1031 Exchanges: Deferring Tax When You Sell Investment Property

May 25, 2026

Clients call me all the time with the same problem. They own investment property that has appreciated well beyond what they paid for it, and they want to sell. Then they see what the tax bill would look like and they stop cold. A properly structured Section 1031 exchange can let you sell and reinvest without paying that tax right now.

I have handled these exchanges for years, and the mechanics are not complicated once you understand the framework. But the deadlines are unforgiving, and small missteps can blow up the entire deferral. Here is what you need to know before you sign a listing agreement.

1. The property has to be held for investment or business use

Section 1031 only applies to real property held for investment or used in a trade or business. Your personal residence does not qualify. A second home you rarely rent out is a gray area that can get you in trouble.

Rental property, raw land held for investment, and commercial buildings are the classic candidates. The intent behind how you held the property matters, so I want to see a track record that supports an investment purpose before we start planning an exchange.

2. The replacement property must be like-kind real estate

Like-kind is broader than most people assume. Since the last major overhaul of this rule, real property exchanged for other real property generally qualifies, whether you are trading an apartment building for raw land or a retail strip center for farmland.

What no longer qualifies is personal property. If your deal involves significant equipment, vehicles, or other non-real-estate assets, we need to look closely at what is eligible and what is not.

3. You need a qualified intermediary, and you need one before you close

You cannot touch the sale proceeds and still defer the gain. The money has to go to a qualified intermediary, who holds it and uses it to acquire the replacement property on your behalf.

This has to be set up before your relinquished property closes. I have seen sellers close first and ask about a 1031 exchange afterward. At that point, the opportunity is gone. There is no fixing it after the fact.

4. The deadlines are fixed and they do not bend

Once you close on the property you are selling, you have 45 days to identify potential replacement properties in writing to your qualified intermediary. You then have 180 days from that same closing to complete the purchase of the replacement property.

These deadlines run on calendar days, not business days, and they do not pause for holidays, financing delays, or a deal falling through. I encourage clients to have replacement property lined up, or at least under serious consideration, before the first property ever closes.

5. Common mistakes that cost people their deferral

The most common mistake is waiting too long to bring in a qualified intermediary and an attorney. The second is misidentifying replacement property or missing the 45-day window because nobody was tracking it closely.

I also see people forget that the debt on the replacement property generally needs to equal or exceed the debt that was paid off on the relinquished property, or they need to bring cash to make up the difference. Getting the numbers wrong can create unexpected taxable gain even when you thought the exchange was clean.

A 1031 exchange rewards planning and punishes improvisation.

Getting the structure right from day one is far easier than trying to fix it after closing.
