The 1031 like-kind exchange is the most powerful deferral tool in the entire tax code. It allows real estate investors to sell property and reinvest the proceeds into other real estate without paying capital gains tax on the sale. This deferral can continue indefinitely — through multiple exchanges over decades — and ultimately can be eliminated entirely through step-up at death. For long-term real estate investors, 1031 exchanges are the difference between paying taxes once at death (or never) versus paying 25-37% on every transaction.

This lesson covers 1031 exchange fundamentals: how they work, the rules, the deadlines, and how to execute one successfully.

What is a 1031 exchange

A 1031 exchange (named for Section 1031 of the Internal Revenue Code) allows real estate investors to defer capital gains tax when selling investment or business real estate by reinvesting the proceeds into other "like-kind" real estate.

The basic mechanism:

Sell an investment property
Identify replacement property within 45 days
Acquire replacement property within 180 days
Use a Qualified Intermediary to handle the funds
No tax on the sale (deferred to future)

Done correctly, this defers all federal capital gains tax, depreciation recapture, and most state taxes. Done incorrectly, it can be a disaster.

Why it's so powerful

The benefits are enormous:

Tax deferral

A typical sale might generate:

Capital gains: 15-20% federal
Depreciation recapture: 25% federal
NIIT: 3.8%
State: 0-13%
Total tax: 25-50% of total gain

For a $1M gain, that's $250K-$500K of tax. A 1031 exchange defers all of it.

Capital preservation

By deferring tax, you have more capital to reinvest:

Without 1031: $1M sale → $750K after tax → $750K to reinvest
With 1031: $1M sale → $1M to reinvest

That's 33% more capital working for you in the next deal.

Compounding effect

Over multiple exchanges, the difference compounds dramatically:

Starting: $1M
5 exchanges over 25 years at 10% IRR each
With 1031: ~$10M
Without 1031 (paying tax each time): ~$5M

The tax-deferred portfolio doubles the after-tax wealth.

Step-up at death finishes the job

If you hold the final property until death:

All accumulated gain disappears
All depreciation recapture disappears
Heirs receive stepped-up basis
Total tax paid: Zero

This is the "swap until you drop" strategy that has built generational wealth for real estate investors.

The basic requirements

For a 1031 exchange to qualify:

1. Property type

Both properties must be held for investment or business use
Personal residences don't qualify
Vacation homes generally don't qualify
Inventory (developer's land for sale) doesn't qualify

2. Like-kind requirement

This is broader than it sounds. Any real estate held for investment or business is "like-kind" to any other real estate held for investment or business:

Office for retail: Like-kind
Apartment for warehouse: Like-kind
Land for building: Like-kind
Building for land: Like-kind
Single property for multiple properties: Like-kind

The only requirement is that both are real estate. Personal property (equipment, vehicles) does not qualify since 2018 (TCJA changes).

3. Equal or greater value

To fully defer all gain:

Replacement property must equal or exceed sale price (not basis)
Replacement debt must equal or exceed sold debt
All proceeds must be reinvested

If you trade down, you have "boot" — taxable to the extent of the trade-down.

4. Qualified Intermediary required

You cannot touch the proceeds:

Sale proceeds must go to a Qualified Intermediary (QI)
QI holds funds during exchange period
QI uses funds to acquire replacement property
You never receive the cash

Touching the cash kills the exchange.

5. Strict deadlines

45 days to identify replacement property after sale
180 days to close on replacement property after sale
Both deadlines are strict and unmovable

Miss a deadline by one day and the exchange fails.

The 45-day identification rule

Within 45 days of selling the relinquished property, you must identify potential replacement properties.

Identification rules

You can identify properties in one of three ways:

Three Property Rule:

Up to 3 properties of any value
Most common for individual investors
Simplest approach

200% Rule:

Any number of properties
Total value cannot exceed 200% of sold property
Used when considering many alternatives

95% Rule:

Any number of properties
Must acquire 95% of identified value
Rarely used in practice

Identification format

Identification must be:

In writing
Signed
Delivered to the QI or other party
Specifically describe each property
Include addresses or legal descriptions
Within 45 days of sale closing

Email to the QI is acceptable.

