Existing law allows taxpayers, until January 1, 2025, to designate on their personal income tax return that a specified amount in excess of their personal income tax liability be contributed to the California Alzheimer's Disease and Related Dementia Research Voluntary Tax Contribution Fund, which is a continuously appropriated fund, to be allocated to, among others, the State Department of Public Health to support eligible programs awarded grants under selection criteria established by the State Department of Public Health Alzheimer's Disease Program. This bill would extend the operation of these provisions to January 1, 2032, unless the minimum contribution amount of $250,000 is not met, as specified. By extending the operation of a continuously appropriated fund, the bill would make an appropriation.
