1031 Like-Kind Exchange: Deadlines, Boot, and QI Rules

A Section 1031 like-kind exchange lets you defer capital gains tax when you sell investment or business real estate, but only if you follow the rules in Internal Revenue Code Section 1031 and Treasury Regulation 1.1031 exactly. The core rules for a 1031 like-kind exchange: both properties must be real estate held for business or investment, a qualified intermediary must hold the sale proceeds, you must identify replacement property in writing within 45 days of closing, you must close on that replacement within 180 days, and you must acquire property of equal or greater value and equity to avoid recognizing taxable gain. Miss any one of these and the IRS treats the transaction as an ordinary sale, with the full gain due in the year you closed.¹

What Property Qualifies

Both the relinquished property and the replacement property must be held for use in a trade or business or for investment. A personal residence does not qualify. Neither does inventory or property you bought planning to flip.¹

Since the Tax Cuts and Jobs Act took effect in 2018, Section 1031 applies only to real property. Equipment, vehicles, artwork, and other personal property no longer qualify, even though they did under prior law.² The statute also excludes stocks, bonds, notes, partnership interests, and certificates of trust.³

The partnership interest exclusion catches many investors off guard. If you hold your property through a partnership or a multi-member LLC taxed as a partnership, you cannot exchange your ownership interest in that entity for a different property. The exchange has to involve the real estate itself, not the entity that owns it. Some investors work around this by converting to tenancy-in-common ownership well in advance of the sale.

Like-Kind Is Broad for Real Estate

For real property, “like-kind” refers to the nature of the asset, not its quality or specific use. Raw land is like-kind to a commercial office building. A strip mall is like-kind to an apartment complex. Improved property is like-kind to unimproved property.⁴ A long-term leasehold interest of 30 years or more, including renewal options, also qualifies as like-kind to a fee simple interest.

One hard boundary: real property in the United States is not like-kind to real property outside the United States. You cannot sell a rental in Arizona and defer the gain into a beachfront condo in Mexico.¹

Vacation Homes and Investment Intent

The IRS cares about why you hold the property. There is no statutory minimum holding period, and the widely cited “two-year rule” is practitioner caution rather than a legal requirement. What matters is whether your actions show genuine investment intent: leasing the property, holding it for appreciation, or using it in a business.

A part-time vacation rental can qualify, but only if the rental activity is real. Revenue Procedure 2008-16 provides a safe harbor. The dwelling must be owned for at least 24 months before the exchange, rented at fair market value for at least 14 days in each of the two 12-month periods before the exchange, and your personal use cannot exceed the greater of 14 days or 10 percent of the days rented in each period.⁵ The same rental and personal-use limits apply to the replacement property for the two years after the exchange.

The Qualified Intermediary Rule

Almost no exchange happens as a simultaneous swap. You sell first, buy later, and that gap is where most exchanges break. If you touch the sale proceeds at any point, the IRS treats the deal as a taxable sale followed by a separate purchase, and the deferral is gone.

A Qualified Intermediary sits in the middle. Before you close on the relinquished property, you sign an exchange agreement that assigns the sale contract to the QI. The buyer’s payment goes directly to the QI, who holds the funds until you identify and close on replacement property. You never have possession of or access to the money.

Who Cannot Serve as Your QI

The QI must be genuinely independent. The regulations disqualify anyone who has been your agent within the previous two years, including your attorney, accountant, real estate broker, or investment banker, along with employees of any of those people.⁶ An attorney or accountant whose only work for you has been on this exchange is not disqualified, but anyone who has handled other matters for you in the past two years is off limits.

The Constructive Receipt Safe Harbors

Even with a QI in place, the IRS can argue you had “constructive receipt” of the money if the exchange agreement lets you demand the cash at will. The regulations provide four safe harbors:

Qualified intermediary holding the funds under an exchange agreement that restricts your right to receive them until the exchange is complete or the deadlines expire.
Qualified escrow account or trust with equivalent restrictions on your access.
Security arrangements where the obligation to deliver replacement property is secured by a mortgage, standby letter of credit, or third-party guarantee rather than cash.
Interest and growth factors, which do not trigger constructive receipt as long as the agreement limits your ability to receive that interest before the deadlines expire.

