Selling an appreciated rental or commercial property usually triggers a capital-gains tax bill. Section 1031 of the Internal Revenue Code offers a way to defer that tax: exchange your property for another "like-kind" investment property, and the IRS lets you roll your gain forward instead of paying it now.
Like-kind requirement
Real property held for investment or business use qualifies. A residential rental can exchange into a retail strip center, vacant land into an apartment building, or an office into a warehouse—all are considered like-kind under current law. Your primary residence and property held primarily for resale (fix-and-flip inventory) do not qualify. Both the property you sell (the relinquished property) and the property you buy (the replacement property) must be in the United States and held for investment or business purposes.
The 45-day identification window
You have exactly forty-five calendar days from the date you close the sale of your relinquished property to identify potential replacement properties in writing to your qualified intermediary. Most investors identify up to three properties of any value (the three-property rule), though other identification tests exist. Miss the forty-five-day deadline and the exchange fails; the gain becomes taxable.
The 180-day closing window
You must close on one or more of your identified replacement properties within one hundred eighty calendar days of selling the relinquished property—or by the due date of your tax return for that year, whichever is earlier. Extensions to file your return do not extend the exchange period. The clock starts the day your relinquished property closes and does not pause for weekends or holidays.
The qualified-intermediary role
You cannot touch the sale proceeds and still preserve the exchange. A qualified intermediary—a third-party facilitator who is not your agent, attorney, accountant, or certain relatives—holds the funds in a segregated account between the sale and the purchase. You assign your sale contract to the intermediary, who receives the proceeds at closing, then uses those funds to acquire the replacement property on your behalf. Direct or constructive receipt of cash disqualifies the exchange.
Boot and partial taxability
If you receive cash, debt relief, or non-like-kind property as part of the exchange, that excess is called boot, and it is taxable in the year of the exchange. To defer one hundred percent of the gain, the replacement property must be equal or greater in value and equity, and you must reinvest all net proceeds. Trading down in value or taking cash out creates a taxable event on the portion not reinvested.
The Alliance take
A 1031 exchange is a powerful estate-building tool when executed correctly, but the timelines are unforgiving and the rules are technical. Consult a CPA or attorney; this is not tax or legal advice.
