If you dropship or buy inventory for resale and a supplier asks for California resale documentation, the form you will usually hear about is the California General Resale Certificate, CDTFA-230.

California is a state to treat carefully. A generic multistate certificate is not always enough, and the standard California certificate generally expects a valid California seller's permit number.

What the California resale certificate does

A resale certificate tells a supplier that you are buying goods for resale, not for your own use. When the certificate is valid for the transaction, the supplier can support treating the sale as a resale sale instead of charging sales tax on the inventory purchase.

In California, CDTFA-230 asks for details such as:

  • The purchaser's seller's permit number.
  • The purchaser's business name and address.
  • The seller's name.
  • A description of the property being purchased.
  • The purchaser's business activity.
  • A signature and date.

Can out-of-state dropshippers use a home-state certificate?

Do not assume a home-state certificate will be enough for California. California's general resale certificate normally requires a California seller's permit number.

There can be limited drop-shipment fact patterns where California's rules need a closer look, especially when suppliers, sellers, and ship-to states differ. CDTFA Publication 103 is the official starting point for California sales-for-resale rules. If your supplier is asking for California documentation, confirm what permit number and form the supplier will accept before sending a generic certificate.
