Cal. Rev. & Tax. Code § 30191

If the board finds that a person’s failure to make payment by an appropriate electronic funds transfer in accordance with board procedures is due to reasonable cause and circumstances beyond the person’s control, and occurred notwithstanding the exercise of ordinary care and in the absence of willful neglect, that person shall be relieved of the penalty provided in subdivision (e) of Section 30190. Any person seeking to be relieved of the penalty shall file with the board a statement under penalty of perjury setting forth the facts upon which he or she bases his or her claim for relief.
