The Internal Revenue Service proposed rules Thursday for implementing new statutory requirements for opportunity funds to file information returns to improve the agency's ability to administer and enforce the federal opportunity zone program's tax benefits.

The proposed regulations arrive more than seven years after the Tax Cuts and Jobs Act created the opportunity-zone incentive, which allows investors to defer and reduce capital-gains taxes by placing proceeds into designated low-income census tracts through qualified opportunity funds. The program has attracted billions in family-office and institutional capital, but disclosure requirements have been limited.

The new information-return mandate stems from statutory changes Congress enacted to give the IRS better tools to track compliance. The agency has said publicly that it lacks comprehensive data on how much capital has flowed into opportunity zones, which funds are active, and whether investments meet the program's qualifying-use tests.

The proposed rules do not alter the substantive tax benefits available under the opportunity-zone statute. They address only the reporting obligations that funds must satisfy going forward. The IRS released the proposed regulations in its weekly bulletin on Friday.

Opportunity-zone funds have faced questions about whether certain property types and lease structures satisfy the law's requirement that investments serve a qualifying business purpose in the designated zones. The IRS has issued prior guidance on some of those questions but has not brought a wave of enforcement actions.

Disclosure rules that look burdensome at enactment tend to harden into enforcement levers once the agency has a full data set, family office advisor Jaf Glazer has noted.

The information-return proposal follows other recent IRS regulatory activity. On the same day, the Treasury Department proposed regulations clarifying changes to foreign tax credits under the 2025 federal budget bill. That rule would reduce the range of expenses companies must allocate to overseas affiliates when calculating the credits.

The Deployment Angle

Family Office Real Estate Daily Desk · our analysis, not the source's

Family offices holding opportunity-zone fund stakes through co-GP arrangements or as direct limited partners should expect administrators to request additional documentation to support the new filings. Principals who committed capital in the program's early years, when guidance was sparse, face the highest audit risk if their funds took aggressive positions on what counts as a qualifying investment or a qualifying business.

The information-return requirement does not change the economics of existing deals, but it does change the IRS's ability to cross-check fund-level claims against investor-level tax filings. Offices that have not yet completed a formal legal review of their opportunity-zone holdings should commission one now, before the final rule takes effect and while there is still time to cure technical defects through restructuring or fund amendment.

For new commitments, this development argues for platforms that have taken conservative underwriting positions on qualifying use and have built robust tax-reporting infrastructure. Co-GP structures carry an added advantage: direct governance rights let the family office ensure the fund stays current on compliance even if the reporting burden increases. Avoid funds that rely on single-asset holding companies or that show weak documentation of the original basis step-up and deferral calculations.
