What counts as 'like-kind' for a 1031 exchange?

For US investment real estate, like-kind is broadly defined. A single-family rental can exchange into a multifamily building, raw land, a commercial property, or a net-lease retail property. The main requirement is that both properties are held for investment or business use. Foreign real estate is not like-kind to US real estate.

What happens if I miss the 45-day or 180-day deadline?

Missing either deadline disqualifies the exchange, and the gain from the original sale becomes taxable in the year of that sale. The IRS does not grant extensions for market conditions or deal delays. The 45-day clock and the 180-day clock both run from the day you close on the relinquished property.

What is a qualified intermediary and why is it required?

A qualified intermediary (QI) is an independent third party who holds the sale proceeds between closing on the relinquished property and closing on the replacement property. The investor cannot receive, touch, or control the funds during the exchange period — doing so disqualifies the exchange. Title companies, exchange facilitators, and certain trust companies act as QIs.

Does a 1031 exchange eliminate capital-gains tax permanently?

No, it defers it. The deferred gain is built into your cost basis in the replacement property. When you eventually sell without another exchange, tax on the accumulated deferred gain is due. Investors who hold through death may pass a stepped-up basis to heirs that can wipe out the deferred gain, though this corner of the code is revisited often.

1031 exchange in real estate, explained

What a 1031 exchange defers

When you sell an investment property at a gain, the federal government wants its share. Long-term capital-gains rates range from 0% to 20% depending on taxable income, and on top of that many investors owe the 3.8% net investment income tax. State taxes may apply too. On a $200,000 gain, total federal tax exposure for a high-income investor can exceed $47,000 before any state tax.

A 1031 exchange lets you roll that full gain, untaxed, into the next property. You don’t avoid the tax for good. It rides along in your cost basis and comes due when you finally sell without rolling into another exchange. Deferred tax is capital you keep working, and investors have used a series of exchanges to compound returns for years without triggering the gain.

The two deadlines that cannot move

The IRS imposes strict timing on 1031 exchanges, and neither deadline is flexible.

45-day identification deadline. After you close on the sale of your relinquished property, you have exactly 45 calendar days to identify potential replacement properties in writing to your qualified intermediary. Most investors name up to three properties (the “three-property rule”), though you may identify more under other IRS rules that impose additional constraints. Verbal identification does not count.

180-day closing deadline. You must close on at least one identified replacement property within 180 calendar days of the sale of the relinquished property. The 180-day clock does not restart after the 45-day identification window closes; both run from the same starting date.

Miss either deadline and the exchange fails. The IRS does not offer extensions for failed deals, cold-footed sellers, or title problems.

The qualified intermediary requirement

You cannot receive the sale proceeds, even briefly. The moment the money passes through your hands, the IRS treats it as a taxable sale. A qualified intermediary receives the funds when you sell, holds them for the exchange period, and delivers them to the seller of the replacement property at closing.

Line up a QI before you close on the relinquished property, because the arrangement must be in place at the time of sale. QI fees commonly run several hundred to roughly fifteen hundred dollars for a straightforward exchange.

What “like-kind” means in practice

The term sounds restrictive; for US investment real estate, it isn’t. Any real property held for investment or business use in the United States qualifies. A duplex can roll into a commercial strip center, or vacant land into an apartment building. The property type does not need to match — only the use (investment or business) and the location (US) do.

What does not qualify: your primary residence, a vacation home you use personally beyond the allowable threshold, property outside the US, and personal property (the 2017 Tax Cuts and Jobs Act ended personal-property exchanges). Raw land with no improvements is still eligible as long as you hold it for investment rather than personal use.

Trading down and “boot”

If the replacement property costs less than the net proceeds from the sale, or if you receive any cash back at closing, the difference is called “boot.” Boot is taxable to the extent of the gain. To fully defer the gain, the replacement property must cost at least as much as the net sale price, and all of the equity must be reinvested.
