What changed
The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, permanently extended the Qualified Opportunity Zone (QOZ) program and established rolling 10-year designation cycles, replacing the original fixed tracts designated under the 2017 Tax Cuts and Jobs Act. New zone designations take effect January 1, 2027 — but that shift created a gap for existing projects.
The IRS addressed that gap in Notice 2026-40, issued June 18, 2026. According to law-firm and advisory-firm summaries of the notice from Baker Tilly, Shipman & Goodwin, and the National Law Review, the core rule is that property located in an original QOZ 1.0 tract that is acquired after December 31, 2026 generally does not qualify as Qualified Opportunity Zone Business Property (QOZBP) under the OBBBA’s revised statutory definitions. The reason: original QOZ tracts lack an “applicable start date” under the new post-OBBBA framework, so the general statute cannot reach them.
Notice 2026-40 does provide transition relief for active development projects. Per Shipman & Goodwin’s summary (shipmangoodwin.com), a Qualified Opportunity Zone Business (QOZB) that has a documented working capital safe harbor plan in place before December 31, 2026 and deploys capital consistent with that plan before year-end may continue to have newly acquired property treated as QOZBP. A narrower exception also applies to routine replacement or modernization of existing property in the ordinary course of an ongoing business.
Why it matters to investors
For most individual QOF investors, the most immediate tax event is the gain-inclusion rule: gain originally deferred by investing in a QOF before January 1, 2027 must be included in income on the 2026 federal return, regardless of Notice 2026-40. That has always been the rule for original QOZ investments and is unchanged.
What Notice 2026-40 affects is the ongoing status of the fund and its underlying investments. A QOF must hold at least 90 percent of its assets in qualified opportunity zone property, and the businesses it holds must hold at least 70 percent of their tangible property as QOZBP. If assets acquired after December 31, 2026 in a QOZ 1.0 tract stop qualifying, those percentage tests can fall short — threatening the fund’s status and the 10-year gain exclusion that investors are counting on.
Notice 2026-40 clarifies that a QOF can still receive capital after 2026; the restriction is on whether property purchased with that capital qualifies. According to QOF sponsor Urban Catalyst, investors need to distinguish carefully between the gain-deferral deadline and the ongoing property-qualification rules when evaluating existing positions.

What to do before December 31, 2026
Confirm your fund’s zone status. Ask the fund manager whether the tracts where the fund holds or plans to acquire property are original 2017 QOZ 1.0 tracts, are being re-nominated under the OBBBA’s new state nomination cycle, or will qualify as QOZ 2.0 tracts effective January 1, 2027. Property in a newly designated 2027 tract is subject to a different set of rules.
Verify working capital plans. If the fund’s underlying QOZB has an active development pipeline extending past year-end, confirm that a written working capital safe harbor plan consistent with Notice 2026-40 is documented and that required capital-deployment milestones are met before December 31, 2026. The precise thresholds for plan funding and deployment are set out in the notice itself and should be verified with a tax professional before the fund relies on this exception.
Budget for the 2026 deferred-gain inclusion. The deferred gain retains its original character (capital gain) and is taxed at 2026 rates. Use the capital gains calculator to estimate the federal bill. The potential exclusion of post-investment appreciation after a 10-year hold is a separate benefit that depends on the fund maintaining its status.
The IRS stated in Notice 2026-40 that forthcoming proposed regulations will include broader safe harbors allowing QOZ 1.0 businesses and property to continue qualifying for certain purposes through 2047. Per the National Law Review’s analysis (natlawreview.com), those regulations have not yet been finalized. Investors should not rely on anticipated future guidance to satisfy current-year compliance obligations.
How Opportunity Zone tax benefits were designed to work
The Opportunity Zone program, created by the 2017 Tax Cuts and Jobs Act and codified at Internal Revenue Code §1400Z-2, offers investors three distinct federal tax benefits in exchange for rolling eligible capital gains into a Qualified Opportunity Fund (QOF) within 180 days of realizing the gain. Understanding all three helps explain why the December 31, 2026 date matters so much.
