Qualified Opportunity Funds, explained

What a Qualified Opportunity Fund is

A Qualified Opportunity Fund, or QOF, is the vehicle that makes the Opportunity Zone tax benefits work. It is a partnership or a corporation set up for the purpose of investing in Opportunity Zone property (IRC §1400Z-2(d)(1)). Most QOFs are LLCs taxed as partnerships.

You cannot get the Opportunity Zone tax benefits by buying a property in a zone on your own. The capital gain has to go into a QOF first. The fund then puts that money to work inside a zone, It can own property directly, or it can invest in a business that operates there.

There is no application and no approval from the IRS. A fund certifies itself by filing Form 8996 with its tax return. That simplicity is a big part of the appeal. It also means the fund carries the burden of proving it followed the rules, year after year.

If you are new to the program, start with what an Opportunity Zone is, then come back here.

How a QOF fits into the program

The money moves in a simple chain:

1. You sell an asset at a gain. That can be stock, a business, real estate, crypto, or another capital asset.
2. Within 180 days, you invest the gain in a QOF (IRC §1400Z-2(a)). See how the 180-day clock works.
3. The QOF invests in qualified Opportunity Zone property. That can be property the fund owns itself, or an ownership interest in a qualified Opportunity Zone business, often called a QOZB.
4. You elect the deferral on your tax return and report the investment every year on Form 8997.

Only the gain needs to go in. You can keep your original basis. If you invest more than your gain, the extra money is treated like a normal investment with no Opportunity Zone tax breaks, and the fund tracks the two pieces separately.

The 90% asset test

The core rule for a QOF is simple to say. At least 90% of the fund's assets must be qualified Opportunity Zone property (IRC §1400Z-2(d)(1)).

The fund measures this twice a year:

• On the last day of the first six months of the fund's tax year
• On the last day of the fund's tax year

The fund reports the result each year on Form 8996. If it falls short, it can owe a penalty for each month it misses, unless it can show reasonable cause.

The hard part is timing. A fund that raises cash and holds it while a deal comes together can fail the test quickly, because cash sitting in the fund is not qualified property. This is the main reason most funds use a two-tier structure, explained next.

Why most funds use a two-tier structure

A QOF can own property directly. Most do not. Instead, the QOF invests in a separate entity that runs the business or owns the real estate. That lower entity is the qualified Opportunity Zone business, or QOZB.

The QOZB plays by a different set of rules, and those rules are more forgiving in practice:

• At least 70% of the tangible property the business owns or leases must be qualified Opportunity Zone business property.
• At least half of the business's gross income must come from the active conduct of its business inside the zone.
• It can rely on the working capital safe harbor. Cash set aside under a written plan and schedule counts as a qualified asset while it is being spent on the project. Each plan covers up to 31 months, and a business can use more than one plan, for up to 62 months in total.

The result is breathing room. The investor's money lands in the QOF, the QOF moves it down to the QOZB, and the QOZB can hold it while construction or startup happens without breaking the 90% test at the fund level.

What counts as qualified property

Property the fund or business buys generally qualifies if it was bought after 2017 from an unrelated party, it is used in the zone, and one of two things is true:

• Original use. The property is new to the zone, like a newly built building or new equipment put into service there for the first time.
• Substantial improvement. For an existing building, the fund or business must improve it by more than its purchase price, not counting land, within 30 months. In rural zones, the bar has been more than 50% of the building's basis since July 4, 2025.

Land itself does not have to be improved, but it has to be used in an active business. Buying raw land and holding it for appreciation does not work.

A short example. A QOZB buys an older building in a zone for $1 million, with $200,000 of that allocated to land. To meet substantial improvement, it needs to spend more than $800,000 improving the building within 30 months. In a rural zone, the bar would be more than $400,000.

Who a QOF fits

A QOF makes the most sense when there is a real gain, a real project, and a long time horizon. The people we see use them most:

• Investors who sold stock, a business, or real estate and want to defer the tax while putting the money into something they can hold for ten years.
• Business owners who want to start or grow an operating business in a zone and fund it with their own gain.
• Developers who build housing, hospitality, or commercial projects in zones and raise money from investors with gains.
• CPAs and advisors whose clients have a large gain and a 180-day window that is already running.

A QOF is a poor fit if you need the money back in a few years, if the only reason to invest is the tax break, or if nobody is ready to keep the records the rules require. The tax benefit makes a strong project stronger. It does not rescue a weak one.

If you are weighing an Opportunity Zone against a 1031 exchange, read how the two compare.

How to set up a QOF

Setting up a fund is mostly paperwork, but the details matter. The usual steps:

1. Form the entity. Most funds are LLCs taxed as partnerships. Many sponsors form the QOZB at the same time.
2. Get an EIN for each entity.
3. Sign an operating agreement written for Opportunity Zone rules. It should state the fund's purpose and include the provisions the fund needs to stay compliant.
4. Choose the fund's first month. This sets the testing dates, so pick it with the timing of your investment in mind.
5. Self-certify on Form 8996 with the fund's first tax return.
6. Receive the investment within the investor's 180-day window and keep proof of the date and amount.

