Opportunity Zone 2.0: What Changed and the Dates for a 2026 Gain

What an opportunity zone is, and what Public Law 119-21 changed

A qualified opportunity zone (QOZ) is a census tract that is a “low-income community” and has been nominated by the state’s chief executive and designated by Treasury (26 U.S.C. 1400Z-1). A qualified opportunity fund (QOF) is a corporation or partnership that holds at least 90% of its assets in property in those zones. A taxpayer who sells property to an unrelated person can leave the gain out of income to the extent it is invested in a QOF within 180 days. Everything below is about what Public Law 119-21 changed in that machinery and what the IRS has said since. For the more than a thousand funds that already exist, how much they raised and what they disclose they pay brokers, see our Form D census of opportunity zone funds; we do not repeat it here.

Source: Public Law 119-21, section 70421 (139 Stat. 223-234) as published by the Government Publishing Office; 26 U.S.C. 1400Z-1 and 1400Z-2 as published by the Legal Information Institute; Rev. Proc. 2026-14 and Notice 2026-40 for the description of the earlier rules.

The Treasury press release of July 1, 2026 explains why the timing matters to governors: “Because new designations will occur only once every 10 years,” a state that does not nominate an eligible tract now has no second chance until the next round.

The new tax mechanics, with numbers

For amounts invested after December 31, 2026, the statute’s year of inclusion is the taxable year that includes the earlier of a sale or the fifth anniversary. The amount included is the lesser of the deferred gain or the investment’s fair market value on that date, minus basis. Basis starts at zero, then rises by 10% of the deferred gain at five years (30% in a qualified rural opportunity fund), and by the gain you recognize.

Our arithmetic from section 1400Z-2(b)(2) as amended: lesser of $500,000 and the fund value, minus 10% (or 30%) of $500,000. Not tax advice; partnership-level events and state rules can change the result.

Three things follow from the text. First, the tax comes due at year 5 whether or not the fund has paid out a dollar, as it does under the old December 31, 2026 rule. Second, the extra 5% step-up for a 7-year hold is gone for new money. Third, for the 10-year election the statute now gives a basis equal to fair market value on the sale date if you sell before year 30, and fair market value on the 30th anniversary otherwise; for this example that is February 1, 2037 and February 1, 2057 (our arithmetic). A qualified rural opportunity fund is one that holds at least 90% of its assets in property in zones made up entirely of rural areas, “rural area” meaning anywhere except a city or town of more than 50,000 inhabitants and the urbanized area next to it. The IRS’s own investor page, last reviewed December 23, 2025, still says gain is deferred “by December 31, 2026, whichever is earlier”; for money invested after that date, the statute above governs.

Timeline: the dates that matter for a gain realized in 2026

Sources: Public Law 119-21; IRS Rev. Proc. 2026-14 (2026-20 I.R.B. 910); IRS Notices 2026-40 (2026-28 I.R.B. 33) and 2026-55; Federal Register document 2026-18574; Treasury press release of July 1, 2026; IRS Opportunity Zones page and HUD Opportunity Zones Updates read October 9, 2026. Day counts are our arithmetic.

Two clarifications of dates that are often stated loosely. The new zones do not all start on one statutory date. The law says a zone’s designation begins on “the January 1 following the date on which such QOZ was certified and designated,” so a tract certified in 2026 starts January 1, 2027, and one certified later would start a year later. And the first determination date is July 1, 2026, but that is when nominations opened, not when zones took effect. The Idaho Business Review reported on October 2, 2026 that Treasury had certified Idaho’s 25 tracts, so certification is under way state by state; we found no national list from Treasury or the IRS.

Your 180-day window: the last day by recognition date

The IRS puts it in one line: “The first day of the 180-day period is the date the gain would be recognized for federal income tax purposes if you did not elect to defer the recognition of the gain.” The 180th day is therefore the recognition date plus 179 days.

Our arithmetic, counting the recognition date as day 1 per the IRS FAQ above; the IRS’s transition rule is Notice 2026-40, section 4.02(2). Partners, S corporation shareholders and beneficiaries of estates and non-grantor trusts can start their own 180 days on other dates (IRS FAQ Q23): for a calendar-year partnership that realizes a gain in 2026, the options include December 31, 2026 (180th day June 28, 2027) and the March 15, 2027 return due date (September 10, 2027).

What this means mechanically: a 2026 gain invested in a fund in, say, November 2026 falls under the old rule, so the deferred gain is included on the 2026 return anyway and only the 10-year election remains. The same gain invested in February 2027 falls under the five-year rule. That is the reading Notice 2026-40 confirms; which is better for a given person is a tax question we do not answer.

