180 Calendar Days

Exchange Completion Deadline

These are strict calendar days. Weekends and federal holidays are not excluded. Missing either deadline disqualifies the exchange.

Understanding the Timeline

The 45-Day
Identification Period

Upon closing on the sale of your relinquished property, the IRS requires you to formally identify potential replacement properties within exactly 45 calendar days. This identification must be made in writing and delivered to a Qualified Intermediary (QI) — a neutral third party who holds the exchange proceeds.

The identification must be unambiguous, describing each property by its legal address, distinguishable name, or other clear designator. Verbal identifications do not qualify. The 45-day clock begins the day after closing and cannot be extended under most circumstances.

The 180-Day
Exchange Period

The complete exchange — meaning the closing on your replacement property — must occur within 180 calendar days of the sale of your relinquished property, or by the due date of your federal tax return for the year of the sale, whichever comes first.

If your tax return is due before the 180-day window closes, you may file for an extension to preserve the full period. The Qualified Intermediary must transfer the identified replacement property to you before this deadline expires or the exchange will be disqualified and full capital gains taxes will apply.

Next Step

Secure your tax deferral with a vetted Qualified Intermediary.

Working with the right QI is the single most important step in a compliant exchange.
