Key Takeaways
- • A 1031 exchange defers, not eliminates, capital gains tax on investment property
- • Both properties must be like-kind real estate held for investment or business
- • Identify replacements within 45 days; close within 180 days
- • Proceeds must pass through a qualified intermediary, never your account
- • Your primary residence does not qualify
A 1031 exchange is one of the most powerful tools in US real estate investing because it lets you move equity from one property to the next without the IRS taking a cut at each step. Used well, it compounds your capital over a lifetime of trades instead of paying tax at every sale.
How a 1031 Exchange Works
You sell an investment property, but instead of receiving the cash, a qualified intermediary holds the proceeds. You then buy a replacement property of equal or greater value and debt. As long as you meet the rules, the gain is deferred until you eventually sell without exchanging.
The 2026 Timelines You Cannot Miss
Two clocks start the day you close the sale of your old property:
- 45 days: Identify potential replacement properties in writing to your intermediary.
- 180 days: Close on one or more identified properties. If your tax return is due earlier, that earlier date wins.
Miss either deadline and the entire exchange fails. Build in buffer time; do not cut it close.
What Qualifies as Like-Kind?
For US real estate, like-kind simply means real property exchanged for real property. A rental condo can become a strip mall, a duplex, or vacant land. The properties must both be held for investment or business; your own home, a fix-and-flip, or a property you merely hold for resale generally do not qualify.
Value Rules: Equal or Up
To fully defer tax, the replacement property must cost at least as much as the net sale price, and your new debt must be at least as large as the old debt paid off. If you take any cash out, that boot is taxed in the year of the exchange.
Plan With the Right Tools
Before you trade up, estimate where values are heading with the Home Value Appreciation Calculator, and model your closing costs with the Closing Cost Estimator so the math works in your favor.

Frequently Asked Questions
What is a 1031 exchange?
A 1031 exchange (named after IRS Section 1031) lets real estate investors sell a property and reinvest the proceeds into a similar, or like-kind, property while deferring capital gains tax. You do not escape the tax forever, but you postpone it by rolling the gain forward into the new property.
What are the 1031 exchange timelines in 2026?
You must identify potential replacement properties within 45 days of selling the old property, and you must close on one or more of them within 180 days (or your tax filing deadline, whichever comes first). Missing either deadline disqualifies the exchange.
What properties qualify for a 1031 exchange?
Both the property you sell and the one you buy must be held for investment or business use and must be like-kind, which for US real estate simply means real property for real property. A rental house can exchange into a rental duplex, an office, or raw land. Your primary home does not qualify.
What happens to capital gains tax without a 1031?
Without an exchange, you owe capital gains tax on the profit, plus a possible 25% recapture on depreciation you claimed. Those bills can erase a large share of your gain, which is why investors use 1031 exchanges to keep more capital working.
Do I touch the money during the exchange?
No. The proceeds must go through a qualified intermediary, not your personal account. If you take constructive receipt of the cash, the exchange fails and the gain becomes taxable in that year.
