What Is a 1031 Exchange? How to Defer Taxes on Real Estate Investments

Named after Section 1031 of the tax code, a 1031 exchange lets real estate investors sell an investment property and reinvest the proceeds into a new one without paying capital gains tax right away. Instead of losing a chunk of your gains to taxes, you roll the full amount forward into your next property.

How a 1031 Exchange Works

You sell an investment or business property, then reinvest the proceeds into a 'like-kind' replacement property. The capital gains tax you would have owed is deferred, not eliminated — until you eventually sell without reinvesting.

The Strict Timeline

• 45 days after closing the sale to formally identify potential replacement properties
• 180 days total to close on the replacement property
• You must use a qualified intermediary to hold the funds — touching the proceeds yourself disqualifies the exchange

What Qualifies as 'Like-Kind'

• Any real property held for investment or business use qualifies for exchange with any other (an apartment building for retail space, land for a rental house)
• A personal residence does not qualify
• The same taxpayer must appear on both sides of the transaction

Why Investors Use It

• Defer capital gains tax indefinitely by repeating exchanges over time
• Upgrade to larger or better-performing properties without a tax drag on every trade
• Hold until death — heirs receive a stepped-up basis, permanently erasing the deferred gain

Risks and Costs

• Qualified intermediary fees add to transaction costs
• Finding a suitable replacement within the 45-day window can be difficult in a competitive market
• All debt and equity from the sold property must be replaced, or the shortfall ('boot') becomes taxable
• It defers tax — it doesn't eliminate it, unless used until death
