What Is an Opportunity Zone?

An Opportunity Zone is a designated low-income census tract where investment through a Qualified Opportunity Fund can qualify for federal Opportunity Zone tax benefits.

It is geography, not a fund. The tract is the zone. The QOF is the vehicle. The operating project is usually a Qualified Opportunity Zone Business sitting under the QOF.

For current designations, use the OZ 2.0 map — not the 2018 HUD map.

The three tax benefits, in one paragraph

Investors who reinvest capital gains into a QOF within 180 calendar days can receive three layered federal benefits: deferral of the original gain, a 10% basis step-up after five years under OZ 2.0 (30% for a qualified rural QOF), and 100% exclusion of appreciation on the QOF investment if it is held for 10 years or more. The full tax math is in Opportunity Zone tax benefits. This page does not re-litigate it.

OZ 1.0 vs OZ 2.0 tracts

The original Opportunity Zone map was a one-time 2018 designation: 8,764 tracts across 50 states, the District of Columbia, Puerto Rico, and U.S. territories.

OZ 2.0 replaces that map for new QOF investments. New designations become effective January 1, 2027. Because eligibility tightened — a 70% median-family-income threshold instead of 80%, no contiguous-tract option, and no Puerto Rico blanket designation — the total is expected to drop to roughly 6,500 tracts, a reduction of about 25 percent. Designations then refresh on a rolling 10-year cycle.

OZ 2.0 investments are those made on or after January 1, 2027. Pre-2027 investments stay on OZ 1.0 rules, including the December 31, 2026 deferral recognition date.

The side-by-side on tax benefits, permanence, and the map is in OZ 1.0 vs OZ 2.0.

How a tract becomes a zone: eligible → nominated → designated

Not every poor census tract is an Opportunity Zone. The statute sets a three-step path:

1. Eligible. The tract meets the low-income tests (poverty rate and/or median family income against the OZ 2.0 thresholds).
2. Nominated. The governor nominates a subset of eligible tracts. Each state may nominate no more than 25% of its eligible tracts (with a small-state minimum).
3. Designated. Treasury reviews and certifies the nominations. Certified tracts become Opportunity Zones when the new map takes effect.

The OZ 2.0 nomination window opens July 1, 2026 and runs through late September 2026. Treasury then reviews nominations, and the new map is effective January 1, 2027.

You do not have to live in the zone

You do not have to live in or near an Opportunity Zone to invest. The benefits attach to where the QOF invests, not where the investor lives. The QOF — a domestic corporation or partnership that self-certifies on Form 8996 — is the entity that must put capital into Qualified Opportunity Zone property. See what a Qualified Opportunity Fund is.

Most QOF capital goes into real estate

Real estate is the dominant asset class inside the program: ground-up development, substantial improvement of existing buildings, and related property tests (original use vs doubling basis, with a lower 50% substantial-improvement threshold for rural property). If that is the use case, start with Opportunity Zone real estate investing.

Check the map

Do not rely on a 2018 printout or a HUD layer from the first designation round. Open the OZ 2.0 Opportunity Zone map to see tracts, then read OZ 1.0 vs OZ 2.0 for what the January 1, 2027 transition actually changes.
