The filing requirements for a tax-exempt organization generally start with the tax year in which it was legally formed. When an organization applies for an EIN, the IRS considers it legally formed and a filing requirement is established. If the organization doesn't satisfy that filing requirement for three consecutive years after the formation date, its exemption will be automatically revoked. If an organization on the Auto-Revocation List was not legally formed in the same tax year it requested its EIN, or if the organization believes it was erroneously revoked because the IRS used the EIN application date for purposes of automatic revocation, it should send a statement indicating its legal formation date directly to the Exempt Organizations Entity Unit.
