01 / The investment structure
A common starting point is a QOF investing cash for equity in a project LLC that operates the qualifying business. Direct fund ownership is another route with different compliance consequences.
Also at the project level: developer cash or property · ordinary equity · construction debt
The QOF’s 90% asset test does not mean it must own 90% of the project. Mixed capital is possible, but investor-level benefits attach to qualifying investments—not automatically to all the equity, fees, or sponsor promote.
Entities, ownership, and cash distributions
A single-property QOF can have multiple investors, and more than one QOF can invest in a project. Entity classification, certification, project equity issuance, and offering documents need review. An investment in another QOF is not simply qualifying property for the investing QOF.
Tax allocations and cash distributions are different. Operating agreements, financing restrictions, and the waterfall determine cash flows. A pass-through structure does not make all income tax-free.

02 / Location and acquisition dates
Verify the exact tract, official designation, effective period, and acquisition date. A map showing eligibility or nomination is not proof of final designation.
For the new cycle, zones certified in 2026 take effect January 1, 2027. Post-2026 acquisition rules need separate review; do not assume an old designation or a property already owned is sufficient.
Transition cases and rural status
Notice 2026-40 contains limited transition treatment for specified existing plans and other circumstances. It is not blanket permission for new purchases in old-only zones. Review the actual acquisition mechanics against the applicable start date.
A wholly rural zone may have a different improvement threshold. Enhanced investor benefits through a qualified rural opportunity fund require a separate fund-level analysis; a rural address alone is not enough.

03 / Four separate clocks
| Stage | What to confirm |
|---|---|
| Investor → QOF | Generally 180 calendar days from the applicable starting event. Confirm the rule for the specific taxpayer and gain. |
| QOF → project | Fund testing dates, effective month, qualifying assets, and any permitted recent-contribution exclusion. |
| Project spending | A conditional 31-month working-capital plan from receipt, with written uses, schedule, and consistent execution. |
| Rehabilitation | A separate 30-month substantial-improvement measurement period when relying on that route. |
Why there is no universal second 180-day deadline
A calendar-year QOF commonly tests on June 30 and December 31, subject to first-year rules. Certain recent contributions held in prescribed liquid assets can be excluded from a particular test. The six-month lookback and custody conditions must be applied to the actual facts.
Do not treat that exclusion as an automatic six-month deployment allowance or a promise that cash can sit for a year. Use execution buffers and have the fund accountant establish the calendar.
31 months, later tranches, and construction delays
The working-capital safe harbor requires written designation of funds, a reasonable spending schedule, and substantially consistent use. Buying near the end of the period does not restart the original cash’s clock.
Some sequential or overlapping funding plans can provide additional protection, including a conditional 62-month startup period. Each application has requirements; the first contribution cannot simply be parked for 62 months. Government-delay and disaster relief require separate analysis.
A gain in 2026 and an investment in 2027
A qualifying gain realized in late 2026 can potentially support a timely 2027 QOF investment under the new regime. Funding the QOF in December 2026 is not converted into a 2027 investment by a later property purchase.
For regular-way exchange-traded stock, review the trade-date rule. Pass-through and installment gains can have different starting dates. The intake deliberately asks for an adviser-confirmed deadline instead of generating one from a generic sale date.

04 / What property can qualify?
Analyze the land, existing building, new construction, and other improvements separately. Original use and substantial improvement are different qualification routes.
| Route | Initial question |
|---|---|
| Unrelated purchase | Do timing, purchase, use, and development requirements work? |
| Contributed property | Which contributed assets remain nonqualifying, and can new construction qualify separately? |
| Sale by the developer | Do related-party and attribution rules permit qualifying purchase treatment? |
Already-owned land or buildings
A contribution can earn negotiated economic equity without satisfying the qualifying-purchase rule. Keep contribution value, tax basis, OZ test value, and eligible gain invested through a QOF separate.
New construction on contributed land can potentially qualify separately. The contributed land itself generally does not satisfy the purchase requirement. Apply current acquisition dates alongside older IRS explanations.
Related-party sales need an ownership analysis
The OZ rules substitute 20% for 50% in specified related-party tests. That is not a universal rule that any 20% interest fails, or that a nominal ownership reduction solves attribution. Review family, indirect, capital/profits, and common-ownership relationships. A new LLC is not automatically unrelated.
Substantial improvement: the benchmark and the period
In the general nonrural case, qualifying additions during a 30-month period must exceed the building’s starting adjusted basis. The threshold for qualifying wholly rural zones is more than 50%. Land is excluded from the building benchmark. Exactly 100% or 50%, respectively, is not enough.
Illustration: a $3M purchase allocated $2M to land and $1M to the building, with $1M starting building basis, requires additions exceeding $1M under the general rule. The purchase price itself is not improvement spending.
Have the accountant classify budget lines. New rear construction does not automatically count as rehabilitation of a front building; aggregation provisions depend on their own conditions.

