The Section 1031 like-kind exchange is one of the most powerful wealth-building tools in real estate, allowing investors to defer capital gains tax indefinitely by rolling proceeds from one property into another. The tax code under IRC 1031 permits the deferral of ALL gain (capital gain, depreciation recapture, and NIIT) when investment or business real property is exchanged for other investment or business real property of “like kind.” In practice, “like kind” is extremely broad for real estate: an apartment building can be exchanged for raw land, a commercial office can be exchanged for a rental house, and a farm can be exchanged for a strip mall. The exchange must be structured through a qualified intermediary (QI) who holds the sale proceeds (the taxpayer can’t touch the money), the replacement property must be identified within 45 days, and the acquisition must close within 180 days. When done correctly, the entire gain is deferred. When the taxpayer eventually dies, the deferred gain is permanently eliminated through the stepped-up basis under IRC 1014, making the “defer until death” strategy one of the most significant tax advantages in the code.

✓Key takeaway

1031 exchange requirements:

Requirement	Details
Property type	Real property held for investment or business use (NOT personal residence, NOT inventory/dealer property)
Like-kind standard	Any real property for any other real property (extremely broad)
Qualified intermediary (QI)	Must be used; taxpayer cannot receive or control the proceeds
45-day identification period	Replacement property must be identified in writing within 45 days of relinquished property closing
180-day exchange period	Replacement property must be acquired within 180 days of relinquished property closing
Equal or greater value	Replacement must equal or exceed the relinquished property’s sale price
Equal or greater debt	Debt on replacement must equal or exceed debt on relinquished (or difference is “boot”)
Boot (taxable)	Cash received or debt relief not replaced = taxable gain

Identification rules (45-day window):

Rule	What It Allows
3-property rule	Identify up to 3 replacement properties (regardless of value)
200% rule	Identify any number of properties whose combined FMV doesn’t exceed 200% of the relinquished property’s sale price
95% rule	Identify any number at any value, but must acquire at least 95% of the total identified value

How does a 1031 exchange save tax over multiple exchanges?

Hypothetical example

Round numbers. An investor bought a rental property for $300,000 in 2010. It’s now worth $800,000. The investor has taken $100,000 in depreciation, reducing the adjusted basis to $200,000.

Selling without a 1031 exchange:

Item	Amount
Sale price	$800,000
Adjusted basis	$200,000
Total gain	$600,000
Depreciation recapture ($100,000 x 25%)	$25,000
Remaining LTCG ($500,000 x 23.8%)	$119,000
Total federal tax	$144,000
Net proceeds	$656,000

Selling with a 1031 exchange into a $900,000 replacement property:

Item	Amount
Sale price (relinquished)	$800,000
Proceeds held by QI	$800,000 (less closing costs)
Replacement property price	$900,000
Additional cash from investor	$100,000
New mortgage on replacement	$400,000
Federal tax	$0 (all gain deferred)
Amount working for investor	$800,000 (full sale proceeds reinvested)

Basis of replacement property:

Item	Amount
Purchase price of replacement	$900,000
Minus: Deferred gain	($600,000)
Plus: Additional cash invested	$100,000
Adjusted basis of replacement	$400,000

The replacement property starts with a lower basis ($400,000 instead of $900,000), so the deferred gain will be recognized if this property is later sold without another 1031 exchange.

Chain of exchanges over a career:

Exchange	Relinquished	Replacement	Gain Deferred	Tax Paid
Exchange 1 (Year 2025)	$800,000 property	$900,000 property	$600,000	$0
Exchange 2 (Year 2030)	$1,200,000 property	$1,500,000 property	$600,000 + $400,000 new = $1,000,000 total	$0
Exchange 3 (Year 2035)	$2,000,000 property	$2,500,000 property	$1,000,000 + $700,000 = $1,700,000 total	$0
Investor dies (Year 2040)	Property worth $3,000,000	Heirs inherit at stepped-up basis	$1,700,000 gain eliminated	$0 (permanently)

Tax avoided through defer-until-death strategy:

Item	Amount
Total deferred gain (3 exchanges)	$1,700,000
Tax that would have been paid (23.8% + depreciation recapture)	~$400,000-$450,000
Tax actually paid	$0
Permanent tax savings	~$400,000-$450,000

Common boot traps:

Boot Type	What Triggers It	Tax Consequence
Cash boot	Receiving cash from the exchange (proceeds not fully reinvested)	Taxable gain to extent of cash received
Mortgage boot	Replacement property has less debt than relinquished property	Debt relief = taxable gain
Unlike property boot	Receiving personal property in the exchange (e.g., equipment, appliances)	FMV of unlike property = taxable gain
Exchange expenses	Paying exchange costs from proceeds (reduces cash reinvested)	May create boot

Example boot calculation:

Item	Relinquished	Replacement
Sale price / Purchase price	$800,000	$750,000
Mortgage	$300,000	$250,000
Equity	$500,000	$500,000

Boot Analysis	Amount
Price shortfall ($800K - $750K)	$50,000 cash boot
Mortgage relief ($300K - $250K)	$50,000 mortgage boot
Total boot	$100,000
Taxable gain (lesser of boot or total gain)	$100,000
Tax on $100,000 (23.8%)	$23,800

To avoid boot: the replacement property must be worth at least as much as the relinquished property, AND the debt must be equal or greater (or the shortfall covered by additional cash).

Properties that don’t qualify:

Property	Why Not
Primary residence	Not held for investment or business (but see IRC 121 exclusion)
Fix-and-flip inventory	Dealer property (held primarily for sale, not investment)
Stock, bonds, securities	Only real property qualifies (post-TCJA)
Partnership interests	Explicitly excluded by IRC 1031(a)(2)(D)
Property outside the US	Can only exchange US for US, or foreign for foreign
Vacation home used personally	Must be primarily investment; personal use must be limited

Reverse exchanges: When the replacement property must be acquired before the relinquished property is sold:

Standard Exchange	Reverse Exchange
Sell first, buy second	Buy first, sell second
QI holds cash	Exchange Accommodation Titleholder (EAT) holds title to replacement
45-day identification, 180-day closing	Same deadlines, but identification is of the property to be sold
Cost: $1,000-$3,000	Cost: $5,000-$15,000+ (EAT fees, holding costs)

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.

If I keep exchanging, how can I use my rental losses?

Not through the exchanges. A chain of 1031 exchanges generally never frees suspended passive losses, because the gain isn’t fully recognized, so the losses keep carrying forward. To use rental losses along the way, you need a route that works in the current year.

Income from profitable rentals or other passive activities absorbs passive losses, since the limit applies only to your net passive loss.
The $25,000 allowance covers some losses if you actively participate and own at least 10%. It’s fully available at modified AGI of $100,000 or less and gone at $150,000.
Real estate professional status needs one person to spend more than half their working hours and more than 750 hours in real property trades or businesses they materially participate in. You then still have to materially participate in the rentals.

If you ever end the chain with a fully taxable sale of your entire interest to an unrelated buyer, whatever’s still suspended from that activity is freed then.
