Cal. Business and Professions Code § 2988

A licensed psychologist who for reasons, including, but not limited to, retirement, ill health, or absence from the state, is not engaged in the practice of psychology, may apply to the board to request that their license be placed on an inactive status. A licensed psychologist who holds an inactive license shall pay a biennial renewal fee, fixed by the board, of two hundred twenty-one dollars ($221). The board may adopt regulations to set the fee at a higher amount, up to a maximum of four hundred dollars ($400). A psychologist holding an inactive license shall be exempt from continuing education requirements specified in Section 2915, but shall otherwise be subject to this chapter and shall not engage in the practice of psychology in this state. Licensees on inactive status who have not committed any acts or crimes constituting grounds for denial of licensure and have completed the continuing education requirements specified in Section 2915 may, upon their request, have their license to practice psychology placed on active status.
