CPA REG: Like-Kind Exchanges Under Section 1031

Master IRC Section 1031 like-kind exchange rules for the CPA REG exam, including qualifying property, boot, basis calculations, and the 45/180-day timelines.

Like-Kind Exchanges: Section 1031 for the REG Exam

Section 1031 allows taxpayers to defer gain on the exchange of like-kind property used in a trade or business or held for investment. After the TCJA, like-kind exchange treatment is limited to real property. Personal property, such as vehicles, equipment, and artwork, no longer qualifies. This provision is one of the most powerful tax deferral tools available and is heavily tested on the REG exam.

Qualifying Property

To qualify for Section 1031, the property exchanged and the property received must both be real property held for productive use in a trade or business or for investment. The properties must be of like kind, which for real property is interpreted broadly. Commercial real estate can be exchanged for residential rental property, improved property for unimproved land, and a fee simple interest for a leasehold of 30 years or more. Property held primarily for sale (such as dealer inventory) does not qualify.

The following do not qualify for like-kind exchange treatment: property held primarily for sale (dealer property), stocks, bonds, or notes, partnership interests, certificates of trust or beneficial interests, and choses in action. Additionally, exchanges of real property located in the United States for real property located outside the United States do not qualify.

Boot and Gain Recognition

Boot is non-like-kind property received in the exchange, including cash, relief of liabilities, and non-qualifying property. Gain is recognized to the extent of boot received. The recognized gain cannot exceed the total realized gain. Losses are never recognized in a like-kind exchange, even if boot is received.

When mortgages are involved, the analysis is critical. Net liability relief (the excess of liabilities transferred over liabilities assumed) is treated as boot received. Cash paid or additional liabilities assumed can offset liability relief. The netting of mortgages is one of the most commonly tested computational aspects of Section 1031 on the REG exam.

Basis of Property Received

The basis of like-kind property received is calculated as the adjusted basis of the property given up, decreased by any money or boot received, increased by any gain recognized, and increased by any boot given. An alternative approach is to start with the fair market value of the property received and subtract any deferred gain (or add any deferred loss). Both methods should yield the same result.

For example, if a taxpayer exchanges property with a $100,000 basis and a $150,000 fair market value plus receives $20,000 cash for like-kind property worth $130,000, the realized gain is $50,000, the recognized gain is $20,000 (limited to boot received), and the basis of the new property is $100,000 ($100,000 basis minus $20,000 boot received plus $20,000 gain recognized).

Deferred (Starker) Exchanges

A simultaneous exchange of properties is rare. Most Section 1031 exchanges are deferred exchanges in which the taxpayer transfers the relinquished property and later receives the replacement property. Deferred exchanges must comply with two strict timelines. The 45-day identification period requires the taxpayer to identify potential replacement properties in writing within 45 days of transferring the relinquished property. The 180-day exchange period requires the taxpayer to receive the replacement property within 180 days of the transfer or by the due date of the tax return (including extensions) for the year of transfer, whichever is earlier.

The taxpayer may identify up to three replacement properties regardless of value (the three-property rule), or any number of properties whose total fair market value does not exceed 200% of the relinquished property's value (the 200% rule). Failure to meet either deadline disqualifies the entire exchange, and the transaction is treated as a taxable sale.

Related Party Rules

Like-kind exchanges between related parties are subject to a two-year holding requirement under IRC Section 1031(f). If either party disposes of the property received within two years, the original exchange is disqualified and any deferred gain is recognized. Exceptions include dispositions due to death, involuntary conversions, and transactions where tax avoidance was not a principal purpose.

Exam Strategy

  • Always verify both properties are qualifying real property held for business or investment use
  • Calculate boot carefully by netting liabilities, cash, and non-like-kind property
  • Remember that gain is recognized to the lesser of the realized gain or boot received
  • Losses are never recognized in a Section 1031 exchange
  • Memorize the 45-day and 180-day deadlines for deferred exchanges
  • Watch for related party scenarios with the two-year holding requirement
