Investors following the next generation of Qualified Opportunity Zones have a new IRS document to read, but not because it settles the rules.

Notice 2026-55 is a request for additional comments on issues under section 1400Z-2. Treasury and the IRS are asking taxpayers, funds and other stakeholders how future guidance should address several parts of the Opportunity Zone regime after the 2025 statutory changes. Written comments are requested by Nov. 23, 2026.

The notice covers more than distributions and leverage

For investors, the IRS asks whether inclusion-event rules need clarification for debt-financed distributions or losses and whether the existing disguised-sale rules should change. It also asks how the 10-year election should work when an investment reaches the new 30-year valuation date.

For funds and operating businesses, the open questions include changes to a working-capital safe-harbor plan, the effect of working-capital spending on the 70% tangible-property test, and the treatment of inventory. A separate group of questions asks whether and how Opportunity Zone incentives could coordinate with housing programs and single-family construction.

None of those questions creates a new safe harbor or calculation method. They identify subjects on which Treasury and the IRS may later propose guidance.

Tribal communities and rural-fund benefits are distinct issues

The amended statute already provides a 30% basis increase after five years for a qualifying investment in a qualified rural opportunity fund, compared with 10% for other qualifying investments made after 2026. Notice 2026-55 repeats that background; it does not create the benefit.

The notice's community-specific request is different. Treasury and the IRS ask how the incentive has been used in Tribal and Alaska Native communities and what clarifications could encourage investment in Qualified Opportunity Zones on Tribal and Alaska Native Claims Settlement Act lands.

Keep open questions out of the current-law column

For an existing or contemplated Qualified Opportunity Fund investment, separate four layers in the workpapers: the amended statute, existing final regulations, published transition guidance, and unresolved questions in Notice 2026-55. A model involving leverage or distributions should show the current-law result separately from any result that assumes favorable future guidance.

The same discipline applies to working-capital plans and the 30-year valuation rule. The notice is evidence that Treasury and the IRS are considering those issues, not authority for a preferred treatment.

How to comment — and what to watch next

Comments should reference Notice 2026-55 and are requested by Nov. 23, 2026. Electronic comments can be submitted through Regulations.gov under docket IRS-2026-1156; submitted comments will be made public. Later comments may still be considered if doing so does not delay guidance.

The next document to watch is proposed or other guidance that follows this comment process. Until then, investors and funds should apply the statute and guidance already in force rather than treating a question in the notice as a new rule.
