 Exchange Killers to Avoid
Missing the 45-day identification deadline is the most frequent cause of failed exchanges. Market conditions, indecision, and due diligence delays all contribute. Start identifying potential replacement properties the moment you list your relinquished property for sale, not after it closes.
Touching the proceeds in any form disqualifies the exchange immediately. This includes having the title company send funds to your account "temporarily," using exchange funds to pay non-qualified expenses, or directing the QI to pay personal obligations.
Failing to match values results in taxable boot. Investors sometimes forget that both the purchase price and the debt on the replacement property must equal or exceed those of the relinquished property. Use our DSCR calculator to evaluate replacement property financing and ensure you meet these thresholds.
Related-party transactions face additional scrutiny. While you can exchange property with a related party under Section 1031, both parties must hold their respective properties for at least two years after the exchange. If either party disposes of their property within that window, the exchange is disqualified retroactively.
Inadequate documentation can also sink an exchange. The identification notice must be precise, properly dated, and delivered to the QI before midnight on Day 45. Verbal identifications, late faxes, or notices sent to the wrong party do not count.

How Can You Combine a 1031 Exchange With Other Exit Strategies?
A 1031 exchange does not exist in isolation. Sophisticated commercial investors integrate exchanges into broader portfolio strategies that maximize returns and minimize lifetime tax obligations.
Exchange and Refinance: After completing a 1031 exchange, you can refinance the replacement property to pull out cash tax-free. The IRS does not consider refinance proceeds as boot or a taxable event, provided the refinance occurs after the exchange is fully closed. Many investors exchange into a property, stabilize it, then refinance to access liquidity without triggering gains.
Exchange to DST (Delaware Statutory Trust): Investors who want passive income without management responsibility can exchange into a DST, which qualifies as like-kind real property. DSTs offer fractional ownership in institutional-quality commercial assets and are popular among retiring investors or those transitioning out of active management.
Serial Exchanges and the Step-Up: By executing 1031 exchanges throughout your investment career and holding the final property until death, your heirs receive a stepped-up basis equal to the property's fair market value at the time of inheritance. This effectively eliminates all deferred capital gains permanently. This strategy, sometimes called "swap till you drop," is one of the most tax-efficient wealth transfer mechanisms in real estate.

What Does the 1031 Exchange Process Look Like Step by Step?
A successful 1031 exchange requires coordination between your real estate broker, attorney, QI, lender, and tax advisor. Here is the complete process from start to finish.
Complete 1031 Exchange Timeline: Start to Finish
Pre-Exchange (60 to 90 Days Before)
Engage CPA and attorney. Research replacement properties. Select Qualified Intermediary. Add exchange cooperation clause to sale agreement.
Closing Day (Day 0)
Close on relinquished property. QI receives proceeds directly from title company. Document exchange agreement execution.
Identification Phase (Day 1 to 45)
Evaluate replacement candidates. Complete preliminary due diligence. Submit formal written identification to QI before Day 45 deadline.
Acquisition Phase (Day 46 to 180)
Finalize financing with lender. Complete inspections and appraisals. QI funds replacement property closing before Day 180.
Post-Exchange Compliance
File Form 8824 with tax return. Maintain all exchange records for 7+ years. Begin replacement property management or refinance planning.
Pre-Exchange Planning (60 to 90 days before sale): Engage your CPA and attorney to confirm exchange eligibility. Begin researching replacement properties. Interview and select a Qualified Intermediary. Structure the sale agreement with exchange cooperation language.
Sale and Exchange Initiation (Day 0): Close on the relinquished property. Sale proceeds transfer directly to the QI. The 45-day and 180-day clocks begin the following day.
Identification Period (Days 1 to 45): Conduct due diligence on replacement candidates. Submit formal written identification to the QI before Day 45 expires. Apply for acquisition financing on target properties.
Acquisition Period (Days 46 to 180): Negotiate purchase terms, complete inspections, and finalize financing. Coordinate with the QI to fund the replacement property closing. Close on one or more identified properties before Day 180 expires.
Post-Exchange Compliance: File IRS Form 8824 with your tax return for the year of the exchange. Maintain records of the exchange agreement, identification notices, closing statements, and QI correspondence for at least seven years.

Frequently Asked Questions About 1031 Exchanges?
Can I do a 1031 exchange on a property I have held for less than one year? The IRS does not specify a minimum holding period, but most tax advisors recommend holding the relinquished property for at least 12 to 24 months to demonstrate investment intent. Properties held for short periods may be classified as "held for sale" rather than "held for investment," which disqualifies them.
Can I exchange into a property in a different state? Yes. Like-kind exchanges work across state lines within the United States. However, some states (California, Oregon, Montana, and Massachusetts) require withholding or special reporting when you sell property in their jurisdiction and exchange into property in another state.
What happens if I cannot find a replacement property within 45 days? If you fail to identify any replacement property by Day 45, the exchange fails entirely. The QI will return the funds to you, and you will owe capital gains taxes for the year of the sale. There are no extensions or exceptions to this deadline.
Can I live in a 1031 exchange property? Not immediately. The replacement property must be held for investment or business use. However, IRS Revenue Procedure 2008-16 provides a safe harbor for converting a 1031 exchange property to a personal residence after holding it as a rental for at least two years with specific usage limitations.
Is there a limit on how many 1031 exchanges I can do? No. There is no lifetime limit on the number of 1031 exchanges you can complete. Many investors execute serial exchanges over decades, continuously deferring gains while upgrading their portfolios.
Do I need to use the same lender for my replacement property? No. You can use any lender for the replacement property. However, coordinating with a lender experienced in 1031 exchange timelines is critical because closing delays can cause you to miss the 180-day deadline. Contact Clearhouse Lending for financing that aligns with exchange timelines.
What are the tax implications if my exchange fails? If the exchange fails at any point, the transaction is treated as a standard sale. You will owe federal capital gains tax (0% to 20% depending on income), depreciation recapture tax (25%), state income tax, and potentially the 3.8% Net Investment Income Tax.
Can a partnership or LLC do a 1031 exchange? Yes, but the entity that holds title to the relinquished property must be the same entity that acquires the replacement property. Individual partners cannot exchange their partnership interest, as partnership interests are explicitly excluded from Section 1031. One workaround is a "drop and swap" where the partnership distributes the property to individual partners who then execute individual exchanges.
