California taxes through the California Department of Tax and Fee Administration (CDTFA) at a 7.25% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $500,000 in sales. Filing runs quarterly by default, with prepayments at higher volumes. For e-commerce & online sellers, that combination is what decides how much of your month-end is bookkeeping and how much is compliance.
Employer registration runs through the California Employment Development Department (EDD), and the entity is registered with the California Secretary of State. Highest statewide base rate in the country, and district taxes stack on top. LLCs also owe the $800 annual franchise tax to the Franchise Tax Board regardless of income.

Sales tax nexus in California
Economic nexus in California is $500,000 in sales. For e-commerce & online sellers, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the California Department of Tax and Fee Administration (CDTFA) and begin collecting. We track your California sales against it and tell you before you cross, not after.
Marketplace sales vs. your own channels in California
Marketplace facilitator rules mean large platforms generally collect and remit California tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the California Department of Tax and Fee Administration (CDTFA) return match reality.
California rates and sourcing
The California statewide base rate is 7.25%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
Filing cadence in California
California assigns filing frequency by liability — quarterly by default, with prepayments at higher volumes. California does not offer an annual bracket, so even low-volume sellers file at least quarterly and the account has to stay current year-round.
