An accountancy corporation shall not do or fail to do any act the doing of which or the failure to do which would constitute unprofessional conduct under any statute, rule or regulation now or hereafter in effect. In the conduct of its practice, it shall observe and be bound by such statutes, rules and regulations to the same extent as a person holding a permit under Section 5070 of this code. The board shall have the same powers of suspension, revocation and discipline against an accountancy corporation as are now or hereafter authorized by Section 5100 of this code, or by any other similar statute against individual licensees, provided, however, that proceedings against an accountancy corporation shall be conducted in accordance with Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code, and the board shall have all the powers granted therein.