First is deferral: tax on the invested gain is postponed until the earlier of the date the QOF investment is sold or December 31, 2026. For nearly every investor still holding an original QOZ 1.0 position, that deferral period now ends with the 2026 tax year — which is why the deferred gain lands on the 2026 return. Second, the original law offered a basis step-up of 10 percent for a five-year hold and an additional 5 percent for a seven-year hold, but because the deferral always ended in 2026, those step-ups were only available to investors who contributed in 2019 or earlier; investors who bought in later generally receive no step-up on the deferred gain. Third, and most valuable, is the 10-year exclusion: an investor who holds the QOF interest for at least 10 years may elect to increase basis to fair market value on the date of sale, permanently eliminating federal tax on appreciation that accrued inside the fund.
The OBBBA’s permanent extension reshapes the first two benefits for investments made under the new post-2026 regime, but it does not retroactively revive expired step-ups for QOZ 1.0 money. The 10-year exclusion remains the reason most investors stay in their funds — and the reason Notice 2026-40’s property-qualification rules matter, because that exclusion depends on the fund continuing to meet its asset tests.
A worked example: two separate deadlines, two separate events
Consider an investor who realized a $500,000 long-term capital gain from selling appreciated stock in 2024 and, within 180 days, rolled the full $500,000 of gain into a Qualified Opportunity Fund. Because the investment was made after 2021, no five- or seven-year basis step-up is available. On the investor’s 2026 federal return, the entire $500,000 of previously deferred gain must be recognized. At a top combined rate of 23.8 percent (20 percent long-term capital gains plus the 3.8 percent net investment income tax), that produces roughly $119,000 of federal tax — due with the 2026 return even though no cash came out of the fund. The investor’s basis in the QOF interest then increases by the $500,000 recognized.
Now fast-forward. Suppose the fund’s underlying real estate project succeeds and the investor’s interest is worth $800,000 when sold in 2035, more than 10 years after the contribution. The investor elects the basis step-up to fair market value, and the $300,000 of appreciation is excluded from federal income entirely. The example shows the two events the IRS keeps separate: the 2026 inclusion of the original deferred gain is mandatory and unavoidable, while the 10-year exclusion of new appreciation is the payoff — but only if the fund keeps qualifying. These figures are illustrative; your actual rate depends on your bracket, filing status, and state. Use the capital gains tax calculator to model your own numbers.
The IRS forms a QOF investment requires
Three IRS forms carry a QOF investment through its life. The fund itself files Form 8996 each year to certify its status and report whether it met the 90 percent asset test on each semi-annual testing date; a fund that fails the test owes a monthly penalty. As an investor, you make the initial deferral election and report the eventual inclusion on Form 8949, attached to Schedule D. Every year you hold the investment, you also file Form 8997, the Initial and Annual Statement of Qualified Opportunity Fund Investments, listing your beginning and ending QOF holdings and any current-year deferrals or dispositions.
Form 8997 is easy to overlook, but it is not optional. The IRS uses it to track deferred gain, and failing to file it can be treated as evidence that an inclusion event occurred — potentially accelerating the very gain you are trying to defer. For the 2026 return, Form 8949 is where the deferred gain is pulled back into income, and Form 8997 should reflect the end of the deferral. Because the character and amount must tie out across all three forms, the year of inclusion is a year to have a tax professional prepare the return.
State conformity: not every state follows the federal rules
Federal Opportunity Zone benefits do not automatically carry over to your state return. Most states that impose an income tax conform to the federal treatment, so the deferral, step-ups, and 10-year exclusion flow through. But several states decouple. California, notably, does not conform to the federal Opportunity Zone provisions — a California resident who defers a gain federally still owes California tax on that gain in the year it is realized, with no deferral and no 10-year exclusion for state purposes. Other states have adopted partial conformity or their own in-state zone incentives.
The practical consequence is that an investor in a non-conforming state can face a state tax bill on a timeline that has nothing to do with the federal 2026 deadline, and may owe state tax on fund appreciation that is federally excluded after 10 years. Before assuming an Opportunity Zone investment is tax-advantaged in your state, confirm your state’s conformity status; the answer can materially change the after-tax return.
Common mistakes QOF investors make
Investing the whole sale proceeds instead of just the gain. Unlike a 1031 exchange, a QOF investment only requires you to reinvest the gain, not the entire proceeds, and the gain can come from any asset — stock, a business, or real estate — not just real property. Over-investing does not increase the deferred amount and can create a non-qualifying portion of the investment.
