California

California state tax filings.

Which agencies California uses, which forms they take, and what California does differently. Every entry carries the date it was checked against the agency's own material.

Who you deal with in California

California Employment Development Department

One account covering Personal Income Tax withholding, Unemployment Insurance, Employment Training Tax, and State Disability Insurance

e-Services for Business

California Department of Tax and Fee Administration

Publishes resale certificate rules (Publication 103, Regulation 1668) and the CDTFA-230 template. Does not issue or furnish completed resale certificates; purchasers complete them and sellers retain them. Also registers sellers for a seller's permit, which most buyers need before issuing certificates.

CDTFA online services (seller's permit registration); forms/publications for CDTFA-230

CDTFA Out-of-State Office

Questions from retailers outside California about whether they have to register, and the Out-of-State Voluntary Disclosure Program

CDTFA online registration

3 separate agencies, on 3 separate systems. Doing something with one does nothing to the others.

What California does differently

  • The 10-day rule. Your final return, wage report, and payment are due within 10 days of the last wage paid, not on the normal quarterly schedule. Nothing about the regular filing calendar warns you about this, and a business winding down is rarely watching for it.
  • The form asks where your leftover inventory went, and every answer has a consequence. Section II gives you the options: sold and reported on the final return, retained, included in an audit, donated, sold for resale with the purchaser's account number, or other. Retained means use tax. Sold for resale means the buyer's permit number had better be real. This is not a box to tick quickly.
  • Two clocks running against each other. You have 15 days to register and the EDD can take ten business days to issue the number. Leaving the registration until day fourteen means the account number arrives well after the payroll it was needed for.
  • Two registrations share one conversation. A seller's permit and a Certificate of Registration-Use Tax are not the same thing, and which you need depends on whether you are engaged in business in California or selling in from outside. Almost everything published about registering in California describes the seller's permit, so a remote seller reads about a permit that may not be the one they need.
  • People confuse the seller's permit with a 'resale certificate' or 'resale number.' CDTFA registers the permit; the certificate is a separate document you fill out for suppliers.

Resale certificate in California

California issues no resale certificate like Florida's DR-13. We prepare a valid CDTFA-230 with the required elements so suppliers can accept it in good faith.
