What is a 1031 exchange?

A 1031 exchange (like-kind exchange) lets you defer capital gains taxes when you sell investment real estate and reinvest the proceeds into a similar property within strict IRS timelines.

Can I do a 1031 exchange on my primary residence?

No. 1031 exchanges only apply to investment or business-use properties. Your primary residence does not qualify.

What happens if I miss the 1031 exchange deadline?

If you miss the 45-day identification window or the 180-day closing deadline, the exchange fails and you owe capital gains taxes on the full sale amount.

1031 Exchanges: Deferring Capital Gains on Real Estate

A high-level overview of like-kind exchanges and their strict timelines.

Last updated on February 13, 2026

A 1031 exchange allows real estate investors to defer capital gains by reinvesting in a like-kind property.

Key Takeaways

Strict timelines apply: 45-day identification and 180-day close.
You must use a qualified intermediary.
Only investment or business properties qualify.

Why It Matters

Deferring gains allows more capital to stay invested, which can compound over time. The rules are strict, but you can navigate them yourself by following the timelines and using a qualified intermediary (required for the exchange). Compare the trade-offs against other capital gains tax strategies and your effective tax rate.

DIY Checklist: Questions to Answer

Does the property qualify as investment or business-use real estate?
Can I identify replacement properties within 45 days?
Can I close on the replacement within 180 days?
Have I selected a qualified intermediary before the sale closes?

How a 1031 Exchange Works

A 1031 exchange follows a precise sequence:

Sell your investment property. Proceeds go to a qualified intermediary (QI)---you cannot touch the money.
Identify replacement properties within 45 days. You can identify up to three properties (or more under certain rules).
Close on the replacement property within 180 days of the original sale.
Report the exchange on Form 8824 with your tax return.

The replacement property must be of “like kind,” which for real estate is broadly defined---an apartment building can be exchanged for raw land, a warehouse, or a retail property.

Common Pitfalls

Boot: If you receive cash or non-like-kind property in the exchange, that portion (called “boot”) is taxable.
Mortgage differences: If your replacement property has a smaller mortgage, the difference may be treated as boot.
Related-party rules: Exchanges between related parties have a two-year holding requirement.
