Business Bank Account in California
California has the largest banking market of any state, with extensive national bank branch networks, dozens of community banks, and a strong credit union sector. The DFPI supervises state-chartered institutions and publishes a licensee search at dfpi.ca.gov. California's CFDL (SB 1235) requires commercial financing disclosures for offers under $500,000 — relevant context for your lender relationships, not your bank account.

What to look for in a business bank account in California
A business bank account is the foundation of your funding stack. These are the factors that matter most when choosing where to bank.
Monthly fee and minimum balance
Business checking accounts typically charge $0–$30/month, often waivable with a minimum daily balance ($500–$25,000 depending on the bank). Compare the fee waiver threshold against your typical operating balance — some accounts are free at low balances, others require large reserves.
Transaction limits
Many business checking accounts cap free transactions (checks, ACH, teller) at 100–200/month, then charge $0.20–$0.50 per transaction. High-volume businesses (retail, e-commerce) should compare transaction limits carefully.
Cash deposit capability
Digital-first banks (Mercury, Relay, Novo) do not accept cash deposits — use these only if your business has no physical cash revenue. Cash-deposit-heavy businesses (restaurants, retail, laundromats) need a traditional bank with branch or ATM cash-deposit access.
Interest on deposits
Business savings and money market accounts at digital-first banks and some credit unions pay meaningfully higher APY on idle cash than traditional banks. If you maintain a significant cash reserve, compare business savings rates alongside checking fees.
ACH and wire fees
ACH transfers are typically free or low-cost ($0–$1). Domestic wire fees range from $0 (some digital banks) to $25–$40 at traditional banks. International wires run $35–$65 at most banks. If you wire frequently, this cost compounds.
Integration with accounting software
Digital-first banks (Mercury, Relay, Novo) offer native integrations with QuickBooks, Xero, and FreshBooks for automated bank-feed reconciliation. Traditional banks offer this via third-party connectors (Plaid) — the quality varies. If you do your own bookkeeping, account for this time cost.

Business banking in California — common questions
What do I need to open a business bank account in California? +
Most banks require: EIN, California Secretary of State entity documents (Articles of Organization for LLCs, Articles of Incorporation for corporations), government-issued ID for all beneficial owners, and an initial deposit. Some banks also require a signed operating agreement for LLCs.
Who regulates banks in California? +
State-chartered banks are supervised by the California DFPI (dfpi.ca.gov). Federally chartered banks are supervised by the OCC. All FDIC-insured banks are searchable at fdic.gov. The DFPI also licenses fintechs and digital banks operating in California.
Does California's $800 franchise tax affect business banking? +
The $800 minimum franchise tax is a state tax obligation, not a banking fee. It does not affect your bank account directly, but it is a real operating cost that new California business owners should budget for from Day 1.
What is California SB 1235 and does it affect my business account? +
SB 1235 requires commercial financing providers to disclose APR-equivalent terms on offers under $500,000. It applies to lenders and financing companies, not to business bank accounts (which are deposit products, not loans). It is relevant when you apply for a line of credit or term loan through your bank.
What is FDIC insurance? +
FDIC insurance covers deposits up to $250,000 per depositor per FDIC-insured bank per ownership category. For businesses with large cash balances, ask your bank about IntraFi Network (formerly CDARS/ICS) or other deposit-spreading arrangements to extend coverage beyond $250,000.
