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)

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

How does a 1031 exchange save taxes?

Hypothetical example

Round numbers. For current guidance, see IRS like-kind exchange guidance. 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

What are the strict deadlines for completing a 1031 exchange?

A 1031 exchange imposes two non-negotiable deadlines. You have 45 calendar days from the date you sell the relinquished property to identify potential replacement properties in writing to the qualified intermediary. You must close on the replacement property within 180 calendar days of the sale (or by the due date of your tax return, including extensions, whichever comes first). These deadlines cannot be extended, even for weekends or holidays. If you miss either deadline, the entire exchange fails and the full gain becomes taxable in the year of the original sale.

Can I offset capital gains with capital losses from other investments?

Yes. Capital losses first offset capital gains of the same type (short-term losses against short-term gains, long-term against long-term), then any remaining net loss offsets gains of the other type. If net capital losses exceed capital gains, you can deduct up to $3,000 of the excess against ordinary income ($1,500 if married filing separately). Unused losses carry forward indefinitely to future tax years, maintaining their character (short-term or long-term). The wash sale rule (IRC 1091) prevents you from claiming a loss if you repurchase substantially identical securities within 30 days before or after the sale. Tax-loss harvesting before year-end is a common strategy to realize losses that offset gains elsewhere in the portfolio.

Will selling one rental free losses under the REPS election?

Maybe not. Suspended passive losses are freed only when you dispose of your entire interest in the activity in a fully taxable sale. A real estate professional who elects to treat all rental real estate as one activity has arguably made the whole portfolio that activity, so selling a single building out of it may not release losses suspended in earlier years.

The election is a statement attached to your original return, and it binds that year and every later year in which you qualify as a real estate professional, unless your facts and circumstances change materially. Without it, each property is its own activity and you’d have to materially participate in each one. For an investor stacking properties through sequential exchanges, that’s a real tradeoff to weigh before filing.

Exchanges don’t help here either. A 1031 exchange generally doesn’t free suspended losses, because the gain isn’t fully recognized. The clearest release is a fully taxable sale of the entire activity to an unrelated buyer.
