California Code, Business and Professions Code - BPC § 6163

(a) Each law corporation shall file with the State Bar annually and at such other times as the State Bar may require a report containing such information pertaining to qualification and compliance with the statutes, rules, and regulations referred to in Section 6127.5 as the State Bar may determine.  The fee for filing such a report shall be fixed by the State Bar.  All reports shall be signed and verified by an officer of the corporation.  The State Bar may fix a penalty for the late filing of an annual report in an amount not to exceed double the amount of the applicable filing fee and may also fix the date upon which the penalty shall attach if the report has not been filed and the fee paid prior to that date.  The date upon which the penalty shall attach shall be not less than 31 days following the date fixed for filing the report.  The filing of the annual report together with the filing fee and any penalty due for late filing constitutes the annual renewal of the certificate of registration.  The fee fixed by the board for the filing of the annual report and any penalty due for late filing constitutes the fee required by Section 6161.1 for renewal of the certificate for the year in which the annual report is due to be filed.

(b) The certificate of registration of any law corporation failing to file the annual report, renew its certificate, and pay the fee therefor and any penalty due thereon for late filing, shall be suspended 60 days following written notice of delinquency.  The written notice shall be mailed to the corporation at its current office or other address for State Bar purposes, as shown on the law corporation records of the State Bar.  The suspension shall be ordered by the chief executive officer of the State Bar or his or her designee.

(c) A certificate of registration suspended pursuant to subdivision (b) may be reinstated upon the filing by the law corporation of all delinquent annual reports and payment of all accrued fees and penalties required by this section and Section 6161.1 which are due on the date of the suspension, and any such fees and penalties which become due on or before the date of the reinstatement.
