Automatic Exemption Revocation for Non-Filing: Notifying Organization

How does my organization know that it has been automatically revoked?

A list (the Auto-Revocation List) of automatically revoked organizations, updated monthly, is on the IRS website. For each organization, the Auto-Revocation List provides the name, last known address, employer identification number (EIN), subsection of exemption, effective date of revocation, date the name is published on the Auto-Revocation List, and the exemption reinstatement date.

In addition, the IRS sends a letter to each organization, at its last known address, stating that its exempt status has been automatically revoked because it has not filed a required annual return or notice for three consecutive years.
