Why It Matters

Congress has made the Opportunity Zone tax incentive permanent even though most states remain unable to determine whether billions of dollars in investments are delivering measurable economic benefits to the low-income communities the program was designed to help.

A recent GAO report published on Aug. 24 examining the Opportunity Zone tax incentive found significant uncertainty about whether the program is delivering on its goal of spurring economic development in low-income communities. The findings raise questions about the effectiveness of a tax incentive that Congress has now made permanent even as evidence of its real-world impact remains unclear.

Congress created the Opportunity Zone tax incentive to spur investment in economically distressed communities. GAO surveyed all states and U.S. territories and found that states were mostly unsure about the effects of Opportunity Zone investment on economic outcomes. About 20% of states cited increased job creation and housing as effects of Opportunity Zone investment.

The uncertainty matters because Congress made the Opportunity Zone incentive permanent in 2025 while adding new reporting requirements intended to provide more information about investments and their potential economic effects. Qualified Opportunity Funds held more than $108 billion in assets as of the end of 2024.

The Big Picture

GAO surveyed all states and U.S. territories regarding the Opportunity Zone tax incentive and interviewed selected state officials and subject-matter specialists from five organizations. GAO also analyzed Census data, reviewed a nongeneralizable sample of 16 Qualified Opportunity Funds and conducted site visits involving investments from seven selected funds.

States reported a significant information gap. Most were unsure about the effects of Opportunity Zone investment on outcomes in their states even as the program has operated for several years and Qualified Opportunity Funds have accumulated more than $108 billion in assets.

The Opportunity Zone incentive is primarily funding real estate development, according to stakeholders interviewed by GAO. Zones that received investment tended to be in urban areas with access to infrastructure and community support. Aurora, Colorado, is highlighted in the GAO report as an example of Opportunity Zone investment involving an apartment building under construction.

The concentration in real estate does not by itself establish whether the incentive is producing broader economic benefits in designated communities, an issue underscored by states' uncertainty about the program's effects.

Broader Context

Congress changed the program's structure through the One Big Beautiful Bill Act. The law made the Opportunity Zone incentive permanent and changed eligibility criteria for Zone designation, resulting in fewer eligible census tracts for future selection. Stakeholders told GAO that the changes could allow the incentive to better target economically distressed areas.

The law also created additional incentives for investment in newly defined rural Zones and added new reporting requirements for funds and the Treasury Department. GAO found that the reporting requirements could allow the government and public to better understand Opportunity Zone investments and their potential economic effects.

The changes are intended to address some challenges identified with the original incentive. However, stakeholders remained uncertain about how much the additional tax benefits for rural Zones would increase investment in those areas.

The Bottom Line

Making the Opportunity Zone incentive permanent means the program will continue with new Zone designations rather than ending under the original structure. Congress made that decision while evidence about the original program's effects on communities remained incomplete.

For policymakers, GAO's findings highlight an unresolved question. States largely cannot determine what effects Opportunity Zone investments have produced, while the federal government is only now implementing additional reporting requirements intended to provide greater insight into investment characteristics and potential economic effects.

The report also raises broader questions about how Congress evaluates tax expenditures. The Opportunity Zone incentive operates through the tax code rather than direct federal spending, providing tax benefits to investors who direct capital through Qualified Opportunity Funds into designated communities.

For investors and developers, permanence provides greater long-term certainty about the program. But GAO's findings show that stakeholders still have limited information about whether investments are translating into outcomes such as additional jobs and housing.

GAO's investigation underscores a central tension in the Opportunity Zone program. Congress has made the incentive permanent and revised it in hopes of improving its effectiveness, while the effects of the original incentive remain mostly unknown.
