The 45-Day Identification Period: A Complete Procedural Guide

The forty-five day identification period is the first of two statutory deadlines under Section 1031 of the Internal Revenue Code. It does not eliminate capital gains tax on the sale of investment real property. It defers that tax, provided the investor identifies qualifying replacement property within the required window and later completes the acquisition. Every exchange handled for clients in the Washington DC metro area is built around this deadline from the first day of planning.

How the Forty-Five Day Clock Starts

The clock begins the calendar day after the relinquished property closes and the qualified intermediary receives the sale proceeds. The count includes all calendar days, including weekends and federal holidays. There is generally no extension available, except in limited cases where the Internal Revenue Service issues formal disaster relief for a federally declared disaster affecting the property location.

Three Identification Methods

The Three Property Rule

An investor may identify up to three replacement properties of any value. Value is not a limiting factor under this method, only the number of properties identified.

The Two Hundred Percent Rule

An investor may identify more than three properties, provided the combined fair market value of all identified properties does not exceed two hundred percent of the fair market value of the relinquished property.

The Ninety-Five Percent Exception

An investor may identify any number of properties of any combined value, but must acquire at least ninety-five percent of the total identified value to keep the identification valid.

What the Identification Notice Must Contain

The notice must be a signed written document delivered to the qualified intermediary or to another party involved in the exchange who is not a disqualified person. It cannot go only to the seller of a prospective replacement property.

• An unambiguous description of each property, using a legal description, street address, or distinguishable name
• The signature of the investor identifying the property
• The date of delivery to the qualified intermediary or other permitted party
• A method of delivery that can be documented, such as certified mail, fax confirmation, or email with confirmed receipt

Washington DC Metro Timing Considerations

Property in submarkets such as Capitol Hill, NoMa, and the Navy Yard corridor can move through the market quickly, and closing schedules at the District of Columbia Recorder of Deeds can affect exactly when a qualified intermediary confirms receipt of the relinquished property proceeds. Investors relinquishing property in the District should also plan separately for DC transfer and recordation tax filings. These filings run on their own schedule and receive no extension because of the forty-five day identification window.

Consequences of a Missed Deadline

If a valid identification is not delivered within forty-five days, the entire exchange fails. The exchange funds held by the qualified intermediary become taxable, and the investor owes capital gains tax, and any applicable depreciation recapture, for the year in which the deadline passed. For an investor who is a District of Columbia resident, the recognized gain is also subject to the District graduated individual income tax, which taxes capital gains as ordinary income rather than at a separate lower rate. District rates rise with income and reach 10.75 percent for taxable income above $1,000,000, so a failed identification can create a combined federal and District tax burden well beyond the federal capital gains rate alone.

Revoking and Replacing an Identified Property

An investor may revoke an identification and substitute a different property, but only within the original forty-five day window. Once the forty-fifth day passes, the identification list is locked, and any replacement property ultimately acquired must be one of the properties named on that list. Investors working in competitive DC metro submarkets often identify the maximum number of properties allowed under the chosen rule for this reason, since a revocation after the deadline is not permitted even if a listed property later falls through.

Coordinating With a Tax Advisor Before the Clock Starts

Because the forty-five day period cannot be paused once it begins, the most effective planning happens before the relinquished property closes. Reviewing target submarkets, confirming financing capacity, and pre-screening candidate properties in the weeks before closing allows an investor to use the full forty-five days for due diligence rather than initial searching. A tax advisor familiar with District of Columbia filing requirements should also confirm how the exchange will be reported on the federal return and the District return for the year of the transfer.

Frequently Asked Questions

Can the forty-five day period be extended?

Generally no extension exists for the forty-five day identification period, except when the Internal Revenue Service issues formal disaster relief tied to a federally declared disaster affecting the property location. Investors in the Washington DC metro area should plan to identify property within the standard window rather than assume relief will apply.

Does the identification notice need to go to the seller of the replacement property?

No. The notice must go to the qualified intermediary or to another party involved in the exchange who is not a disqualified person under the Treasury Regulations. Sending the notice only to the seller of a prospective replacement property does not satisfy the requirement.

Can an investor identify property in a different state than the relinquished property?

Yes. Like-kind exchange rules for real property allow identification and acquisition of replacement property anywhere in the United States. An investor selling property in the District of Columbia may identify replacement property in Virginia, Maryland, or any other state.
