What is a Section 1031 Exchange?
A 1031 exchange is a transaction that allows a real estate investor to exchange qualifying investment or business real property for other like-kind real property while deferring recognition of capital gain that would otherwise arise from the sale.
Named after Section 1031 of the Internal Revenue Code, the provision does not eliminate tax. Instead, it allows the taxpayer to defer capital gains tax by continuing the investment in replacement property rather than cashing out of the investment.
The principle behind Section 1031 is continuity of investment. When an investor disposes of one qualifying property and reinvests the proceeds into another qualifying property, the investor has changed the form of the real estate investment without necessarily extracting the underlying gain.
A properly structured exchange can therefore preserve more capital for reinvestment. However, a 1031 exchange involves strict rules governing the property, taxpayer, exchange proceeds, identification of replacement properties and completion of the transaction.
Missing one of these requirements can result in some or all of the capital gain becoming taxable.
Key Facts: 1031 Exchange
- Real property only: Section 1031 generally applies only to qualifying real property. Personal property such as equipment, vehicles and machinery does not qualify.
- Investment or business use: Both the relinquished property and replacement property must generally be held for investment or for productive use in a trade or business. Property held solely for personal use generally does not qualify.
- 45-day identification deadline: The taxpayer generally has 45 calendar days from the transfer of the relinquished property to identify potential replacement property.
- 180-day exchange period: The replacement property generally must be received by the earlier of 180 days after the relinquished property is transferred or the due date, including extensions, of the taxpayer’s federal income tax return for the year of the transfer. The 45-day and 180-day periods run concurrently.
- IRS reporting: A 1031 exchange is generally reported to the IRS using Form 8824, Like-Kind Exchanges, which records details of the properties, dates, values, liabilities, gain and replacement-property basis.
Who Qualifies for a 1031 Exchange?
A 1031 exchange is not limited to a particular category of professional investor. Individuals and various business entities can potentially qualify provided the taxpayer and transaction satisfy the applicable requirements.
The critical issue is how the property is held.
The relinquished property and replacement property generally need to be held for investment or productive use in a business. An individual landlord exchanging a rental property may therefore qualify, as could a company exchanging commercial premises held for qualifying business purposes.
Ownership also matters. Generally, the same taxpayer that relinquishes the original property should acquire the replacement property. Entity structures involving partnerships, LLCs, trusts and co-owners can therefore introduce additional complexity.
Partnership interests themselves generally do not qualify as like-kind real property. This becomes particularly important when individual partners want different outcomes from the sale of partnership-owned real estate.
There is no general requirement that someone must be a professional real estate investor to qualify for a 1031 exchange. The relevant questions concern the taxpayer, the property, its use and how the exchange transaction is structured.
How Does a 1031 Exchange Work?
In a typical deferred exchange, an investor sells the relinquished property first and subsequently acquires the replacement property. The relinquished property is sold to an unrelated buyer, but the investor does not personally receive the sale proceeds.
Instead, a qualified intermediary normally facilitates the exchange transaction. The intermediary holds or controls the exchange funds under the exchange arrangement while the investor searches for potential replacement properties.
Investors should generally have the exchange structure in place before the relinquished-property closing rather than treating 1031 as something to organise after receiving the sale proceeds.
The basic exchange process is:
- The taxpayer decides to sell a property held for investment or qualifying business purposes.
- A qualified intermediary is appointed before the sale of the relinquished property closes.
- The relinquished property is sold and the exchange proceeds pass to the intermediary.
- The investor identifies potential replacement properties within 45 days.
- The investor selects and contracts to acquire the replacement property.
- The exchange funds are applied towards the acquisition.
- The investor completes the exchange generally within 180 days, subject to the applicable tax-return deadline.
What Properties Qualify for a 1031 Exchange?
Section 1031 now applies to qualifying real property. Following changes made by the Tax Cuts and Jobs Act, personal property such as equipment and machinery no longer receives Section 1031 exchange treatment.
Both the relinquished property and replacement property must generally be held for productive use in a trade or business or for investment.
Property that may qualify for a 1031 exchange includes:
- Single-family rental properties
- Apartment buildings
- Commercial buildings
- Offices and warehouses
- Retail property
- Agricultural land
- Vacant land
- Certain long-term leasehold interests
- Certain qualifying fractional real estate interests
The like-kind requirement is considerably broader than its name suggests. An investor does not need to exchange an apartment for another apartment or an office for another office.
