How to Invest in Qualified Opportunity Zones: Deferral and Deadlines

To invest in Qualified Opportunity Zones, you start with a capital gain, move that gain into a Qualified Opportunity Fund within 180 days of the sale, elect the deferral on your tax return, and hold the fund investment long enough to earn the program’s tax benefits. The mechanics are straightforward. The timing, right now, is not: deferred gains under the original program come due on December 31, 2026, and a redesigned permanent version of the program takes effect January 1, 2027.

Start With an Eligible Capital Gain

Only certain profits qualify. Eligible gains include capital gains from selling stocks, real estate, or other investment assets, along with Section 1231 gains from business property reported on Form 4797. The gain has to come from a transaction with an unrelated party, and it has to be a gain that would otherwise be recognized for federal tax purposes before January 1, 2027.¹

You have 180 days from the date the gain would be recognized to place the money in a Qualified Opportunity Fund. For a stock sale, that clock starts on the sale date. For a Section 1231 gain, it starts the day the gain is realized.¹ You only need to invest the gain itself, not the full sale proceeds. Sell stock for $200,000 with a $50,000 gain, and $50,000 is all you have to move.

Miss the window and the gain is taxed normally. Long-term capital gains face rates up to 20 percent, and taxpayers above certain income thresholds owe an additional 3.8 percent net investment income tax on top of that.²

Timing for Gains From Partnerships and S Corporations

If your gain comes through a partnership, S corporation, or estate, and the entity does not elect deferral at its own level, you have three possible start dates for your 180-day window:¹

The entity’s sale date
The last day of the entity’s taxable year (typically December 31 for calendar-year entities)
The entity’s return due date without extensions (March 15 for partnerships and S corporations)

The third option gives the most breathing room, which matters when you don’t receive your K-1 until well after year-end. The date you actually receive the K-1 is irrelevant to the calculation.

Choose a Fund: Self-Certify or Invest in a Managed Fund

A Qualified Opportunity Fund has to be organized as a corporation or a partnership with the specific purpose of investing in Opportunity Zone property.³ You can create one yourself or invest in someone else’s.

Self-Certifying Your Own Fund

If you want direct control over a specific project, form an LLC taxed as a partnership (or a corporation) and self-certify it as a Qualified Opportunity Fund by filing Form 8996 with the entity’s tax return. There is no advance application or approval process.⁴

The practical sequence: form the entity under state law, get an Employer Identification Number, draft an operating agreement that states the entity’s purpose is investing in Qualified Opportunity Zone property, and file Form 8996 with the first tax return. State LLC formation fees vary, and some states charge annual fees on top. You will also want a tax professional who understands the 90 percent asset test, because that test is where self-certified funds most often stumble.

Investing in a Managed Fund

Managed funds handle the entity formation, property selection, compliance testing, and reporting. They pool capital from many investors to finance larger developments such as multifamily housing or commercial projects. The trade-off is cost. Managed funds typically charge an annual management fee (often around 2 percent of assets) plus a share of profits if the investment performs well. Those fees reduce the tax benefit, so compare the net return against what a smaller self-directed investment could produce.

Either way, the fund must keep at least 90 percent of its assets in qualified Opportunity Zone property. The IRS tests this twice a year, on the last day of the fund’s first six-month period and on the last day of its tax year, and the fund reports compliance annually on Form 8996.³⁵ A failure isn’t cost-free: the IRS imposes a monthly penalty on the shortfall, and in a partnership fund that penalty flows through to the investors.⁶ Ask any managed fund how it plans to deploy capital fast enough to meet the threshold; a fund with acquisitions or construction already lined up is less likely to trip it.

Know the Property Rules Before Committing Capital

The fund can’t just buy any asset inside an Opportunity Zone. The property has to satisfy either an “original use” test or a “substantial improvement” test, and deals fail here more than anywhere else.

Original Use

Property meets the original use requirement if the fund is the first entity to place it in service within the Opportunity Zone. New construction always qualifies. Used property previously in service outside the zone can also qualify, because the fund is the first to use it inside the zone.¹

Vacant buildings have their own rule. A property counts as original use if it has been vacant for at least three continuous years after the tract was designated an Opportunity Zone, or if it was vacant for at least one year before the designation and stayed vacant through the purchase date.¹

Substantial Improvement

Buying an existing building that doesn’t meet original use means the fund has to substantially improve it. Within any 30-month period after acquisition, the fund must add to the building’s basis an amount that exceeds the building’s adjusted basis at acquisition. Buy a building with an adjusted basis of $500,000 (excluding land), and you need to invest more than $500,000 in improvements within 30 months.⁶

Rural areas get a lower threshold: improvements only need to exceed 50 percent of the adjusted basis.⁷ Land value is excluded from the calculation, which helps where land is expensive relative to the structure.

