Overview of Sales and Use Tax in Fullerton

Retail sales in Fullerton are subject to California state sales and use tax plus any district transactions and use taxes that apply within the city limits. The California Department of Tax and Fee Administration (CDTFA) administers collection and remittance for state and most local district taxes and issues sellers permits and filing guidance for retailers [1]. Retailers must determine the correct tax rate for each transaction based on location of sale, delivery destination, and any applicable exemptions.

Registration and Filing

  • Obtain a seller's permit from the CDTFA before making sales; this permit authorizes collection of sales tax and registration details are on the CDTFA site [2].
  • Register for the correct filing frequency (monthly, quarterly, annual) as assigned by CDTFA when you apply for a permit.
  • Collect the combined tax rate (state plus any Fullerton district tax) from customers at point of sale.
  • Keep accurate records of sales, exemptions, resale certificates, and deliveries to substantiate returns and audits.
Apply for a seller's permit before opening for sales.
