IRS posts automatic exemption revocation list
The IRS has started publishing a list of organizations that have had their federal tax-exempt status automatically revoked for failing to file an annual information return or notice with the IRS for three consecutive years. The Automatic Revocation of Exemption List (Auto-Revocation List) is available in Adobe and Excel formats, and divided into separate lists by jurisdiction. The Auto-Revocation List provides the name, employer identification number (EIN), organization (subsection) code, last known address, effective date of revocation, and date on which the name was posted on IRS.gov.
This chart  categorizes automatically revoked organizations by state. For each state, lists are provided using Adobe Acrobat and Microsoft Excel formats.
