Rural Opportunity Zones in 2026: Living Between OZ 1.0 and OZ 2.0

Updated August 17, 2026 to reflect Notice 2026-40.

In 2026 the Opportunity Zone program sits across two regimes. A current-year capital gain invested now is governed by the original program (OZ 1.0). The permanent program enacted by the One Big Beautiful Bill Act (OZ 2.0) governs investments made on or after January 1, 2027. One OZ 2.0 feature is already in effect and easy to miss: for property in a rural OZ tract, the substantial improvement threshold is reduced from 100% to 50% of basis. This piece addresses where the two regimes overlap in 2026, what the rural carve-out does and does not do, and what changes when OZ 2.0 goes live on January 1, 2027.

Scope. This piece addresses federal Opportunity Zone structuring and the 2026-to-2027 transition. It does not address state OZ conformity, the securities treatment of a fund raise, or the facts of any particular investor’s gain.

1. The 2026 picture

OZ 1.0 is winding down but not dead, and OZ 2.0 is enacted but not yet live for new investment. 2026 is the overlap year, with one rural-specific feature of OZ 2.0 already in effect. A current-year capital gain invested today is governed by OZ 1.0, the rural label of the underlying tract does not change deferral timing, and deferred gain is recognized on the earlier of disposition or December 31, 2026. The rolling five-year deferral, the 10% basis step-up, and the enhanced 30% step-up for Qualified Rural Opportunity Funds (QROFs) apply only to investments made after December 31, 2026. The one OZ 2.0 provision already in effect is the reduced 50% substantial improvement threshold for property in rural OZ 1.0 tracts, confirmed in Notice 2025-50 (issued September 30, 2025) and effective for the underlying statutory change as of July 4, 2025.

2. Where OZ 1.0 stands

The original Opportunity Zone regime, enacted in the Tax Cuts and Jobs Act of 2017 and codified at IRC § 1400Z-2, lets an investor defer eligible capital gain by investing it within 180 days in a Qualified Opportunity Fund. Two features of the original regime drive the 2026 dynamic.

• The hard inclusion date. Section 1400Z-2(b)(1)(B) requires recognition of all deferred gain on the earlier of disposition of the QOF interest or December 31, 2026. The OBBBA did not move that date.
• The 2028 sunset of the existing designations. The 8,764 OZ 1.0 census tracts designated in the 2018 Treasury process remain designated through December 31, 2028. Capital in a 1.0 QOF can continue to be deployed at the QOZB level into qualifying property in those tracts, subject to the transition rules Notice 2026-40 later supplied for property acquired after December 31, 2026, which I cover in the Notice 2026-40 article.

For any 2026 gain, there is no way to extend deferral past the December 31, 2026 inclusion date. The remaining 1.0 levers, the 10-year exclusion on back-end appreciation, the 50% substantial improvement threshold in rural tracts, and project-level QOZB structuring, are real but do not push the inclusion date.

3. The rural carve-out already in effect

The OBBBA, signed July 4, 2025, contains one rural-specific provision that operates retroactively. For property in a rural OZ 1.0 census tract, the substantial improvement test under § 1400Z-2(d)(2)(D)(ii) is reduced from 100% of adjusted basis to 50% of adjusted basis. The IRS implemented the change in Notice 2025-50, issued September 30, 2025, which identified the 3,309 qualifying rural tracts and conformed the Form 8996 instructions. The underlying statutory threshold change is effective as of July 4, 2025.

Two points are easy to miss.

• It is a project-economics feature, not a deferral feature. Reducing the capital expenditure required to treat property as substantially improved matters at the QOZB level, because it lowers the basis a sponsor must add to a building to qualify for OZ treatment. It does not change when the investor recognizes deferred gain. A 2026 investment in a rural tract still reaches the December 31, 2026 inclusion date.
• It applies to existing OZ 1.0 rural tracts, not to a new class of OZ 2.0 tracts. The 3,309 tracts identified under Notice 2025-50 are tracts already designated in the 2018 process that also meet the rural definition. They sunset on December 31, 2028 with the rest of the 1.0 designations unless they are also nominated and approved as OZ 2.0 tracts.

4. What goes live on January 1, 2027

The OZ 2.0 framework introduces a different deferral mechanic and a separate, higher-benefit rural fund concept. The headline features apply to investments made on or after January 1, 2027.

• Rolling five-year deferral. Eligible gain invested in a 2.0 QOF is deferred for five years from the date of investment, replacing the fixed December 31, 2026 inclusion of the 1.0 regime. § 1400Z-2(b), as amended.
• 10% basis step-up at year five for ordinary 2.0 QOF investments, and 30% at year five for Qualified Rural Opportunity Funds, a 2.0-specific vehicle that invests substantially all of its assets in property in rural 2.0 tracts. § 1400Z-2(b)(2)(B), (C).
• 10-year exclusion on appreciation preserved, on the same general terms as OZ 1.0.
• New QOF and QOZB reporting and penalty regime under new §§ 6039K, 6039L, and 6726.

