22.1 Section 1031 Like-Kind Exchanges (Real Property Only, 45-Day/180-Day Deadlines)

Statutory Framework of IRC §1031 Post-TCJA

Under IRC §1031(a)(1), no gain or loss is recognized on the exchange of real property held for productive use in a trade or business or for investment if such property is exchanged solely for real property of like kind which is to be held either for productive use in a trade or business or for investment.

Historically, Section 1031 applied to tangible personal property, including corporate aircraft, heavy construction machinery, vehicle fleets, and agricultural equipment. However, the Tax Cuts and Jobs Act (TCJA) fundamentally altered the statute by restricting Section 1031 exclusively to real property for transfers completed after December 31, 2017. For Tax Year 2025 and on the Special Enrollment Examination (SEE), any exchange of personal property, intangible property, or financial instruments is treated as a fully taxable sale and purchase.

IRC §1031 Qualifying Scope:
  [YES] Commercial office buildings, warehouses, retail storefronts
  [YES] Multi-family residential rental apartments and residential rental homes
  [YES] Agricultural land, timberland, and unimproved vacant lots held for investment
  [YES] 30-year or longer leasehold interests in real property
  [YES] Oil, gas, and mineral interests classified as real property under state law
  --------------------------------------------------------------------------------
  [NO]  Tangible personal property (machinery, equipment, vehicles, furnishings)
  [NO]  Real property held primarily for sale (dealer inventory, fix-and-flip properties)
  [NO]  Personal-use property (taxpayer's primary residence, personal vacation home)
  [NO]  Partnership interests, LLC membership interests, corporate stocks, bonds, notes
  [NO]  Domestic real property exchanged for foreign real property (§1031(h))

Statutorily Excluded Real Property

Even within the realm of real estate, specific property classes are statutorily barred from Section 1031 nonrecognition under IRC §1031(a)(2):

1. Property Held Primarily for Sale (Dealer Inventory): Real estate developers, builders, and fix-and-flip investors who acquire land or buildings with the primary intent of reselling to customers in the ordinary course of business cannot utilize §1031. An investor must demonstrate an intent to hold the property for long-term productive business use or rental income.
2. Personal-Use Property: A taxpayer's principal residence (governed by IRC §121) or personal vacation home is disqualified. However, under Rev. Proc. 2008-16, the IRS provides a safe harbor allowing a dwelling unit to qualify for §1031 if, in each of the two 12-month periods immediately before and after the exchange: (a) the unit is rented to an unrelated person at fair rental value for at least 14 days, and (b) the taxpayer's personal use does not exceed the greater of 14 days or 10% of the days rented.
3. Partnership & Multi-Member LLC Interests (§1031(a)(2)(D)): A partner cannot exchange an interest in a partnership for an interest in another partnership, nor can a partner exchange a partnership interest for direct fee-simple real estate. To achieve deferral when individual partners desire different outcomes, partnerships frequently execute a "drop and swap" (liquidating partnership interests into direct tenancy-in-common (TIC) interests under Rev. Proc. 2002-22) prior to the exchange.

The Broad "Like-Kind" Standard for Real Estate

Under Treas. Reg. §1.1031(a)-1(b), the phrase like-kind refers to the nature or character of the property and not to its grade or quality. One kind or class of property may not be exchanged for property of a different kind or class; however, the fact that any real estate involved is improved or unimproved is not material, because that fact relates only to its grade or quality, not to its nature.

Consequently, the like-kind test for domestic real estate is exceptionally broad. An investor may exchange almost any parcel of business or investment real estate for any other parcel of business or investment real estate:

Deferred (Starker) Exchanges Under IRC §1031(a)(3)

In the real estate market, simultaneous two-party exchanges (where Party A transfers Property X to Party B at the exact instant Party B transfers Property Y to Party A) are extraordinarily rare. The vast majority of transactions are structured as deferred (non-simultaneous) exchanges, authorized under IRC §1031(a)(3) following the landmark Starker v. United States decision.