Since 2018, §1031 treatment generally applies only to qualifying real property, rather than the machinery, vehicles, artwork and other personal/intangible property that could potentially qualify under the older regime
For Section 1031 purposes, like-kind generally concerns the nature or character of the real property rather than its grade or quality. A rental house could potentially be exchanged for an apartment building, vacant land for commercial property, or a warehouse for qualifying residential rental property.
However, property primarily held for personal use generally does not qualify. A principal residence usually does not qualify because it is not held for investment or qualifying business use. Property held primarily for immediate resale can also fail the qualifying-use test.
Vacation properties require particular care because personal and investment use can overlap. IRS Revenue Procedure 2008-16 provides a safe harbour for certain dwelling units meeting specified ownership, rental and personal-use requirements.
There is also an important geographical restriction. U.S. real estate is not considered like-kind to real estate outside the United States.
What Does Like-Kind Mean in a 1031 Exchange?
The phrase “like-kind” causes considerable confusion because it does not mean that the investor must exchange one identical property type for another.
For 1031 purposes, like-kind generally refers to the nature or character of qualifying real estate rather than its grade or quality. This creates substantial flexibility.
For example, qualifying like-kind properties could include:
| Relinquished property | Potential replacement property |
|---|---|
| Rental house | Apartment building |
| Commercial building | Rental property |
| Vacant land | Commercial property |
| Farmland | Rental real estate |
| Warehouse | Apartment building |
An investor can therefore use an exchange to diversify or consolidate real estate portfolios rather than simply replacing one property with an identical asset.
There is an important geographic limitation. U.S. real estate is not considered like-kind to real estate located outside the United States.
What Is the 45-Day Rule?
The taxpayer generally has 45 days from the transfer of the relinquished property to identify potential replacement properties.
Identification must be made in writing and must clearly describe the property. In a delayed exchange, the identification is typically delivered to the qualified intermediary or another permitted party involved in the exchange.
The deadline is strict. Investors therefore need to begin their replacement-property search before the relinquished property is sold rather than waiting until the identification period begins.
Three principal identification rules govern how many properties can be selected.
What Is the 180-Day Rule?
Identifying property does not complete the exchange.
The taxpayer generally must acquire the replacement property by the earlier of 180 days after transferring the relinquished property or the due date, including extensions, of the federal income tax return for the year in which the transfer occurred.
The 180 days therefore runs from the same starting point as the 45-day identification period.
This creates a particular consideration for exchanges completed late in the tax year. The tax-return deadline can shorten the available exchange period unless an appropriate filing extension is obtained.
Investors should therefore consider both the property closing timetable and their tax-return timetable when they structure an exchange.
Current IRS Publication 544 says replacement property generally needs to be clearly identified in a signed written document delivered appropriately within the identification period. Real estate can, for example, be identified by street address or legal description.
Three-Property Rule
The investor may identify up to three replacement properties regardless of their combined fair market value.
The investor does not have to purchase all three. This allows an investor to identify a preferred property together with alternatives in case the first acquisition fails.
200% Rule
The 200% rule allows the investor to identify more than three replacement properties provided their combined fair market value does not exceed 200% of the aggregate fair market value of the relinquished property or properties.
This rule can be useful when an investor intends to acquire multiple properties or diversify an existing real estate investment.
95% Rule
The 95% rule can apply where the investor identifies more than three properties and exceeds the 200% valuation threshold.
To satisfy this rule, the taxpayer must ultimately acquire identified replacement properties representing at least 95% of the aggregate fair market value of everything identified.
Because this leaves relatively little room for an acquisition to fail, it can be significantly less forgiving than the other identification methods.
What Is a Qualified Intermediary?
A qualified intermediary, sometimes called an accommodator or exchange facilitator, is an independent party that facilitates a delayed 1031 exchange and controls the exchange proceeds between the sale and purchase transactions.
This arrangement is important because the taxpayer generally cannot take actual or constructive receipt of the sale proceeds and then simply reinvest the proceeds into another property.
The exchange structure should be arranged before the relinquished-property transaction closes.
If the relinquished property is sold and the investor takes control of the cash, the transaction can be treated as a sale rather than a tax-deferred exchange.
