Investor WorkspaceA little clarity for your next decision.
By Jerry Baker
A Qualified Opportunity Zone Business, or QOZB, is a business that meets tax rules for its property, income, and operations in an Opportunity Zone. A Qualified Opportunity Fund can invest in that business, but a zone address alone does not make it qualify. This guide explains the business tests, working-capital rules, and changes that matter as the program moves from 2026 into 2027.
There are three separate levels to follow. The investor puts eligible gain into a Qualified Opportunity Fund, or QOF. The fund may then buy a qualifying ownership interest in a QOZB. That business uses the money to buy, build, lease, or operate the underlying assets. Each level has its own rules. Passing one level does not excuse a failure at another. [1]
For example, a fund might invest cash in a partnership that develops and operates apartments. The partnership, rather than the fund itself, holds the building. The fund tests its interest in the partnership. The partnership tests its property and operations. Meanwhile, each investor must meet the separate gain, timing, election, and holding-period rules.
A direct investment in a local business is not automatically a qualifying QOF investment. Nor does an LLC become a QOZB just because its name includes “Opportunity Zone.” Its tax status must fit its ownership, work, and assets. The offering should show who owns what. [1]
| Test | Basic requirement | Common mistake |
|---|---|---|
| Tangible property | At least 70% by value must qualify. | Counting only assets inside the zone. |
| Gross income | At least 50% must come from active business in the zone, applying the rules. | Testing only customer addresses. |
| Intangible property | At least 40% must be used in active business in the zone. | Ignoring software or other rights. |
| Financial property | Less than 5% under the specified basis test, with exceptions. | Assuming all cash is allowed. |
| Business activity | The business must be active and avoid prohibited activities. | Treating a passive lease as enough. |
These are summaries. A brochure alone cannot show that each test is met. Valuation methods, safe harbors, testing periods, and exceptions matter. The rules for the fund's interest also generally require the business to qualify during at least 90% of the fund's holding period. A business cannot ignore later changes after its first successful test. [1]
The numerator is the value of qualifying tangible property owned or leased by the business. The denominator includes all its tangible property, whether inside or outside a zone. “Tangible” means physical property, such as buildings, equipment, and furniture. Use the permitted valuation method, including the rules for leased property. Do not substitute a rough count of properties. [1]
Suppose a business has $10 million of tangible property under the proper valuation rules. Of that amount, $7.5 million is qualifying zone business property. Its ratio is 75%, which passes this test. If the qualifying amount falls to $6.8 million while the total stays $10 million, the ratio is 68%. That fails unless applicable relief or a safe harbor changes the result.
These figures are hypothetical. They assume the assets have already been classified correctly. A building can sit inside a zone yet fail a purchase, use, or improvement rule. Counting its full value as qualifying before that review can make an attractive ratio misleading.
The fund's separate 90% asset test does not replace the business's 70% test. Multiplying the percentages also does not give a manager a general license to move money anywhere. Income, use, cash, ownership, and holding-period rules still apply. Ask for the actual calculations at both levels. [1]
Owned property generally must be used in a trade or business, meet the applicable purchase rules, and satisfy original-use or substantial-improvement requirements. Its location and use over time matter too. Related-party rules are stricter than many buyers expect. The relevant ownership threshold in these rules substitutes 20% for certain ordinary 50% related-party thresholds. [2]
Original use generally starts when property is first placed in service in the zone for depreciation or amortization purposes. That can differ from when a deed is signed. Used equipment brought into the zone may meet original use if it was not previously used there. An existing building often needs a substantial-improvement analysis instead. Vacancy and certain other facts can create exceptions, but a broker's description of a building as “vacant” is not enough. [2]
For the normal improvement test, additions to basis must exceed the property's starting adjusted basis during the applicable 30-month period. When a building and land are bought together, land is excluded from the building's improvement threshold. That does not mean land can always be held idle. Trade-or-business and anti-abuse rules still matter. [2]
Assume a purchase has a supported $2 million building basis and $1 million land basis. Under the normal test, qualifying additions to the building's basis must exceed $2 million. Spending exactly that amount is not a comfortable reading of an “exceeds” requirement. A budget should also separate costs that add to basis from costs that do not.
