Not professional advice. Nothing on this site is legal, tax, accounting, or investment advice. Tax laws are complex and change; regulations implementing SB 122 (CDTFA) are still pending. The decision tool encodes public statutory text and professional summaries to help you self-answer a question — it is not a substitute for advice from a qualified tax professional or the California Department of Tax and Fee Administration. Verify every conclusion before relying on it.