The intermediary normally:
- enters into the exchange agreement with the taxpayer;
- receives the proceeds when the relinquished property is sold;
- holds the exchange funds during the identification and acquisition process;
- receives the replacement-property identification;
- transfers funds towards the replacement-property purchase.
Not everyone can act as the intermediary. Certain people with existing relationships to the taxpayer, including particular employees and professional advisers, can be disqualified.
Investors should also assess the financial safeguards used by exchange companies. The intermediary may hold substantial amounts of investor money, so segregation of funds, banking arrangements, insurance and financial controls deserve careful scrutiny.
How Much Money Must You Reinvest?
A 1031 exchange can provide either full or partial tax deferral.
For complete deferral, an investor generally seeks to purchase replacement property with sufficient value and reinvest the net exchange proceeds rather than withdrawing value from the transaction.
Suppose an investor disposes of investment property and retains $100,000 of the proceeds rather than applying that money towards replacement property. The retained amount may constitute boot, potentially making gain taxable to that extent.
The same principle can apply where the investor reduces debt through the transaction without replacing that value through new borrowing or additional cash.
The exchange must therefore be considered as a complete financial transaction rather than simply a comparison between two property addresses.
What Is Boot in a 1031 Exchange?
Boot is cash or other non-like-kind value received through an exchange. Receiving boot does not necessarily cause the entire 1031 exchange to fail. Instead, it can result in gain being recognised to the extent required under the applicable tax rules.
Common examples include:
- Cash boot: cash or exchange proceeds retained by the taxpayer.
- Mortgage boot: net debt relief that is not adequately offset within the transaction.
- Non-like-kind property: property received that does not qualify as replacement real property.
- Certain transaction expenses: some costs paid from exchange proceeds can potentially produce taxable consequences.
This means a taxpayer can complete an otherwise qualifying exchange while still having a current tax liability.
Investors seeking to defer capital gains fully should therefore calculate the transaction before closing rather than assuming that purchasing another property automatically produces complete tax deferral.
What Taxes Can a 1031 Exchange Defer?
A successful 1031 exchange can potentially defer several tax liabilities associated with appreciated investment real estate.
These can include federal capital gains tax, applicable state taxes, the 3.8% Net Investment Income Tax for taxpayers to whom it applies, and qualifying depreciation-related gain.
This is why deferring capital gains can materially increase the amount available for another real estate investment.
Consider an investor with substantial appreciation in an investment property. In a conventional taxable sale, taxes reduce the amount of equity available for the next acquisition. With a qualifying exchange, deferred tax remains embedded in the investment, potentially allowing the investor to acquire a larger replacement asset.
However, deferring capital is different from eliminating tax.
What Happens to the Tax Basis?
Section 1031 preserves the deferred gain through the basis of the replacement property.
Rather than giving the taxpayer a completely fresh tax basis equal to the replacement property’s purchase price, the adjusted basis of the relinquished property carries into the new transaction subject to applicable adjustments.
This carryover mechanism matters because the deferred capital gain has not disappeared. It remains embedded within the replacement property.
If the investor later sells the replacement property in a taxable transaction without another qualifying exchange, previously deferred gain can become recognisable.
Basis also affects future depreciation. Investors should therefore calculate the replacement-property basis carefully and retain documentation throughout the exchange.
How a 1031 Exchange Is Reported
A taxpayer generally reports a 1031 exchange to the IRS using Form 8824, Like-Kind Exchanges.
The form captures information including:
- descriptions of the properties involved;
- acquisition and transfer dates;
- related-party information where applicable;
- fair market values;
- liabilities;
- realised and recognised gain;
- basis of the replacement property.
Reporting is therefore not simply confirmation that an exchange occurred. It establishes how the transaction is treated for tax purposes and how the basis of the replacement property is calculated.
Investors should retain the exchange agreement, identification notice, settlement statements, qualified-intermediary records, financing documents and other transaction documentation.
State reporting requirements can also apply independently of federal IRS rules.
Benefits of a 1031 Exchange
The principal benefit of a 1031 exchange is the ability to defer capital gains tax while keeping more investment capital deployed in real estate.
Depending on the taxpayer and transaction, an exchange may defer qualifying federal capital gains tax, applicable depreciation-related gain, the Net Investment Income Tax and state taxation.
But tax deferral is only one potential benefit.