Legislation enacted in 2025 lowered the substantial-improvement threshold for qualifying rural property. Notice 2025-50 addresses determinations made on or after July 4, 2025. Where its conditions apply, additions must exceed 50% of the starting adjusted basis, rather than the normal 100%. The 30-month period still matters. [3]
In the $2 million building example, that means more than $1 million of qualifying additions if the rural rule applies. It does not mean half the entire purchase price, including land. Nor does a small-town mailing address establish rural status. The notice uses a defined rural-area test and identifies qualifying existing zones.
Do not confuse this improvement rule with the separate 30% investor basis increase for qualifying rural fund investments made after 2026. Those benefits have different requirements and operate at different levels. A project can require a rural-property review even when the investor's own tax benefit is being analyzed under a different rule. [3][4]
A business does not need to own every building or piece of equipment. Qualifying leased property can count toward the tangible-property test. But the lease must meet the applicable acquisition-date, market-rate, use, and other rules. Owned-property requirements should not simply be copied onto leases. The regulations have a separate set of lease provisions. [2]
Related-party leases require extra care. For example, the rules restrict prepayments for more than 12 months of use. Certain leases of used personal property from a related party also require purchases of other qualifying property within a defined period. These rules can affect a business that rents equipment from an owner or affiliate.
Ask who owns the building, who leases it, and who owns the operating business. Similar names on the organization chart can hide separate legal relationships. Have counsel review market terms, renewal rights, purchase options, and related ownership. A lease that works for the business may still create an Opportunity Zone tax problem.
The 50% gross-income test concerns active business in the zone. It is not simply a rule that half the customers must live there. Regulations provide safe harbors based on services performed in the zone. These include hours worked and amounts paid for services. Another safe harbor considers zone property and management or operational functions, each necessary to generate at least half the business's gross income. A facts-and-circumstances route also exists. [1]
A business that develops software in the zone might sell to customers across the country. Those outside customers do not, by themselves, defeat the test. The company still needs records that support the chosen method. Remote staff, contractors, and shared services can complicate where work occurs and how it is counted.
At least 40% of intangible property must be used in active business in the zone. Intangible property can include rights that have no physical form. The regulations look at normal business use and whether that use in the zone helps generate gross income. Merely registering an address there is not enough. [1]
For an investor, the practical question is whether the manager can show how the company actually works. Payroll records, service agreements, operating reports, and asset records should tell a consistent story. A tax memo based on planned activities should be updated when those activities change.
The business must generally keep nonqualified financial property below 5% under a test based on average aggregate unadjusted bases. This is not simply 5% of market value or bank balances. Reasonable working capital and certain other items are excluded from the category, subject to the rules. [1]
The working-capital safe harbor can help a business fund a startup or development plan. It generally needs three things: a written plan for the money, a reasonable written spending schedule of no more than 31 months, and actual use that is substantially consistent with both. Funds must be held in permitted forms. Calling cash a reserve does not create a safe harbor.
Imagine a business receives money to buy land, build apartments, and pay startup costs. Its plan should identify those uses, the amounts, and the schedule. Later, the records should show what was spent and why. A vague promise to find a good project when markets improve is very different from a supported development plan.
The rules allow multiple applications of the safe harbor if each qualifies. Certain startups can receive up to 62 months through qualifying overlapping or sequential periods. This is conditional, not a standard 62-month grace period for every project. Later money must fit the required relationship to the original plan, and earlier money must have been spent as required. [1]
Waiting for government action on a complete application can affect the spending analysis. Certain federally declared disasters may allow added time. Neither rule excuses every permit delay, funding gap, contractor dispute, or management change. The manager should name the rule and show why it applies.
Operating and leasing real estate can be active business under these rules. Merely entering a triple-net lease, however, is not enough. In that type of lease, the tenant commonly pays taxes, insurance, and maintenance along with rent. The actual level of management and operations matters. [1]
The regulations give an example of an entire building leased to one tenant on a triple-net basis. The owner keeps staff there to address lease issues. That alone does not create the required active business. A separate example has meaningful management of two floors and a triple-net lease on another. The overall operations qualify in that example.
Do not read this as a blanket ban on every property with a net lease. Also do not assume one employee or a small office fixes the issue. Ask what the owner actually does, which duties remain with tenants, and why counsel believes the full operation meets the rule. Review the answer before you commit money.
The regulations exclude certain activities, including private or commercial golf courses, country clubs, massage parlors, hot tub facilities, suntan facilities, gambling facilities, and stores whose principal business is selling alcohol for consumption off the premises. They also address businesses that lease more than a de minimis amount of property to such activities. [1]
Small-amount exceptions have precise limits. They should not be treated as a casual permission slip. A shopping center owner must review the tenant mix as well as the owner's own activities. The alcohol category is also specific; it is not a statement that every restaurant serving a drink is barred. Counsel should classify the actual operation.
