What Constitutes Doing Business in California?
Key Takeaway
“Doing business” in California under RTC §23101 captures four triggers: (1) actively engaging in transactions for profit in CA; (2) CA sales exceeding $711,538 (2024, indexed); (3) CA real or tangible personal property exceeding $71,154; or (4) CA compensation paid exceeding $71,154. The short version is that crossing any single threshold creates the doing-business status, which triggers the $800 minimum franchise tax plus regular income tax. In our experience, many out-of-state businesses unknowingly cross the sales threshold and owe back taxes.1

Dealing with Multistate Tax Exposure?
Multistate obligations don’t announce themselves — most businesses accumulate sales tax, income tax, or payroll tax exposure in other states without realizing it until they’re contacted or audited. If you’re selling across state lines, have remote employees, or aren’t sure where your business has nexus, a brief review can identify where you have exposure and what to do about it.

Frequently Asked Questions
What is "doing business" in CA?
Per RTC §23101 — actively engaging in transactions for profit in CA, OR crossing sales ($711K), property ($71K), or payroll ($71K) thresholds. Any single trigger creates status.
What is the $800 minimum tax?
Annual minimum franchise tax. Applies to CA-formed or doing-business entities. Due even with no income. First-year exemption for corporations; LLC pays first year.
Does forming in NV/DE avoid CA?
No. Formation state irrelevant if doing business in CA. CA taxes based on CA activity regardless of formation.
Does FBA inventory create doing business?
Yes if threshold met. CA FBA inventory counts as CA property. Over $71K threshold triggers doing-business status.
Remote CA employee creates doing business?
Payroll threshold is $71K. Over that, yes. Under, facts-specific. Often also creates other nexus types.
Are thresholds annual?
Yes. Measured annually. Crossing in single year triggers that year. Fact-specific by year.
What if CA sales under $711K?
Economic threshold not met. But physical / property / payroll triggers still apply. Active engagement test separate.
Is $800 min creditable?
Against regular income tax: yes. Taxpayer pays greater of regular tax or $800. Not refundable if regular tax lower.
What about short periods?
$800 still applies for any year with doing-business status. Pro-rating generally not available.
