Cal. GOV § 927.11

(a) Except in the case of a contract with a resource conservation district, a certified small business, a nonprofit organization, or a nonprofit public benefit corporation, if an invoice from a business under a contract with the Department of Forestry and Fire Protection would become subject to late payment penalties during the peak fire protection staffing period, as determined by the Director of Forestry and Fire Protection, or their designee, then the required payment approval date shall be extended by 30 calendar days.

(b) No nonprofit public benefit corporation shall be eligible for a late payment penalty if a state agency fails to make timely payment because no Budget Act has been enacted.

(A) A resource conservation district.

(B) A certified small business.

(C) A nonprofit organization.

(D) A nonprofit public benefit corporation.

(E) A small business or nonprofit organization that provides services or equipment under the Medi-Cal program.

(2) A suspension pursuant to this subdivision shall remain in effect until the Director of Finance determines that the suspended late payment penalty provisions should be reinstated.

(d) Except as provided in subdivision (b), in the event a state agency fails to make timely payment because no Budget Act has been enacted, penalties shall continue to accrue until the time that the invoice is paid.