A 1031 exchange can also allow investors to:
- Increase purchasing power. Capital that might otherwise have been paid in tax remains available for investment.
- Diversify. One large property can potentially be exchanged for several smaller investment properties.
- Consolidate. Multiple properties can potentially be exchanged into one larger asset.
- Change property sectors. Investors can move between qualifying residential, commercial, industrial or land investments.
- Change geography. Qualifying property can generally be exchanged between different U.S. states.
- Reduce management responsibility. Investors may move from actively managed property into qualifying passive structures such as a DST.
- Reposition a portfolio. An investor can potentially change income, growth, location and management characteristics without first crystallising all deferred gain.
For investors intending to remain invested in real estate, these characteristics can make Section 1031 an important portfolio-management tool rather than simply a tax strategy.
Risks and Common Ways an Exchange Fails
The existence of a tax advantage does not make a 1031 exchange risk-free.
One of the clearest risks is missing either the 45-day identification deadline or the applicable 180-day completion deadline which can prevent the intended deferral.
Other common risks include:
- taking actual or constructive receipt of the sale proceeds;
- failing to appoint the intermediary before the relinquished-property closing;
- acquiring property that does not satisfy the qualifying-use requirement;
- failing to identify replacement property correctly;
- financing delays preventing closing;
- receiving unexpected boot;
- changing taxpayer ownership incorrectly;
- selecting an unsuitable qualified intermediary;
- failing to document the exchange properly.
There is also a more fundamental investment risk. The 45-day deadline can pressure investors into buying whatever replacement property is available. An investor may therefore successfully defer $150,000 of tax but subsequently lose considerably more by purchasing an overpriced or poor-quality property.
You should also consider what happens when a 1031 exchange fails. This is important because you don’t want to be caught out if this does happen.
The exchange should serve the investment strategy. The investment strategy should not be sacrificed simply to preserve the exchange.
What Types of 1031 Exchange Are Available?
The conventional delayed exchange is only one type of exchange.
Simultaneous Exchange
In a simultaneous exchange, the relinquished property and replacement property are transferred at essentially the same time.
This resembles the original concept behind the like-kind exchange, but matching the timing of two modern real estate transactions can make simultaneous exchanges difficult in practice.
Delayed Exchange
A delayed exchange, also called a deferred 1031 exchange, occurs when the relinquished property is transferred before the replacement property is acquired.
This is the common type of 1031 exchange and uses the 45-day identification and 180-day completion framework.
Reverse Exchange
A reverse exchange is used where an investor needs to acquire replacement property before disposing of the existing property.
In simple terms, a reverse exchange is the opposite of the standard forward sequence.
A properly structured reverse 1031 exchange commonly involves an Exchange Accommodation Titleholder that temporarily holds, or “parks”, title to property under the safe-harbour framework established by Revenue Procedure 2000-37.
Improvement Exchange
An improvement or construction exchange allows exchange funds to be used towards qualifying improvements to replacement real estate before the taxpayer takes final ownership.
The structure can be useful where the available replacement property does not initially have sufficient value or where the investor wants to adapt it for a particular investment strategy.
However, improvements intended to count towards the exchange generally need to be completed and incorporated into the qualifying real property within the applicable exchange timeframe.
Replacement Property Options
A 1031 exchange provides considerably more flexibility than exchanging one building for another identical building.
Direct Real Estate
The simplest option is acquiring another directly owned qualifying property.
This might involve exchanging:
- a rental house for an apartment building;
- vacant land for a warehouse;
- commercial property for residential rental property;
- farmland for another qualifying real estate investment;
- an office building for industrial property.
Because the like-kind definition for qualifying real estate is broad, investors can use the exchange to change asset class, market, management requirements and investment strategy.
Multiple Properties
An investor does not necessarily have to exchange one property for one replacement property.
One relinquished property can potentially be exchanged for several replacement properties, provided the identification, valuation, reinvestment and other Section 1031 requirements are satisfied.
Conversely, multiple relinquished properties can potentially feed into the acquisition of a larger replacement asset.
This flexibility can make exchanges useful for portfolio diversification and consolidation.
The identification rules become particularly important where multiple properties are involved because the Three-Property, 200% and 95% rules determine how potential acquisitions can be designated.
Delaware Statutory Trusts
A Delaware Statutory Trust (DST) can provide another replacement-property option.
