What is the 70% tangible property test for QOZBs?

The 70% tangible property test is one of five requirements a trade or business must satisfy to qualify — and remain qualified — as a Qualified Opportunity Zone Business (QOZB). It requires that at least 70% of the tangible property owned or leased by the business be Qualified Opportunity Zone Business Property (QOZBP).

The test is established in IRC §1400Z-2(d)(3)(A)(i), which requires that “substantially all of the tangible property owned or leased by the taxpayer is qualified opportunity zone business property.” The statute uses the term “substantially all” without defining it numerically — it is the Treasury regulations at 26 CFR §1.1400Z2(d)-1(d)(4) that assign the 70% threshold. Those regulations also cross-reference 26 CFR §1.1400Z2(d)-2 for the full definition of what qualifies as QOZBP.

Why This Test Matters

The 70% tangible property test ensures that a QOZB’s physical asset base is genuinely rooted in the Qualified Opportunity Zone. It prevents businesses from achieving QOZB status while holding the majority of their productive assets outside the zone. Along with the 50% gross income test, it is one of the two primary tests that tie QOZB status to real, on-the-ground economic activity within the designated area.

A business that fails this test cannot maintain QOZB status, which in turn can jeopardize the QOF’s compliance with the 90% asset test and the tax benefits available to investors.

What Counts as QOZBP

For tangible property to qualify as QOZBP and count toward the 70% threshold, it must satisfy three requirements under IRC §1400Z-2(d)(2)(D):

  1. Acquired by purchase after December 31, 2017 (or the applicable start date under OZ 2.0). Property contributed, inherited, or otherwise transferred on a carryover basis does not qualify.
  2. Original use commences with the QOF or QOZB, or the property is substantially improved. Either the property must be put to use in the Qualified Opportunity Zone for the first time by the QOF or QOZB, or the QOF or QOZB must substantially improve it after acquisition.
  3. Substantially all of the use of the property must be in a Qualified Opportunity Zone during substantially all of the holding period. For this purpose, “substantially all” means at least 70% of use within the zone during at least 90% of the holding period.

How the Test Is Measured

The 70% tangible property test is measured on a semiannual basis, consistent with the QOF’s 90% investment standard testing dates. This means the composition of a QOZB’s tangible property base is evaluated twice per year. Businesses must maintain the required threshold at each testing date — not just at the time of the QOF’s initial investment.

The test applies to both owned and leased tangible property. The Treasury regulations provide specific rules for how leased property is treated, including requirements around lease terms and related party restrictions.

The Relationship to the QOF’s 90% Asset Test

The 70% tangible property test operates at the QOZB level, while the 90% asset test operates at the QOF level. The two tests are interconnected: for a QOF that holds stock or a partnership interest in a QOZB, the value of that interest counts toward the QOF’s 90% asset test only if the QOZB satisfies its own compliance requirements — including the 70% tangible property test — for substantially all of the QOF’s holding period. A QOZB that falls out of compliance can therefore create a cascading compliance problem at the QOF level.

Practical Implications for Pre-Existing Businesses

The 70% tangible property test presents particular challenges for pre-existing businesses seeking Qualified Opportunity Zone equity. A business that was already operating before the QOF investment was made may have a significant base of tangible property that does not qualify as QOZBP — because it was acquired before December 31, 2017, or because it does not satisfy the original use or substantial improvement requirements. Such a business must either acquire sufficient new qualifying property to bring the ratio above 70%, or substantially improve existing property within the zone, to achieve and maintain QOZB status.

Bottom Line

The 70% tangible property test is the foundational asset-composition requirement for QOZB status. It must be satisfied at every semiannual testing date throughout substantially all of the QOF’s holding period, and it requires careful attention to what property qualifies as QOZBP and how the ratio is calculated. Fund managers and business owners should work with qualified tax counsel to monitor compliance with this test on an ongoing basis and to structure acquisitions and improvements in a way that supports continued qualification.
