Where Maine is in the process
Maine census tracts list: Opportunity Zones by county
Every Maine census tract that is either on the OZ 2.0 eligibility list (78 tracts, IRS Rev. Proc. 2026-14 appendix) or inside a current (2018) Opportunity Zone, grouped by county. The CDFI Fund's 2018 list has 32 Maine tracts (30 low-income, 2 contiguous), numbered by the 2010 census. GEOIDs here are 2020-census tracts, so we matched the 2018 zones to 2020 tracts with the Census relationship file: they cover 34 2020 tracts fully and 2 partly (36 in this table). "Partly" means only part of the 2020 tract was in a 2018 zone (how we match).
Eligible doesn't mean certified. The governor can nominate up to 25 of these tracts (the 25% cap). The federal nomination window closed September 28, 2026 (a state that takes the single 30-day extension has until October 28), and certified OZ 2.0 zones take effect January 1, 2027. See which states have filed on the OZ 2.0 nomination tracker, check exact boundaries on the eligible-tract map, and read how to plan an OZ investment for January 2027.
