Qualified Opportunity Zone Business: Four Tests and Safe Harbor

To meet Qualified Opportunity Zone Business requirements, an entity has to pass four ongoing federal tests at the same time: at least 70 percent of its tangible property must qualify as Opportunity Zone business property, at least 50 percent of its gross income must come from active business conducted inside the zone, at least 40 percent of its intangible property must be used in that active conduct, and no more than 5 percent of its assets can sit in nonqualified financial property. It also has to avoid a short list of categorically excluded business types, and the property it counts toward the 70 percent test has to meet its own acquisition and improvement rules. Miss any one of these on a testing date, and the parent Qualified Opportunity Fund starts owing penalties.

The Four Ongoing Tests

Every QOZB test runs continuously. There is no one-time certification. The business either meets the thresholds when the IRS or the parent fund looks, or it doesn’t.

70 Percent of Tangible Property Must Qualify

The statute says “substantially all” of the tangible property the business owns or leases must be Opportunity Zone business property. Treasury regulations set that at 70 percent, measured by comparing the value of qualified property located in the zone against the total value of all tangible property the business holds.¹

Two additional “substantially all” tests apply asset by asset. At least 70 percent of the use of each qualifying asset must occur within the zone, and that use condition must be met during at least 90 percent of the business’s holding period. Multiplied together, this means at least 63 percent of any given asset’s total use over the ownership period has to take place inside the zone.²

Valuation generally uses unadjusted cost basis. Leased property counts, valued as the present value of lease payments calculated on the lease start date, using the discount rate in Treasury Regulation Section 1.1400Z2(d)-1(b)(4)(iii)(B).³ That inclusion of leases gives service businesses that rent their space a workable path to compliance.

50 Percent of Gross Income From Active Business in the Zone

At least half of the business’s total gross income each taxable year has to come from the active conduct of business inside the Opportunity Zone.² The IRS looks at where services are performed, where the tangible property generating the income sits, and where management and operations occur. A zone address paired with a workforce that operates elsewhere will not hold up.

40 Percent of Intangible Property Used in the Zone

At least 40 percent of the business’s intangible property, including patents, copyrights, and proprietary software, must be used in the active conduct of business within the zone. The threshold is lower than the tangible test, but the point is the same: intellectual property parked at a zone address and licensed to operations elsewhere doesn’t count.

No More Than 5 Percent Nonqualified Financial Property

A QOZB cannot hold more than 5 percent of the average of its total unadjusted asset bases in nonqualified financial property. That category covers stocks, partnership interests, options, futures contracts, and debt instruments.¹ The ceiling exists to push money into operations rather than portfolios. Reasonable working capital held in cash or short-term instruments with maturities of 18 months or less is excluded, but only if it fits inside the working capital safe harbor.

The Working Capital Safe Harbor

A new QOZB has a real problem the moment it accepts a large infusion from its parent fund: that cash would immediately push it past the 5 percent financial property ceiling. The working capital safe harbor gives the business up to 31 months to deploy the money without being penalized for holding it.

To qualify, the business needs a written plan identifying how the funds will be spent, plus a schedule showing the working capital will go toward acquiring, constructing, or substantially improving tangible property within the 31-month window. Vague plans without dollar amounts, timelines, or identified projects will not hold up in an audit.

A business can stack overlapping safe harbors as it receives successive rounds of capital. Each infusion starts its own 31-month clock and needs its own plan. This is sometimes called the 62-month safe harbor, though no single period is actually extended. Businesses located in federally declared disaster areas can receive an additional 24 months on top of the standard period, for a maximum of 86 months.⁴

Businesses That Can Never Qualify

Some business types are barred from qualifying regardless of where they operate or how well they meet the asset tests. The statute borrows its list from the rules governing qualified redevelopment bonds:⁵

Golf courses and country clubs, private or commercial.
Massage parlors, hot tub facilities, and suntan facilities.
Racetracks and other gambling facilities, including casinos and off-track betting.
Liquor stores whose primary business is selling alcohol for off-premises consumption. Restaurants and breweries where patrons drink on-site are not swept in by this rule.

