How to qualify for QoZ?

Direct answer: You qualify for the Qualified Opportunity Zone (QOZ) program at three separate levels: your capital gain must be reinvested through a certified Qualified Opportunity Fund (QOF), that fund must hold at least 90% of its assets in qualifying opportunity zone property, and any underlying business or property must meet its own set of location and use tests. Meeting these tests correctly, and being able to document the fair market value of your resulting interest, is what determines whether your investment holds up under IRS scrutiny.

What it takes to qualify

You reinvest a capital gain. Only capital gains, reinvested within 180 days into a QOF, are eligible for deferral under IRC 1400Z-2.
The fund is a certified QOF. The entity must be a corporation or partnership that self-certifies as a QOF by filing Form 8996 and maintains that status annually.
The fund passes the 90% asset test. At least 90% of the QOF's assets, tested semiannually, must be qualifying opportunity zone property: QOZ stock, QOZ partnership interests, or QOZ business property.
The underlying business or property meets its own tests. This includes location within a designated zone, substantial improvement or original-use requirements, and limits on the percentage of tangible property held outside the zone.

None of these tests are self-executing. A fund's manager, an LP, or a CPA typically needs to confirm the asset test is being met year over year, and this is where valuation work becomes necessary: you cannot demonstrate a 90% asset threshold, or defend the basis of your LP interest, without an accurate fair market value.

Where valuation fits into qualification

Qualifying is a legal and structural question, but once you hold an interest in a QOF, a qualified opportunity fund valuation documents what that interest is actually worth. This matters most at the December 31, 2026 inclusion event, when deferred gain must be recognized whether or not you've sold your interest, and at any point a fund reports to auditors, transfers an interest, or resolves a partner dispute. A USPAP-compliant valuation, prepared using Rev. Rul. 59-60 methodology and accounting for minority-interest discounts, gives your CPA or tax attorney a defensible number to work from rather than an estimate.
