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.
