Accountants Professional Liability Insurance in California
California's Board of Accountancy licenses CPAs and registers firms, with peer review expected for firms performing attest work, and California is notable among states for not having adopted full no-notice mobility, meaning out-of-state CPAs should confirm current practice-privilege requirements before assuming they can serve California clients the same way they would in a typical mobility state. California's high-income, multi-state client base and its own complex state tax rules add further exposure beyond the federal return.

Board registration and peer review
The California Board of Accountancy licenses individual CPAs and registers firms providing attest services, with peer review expected on the applicable cycle for firms that perform that work. California's firm registration and continuing education requirements are generally considered more detailed than many other states', and firms should treat each renewal cycle as an opportunity to confirm nothing has changed rather than assuming a prior year's process still applies.
Mobility practice requires extra confirmation in California
Unlike most states that have adopted broad no-notice mobility, California has historically maintained its own practice-privilege framework with conditions that can differ from the standard mobility model used elsewhere, so an out-of-state CPA planning to serve a California client should confirm current requirements with the California board rather than assuming the same mobility rules that apply in other states carry over automatically.
High-income, multi-state client complexity
California's large population of high-income individuals and technology-sector equity compensation, combined with the state's own complex tax rules that often diverge from federal treatment, means an error in state conformity or equity compensation reporting can generate a sizable claim. Firms serving clients who split time between California and a no-income-tax state also face elevated residency-dispute exposure given California's active enforcement in that area.
