> **Judge an opportunity zone fund as an investment first and a tax shelter second.** Check the sponsor’s record with the same kind of project, every fee layer, how the fund passes the 90% and QOZB tests, whether it will help you pay tax when the deferral ends, and how investors exit after year 10. Treat promises of guaranteed returns or “IRS-approved” status as red flags.

## Key takeaways

- The tax benefit only multiplies a good investment. A weak project with a tax break still loses money.
- Ask for every fee in writing: acquisition, asset management, development, disposition and the promote.
- Ask how the fund has passed the 90% test and whether it has ever paid a §1400Z-2(f) penalty.
- Selling before 10 years forfeits the tax-free growth. Know the fund’s exit plan and any liquidity options.
- No QOF is “IRS-approved”; funds self-certify.

## The sponsor and the deal

- How many projects of this type, in this kind of market, has the sponsor completed, and what did investors actually earn?
- Is this a single-asset fund or a portfolio? Single-asset funds are simpler to evaluate but concentrate risk.
- What are the construction budget, contingency, financing terms and guarantees? Who bears cost overruns?
- What does the project look like if it earns nothing from the tax benefit: would you invest anyway?

## Fees

Forum investors repeatedly report learning about fee layers after the fact. Get a full fee table: acquisition or placement fees, annual asset-management fees (often 1–2% of committed or invested capital), development and construction-management fees, disposition fees, and the sponsor’s promote (a share of profits above a preferred return). Fees reduce exactly the growth the 10-year exclusion makes tax-free.

## Tax compliance

- How does the fund pass the [90% asset test](https://fundtaxes.com/blog/form-8996-qof-90-percent-asset-test), and does it test the QOZB below it on the same dates?
- Has it adopted written working-capital plans, and is construction on the plan’s schedule?
- Has it ever owed a §1400Z-2(f) penalty, and who paid it?
- Is it ready for the new OZ 2.0 information returns and their daily penalties?
- Will you get a K-1 (partnership fund) or a 1099 (corporate or REIT fund), and when? Late K-1s delay your return.

## Cash for your tax bill

The deferred gain becomes taxable on December 31, 2026 for existing investments and five years after investment under OZ 2.0, whether or not the fund distributes anything. Ask whether the fund plans tax distributions, and plan your own cash. The [inclusion calculator](https://fundtaxes.com/blog/opportunity-zone-2026-inclusion-form-8997) shows the amount.

## The exit after year 10

The 10-year exclusion applies when your QOF interest is sold, and the regulations also let investors in a partnership or S corporation fund elect to exclude gain when the fund sells its property after 10 years. Ask whether the operating agreement lets you use that election, how the sponsor plans to exit, and what happens if you need to sell earlier.

## If you sell before 10 years

Selling early triggers any deferred gain still outstanding (less step-ups earned) and ordinary tax on the investment’s growth, with no exclusion. You can roll the proceeds into another QOF within 180 days to defer again, but the 10-year clock starts over.

> Interactive checklist: sponsor track record, full fee table, audited financials, 90% and QOZB testing method, working-capital plans, penalty history, OZ 2.0 reporting readiness, K-1 or 1099 timing, tax-distribution policy, 10-year exit plan and operating-agreement election; red flags are guaranteed returns, "IRS-approved" claims and pressure to invest before the 180th day without documents.

## Frequently asked questions

### How do I know if an opportunity zone fund is legitimate?

Check the sponsor’s record with similar projects, audited financials, a full fee table and how the fund documents its 90% and QOZB testing. No fund is IRS-approved; claims of guaranteed returns or IRS approval are red flags.

### What fees do opportunity zone funds charge?

Common layers are acquisition or placement fees, annual asset-management fees, development fees, disposition fees and a promote above a preferred return. Ask for every fee in writing before investing.

### What happens if I sell my opportunity zone investment before 10 years?

Any deferred gain still outstanding is taxed (less step-ups you have earned), the investment’s growth is taxed normally, and you lose the 10-year exclusion. Rolling the proceeds into another QOF within 180 days can defer again, but the holding period restarts.

### Will I get a K-1 or a 1099 from an opportunity zone fund?

A fund taxed as a partnership sends a K-1; a fund taxed as a corporation (including a REIT structure) sends a 1099. Either way you file Form 8997 yourself.

### What returns do opportunity zone funds make?

Returns depend on the projects. Compare the after-fee, pre-tax return with a similar taxable investment, then add the tax benefit using the benefits calculator; sponsor projections are not guarantees.
