California Sales Tax for Amazon Sellers

California sales tax for Amazon sellers: the short answer

Marketplace facilitator status: California has had marketplace facilitator (MF) law in effect since 2019. California implemented marketplace facilitator law on October 1, 2019, requiring marketplaces collecting $500K+ annually in California sales to collect on behalf of all third-party sellers.

What this means for you as an Indian FBA seller: for all your Amazon US sales delivered to California customers, Amazon collects the appropriate California sales tax (state + applicable local) and remits to the state directly. You see the line items in your Seller Central report. You do not need to register, collect, or remit California sales tax on Amazon sales.

California sales tax rates

California has a 7.25% statewide base rate, the highest base rate in the US. Local add-ons (county and city) push the effective rate to 10.25% in cities like Los Angeles and Long Beach. Amazon computes the customer-specific rate based on shipping address automatically.

FBA fulfillment centers in California

California has the largest concentration of Amazon FBA fulfillment centers in the US: 12+ FCs across the LA/Long Beach area (LAX9, LGB3, LGB4, ONT2, ONT5, ONT6, ONT8, ONT9, RIV3, RIV6, RIV7, SBD1, SBD2, XLX7), plus Bay Area FCs (OAK3, OAK4, SCK4, SCK6). California FBA inventory ships to all 50 states.

Marketplace facilitator rules: when you DO have California obligations

Three scenarios where Amazon\'s MF coverage doesn\'t apply to you:

1. Selling outside Amazon: if you sell on your own Shopify store, eBay (not always MF), or wholesale to California-based B2B buyers, you may have direct obligations once you cross the economic nexus threshold of $500K.
2. Physical presence: if your LLC has a California-based employee, office, or owned warehouse, that triggers physical nexus. California sales tax registration is required regardless of channel.
3. Owned property & income tax: physical presence may also trigger California state income tax obligations on the portion of profit attributable to the state.

If you do need to register

If one of the above applies, registration is via California Department of Tax and Fee Administration (CDTFA) at cdtfa.ca.gov. The process typically takes 7-14 business days and requires your EIN, LLC details, and operating-history information. Filing frequency depends on volume - monthly, quarterly, or annually.

California-specific FBA notes

• California has the most-aggressive state tax authority. Cross-channel sellers (Amazon + Shopify) should err on the side of registering even if just at threshold.
• California enforces sales tax on shipping when the shipping is not separately stated - Amazon handles this correctly.
• San Diego FCs are not California FBA inventory - they are warehouse-of-record under a different state pattern (Mexico FBA).
• No exemption for textiles, clothing, or food on Amazon (different from some states like PA or MN).

Common questions

Does inventory at a California FBA center create nexus?

Historically yes (physical presence). Post-MF laws, this distinction is largely moot for sales tax - Amazon collects regardless. For state income tax, inventory presence creates a weak nexus that California generally does not pursue aggressively against foreign-owned LLCs whose only state contact is FBA inventory.

Do I need a California seller\'s permit for Amazon FBA only?

No, for Amazon FBA-only operations. California\'s MF law has Amazon as the registered remitter. You don\'t need your own permit unless you sell directly via other channels above threshold.

What about returns processed in California?

Amazon\'s MF remittance covers full refund flows. The sales tax originally collected gets refunded automatically when the order refunds. No separate filing required on your part.
