Section 1031 of the Internal Revenue Code allows a taxpayer to defer capital gains taxes on the sale of investment or business-use real property by reinvesting the proceeds into a "like-kind" replacement property. The tax is not eliminated — it is deferred until the replacement property is eventually sold in a taxable transaction.
For California brokers working with investors, understanding §1031 exchange mechanics is essential. A $1M gain on a California investment property could trigger $380,000 or more in combined federal and California capital gains taxes — the §1031 exchange is the most powerful tool available to defer this liability.

To qualify for full tax deferral:
1. Like-kind property: Both the relinquished (sold) and replacement properties must be held for productive use in a trade or business, or for investment. The "like-kind" standard is broad — an apartment building can exchange for a commercial retail center, which can exchange for raw land. - NOT eligible: Primary residences, inventory (property held for sale), personal property (after TCJA 2017 — real property only)
2. Same taxpayer: The same entity/individual who sells must be the buyer on the replacement side. An individual cannot sell and have their LLC buy.
3. Timeline — 45/180 Rule: - 45-day identification deadline: From close of the relinquished property, the taxpayer has 45 calendar days to identify potential replacement properties in writing to the Qualified Intermediary - 180-day acquisition deadline: The replacement property must close within 180 calendar days of the relinquished property closing - Both deadlines are strict — no extensions except in federally declared disasters
4. Equal or greater value: To defer ALL gain, the replacement property must be of equal or greater value than the relinquished property AND all equity must be reinvested (no "boot" received)
5. Qualified Intermediary (QI): The exchanger CANNOT receive the proceeds from the sale. A QI (also called an accommodator or facilitator) must hold the funds between the close of the relinquished property and the acquisition of the replacement property. If the taxpayer touches the money, the exchange fails.

Boot is any non-like-kind property received in an exchange — cash, debt reduction, or personal property. Boot is taxable.
Types of boot:
An exchange with boot results in partial deferral — the taxpayer pays tax on the boot but defers the remaining gain.
---
When identifying replacement properties within the 45-day window:
Most exchangers use the 3-property rule for simplicity.
---
Reverse exchange: Replacement property is acquired BEFORE the relinquished property is sold. Requires an Exchange Accommodation Titleholder (EAT) to hold title temporarily. Limited to 180 days.
Build-to-suit (improvement) exchange: Exchange proceeds are used to construct improvements on replacement property. The QI holds funds and pays contractors; title is held by a QI entity during construction.
---
California clawback: If a taxpayer does a §1031 exchange out of California (relinquished property in CA, replacement in another state), California retains the right to tax the deferred gain when the replacement property is eventually sold. Taxpayers must file a California form each year tracking the deferred gain.
Depreciation recapture (§1250): Gains attributable to depreciation previously claimed on the exchanged property are taxed as ordinary income (25% max federal rate) in addition to capital gains on appreciation. §1031 defers the capital gain portion; depreciation recapture treatment is more complex.

Quiz Questions:
Q1. An investor sells a San Francisco apartment building for $3M (basis = $1M, gain = $2M). She wants to do a §1031 exchange into a retail strip center in Nevada. What are her deadlines?
A) 30 days to identify, 90 days to close B) 45 days to identify replacement properties, 180 days to close on the replacement property C) 60 days to identify, 180 days to close D) 45 days to identify, 1 year to close
Answer: B — The §1031 exchange mandates exactly 45 calendar days to identify and 180 calendar days to close. These deadlines run from close of the relinquished property (the SF apartment building) and are absolute with no extensions except for federally declared disasters.

Q2. An investor does a §1031 exchange: sells an industrial building for $2M, buys a replacement for $1.8M. The replacement has $400,000 less debt. What is the tax consequence?
A) Full deferral — the replacement property was within 10% of the sale price B) Partial deferral — the $200,000 in unreinvested cash and the $400,000 debt reduction (mortgage boot) are both taxable C) No deferral — the replacement was less than the sale price; the entire gain is taxable D) Full deferral — debt reduction is not treated as boot
Answer: B — The $200,000 cash not reinvested is cash boot. The $400,000 reduction in mortgage (debt relief) is mortgage boot. Both are taxable. To fully defer the gain, the investor would need to reinvest all equity AND acquire a replacement with equal or greater debt.

Q3. An investor's Qualified Intermediary fails to hold the proceeds and deposits them into the investor's personal bank account for convenience while identifying replacement properties. What is the consequence?
A) The exchange is valid as long as the investor re-deposits the funds within 45 days B) The exchange fails — because the investor received (constructively or actually) the proceeds, the sale is a taxable event C) The exchange is valid as long as the investor identifies a replacement within 30 days D) The QI's error is the QI's liability; the investor is protected
Answer: B — The cornerstone of a §1031 exchange is that the exchanger cannot have actual or constructive receipt of the proceeds. If the money is deposited into the investor's account — even temporarily — the exchange fails and the entire gain becomes immediately taxable. The investor may have a malpractice claim against the QI, but the tax liability is the investor's.

Q4. A California investor does a §1031 exchange from a Sacramento rental home into an Arizona vacation resort property (held as investment). California's "clawback" provision means:
A) California taxes the gain immediately when the exchange is completed because the replacement property is outside California B) California defers the tax but requires the investor to file a California form annually tracking the deferred gain; when the Arizona property is sold, California will assess tax on the portion of gain originally deferred C) California has no right to tax gains on property sold outside the state D) The exchange fails because California does not recognize §1031 exchanges for out-of-state replacement properties
Answer: B — California follows federal §1031 deferral but retains the right to tax the deferred gain attributable to the California property. The investor must file CA Form 3840 annually while holding the out-of-state replacement. When the Arizona property is sold, California will assess its portion of the gain that was deferred from the California sale.

Q5. An investor identifies 5 replacement properties within 45 days of closing her relinquished property. The total FMV of the 5 identified properties is $8M; the relinquished property sold for $3M. Does this identification comply with §1031 rules?
A) Yes — there is no limit on the number of properties that can be identified B) No — identification of more than 3 properties triggers the 200% rule; total FMV ($8M) exceeds 200% of relinquished ($6M), so the identification is invalid unless the 95% rule is met C) Yes — the 5-property rule allows identification of up to 5 properties D) No — the maximum identification is 3 properties under all circumstances
Answer: B — When identifying more than 3 properties, the 200% rule applies: the total FMV of identified properties cannot exceed 200% of the relinquished property's FMV ($3M × 2 = $6M). With $8M identified, the 200% rule is violated. The investor can still comply if they acquire 95% of the identified properties' value — the 95% exception. Otherwise, the exchange may be at risk.
