Under California Revenue & Taxation Code § 23101, an out-of-state entity has "doing business" nexus in California if it has a physical presence (including remote W-2 workers or leased offices) or meets California factor-based economic thresholds ($757,070 sales, $75,707 payroll, or $75,707 property — latest FTB-published 2025 figures; verify 2026 before filing). Meeting any of these makes you a California taxpayer owing at least the $800 annual tax; a physical presence such as an office or employees usually also requires registering with the Secretary of State.
