The basics

What is a 1031 exchange?

Section 1031 of the Internal Revenue Code lets you sell investment or business real estate and put off paying capital gains tax and depreciation recapture, as long as you reinvest the proceeds in other "like-kind" real estate through a qualified intermediary.

Defer

A deferral, not an exemption. The gain carries over into the new property's basis.

Real estate only

Since 2018, only real property qualifies. Equipment, vehicles and art no longer do.

Investment use

Both properties must be held for investment or business. Your home and flips don't qualify.

Why investors use it

Six reasons to exchange instead of sell

Defer the tax

Capital gains and depreciation recapture are postponed, so the full equity keeps working.

Trade up

Move from smaller properties into a larger one with more income or better appreciation.

Change location

Sell in one market and buy in another, as long as both are U.S. real estate.

Consolidate or diversify

Swap several rentals for one, or one building for several.

Less management

Trade a hands-on rental for net-leased commercial property or a passive DST interest.

Plan for heirs

Keep deferring until death; heirs generally get a step-up in basis and the deferred gain disappears.

Eligibility

What qualifies for a 1031 exchange, and what doesn't

Qualifies
✓  Rental homes and condos
✓  Apartment and commercial buildings
✓  Land held for investment
✓  Office, retail and industrial property
✓  Vacation home rented under IRS safe harbor
✓  DST or tenant-in-common interests
Does not qualify
✕  Your primary residence
✕  Fix-and-flip or dealer inventory
✕  Stocks, bonds or LLC/partnership interests
✕  Foreign property for U.S. property
✕  Personal property (since 2018)

Selling your home? Look at the Section 121 exclusion instead: up to $250,000 of gain ($500,000 for married couples) tax-free if you owned and lived there two of the last five years.

Holding period

How long do you have to own it before you exchange?

⚖️I am not a CPA, tax advisor or attorney. This section is general education sourced from the Internal Revenue Code (Sections 121 and 1031), IRS Revenue Procedures 2005-14 and 2008-16, and U.S. Tax Court decisions, listed in the sources below. Holding-period and conversion questions turn on your specific facts. Confirm your plan with a CPA or tax attorney before you list.
No minimum in the law

Section 1031 only requires the property be “held for productive use in a trade or business or for investment.” Your intent at the time of the exchange is what counts.

Common practice: 1–2 years

Many CPAs and exchange companies suggest holding at least one year, ideally across two tax years, so the property shows up as a rental on two returns.

IRS safe harbor: 24 months

For homes, Rev. Proc. 2008-16 is the only IRS-approved timeline: own 24 months, rent at market rate 14+ days in each 12-month period, and keep personal use to the greater of 14 days or 10% of rental days.

Same rule after the exchange

The safe harbor applies to the replacement property too: rent it on the same terms for 24 months before you use it yourself.

What shows the IRS it's an investment

✓  Rented at market rent to real tenants
✓  Advertised and managed like a rental
✓  Little or no personal or family use
✓  Rental income and depreciation reported on Schedule E
✓  Held long enough to show investment intent
✓  A written record of why you're selling

What the Tax Court has said

Taxpayer lost

Goolsby v. Commissioner

T.C. Memo. 2010-64. Owners moved into the replacement property about two months after the exchange, with little effort to rent it. The exchange was disallowed.

Taxpayer won

Reesink v. Commissioner

T.C. Memo. 2012-118. Owners advertised and showed the replacement property for rent, then moved in about eight months later. The court found genuine investment intent.

Primary or second home

You decide to rent out your home. Does it qualify?

A home becomes eligible only once it truly becomes an investment. Renting it for a few months and then selling is the riskiest version.

Second home → rental

Treat it as a business: rent it at market rate, cut back personal use and follow the 24-month safe harbor before exchanging. A home you mostly use yourself won't qualify, however it's titled.

Safest path: 24 months
Primary home → rental

Once you move out and rent it, it can become investment property. Rev. Proc. 2005-14 lets you combine the home-sale exclusion with a 1031: exclude up to $250,000 ($500,000 married) and defer the rest, including depreciation recapture.

Sell within about 3 years of moving out to keep the exclusion
Rented a few months, then sold

There's no safe date, and a short rental invites an audit. If the IRS decides it was still a personal home, the exchange fails and the gain is taxed.

Risky: talk to your CPA first
Example: home-sale exclusion + 1031 togetherA married couple bought a home for $400,000, lived in it for years, then moved out and rented it. They sell it for $1,300,000 within 3 years of moving out, for a $900,000 gain. Under Rev. Proc. 2005-14 they exclude $500,000 under Section 121, can take up to that amount in cash tax-free, and defer the remaining $400,000 (including depreciation recapture) by buying replacement property worth at least $800,000. Simplified: ignores closing costs and mortgages.

Going the other way: if you move into a property you got through a 1031 exchange, you must own it at least 5 years before you can use the home-sale exclusion, and rental years before you moved in can reduce the exclusion.

