Opportunity Zone vs. 1031 exchange: which is better?

A 1031 exchange postpones tax by rolling one investment property into another; an Opportunity Zone investment postpones and reduces tax on any capital gain and then eliminates tax on the new investment's growth. Under IRC §1031, you generally do not recognize gain or loss when you exchange real property held for business or investment for like-kind real property.^1,2 Under IRC §1400Z-2, you defer an eligible gain by investing it in a Qualified Opportunity Fund (QOF) within 180 days.³

The IRS lists the 1031 timing rules plainly: identify replacement property within 45 days and receive it within 180 days or by your return due date, including extensions, whichever is earlier.² The OZ rules have no identification step and no intermediary, but they have a different discipline: the fund must invest in designated zones and pass ongoing asset tests.^3,4

It depends on whether you would ever sell. In an illustrative case the Opportunity Zone wins if the investor sells after 10 years, and the 1031 wins if the investor holds real estate until death, because heirs generally receive a fair market value basis under §1014.⁵

1. 1.1031: the $3 million rolls into a new property worth $6 million at year 10. Carryover basis is $2 million, so a sale triggers tax on $4 million: $952,000. Net: $5,048,000.
2. 2.Opportunity Zone: the $1 million gain goes into a QOF that grows to $2 million, tax-free on exit; the year-5 tax on $900,000 is $214,200. The $2 million principal grows to $4 million in a taxable account, with $476,000 of tax on the $2 million of growth. Net: $5,309,800.
3. 3.1031 held until death: no income tax for the investor or, generally, the heirs on the $6 million value.

Depreciation shifts the math further. A 1031 replacement property inherits the low basis of the property given up, while an OZ fund's new construction is depreciated from its full cost. See a worked OZ tax savings example.

• You want to keep owning and controlling real estate yourself.
• You plan to hold real estate for life and leave it to heirs, who generally take a stepped-up basis.⁵
• You have a large depreciation recapture exposure that a 1031 defers in full; under the OZ rules, §1245 recapture taxed as ordinary income cannot be deferred.⁶
• You can find suitable like-kind property within 45 days and close within 180.
• The best replacement property is not in a designated zone.

• Your gain is not from real estate: stock, a business sale, crypto or collectibles cannot go into a 1031 exchange.^1,7
• You want to take money off the table: you invest only the gain and keep the principal.
• You want new growth to be tax-free, and you can hold for at least 10 years.
• You cannot find 1031 replacement property in time, or a failed exchange has left you with a recognized gain.
• You want a professionally managed or diversified investment rather than another property to run.

The OZ route has costs to weigh: the deferred gain is taxed after five years whether or not you have sold, your money is locked up for a decade, and the fund's project must succeed. See the risks of Opportunity Zone investing.

Yes, in sequence. If a 1031 exchange produces taxable boot, such as cash kept or debt not replaced, the recognized gain is generally capital or §1231 gain that can be invested in a QOF within 180 days.^1,7 An investor can also split a sale: exchange part of the value into like-kind property and invest the gain on the rest in a QOF. What you cannot do is defer the same dollar of gain under both provisions, because gain deferred in a 1031 exchange is not recognized and so is not eligible gain.⁷

Real estate sellers face this choice most often; Opportunity Zones for real estate investors selling property works through the cases. Because the outcome depends on depreciation, debt, heirs and state tax, model both with your tax adviser before the sale closes.

For a property owner selling a data center or industrial site, a 1031 exchange into another stabilized property preserves real estate exposure. An OZ fund offers a way into new data center development, where most value is created during construction and lease-up and the 10-year exclusion captures it. New equipment and improvements also start with full basis for depreciation, including 100% bonus depreciation for qualifying property acquired after January 19, 2025.⁸ See data centers in Opportunity Zones.