Under Revenue Ruling 2004-86, an interest in a DST structured as described in the ruling may qualify for 1031 treatment when the other requirements are satisfied.
DSTs typically hold institutional real estate and provide investors with fractional beneficial interests.
They can appeal to investors who want to reduce direct property-management responsibilities or who need access to replacement-property opportunities within a limited exchange timeframe.
However, a DST is not simply a convenient way to complete an exchange. Investors surrender significant control and face sponsor, property, financing, concentration and liquidity risks. The investment itself must therefore be evaluated independently of its eligibility for 1031 tax deferred treatment.
When a 1031 Exchange May Not Make Sense
A 1031 exchange is not automatically the best decision simply because an investor has a taxable gain.
It may not make sense when the investor needs access to the sale proceeds, intends to leave real estate altogether or cannot find a suitable replacement property.
An exchange may also be questionable when the immediate tax liability is relatively small compared with the transaction costs, complexity and restrictions created by the exchange.
Most importantly, investors should not overpay for replacement property simply to avoid tax.
Suppose paying tax on a conventional sale would cost $100,000. Purchasing an unsuitable property for $150,000 more than its reasonable value merely to preserve the exchange would make little economic sense. Tax efficiency is only valuable when the underlying investment remains sound.
Here are some other examples of when a 1031 may not make sense:
- The replacement investment is poor.
- Liquidity matters more than deferral.
- The tax liability is relatively modest.
- The investor cannot find suitable replacement property within the timetable.
- The investor wants to exit real estate exposure altogether.
- The proposed replacement doesn’t fit their risk, income or management objectives.
A taxpayer should therefore consider the investment objective first:
Would I still want to own this replacement property if there were no 1031 tax benefit?
If the answer is no, the exchange deserves reconsideration.
2. Can I realistically meet the identification/acquisition timetable?
3. Does the replacement improve my portfolio rather than merely defer tax?
4. Do I understand the liquidity, financing and management implications?
5. Have I involved the appropriate tax/legal/exchange professionals before the transaction reaches the point where mistakes become irreversible?
Before you start a 1031 exchange, answer these five questions
- Is the relinquished property genuinely held for investment/business use?
- Have you engaged a QI before closing?
- Do you already know your replacement-property strategy?
- Can you realistically identify within 45 days?
- Are you exchanging because the replacement investment is good, or only because you don’t want to pay tax?
1031 Exchange FAQs
Does a 1031 exchange eliminate capital gains tax?
No. A 1031 exchange generally defers qualifying tax rather than eliminating it. Deferred gain is carried into the replacement property and may become taxable when that property is eventually sold in a taxable transaction.
How long do I have to identify replacement property?
You generally have 45 calendar days after transferring the relinquished property to identify potential replacement property.
How long do I have to complete a 1031 exchange?
The replacement property generally must be received by the earlier of 180 days after transferring the relinquished property or the due date, including extensions, of the applicable federal tax return.
Do I have 45 days plus 180 days?
No. The two periods run concurrently. The 180-day period begins when the relinquished property is transferred, not when the 45-day identification period ends.
Does the replacement property have to be the same type?
No. Qualifying real property has a broad like-kind definition. For example, an investor may potentially exchange rental property for commercial property or vacant land for an apartment building.
Can I buy more than one replacement property?
Yes. An investor can potentially acquire multiple replacement properties, although the identification rules and other requirements still apply.
Can I keep some of the cash?
Potentially, but retained cash can constitute boot and cause some of the gain to become currently taxable.
Can I do a 1031 exchange on my primary residence?
A property used solely as a primary personal residence generally does not qualify because Section 1031 applies to qualifying real property held for investment or productive business use.
Do I need a qualified intermediary?
A qualified intermediary is normally used for a conventional delayed 1031 exchange to prevent the taxpayer from taking actual or constructive receipt of the exchange funds.
What happens if my 1031 exchange fails?
If the transaction fails to qualify, the intended tax deferral can be lost and the gain from the disposition of the relinquished property may become taxable. Partial exchanges can have different consequences where some of the transaction still qualifies.
Before you start a 1031 exchange, answer these five questions
- Is the relinquished property genuinely held for investment/business use?
- Have you engaged a QI before closing?
- Do you already know your replacement-property strategy?
- Can you realistically identify within 45 days?
- Are you exchanging because the replacement investment is good, or only because you don’t want to pay tax?
