The 45 Day Identification Period

The forty-five day identification period is the first and least forgiving deadline in a Section 1031 exchange. The clock begins on the day the relinquished property closes escrow and title transfers, not on the day the investor decides to exchange. Investors in San Francisco, CA have exactly forty-five calendar days, including weekends and federal holidays, to identify potential replacement property in writing to their qualified intermediary. There is no administrative extension available for a slow escrow, a delayed wire, or the pace of a competitive Bay Area purchase market.

How the Forty-Five Day Clock Actually Runs

Many investors selling property in neighborhoods such as the Mission, SOMA, or the Sunset District assume the search for replacement property can begin after the relinquished sale closes. In practice, waiting until day one to start research puts the investor at a disadvantage, because forty-five days includes time needed for property tours, preliminary underwriting, and coordination with a lender for any replacement financing. We recommend that investors begin building a target list during the marketing period for the relinquished property, well before escrow closes, so that written identification can be delivered to the qualified intermediary early in the window rather than on day forty-four.

Identification must satisfy one of three IRS counting rules. Under the three property rule, an investor may identify up to three properties of any value. Under the two hundred percent rule, an investor may identify more than three properties as long as their combined fair market value does not exceed two hundred percent of the value of the relinquished property. Under the ninety-five percent rule, an investor may identify any number of properties as long as at least ninety-five percent of their combined value is ultimately acquired. Choosing the wrong rule, or identifying property informally by phone or email to a broker instead of in writing to the qualified intermediary, can invalidate the identification and the deferral.

What Counts as Valid Written Identification

Valid identification must be in writing, signed by the investor, and delivered to the qualified intermediary, the seller of the replacement property, or another party involved in the exchange who is not a disqualified person, such as the investor's real estate agent or accountant acting in that capacity. The identification must describe the property unambiguously, typically by street address or legal description. A verbal mention to a broker, a text message describing a neighborhood, or a general statement of interest does not satisfy the requirement. We coordinate with the qualified intermediary to confirm that identification letters are received and time stamped before midnight on day forty-five, since the deadline is not extended if it falls on a Saturday, Sunday, or holiday.

Because San Francisco, CA property records and county recorder timelines can add friction to due diligence, we help investors organize a Bay Area target list early, track back up identifications under the two hundred percent rule, and confirm that each identified property description will hold up if the exchange is later reviewed. Missing the forty-five day deadline in a partial or full exchange generally means the transaction fails as a 1031 exchange and the deferred gain becomes taxable in the year of the relinquished sale.