Strategic identification

Most investors identify three properties as backup:

Primary target
Backup option 1
Backup option 2

This protects against deals falling through.

Common identification mistakes

Missing deadline (catastrophic)
Vague descriptions (insufficient identification)
Improper format (verbal, unsigned)
Not delivered to QI
Identifying property already under contract (dual identification issues)

The 180-day closing rule

Within 180 days of selling the relinquished property, you must close on the replacement property.

Strict deadline

180 days is exact, not approximate
No extensions for weekends or holidays
No extensions for natural disasters (in normal cases)
Limited extensions for federally declared disasters in some cases

Coordination with tax filing

The 180-day period or the tax return due date (whichever is earlier) is the actual deadline. So if you sell in November, you might need to close before April 15 (or extend your tax return).

Practical implications

Start planning before the sale closes
Have replacement property identified before sale if possible
Budget for delays in closing
Use experienced QI who can move quickly

Common closing mistakes

Underestimating time needed
Closing delays that miss deadline
Title issues that delay
Lender delays for replacement property
Inspection issues that require renegotiation

The Qualified Intermediary

A Qualified Intermediary (QI) is the professional who handles the exchange.

QI requirements

Independent third party
Cannot be the taxpayer's attorney, CPA, or related party
Must have specific exchange documents
Holds funds in segregated accounts
Coordinates the closings

What the QI does

Documents the exchange with appropriate agreements
Receives sale proceeds from sold property
Holds funds during exchange period
Disburses funds to acquire replacement property
Provides identification documentation
Issues final report

Selecting a QI

Look for:

Bonded and insured
Experienced (1031 specialty)
Strong reputation
Segregated accounts for funds
Reasonable fees ($800-$2,500 typical)
Available to your timeline
Clear documentation practices

Risk of using wrong QI

QI failures have happened:

QI bankruptcies (LandAmerica 1031 in 2008)
QI fraud (rare but devastating)
Lost funds
Failed exchanges

Use established, well-capitalized QIs only.

Boot — what makes you taxable

"Boot" is anything received in an exchange that isn't like-kind property. Boot is taxable.

Types of boot

Cash boot:

Cash received by the taxpayer
Cash from refinance before sale
Cash from reduced debt on replacement property

Mortgage boot:

Reduction in debt from sale to replacement
Treated as cash received
Even though no cash changes hands

Other boot:

Non-like-kind property received
Personal property

Examples

Example 1: Sell for $1M with $500K mortgage. Buy for $1M with $500K mortgage. No boot. Full deferral.

Example 2: Sell for $1M with $500K mortgage. Buy for $900K with $400K mortgage.

Cash retained: $100K (price difference)
Debt reduced: $100K (mortgage difference)
Total boot: $200K
Taxable: Up to $200K of gain recognized

Example 3: Sell for $1M (no mortgage). Buy for $1.2M (with $200K mortgage).

No boot if all $1M is reinvested
Full deferral

Avoiding boot

To fully defer gain:

Replacement value ≥ sold value
Replacement debt ≥ sold debt
Reinvest all proceeds
Don't take cash out

Strategic boot

Sometimes investors intentionally take some boot:

Need cash for personal reasons
Partial deferral is better than no deferral
Tax on boot but defer the rest

Reverse exchanges

Sometimes you find the replacement property before you sell the relinquished property. A "reverse exchange" lets you acquire the replacement first.

How it works

Find replacement property
QI buys replacement (parks it temporarily)
You sell relinquished property
QI transfers replacement to you
All within 180 days

Pros

Lock in replacement before selling
No risk of identification deadlines
Good market to sell into

Cons

More complex
More expensive ($5K-$15K extra QI fees)
Need cash or financing to fund the parked property
Requires experienced QI

When to use

Hot market where replacement properties move fast
Specific replacement you must have
Concerns about finding replacement in 45 days

Improvement (build-to-suit) exchanges

You can use exchange proceeds to make improvements to the replacement property.

