Situation One: A federal credit union appears on the Auto-Revocation List, even though federal credit unions are not required to file an annual return. If an organization was recognized by the IRS as exempt under section 501(c)(14)(A) as a state credit union before it became federally chartered under the supervision of the National Credit Union Association (NCUA), IRS records will continue to identify that organization as a state credit union until it notifies the IRS that it is has become a federal credit union. As a state credit union in IRS records, it has an annual filing requirement and it will appear on the Auto-Revocation List if it does not file a return for three consecutive years. A state credit union has an annual filing requirement for all periods before its conversion to a federally chartered credit union. If a federal credit union that was previously a state credit union appears on the Auto-Revocation List, it should write or fax a letter to the IRS. Upon verifying that the organization is a federal credit union, the IRS will remove the organization from the Auto-Revocation List. Please send all inquiries, in writing, explaining your situation to: IRS - TE/GE Attn: Correspondence Unit P.O. Box 2508 Cincinnati, OH 45201 You may also fax the letter to 855-204-6184.
