If you sell investment property in the U.S., a 1031 exchange can defer capital gains and depreciation recapture taxes. But the rules are strict, the timelines are short, and one mistake can blow the entire exchange. This guide explains 1031 exchanges in 2026 with clear steps, examples, and a checklist you can actually use.
Summary A 1031 exchange lets you defer taxes by swapping one investment property for another. You must use a qualified intermediary, identify replacement properties within 45 days, and close within 180 days. You cannot touch the sale proceeds.

Quick Answer: What Is a 1031 Exchange?
A 1031 exchange is a U.S. tax strategy that allows you to defer capital gains and depreciation recapture taxes when you sell investment property, as long as you reinvest the proceeds into another qualifying property.
It is a deferral, not a forgiveness. The tax bill is postponed until you sell without another exchange.
The EXCHANGE Framework
Use EXCHANGE to remember the core rules:
E = Exchange investment property
X = eXclude personal residences
C = Close within 180 days
H = Hire a qualified intermediary
A = Identify within 45 days
N = No cash or control of proceeds
G = Greater or equal value
E = Exchange rules are strict
Which Properties Qualify
1031 exchanges apply only to investment or business real estate. Personal residences do not qualify.
Examples that qualify:
- Rental properties
- Commercial buildings
- Vacant land held for investment
Examples that do not qualify:
- Your primary residence
- Property held primarily for resale (house flips)
- Inventory or dealer property
Key Timelines: 45 Days and 180 Days
You must meet both deadlines:
- Identify replacement property within 45 days of closing the sale of the relinquished property.
- Close on the replacement property within 180 days of that same closing.
These deadlines are strict. Missing them usually ends the exchange.
The Role of the Qualified Intermediary
You cannot touch the sale proceeds. A qualified intermediary (QI) must hold the funds and facilitate the exchange.
Important:
Your QI cannot be your attorney, accountant, or anyone who has worked with you in the last two years.
Like-Kind Property: What It Really Means
In real estate, "like-kind" is broad. You can exchange:
- Single-family rental for a multi-family property
- Land for an apartment building
- Commercial property for a rental home
The key is that both properties are held for investment or business use.
Identification Rules: The 3-Property and 200% Tests
During the 45-day identification window, you must follow strict rules:
- 3-Property Rule: Identify up to three properties of any value.
- 200% Rule: Identify any number of properties as long as their total value does not exceed 200% of the property you sold.
- 95% Rule: If you exceed the 200% limit, you must close on 95% of the value identified.
These rules prevent overly broad identification lists.
Boot and Taxable Gain
If you receive cash or non-like-kind property, that amount is called boot and is taxable.
Common boot sources:
- Cash left over after purchase
- Reduction in mortgage debt without equal replacement
To fully defer taxes, you must reinvest all proceeds and replace debt with equal or greater debt or cash.
Depreciation Recapture and 1031 Exchanges
A 1031 exchange defers both capital gains and depreciation recapture. The recapture does not disappear; it carries forward into the replacement property.
For the recapture basics, see Depreciation Recapture Explained.
Reverse and Improvement Exchanges
Reverse exchange: You buy the replacement property before you sell the old one. This requires a special structure and an exchange accommodation titleholder.
Improvement exchange: You use exchange proceeds to improve the replacement property before the exchange closes. The improvements must be completed within the 180-day window to count.
Step-by-Step 1031 Exchange Process
- Sell your relinquished property.
- QI receives the proceeds.
- Identify replacement properties within 45 days.
- Perform due diligence and close within 180 days.
- Complete exchange paperwork with your QI.

Common Scenarios and Examples
Example 1: Simple Exchange
Sell rental for $600,000 with $200,000 gain.
Buy replacement for $650,000 using all proceeds.
Result: Tax deferred on full gain.
Example 2: Boot Received
Sell rental for $500,000, buy replacement for $470,000.
$30,000 is left over and becomes taxable boot.
Example 3: Debt Reduction Boot
Old mortgage: $300,000
New mortgage: $250,000
$50,000 debt reduction may be taxable unless offset with cash.
Delaware Statutory Trusts (DSTs) as Replacements
Some investors use DSTs as replacement properties to simplify management or access larger assets. DSTs can qualify for 1031 exchanges, but they have limited control and unique risks. Always review the offering carefully.
Common Mistakes and Audit Risks
- Missing the 45-day identification deadline
- Taking possession of sale proceeds
- Using a disqualified intermediary
- Exchanging property held primarily for resale
- Failing to replace debt properly
Recordkeeping Checklist
Keep the documents that prove compliance:
- Exchange agreement and QI contract
- Identification letter with dates
- Closing statements for both properties
- Debt payoff and new financing documents
- Replacement property purchase contract
State Tax Considerations
Some states require additional filings or do not fully conform to federal 1031 rules. If you exchange across states, track state-specific tax obligations and withholding requirements.
FAQs
Can I use a 1031 exchange for a vacation home?
Only if the property is held for investment and meets IRS guidelines for rental use.
Do I have to buy one property?
No. You can identify multiple properties, but you must follow identification rules and close within 180 days.
Is a 1031 exchange worth it for a small gain?
It depends on the tax savings versus the transaction costs. See When a 1031 Exchange Makes Sense.
