Opportunity Zone tax benefits, explained

The three benefits are deferral, a basis step-up and a permanent exclusion of appreciation, all in IRC §1400Z-2.¹ Each one is earned by holding a Qualified Opportunity Fund (QOF) investment for a set period. They apply to amounts invested on or after January 1, 2027.^2,3

You can defer the gain for up to five years. For amounts invested on or after January 1, 2027, the deferred gain is included in income in the tax year that includes the earlier of the date you sell or exchange the QOF investment or the date five years after you made it.^1,3 An investment made in March 2028 is taxed no later than March 2033.

The amount included is the lesser of the deferred gain or the investment's fair market value on the inclusion date, minus your basis in the investment.^1,5 Your basis starts at zero for the gain portion. If the fund has lost value, you pay tax on less.

Deferral is worth more than it looks. Five years of tax-free use of the money that would have gone to the IRS compounds inside the fund. The gain keeps its character: a deferred short-term gain is taxed as short-term when included. Detail in how the five-year deferral works.

The step-up is a 10% increase in your basis after you hold the QOF investment for five years, which means 10% of the deferred gain is never taxed. In a Qualified Rural Opportunity Fund (QROF), a QOF with at least 90% of its assets in wholly rural zones, the step-up is 30%.^1,4,6

A standard QOF investor in this example pays $214,200 at year 5; a QROF investor pays $166,600. The step-up is earned only by holding for the full five years. An investor who sells at year 4 pays tax on the whole deferred gain, and a fund that falls below the rural 90% test does not deliver the 30% figure, so rural investors should ask how the sponsor monitors that test. See the 10% and 30% basis step-up.

If you hold the QOF investment for at least 10 years, you can elect when you sell or exchange it to treat your basis as equal to its fair market value on that date.¹ The result is no federal capital gains tax on the appreciation. For a partnership QOF, the regulations also let investors exclude gain from the fund's own sale of its assets after the 10-year mark, which makes asset-level exits workable.⁹

The exclusion has a 30-year horizon. For a sale after the 30th anniversary of the investment, basis is fixed at fair market value on that anniversary, so growth after year 30 is taxable.^1,4 How the 30-year valuation is determined and elected when there is no sale is still open: Treasury's Notice 2026-55 requested comments on exactly that, due November 23, 2026.¹⁰

For most investors the exclusion is the main prize, because it applies to all of the new growth, not just the old gain. See the 10-year hold and the 30-year limit.

In a simple illustration, a QOF leaves an investor about 33% more after-tax wealth after 10 years than paying the tax and reinvesting in a taxable account with the same return.

1. 1.Taxable path: pay $238,000 now, invest $762,000, grow to $1,524,000, pay $181,356 on the $762,000 gain. Net: $1,342,644.
2. 2.Standard QOF: invest $1,000,000, grow to $2,000,000, pay $214,200 at year 5, nothing on the $1,000,000 of growth. Net: $1,785,800.
3. 3.Rural fund: same, but the year-5 tax is $166,600. Net: $1,833,400.

The gap widens with longer holds and higher returns, and narrows if the project underperforms. A more detailed model is in a worked Opportunity Zone tax savings example.

Yes, a few, mostly from how the rules interact with the rest of the tax code. None of them is a separate election; they follow from the structure of a partnership QOF and the 10-year basis rule.

• Depreciation: a partnership QOF can pass depreciation through to investors, and 100% bonus depreciation, made permanent for property acquired after January 19, 2025, applies to qualifying equipment and improvements. Because the 10-year election sets basis to fair market value, the usual recapture on exit is generally avoided on a sale of the QOF interest.¹¹
• Estate planning: death is not an inclusion event. The heir takes over the deferred gain and the decedent's holding period.¹²
• No dollar cap: there is no limit on how much gain an investor can defer, and no income limit.

See depreciation, bonus depreciation and Opportunity Zones.

Selling or otherwise disposing of the QOF interest early, or the fund losing its status, are the main risks. Inclusion events that accelerate the deferred gain include a sale or exchange, a gift (other than to a grantor trust) and distributions in excess of basis, including some debt-financed distributions.¹² A fund that fails its asset test repeatedly can be decertified.

State taxes are a separate question. California does not conform to the federal deferral or exclusion, so a California resident pays state tax on the gain in the year of sale.¹³ See inclusion events and state tax treatment.

Data centers combine large upfront capital, heavy depreciation and long-term value, which is the profile the exclusion rewards most. A campus that takes two to three years to build and lease up has seven or more years of stabilized operation before the 10-year mark, and its exit value is excluded from federal tax. Short-lived equipment depreciates quickly, and bonus depreciation can shelter operating income along the way.¹¹ OZ Data Centers sponsors funds of this kind; data centers in Opportunity Zones covers the structuring.
