California tangible merchandise delivery threshold.
Local district taxes can raise the total rate above the statewide base.
Facilitators are generally responsible for facilitated sales.
Quick answer for ecommerce sellers.
California economic nexus means that the total combined sales of tangible personal property for delivery in California by a retailer and related persons exceed $500,000 in the preceding or current calendar year. CDTFA states that the threshold includes sales made directly and sales facilitated through a marketplace facilitator's marketplace.
California marketplace facilitator rules generally make registered or required-to-register marketplace facilitators responsible for collecting and paying tax on facilitated retail sales of tangible merchandise for delivery to California purchasers. Sellers with direct California sales may still have registration requirements.
What creates California sales tax nexus?
- Economic nexus: total combined California-delivery sales over $500,000 in the preceding or current calendar year.
- Physical presence: inventory, representatives, property, places of business, or California selling activities can create obligations.
- Marketplace sales: marketplace-facilitated sales count toward the economic nexus threshold.
- Direct sales: marketplace sellers with direct California sales may need registration even if marketplaces collect on facilitated sales.
- District taxes: registered retailers may need to collect district use tax for deliveries into taxing districts.
How California registration fits into the workflow.
Once California is active, save the seller's permit or Certificate of Registration - Use Tax, account number, filing frequency, portal owner, payment method, marketplace status, district tax process, and reviewer assignment. The account notes should show whether the seller has direct sales, marketplace sales, physical presence, economic nexus, or a combination.
Because California includes related persons and marketplace-facilitated sales in threshold review, save threshold support separately from the tax return summary.
Collection, marketplace sales, and district tax.
California collection depends on sales channel, delivery location, registration status, marketplace facilitator role, and district tax obligations. A return packet should preserve total sales, marketplace deductions, direct sales, refunds, and district support.
- Separate direct sales from marketplace-facilitated sales.
- Preserve California delivery destination and district tax support.
- Track taxable, nontaxable, exempt, refunded, and facilitated sales.
- Save marketplace facilitator documentation when tax was collected by the platform.
- Reconcile sales tax collected to return totals before filing.
How to prepare a California filing packet.
- Export exact-period reports: direct orders, marketplace reports, refunds, tax collected, exemptions, and accounting data.
- Confirm threshold: document combined California-delivery sales against the $500,000 rule.
- Map district support: preserve destination and district tax data.
- Separate channels: distinguish marketplace-facilitated and direct merchant-collected sales.
- Review account cadence: confirm filing frequency and due date.
- Archive proof: save source reports, return confirmation, payment receipt, and reviewer notes.
California packets also need enough detail for a reviewer to understand district tax exposure. Keep destination data, marketplace totals, direct-channel totals, refunds, exemption support, and any rate override notes in the same package. A clean California summary should explain not only what tax was collected, but how the seller decided which sales belonged in the California return and which sales were marketplace-facilitated.
For growing ecommerce sellers, review California before a high-volume launch, promotion, or marketplace change. Those events can change the mix of direct and facilitated sales and make year-to-date threshold support harder to reconstruct later.
Risk controls for California.
California risk often comes from ignoring marketplace sales in threshold review, failing to preserve district tax support, or assuming marketplace collection eliminates all registration concerns when direct sales remain.
- Were direct, related-person, and facilitated sales included in threshold review?
- Are direct and marketplace sales separated for filing?
- Does the packet preserve district tax support?
- Are refunds and exemptions documented?
- Was filing proof archived after submission?
