What Is a QOF?
Last updated: March 2026What Is a Qualified Opportunity Fund?
A Qualified Opportunity Fund (QOF) is a corporation or partnership that self-certifies its status with the IRS and holds at least 90% of its assets in qualifying Opportunity Zone property. It is the investment vehicle through which investors access the OZ tax benefits.
How a QOF Works
Investors contribute eligible capital gains to the QOF in exchange for an equity interest (stock or partnership units). The QOF then deploys that capital into qualifying Opportunity Zone property or businesses.
A QOF does not require IRS pre-approval. It self-certifies by filing IRS Form 8996 annually with its tax return. The form includes the 90% asset test calculation.
The 90% Asset Test
A QOF must hold at least 90% of its total assets in qualifying Opportunity Zone property. This is tested semi-annually — on the last day of the first six months of the tax year (typically June 30) and on the last day of the tax year (typically December 31).
If the QOF fails the 90% test on either testing date, the fund owes a monthly penalty on the shortfall amount. The penalty is calculated per month and reported on Form 8996. Repeated failures can put the fund's qualified status at risk.
What Counts as Qualifying Property
The 90% threshold can be met with:
- Qualified Opportunity Zone Business Property (QOZBP): Tangible property (real estate, equipment) used in a trade or business located in an OZ — if the fund holds it directly (single-tier structure)
- Equity interests in a QOZB: Stock or partnership interests in a Qualified Opportunity Zone Business (most common in development-oriented funds)
Single-Tier vs. Two-Tier Structure
Single-tier: QOF holds property directly. Simpler but rarely used for new development or rehabilitation because QOFs cannot access the Working Capital Safe Harbor — meaning cash held during construction fails the 90% test.
Two-tier (industry standard): QOF holds equity in a QOZB subsidiary. The QOZB holds the real estate or operating business and can access the Working Capital Safe Harbor for up to 31 months (or 62 months with sequential infusions), legally holding construction cash without violating compliance rules.
