OZ 1.0 vs. OZ 2.0: What Changes for Fund Managers After January 1, 2027

The Opportunity Zone program is now permanent law. But the rules that govern a fund depend entirely on when its investors committed capital — and the differences are significant. Fund managers operating across both regimes face a dual compliance reality that will persist for years.

A Program Made Permanent

When Congress created the Opportunity Zone program in 2017, it built in a sunset. The program was temporary by design, with investment eligible only through December 31, 2026, and deferred gains ultimately recognized on that date. That sunset is now gone.

On July 4, 2025, President Trump signed the One Big Beautiful Bill Act (OBBBA), making the Opportunity Zone program a permanent feature of the Internal Revenue Code. The OZ program will now run indefinitely, with new zone designations issued on a rolling ten-year basis — the first OZ 2.0 designations taking effect January 1, 2027.

But permanence does not mean uniformity. The rules that govern a given investor's tax treatment depend on when they committed capital to a QOF. Investments made on or before December 31, 2026 are governed by the original TCJA rules (OZ 1.0). Investments made on or after January 1, 2027 are governed by the OBBBA rules (OZ 2.0). Fund managers operating QOFs that span both periods — or that are fundraising now for 2027 capital — are operating under two distinct compliance regimes simultaneously.

The Core Differences at a Glance

Gain Deferral

Under OZ 1.0, the gain deferral period was fixed. All deferred gains recognized under the original program must be included in income by December 31, 2026 — regardless of when the investment was made, and regardless of whether the fund has exited any positions.

Under OZ 2.0, the deferral is rolling. Each qualifying investment receives a five-year deferral from its own investment date. An investor who commits capital on March 1, 2027 defers recognition until March 1, 2032. An investor who commits on October 15, 2028 defers until October 15, 2033. There is no program-wide sunset date — the deferral period moves with each investor's entry point.

Basis Step-Up

OZ 1.0 provided a two-tiered basis step-up. Investors who held their QOF interest for at least five years received a 10% step-up on the deferred gain; those who held for seven years received an additional 5%, for a total of 15%. To earn the seven-year benefit, investment had to occur by December 31, 2019.

OZ 2.0 simplifies the structure. A 10% basis step-up remains available after a five-year holding period. The additional 5% at seven years has been eliminated. For standard QOFs, the benefit profile is slightly less generous than early OZ 1.0 — though offset by the rolling deferral structure, which eliminates the pressure of a fixed recognition date.

For investments in Qualified Rural Opportunity Funds (QROFs) — a new category introduced by the OBBBA — the five-year basis step-up is 30%, triple the standard rate.

The 10-Year Appreciation Exclusion

Perhaps the most valuable feature of both OZ 1.0 and OZ 2.0 is unchanged: investors who hold their QOF or QROF investment for at least ten years can exit with no tax on the fund's appreciation — the basis is stepped up to fair market value at the time of sale.

Under OZ 1.0, this exclusion was available for dispositions through December 31, 2047. The OBBBA replaces the 2047 sunset with a rolling 30-year cap: for investments sold or exchanged before the 30th anniversary of the investment date, the basis steps up to FMV at disposition. For investments held 30 years or more, the basis is frozen at FMV on the 30th anniversary. This effectively extends the program's benefit horizon indefinitely, eliminating the 'forced exit' concern that existed under OZ 1.0.

Zone Designations and the Map Redraws

The original 8,764 OZ census tracts designated in 2018 remain active through December 31, 2028 — not December 31, 2026 as some have assumed. This creates a two-year overlap period (2027-2028) during which both OZ 1.0 and OZ 2.0 zone designations are simultaneously valid.

The new OZ 2.0 zones, effective January 1, 2027, will be drawn using tighter eligibility criteria. The median family income qualification threshold has been reduced from 80% to 70% of the area or statewide median. Census tracts qualifying on poverty rate grounds are disqualified if their median family income exceeds 125% of the benchmark. Contiguous tract designations have been eliminated entirely. Current estimates project a 25% reduction in the total number of qualified census tracts nationwide — from roughly 8,764 to approximately 6,500.

Importantly, the most attractive current OZ tracts — those already experiencing redevelopment and rising values — are among the most likely to lose their designation under the new, tighter criteria. The 2026 window is genuinely the last opportunity to invest in those communities under the OZ incentive.

The New Qualified Rural Opportunity Fund

One of the most significant structural additions in OZ 2.0 is the creation of Qualified Rural Opportunity Funds (QROFs). A QROF must invest at least 90% of its assets in qualified opportunity zone property located entirely within rural areas — defined as any area outside a city or town with a population exceeding 50,000, and not in an urbanized area contiguous to such a city.

QROFs offer two enhanced benefits relative to standard QOFs: a 30% basis step-up at five years (versus 10%) and a substantially improved threshold set at 50% — meaning a QROF needs to increase the basis of acquired property by only 50% to meet the 'substantial improvement' standard, versus 100% for standard QOF investments.

Reporting: The Biggest Operational Change

One area where OZ 1.0 and OZ 2.0 converge — and where the operational stakes are highest — is the new mandatory reporting framework. The OBBBA introduced Code Sections 6039K and 6039L, establishing annual reporting requirements that apply to all QOFs, regardless of when they were established.

Under §6039K, QOFs must file detailed annual information returns disclosing asset values, NAICS codes, property details, residential unit counts, employment figures, and investment breakdowns — including information about each QOZB in which the fund is invested. Under §6039L, QOZBs are now independently required to provide annual written statements to their QOF investors containing the data needed for §6039K compliance. Prior to the OBBBA, QOZBs had no reporting obligations whatsoever.

These requirements are effective for tax years beginning after July 4, 2025. For calendar-year funds, they apply beginning with the 2026 tax year. Failure to comply carries penalties of $500 per day up to $10,000 per return for standard funds, and up to $50,000 for QOFs with gross assets exceeding $10 million. Intentional disregard triggers penalties up to $250,000 for large funds.

What This Means for Fund Managers Today

Most QOF managers currently operating are running OZ 1.0 funds — and their immediate compliance priority is the December 31, 2026 gain recognition event. But managers who are also fundraising for 2027 investments, or who operate multi-investor structures likely to attract post-2026 capital, need to understand that those investors will be in a different legal regime from day one.

The dual-period reality is not temporary. An investor who commits in 2019 and a new investor who commits in 2028 can be in the same fund but governed by entirely different rules on deferral, step-up, and reporting. Fund agreements, investor communications, and compliance systems need to account for this distinction explicitly.

OZX is built for both regimes. Whether your fund is managing OZ 1.0 obligations through the 2026 recognition event or building compliance infrastructure for post-2027 capital, OZX provides the tools to manage both. Learn more at ozxpro.com.