How it works

Sell relinquished property
QI takes title to replacement
Improvements made during 180-day period
QI transfers improved property to you
Improvements counted in replacement value

Use cases

Vacant land + improvements
Property needing renovation
New construction as part of exchange

Limitations

180-day window is the constraint
Improvements must be completed in time
More complex structure
Higher QI fees

Exchanges with related parties have special rules:

Both parties must hold the exchanged properties for 2 years
Limited exceptions for death, casualty
Different rules for sales and purchases

Generally avoid related party exchanges unless absolutely necessary.

Multi-asset exchanges

You can exchange:

One property for multiple properties
Multiple properties for one property
Multiple properties for multiple properties

The rules are the same. Just more complex coordination.

State considerations

State tax treatment of 1031 exchanges varies:

States that follow federal

Most states (including Florida, which has no income tax) follow federal 1031 treatment. No state tax on the exchange.

States with non-conformity

California: Requires "clawback" — tax owed if you ever sell out-of-state replacement
Pennsylvania: Doesn't recognize 1031 (taxes the gain)
Some others: Various non-conformity issues

For Florida residents and Florida property, this is generally not an issue.

Costs of a 1031 exchange

A typical exchange costs:

QI fees: $800-$2,500
Additional escrow: $200-$500
Title insurance: Same as any deal
Legal review: $1,000-$3,000 (optional)

For larger or more complex exchanges, costs scale up. But compared to the tax savings (often $100K-$1M+), the costs are minimal.

Recent and pending changes

The 1031 rules have been targets for tax reform:

TCJA (2017)

Limited 1031 to real estate only
Removed personal property (equipment, art, etc.)
Real estate exchanges still fully available

Proposed changes

Various administrations have proposed:

Limiting 1031 to $500K of gain per year
Eliminating 1031 entirely
Restricting to certain property types

None have passed. 1031 remains a target but is currently fully available for real estate.

Current status

As of 2025, 1031 exchanges for real estate are fully available with the rules described in this lesson.

Worked example: a Lakeland 1031 exchange

You bought a Lakeland retail center 5 years ago for $4M. It's now worth $6M.

Without 1031

Sell for $6M:

Sale price: $6M
Original basis: $4M
Depreciation taken: $500K
Adjusted basis: $3.5M
Total gain: $2.5M
Section 1250 recapture (25%): $500K × 25% = $125K
Section 1231 capital gain (20%): $2M × 20% = $400K
NIIT: $2.5M × 3.8% = $95K
Florida state tax: $0
Total federal tax: $620K
Net to invest: $5.38M

With 1031

Sell for $6M and exchange into another property:

Sale price: $6M
Tax due: $0 (deferred)
Net to invest: $6M
Replacement property: $7.5M property with new debt
Required equity: ~$2.5M (you have $6M from exchange + new debt)
Excess capital: Available for second property or held in reserve

The compounding benefit

If you do this every 5 years for 25 years (5 exchanges), and each property appreciates by 50% during the hold:

Starting: $4M property
Ending: ~$30M property (with leverage)
Total tax paid: $0
At death: Stepped-up basis eliminates all accumulated tax

Practical considerations

Engage QI before sale closes
Identify replacement properties early
45-day deadline strictly enforced
180-day deadline strictly enforced
Boot avoidance: Replacement value ≥ sold value, replacement debt ≥ sold debt

Common 1031 mistakes

Touching the cash (kills the exchange)
Missing 45-day identification deadline
Missing 180-day closing deadline
No QI engagement before sale
Trading down in value (creates boot)
Reducing debt on replacement (creates boot)
Identifying insufficient or vague replacement property
Wrong QI (uninsured, inexperienced)
Personal use property (not investment)
Related party issues

What to take away

1031 exchange defers all capital gains tax on real estate sales
Like-kind requirement: any real estate for any other real estate
Must use Qualified Intermediary to hold funds
45 days to identify replacement property
180 days to close on replacement property
Replacement value and debt must equal or exceed relinquished
Boot (cash, reduced debt) is taxable to extent of gain
Reverse and improvement exchanges available for special situations
Related party exchanges have restrictions
Florida fully conforms — no state tax issues
Costs of $800-$2,500 vs hundreds of thousands in deferred tax
Step-up at death eliminates all accumulated tax
Common mistakes: touching cash, missing deadlines, trading down, wrong QI