The QI safe harbor is the one most exchanges use, and the exchange agreement language is what makes or breaks it. The agreement must explicitly state that you cannot demand the funds unless the exchange fails, the identification period expires without a valid identification, or the exchange period runs out.⁶

Where Your Money Actually Sits

The regulations don’t solve a practical risk: your funds are only as safe as your QI. There is no federal bonding or insurance requirement for intermediaries. In 2008, LandAmerica 1031 Exchange Services filed for bankruptcy while holding roughly $420 million belonging to about 450 clients in mid-exchange, and a bankruptcy court ruled the funds were not held in trust because the company had commingled client money with its own operating accounts. Ask how the QI holds funds before signing. Segregated, FDIC-insured accounts are safer than commingled ones. Some states now require QIs to maintain fidelity bonds or segregate funds by law.

The 45-Day and 180-Day Deadlines

Missing a deadline is the most common way exchanges fail. Two clocks start on the day you close on the relinquished property, and neither one stops for any reason.⁶

Identifying Replacement Property Within 45 Days

You have exactly 45 calendar days after transferring the relinquished property to identify potential replacement properties in writing. The identification must be signed by you and delivered to the QI or the seller of the replacement property. A vague description will not work; you need a street address or legal description specific enough that someone could locate the exact property.³

You can revoke an identification and substitute a different property, but the written revocation has to reach the QI before midnight on day 45. After that, your list is locked. Three methods govern how many properties you can identify:

The 3-property rule: identify up to three replacement properties regardless of their value. Their combined value can exceed the value of the relinquished property by any amount, and you only need to close on one to complete the exchange. This is the most commonly used method.
The 200-percent rule: identify more than three properties as long as their combined fair market value does not exceed 200 percent of the fair market value of the relinquished property, measured on the transfer date.
The 95-percent rule: if you identify more than three properties and blow past the 200-percent cap, you are treated as having identified nothing unless you actually acquire properties whose combined value equals at least 95 percent of everything on your list. In practice, this means closing on almost the entire list, and nobody relies on it intentionally.

⁶

Closing Within 180 Days

The second deadline gives you 180 calendar days from the transfer of the relinquished property to close on the replacement. The 180-day period runs alongside the 45-day identification period, not after it, so you really have 135 days from the identification deadline to close.

There is an important wrinkle. The exchange period ends on the earlier of day 180 or the due date of your federal tax return, including extensions, for the year you sold the relinquished property.¹ If you sold in October and your return is due April 15, that is less than 180 days. In that situation, file an extension to preserve the full 180-day window. Investors who forget the extension sometimes lose weeks of exchange time without realizing it.

Neither deadline extends when the final day falls on a weekend or federal holiday. Escrow delays, title problems, and financing holdups do not earn you extra time. The only recognized exceptions have been narrow federal disaster declarations where the IRS has occasionally postponed deadlines for affected taxpayers.

Equal or Greater Value: Boot and Partial Gain

A fully tax-deferred exchange requires you to acquire replacement property of equal or greater value and equity compared to what you sold. When you receive anything that is not like-kind real property, including cash, debt relief, or personal property, the IRS calls it “boot.” You recognize taxable gain up to the amount of the net boot you receive.

Cash Boot and Mortgage Boot

Cash boot is straightforward: if the QI writes you a check for leftover exchange funds after closing, that amount is taxable. Mortgage boot is less obvious but equally dangerous. If you owed $400,000 on the relinquished property and take on only $300,000 in debt on the replacement, the $100,000 of debt relief is mortgage boot. You also receive boot when non-qualifying items like furniture or equipment are bundled into a commercial sale.

The Netting Rules Are Not Symmetrical

You can offset some categories of boot against others, but not in every direction. Debt relief can be offset by either taking on new debt on the replacement property or by paying additional cash into the purchase. So if you were relieved of $100,000 in old debt but put $100,000 of your own cash into the replacement, no mortgage boot is recognized.

