(a) Form; address. An applicant for enrollment must file an application on Form 23, “Application for Enrollment to Practice Before the Internal Revenue Service,” properly executed under oath or affirmation, with the Director of Practice. The address of the applicant entered on Form 23 will be the address under which a successful applicant is enrolled and is the address to which the Director of Practice will send correspondence concerning enrollment. An enrolled agent must send notification of any change to his or her enrollment address to the Director of Practice, Internal Revenue Service, 1111 Constitution Avenue, NW., Washington, DC 20224, or at such other address specified by the Director of Practice. This notification must include the enrolled agent's name, old address, new address, social security number or tax identification number, signature, and the date.

(b) Fee. The application for enrollment must be accompanied by a check or money order in the amount set forth on Form 23, payable to the Internal Revenue Service, which amount constitutes a fee charged to each applicant for enrollment. This fee will be retained by the United States whether or not the applicant is granted enrollment.

(c) Additional information; examination. The Director of Practice, as a condition to consideration of an application for enrollment, may require the applicant to file additional information and to submit to any written or oral examination under oath or otherwise. The Director of Practice will, on written request filed by an applicant, afford such applicant the opportunity to be heard with respect to his or her application for enrollment.

(d) Temporary recognition. On receipt of a properly executed application, the Director of Practice may grant the applicant temporary recognition to practice pending a determination as to whether enrollment to practice should be granted. Temporary recognition will be granted only in unusual circumstances and it will not be granted, in any circumstance, if the application is not regular on its face, if the information stated in the application, if true, is not sufficient to warrant enrollment to practice, or if there is any information before the Director of Practice indicating that the statements in the application are untrue or that the applicant would not otherwise qualify for enrollment. Issuance of temporary recognition does not constitute enrollment to practice or a finding of eligibility for enrollment, and the temporary recognition may be withdrawn at any time by the Director of Practice.

(e) Appeal from denial of application. The Director of Practice must inform the applicant as to the reason(s) for any denial of an application for enrollment. The applicant may, within 30 days after receipt of the notice of denial of enrollment, file a written appeal of the denial of enrollment with the Secretary of the Treasury or his or her delegate. A decision on the appeal will be rendered by the Secretary of the Treasury, or his or her delegate, as soon as practicable.
