Opening an LLC Bank Account in California

The bank account is where an LLC’s separateness shows up in practice. The owner who opens the account the week the LLC is formed, and runs every dollar through it, has an entity a court will respect. The owner who keeps paying business bills from a personal checking account has handed a future plaintiff an argument. This page covers what banks ask for, why, who can sign, and how to run the account so it helps you. It’s part of the good-standing series that starts with my California LLC annual requirements page.

Does a California LLC need its own bank account?

No statute makes you open one, and you should anyway. California’s LLC statute treats the LLC as an entity distinct from its members (Corp. Code § 17701.04(a)). The account is how you show that separateness in practice.

Courts decide whether to disregard an LLC under the alter ego doctrine, which applies to LLC members the same way it applies to corporate shareholders (§ 17703.04(b)). The factors courts weigh include commingling of funds and other assets, failure to segregate funds, and treating the entity’s assets as the owner’s own (Associated Vendors, Inc. v. Oakland Meat Co. (1962) 210 Cal.App.2d 825, 838 to 840). In that same case, the court upheld a finding that the entity was separate, and it pointed to the company’s separate bank accounts and its payment of its bills on its own checks (id. at pp. 835, 841). My page on piercing the corporate veil in California covers the doctrine in full.

The account also makes the rest of compliance possible. An LLC has to keep its books and records on internal affairs for the current and past four fiscal years (§ 17701.13(d)(7)). A single account with a clean history is most of that record.

What documents do I need to open an LLC bank account in California?

Bring the items below to the first meeting, plus anything the bank’s own policy adds, and the account usually opens the same day.

Document	Why the bank wants it	Where it comes from
Filed articles of organization (Form LLC-1)	Proves the LLC exists	Secretary of State, bizfile Online
EIN confirmation letter	Tax ID for the account	IRS, free online
Operating agreement, or a resolution of the members or managers	Shows who can open the account and sign	Your own records
Photo ID and personal information for each 25% owner and one control person	Federal customer due diligence rule	Each owner
Fictitious business name statement (only if the account uses a name other than the LLC’s)	Shows the LLC’s right to use that name	County clerk

Some banks also ask for a certificate of status from the Secretary of State, or the current Statement of Information. If the LLC is suspended, fix that first. My page on suspended LLCs and corporations explains why a suspended company can’t legally do business.

Why does the bank ask about the LLC’s owners?

Federal law requires it. Banks must identify and verify the beneficial owners of a “legal entity customer,” which includes an LLC (31 C.F.R. § 1010.230).

A beneficial owner means each individual who owns 25 percent or more of the equity interests, plus a single individual with significant responsibility to control, manage, or direct the company, such as a manager or chief executive (31 C.F.R. § 1010.230(d)). The bank collects each person’s name, date of birth, address, and Social Security number, according to FinCEN’s February 2026 order. An LLC with four equal members has four 25% owners, and the bank will want all four plus the control person, who may be one of them.

If your living trust holds the LLC interest, which is how I set up most clients, the bank treats the trustee as the beneficial owner for that interest (31 C.F.R. § 1010.230(d)(3)). Bring the trust’s certification along with your ID. My trust funding page explains why the interest belongs in the trust.

What changed in 2026

Two recent federal changes affect this.

The bank rule got lighter for later accounts. On February 13, 2026, FinCEN issued an order excusing banks from re-identifying a business customer’s beneficial owners each time it opens a new account. Banks now have to do it when the customer first opens an account, when they learn facts calling the earlier information into question, and as their own risk-based procedures require, according to FinCEN. Your second LLC account at the same bank should need less paperwork than the first. The relief is optional, and a bank can still ask every time.

The federal BOI report went away for U.S. companies. FinCEN’s beneficial ownership page says U.S. companies are exempt from BOI reporting under its final rule. That’s a separate federal filing, not the bank’s own form. The bank’s customer due diligence questions still apply. My BOI report page tracks the reporting rule.

Do I need an EIN to open an LLC bank account?

Almost always, and it’s free. The IRS issues an EIN online, immediately if the application is approved, at no charge. You can apply for one EIN per responsible party per day, according to the IRS.

A multi-member LLC needs its own EIN. A single-member LLC that’s disregarded for tax, with no employees and no excise tax liability, doesn’t need an EIN for federal tax purposes. The IRS says that LLC can still get an EIN if it needs one to open a bank account, and most banks will ask for one. Once you have employees, the LLC must use its own name and EIN for employment tax, according to the IRS.

Be careful with sites that charge to “obtain your EIN.” The IRS says its online tool gets an EIN directly from the IRS for free.

Who can sign on the LLC’s bank account?

It depends on how the LLC is managed, and the bank will ask. That’s where the operating agreement earns its keep.

