Retailer Duties and When to Register

Retailers doing business in Stockton generally must register with the California Department of Tax and Fee Administration (CDTFA) for a seller's permit and with the City of Stockton for any required local business tax or license. Key duties include collecting sales tax on taxable sales, issuing resale certificates to qualifying buyers, and keeping adequate records to substantiate exempt sales.

  • Register for a seller's permit with the CDTFA and obtain the City business tax certificate.
  • Collect the correct combined sales and use tax rate on taxable transactions.
  • Retain sales invoices, resale certificates, and exemption documentation for the statutory retention period.
  • File periodic returns and remit payments by the due dates assigned by CDTFA.
If you sell online, determine nexus and collect tax where you have sufficient economic presence.
