Opportunity Zones Made Permanent: What OBBBA Changed and the New 5-Year Deferral Clock

Qualified Opportunity Zones are an economic development tool enacted in the Tax Cuts and Jobs Act of 2017. The IRS describes the program plainly: "Opportunity Zones are an economic development tool that allows people to invest in distressed areas in the United States."^[1] The incentive sits in Internal Revenue Code Sections 1400Z-1 and 1400Z-2, and a taxpayer accesses it by investing eligible capital gain in a Qualified Opportunity Fund rather than paying the tax in the year of the sale.

The original statute carried a hard sunset: deferred gain had to be included by December 31, 2026, and no new deferral election was allowed after that date. The One, Big, Beautiful Bill Act of 2025 kept the program alive and reshaped it. Notice 2026-40 announces the Treasury and IRS position: the agencies "intend to issue proposed regulations regarding qualified opportunity zones (QOZs) under §§ 1400Z-1 and 1400Z-2 of the Internal Revenue Code (Code)1, as amended by § 70421 of Public Law 119-21, 139 Stat. 72 (July 4, 2025), commonly known as the One, Big, Beautiful Bill Act (OBBBA)".^[5] For investors weighing a QOF in 2026 or 2027, see the firm's advisory solutions work on the timing and entity-choice calls that drive whether the deferral is worth taking.

The deferral is available to any taxpayer with eligible gain who timely invests a corresponding amount in a QOF. The IRS defines the universe of eligible gain narrowly in the deferral mechanics: "You can defer tax on eligible gains you invest in a Qualified Opportunity Fund until you have an inclusion event or by December 31, 2026, whichever is earlier."^[11] Ordinary gain, including depreciation recapture that is characterized as ordinary, is not eligible. The investment must be made within the statutory window: "To defer tax on an eligible gain, you must invest in a Qualified Opportunity Fund in exchange for equity interest (not debt interest) within 180 days of realizing the gain."^[2]

Two mechanics catch new investors off guard. First, debt is not a qualifying investment: a loan to a QOF, or a QOF that uses the money to repay a loan to the investor, does not start the clock. Second, basis in the fund begins at zero. The IRS states it this way: "When you make an election to defer the gain, the basis in the Qualified Opportunity Fund investment becomes zero."^[3] Any later sale of the QOF interest before the 10 year mark starts from that zero basis, so the deferred gain comes back dollar for dollar unless the hold reaches the step-up thresholds. For investors reporting the deferral on their individual return, this interacts with every other capital-gain election for the year, which is where individual tax return preparation matters.

The fund is the vehicle, not the investor. The IRS defines it as "an investment vehicle that files either a partnership or corporate federal income tax return and is organized for the purpose of investing in QOZ property."^[10] A fund becomes a QOF by self-certifying each year: "To become a QOF, an eligible corporation or partnership elects to self-certify by annually filing Form 8996 with its federal income tax return."^[10] A limited liability company works if it is taxed as a partnership or corporation.

There is a hard asset test underneath. Notice 2026-40 states that a QOF "holds at least 90 percent of its assets in QOZP as measured on the dates described in § 1400Z-2(d)(1)(A) and (B) (90-percent investment standard)."^[12] Below the fund, a QOZ business must earn "at least 50 percent of its gross income from business activities within a QOZ",^[10] and tangible property only counts if its original use in the zone starts with the fund or the business, or the property is substantially improved. Those tests are what separates a real QOZ deal from a label on a syndication, and they are the piece that most often goes wrong at audit. Where a QOF is a partnership or corporation the sponsor files, the fund-level return is work the firm covers under business tax return preparation.

This is the biggest OBBBA change. Under the old rule the inclusion year was the one that included December 31, 2026, regardless of when the money went into the fund. Notice 2026-40 describes the new mechanism: "In addition, § 70421(c)(2) of the OBBBA modified prior § 1400Z-2(b) in multiple ways, including by changing the taxable year of inclusion in prior § 1400Z-2(b)(1)(B) from that which includes December 31, 2026, to that which includes the date that is 5 years after the date the qualifying investment was made."^[6]

The 5 year clock reaches two things. First, the deferred gain is included in income in the earliest of three dates: a sale or exchange of the qualifying investment, an inclusion event other than a sale, or 5 years after the investment date. Second, the basis step up now rides on that same clock: "Under § 1400Z-2(b)(2)(B), if a qualifying investment is held for at least five years, a taxpayer's basis in the qualifying investment increases by 10 percent (or 30 percent, in the case of any investment in a qualified rural opportunity fund, as defined in § 1400Z-2(b)(2)(C))."^[6] Under the prior rules a 5 year hold earned 10 percent and a 7 year hold added another 5 percent, and that stepped build is gone for post-2026 money. The 7 year step up only matters to investors who were already in a QOF under the prior regime.

