Part III · Structures · No. 07

Like-kind exchanges

§1031 permits deferral of gain on the exchange of real property held for productive use or investment. Since the 2017 amendment limited the section to real property, like-kind exchange has become the principal — and one of the few remaining — mechanisms for indefinite deferral of appreciation on a luxury asset class.

What the structure is

§1031 of the Internal Revenue Code permits a taxpayer to exchange real property held for productive use in a trade or business or for investment for like-kind real property, with gain deferred. Basis carries over from the relinquished property to the replacement property, preserving the gain for future recognition. The taxpayer who continues to roll real estate through successive §1031 exchanges defers recognition indefinitely; on death, the heirs receive a §1014 step-up that extinguishes the deferred gain.

The tax problem it addresses

Sale of appreciated real property triggers long-term capital gain at 20% plus 3.8% NIIT plus state — combined rates above 30% in high-tax jurisdictions, plus depreciation recapture on improvements. §1031 defers all of it. The taxpayer trades the immediate liquidity of a sale for the preservation of basis and the option to roll into property with greater income or capital-appreciation potential.

Mechanics

• Like-kind. Real property exchanged for real property satisfies the like-kind requirement broadly: an apartment building can be exchanged for raw land, a Manhattan office tower for a Texas ranch.
• Held for productive use or investment. Personal-residence property does not qualify (the §121 exclusion is a different mechanism).
• 45-day identification. Replacement property must be identified within 45 days of the relinquished-property closing.
• 180-day closing. Replacement property must close within 180 days of relinquished-property closing.
• Qualified intermediary (QI). A QI holds the sale proceeds; the taxpayer cannot receive funds directly without breaking the exchange.
• Boot. Cash or non-like-kind property received in the exchange is taxable to the extent of gain realized.

The applicable statutes and authorities

• 26 U.S.C. §1031 (as amended by Pub. L. 115-97, the Tax Cuts and Jobs Act of 2017).
• Treas. Reg. §1.1031(a)-1, -2, -3 (definitions).
• Treas. Reg. §1.1031(k)-1 (deferred exchanges and timing rules).
• Rev. Proc. 2000-37 (reverse exchanges, safe harbor).
• Rev. Proc. 2002-22 (tenant-in-common interests as exchange property).

Substance and audit risk

Recurring audit issues:

• Held-for-investment intent on personal-use property. A vacation home converted to rental shortly before exchange is scrutinized; safe harbors (Rev. Proc. 2008-16) define minimum rental and personal-use limits.
• Identification deadline failure. The 45-day identification rule is strict; failures collapse the exchange.
• Constructive receipt through QI. Sale proceeds passing through the taxpayer (even briefly) destroys the exchange.
• Related-party exchanges. §1031(f) imposes a two-year holding requirement on related-party exchanges; early disposition causes recognition.
• Reverse and improvement exchanges. Safe-harbor compliance under Rev. Proc. 2000-37 requires precise structuring.

Cost and complexity

Qualified-intermediary fees are modest ($1,500 to $5,000 for a typical exchange). Legal and accounting cost is meaningful for non-standard structures (reverse exchanges, multi-property exchanges, build-to-suit exchanges). Most well-documented standard forward exchanges proceed routinely.

Common combinations

• Serial §1031 exchanges into death. Indefinite deferral followed by §1014 step-up — the most tax-favored real-property holding pattern.
• §1031 into Delaware Statutory Trust (DST). Tenant-in-common-like interest in larger institutional property; satisfies §1031 under Rev. Proc. 2002-22 framework.
• §1031 combined with cost-segregation. Replacement property cost-segregated to maximize current depreciation alongside deferred gain.
• Reverse exchange under Rev. Proc. 2000-37. Replacement closes before relinquished; structured through an exchange accommodation titleholder.

Recent developments

The 2017 amendment limiting §1031 to real property remains the principal recent change. Personal-property exchanges — historically used for art, aircraft, vintage cars, and other tangible personalty — are no longer available.

Periodic legislative proposals (including the Biden administration's FY 2022 Greenbook and various follow-on proposals) would cap §1031 deferral or eliminate it for high-income taxpayers; none has been enacted as of the review date.

The Delaware Statutory Trust market has expanded materially since 2010 and remains the principal institutional-grade replacement-property option.
