Chapter 1. BOARD OF ACCOUNTANCY
§ 109. Substantial equivalency.

(a) (1) An individual whose principal place of business is not in this State and who holds a valid license as a certified public accountant from any state which the NASBA National Qualification Appraisal Service has verified to be in substantial equivalence with the CPA licensure requirements of the AICPA/NASBA Uniform Accountancy Act shall be presumed to have qualifications substantially equivalent to this State's requirements and shall have all the privileges of permit holders of this State without the need to obtain a permit under § 108 of this title. Notwithstanding any other provision of law, an individual who offers or renders professional services, whether in person, by mail, telephone or electronic means, under this section shall be granted practice privileges in this State and no notice or other submission shall be provided by any such individual. Such an individual shall be subject to the requirements in paragraph (a)(3) of this section.
(2) An individual whose principal place of business is not in this State and who holds a valid license as a certified public accountant from any state which the NASBA National Qualification Appraisal Service has not verified to be in substantial equivalence with the CPA licensure requirements of the AICPA/NASBA Uniform Accountancy Act shall be presumed to have qualifications substantially equivalent to this State's requirements and shall have all the privileges of permit holders of this State without the need to obtain a permit under § 108 of this title if such individual obtains from the NASBA National Qualification Appraisal Service verification that such individual's CPA qualifications are substantially equivalent to the CPA licensure requirements of the AICPA/NASBA Uniform Accountancy Act. Any individual who passed the Uniform CPA Examination and holds a valid license issued by any other state prior to January 1, 2012, may be exempt from the education requirement in § 107(c) of this title for purposes of this paragraph (a)(2). Notwithstanding any other provision of law, an individual who offers or renders professional services, whether in person, by mail, telephone or electronic means, under this section shall be granted practice privileges in this State and no notice or other submission shall be provided by any such individual. Such an individual shall be subject to the requirements in paragraph (a)(3) of this section.
(3) An individual licensee of another state exercising the privilege afforded under this section and the firm which employs that licensee hereby simultaneously consent, as a condition of the grant of this privilege:

a. To the personal and subject matter jurisdiction and disciplinary authority of the Board;
b. To comply with this chapter and the Board's rules;
c. That in the event the license from the state of the individual's principal place of business is no longer valid, the individual will cease offering or rendering professional services in this State individually and on behalf of a firm; and
d. To the appointment of the State Board which issued their license as their agent upon whom process may be served in any action or proceeding by this Board against the licensee.
(b) A permit holder of this State offering or rendering services or using that permit holder's CPA title in another state shall be subject to disciplinary action in this State for an act committed in another state for which the permit holder would be subject to discipline for an act committed in the other state. The Board shall be required to investigate any complaint made by the board of accountancy of another state.
(c) Practice within this State by individuals who qualify for the practice privilege under this section shall not obligate a firm that does not maintain an office in this State to obtain a firm permit under § 111 of this title.
