A qualified opportunity zone business must satisfy more than a location test. In general, it needs at least 70% of its owned or leased tangible property to qualify as QOZ business property, at least 50% of gross income from active business in a zone, substantial use of intangible property there, less than 5% nonqualified financial property, and no prohibited business activity. Each test needs separate evidence.
This distinction matters because a Qualified Opportunity Fund, or QOF, may count stock or a partnership interest toward its own 90% investment standard only when the underlying entity qualifies as a QOZ business for the required holding period. A building inside a designated tract does not establish that result by itself.
What Are the Qualified Opportunity Zone Business Requirements?
The IRS instructions for Form 8996 summarize five operating requirements. A QOZ business must meet the 70% tangible-property standard, the 50% gross-income test, the substantial-use test for intangible property, the limitation on nonqualified financial property, and the exclusion of specified prohibited businesses.
The tests operate at different levels. The 70% test classifies the business’s tangible-property base. The gross-income and intangible-property tests connect activity to the zone. The financial-property rule limits passive holdings, subject to working-capital provisions. The prohibited-business rule disqualifies certain activities regardless of the other percentages.
IRS Notice 2026-40 confirms these core requirements while providing transitional guidance for the amended, recurring designation framework. For property and entity interests acquired after December 31, 2026, applicable start dates and tract status require specific review. Sponsors should not assume that an entity formed under the original program can apply every acquisition-date rule unchanged.
Test 1: At Least 70% of Tangible Property Must Qualify
The numerator is the value of tangible property owned or leased by the business that qualifies as QOZ business property. The denominator is the value of all tangible property it owns or leases. A simple illustration is:
$8.4 million qualifying tangible property ÷ $12 million total tangible property = 70%.
At exactly 70%, the hypothetical business meets this test. That does not mean it meets the other four requirements, or that every $8.4 million item was classified correctly.
Purchased property generally must be acquired under the applicable purchase rules, used in an active trade or business, and either begin its original use in the zone with the business or be substantially improved. During at least 90% of the holding period, at least 70% of the property’s use must be in a QOZ. The IRS explains that the combined time-and-use thresholds equal at least 63% over the entire holding period, but the business should test the two requirements separately rather than rely on a single blended percentage.
Leased property can qualify when the lease and use requirements are satisfied. Related-party leases carry added conditions, including limits on prepayment and, for certain previously used tangible personal property, a requirement to purchase additional qualifying property. Inventory may be included or excluded consistently from both sides of the annual calculation. Mobile property also has special usage and safe-harbor rules.
Primior’s property-level substantial-improvement guide addresses the separate basis calculation for acquired buildings. The 70% test then places each qualifying or nonqualifying asset into a business-level ratio.
Test 2: At Least 50% of Gross Income Must Come From Active Zone Business
Each taxable year, at least half of the entity’s gross income must derive from the active conduct of a trade or business in one or more QOZs. Revenue from customers outside the zone is not automatically disqualifying. The issue is where the business activity that produces the income occurs.
The IRS Opportunity Zone FAQs describe three safe harbors. A business can satisfy the test when at least 50% of the services received by it, measured by hours, are performed in QOZs; when at least 50% of amounts paid for services are for services performed in QOZs; or when the tangible property and management or operational functions necessary to generate the income are located in QOZs. Meeting any one safe harbor is sufficient. Facts and circumstances may support qualification outside them.
A credible file should connect payroll, contractor records, time data, work locations, management functions, customer contracts, and revenue recognition. A headquarters address is weak evidence when employees, equipment, and decision-making are dispersed.
Test 3: A Substantial Portion of Intangible Property Must Be Used in the Zone
At least 40% of the entity’s intangible property must be used in the active conduct of its QOZ business under the current QOF and QOZ business regulations. Relevant property can include software, operating systems, trade names, licenses, intellectual property, customer data, and contractual rights, depending on the business.
The analysis should identify what intangible property the entity owns or licenses, how it supports revenue, where the people and functions using it are located, and whether it is deployed in the active business rather than merely held. A real estate operating entity may have fewer material intangibles than a technology-enabled operating company, but it should still document the conclusion.
