Cal. Rev. & Tax. Code § 19581

In enacting the California Personal Income Tax Fairness, Simplification, and Conformity Act of 1987, the Legislature finds and declares that for most taxpayers in most ordinary circumstances, the burden of preparing tax returns could be greatly reduced by the availability of state tax forms which would allow taxpayers to copy numbers from the federal return, make simple adjustments, look up the tax in published tax tables, subtract state tax credits, and either pay the amount due or file for a refund.
