This guide is limited to California and uses current California Department of Tax and Fee Administration resources. It does not describe the rules of another state and is not a tax calculation for a specific transaction.
Confirm the seller's registration duty, the type and location of the sale, the current state and district rates, exemption evidence, and marketplace responsibilities before adding tax to an invoice. Use CDTFA guidance or qualified advice when the facts are uncertain.
Confirm the California registration duty
A seller should determine whether it must hold a California seller's permit or Certificate of Registration—Use Tax before collecting tax reimbursement. Physical presence, sales delivered into California, current economic-nexus rules, and the type of activity can affect that decision.
Marketplace sales need separate review. CDTFA guidance explains when a marketplace facilitator collects tax and how a marketplace seller may still need to register and report sales. Keep the permit, marketplace reports, and the basis for the registration decision with the tax records.
- Review California physical presence
- Check CDTFA's current economic-nexus rules
- Identify marketplace-facilitated sales
- Maintain the correct permit or registration
Classify the California sale and purchaser
Determine how California treats each product, service, digital item, bundled charge, delivery charge, and other component. Do not apply one tax setting to every line merely because part of the transaction is taxable.
For a resale or other exempt transaction, obtain and retain the certificate or evidence required by California rules. Review whether it is timely, complete, and applicable to the purchaser and property rather than relying only on a written request not to charge tax.
- Classify each line item
- Review bundled and delivery charges
- Verify California exemption evidence
- Preserve resale certificates and support
Calculate and disclose the California tax
Use the location rules and current state, county, city, and district rates that apply to the transaction date. Confirm the California delivery or business location used in the calculation and keep enough detail to reproduce the rate.
California allows sales tax reimbursement to be listed separately on a receipt or invoice. When it is included in the displayed price instead, the purchaser must be informed that tax is included. Show the taxable amount, rate or calculation, reimbursement, and total consistently.
- Confirm the applicable California location
- Use the current combined rate
- State whether tax is added or included
- Keep the rate and calculation evidence
Report and reconcile California sales tax
Record collected tax reimbursement separately from sales revenue. Reconcile invoices and payments to taxable sales, exempt sales, returns, credits, marketplace-facilitated sales, and the amounts reported to CDTFA.
File and pay on the schedule assigned to the account and preserve the return, payment evidence, invoices, exemption documents, and marketplace statements. Correct invoice or filing errors through the applicable CDTFA process rather than changing an issued record without a trace.
- Separate tax reimbursement from revenue
- Reconcile returns and exemptions
- Account for marketplace reports
- Preserve filings and payment evidence

Not necessarily. District rates and location rules can change the combined rate. Verify the applicable California location and transaction date.
