The QOF 90% asset test

The 90% asset test, also called the 90% investment standard, requires a Qualified Opportunity Fund (QOF) to hold at least 90% of its assets in Qualified Opportunity Zone property (QOZP). A QOF is a corporation or partnership organized to invest in QOZP that self-certifies on Form 8996.^1,4 The test in §1400Z-2(d)(1) is the fund's core ongoing requirement: an investor's deferral and 10-year exclusion depend on investing in an entity that qualifies as a QOF.

QOZP has three forms. The fund can hold Qualified Opportunity Zone business property directly, or it can hold stock or a partnership interest in a Qualified Opportunity Zone Business (QOZB), acquired for cash at original issue, where the entity qualifies as a QOZB during substantially all of the fund's holding period.^1,2 Most funds use a QOZB, which faces its own tests.

Twice a year: on the last day of the first six-month period of the fund's taxable year and on the last day of the taxable year. For a calendar-year fund, those are June 30 and December 31.^1,6 The fund's compliance percentage for the year is the average of the two.

The first year has special rules. A fund chooses the first month it is a QOF on its initial Form 8996. Under the regulations, if that month is after the sixth month of its taxable year, the year-end date is the only testing date for that year; otherwise the first six-month period is measured starting with the month the fund became a QOF.^2,3 Choosing a later start month can give a new fund time to deploy capital, but investors can only make qualifying investments in an entity once it is a QOF.

The fund values its assets using one of two methods, chosen each year and applied to all assets consistently for that year.^2,10

• Applicable financial statement method: values reported on an applicable financial statement, such as audited GAAP financial statements. Available only if the fund has one.
• Alternative valuation method: owned property is generally valued at its unadjusted cost basis; leased property is valued at the present value of the lease payments, fixed at the start of the lease.^10,12

Cost-based valuation means appreciation does not help or hurt the test, and it keeps the numbers stable between testing dates. Leased property is included in both the numerator and denominator when it qualifies, which matters for funds that lease land or equipment.¹⁰ The same valuation methods apply to the QOZB's 70% test.¹²

Two relief rules keep cash from failing the test, but neither is the 31-month working capital safe harbor, which is available only to QOZBs.^3,14

• Six-month rule for new capital: a QOF may exclude from the test property received as a contribution or for stock or partnership interests within the six months before the testing date, if it is held in cash, cash equivalents or short-term debt of 18 months or less.^3,6
• 12-month reinvestment rule: proceeds from the return of capital or sale of QOZP count as QOZP for the test if reinvested in QOZP within 12 months and held in cash, cash equivalents or short-term debt in the meantime. Extensions are available for federally declared disasters and certain government delays.^11,3

The 12-month rule protects the fund's status only. It does not defer tax on the gain from the sale, which flows to the partners unless the 10-year election applies. Notice 2026-55 asks whether interim gains should get more relief; until rules change, plan for the gain to be taxable.¹⁵

The penalty under §1400Z-2(f) is, for each month the fund fails, the amount by which 90% of its aggregate assets exceeds its QOZP, multiplied by the underpayment rate under §6621(a)(2) for that month, which is the federal short-term rate plus three percentage points.^1,6 Form 8996 computes it month by month using month-end values, divides the annual rate by 12, and treats a negative shortfall as zero.⁵

For a QOF partnership, the penalty is taken into account proportionately as part of each partner's distributive share.⁶ No penalty applies if the failure is due to reasonable cause. COVID-era notices treated failures on testing dates from April 1, 2020 through June 30, 2021 as reasonable cause, and that relief has expired.^8,9 Practitioners note that reasonable cause depends on facts and documentation, and that holding uninvested cash because no deal was found is a common way to fail.⁷

By moving cash to the QOZB quickly and letting the QOZB's working capital safe harbor carry the construction period. A data center campus can take years to energize; Dominion Energy has said connections for loads above 100 MW could take up to seven years in total in its territory.¹⁶ A QOF holding that cash itself would fail. A QOZB can hold it for up to 31 months per plan, or 62 months with multiple plans, under a written schedule.²

Capital-call timing matters too. Investors have 180 days from their gain to invest in the QOF; the fund then has the six-month window before cash counts against it. Matching calls to the QOZB's spending schedule keeps both tests clean. See the working capital safe harbor, the QOZB 70% tangible property test and data center power timelines and the Opportunity Zone clock.

On Form 8996, filed with the fund's return every year, including the year it decertifies. The form reports QOZP and total assets on each testing date, the resulting percentage and any penalty.^4,5 Under proposed regulations, Form 8996 would become a separate information return with census-tract-level data; those rules are not final.¹³ See Form 8996 and Form 8997, explained and Opportunity Zone reporting requirements and penalties.