Test 4: Nonqualified Financial Property Must Remain Below 5%
Less than 5% of the average aggregate unadjusted basis of the entity’s property may consist of nonqualified financial property. The category generally includes debt, stock, partnership interests, options, futures, forwards, warrants, notional principal contracts, annuities, and similar property, subject to statutory and regulatory exclusions.
Reasonable working capital held in cash, cash equivalents, or certain short-term debt instruments can receive different treatment when the regulatory conditions are met. The exception is operational, not automatic. It depends on a written designation, reasonable schedule, and substantially consistent use.
Primior’s Opportunity Zone working-capital framework explains how to connect those requirements to budgets, contracts, draws, and project delivery. Sponsors building or capitalizing a QOZ business can work with Primior to assess the entity structure, qualifying property, operating plan, and evidence needed for execution alongside independent tax, legal, accounting, and other advisers.
Test 5: The Business Cannot Be a Prohibited Activity
A QOZ business cannot operate a private or commercial golf course, country club, massage parlor, hot-tub facility, suntan facility, racetrack or other gambling facility, or a store whose principal business is selling alcoholic beverages for consumption off premises. This is an activity test, not a general moral or quality judgment.
Mixed-use property requires attention to the operating entity and revenue streams. The presence of an excluded tenant does not necessarily produce the same result as the QOZ business itself conducting a prohibited business. Entity boundaries, leases, management, common ownership, and the actual trade or business should be reviewed rather than inferred from the property address.
A Five-Test QOZ Business Example
Assume a subsidiary partnership operates a light-industrial property and service business in a QOZ. It owns or leases $15 million of tangible property, of which $11.25 million qualifies. Its tangible-property ratio is 75%.
The entity earns 62% of gross income under a supported safe-harbor method, uses 55% of identified intangible property in the zone business, and holds nonqualified financial property equal to 2% of the relevant property basis. It conducts no prohibited business. On those simplified assumptions, it clears all five thresholds.
Now assume $2 million of equipment previously classified as qualifying is used mostly outside QOZs and fails the applicable mobile-property rules. Qualifying tangible property falls to $9.25 million, or 61.7% of the $15 million total. The business fails the 70% test even though its income, intangible-property, financial-property, and activity tests remain unchanged.
This example is hypothetical. Valuation methods, testing periods, ownership, leases, working capital, property use, and post-2026 transition rules can change the result.
Build a QOZ Business Qualification File
A defensible file should contain a legal-entity chart; acquisition and lease dates; tract verification; a tangible-property register; asset values and valuation method; original-use or substantial-improvement support; property-use records; gross-income safe-harbor workpapers; an intangible-property inventory; a nonqualified-financial-property calculation; working-capital documents; and a prohibited-business certification.
The file should also reconcile to the QOF’s testing and reporting process. Primior’s QOF reporting requirements guide explains how investee-business, tract, asset, housing, employment, and disposition information flows upward to the fund. A QOZ business does not file Form 8996, but the QOF needs sufficient evidence to support the qualifying status of an interest counted in its 90% investment test.
Qualification should be monitored, not decided once. New assets, dispositions, leases, remote employees, changed revenue sources, excess cash, intellectual-property transfers, and new business lines can affect different tests at different times. A quarterly internal review, followed by a formal annual tax review, can identify issues before records disappear or corrective options narrow.
Compliance and Underwriting Must Reach Separate Conclusions
Meeting the qualified opportunity zone business requirements does not establish that the company or property is attractively priced, adequately capitalized, competently managed, or likely to produce a return. Compliance determines whether the entity can support the intended tax structure. Underwriting determines whether its assets, demand, margins, financing, management, and downside capacity support an investment.
Investors, owners, and sponsors seeking both disciplines can work with Primior to evaluate the QOZ business structure, asset-level economics, capitalization, and execution controls with qualified tax, legal, accounting, valuation, engineering, and other professional advisers.