The zones: 8,764 now, 25,332 eligible, and where the official map is

We counted the CDFI Fund’s list of the 2018 designations and the appendix to Rev. Proc. 2026-14 by script (script and output in the dataset). The CDFI file lists 8,764 tracts, of which 8,566 are low-income communities and 198 are non-low-income contiguous tracts, a category the 2025 law repeals for new designations. The appendix lists 25,332 tracts eligible for nomination, 8,334 of them in rural areas, matching the revenue procedure. Applying the rule in Rev. Proc. 2026-14, section 2.02(3)(c) (25% of the state’s low-income tracts, “rounding the fractional quotient up to the next whole number,” and 25 tracts where a state has fewer than 100), the state caps add up to 6,544 (our arithmetic) against 8,764 today. Matching on the 11-digit tract number, at least 5,322 of the 2018 zones also appear on the eligible list (tract numbers differ between the 2010 and 2020 censuses in places, so treat that as a floor).

Source: CDFI Fund list “Designated Qualified Opportunity Zones” (updated December 14, 2018) and the appendix to IRS Rev. Proc. 2026-14, counted by script; maximum nominations are our arithmetic. All 56 jurisdictions are in the dataset. OpportunityZones.com reports, citing Treasury correspondence, that Treasury later added 128 tracts to the eligible list; we could not confirm that in a primary document.

Which tracts are zones is a lookup, not something to eyeball from a table, and we do not build our own map. The official places: the HUD map of designated zones (the 2018 designations; the IRS page links to it), the CDFI Fund’s Community Investment Mapping System (where Treasury says poverty and income data for eligible tracts can be viewed), and Treasury’s Qualified Opportunity Zones data page, which links the eligible-tract list. The CDFI Fund’s own spreadsheet says its list “is not the official list”; the official 2018 list is IRS Notice 2018-48, as amplified by Notice 2019-42. The 2027 designations will need the same treatment once published.

Pitfalls the guidance points to

• A 2018 zone is not automatically a 2027 zone, and the date of purchase matters. Notice 2026-40, section 5.01, says property acquired by a QOF or business after December 31, 2026 “cannot be QOZBP unless (i) the property is acquired for use in a QOZ that is designated after July 4, 2025, or (ii) one of the exceptions in section 5.01(2) and (3) of this notice applies.” The exceptions are a written working-capital plan adopted by December 31, 2026 (with at least 10% of the planned working capital received and at least 5% spent by that date) and replacement of existing property in the ordinary course, not expansion. The 2018 zones themselves stay designated through December 31, 2028.
• The 90% test is measured twice a year, on the last day of the first 6-month period and the last day of the fund’s taxable year. A fund below 90% pays a monthly penalty on the shortfall at the section 6621(a)(2) underpayment rate unless it shows reasonable cause. Cash received from investors can be excluded from the test for up to 6 months if it is held in cash, cash equivalents or debt of 18 months or less (Form 8996 instructions).
• Business-level tests. A zone business must have at least 70% by value of its owned or leased tangible property in qualifying zone property, and the working-capital safe harbor requires the money to be spent “within 31 months” under a written schedule (both as described in Notice 2026-40). Existing property bought by a fund counts only if its original use in the zone starts with the fund or the fund substantially improves it: additions to basis above the adjusted basis within 30 months, or 50% of it in a zone made up entirely of a rural area.
• Related parties. Gain from a sale to a related person is not eligible, and “related” for this purpose uses a 20% ownership test instead of 50% (section 1400Z-2(e)(2)). If only part of what you put into the fund is eligible gain, the investment is split into two, and only the eligible part gets the benefits.
• Paperwork. The investor files Form 8997 every year with the tax return and reports the deferral on Form 8949; the fund self-certifies on Form 8996. The new section 6039K return adds a penalty of $500 per day, capped at $10,000 per return ($50,000 for a fund with more than $10 million of gross assets), and $2,500 per day for intentional disregard, with indexing after 2025. The proposed regulations would require investor statements by March 1 after a disposition.
• Fees. The Form D shows only sales commissions and related-person payments; management fees and promotes are in the offering documents. What funds disclosed is in our Form D census. On how a large gain is taxed in the first place, see capital gains tax on real estate and the alternative of a 1031 exchange; for K-1 timing on partnership funds, real estate crowdfunding taxes.

What you can do with this

This is a list of questions the public record lets you answer yourself, not advice on whether to invest.

• Write down your recognition date and add 179 days. If it falls on or after January 1, 2027, the question of old versus new rules depends on when you actually invest.
• If you are already in a fund, ask the sponsor what value it will report at December 31, 2026, because the amount included is capped by it. Our Form D census covers that date.
• If you are looking at a new fund, ask for the census tract number of each property and check it against the lists above, ask whether the property is bought before or after January 1, 2027, and ask whether the fund is a qualified rural opportunity fund and on what test.
• Put the fifth anniversary on the calendar. For new money the tax on the deferred gain comes due in the year of the fifth anniversary even if the fund is still held.
• Watch the open items: the designation list (expected before January 1, 2027), the proposed reporting regulations (comments due October 16, 2026) and Notice 2026-55 (comments due November 23, 2026).
