The Program Is Permanent — but the Map Is Not
The 2025 One Big Beautiful Bill Act (OBBBA) did two things that matter to anyone deploying capital in an Opportunity Zone. First, it made the program permanent. Second — and this is the part that is moving fast right now — it replaced the one-time 2018 map with a decennial redesignation: a fresh set of zones every ten years, chosen by governors from a Treasury-published list of eligible tracts.
The first redesignation is happening this summer. If you sponsor OZ deals, run an Impact Fund, or advise investors who do, the tract you are counting on may not be a zone in eighteen months — and a tract that is not a zone today may become one. This is a live map, and the window to influence it closes in weeks, not years.
What Treasury Actually Published
On April 6, 2026, the Treasury Department and the IRS released Revenue Procedure 2026-14, the operational rulebook for the redesignation. Its headline numbers:
- 25,332 eligible census tracts were identified nationwide — the universe from which the new zones will be chosen.
- Each governor may nominate up to 25% of the eligible tracts in their state.
- Treasury is expected to certify the new designations by the end of 2026, with the zones taking effect January 1, 2027.
Governors may nominate up to 25 percent of the low-income community census tracts in the state that are eligible for designation as Qualified Opportunity Zones. — Framework of the OZ 2.0 nomination process under Rev. Proc. 2026-14
The Deadline That Is Actually Close
The nomination clock is a 90-day window that opened July 1, 2026. That puts the base deadline at roughly September 28, 2026, with a 30-day extension available on request — an outer limit near October 28, 2026. States are already moving: several governors’ offices opened public nomination portals within days of the window opening, inviting local governments, developers, and community organizations to submit tracts for consideration.
Translation for sponsors and Impact Funds: the case for including — or keeping — a tract on the new map is being made in your state right now. If a corridor central to your pipeline is at risk of falling off, the time to document its case to your state OZ office is this quarter.

Why Some of Today’s Zones Will Disappear
The redesignation is not a simple re-stamp of the old map. OBBBA tightened the eligibility criteria, which will push some currently-designated tracts out of the program entirely:
- The income bar dropped. A qualifying “low-income community” now generally needs median family income at or below 70% of the area or statewide median — down from 80% under the original program — or a poverty rate of at least 20% with median family income at or below 125% of the area median.
- The contiguous-tract rule is gone. The original program let governors designate certain tracts adjacent to low-income communities even if the adjacent tract did not itself qualify. OBBBA repealed that provision. Deals sited in those “contiguous” tracts should not assume the location carries forward.
The practical effect is a smaller, more sharply targeted map. For an Impact Fund whose thesis rests on a specific set of neighborhoods, that is both a risk (a tract you rely on drops off) and an opportunity (a genuinely distressed tract you have been eyeing finally qualifies). Either way, you cannot manage it without checking the new eligibility list against your pipeline.
The Timing Fork Every Deal Now Faces
Because the new zones do not take effect until January 1, 2027, there is a transition window that changes how you sequence a deal:
- Investments made on or before December 31, 2026 generally rely on the existing (“OZ 1.0”) map and rules that remain in force through year-end.
- Investments made on or after January 1, 2027 look to the new OZ 2.0 designations — with the rolling five-year deferral, the enhanced rural benefits, and the new reporting regime that came with them.
For a property sited in a tract that is designated today and expected to survive the redesignation, the calendar is a genuine strategic lever. For a property in a tract that may not carry forward, the answer is different again. This is exactly the kind of question to put to your tax advisor before you sign — the wrong month can change which regime governs the entire hold.

A Practical Checklist for the Next 90 Days
- Map your pipeline against the eligible-tract list. Confirm which of your target sites appear on the Rev. Proc. 2026-14 eligible universe — and which currently-designated sites are not on it.
- Engage your state OZ office. Governors are choosing from a much larger eligible pool than they can designate. A documented case — jobs, housing units, community benefit — for a tract you care about can influence whether it makes the 25%.
- Decide the timing of any near-term deployment with your advisor, knowing the OZ 1.0/2.0 fork lands on December 31, 2026.
- Line up the depreciation side early. Whatever zone you land in, the economics of the hold turn on how much of your basis is short-life property — and inside an OZ, that acceleration is uniquely durable.
Where Cost Segregation Fits
The redesignation decides where you can invest. A cost segregation study decides how efficient the investment is once you do. Inside an Opportunity Zone held ten years or more, the 10-year basis step-up excludes the gain at exit — including the depreciation you accelerated during the hold — which turns cost segregation from a timing benefit into a permanent one. And on value-add deals, the same component-level analysis that supports your depreciation schedule also supports the land-versus-building allocation behind the substantial-improvement test. We covered that pairing in depth in Cost Segregation + Opportunity Zones 2.0.
The Bottom Line
Opportunity Zones are permanent, but the specific zones are not — and the first redesignation is being decided this quarter. Treasury has named the eligible tracts, governors have until late September (or late October with an extension) to nominate, and the new map governs everything from January 1, 2027. Sponsors and Impact Funds that wait for the certified map to be published will have missed the only window in which they could shape it. Check your pipeline against the eligible list now, make your case to your state, and coordinate the timing and the tax positions with your advisor.
