Income tax: health savings accounts: This bill, for taxable years beginning on or after January 1, 2019, would allow a deduction in computing adjusted gross income in connection with health savings accounts in conformity with federal law. In general, the deduction would be an amount equal to the aggregate amount paid in cash during the taxable year by, or on behalf of, an eligible individual, as defined, to a health savings account of that individual, as provided. The bill, for taxable years beginning on or after January 1, 2019, would also provide related conformity to that federal law with respect to the allowance of rollovers from Archer Medical Savings Accounts, health flexible spending arrangements, or health reimbursement accounts to a health savings account, and penalties in connection therewith. The bill would make these provisions operative on the effective date of any budget measure specifically appropriating funds to the Franchise Tax board for its costs to administer these provisions.
