Approved by California's voters in November 2004 and enacted in January 2005, the Mental Health Services Act (MHSA) will expand mental health services for children, adults and seniors in the state, using programs that have proven to be effective. By taxing incomes over $1 million at 1 percent, the MHSA will raise up to $800 million or more each year in state funds. With increased federal funds, the amount of new money for care for people with mental illness is expected to exceed $1 billion per year.