05 / The 90% and 70% tests
The fund’s assets
Generally the average qualifying-asset percentage across applicable testing dates, with permitted methods and exclusions.
The project’s tangible property
Qualifying tangible property divided by total tangible property, using the applicable valuation rules.
The project ratio uses property value under a permitted method. It is not based on unit counts, square footage, investor ownership, or the percentage of construction funded with gains. A negotiated equity credit is not automatically the test value.
A passing ratio is only one requirement
Construction-period protection needs its own analysis. A stabilized ratio does not establish compliance throughout development. The business must also satisfy applicable income, activity, intangible-property, financial-asset, and prohibited-business requirements.
Merely entering into a triple-net lease does not establish active conduct of a business. Review actual management and operations with the advisers.

06 / Example: a duplex plus a fourplex
Hypothetical—not Monte Vista or an offering. A developer contributes a parcel with an existing duplex, and the project builds a separate rear fourplex without subdivision. Assume the land and duplex are nonqualifying and the new fourplex qualifies.
These are assumed values under a permitted OZ valuation method, not estimates of price or construction cost. Assume no other tangible property, and all other requirements, for this arithmetic only.
| Asset-test illustration | Scenario A | Scenario B |
|---|---|---|
| Contributed land + duplex (nonqualifying) | $600,000 | $1,200,000 |
| New fourplex (qualifying) | $1,600,000 | $1,600,000 |
| Total tangible property | $2,200,000 | $2,800,000 |
| Qualifying ratio | 72.7% | 57.1% |
| 70% threshold alone | Met | Not met |
Four of six units being new is not the calculation. Debt does not simply reduce the nonqualifying value. Other property and construction-period rules can change the analysis.

07 / Example: a mixed capital stack
Illustration only. The source of funds and the asset tests answer different questions.
| Source | Amount |
|---|---|
| Construction debt | $6M |
| QOF cash equity | $3M |
| Ordinary developer cash equity | $1M |
| Total | $10M |
This does not require 70% or 90% of the capital stack to be eligible gains. Borrowing does not become qualifying investor equity, and ordinary developer equity or a service-based promote does not automatically receive investor-level benefits. Review leverage, guarantees, offering requirements, and each investor’s interest separately.

08 / Benefits, liquidity, and the exit
For qualifying QOF investments made after 2026, original-gain recognition is generally at five years or an earlier inclusion event. A qualifying five-year hold brings a 10% basis increase, with separate enhanced rural-fund treatment. Plan the tax payment even if the project retains its cash.
After at least ten years, an eligible election can provide the appreciation benefit. The post-2026 rule limits the valuation reset at the 30-year anniversary for later dispositions. The original gain is not erased.
Hold periods, refinancing, and state taxes
Each investor’s qualifying investment has its own holding period. Construction completion does not start that clock. Ten years is a benefit threshold, not a universal legal lockup.
Refinance proceeds are borrowed funds; distributions need basis, debt-allocation, inclusion-event, and other tax review. A property sale and an investor-interest sale are not interchangeable in every respect. Model the actual exit.
California does not conform to federal OZ deferral and exclusion. Review state consequences for the project and each investor separately.

09 / Plans, annual work, and source notes
A written working-capital plan is a contemporaneous spending record, not a ten-year holding plan submitted for IRS preapproval. Retain receipts, uses, the budget, milestones, spending records, explanations of deviations, and any claimed relief.
Assign owners for certification, testing dates, investor elections, annual tax and information reporting, property records, and review before distributions or major changes. Use the forms and instructions applicable to the reporting year.
