Welf. & Inst. Code, § 12306

(a) When enacted, 1991 Realignment Legislation implemented changes to the state and county cost-sharing ratios for services provided under this article. These provisions established the counties’ share of costs for the nonfederal portion of these services at 35 percent, with the state responsible for the remaining 65 percent of these costs. This cost-sharing ratio was the basis for determining the counties’ and the state’s share of costs for these services in the 2017–18 fiscal year.

(b) Beginning in the 2017–18 fiscal year and each fiscal year thereafter, the state and counties shall share the annual cost of providing services under this article as specified in this section.

(c) The county share of cost of providing these services shall be the County IHSS Maintenance of Effort pursuant to Section 12306.16.

(d) (1) Except as provided in paragraph (2), the state shall pay to each county, from the General Fund and any federal funds received under Title XX of the federal Social Security Act available for that purpose, the difference between the actual total cost of providing services under this article that exceeds the county share as specified in subdivision (c).

(2) For services eligible for federal funding pursuant to Title XIX of the federal Social Security Act under the Medi-Cal program, the state shall pay to each county, from the General Fund and any funds available for that purpose the difference between the actual nonfederal cost of providing services under this article that exceeds the county share as specified in subdivision (c).
