California Business And Professions Code Section 5040

The Legislature finds and declares that it is important to inform taxpayers that they may make voluntary contributions to certain funds or programs, as provided on the state income tax return. The Legislature further finds and declares that many taxpayers remain unaware of the voluntary contribution check-offs on the state income tax return. Therefore, it is the intent of the Legislature to encourage all persons who prepare state income tax returns, including accountants, to inform their clients in writing, prior to the completion of any state income tax return, that they may make a contribution to any voluntary contribution check-off on the state income tax return if they so choose.
