## Definition

An Opportunity Zone is an economically distressed census tract in which investors can defer (and potentially exclude) capital gains by investing eligible gains into a Qualified Opportunity Fund (QOF) within 180 days. Originally created by the Tax Cuts and Jobs Act of 2017, the program was made permanent by the One Big Beautiful Bill Act (signed July 4, 2025): for investments made on or after January 1, 2027, deferred gain is recognized at the earlier of disposition or the 5-year anniversary of the QOF investment, with new tract designations every 10 years starting July 1, 2026.

## Key takeaways

- Opportunity Zones were created by the TCJA of 2017 and made permanent by the One Big Beautiful Bill Act in 2025.
- Investors must roll eligible capital gains into a Qualified Opportunity Fund (QOF) within 180 days of realization to access the tax benefits.
- For gains recognized BEFORE December 31, 2026: original TCJA program applies (deferral until earlier of sale or Dec 31, 2026; 10% basis step-up at 5 years pre-2026).
- For investments made ON OR AFTER January 1, 2027: deferral until earlier of sale or 5-year anniversary; 10% basis step-up at 5 years (30% for Qualified Rural Opportunity Funds); designations rotate every 10 years; contiguous tracts no longer eligible.
- Holding a QOF investment 10+ years still permits a basis step-up to fair market value, excluding post-investment appreciation — capped at the 30-year mark under the new rules.

## How Olomon thinks about this

_The following section is Olomon's first-party perspective, informed by our work building a financial system of record. It is intentionally separated from the neutral definitional content above._

Opportunity Zone investments often live entirely outside a household's normal brokerage view — making it easy to lose track of basis, the 180-day clock, and the 10-year exclusion milestone. Olomon stores QOF investment terms, contribution dates, milestone dates, and supporting documentation in one place so the household, CPA, and attorney are looking at the same record.

## In-depth definition

Opportunity Zones (OZs) were established as part of the Tax Cuts and Jobs Act of 2017 (TCJA). The IRS-designated census tracts cover roughly 8,700 communities across all 50 states, D.C., and U.S. territories. The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, made the program permanent and rewrote several core mechanics for investments made on or after January 1, 2027 — the original TCJA rules continue to govern gains recognized through the end of 2026.

### Pre-2027 program (TCJA): three core tax benefits

1. Deferral: the original [capital gain](https://olomon.com/financial-glossary/capital-gains) is not recognized until the QOF investment is sold or December 31, 2026, whichever comes first.
2. Reduction: 10% basis step-up if the investment was held 5 years before December 31, 2026 (the additional 5-year/15% step-up window has closed).
3. Exclusion: if the QOF investment is held at least 10 years, the basis can be stepped up to fair market value on the date of sale, excluding post-investment appreciation from federal tax.

### Post-2027 program (OBBBA): permanent rolling structure

1. Deferral until the earlier of sale or the 5-year anniversary of the QOF investment (replacing the December 31, 2026 cutoff).
2. 10% basis step-up at the 5-year mark on the deferred gain (30% for Qualified Rural Opportunity Funds, a new OBBBA category).
3. 10-year hold permits a basis step-up to fair market value, capped at the 30-year mark from the date of investment.
4. New designations every 10 years beginning July 1, 2026; tracts must have median family income below 70% of state/metro median or a 20% poverty rate combined with median income below 125% of state/metro median; contiguous-tract eligibility eliminated.

## How to invest gains in an Opportunity Zone

The procedural steps for an investor with eligible capital gains to invest those gains in a Qualified Opportunity Fund and capture the 10-year exclusion benefit.

1. **Realize an eligible capital gain** — Eligible gains include capital gains from the sale of stock, mutual funds, real estate, business interests, and other capital assets. Section 1231 net gains have specific timing rules — confirm with your CPA.
2. **Select or form a Qualified Opportunity Fund (QOF)** — Invest only the gain amount (not the full sale proceeds) in a QOF. The QOF must self-certify on IRS Form 8996 and meet the 90% asset test on a semi-annual basis.
3. **Invest within 180 days** _(Within 180 days of gain realization)_ — Roll the eligible gain into the QOF within 180 days of the gain realization date. Document the date, amount, and gain source for the eventual filing.
4. **Report the deferral on Form 8949 + Form 8997** _(With that year's tax return)_ — Report the deferred gain on Form 8949 with Schedule D, and file Form 8997 (Initial and Annual Statement of QOF Investments) with each annual return until you exit.
5. **Hold for 10+ years to capture the exclusion** _(10+ years from QOF investment)_ — If the QOF investment is held at least 10 years, the investor may elect a basis step-up to fair market value on sale, excluding post-investment appreciation from federal capital gains tax. Under post-OBBBA rules (investments made on or after January 1, 2027), this 10-year exclusion is capped at the fair market value on the 30-year anniversary of the investment.

## Frequently asked questions

### What kind of gains qualify for Opportunity Zone treatment?

Eligible gains generally include capital gains from the sale of stock, mutual funds, real estate, business interests, and other capital assets, provided the gain is invested in a QOF within 180 days. Section 1231 net gains have specific timing rules.

### Are Opportunity Zone investments only real estate?

No. QOFs can invest in qualified Opportunity Zone businesses or property, which includes both real estate development and operating businesses meeting specific tests around tangible property, employees, and revenue derived in the zone.

### Did the One Big Beautiful Bill Act change the Opportunity Zone program?

Yes. OBBBA, signed July 4, 2025, made the program permanent. For investments made on or after January 1, 2027: deferral runs until the earlier of sale or the 5-year anniversary of the QOF investment (replacing the original December 31, 2026 cutoff); the basis step-up at 5 years is 10% (30% for the new Qualified Rural Opportunity Fund category); designations rotate every 10 years starting July 1, 2026; eligibility tightened (median family income below 70% of state/metro or 20% poverty + median income below 125%); and contiguous tracts no longer qualify. The original TCJA rules continue to govern gains recognized through the end of 2026.