The deferral election is reported on Form 8949. The IRS explains it on the Invest in a Qualified Opportunity Fund page: "Once you have done this, you can elect the deferral on Form 8949, Sales and Other Dispositions of Capital Assets, for the taxable year in which the gain would be recognized if you didn't defer it."^[13] The second filing is Form 8997: "You must file annually Form 8997, Initial and Annual Statement of Qualified Opportunity Fund (QOF) Investments with your timely filed federal tax return (including extensions)."^[4] Form 8997 is the annual tracking statement; it is filed every year the investor holds a qualifying investment, not only in the year of the election.

The fund-level reporting runs on Form 8996. A fund that misses the 90-percent investment standard owes an under-investment penalty figured on that form; a fund that fails to self-certify at all is not a QOF. For investors, the practical consequence of fund-level failures is that gain the investor thought was deferred may not be deferred at all, which is a reason to see the QOF's Form 8996 and 8997 history before signing a subscription. The reporting load is why QOF investments show up frequently on the engagements the firm handles for its real estate + property management tax help clients.

The 10 year hold has always been the headline incentive. The IRS states the mechanics: "If you hold your investment in the Qualified Opportunity Fund for at least 10 years, you may be able to permanently exclude gain resulting from a qualifying investment when it is sold or exchanged."^[3] The exclusion is done through a basis-step-up election on sale or exchange, so appreciation on the fund interest from the date of investment through sale is removed from taxable gain, leaving only the previously deferred eligible gain (which has already been included on the 5 year date under the new rules).

OBBBA added a hard ceiling. Notice 2026-40 explains the new provision as "providing that, in the case of any qualifying investment held by the taxpayer for at least 10 years and with respect to which the taxpayer makes an election under that subsection, the basis of such qualifying investment equals its fair market value on the earlier of (i) the date such qualifying investment is sold or exchanged, or (ii) the date that is 30 years after the date of that qualifying investment."^[7] In practice, an investor who holds past the 30 year mark fixes the step up value as of year 30, which is a meaningful planning constraint for sponsors building long hold structures around trust and estate transfers.

An inclusion event is any event that reduces or terminates the qualifying investment: "An inclusion event, in general, is an event that reduces or terminates your qualifying investment in a QOF."^[10] Several of the common ones are inside the investor's own planning. Giving a qualifying investment away is one: a gift of the QOF interest to a child, to a non-grantor trust, or in a divorce transfer is an inclusion event, so the deferred gain becomes due in that year. A transfer to a revocable grantor trust is not, because the investor is still treated as the owner of the trust for federal income tax purposes.

Two other events frequently blindside investors. A QOF liquidation before the inclusion year ends the deferral; the deferred gain is reported in that year on Form 8949, with the change reflected on Form 8997. A distribution from a QOF partnership with a fair market value in excess of the partner's basis in the qualifying investment is also an inclusion event, limited to the excess. The 10 year basis step-up election is not available for any portion of the investment that is no longer a qualifying investment, which is why planners track inclusion events every year rather than only at exit.

Every QOZ designation runs for a defined period, after which the tract is no longer a QOZ for new acquisitions. Notice 2026-40 states the expiration dates for the currently designated zones: "(i) December 31, 2027, for QOZs deemed certified and designated in Puerto Rico under prior § 1400Z-1(b)(3), and (ii) December 31, 2028, for all other QOZs."^[9] That is the end of designation, not the end of QOF investments inside the zone: a fund that bought property in a designated QOZ before the expiration can continue to treat the tract as a QOZ for ongoing substantial-use testing, subject to the transitional rules in Notice 2026-40.

For new designations under OBBBA, the clock starts fresh. The notice explains: "A QOZ designation period under § 1400Z-1(e)(1) begins on the applicable start date and ends on the day before the date that is 10 years after the applicable start date."^[8] For LICs certified in 2026, the applicable start date is January 1, 2027: "Therefore, for every LIC certified and designated by the Secretary as a QOZ under § 1400Z-1(b) during 2026, the QOZ designation period begins on January 1, 2027, and ends on December 31, 2036."^[14]

The failure modes cluster at the edges of the mechanics rather than in the center. The 180 day window gets missed when the investor assumes it runs from receipt of a K-1 instead of from the date the pass-through sold the asset; the pass-through rule gives partners and S corporation shareholders three alternative start dates, and picking the wrong one is a common defect. The eligibility test fails when ordinary gain, including depreciation recapture characterized as ordinary, is treated as if it were capital. The equity rule fails when the investor's money goes in as a loan to the fund rather than through a subscribed interest.

The cost of a failed election is the full deferred gain plus any underpayment interest, included in the year the election is disallowed rather than the year the taxpayer intended. The 10 year fair market value step up is also lost on the portion of the investment that was not qualifying from the start, so the back-end benefit disappears along with the deferral. For investors who are already in a QOF and want a second opinion on whether the deferral still holds, that review sits inside the firm's advisory solutions work, next to the firm's real estate investor tax guide overview for property investors.