The liquor store exclusion turns on whether packaged off-site alcohol sales are the principal activity. If more than half the revenue or floor space goes to that, the business is out. None of these exclusions can be overridden by strong performance on the other tests.

How Property Itself Has to Qualify

The 70 percent test only counts tangible property that is itself “qualified.” That means the property was purchased after December 31, 2017, from an unrelated party, and it meets either the original use standard or the substantial improvement standard.²

“Unrelated” here uses a 20 percent common-ownership threshold rather than the usual 50 percent. You cannot buy qualifying property from anyone who shares 20 percent or more common ownership with the purchasing entity.¹

Original Use

Property meets the original use standard when the QOZB is the first entity to place it in service within the zone for a purpose requiring depreciation. New construction and newly purchased equipment typically qualify. Vacant property also qualifies as original use if it was vacant for at least three uninterrupted years after the census tract was designated as an Opportunity Zone, or if it was already vacant at least one year before designation and remained vacant through the date of purchase.² The vacancy rule opens up abandoned commercial and industrial buildings that would otherwise require substantial improvement.

Substantial Improvement

When property was previously used in the zone by someone else and the vacancy exception doesn’t apply, the buyer has to substantially improve it. During any 30-month period beginning after acquisition, additions to the property’s basis must exceed the adjusted basis of the property at the start of that period.² Buy a building with an adjusted basis of $400,000, and you need to spend more than $400,000 on improvements inside 30 months.

Land is excluded from this calculation. The substantial improvement test applies only to buildings and structures, and land inside a zone never needs to be separately improved to count as qualified.⁶ A developer paying $1 million for a parcel with $600,000 in land value and $400,000 in building basis only has to beat $400,000 in improvement spending. That distinction makes rehabilitation of older buildings far more workable than the purchase price alone would suggest.

Real Estate: The Triple-Net Lease Trap

Real estate is the most common QOZB use case, and the regulations have a rule that catches passive owners. Owning and operating rental real estate, including leasing, counts as an active trade or business. But entering a triple-net lease, where the tenant handles taxes, insurance, and maintenance, does not. A business whose only activity is collecting rent under a triple-net lease is not conducting an active trade or business for QOZB purposes.

Real estate QOZBs need to take a substantive role: handling maintenance, making capital improvement decisions, managing tenant relationships, and performing landlord functions beyond depositing checks. The distinction bites hardest on the 50 percent gross income test, since rent from a purely triple-net-leased building may not count as income from active business conduct inside the zone.

What Happens If the Business Falls Out of Compliance

A QOZB that misses a requirement gets a one-time, six-month cure period. During those six months, the parent QOF is treated as still meeting its 90 percent asset test, and the business can acquire additional qualified property, sell nonqualifying assets, or otherwise return to compliance. A QOF can only use this cure period once for each QOZB it holds. A second failure has no regulatory safety net.

If the cure doesn’t happen inside six months, the fund’s holdings in that entity stop counting as qualified Opportunity Zone property. The QOF then owes a penalty equal to the shortfall multiplied by the federal underpayment rate (the short-term applicable federal rate plus three percentage points).² The bigger risk for investors is losing the deferral and the long-term appreciation exclusion that made the investment worth making.

What the QOZB Owes Its Parent Fund

QOZBs do not file their own certification form. Form 8996 is filed by the parent QOF alone, to self-certify its status and report compliance with the 90 percent investment standard.⁷ The QOZB’s job is to give the fund enough information to demonstrate that the business meets every requirement under Section 1400Z-2(d)(3). Failure to provide it can trigger fund-level penalties.⁸

Practically, that means keeping thorough records of tangible property values and locations, gross income broken out by source, intangible property usage, financial asset holdings, and any working capital safe harbor plans. Those records feed the fund’s Form 8996 and are what the IRS examines in an audit. Weak bookkeeping at the business level becomes a compliance failure at the fund level.
