A 1031 exchange is a tax-deferral strategy that lets you sell an investment property and roll the profits into a new one without paying capital gains taxes — essentially a legal way to kick the tax bill down the road indefinitely.

Named after Section 1031 of the tax code, this has been a foundation of real estate investing since 1921. Sell a $400,000 rental you bought for $250,000, and instead of paying $30,000-$45,000 in federal and state taxes on the $150,000 gain, you reinvest into another property and owe zero. Right now, at least.

The Key Rules

Both the sold property and the replacement must be “like-kind” investment real estate. Rentals, commercial buildings, raw land, and apartment complexes all qualify. Your primary residence doesn’t.

The replacement property must cost at least as much as the one you sold. Any cash you pocket — called “boot” — gets taxed. All proceeds must flow through a Qualified Intermediary (QI), never through your personal accounts.

Critical Deadlines

Two non-negotiable timelines run from the day you sell:

  • 45 days: Identify up to three replacement properties in writing
  • 180 days: Close on at least one of those identified properties

Miss either deadline and the exchange fails. No extensions, no exceptions, no matter the reason. These deadlines include weekends and holidays.

What Gets Deferred

A 1031 exchange postpones federal capital gains tax (15-20%), depreciation recapture tax (25%), and the 3.8% net investment income tax. On a property with $200,000 in gains and $80,000 in accumulated depreciation, the total tax bill could exceed $70,000. That’s serious money staying invested instead of going to the IRS.

The End Game

You can chain 1031 exchanges together indefinitely — selling and buying, each time deferring taxes. If you hold the final property until death, your heirs get a stepped-up basis, and all those deferred taxes disappear permanently. This “swap till you drop” approach is how multigenerational real estate wealth survives.

Real-World Example

You sell a rental property for $500,000 that you originally purchased for $300,000. Without a 1031 exchange, you owe capital gains tax on the $200,000 profit — roughly $50,000-$60,000 in combined federal and state taxes. Using a 1031 exchange, you identify a $650,000 replacement property within 45 days and close within 180 days. A qualified intermediary holds the sale proceeds throughout — you never touch the money. Tax due now: $0. The entire gain is deferred into the new property. If you do another 1031 at your next sale, and continue until death, your heirs inherit the property with a stepped-up cost basis, potentially eliminating the tax entirely.

Frequently Asked Questions

What are the deadlines for a 1031 exchange?

You have 45 days from the sale of your relinquished property to identify up to three potential replacement properties (or more under certain value rules). You must close on a replacement property within 180 days of the sale. Both deadlines are firm — missing either one disqualifies the exchange and triggers the full tax liability.

Can I do a 1031 exchange on my primary residence?

No. Section 1031 applies only to investment or business-use property. Your primary residence does not qualify. However, if you convert a rental property to a primary residence (or vice versa), complex rules apply regarding holding periods and partial exclusions. Consult a tax advisor for mixed-use scenarios.
