The Qualified Opportunity Zone program, created by the 2017 Tax Cuts and Jobs Act and administered through IRS regulations, is the federal government’s primary tax incentive for directing private capital investment into designated low-income census tracts. It has generated billions of dollars of real estate development activity in zones across the country, attracted a category of equity investor (capital gains investors) who would not otherwise invest in commercial real estate, and created a development financing structure with specific timing requirements and compliance obligations that practitioners who have not worked with the program before consistently underestimate.
Understanding how the QOZ program works, including its most commonly misunderstood structural requirements, is essential for developers considering OZ projects and for the construction managers, lenders, and advisors who work with them.
How the Tax Incentive Works
The QOZ program provides three tax benefits to investors who place capital gains in a Qualified Opportunity Fund (QOF) within 180 days of realizing the gain.
First, the investor defers recognition of the original capital gain until the earlier of the date they sell their QOF investment or December 31, 2026, whichever comes first. Under current law, the 2026 date has been extended in various legislative proposals, but investors should treat it as a binding deadline without confirmed extension.
Second, for investments held more than five years, the investor receives a step-up in basis on the original gain. For investments held more than seven years, a larger step-up applies. The basis step-up reduces the original gain that must be recognized at the 2026 deadline.
Third, and most importantly for development projects, if the QOF investment is held for at least ten years, any appreciation in the QOF investment itself is permanently excluded from federal income tax. This is the program’s most significant benefit: a development project that appreciates substantially over a ten-year hold generates tax-free appreciation for QOF investors, which enables QOF equity to accept lower current returns than conventional real estate equity because of the tax-free appreciation benefit.
The Substantial Improvement Requirement
The QOZ program’s most significant construction-specific requirement is the substantial improvement test. For a QOF to receive program benefits from an existing building (as opposed to new ground-up construction), the QOF must substantially improve the property, which the IRS defines as doubling the adjusted basis of the building within 30 months of acquisition.
For a development team buying an existing building for $2 million with an existing improvement value of $1 million, the substantial improvement test requires the QOF to invest at least $1 million in improvements within 30 months. This is a genuine capital investment requirement, not a nominal improvement, and it must be invested specifically in improvements to the existing building, not in land.
The 30-month timeline is unforgiving for complex projects with permitting challenges. A QOF that acquires a property in a market where permitting takes 12 to 18 months and construction takes 18 to 24 months does not have enough time within the 30-month window to complete substantial improvement from a standing start. Planning the acquisition timing, sometimes intentionally delaying closing until permits are further along, is an important structural consideration for QOZ projects in slow-permitting markets.
New ground-up construction on QOZ land avoids the substantial improvement requirement entirely, because the original use of the property has not yet been established. Many QOZ development programs therefore prefer ground-up construction or acquisitions where the land value significantly exceeds the improvement value.
Qualified Opportunity Zone Businesses and Their Requirements
QOF investments in real estate must be structured through a Qualified Opportunity Zone Business (QOZB), an entity that holds the real property and that meets specific requirements under the IRS regulations. The QOZB must conduct business in the qualified zone, meet income and asset tests that confirm it is operating in the zone, and comply with “sin business” exclusions that prevent QOF investment in golf courses, country clubs, massage parlors, hot tub facilities, suntan facilities, racetracks, gambling facilities, and liquor stores.
The 90% asset test, which requires that at least 90% of a QOF’s assets be qualified opportunity zone property, creates timing challenges during the development period when the project is consuming cash for construction but has not yet produced a completed building. Managing the 90% test during active construction requires attention to the QOF’s asset composition at each semi-annual testing date.
OZ Development in Innergy Integral’s Markets
Qualified Opportunity Zones are concentrated in low-income census tracts that often include transitional urban neighborhoods, areas that are adjacent to active development markets but that have historically lacked the investment that drives neighborhood revitalization. In Seattle and Tacoma, OZ-designated tracts include portions of the Central District, Rainier Valley, and South Tacoma that are within range of active transit service. In Dallas, OZ tracts include portions of South Dallas, West Dallas, and the southern suburbs that have historically underperformed despite proximity to the city’s active development corridors.
For developers considering OZ projects, the market-rate feasibility of the specific project in the specific location is the foundation of the investment decision, not the tax benefit structure. The QOZ program’s benefits are substantial, but they do not transform an infeasible project into a feasible one. A project that doesn’t generate adequate returns on a pre-tax basis will not be rescued by tax incentives that benefit only investors who have realized capital gains to defer.
Construction management on OZ projects involves the same disciplines as any commercial development, rigorous GC selection, active change order management, schedule accountability, plus specific attention to the 30-month substantial improvement timeline that creates a real schedule constraint for rehabilitation projects.
