1031 Exchange Guide

What is a 1031 exchange?

A 1031 exchange, named after Section 1031 of the Internal Revenue Code, lets a real-estate investor sell an investment or business property and defer capital-gains and depreciation-recapture tax by reinvesting the proceeds into like-kind replacement property. Done right, it's one of the most powerful wealth-building tools in U.S. real estate.

How a 1031 exchange works

In a typical delayed exchange, the investor sells the relinquished property, and the sale proceeds go directly to a Qualified Intermediary rather than to the investor. The investor then has 45 days to identify potential replacement properties in writing, and 180 days from the sale to close on one or more of them. The QI uses the held funds to buy the replacement property, and the tax on the gain is deferred.

Both properties must be held for investment or for productive use in a trade or business. Since 2018, Section 1031 applies only to real property. Personal residences and property held primarily for resale don't qualify.

The key 1031 exchange rules

  • 45-day identification rule: replacement properties must be identified in writing within 45 calendar days of the sale.
  • 180-day exchange period: the purchase must close within 180 calendar days of the sale, or by the due date of the tax return for that year (including extensions) if earlier.
  • Three-property rule: identify up to three properties of any value; or use the 200% rule (any number of properties up to 200% of the relinquished value) or the 95% rule.
  • No constructive receipt: the investor can't touch the proceeds, which is why a Qualified Intermediary is required.
  • Equal or greater value: to defer all of the tax, buy replacement property of equal or greater value and reinvest all net proceeds. Cash or debt relief left over ("boot") is taxable.
  • Same taxpayer: the entity that sells must generally be the entity that buys.

Types of 1031 exchanges

Delayed exchanges are the most common. Reverse exchanges let an investor buy the replacement before selling, using an exchange accommodation titleholder. Improvement (build-to-suit) exchanges use exchange funds to improve the replacement property. Investors also use Delaware Statutory Trusts (DSTs) as passive, fractional replacement property.

Common mistakes

The most expensive errors are missed 45-day or 180-day deadlines, receiving the proceeds directly, identifying properties incorrectly and buying less than the relinquished property's value. State rules matter too: some states require withholding or claw back deferred gain when property is exchanged out of state.

Frequently asked questions

What is a 1031 exchange in simple terms?

It's a way to sell an investment property and buy another one without paying capital-gains tax right away, as long as you follow the IRS rules and use a Qualified Intermediary.

What are the 1031 exchange deadlines?

You must identify replacement property within 45 days of selling and close the purchase within 180 days of selling. The two periods run at the same time.

Do I need a Qualified Intermediary for a 1031 exchange?

Yes, for a standard delayed exchange. The QI holds the sale proceeds so you never have constructive receipt, which would make the gain taxable.

Can I do a 1031 exchange on my home?

Generally no. Section 1031 applies to real property held for investment or business use, not a primary residence.
