According to the California State Department of Mental Health:
The passage of Proposition 63 (now known as the Mental Health Services Act or MHSA) in November 2004, provides the first opportunity in many years for the Department of Mental Health (DMH) to provide increased funding, personnel and other resources to support county mental health programs and monitor progress toward statewide goals for children, transition age youth, adults, older adults and families. The Act addresses a broad continuum of prevention, early intervention and service needs and the necessary infrastructure, technology and training elements that will effectively support this system.
This Act imposes a 1% income tax on personal income in excess of $1 million. Statewide, the Act was projected to generate approximately $254 million in fiscal year 2004-05, $683 million in 2005-06 and increasing amounts thereafter. Much of the funding will be provided to county mental health programs to fund programs consistent with their local plans. Any uncommitted funds during FY 2005-06 will be used to establish county prudent reserve accounts as required by the Act.
