A deferred 1031 exchange has two hard timing checkpoints: identify replacement property within 45 days and receive it within 180 days, or by the earlier due date of the tax return for the year of transfer, including extensions. The qualified intermediary, identification rules, and boot analysis must be arranged before the physician’s relinquished property closes.

1031 exchange timeline at a glance
| Milestone | Deadline or action | Why it matters |
|---|---|---|
| Before closing | Engage the qualified intermediary and review the exchange agreement. | The process should be structured before the taxpayer receives sale proceeds. |
| Transfer of relinquished property | Start the 45-day and 180-day clocks. | The transfer date controls the statutory periods. |
| Identification period | Identify replacement property in writing by day 45. | Late or defective identification can prevent deferred-exchange treatment. |
| Exchange period | Receive replacement property by day 180 or the earlier return due date. | Both the 180-day limit and the return due-date limit matter. |
Day 0: prepare before the sale
Before the relinquished property closes, confirm that the property is held for business or investment, not primarily for sale. Review title, entity ownership, adjusted basis, debt, expected proceeds, depreciation, and transaction costs. Select a qualified intermediary and provide the intermediary with the closing and assignment documents.
A physician should also decide whether the replacement property will be held directly or through an entity. Changing the taxpayer or ownership structure during the exchange can create a mismatch. The CPA, attorney, lender, title company, and intermediary should agree on the transaction flow before closing.
Days 1-45: identify replacement property
The replacement property must be identified in writing within 45 days after the transfer of the relinquished property. A clear legal description, street address, or distinguishable property name can be used under the applicable rules. The identification should be delivered to a permitted party, such as the qualified intermediary, within the deadline.
The identification period is not a time to casually browse. A physician should evaluate financing, inspections, title, projected income, property use, environmental concerns, and ownership before listing a property on the identification notice. The property received must be identified, subject to the permitted identification rules.
The three-property rule
The standard rule allows a taxpayer to identify up to three replacement properties, regardless of their value. The taxpayer can receive one or more of those properties if the other exchange requirements are met. This is often useful when a physician is comparing a medical-office building, a multifamily property, and a passive investment alternative.
The 200% rule
Instead of limiting the list to three properties, the taxpayer may identify any number of properties if the aggregate fair market value of the identified properties does not exceed 200 percent of the aggregate fair market value of all relinquished properties. The value test applies to the identification list, not just the property ultimately purchased.
For example, if the relinquished property is valued at $1,000,000, the total fair market value of identified replacement properties generally cannot exceed $2,000,000 under the 200% rule. A physician should not assume that adding more backup properties is harmless. Have the written identification and valuation reviewed before the day-45 deadline.
The 95% rule
A taxpayer who identifies more property than permitted by the three-property or 200% rule may still satisfy the identification rules under the 95% rule if the taxpayer receives replacement property with a fair market value at least equal to 95 percent of the aggregate fair market value of all identified properties. This is a demanding rule, not a routine fallback. Do not use it as a reason to submit an unmanageable list.
Days 46-180: complete the exchange
The replacement property must be received by the earlier of day 180 after the transfer or the due date of the taxpayer’s federal income tax return for the year of transfer, including extensions. Filing an extension does not extend the statutory 180-day period, but it can affect the alternate return due-date limit when the return due date would otherwise arrive first.
Financing delays, inspections, title problems, lender conditions, and entity documents do not automatically extend the exchange period. Choose a replacement property that can close on time and keep the intermediary informed about every change.
What the qualified intermediary does
A qualified intermediary is an independent party that enters into a written exchange agreement, receives an assignment of the taxpayer’s rights under the sale and purchase contracts, holds the exchange funds, and transfers funds and documents according to the exchange structure. The intermediary helps preserve the mechanics of a deferred exchange, but does not determine the taxpayer’s basis, gain, or California filing obligations.
Related parties and disqualified persons cannot serve as the qualified intermediary under the applicable rules. A physician should review the intermediary’s experience, agreement, fees, safeguards, and procedures for handling funds before signing.
Boot during the exchange
Boot is cash or other non-like-kind property received in the transaction. Cash taken from the exchange, non-real-estate assets, and some net debt relief can create recognized gain up to the amount of boot. The exchange may still defer the remaining gain, but the result is not necessarily full deferral.
Suppose a physician sells an investment property and receives cash back because the replacement property costs less or the new financing is smaller. The CPA should model the consequences before the closing statement is finalized. A larger replacement price alone does not guarantee full deferral if equity is withdrawn or other non-like-kind property is received.
How the timeline article differs from the California rules page
This article focuses on federal process mechanics, deadlines, identification options, qualified-intermediary responsibilities, and boot. The companion 1031 exchange for physicians in California article focuses on property ownership, physician-investor scenarios, cross-state reporting, and California Form FTB 3840. The existing California 1031 exchange rules page remains the broader state-law hub.
Deadline checklist for a physician

- Before closing, model cash, debt, non-like-kind property, basis, and boot.
- After closing, retain the exchange agreement, identification, closing statements, Form 8824 information, and state reporting records.

Frequently asked questions
Is the 45-day period calendar days?
Yes. The identification period runs from the transfer of the relinquished property and ends on the applicable 45th-day deadline. Do not assume weekends, inspections, or lender delays extend it.
Is the 180-day period always available?
The replacement property must be received by the earlier of day 180 or the due date of the taxpayer’s return for the year of transfer, including extensions. The earlier date controls.
Can a CPA be the qualified intermediary?
Not automatically. The intermediary must satisfy the applicable independence and disqualified-person rules. A CPA may provide tax advice while a separate qualified intermediary handles exchange funds and documents.