The designation cycle is new and decennial. Under Rev. Proc. 2026-14, the federal nomination window opens July 1, 2026 and runs 90 days, closing September 28, 2026, with a 30-day extension available on request that pushes the deadline to October 28, 2026. Each state’s nomination cap is 25% of eligible tracts. State intake ran ahead of the federal window.

• Texas. The community nomination deadline was June 26, 2026, and nominations have closed. The Texas Economic Development and Tourism Office reported more than 1,200 proposed tracts from more than 175 economic development organizations and county judges across 114 counties, and intends to submit its selections to Treasury no later than August 3, 2026. Texas may nominate up to 605 of its 2,420 eligible tracts.
• Missouri. The Missouri Department of Economic Development ran its OZ 2.0 intake from April 7 to May 17, 2026. That window has closed, and Missouri is expected to nominate approximately 131 tracts for designation effective January 1, 2027.

Old-zone designations expire December 31, 2027 (Puerto Rico) and December 31, 2028 (everywhere else), and OZ 2.0 investment is fully operational January 1, 2027.

6. The 2026 structuring question

For an investor with a 2026 capital gain, the question is whether to invest in a 1.0 QOF now or wait for OZ 2.0. The answer turns on the 180-day investment window and, for gain already deferred, on Notice 2026-40.

A 2026 gain, generally. Whether it can reach OZ 2.0 depends on timing. Notice 2026-40 § 4.02(2) provides that eligible gain realized before December 31, 2026 may be invested in a QOF on or after January 1, 2027 and receive OZ 2.0 treatment, provided the investment is timely, meaning within the 180-day window. A gain realized late enough in 2026 that its 180-day window runs into 2027 can therefore be placed in a 2027 QOF for the rolling five-year deferral, the step-up, and the 10-year exclusion. A gain whose 180-day window closes in 2026 cannot reach 2.0, and the realistic options are: invest in a 1.0 QOF and absorb the December 31, 2026 inclusion in exchange for the 10-year exclusion on back-end appreciation; invest in a 1.0 QOF in a rural tract for the 50% substantial improvement threshold, with the same deferral outcome; or use other planning, including loss harvesting against the inclusion.

Gain already deferred in a 1.0 QOF. Rolling gain that is already deferred, including the gain deemed included on December 31, 2026, into a 2027 QOF is not an open question after Notice 2026-40. Section 4 draws a bright line. If the investor still holds the original qualifying investment, the deferral election remains in effect and the deemed-included gain cannot be re-deferred under § 1400Z-2(a)(2). Notice 2026-40 § 4.01(2). If the investor no longer holds it, typically because the gain arose from selling the QOF interest, reinvestment of the inclusion-event gain is available regardless of what caused the inclusion. Notice 2026-40 § 4.03. This resolves what earlier commentary treated as unsettled, and it is covered further in the Notice 2026-40 article.

A QOF that accepts both 1.0 and 2.0 investments. Mixed-fund treatment for a single QOF taking 1.0 capital in 2026 and 2.0 capital after January 1, 2027 remains unsettled. Two questions are open: whether the 90% asset test and the working capital safe harbor apply uniformly across both vintages within one fund, and whether basis adjustments, inclusion events, and the 10-year exclusion run separately on each vintage of investor capital. Until Treasury addresses the integration questions, the conservative approach is separate funds by vintage.

7. Practical takeaways

• Whether a 2026 gain can reach OZ 2.0 turns on the 180-day window. A gain whose window runs into 2027 can go into a 2027 QOF; a gain whose window closes in 2026 cannot, and its deferral ends December 31, 2026.
• Gain already deferred in a 1.0 QOF, including the deemed December 31, 2026 inclusion, generally cannot be rolled into a 2.0 QOF while the investor still holds the original investment. Reinvestment is available only where the investor no longer holds it.
• Rural OZ 1.0 deals are more attractive in 2026 than before July 4, 2025 because of the 50% substantial improvement threshold. Sponsors with capital chasing rural product should run the math against the 100% threshold they previously underwrote.
• The OZ 2.0 designation process runs through the second half of 2026. Several state intake windows, including Texas and Missouri, have already closed. The federal nomination deadline is September 28, 2026, extendable to October 28.
• Mixed 1.0 and 2.0 funds are a structuring trap. Until Treasury issues guidance, separate funds for separate vintages are the conservative call.
• The 1.0 tract sunset is December 31, 2028, not 2026. A 2026 1.0 QOF investment can keep deploying capital into 1.0 QOZBs through the sunset, and Notice 2026-40 extends zone treatment for the substantial-use element through December 31, 2047 for property acquired before expiration or under its transition safe harbors.
