The official qualified opportunity zones map is hosted by the Community Development Financial Institutions Fund, a division of the U.S. Treasury, and it covers the 8,764 census tracts designated under the Tax Cuts and Jobs Act of 2017 across all 50 states, the District of Columbia, and five U.S. territories.1U.S. Department of Housing and Urban Development. Opportunity Zones The map matters because the tax benefits attached to these zones turn on whether a specific parcel sits inside a designated tract boundary. A property one block outside the line gets nothing.
Where the Official Map Lives
The CDFI Fund maintains the only authoritative interactive map. You reach it through the agency’s Opportunity Zones Resources page, which links to the mapping tool built on the CDFI Fund’s CIMS platform.2Community Development Financial Institutions Fund. Opportunity Zones Resources The IRS handles the tax side of the program, but the CDFI Fund supports designation and mapping under IRC 1400Z-1.
If you want the raw list instead of the visual, IRS Notice 2018-48 contains every census tract the Secretary of the Treasury designated as a Qualified Opportunity Zone,3Internal Revenue Service. Internal Revenue Service Notice 2018-48 and IRS Notice 2019-42 added two more tracts in Puerto Rico.4Internal Revenue Service. Internal Revenue Service Notice 2019-42 Together, those two notices are the legal foundation for which tracts qualify. Third-party mapping sites exist, but they are only as current as their last pull from these sources.
How to Check a Specific Address
The CDFI Fund tool accepts address searches, but the more reliable method is to convert the address to a census tract number first and then search the map by that number. Census tract boundaries don’t follow street names or zip codes, so an address search alone can be ambiguous near a boundary line.
To find the tract number, use the U.S. Census Bureau’s free Geocoder. Enter street address, city, and state, and it returns the census tract identifier.5U.S. Census Bureau. Census Geocoder Take that number to the CDFI Fund mapping tool. The CDFI Fund instructs users to click the mailbox icon next to the search bar, select “2015 NMTC Tract,” and confirm the “Opportunity Zone” layer is turned on so only designated tracts appear.2Community Development Financial Institutions Fund. Opportunity Zones Resources
Zoom to street level once the map centers on the area. At wider zoom levels, a parcel near a boundary line can look inside the zone when it is actually outside. Clicking a shaded tract usually opens a sidebar with the tract’s data, giving you a second confirmation. That verification step is worth the extra minute. Investors who skip it and rely on a quick glance have had deals fall apart during due diligence.
Why the Map Still Uses 2010 Census Boundaries
All current Opportunity Zone designations are tied to the 2010 Census tract map, not 2020. The original 2018 designations were based on 2010 boundaries, and those boundaries have not been updated for the existing program. The Geocoder results and the CDFI Fund map both reference 2010 geographic definitions. If you compare data from a source using 2020 Census tracts, the numbers and boundary lines will not match, which creates confusion near edges where the Census Bureau redrew lines.
What Falling Inside a Zone Gets You Now
The reason to check the map is to confirm eligibility for the tax incentives Congress attached to these tracts. Three benefits exist, but not all are still fully available.
The first is deferral. When you invest an eligible gain into a Qualified Opportunity Fund, federal tax on that gain is deferred until the earlier of the date you sell the QOF investment or December 31, 2026.6Internal Revenue Service. Opportunity Zones Frequently Asked Questions Capital gains and qualified Section 1231 gains qualify. Ordinary income does not, and gains from transactions with a related person are excluded.
The second is a basis step-up on the deferred gain. A five-year hold earned a 10 percent exclusion; a seven-year hold earned 15 percent. Both windows have closed for new investors. Reaching the seven-year mark before the December 31, 2026, recognition date required investing by the end of 2019, and the five-year window closed at the end of 2021.6Internal Revenue Service. Opportunity Zones Frequently Asked Questions
The third is the one that still drives new investment. Hold a QOF investment for at least 10 years and you can elect to step the basis up to fair market value on sale, permanently eliminating tax on the appreciation that occurred inside the fund.7Internal Revenue Service. Invest in a Qualified Opportunity Fund
To claim any of this, you have to move the gain into a QOF in exchange for an equity interest within 180 days of realizing it. The clock starts on the day the gain would otherwise be recognized for federal income tax purposes.7Internal Revenue Service. Invest in a Qualified Opportunity Fund Lending money to a fund through a debt instrument does not count.
The December 31, 2026, Recognition Date
This is the date that shapes every current holding. All previously deferred capital gains have to be recognized on December 31, 2026, unless an earlier sale or inclusion event already triggered recognition.6Internal Revenue Service. Opportunity Zones Frequently Asked Questions The deferred gain shows up on the 2026 return whether or not you still hold the fund investment.
The 10-year exclusion runs on a separate clock. Even after the deferred gain is recognized in 2026, you can keep holding the QOF investment, and if the total hold reaches 10 years, the appreciation inside the fund itself is still eligible for permanent exclusion when you eventually sell.7Internal Revenue Service. Invest in a Qualified Opportunity Fund Two different benefits, two different timelines. Confusing them is a common mistake.
A New Map Takes Effect January 1, 2027
The One Big Beautiful Bill Act, signed on July 4, 2025, created a permanent redesignation of the Opportunity Zone program, referred to as OZ 2.0, effective January 1, 2027.8U.S. Department of Housing and Urban Development. Opportunity Zones Updates Several changes reshape what the map will show.
- New designations will use 2020 Census tract maps rather than 2010, so tract numbers and boundary lines will shift.
- To qualify, a tract must have a median family income at or below 70 percent of the area median, or a poverty rate of at least 20 percent combined with a median income at or below 125 percent of the area median.
- The prior option letting states designate up to five percent of their zones from contiguous non-qualifying tracts is eliminated.
- Designations will run in 10-year cycles (2027, 2037, 2047), replacing the one-time structure of the current program.
- A 10 percent basis step-up returns for investments held at least five years, and investments in rural areas through a Qualified Rural Opportunity Fund get a 30 percent exclusion at the five-year mark.
Treasury is expected to certify the new OZ 2.0 tracts in the fourth quarter of 2026, with designations taking effect January 1, 2027.8U.S. Department of Housing and Urban Development. Opportunity Zones Updates The current CDFI Fund map will become outdated for investments made after that date. About 60 percent of existing zones are expected to qualify under the tighter criteria, so a project that stretches into 2027 needs to check the target tract against both the current map and the coming OZ 2.0 designations.
