Rev. & Tax. Code, § 13220

(a) Every person subject to this part shall file with the Franchise Tax Board a return prescribed by the board on or before the first day of the third month following the close of the calendar quarter during which a taxable insurance contract took effect or was renewed.

(b) In accordance with forms and instructions, the tax, penalties, and interest imposed by this part shall be administered and enforced by the Franchise Tax Board as though they are taxes imposed under Part 10 (commencing with Section 17001). Part 10 (commencing with Section 17001), Part 10.2 (commencing with Section 18401), or any other applicable law shall apply for this purpose in the same manner and with the same force and effect as if the language of Part 10 (commencing with Section 17001), Part 10.2 (commencing with Section 18401), or the other applicable law is incorporated in full into this part, except to the extent that the provision is either inconsistent with a provision of this part, is not relevant to this part, or is otherwise provided for under this part.

(c) The following penalties shall apply, in lieu of those penalties provided under Part 10.2 (commencing with Section 18401):

(1) A penalty of 10 percent of the amount of the payment due is imposed upon any person who fails to make the necessary payment within the time required.

(2) For any part of a payment required that was not made within the time required by law, when the nonpayment or late payment was due to fraud on the part of the taxpayer, a penalty of 25 percent of the amount unpaid shall be added thereto, in addition to all other penalties otherwise imposed.

(d) (1) Except as provided in paragraph (2), interest shall be allowed and paid on any refund provided under paragraph (2) of subdivision (a) of Section 13210 from the date the claim for refund is filed. No interest shall be allowed or paid on amounts credited to succeeding calendar quarters as provided under paragraph (2) of subdivision (a) of Section 13210.

(2) If an amount refunded as provided under paragraph (2) of subdivision (a) of Section 13210 within 120 days after a claim or return is filed, or within 120 days after the last date for filing the tax return, whichever is later, no interest shall be allowed on the amount of the refund.

(e) The period of limitation for allowing or making refunds or credits as provided under paragraph (2) of subdivision (a) of Section 13210 shall be the period of limitations for allowing or making refunds or credits of overpayments under Part 10.2 (commencing with Section 18401), except that the “date of cancellation or reduction of premium” shall be substituted for “date of overpayment.”
