In California, 1 state agency publishes 32 official links for this service. Reviewed requirements cover eligibility (19), deadlines (9), payment methods (9), availability notices (7), appeals (4), documents (3), processing time (2) and appointments (1).

Before you start · 3 things to check
  • Choose personal or business income tax; CDTFA sales tax and IRS federal tax use separate agencies.
  • Check the actual tax year. An extension to file does not automatically extend payment.
  • Use official eligibility checklists and your notice’s deadline; county maps help navigation, not personal tax decisions.