Missing the 180-day window. The clock generally starts on the date the gain would otherwise be recognized. Partnership and other pass-through gains have special rules that can extend the window, but the default deadline is firm, and a late investment simply does not qualify.
Confusing the two deadlines. As Notice 2026-40 underscores, the 2026 gain-inclusion deadline and the ongoing property-qualification rules are different things. Recognizing the deferred gain in 2026 does not end your investment or forfeit the 10-year exclusion.
Forgetting the annual Form 8997 and assuming all gain is tax-free after 10 years. The 10-year exclusion applies to appreciation in the QOF interest itself; it does not erase the original deferred gain, which is taxed in 2026, and it does not shelter ordinary income or any depreciation recapture the fund generates and passes through along the way.
Planning around the 2026 inclusion
Set aside cash for the 2026 tax now. Because the deferred gain is included whether or not the fund distributes anything, investors who already spent or reinvested their original proceeds can face a liability with no matching cash. Review your projected 2026 bill with the capital gains tax calculator and consider increasing estimated tax payments to avoid an underpayment penalty; the inclusion can push you into a higher bracket or trigger the net investment income tax.
Coordinate with other deferral tools. Opportunity Zones and 1031 exchanges both defer gain, but they are not interchangeable: a 1031 exchange is limited to like-kind real property and defers the entire gain (subject to recapture at ultimate sale), while a QOF accepts any capital gain, requires only the gain to be invested, and offers the 10-year exclusion that a 1031 exchange cannot. Investors sometimes use each tool for different transactions.
Document everything before year-end. If your fund is relying on the working capital safe harbor that Notice 2026-40 preserves, the written plan and the capital-deployment milestones must be in place before December 31, 2026. After year-end, the chance to cure a missing plan for 2027 acquisitions in a QOZ 1.0 tract may be gone. As with any Your-Money-or-Your-Life tax matter, confirm fund-specific facts with the fund’s counsel and your own tax advisor before acting.
Frequently asked questions
Does the December 31, 2026 gain-inclusion deadline eliminate my 10-year gain exclusion?
No. The December 31, 2026 rule requires you to recognize the gain you originally deferred by investing in the QOF — the gain from the relinquished property. The potential 10-year exclusion on appreciation inside the fund since your contribution is a separate benefit that depends on the fund continuing to qualify. Consult the fund manager and a qualified tax professional for a fund-specific analysis.
What is the working capital safe harbor under Notice 2026-40?
Per advisory-firm summaries of the notice, a QOZB may preserve QOZBP status for property acquired after December 31, 2026 in a QOZ 1.0 tract if it had a documented working capital plan in place and deployed capital consistent with that plan before year-end. The specific funding and deployment thresholds are set out in Notice 2026-40 and must be confirmed with a tax professional before the fund relies on this transition relief.
Which IRS forms does a Qualified Opportunity Fund investment require?
Three. The fund files Form 8996 annually to certify its status and report the 90 percent asset test. As an investor, you report the original deferral election and the eventual gain inclusion on Form 8949 with Schedule D, and you file Form 8997 every year you hold the investment to report your QOF holdings and any deferrals or dispositions. Missing Form 8997 can jeopardize your deferral, so file it each year the investment remains open.
Do states follow the federal Opportunity Zone tax benefits?
Most income-tax states conform to the federal rules, but not all. California, notably, does not conform, so a California resident owes state tax on the deferred gain in the year it is realized and receives no state-level 10-year exclusion. Several other states have only partial conformity. Confirm your state’s treatment before assuming an Opportunity Zone investment is tax-advantaged where you live.
How much of my gain do I have to invest in a Qualified Opportunity Fund?
Only the gain — not the full proceeds. Unlike a 1031 exchange, you reinvest just the eligible capital gain, and it can come from any asset such as stock, a business, or real estate, not only real property. You generally have 180 days from the date the gain would be recognized to invest it in a QOF, though pass-through gains can have an extended window.
If I recognize my deferred gain in 2026, do I lose the Opportunity Zone benefit?
No. Recognizing the deferred gain on your 2026 return is a required, expected event — it marks the end of the deferral period, not the end of your investment. As long as you keep holding the QOF interest and the fund continues to meet its asset tests, you remain on track for the 10-year basis step-up that excludes future appreciation. Notice 2026-40 matters precisely because it affects the fund’s ability to keep qualifying, which is what protects that 10-year benefit.
