Structuring Opportunity Zone Funds

Designs Qualified Opportunity Zone fund structures compliant with IRC §1400Z-2 and Treasury Regulations, covering entity formation, 90% asset test compliance, investment timelines, substantial improvement requirements, and tax deferral/exclusion mechanics.

When To Use

• Forming a new Qualified Opportunity Fund (QOF) or Qualified Opportunity Zone Business (QOZB)
• Evaluating whether a proposed investment qualifies for OZ tax benefits
• Structuring capital gains rollovers into a QOF within the 180-day window
• Analyzing whether a real estate project meets the substantial improvement test
• Designing fund terms (PPM, LP/LLC agreement) around OZ-specific holding period and compliance constraints
• Advising on exit timing to maximize basis step-up and gain exclusion benefits

Inputs To Gather

• Capital gains source: Type of gain (short-term, long-term, §1231), recognition event date, and 180-day deadline calculation
• Investor profile: Number of investors, tax status (individual, partnership, corporation, trust), state residency for state OZ conformity analysis
• Target investment: Asset class (real estate, operating business, mixed), geographic location (confirm census tract designation as a Qualified Opportunity Zone) [VERIFY census tract status — designations can expire or be updated]
• Entity structure preferences: Single-asset vs. multi-asset fund, LP vs. LLC, blocker entities for tax-exempt or foreign investors
• Project budget and timeline: Total project cost, acquisition cost of existing structures (for substantial improvement basis calculation), projected construction/renovation schedule
• Intended hold period: 5-year, 7-year, or 10-year horizon and desired tax benefit tier
• State OZ incentives: Whether the fund's state(s) offer conforming or additional OZ tax benefits [VERIFY — state conformity varies significantly]

Workflow

1. Confirm OZ Eligibility

   • Verify the target property/business is located in a designated Qualified Opportunity Zone census tract
   • Confirm the investor's capital gain qualifies as an "eligible gain" under §1400Z-2(a)
   • Calculate the 180-day investment deadline (note: for partnership gains, the 180-day window may start at partnership year-end or gain recognition date — investor elects) [VERIFY current IRS guidance on 180-day start date for pass-through entities]

2. Select Entity Structure

   • QOF must be organized as a corporation or partnership (including LLC taxed as either) and self-certify on Form 8996
   • Determine single-tier (QOF holds assets directly) vs. two-tier (QOF invests in a QOZB subsidiary) structure
   • Two-tier is typical for operating businesses; single-tier is common for direct real estate holds
   • Address blocker entity needs for tax-exempt investors (UBTI concerns) or foreign investors (FIRPTA, ECI)

3. Design Compliance Framework

   • 90% Asset Test: At least 90% of QOF assets must be Qualified Opportunity Zone Property, tested semi-annually (June 30 and December 31). Penalty for failure: amount of shortfall × federal short-term rate × underpayment penalty rate
   • Substantial Improvement Test (for existing buildings): QOF/QOZB must double the adjusted basis of the building (excluding land) within any 30-month period beginning after acquisition. Land value is excluded from the test basis
   • 70% Tangible Property Test (QOZB level): At least 70% of QOZB tangible property must be QOZP
   • Working Capital Safe Harbor: QOZB can hold working capital for up to 31 months if there is a written plan, schedule, and the capital is designated for OZ property acquisition, construction, or development [VERIFY — COVID extensions may have modified safe harbor timelines]

4. Map Tax Benefit Timeline

   • Deferral: Eligible capital gain invested in QOF is deferred until the earlier of (a) the date the QOF investment is sold or (b) December 31, 2026 [VERIFY — the 2026 inclusion date under current law]
   • Basis Step-Up (5 years): 10% basis increase in deferred gain after 5-year hold (effectively excludes 10% of deferred gain) — note: this benefit expired for most investors as of December 31, 2026 recognition date [VERIFY whether legislative extensions have been enacted]
   • Basis Step-Up (7 years): Additional 5% (total 15%) after 7-year hold — same expiration concern

Output

• QOF Structure Memorandum: Entity diagram, tier structure rationale, compliance framework, and tax benefit timeline
• 90% Asset Test Compliance Calendar: Semi-annual testing dates with asset valuation procedures and cure period deadlines
• Substantial Improvement Analysis (if applicable): Basis calculation, 30-month improvement schedule, budget allocation between land and building
• Investor Tax Benefit Summary: Table showing deferral amount, basis step-up milestones, and 10-year exclusion eligibility per investor class
• Risk and Compliance Matrix: Key compliance triggers, penalty calculations for asset test failures, and legislative risk factors

Quality Checks

• Confirm census tract designation is active and has not expired [VERIFY]
• Validate that 180-day deadlines are correctly calculated for each investor's specific gain recognition event
• Verify substantial improvement math excludes land basis and uses post-acquisition adjusted basis of improvements
• Ensure 90% asset test accounts for all QOF assets, including cash and working capital (apply safe harbor where documented)
• Cross-check that fund documents contain transfer restrictions sufficient to protect OZ holding periods
• Confirm state-level OZ conformity — many states decouple from federal OZ provisions or impose additional requirements [VERIFY per applicable state]
• Flag any investor whose 5-year or 7-year hold period cannot be achieved before the December 31, 2026 deferred gain recognition date [VERIFY current statutory deadline]
• Review for UBTI exposure if tax-exempt investors participate, and FIRPTA/ECI exposure for foreign investors
