Income taxes: credits: battery storage system units for solar power systems.

The Personal Income Tax Law and the Corporation Tax Law allow various credits against the taxes imposed by those laws. This bill, under both laws, for taxable years beginning on and after January 1, 2021, and before January 1, 2026, would allow a credit to a taxpayer, except as specified, that purchases a battery storage system unit for a solar energy system, as defined, in an amount equal to 50% of the costs paid or incurred by the taxpayer for that battery storage system unit, not to exceed $5,000 per taxable year, as specified. The bill would allow the credit for only one battery storage system unit per each separate legal parcel of property for which the filing taxpayer has legal ownership in the state. The bill would require the Franchise Tax Board to allow the credit to taxpayers filing for the same legal parcel of property on a first-come-first-served basis, determined by the date the taxpayer's timely filed original tax return is received by the Franchise Tax Board, except as provided. The bill would provide that the board's determination as to the date a return is received and whether a return has been timely filed for purposes of the credit is not reviewable in any administrative or judicial proceeding. Existing law requires any bill authorizing a new tax expenditure to contain, among other things, specific goals, purposes, and objectives that the tax expenditure will achieve, detailed performance indicators, and data collection requirements. This bill would also include additional information required for any bill authorizing a new tax expenditure. This bill would take effect immediately as a tax levy.
