The IRC 1031 like-kind exchange is the single most powerful tax deferral tool available to real estate investors, and it has been used to build some of the largest real estate portfolios in the country without paying a dollar of capital gains tax. Under IRC 1031, no gain or loss is recognized when property held for productive use in a trade or business or for investment is exchanged solely for property of like kind that is also held for productive use or investment. “Like kind” for real property is extremely broad: an apartment building can be exchanged for raw land, a commercial office can be exchanged for a single-family rental, and a farm can be exchanged for a shopping center. The only requirement is that both properties are real property held for business or investment use (not personal use and not dealer/inventory property). The deferred gain is preserved through a substituted basis in the replacement property: the replacement property’s basis equals the relinquished property’s basis, adjusted for any boot (non-like-kind property or cash) received or paid in the exchange.

✓Key takeaway

IRC 1031 exchange requirements:

Requirement	Details
Property type	Real property only (post-TCJA)
Held for	Business use or investment (not personal use, not dealer inventory)
Like-kind definition	Any real property for any other real property (extremely broad)
Qualified intermediary (QI)	Must use a QI to hold proceeds; taxpayer can’t touch the funds
45-day identification period	Must identify replacement property within 45 calendar days of relinquished property sale
180-day exchange period	Must close on replacement property within 180 calendar days of relinquished property sale
Same taxpayer	The same taxpayer (or entity) must sell the relinquished and acquire the replacement
No related-party restriction workaround	Related-party exchanges require a 2-year holding period (IRC 1031(f))

Identification rules:

Rule	Limit
3-property rule	Identify up to 3 replacement properties (regardless of value)
200% rule	Identify any number of properties, but total FMV cannot exceed 200% of relinquished property FMV
95% rule	Identify any number/value, but must acquire at least 95% of aggregate FMV identified
Most common	3-property rule (simplest)

What qualifies as like-kind real property:

Relinquished Property	Replacement Property	Like Kind?
Apartment building	Office building	Yes
Raw land	Shopping center	Yes
Single-family rental	Warehouse	Yes
Farm	Hotel	Yes
Commercial condo	Residential rental	Yes
Primary residence	Rental property	No (personal use property excluded)
Vacation home (personal use)	Rental property	No (unless primarily rented, not personal)
Property held for resale (dealer)	Any property	No (inventory excluded)
US real property	Foreign real property	No (domestic only)

How does a 1031 exchange save taxes?

Hypothetical example

Round numbers. An investor owns a rental property purchased for $500,000 ten years ago, now worth $1,200,000. Total depreciation claimed: $150,000.

Tax without 1031 exchange (straight sale):

Item	Amount
Sale price	$1,200,000
Original basis	$500,000
Accumulated depreciation	($150,000)
Adjusted basis	$350,000
Total gain	$850,000
Depreciation recapture (IRC 1250, 25%)	$150,000 x 25% = $37,500
Capital gain ($700,000 at 23.8%)	$166,600
Total federal tax	$204,100

Tax with 1031 exchange (no boot):

Item	Amount
Sale price of relinquished property	$1,200,000
Purchase price of replacement property	$1,400,000
Additional cash invested (boot paid)	$200,000
Gain recognized	$0
Tax	$0

Replacement property basis:

Item	Amount
FMV of replacement property	$1,400,000
Minus: deferred gain	($850,000)
Plus: boot paid	$200,000
Basis in replacement property	$550,000

The deferred gain lives inside the reduced basis. If the replacement property is later sold for $1,800,000:

Item	Amount
Sale price	$1,800,000
Basis	$550,000
Gain	$1,250,000 (includes the $850,000 deferred gain + $400,000 new appreciation)
Option	Do another 1031 exchange (defer again)

Boot scenarios:

Scenario	Tax Consequence
Replacement property costs less than relinquished (cash boot received)	Gain recognized to the extent of boot received
Mortgage boot (replacement has smaller mortgage)	Net mortgage relief = boot received
Replacement property costs more (boot paid)	No gain recognized; boot paid increases replacement basis

Example with boot:

Item	Amount
Relinquished property sale price	$1,200,000
Replacement property purchase price	$1,000,000
Cash boot received	$200,000
Gain recognized (lesser of boot or realized gain)	$200,000
Tax on $200,000 recognized gain	~$47,600 (23.8%)
Deferred gain	$650,000

Sequential 1031 exchanges (lifetime deferral + step-up at death):

Transaction	Gain Deferred	Cumulative Deferred Gain
Exchange 1 (age 35): sell $500K property	$200,000	$200,000
Exchange 2 (age 45): sell $1.2M property	$500,000	$700,000
Exchange 3 (age 55): sell $2.5M property	$1,000,000	$1,700,000
Exchange 4 (age 65): sell $4M property	$1,500,000	$3,200,000
Death (age 80): property worth $8M	Step-up to $8M FMV (IRC 1014)	$0
Total capital gains tax paid		$0
Tax deferred then eliminated		$3,200,000 x 23.8% = $761,600

Common 1031 exchange mistakes:

Mistake	Consequence
Taxpayer receives sale proceeds directly (no QI)	Exchange fails; entire gain taxable
Miss the 45-day identification deadline	Exchange fails
Miss the 180-day closing deadline	Exchange fails
Identified property falls through, no backup identified	Exchange fails on that portion
Exchange between related parties without 2-year hold	Gain recognized retroactively
Attempting to exchange personal residence	Not eligible (must be business or investment use)
Converting replacement property to personal use too quickly	IRS may challenge (no minimum holding period specified, but 2+ years is safest)

Reverse exchange (Rev. Proc. 2000-37):

Step	Details
1. Exchange Accommodation Titleholder (EAT) acquires replacement property	EAT holds title temporarily
2. Taxpayer sells relinquished property	Within 180 days
3. EAT transfers replacement property to taxpayer	After relinquished property closes
4. Cost	Higher (EAT fees, additional closing costs)
5. When to use	Hot market where replacement property must be secured before relinquished property sells
