Cal. Rev. & Tax. Code § 19008

(a) The Franchise Tax Board may, in cases of financial hardship, as determined by the Franchise Tax Board, allow a taxpayer to enter into installment payment agreements with the Franchise Tax Board to make full or partial payment of taxes due, plus applicable interest and penalties over the life of the installment period. Failure by a taxpayer to comply fully with the terms of the installment payment agreement shall render the agreement null and void, unless the Franchise Tax Board determines that the failure was due to a reasonable cause, and the total amount of tax, interest, and all penalties shall be immediately due and payable.

(b) In the case of a liability for tax of an individual under Part 10 (commencing with Section 17001) or this part, the Franchise Tax Board shall enter into an agreement to accept the full payment of the tax in installments if, as of the date the individual offers to enter into the agreement, all of the following apply: (1) The aggregate amount of the liability (determined without regard to interest, penalties, additions to the tax and additional amounts) does not exceed ten thousand dollars ($10,000). (2) The taxpayer (and, if the liability relates to a joint return, the taxpayer’s spouse) has not during any of the preceding five taxable years done any of the following: (A) Failed to file any return of tax imposed under Part 10 (commencing with Section 17001) or this part. (B) Failed to pay any tax required to be shown on the return. (C) Entered into an installment agreement under this section for payment of any tax imposed by Part 10 (commencing with Section 17001) or this part. (3) The Franchise Tax Board determines that the taxpayer is financially unable to pay the liability in full when due, and the taxpayer submits any information as the Franchise Tax Board may require to make this determination. (4) The agreement requires full payment of the liability within three years. (5) The taxpayer agrees to comply with the provisions of this part and Part 10 (commencing with Section 17001) for the period the agreement is in effect.

(c) Except in any case where the Franchise Tax Board finds collection of the tax to which an installment payment agreement relates to be in jeopardy, or there is a mutual consent to terminate, alter, or modify the agreement, the agreement shall not be considered null and void, or otherwise terminated, unless both of the following occur: (1) A notice of termination is provided to the taxpayer not later than 30 days before the date of termination. (2) The notice includes an explanation of why the Franchise Tax Board intends to terminate the agreement.

(d) No levy may be issued on the property or rights to property of any person with respect to any unpaid tax: (1) During the period that an offer by the taxpayer for an installment agreement under this section for payment of the unpaid tax is pending with the Franchise Tax Board. (2) If the offer is rejected by the Franchise Tax Board, during the 30 days thereafter and, if a request for review of the rejection is filed within the 30 days, during the period that the review is pending. (3) During the period that the installment agreement for payment of the unpaid tax is in effect. (4) If the agreement is terminated by the Franchise Tax Board, during the 30 days thereafter (and, if a request for review of the termination is filed within the 30 days, during the period that the review is pending). (5) This subdivision shall not apply with respect to any of the following: (A) Any unpaid tax if either of the following occurs: (i) The taxpayer files a written notice with the Franchise Tax Board that waives the restriction imposed by this subdivision on levy with respect to the tax. (ii) The Franchise Tax Board finds that the collection of that tax is in jeopardy. (B) Any levy that was first issued before the date that the applicable proceeding under this subdivision commenced. (C) At the discretion of the Franchise Tax Board, any unpaid tax for which the taxpayer makes an offer of an installment agreement subsequent to a rejection of an offer of an installment agreement with respect to that unpaid tax (or to any review thereof). (D) The period of limitation under Section 19371 shall be suspended for the period during which the Franchise Tax Board is prohibited under this subdivision from making a levy.

(e) The Taxpayers’ Rights Advocate shall establish procedures for an independent departmental administrative review for the rejection of the offer of an installment payment and for installment payment agreements that are rendered null and void, or otherwise terminated under this section, for taxpayers that request that review. This administrative review shall not be subject to Chapter 4.5 (commencing with Section 11400) of Part 1 of Division 3 of the Government Code. Unless review is requested by the taxpayer within 30 days of the date of rejection of the offer of an installment agreement or termination of the installment agreement, this administrative review shall not stay collection of the tax to which the installment payment agreement relates.

(f) In the case of an agreement entered into by the Franchise Tax Board under subdivision (a) for partial payment of a tax liability, the Franchise Tax Board shall review the agreement at least once every two years.
