Cal. Rev. & Tax. Code § 11253

(a) The board may, in its discretion, enter into a written installment payment agreement with a person for the payment of any taxes due, together with interest thereon and any applicable penalties, in installments over an agreed period. With mutual consent, the board and the taxpayer may alter or modify the agreement.
(b) Upon failure of a person to fully comply with the terms of an installment payment agreement with the board, the board may terminate the agreement by mailing a notice of termination to the person. The notice shall include an explanation of the basis for the termination and inform the person of his or her right to request an administrative review of the termination. Fifteen days after the mailing of the notice, the installment payment agreement shall be void, and the total amount of the tax, interest, and penalties due shall be immediately payable.
(c) The board shall establish procedures for an administrative review for persons requesting that review whose installment payment agreements are terminated under subdivision (b). The collection of taxes, interest, and penalties that are the subject of the terminated installment payment agreement may not be stayed during this administrative review process.
(d) The notice requirement in subdivision (b) shall not apply to any case where the board finds collection of the tax to be in jeopardy.
Except in the case of fraud, if an installment payment agreement is entered into within 45 days from the due date of the tax bill, and the person complies with the terms of the installment payment agreement, the board shall relieve the penalty imposed pursuant to Section 11341.
