California Dropshipping Sales Tax Guide — 2026

Dropshipping into California raises three distinct tax questions. First, you (the retailer) have to collect and remit California sales tax on your retail sales if you exceed $500,000. Second, your dropship supplier may charge YOU sales tax on the wholesale invoice if they have California nexus and you can't present a valid resale certificate. Third, the marketplace (if any) handles its own tax on facilitated transactions.

California applies 7.25% as the base state rate; local add-ons average 1.74%.

• If you have a California sales tax permit, you can usually issue your dropshipper a CA resale certificate to avoid being charged sales tax on the wholesale invoice.
• Some states (notably California, Florida, Massachusetts, Tennessee, and a few others) require the buyer to hold an IN-STATE registration before issuing a resale certificate — a home-state certificate isn't enough.
• Streamlined Sales Tax (SST) states accept the uniform Multistate Certificate; others have their own forms.

• Treating your dropshipper's nexus as if it obligates them to collect from the end customer — no, they invoice you at wholesale; you invoice the customer at retail. Only the retail transaction is subject to collection duty.
• Forgetting that your retail revenue into California still counts toward the economic nexus threshold, independent of the dropshipping arrangement.
• Not keeping resale certificates on file — your supplier will charge you tax (and you'll have already collected from the customer), eroding margin.

California sales tax nexus and economic nexus threshold: CDTFA guidance says remote retailers must register and collect California use tax when total combined sales of tangible personal property for delivery into California exceed $500,000 during the preceding or current calendar year. California uses a sales-only threshold — no transaction-count test. AB 147 replaced the earlier $100,000/200-transaction Wayfair threshold with the current $500,000 standard, and related-person sales count toward the threshold. CDTFA marketplace guidance says sellers include both direct California sales and marketplace-facilitated sales when testing the $500,000 threshold, but sellers whose California sales are entirely facilitated by registered marketplace facilitators may not need separate registration for those marketplace transactions. Direct-to-consumer sales outside a marketplace remain the seller's own collection responsibility once California nexus is met.
