Cal. Bus. & Prof. Code § 7145.5

(a) The registrar may refuse to issue, reinstate, reactivate, or renew a license or may suspend a license for the failure of a licensee to resolve all outstanding final liabilities, which include taxes, additions to tax, penalties, interest, and any fees that may be assessed by the board, the Department of Industrial Relations, the Employment Development Department, the Franchise Tax Board, or the State Board of Equalization.
1. (1) Until the debts covered by this section are satisfied, the qualifying person and any other personnel of record named on a license that has been suspended under this section shall be prohibited from serving in any capacity that is subject to licensure under this chapter, but shall be permitted to act in the capacity of a nonsupervising bona fide employee.
2. (2) The license of any other renewable licensed entity with any of the same personnel of record that have been assessed an outstanding liability covered by this section shall be suspended until the debt has been satisfied or until the same personnel of record disassociate themselves from the renewable licensed entity.
(b) The refusal to issue a license or the suspension of a license as provided by this section shall be applicable only if the registrar has mailed a notice preliminary to the refusal or suspension that indicates that the license will be refused or suspended by a date certain. This preliminary notice shall be mailed to the licensee at least 60 days before the date certain.
(c) In the case of outstanding final liabilities assessed by the Franchise Tax Board, this section shall be operative within 60 days after the Contractors State License Board has provided the Franchise Tax Board with the information required under Section 30, relating to licensing information that includes the federal employer identification number, individual taxpayer identification number, or social security number.
(d) All versions of the application for a contractor’s license shall include, as part of the application, an authorization by the applicant, in the form and manner mutually agreeable to the Franchise Tax Board and the board, for the Franchise Tax Board to disclose the tax information that is required for the registrar to administer this section. The Franchise Tax Board may from time to time audit these authorizations.
(e) In the case of outstanding final liabilities assessed by the State Board of Equalization, this section shall not apply to any outstanding final liability if the licensee has entered into an installment payment agreement for that liability with the State Board of Equalization and is in compliance with the terms of that agreement.