Timing is where people get hurt. If the 180-day window closes before the fund exists and has a bank account, the deferral is lost. Start early.

Your own fund or someone else's

You have two basic paths.

Invest in an existing fund

• A sponsor finds the deals, runs the projects, and handles compliance.
• You give up control over what gets built, when you can exit, and how the fund is valued.
• Many funds have minimum investments and fees, and you are trusting the sponsor's record keeping.

Set up your own fund

• Often called a captive fund. You control the investment, the timing, and the exit.
• It fits investors with a specific project, business owners who want to invest in their own operating business, and developers.
• You take on the compliance work, or you hire it out.

A middle path

Some investors set up their own fund and invest alongside a developer or operator they trust. The fund stays yours, so you control the timing and the records, while the project is run by people who build or operate for a living. This works well for family groups, business partners, and clients of the same advisor who want to invest in one local project together.

No single path is right for everyone. The deal underneath matters more than the structure. As Ashley says, sometimes the juice ain't worth the squeeze.

Staying compliant for the full hold

Setting up a fund takes weeks. Keeping it compliant takes ten years or more. Most of the problems we see come from the years after setup.

• Form 8996 every year. The fund certifies itself and reports the 90% test (see Forms 8996 and 8997).
• Form 8997 every year for each investor. It tracks what you invested, when, and what you still hold.
• New reporting under Public Law 119-21. Funds now report details about the businesses they invest in, including names, industry codes, residential units, and approximate employee counts. Businesses must give their funds the information they need.
• Proposed regulations. Treasury published proposed rules on September 11, 2026 that add data points and set the first rules for decertifying a fund. They are proposed, so details can change.
• An audit trail. Keep the documents that prove each test: asset values on testing dates, the working capital plan and spending, improvement costs, leases, and income sources.

Your tax preparer files the returns. The fund's records are what make those returns hold up if the IRS asks.

Common mistakes

• Missing the 180-day window because the fund was not ready in time.
• Holding cash in the QOF instead of moving it to the QOZB under a working capital plan.
• A working capital plan that is vague, missing, or not followed.
• Underestimating the substantial improvement requirement on an existing building.
• Buying from a related party.
• Skipping Form 8996 or Form 8997 in a year, or filing them with numbers the records cannot support.
• No audit trail. Funds that cannot prove their tests on the testing dates are the ones that get hurt in an exam.

Most of these are cheap to prevent and expensive to fix later.

What OZ 2.0 changes for funds

Public Law 119-21 made the program permanent. For money invested on or after January 1, 2027, the rules change (see What is OZ 2.0?):

• Rolling deferral. Each investment defers the gain for five years from the day it is made, or until it is sold.
• Step-up. Hold five years and the taxable part of the deferred gain drops by 10%. In a qualified rural opportunity fund, which holds at least 90% of its assets in rural zones, it drops by 30%. See rural Opportunity Zones.
• Tax-free growth. Hold ten years and the growth can be free of federal capital gains tax. If you hold past 30 years, the value is measured at the 30-year anniversary.
• A new map. New zones take effect January 1, 2027 and run through December 31, 2036. Check any address on the OZ 2.0 map.

Funds in today's zones

The original zones stay designated through December 31, 2028 (December 31, 2027 in Puerto Rico). Notice 2026-40 says the IRS intends to propose rules under which money invested after 2026 generally cannot go into new property in an original zone that is not on the new map unless a written working capital plan was in place by December 31, 2026, with at least 10% of the planned capital received and at least 5% spent. Funds and businesses that started before a zone expires would be able to keep treating it as a qualified zone for certain tests through December 31, 2047.

These rules come from IRS Notice 2026-40, which describes regulations the IRS plans to propose. Confirm the current status with your advisor before acting.

Getting out of a QOF

How and when you leave the fund decides how much of the tax benefit you keep.

• Before the deferral ends. Selling some or all of your fund interest early generally brings that share of the deferred gain into income in the year you sell.
• When the deferral ends. Under OZ 2.0, the deferred gain comes due five years after you invest, even if you still hold, so plan the cash. Under the original program, all deferred gains came due December 31, 2026 (see what happens on December 31, 2026).
• After ten years. You can elect to treat your basis as the fair market value when you sell, so the growth on the investment is free of federal capital gains tax (IRC §1400Z-2(c)). Under OZ 2.0, value after the 30-year anniversary does not get this treatment.

Distributions, refinancing, and transfers of fund interests can have their own tax results. Plan exits with your CPA well ahead of time, and keep the fund's records ready, because the ten-year election depends on proving your investment dates and amounts.