The clock

45 days to identify. 180 days to close.

Day 0Sale closes; funds go to the QIDay 45Written identification dueDay 180Purchase must close45 days135 more days · 180 totalThe periods run at the same time and are not extended for weekends or holidays. Day 180 moves earlier if your tax return is due first.
Example

Sale closes March 2. Identification is due April 16. The purchase must close by August 29.

Tax return trap

Sell in December and day 180 lands after April 15. File a tax extension, or the deadline shrinks to your return's due date.

Disasters only

The IRS extends these deadlines only for federally declared disasters (Rev. Proc. 2018-58), never for financing delays.

The rules

Six rules for a fully tax-deferred exchange

Use a qualified intermediary

The sale proceeds must go to a QI, never to you. Touching the money, even briefly, generally kills the exchange.

Identify within 45 days

Name replacement property in writing, signed and delivered to the QI by midnight of day 45. No weekend or holiday extensions.

Close within 180 days

Acquire the replacement by day 180, or by your tax return due date if earlier. File an extension if the return would come due first.

Buy equal or greater value

To defer all tax, the replacement price should be at least the net sale price and you should reinvest all of the net cash.

Replace the debt

If your old mortgage was $500K, the new property needs $500K of new debt, or you add cash to make up the difference.

Same taxpayer on title

The person or entity that sells must be the one that buys. A single-member LLC you own counts as you.

Identification rules: how many properties can you name?

3-property rule

Identify up to three properties of any value. This is what most investors use.

200% rule

Identify more than three, as long as their total value is no more than 200% of what you sold.

95% rule

Identify any number of any value, but you must actually buy at least 95% of the total value identified.

Tip: identify a backup. If your first choice falls through after day 45, you can only buy what's on your list.

Estimate it

Estimates only. Depreciation recapture is taxed at up to 25%; actual tax depends on your full return, state of the property and holding period. Ask your CPA to run your numbers.

Boot

What makes part of an exchange taxable?

"Boot" is anything you receive that isn't like-kind real estate: cash you keep, or debt you shed without replacing. It's taxable up to the amount of your gain.

Exchange types

Six ways to structure a 1031 exchange

Delayed exchange

The standard: sell first, buy within 180 days. The vast majority of exchanges.

Simultaneous exchange

Sale and purchase close the same day. Rare today.

Reverse exchange

Buy the new property first; an accommodator holds title until you sell (Rev. Proc. 2000-37).

Improvement / build-to-suit

Use exchange funds to improve the replacement property before you take title.

DST (Delaware Statutory Trust)

Buy a fractional interest in institutional property; fully passive (Rev. Rul. 2004-86).

Tenant-in-common (TIC)

Co-own a property with other investors as a deeded fractional owner.

Step by step

How a delayed exchange works

  1. Plan before you listTalk to your CPA and a qualified intermediary before signing a sale contract.
  2. Add exchange languageBoth contracts should include a 1031 cooperation clause; the other party signs an assignment to your QI.
  3. Close the saleProceeds wire directly to the QI. Day 0 starts the clock.
  4. Identify by day 45Send your signed written identification to the QI.
  5. Close the purchase by day 180The QI wires funds to the closing; title goes to the same taxpayer.
  6. File Form 8824Report the exchange on your tax return for the year of the sale.
Costs

What a 1031 exchange costs

ItemTypical range
Qualified intermediary, standard delayed exchange$600 – $1,500
Each additional replacement property$250 – $500
Reverse or improvement exchange$3,000 – $10,000+
Normal closing costs on both sidesTitle, doc stamps, recording, lender fees
CPA to prepare Form 8824Varies
Florida: no state income tax

The federal tax is the main concern. Property sold in another state may still be taxed there.

Doc stamps still apply

An exchange defers income tax only. Florida documentary stamp tax and closing costs apply to both deeds.

Foreign sellers

FIRPTA generally requires 15% withholding unless the IRS issues a withholding certificate before closing.

Avoid these

Seven mistakes that break an exchange

  1. Receiving the sale proceeds, even for a day
  2. Missing day 45 or day 180 (only federally declared disasters can extend them)
  3. Buying a lower-priced property or taking less debt without adding cash
  4. Changing who is on title between the sale and the purchase
  5. Buying from a related party who then sells within two years
  6. Using your own agent, attorney or CPA from the last two years as the QI (a disqualified person)
  7. Exchanging a property held primarily for resale (a flip)
The long game

"Swap till you drop"

Each exchange carries the old basis forward, so the deferred gain grows. But when an investor dies, heirs generally receive the property with a step-up in basis to market value, and the deferred gain is usually never taxed.

Plan the ownership tooHolding exchange properties in LLCs owned by a revocable trust keeps the step-up for heirs while avoiding probate. See the Trust Education guide.
FAQ

1031 exchange questions clients ask me

What is a 1031 exchange?

A tax-deferral strategy under Section 1031 of the Internal Revenue Code. When you sell investment or business real estate and reinvest the proceeds in other like-kind real estate through a qualified intermediary, capital gains tax and depreciation recapture are postponed.