The program is moving into a new designation cycle. New zones take effect in 2027, while certain existing designations continue for a limited period. An old zone still appearing on a map does not automatically make every new purchase there eligible under the new rules. Dates and transition rules now matter even more. [4]
Notice 2026-40 describes rules Treasury and the IRS intend to propose for existing investments and businesses. It includes transition treatment for certain working-capital plans adopted by the end of 2026. The described conditions include receiving at least 10% of estimated plan capital and spending at least 5% by that deadline. Specified binding commitments can count toward the spending condition. [4]
For a $10 million plan, those percentages are $1 million received and $500,000 spent under the notice's terms. Meeting those two numbers alone is not enough. The plan and timing matter too. So do later purchases and other terms. This is announced transition treatment, not a claim that final regulations already resolve every fact pattern.
The notice also discusses property acquired to replace or modernize assets needed to continue an existing business. It distinguishes that work from expansion or a new business. Replacing apartment windows is not the same as buying an extra warehouse to grow operations. Have counsel identify the authority for the specific transaction before relying on a transition rule. [4]
Notice 2026-55 requests further comments and discusses additional rulemaking. Reporting and certification proposals were issued in September 2026. A proposal or request for comments should not be presented as a final rule. This guide reflects the sources reviewed on October 6, 2026; later transactions need a fresh check. [5]
Consider a company that starts with most of its staff and equipment in the zone. Two years later, it opens an office outside the zone and moves a key team there. That may be a sensible way to grow. It can also change the income and property tests. The original tax review needs to follow the business as it grows. [1]
The same issue arises with real estate. A new tenant might change the mix of activities in a building. A lease amendment might shift work from the owner to the tenant. A sale could leave the business holding a large cash balance. None of those facts should be ignored just because the first year went well.
The manager should review major changes before signing contracts. Ask for a simple process: identify the change, check the tests, get advice when needed, and keep the records. It is harder to repair a completed deal than to spot a problem in advance.
Also separate the business calendar from the investor's tax calendar. Cash at the project may be needed for work that has not yet been done. An investor may still face a tax bill before the project pays out cash. A long holding period does not mean taxes wait until the final sale. That gap should be part of the household's cash plan. [4]
I would want the business review to connect the tax case with the operating case. A project can pass a tax test and still lose money. It can also have a sound business plan but fail a tax condition. The review needs to consider both.
Under the current Form 8996 process, the fund certifies and reports its status; the underlying QOZB does not file that form merely because it is a zone business. That does not remove the need for business-level records or other returns. New reporting rules may change duties, so the manager should track final guidance and effective dates. [6]
Ask who is responsible when a test is missed. The fund's asset treatment and investor consequences can depend on the facts, timing, and available relief. A promise that someone will “pay a penalty” is not a full explanation. Investors should understand the possible effect on taxes, cash needs, and the investment itself.
No. The business must meet property, income, active-business, financial-property, and other rules. An address is only a starting point. How it is set up and run must meet the rules. [1]
No. A leased asset can count if it meets the rules. The lease must meet its own rules, including market terms and any related-party conditions. Leased assets also need to be valued properly for testing. [2]
No. The 70% test applies to tangible property by value. A separate gross-income test looks at active business in the zone, with safe harbors and a facts-and-circumstances method. Customer addresses alone do not decide it. [1]
Potentially. The working-capital safe harbor generally requires a written plan, a reasonable schedule of up to 31 months, and substantially consistent use. Extensions and multiple periods have conditions. Cash is not automatically exempt from testing. [1]
Merely entering a triple-net lease does not meet the active-business requirement. The full set of management and operating activities needs review. The regulations include both failing and qualifying real-estate examples. [1]
Not by itself. The investor-level tax election generally requires a qualifying investment in a QOF and compliance with separate eligibility and timing rules. A business that passes its tests does not replace those investor rules. [7]
No. Gain deferred under the pre-2027 investment rules is generally included by December 31, 2026, unless an earlier inclusion event applies. Potential benefits for later appreciation are separate. New five-year rules do not automatically extend that old deadline. [4]
No. It is a tax classification with conditions, not a rating of quality or safety. Construction costs, tenant demand, debt, fees, and management can still lead to losses. Review the economics alongside the tax plan.
