Economic Nexus Laws by State: California

by TaxJar December 12, 2018


State laws on economic nexus vary and it’s hard to keep up if you’re doing business in multiple states. We’ve done the research for you and here’s all the information you need to know about economic nexus in California.

What is economic nexus in California?

With the recent South Dakota v. Wayfair Supreme Court ruling in favor of South Dakota, states are now free to pursue sales tax from eCommerce businesses who have a “significant presence” in their state.

Significant presence or “nexus” was previously defined as having a physical presence (ex: brick and mortar store, employee, or inventory in a fulfillment center like FBA). But with this recent ruling, now this definition has been expanded to include economic activity in a state as well. This concept of triggering sales tax responsibility because of your economic activity in a state is now referred to as economic nexus.

Most important, this now means that if you pass a state’s economic threshold for total revenue in that state and/or number of transactions in that state, you’re now legally required to register, collect and remit sales tax for that state.

What’s the threshold for economic nexus law in California?

  • State: California 
  • Threshold: Sales of $500,000 in California in the state in the current or last calendar year.
  • Summary: According to state law, remote sellers in California who exceed the $500K gross sales are required to register with the CDTFA, collect sales tax on sales that ship to California, and remit the sales tax to the state.

When did this California law go into effect or is it planned?

April 1, 2019, was when California’s original economic nexus laws took effect, but they evolved as of April 26, 2019, from $100,000 in sales and 200 transactions annually, to $500,000 in sales and no transaction threshold.
