Rev. & Tax. Code, § 19180

(a) In any proceeding involving the issue of whether or not any person is liable for a penalty under Section 19177, 19178, or 19179, the burden of proof with respect to that issue shall be on the Franchise Tax Board.

(b) Sections 19041 to 19049, inclusive, (relating to deficiency procedures) shall not apply with respect to the assessment or collection of the penalties provided by Section 19177, 19178, or 19179.

(c) (1) If, within 30 days after the day on which notice and demand of any penalty under Section 19177 or 19178 is made against any person, that person pays an amount which is not less than 15 percent of the amount of that penalty and files a claim for refund of the amount so paid, no levy or proceeding in court for the collection of the remainder of that penalty shall be made, begun, or prosecuted until the final resolution of a proceeding begun as provided in paragraph (2). Notwithstanding Section 19381, the beginning of that proceeding or levy during the time that prohibition is in force may be enjoined by a proceeding in the superior court. Nothing in this paragraph shall be construed to prohibit any counterclaim for the remainder of that penalty in a proceeding begun as provided in paragraph (2).

(2) If, within 30 days after the day on which the claim for refund of any partial payment of any penalty under Section 19177 or 19178 is denied (or, if earlier, within 30 days after the expiration of six months after the day on which a claim for refund was filed), the person fails to begin a proceeding in the superior court for the determination of the liability for that penalty, paragraph (1) shall cease to apply with respect to that penalty, effective on the day following the close of the applicable 30-day period referred to in this paragraph.

(3) The running of the period of limitations provided in Section 19371 on the collection by levy or by a proceeding in court in respect of any penalty described in paragraph (1) shall be suspended for the period during which the Franchise Tax Board is prohibited from collecting by levy or a proceeding in court.
