Except as
provided in paragraph (2), Section 6694(a)(1) of the Internal Revenue Code is modified to substitute “$250” for “$1,000.”
(2)
For taxpayers that have a reportable transaction, as defined in Section 6707A(c)(1) of the Internal Revenue Code, with respect to which the requirements of Section 6664(d)(2)(A) of the Internal Revenue Code are not met, any listed transaction, as defined in Section 6707A(c)(2) of the Internal Revenue Code, or a gross misstatement within the meaning of Section 6404(g)(2)(D) of the Internal Revenue Code, paragraph (1) shall not apply.
(c)
Section 6694(c) of the Internal Revenue Code shall not apply and, in lieu thereof, the following shall apply:
(1)
If, within 30 days after the day on which notice and demand of any penalty under Section 6694(a) or 6694(b) of the Internal Revenue Code is made
against any person who is an income tax return preparer, 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 in a proceeding in the superior court.

If, within 30 days after the day on which a claim for refund of any partial payment of any penalty under Section 6694(a) or 6694(b) of the Internal Revenue Code is denied (or, if earlier, within 30 days after the expiration
of six months after the day on which the claim for refund has been filed), the income tax return preparer fails to begin a proceeding in the superior court for the determination of his or her 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.