Cash boot received works only one way. It can be offset by paying cash, not by taking on more debt. You cannot wipe out a cash distribution by simply putting a bigger mortgage on the replacement property. Equity you extract from the transaction is taxable; equity you add is not.

The Cap on Recognized Gain

Regardless of how much boot you receive, recognized gain can never exceed your total realized gain on the sale. Sell a property with a $300,000 realized gain and receive $50,000 in net boot, and you recognize $50,000, with the remaining $250,000 deferred. Sell with only $30,000 of realized gain but receive $50,000 in net boot, and you recognize $30,000.

Related Party Exchanges

Exchanging with a family member, a business you control, or another related party brings extra scrutiny. Under Section 1031(f), if either you or the related party disposes of the property received in the exchange within two years, the deferred gain becomes taxable in the year of that disposition.¹

“Related person” is broad. It covers siblings, spouse, ancestors, and lineal descendants, entities you control, and partnerships in which you own more than a 50-percent interest. Three narrow exceptions apply: the two-year rule is set aside if one party dies, if the property is lost in an involuntary conversion like a natural disaster, or if you can show the IRS that tax avoidance was not a principal purpose of either the exchange or the later sale.¹

The statute also blocks transactions structured to sidestep these rules, such as routing an exchange through an intermediary to disguise what is really a direct deal with a related party.⁷

Reverse Exchanges When You Buy First

Sometimes the replacement shows up before the relinquished property has sold. A reverse exchange flips the usual order. Revenue Procedure 2000-37 provides a safe harbor.⁸ An Exchange Accommodation Titleholder takes title to the replacement property and “parks” it until you sell the relinquished property. The EAT must be an unrelated party, and the arrangement is documented as a Qualified Exchange Accommodation Arrangement.

The same 45-day and 180-day deadlines apply, running from the date the EAT acquires the parked property. You have 45 days to identify the relinquished property you plan to sell and 180 days to complete the whole exchange. Reverse exchanges cost significantly more than standard deferred exchanges because parking arrangements involve extra legal work, title transfers, and holding costs.

Reporting and What Happens Later

A completed exchange is not the end of the paperwork. You file IRS Form 8824 with your federal tax return for the year you transferred the relinquished property, even if no gain was recognized. The form asks for the dates both properties were identified and received, descriptions of both, the realized gain, and any recognized gain from boot.⁹

Basis Carries Over

Your basis in the replacement property is not what you paid for it. It carries forward from the relinquished property, reduced by any boot received and increased by any gain you recognized, plus additional cash you paid or new debt you assumed.¹ The gap between your carryover basis and the replacement property’s market value is the deferred gain, which becomes taxable whenever you eventually sell without doing another exchange.

Depreciation Recapture Follows the Property

The exchange defers gain but does not erase prior depreciation deductions. Every dollar of depreciation you claimed on the relinquished property carries forward into the reduced basis of the replacement. When you eventually sell in a taxable transaction, the IRS recaptures that depreciation at a 25-percent federal rate under the Section 1250 rules, separate from and in addition to capital gains tax on any remaining appreciation. Chained exchanges over decades can build up substantial recapture liability.

Holding Period Tacks On

Your holding period for the replacement includes the time you held the relinquished property. Hold the original for five years and you are already well past the one-year long-term threshold on day one of ownership of the replacement.

The Estate Angle

If you hold exchanged property until death, your heirs generally receive a stepped-up basis equal to fair market value at the date of death under IRC Section 1014. The entire deferred gain, including accumulated depreciation recapture, effectively disappears. Serial 1031 exchanges are, for that reason, one of the most powerful long-term wealth-building strategies in the tax code.

State Tax Clawback

All 50 states currently recognize Section 1031 for state income tax purposes. A handful, including California, Oregon, Montana, and Massachusetts, impose clawback provisions. Exchange out of a property in one of those states, then later sell the replacement in a taxable transaction, and the original state may seek to collect the deferred state tax even though you no longer own property there. If your exchange crosses state lines, talk to a tax advisor familiar with the specific state rules before closing.
