(a) When license fees are incidentally collected in connection with regulatory activities of some agency or department of the state government other than the Department of Revenue and such fees could be collected more economically by the regulatory agency or department than by the Department of Revenue, the commissioner may delegate by executive order approved by the Governor the collection of the license fees to the state official responsible for administering the regulatory activities.

(b) No delegation pursuant to subsection (a) of this Code section shall extend beyond the term of office of the commissioner or of the officer to whom the collection of fees is delegated by the commissioner.

(c) Except as otherwise expressly provided by law, no other department of the state government may employ any person or persons to collect any fees, licenses, or taxes or to inspect for the purpose of collecting such fees, licenses, or taxes, except when the authority to collect the licenses, fees, or taxes has been expressly delegated to the other department by the commissioner under the terms of this Code section.

(d) In any case in which the collection of any tax or license fee is delegated as provided in this Code section, the commissioner is charged with the duty of retaining supervisory authority over such activity. In any case in which the commissioner finds that a delegation should be revoked, modified, or transferred to another department or other departments, the commissioner, by executive order approved by the Governor, may make the revocation, modification, or transfer.

(e) This chapter shall not in any way affect the collection and administration activities of those regulatory, professional, or vocational bodies or boards operated under the division director of the professional licensing boards division appointed by the Secretary of State under Code Section 43-1-2 as provided by law or of those other regulatory bodies where a major portion of the license fees is collected by mail.
