Here's how to look up 501c3 revocations. Tom Automatic Revocation of Exemption List The IRS publishes 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 organization's name, employer identification number (EIN), organization (subsection) code, last known address, effective date of revocation, and the date the organization's name was posted on IRS.gov. The list will be updated monthly as organizations lose their tax-exempt status for not filing. Additional updates will be made as necessary. The date at the bottom of this web page indicates when this page was last updated. http://www.irs.gov/charities/article/0,,id=240099,00.html ===== e-mail: k1ki@arrl.org ARRL New England Division Director http://www.arrl.org/ Tom Frenaye, K1KI, P O Box J, West Suffield CT 06093 Phone: 860-668-5444
