How Does OZ Investing Work?
Last updated: March 2026How Does OZ Investing Work?
OZ investing works by allowing an investor to reinvest eligible capital gains into a Qualified Opportunity Fund within a 180-day window. If the fund and investment stay compliant and the investor holds for at least 10 years, post-investment appreciation is excluded from federal capital gains tax.
Step 1: Realize an Eligible Gain
The OZ program requires an eligible capital gain — not ordinary income. Qualifying gain types include:
- Real estate sales
- Stock sales (including publicly traded securities)
- Cryptocurrency transactions
- Business sale proceeds
- Partnership gains reported on a Schedule K-1
You only need to invest the capital gain portion, not the full sales proceeds. Your original cost basis can be kept and used freely.
Step 2: Invest Into a QOF Within 180 Days
The 180-day clock starts differently depending on how the gain was earned:
- Direct individual sales (stock, real estate, crypto): clock starts on the exact date of sale
- Partnership K-1 gains: the investor may elect to start the clock on the transaction date, December 31 of the tax year, or March 15 of the following year — whichever is most advantageous
This distinction matters enormously in 2026. An investor with a K-1 gain realized in 2026 can often elect to start their 180-day clock on March 15, 2027, allowing them to fund the QOF under OZ 2.0 rules and receive the rolling five-year deferral and 10% basis step-up instead of the zero step-up available in 2026.
Step 3: The QOF Deploys Capital
A QOF must hold at least 90% of its assets in qualifying Opportunity Zone property, tested semi-annually on June 30 and December 31 each year. Failing this test triggers compounding monthly penalties reported on IRS Form 8996.
Most development-focused OZ funds use a two-tier structure: the QOF invests into a subsidiary Qualified Opportunity Zone Business (QOZB), which owns and operates the project. The QOZB layer is critical because it — and only it — can access the Working Capital Safe Harbor, which allows the business to hold cash during construction for up to 31 months (or up to 62 months with sequential infusions).
Step 4: Hold and Manage for the Long Term
This is where most of the real risk sits:
- The fund must pass semi-annual compliance tests
- The QOZB must pass annual tests including the 70% tangible property test
- Documentation for the Working Capital Safe Harbor must be maintained with written plans and written deployment schedules
- The capital stack must survive a 10-year hold — bridge loans, mezzanine debt, and preferred equity that create refinancing pressure can force a premature sale and forfeit the tax-free exit
Step 5: The 10-Year Exit
If the QOF interest is held for at least 10 years, the investor may elect to step up their tax basis to fair market value on the date of sale. This:
- Eliminates all federal capital gains tax on appreciation above the original investment
- Eliminates depreciation recapture entirely — which in conventional real estate is unavoidable and taxed at up to 25%
- Under OZ 2.0, this FMV election is available for up to 30 years from the investment date, with a deemed step-up available on the 30th anniversary even without a sale
What Investors Often Miss
The phantom tax. The original deferred gain must be paid in real cash — either at the December 31, 2026 OZ 1.0 deadline (tax due April 2027) or five years from the investment date under OZ 2.0. Most funds will not distribute cash to cover this. Investors need outside liquidity.
Depreciation works differently here. Your initial tax basis in a QOF investment is $0. To claim depreciation deductions, the fund must allocate qualified non-recourse debt to your interest. A well-structured fund accounts for this. A poorly structured one often does not.
The OZ wrapper does not rescue a bad deal. The tax benefits only enhance an investment that already makes sense on pre-tax fundamentals.
