Wisconsin's OZ 2.0 map is final. 77 tracts are designated, effective January 1, 2027, replacing the 120 current zones, which remain in effect through December 31, 2028.
This map opens on the official 2027 designated Wisconsin Opportunity Zones (deep blue), effective January 1, 2027, from the list Treasury published November 5, 2026. Use the Layers panel to see the original 2018 zones (gold, in effect through December 31, 2028), both maps together, or the non-final eligible pool. On the 2027 view, the rural toggle shows only tracts marked Rural on the official list. See every designated Wisconsin tract on the 2027 list.
Wisconsin has 120 designated Qualified Opportunity Zones across 52 counties, with the largest concentrations in Milwaukee County, Dane County (Madison), and Brown County (Green Bay). Wisconsin's OZ program spans its urban industrial core, growing mid-sized cities, and rural agricultural and timber communities across the state.
Milwaukee's OZs cover large portions of the city's north and south sides, historically disinvested neighborhoods that have begun to attract investor interest driven by low land costs, anchor institutions like Marquette University and the Medical College of Wisconsin, and the city's improving quality of life indicators. Madison's zones offer urban infill housing and commercial opportunities adjacent to the University of Wisconsin and the state's growing technology sector. Green Bay and Fox Valley zones present workforce housing and light industrial investment opportunities in a region with strong manufacturing and food processing employment.
All OZ 1.0 designations remain in effect through December 31, 2028. Wisconsin's manufacturing heritage, agricultural economy, and improving urban investment climate provide a stable foundation for OZ capital deployment.