In a deferred exchange, the taxpayer transfers the relinquished property first and subsequently identifies and acquires one or more replacement properties. To qualify for nonrecognition, the transaction must satisfy two strict, statutory deadlines:

Deferred Exchange Timeline (Both clocks start on Day 0 = Date of Transfer):
  Day 0: Taxpayer transfers Relinquished Property to Qualified Intermediary (QI)
    │
    ├─────────────────────────────► Day 45: Identification Window Closes (Midnight)
    │                               Must identify replacement property in writing.
    │
    └──────────────────────────────────────────────────────────► Day 180: Exchange Window Closes
                                                                 Earlier of 180 calendar days OR
                                                                 tax return due date (+ extensions).

1. The 45-Day Identification Period (§1031(a)(3)(A))

• Deadline: The replacement property must be unambiguously identified in writing on or before midnight of the 45th calendar day following the date the taxpayer transferred the relinquished property.
• Written Notice: The identification must be signed by the taxpayer and hand-delivered, mailed, faxed, or electronically transmitted to a qualified party involved in the exchange (typically the Qualified Intermediary), but never to the taxpayer's own agent.
• Legal Identification Rules: The taxpayer must identify potential replacement properties under one of three exclusive statutory safe harbors:
  1. The 3-Property Rule: The taxpayer may identify up to three (3) replacement properties, regardless of their aggregate fair market value (FMV). The taxpayer may acquire one, two, or all three properties.
  2. The 200% Rule: The taxpayer may identify any number of replacement properties, provided that their aggregate fair market value at the end of the 45-day period does not exceed 200% of the aggregate fair market value of all relinquished properties on the date of transfer.
  3. The 95% Rule: If the taxpayer identifies more than 3 properties and their aggregate FMV exceeds 200% of the relinquished property's FMV, the identification is invalid unless the taxpayer actually acquires identified replacement properties whose aggregate FMV equals at least 95% of the aggregate FMV of all properties identified.

2. The 180-Day Exchange Period (§1031(a)(3)(B))

Under IRC §1031(a)(3)(B), the replacement property must be received by the taxpayer by the earlier of:

1. 180 calendar days after the date on which the taxpayer transferred the relinquished property; OR
2. The due date (including extensions) of the taxpayer's federal income tax return for the taxable year in which the transfer of the relinquished property occurred.

The Tax Return Due Date Trap on the EA Exam

A frequent exam scenario tests a transfer occurring late in the calendar year:

• Scenario: Taxpayer transfers relinquished property on November 1, 2025.
• 180 calendar days from November 1, 2025 is April 30, 2026.
• However, the taxpayer's 2025 Form 1040 is due on April 15, 2026.
• If the taxpayer does not file an extension, the exchange period terminates prematurely on April 15, 2026 (the return due date), cutting the exchange window to only 165 days! Any property acquired between April 16 and April 30 is fully taxable.
• The Remedy: The taxpayer must timely file Form 4868 (automatic 6-month extension to October 15, 2026) before April 15, 2026. This extends the tax return due date, preserving the full 180-day window through April 30, 2026.

The Qualified Intermediary (QI) & Constructive Receipt

Under Treas. Reg. §1.1031(k)-1(g)(4), the taxpayer must avoid actual or constructive receipt of the sales proceeds from the relinquished property. If at any time during the exchange period the taxpayer possesses the unrestricted legal right to receive, pledge, borrow, or control the escrowed funds, the exchange fails immediately, and the full realized gain is taxed.

To preserve tax deferral, the parties engage a Qualified Intermediary (QI):

• The QI enters into a written exchange agreement with the taxpayer.
• The QI takes title to (or assigns contracts for) the relinquished property, transfers it to the ultimate buyer, holds the net sale proceeds in a segregated qualified escrow account, and uses the funds to purchase the replacement property from the seller.
• The "(g)(6) Restrictions": The exchange agreement must expressly provide that the taxpayer has no right to receive, pledge, borrow, or obtain the benefits of the cash or other property held by the QI before the expiration of the 45-day or 180-day period.

