(a) Permits to engage in the practice of public accountancy in this state shall be issued by the board only to holders of the certificate of certified public accountant issued under this chapter and to those partnerships, corporations, and other persons who, upon application approved by the board, are registered with the board under this chapter. Notwithstanding any other law, the board may register an entity organized and authorized to practice public accountancy under the laws of another state for the purpose of allowing that entity to satisfy the registration requirement set forth in Section 5096.12, if (1) the certified public accountants providing services in California qualify for the practice privilege, and (2) the entity satisfies all other requirements to register in this state, other than its form of legal organization.

(b) All applicants for registration shall furnish satisfactory evidence that the applicant is entitled to registration and shall pay the fee as provided in Article 8 (commencing with Section 5130). Every partnership, corporation, and other person to whom a permit is issued shall, in addition to any other fee that may be payable, pay the initial permit fee provided in Article 8 (commencing with Section 5130).

(c) Each applicant who has a valid email address shall report to the board that email address at the time of application or registration.

(d) Each partnership, corporation, and other person issued a permit by the board to practice as a certified public accountant or as a public accountant shall be furnished with a suitable certificate evidencing that registration.
