​​​​​​​​​​​​​​​​​​​​​​​​​MHSA Fiscal Oversight

Back to MHSA Webpage

DHCS is responsible for overseeing the use of Mental Health Services Act (MHSA) revenue and expenditures. This is done by reviewing expenditure reports and conducting onsite financial audits. DHCS rev​iews county MHSA Annual Revenue and Expenditure Reports on an annual basis to determine consistency of expenditures with county planning documents, ensure reporting of interest, and to review prudent reserve levels. Upon review of county Annual Revenue and Expenditure Reports, DHCS is also responsible for calculating and managing the amount of Mental Health Service Funds subject to reversion.​​

Annual Revenue & Expenditure Report   

Per Welfare and Institutions Code (WIC), Section 5899(c), counties must submit a completed Annual Revenue Expenditure Report (ARER) to DHCS by  January 31st. The purpose of the ARER is to identify Mental Health Services Act fund expenditures, identify interest earned and unspent funds, and determine reversion amounts.

Beginning with FY 20-21, Counties are required to complete and submit the ARER through the Enterprise Cost Reporting System (ECRS). If you need access to ECRS or if you need a copy of the ECRS User Manual, please send an email to mhsa@dhcs.ca.gov.

​​Pru​dent Reserve        

Per WIC 5847(b)(7), counties are required to establish and maintain a prudent reserve (PR) to ensure children, adults, and seniors can continue receiving services at current levels in the event of an economic downturn. The Prudent Reserve is funded with monies allocated to the Community Services and Supports component and cannot exceed 33% of a county's average distribution for the previous five years.

Per 5892 (b)(7), counties are required to assess and certify their local prudent reserve every 5 years, beginning in FY 17-18.

Per the California Code of Regulations (CCR) 3420.30 (f) counties may reassess the Prudent Reserve funding level more frequently at the county level, which may allow for a new Prudent Reserve maximum level, based on the most recent assessment. Counties choosing to reassess the prudent reserve funding level must submit a DHCS 1819: PR Certification Form.