Disqualified Persons Under Treas. Reg. §1.1031(k)-1(k)

A person cannot serve as a Qualified Intermediary if they are a disqualified person. A disqualified person is:

1. The taxpayer's employee, attorney, accountant/CPA, investment banker, or real estate broker/agent who has performed professional services for the taxpayer within the two-year period ending on the date of the transfer of the relinquished property (routine routine escrow or closing services do not taint eligibility);
2. Any related person defined under IRC §267(b) or §707(b) (e.g., spouse, siblings, ancestors, lineal descendants, or controlled corporations/partnerships with >50% ownership).

Reverse Exchanges Under Rev. Proc. 2000-37

In a reverse exchange, a taxpayer must acquire the replacement property before transferring the relinquished property (e.g., in a competitive commercial bidding environment). Because a taxpayer cannot exchange property with themselves, the IRS established a safe harbor in Rev. Proc. 2000-37 using an Exchange Accommodation Titleholder (EAT):

• The EAT takes qualified indicia of ownership (parks title) to either the replacement property or the relinquished property under a written Qualified Exchange Accommodation Arrangement (QEAA).
• The taxpayer must identify the relinquished property within 45 days of the EAT taking title.
• The entire transaction must be fully closed within 180 days of the EAT acquiring the parked title.

Comprehensive Worked Numerical Example: Identification & Timeline Coordination

On October 15, 2025, Horizon Logistics Inc. (a calendar-year C corporation) closes the transfer of an industrial terminal (relinquished property) for a fair market value of $2,000,000 through a Qualified Intermediary.

Step 1: Calculate the 45-Day Identification Deadline
  - Transfer Date: October 15, 2025 (Day 0)
  - October has 31 days (16 remaining days in October)
  - November has 30 days (Day 45 falls on November 29, 2025)
  - Identification Deadline: Midnight, November 29, 2025 (Saturday).
  - Rule: Strict calendar days apply! No weekend rollover. Identification must be sent by Nov 29.

Step 2: Evaluate Proposed Identification Lists under Statutory Safe Harbors
  Relinquished Property FMV = \$2,000,000.

  Option A: Horizon identifies 3 commercial properties valued at \$1.5M, \$2.2M, and \$3.1M.
    -> Total identified: 3 properties (Aggregate FMV = \$6,800,000).
    -> Test: Meets the 3-Property Rule! Value is irrelevant when 3 or fewer properties are named.

  Option B: Horizon identifies 5 distribution hubs valued at \$700,000 each (Total FMV = \$3,500,000).
    -> Total identified: 5 properties (> 3 properties, so 3-Property Rule is failed).
    -> Test 200% Rule: 200% x \$2,000,000 = \$4,000,000.
    -> Total FMV (\$3,500,000) <= \$4,000,000. Valid identification under the 200% Rule!

  Option C: Horizon identifies 6 properties valued at \$900,000 each (Total FMV = \$5,400,000).
    -> Total identified: 6 properties (> 3 properties).
    -> Test 200% Rule: \$5,400,000 exceeds \$4,000,000 ceiling. Disqualified under 200% Rule.
    -> Test 95% Rule: Valid ONLY IF Horizon actually acquires at least 95% of \$5,400,000 (\$5,130,000).

Step 3: Calculate the 180-Day Exchange Period Deadline
  - Transfer Date: October 15, 2025.
  - 180 calendar days from October 15, 2025 is April 13, 2026.
  - Corporate Tax Return Due Date (Form 1120): April 15, 2026.
  - The earlier of 180 days (April 13, 2026) or return due date (April 15, 2026) is April 13, 2026.
  - Horizon must close on the replacement property by April 13, 2026.

Disaster postponements

The ordinary 45-day and 180-day periods do not roll forward merely because their last day is a weekend or holiday. Nevertheless, specific federally declared disaster relief can postpone deadlines for affected taxpayers. Apply an announced postponement when the facts qualify; do not interpret the ordinary calendar-day rule as a ban on statutory disaster relief.