What are the 45-day and 180-day rules?

You have 45 days from the sale closing to identify replacement property in writing, and 180 days from the sale (or your tax return due date, if earlier) to close on it. The two periods run at the same time, and weekends and holidays don't extend them.

Can I do a 1031 exchange on my primary residence?

No. A primary residence doesn't qualify. Homeowners may instead exclude up to $250,000 of gain ($500,000 for married couples) under Section 121 if they owned and lived in the home two of the last five years.

Does a vacation home qualify for a 1031 exchange?

It can, under the IRS safe harbor in Rev. Proc. 2008-16: own it at least 24 months, rent it at fair market value for 14 or more days in each of the two years, and limit personal use to the greater of 14 days or 10% of days rented.

How long do I have to own a property before I can do a 1031 exchange?

The tax code sets no minimum holding period. The property must be 'held for productive use in a trade or business or for investment,' which depends on your intent and the facts. Many CPAs and exchange companies suggest at least one year, ideally spanning two tax years, and the only IRS-approved timeline is the 24-month safe harbor for homes in Rev. Proc. 2008-16. The shorter the hold, the more likely the IRS will question it.

If I start renting out my home or second home, how soon can I exchange it?

There's no fixed date, but renting it for only a few months before selling is risky. The IRS and the Tax Court look at whether it truly became an investment: market rent, real tenants, little or no personal use, and rental income and depreciation reported on your return. To be safe, follow the 24-month safe harbor: own it 24 months, rent it at market rent 14+ days in each 12-month period, and limit personal use to the greater of 14 days or 10% of rental days.

Can I use the home-sale exclusion and a 1031 exchange together?

Yes, if the home was your primary residence and then became a rental. Under Rev. Proc. 2005-14 you apply the Section 121 exclusion first (up to $250,000, or $500,000 married, if you lived there 2 of the last 5 years) and then defer the rest of the gain, including depreciation recapture, with a 1031 exchange. Because of the 2-of-5-year rule, you generally need to sell within about 3 years of moving out.

What if I rented my home for only a few months and then sold it through a 1031?

The IRS could disallow the exchange and tax the gain. Courts have gone both ways: in Goolsby (2010) owners who moved into their replacement property about two months after the exchange lost, while in Reesink (2012) owners who moved in after eight months won because they had genuinely tried to rent it first. Facts and documentation decide these cases, so talk to your CPA before you sell.

What is 'like-kind' property?

For real estate, almost any U.S. investment or business real property is like-kind to any other: a condo for land, an apartment building for a warehouse. U.S. and foreign property are not like-kind to each other.

What is boot?

Cash or debt relief you receive that isn't reinvested. Boot is taxable up to the amount of your gain. Buying a cheaper property, keeping some cash, or taking on less debt all create boot.

Do I have to reinvest all the money?

To defer all of the tax, yes. Reinvest all net proceeds and buy property of equal or greater value. You can keep some cash, but that portion is taxable.

What does a qualified intermediary do?

The QI holds your sale proceeds, prepares the exchange documents, receives your identification and wires funds to the purchase. Your own agent, attorney, CPA or employee from the past two years cannot serve as your QI.

How much does a 1031 exchange cost?

Qualified intermediary fees commonly run about $600 to $1,500 for a standard delayed exchange, with more for extra properties and $3,000 to $10,000 or more for reverse or improvement exchanges, plus normal closing costs.

Can I buy the new property before I sell?

Yes, through a reverse exchange. An exchange accommodator takes title to the new property and holds it until you sell the old one, all within 180 days. It costs more and often needs cash or special financing.

Can I move into a property I bought through a 1031 exchange?

Eventually, but carefully. It must first be held for investment. If you later convert it to a residence, you must own it at least five years before you can use the home-sale exclusion, and part of the gain may still be taxable.

Does Florida tax capital gains?

No. Florida has no state income tax, so the federal tax is the main concern. If you sell property in another state, that state may still tax the gain, and some, like California, track the deferred gain.

What happens to the deferred tax when I die?

Your heirs generally receive the property with a step-up in basis to market value, so the deferred gain is usually never taxed. Investors call this 'swap till you drop.'

Can a foreign seller do a 1031 exchange?

Yes, but FIRPTA generally requires 15% of the sale price to be withheld unless the IRS issues a withholding certificate, which should be applied for before closing.

Can I exchange into a DST?

Yes. A Delaware Statutory Trust interest qualifies as real property for 1031 purposes (Rev. Rul. 2004-86). DSTs are passive and are often used as backup identifications, but they are securities with their own fees and risks.

Do doc stamps and closing costs still apply?

Yes. A 1031 exchange defers income tax only. Florida documentary stamp tax, title insurance and other closing costs apply to both the sale and the purchase.

What form do I file?

IRS Form 8824, Like-Kind Exchanges, with your tax return for the year you sold the relinquished property.
