Energy community map: check an address
Instead of zooming a map, type the site address. You get the same official answer the map shows, plus the tract and MSA ids you need for the file.
How the energy community bonus works
A qualifying project located in an energy community gets a larger credit:
- Investment tax credit (48 / 48E): +10 percentage points (e.g. 30% to 40%) if prevailing wage and apprenticeship rules are met; +2 points otherwise.
- Production tax credit (45 / 45Y): the credit amount is increased by 10%.

Questions
How much is the energy community bonus worth?
For the investment tax credit (48 / 48E) the bonus adds 10 percentage points to the credit rate when prevailing wage and apprenticeship requirements are met (for example 30% to 40%), or 2 points for projects that do not meet them. For the production tax credit (45 / 45Y) the credit amount is increased by 10%.

Which IRS list is current?
IRS Notice 2026-39. Its Appendix 1 lists the statistical areas that qualify based on 2025 unemployment rates (BLS LAUS released May 19, 2026) and fossil fuel employment through the 2023 County Business Patterns; that status is applicable as of June 10, 2026 until the next annual update. Its Appendix 2 adds coal closure tracts using MSHA and EIA data as of May 4, 2026.

What are vintage 1 and vintage 2?
Since 2025 Treasury tests every county under two groupings of counties into MSAs and non-MSAs: vintage 1 (based on the 2010 Census) and vintage 2 (based on the 2020 Census). A county qualifies if it passes both the fossil fuel employment and unemployment tests under the same vintage; qualifying under either vintage is enough.
When is the location tested?
Generally when the project is placed in service. Notice 2023-29 also lets a project that is in an energy community on the date construction begins keep that status (a beginning-of-construction safe harbor). Statistical-area status changes every year with the unemployment data; coal closure tracts keep their status.

Can a map tell me if my site is a brownfield?
No. The brownfield category is parcel-specific: a site within the CERCLA definition of a brownfield, or one that meets a Notice 2023-29 safe harbor (for example a site previously assessed through federal, state or tribal brownfield programs, or one with a Phase II environmental site assessment showing a hazardous substance). Census tracts and counties cannot answer it, so ECQualify reports it as not determinable.