File the Deferral Election on Your Return

The deferral doesn’t happen automatically. You elect it on the return for the year the gain would otherwise have been recognized, using two forms.

Form 8949

Report the original gain transaction on Form 8949 as normal. Then, on a separate row of the same form, enter the fund’s Employer Identification Number, the date you invested, code “Z” in column (f), and the deferred gain as a negative number in column (g). The negative entry offsets the gain and pulls it out of taxable income for the year.⁸

If you invested gains from multiple sales into the same fund on different dates, each investment gets its own row. Gains of the same character invested on the same date into the same fund can be grouped.⁸

Form 8997

Form 8997 tells the IRS which Qualified Opportunity Fund investments and deferred gains you held at the start and end of the tax year. It requires the fund’s EIN, the acquisition date, and the amount of deferred gain tied to each holding.⁹ Both forms attach to your annual federal return: Form 1040 for individuals, Form 1120 for corporations, and Form 1065 for partnerships.¹⁰

If you already filed the return for the gain year before making the investment, you can amend the return or file an administrative adjustment request to add the election.¹¹

Form 8997 is not a one-time filing. You file it every year you hold the investment.⁹ Skipping a year can trigger an audit or cause the IRS to treat the deferred gain as immediately recognized. Keep copies of every return and its attachments for the full holding period; a 10-year hold means a long paper trail, and it is the only way to substantiate the exclusion when you eventually sell.

Hold Long Enough to Earn the Tax Benefits

The program’s benefits come in three layers, each tied to how long you hold the fund investment.

Deferral. Investing an eligible gain in a Qualified Opportunity Fund postpones the tax on that gain. Under the original program, the deferral runs until you sell the investment or December 31, 2026, whichever comes first.¹
Basis step-up on the deferred gain. A five-year hold excludes 10 percent of the original deferred gain from taxation. A seven-year hold increases the exclusion to 15 percent. Because the deferral ends December 31, 2026, only investors who invested by December 31, 2021 (five years) or December 31, 2019 (seven years) qualify for these reductions.¹
Permanent exclusion of new appreciation. Hold the fund investment for at least 10 years, and you can adjust its basis to fair market value when you sell. Any appreciation earned inside the fund is never federally taxed, provided you make a timely election on the return for the year of sale.¹

The 10-year exclusion is where the wealth-building sits. A fund investment that doubles over a decade generates zero federal tax on that growth.

The December 2026 Deadline and the Permanent Program in 2027

If you deferred a capital gain through a Qualified Opportunity Fund before 2027, the deferred gain becomes taxable on December 31, 2026, even if you haven’t sold your fund interest.¹ The tax on that original gain (less any five-year or seven-year basis step-up you earned) is due with your 2026 return. Many investors get caught out because the bill arrives without a sale to generate cash.

The 10-year exclusion on appreciation, however, does not expire in 2026. Continue holding past the 10-year mark and eventually sell, and the growth remains tax-free. You pay in 2026 on the original deferred gain and keep the permanent exclusion on everything the investment earned beyond that.

The One Big Beautiful Bill Act, signed into law on July 4, 2025, made the Opportunity Zone program permanent. The original program winds down at the end of 2026, and a redesigned permanent version takes over on January 1, 2027. Under the permanent framework, new investments get a rolling five-year deferral that starts on the date you invest rather than ending at a fixed calendar date. The basis step-up is 10 percent for standard zones and 30 percent for rural zones after five years. New zone designations occur every 10 years, with governors nominating tracts and Treasury certifying them. The first new census tracts become effective January 1, 2027, and the original tract designations expire December 31, 2028.¹²

If you are sitting on a capital gain right now, the timing decision is genuinely difficult. Invest under the original rules before year-end and face the 2026 reckoning almost immediately, or wait until 2027 and invest under the permanent framework with a rolling five-year deferral. A tax advisor familiar with both rule sets is worth the consultation.

Transactions That Can End Your Deferral Early

Certain transactions force recognition of the deferred gain before December 31, 2026. The IRS calls these “inclusion events.”¹¹ Common ones include:¹

Selling or exchanging your fund interest, which terminates the deferral on the portion sold
Gifting the interest, which immediately triggers the deferred gain
Fund liquidation before the deferral period ends
Transferring the interest to a non-grantor trust (a revocable grantor trust is not an inclusion event)
Transferring the investment to a spouse under a divorce decree
A cash or property distribution from a partnership-form fund, to the extent the distribution’s fair market value exceeds your basis in the investment

The gifting rule surprises the most people. The deferral is personal to the original investor, so giving the investment to a family member or charitable organization triggers the tax you were trying to postpone.
