Step 1: Sale vs. Exchange
Estimate realized gain, depreciation recapture exposure, capital gain exposure, and the approximate tax that may be deferred through an exchange.
1031 Exchange Basics
A 1031 exchange involves more moving parts than most investors expect — timing deadlines, replacement-property requirements, financing coordination, and the right professionals working together. This section covers the major concepts in plain English.
Core concept
A 1031 exchange allows many real estate investors to defer gain from the sale of qualifying investment or business real estate when they reinvest into other qualifying real estate. Since the Tax Cuts and Jobs Act of 2017, Section 1031 generally applies only to real property, not personal property such as vehicles, equipment, furniture, or artwork. The tax is generally deferred, not erased. The replacement property usually carries forward the tax history of the relinquished property, which is why basis and depreciation matter.
Who needs to be involved?
Below are the professionals commonly involved in a 1031 exchange.
Investor / Exchanger
The taxpayer selling the old property and acquiring replacement property. The same taxpayer generally needs to stay consistent through the exchange.
Qualified Intermediary
The QI helps structure the exchange, holds exchange funds, prepares exchange documents, and helps prevent the exchanger from taking control of proceeds.
CPA / Tax Advisor
Calculates gain, basis, depreciation recapture, state tax exposure, and whether the exchange makes sense after tax consequences are considered.
Real Estate Broker
Helps locate replacement property, analyze values, manage timing pressure, negotiate terms, and keep the acquisition search moving.
Attorney
Important when ownership structure, entities, partnership issues, title, drop-and-swap planning, or legal risk are involved.
Lender
Needed when replacement debt must be arranged quickly. Financing delays can create exchange failure risk even when the property is identified on time.
What is boot?
In a 1031 exchange, “boot” generally refers to value received by the exchanger that is not like-kind replacement real estate. Boot may cause part of an otherwise tax-deferred exchange to become taxable.
Two common planning concerns are cash boot and mortgage boot. Cash boot may occur when the exchanger keeps some sale proceeds instead of reinvesting them. Mortgage boot may occur when debt is reduced and not offset with new debt or additional cash. The actual tax treatment is fact-specific and should be reviewed with a qualified intermediary and tax advisor.
Understanding depreciation recapture
Many investors focus only on capital gains tax, but depreciation can also matter. If a property has been depreciated, some of the gain may be subject to depreciation recapture rules when the property is sold. This can make the estimated tax exposure larger than a simple “sale price minus purchase price” calculation suggests.
This planner separates estimated depreciation recapture exposure from remaining capital gain exposure so users can see why their CPA’s tax estimate may differ from a simple capital-gains-only calculation.
The three planning rules most investors need to understand
1. Buy equal or greater value
To aim for full deferral, the replacement property value generally needs to be equal to or greater than the relinquished property value, subject to transaction-specific details.
2. Reinvest net proceeds
Cash retained outside the exchange may create taxable cash boot.
3. Replace debt or add cash
If debt is reduced, the exchanger may need to add cash to avoid mortgage boot or partial taxable gain.
Key timeline
Relinquished property closes
The clock starts when the old property sale closes.
Identification deadline
Replacement property must generally be identified in writing by this deadline.
Acquisition deadline
The replacement property must generally be acquired within the exchange period.
Replacement property identification rules
Replacement property does not necessarily have to be one property. Some exchanges involve multiple replacement properties, but identification rules and timing requirements can become important very quickly.
Three-property rule
An exchanger may commonly identify up to three potential replacement properties, regardless of their total value. This is often the simplest framework to understand.
200% rule
More than three properties may sometimes be identified if the combined value of the identified properties does not exceed 200% of the relinquished property value.
95% exception
In some situations, broader identification may still work if the exchanger ultimately acquires at least 95% of the identified value. This is less common and should be reviewed carefully.
Other exchange structures investors may encounter
Delayed exchange
The most common structure: sell first, identify replacement property, then buy within the required timeline.
Reverse exchange
Replacement property is acquired before the old property sells. This is more complex and typically more expensive. These structures commonly involve a parking arrangement or exchange accommodation titleholder (EAT), where a separate entity temporarily holds title during part of the exchange process.
Improvement / build-to-suit exchange
Exchange funds may be used toward improvements under strict structure and timing rules. These structures commonly involve a parking arrangement or exchange accommodation titleholder (EAT), where a separate entity temporarily holds title during part of the exchange process.
DST or TIC interests
Some investors use Delaware Statutory Trust (DST) or Tenants in Common (TIC) structures as replacement-property options, especially when they want passive ownership or need replacement-property options quickly near exchange deadlines. TIC ownership structures can also create exchange-planning complexity on the relinquished-property side when co-owners have different goals or timelines.
Drop and swap
Advanced pre-exchange ownership restructuring sometimes considered before an exchange, often involving partnership or co-ownership changes. These arrangements may receive significant IRS scrutiny, particularly when restructuring appears primarily exchange-motivated. Attorney and CPA guidance is strongly recommended.
Swap and drop
Advanced post-exchange restructuring concept sometimes discussed after replacement property acquisition. Still complex and fact-specific, but generally viewed differently from pre-exchange restructuring arrangements. Professional legal and tax guidance is essential.
Common exchange complications
Many exchanges run into trouble because of ownership structure, timing pressure, debt replacement shortfalls, or a misunderstanding of how deferred gain actually works. These are issues worth raising early with your QI, CPA, attorney, broker, and lender — before a deal is under contract.
Partial exchanges
A 1031 exchange does not always have to be fully tax deferred to remain valid. Some investors intentionally keep cash, buy smaller replacement property, or reduce debt. These situations may create partial taxable gain or boot rather than causing the entire exchange to fail.
Carryover basis
A 1031 exchange generally defers tax rather than eliminating it. The replacement property usually carries forward part of the tax history and deferred gain from the relinquished property, which can affect future depreciation, gain calculations, and eventual sale decisions.
Same taxpayer rule
The taxpayer selling the relinquished property generally needs to be the same taxpayer acquiring the replacement property. Partnerships, LLCs, trusts, and ownership restructuring can create complications that should be reviewed before the sale closes.
Constructive receipt
One of the most common exchange mistakes is allowing the seller to receive or control sale proceeds directly. Exchange funds are generally handled through the qualified intermediary to help preserve exchange treatment.
Qualified intermediary selection
Not all QIs operate the same way. Before choosing one, ask about experience, bonding, insurance coverage, how exchange funds are held, references, and fee structure.
Tax reporting and records
1031 exchanges are commonly reported on IRS Form 8824 and may require detailed supporting records. Investors should maintain organized documentation related to basis, depreciation, improvements, closing statements, exchange agreements, and replacement acquisitions.
When a 1031 exchange may not be worth it
A 1031 exchange is not always the best move, even when the tax deferral looks attractive on paper. It may make less sense when the gain is limited, replacement-property options are weak, ownership structure issues add significant complexity, or the investor values liquidity more than continued tax deferral. Investors should also be cautious about overpaying for replacement property simply because identification and closing deadlines are approaching.
