With nearly 40 million residents, California represents the largest state economy in the U.S. — and one of the most active consumer markets for e-commerce. For many online sellers, California is consistently among their top five revenue-generating states.
California's economic nexus threshold of $500,000 means many large online sellers already have exposure. But the threshold is not the only trigger — physical presence through employees, contractors, or FBA inventory can create nexus at any revenue level.
California's sales tax system is also notably complex. District taxes — additional local rates imposed by cities, counties, and special districts — mean that the rate a seller must charge varies by delivery destination within the state. California has some of the highest combined sales tax rates in the country.
California economic nexus applies when your cumulative sales of tangible personal property into California exceed $500,000 during the prior or current calendar year.
California has numerous Amazon FBA fulfillment centers. Inventory stored in any California warehouse likely creates physical nexus immediately — often the more immediate trigger than economic nexus for many FBA sellers.
Any employee working from California — including fully remote employees — creates physical nexus. California aggressively enforces employee-based nexus and routinely audits businesses with California remote workers.
Independent contractors or sales representatives who regularly solicit business in California on your behalf may also create nexus. The analysis depends on the nature of their activities.
Sales and use tax in California is administered by the California Department of Tax and Fee Administration (CDTFA).