In a member-managed LLC, every member is an agent of the LLC for its business, and a member’s act in the usual course of business binds the LLC unless the member lacks authority and the other party knows it (§ 17703.01(a)). In a manager-managed LLC, a member acting only as a member isn’t an agent and can’t sign for the LLC, and each manager is (§ 17703.01(b)).

A restriction in your operating agreement, such as “two signatures on checks over $10,000,” is effective only against people who have actual knowledge of it (§ 17703.01(c)). If you want the bank to enforce it, put it in the bank’s signature card or resolution, not only in the agreement. My page on member-managed vs. manager-managed LLCs covers the choice itself.

A sample banking resolution

Many banks have their own form. If yours doesn’t, a short written consent of the members covers it:

• The LLC’s name, Secretary of State file number, and EIN.
• The bank and the type of account being opened.
• The people authorized to open, sign on, and close the account, by name and title.
• Any dual-signature threshold or limits on online transfers.
• Who may borrow in the LLC’s name, if anyone. That’s a separate power from signing checks.
• The members’ signatures and the date.

Can the account be in my DBA name?

Yes, if the LLC has filed a fictitious business name statement for it. For an LLC, a fictitious business name is any name other than the one in its articles (Bus. & Prof. Code § 17900(b)(5)). Anyone regularly doing business under one must file a statement within 40 days of starting (Bus. & Prof. Code § 17910(a)).

Skipping it has a cost beyond the bank. A business operating under a fictitious name without filing can’t sue on a contract made in that name until it files and publishes the statement (Bus. & Prof. Code § 17918). My DBA guide walks through the county filing.

How should I run the LLC’s bank account?

Run every business dollar through it and no personal dollars. The details below are the ones that come up when a creditor or a buyer’s lawyer looks at the account later.

1. Fund it on day one. Deposit the members’ initial contributions and record them in the member list the LLC must keep (§ 17701.13(d)(1)).
2. Pay yourself by transfer, and label it. A distribution or a guaranteed payment goes from the LLC account to your personal account with a memo. Paying your mortgage straight from the LLC account is the pattern that looks like commingling.
3. Put loans in writing. If you lend the LLC money, sign a note. If the LLC lends you money, sign one too and repay it.
4. Sign as the company. On checks and contracts, sign “Pacific Coast Tile LLC, by Maria Lopez, Manager,” not your name alone.
5. Keep the card in the company’s name. A personal card used for business purchases turns into a reconstruction project for your CPA.
6. Keep the account open and in good standing. If the LLC stops filing with the state, the account becomes a problem for the bank as well.

A worked example

Two sisters in Oxnard form a catering LLC with $15,000 each. They open an account the day the EIN arrives and deposit $30,000. One sister buys a $4,000 oven with her personal card in a rush. The fix is simple: the LLC reimburses her from its account with an invoice attached, and the bookkeeper records it. That’s a documented business expense. Letting the oven sit on her personal card, and having the LLC “pay her back someday,” is how the line between the sisters and the company starts to blur.

Is my LLC’s bank account FDIC insured separately from my personal accounts?

Generally yes. The FDIC says deposits owned by an LLC are insured in the business ownership category, separately from the personal deposits of the LLC’s members. All of the LLC’s accounts at one bank are added together and insured up to $250,000, according to the FDIC, so an operating account and a reserve account at the same bank share one limit.

There’s a condition. The LLC must be engaged in an “independent activity,” which the FDIC describes as operating primarily for some purpose other than increasing deposit insurance coverage. If an entity isn’t, its deposits are treated as owned by the people behind it (12 C.F.R. § 330.11(d)). An LLC that runs a real business through its account meets that test without trying.

What about personal guarantees?

Expect them for credit, not for a checking account. The LLC statute keeps a member’s liability for a guarantee the member signs (§ 17703.04(c)). A business line of credit or card for a new LLC usually comes with a personal guarantee, and the separate bank account doesn’t change that. My page on personal guarantees on commercial leases explains how to narrow one.

What happens to the account when an owner dies?

The account belongs to the LLC, so it doesn’t pass through anyone’s estate. The question is who has authority to sign after the death. If the only signer dies and the operating agreement doesn’t name a successor manager, the account can freeze while the family sorts out who controls the LLC. My page on what happens to an LLC when the owner dies covers the fix, and business succession planning covers the larger plan.

Frequently asked questions

What do I need to open a business bank account for an LLC in California?

The filed articles of organization, the LLC’s EIN, the operating agreement or a banking resolution, and ID for each 25% owner and one control person. Banks must collect the owner information under the federal customer due diligence rule (31 C.F.R. § 1010.230). Some banks also ask for a certificate of status.

Can I open an LLC bank account with my Social Security number instead of an EIN?

Sometimes, for a single-member LLC with no employees. The IRS says that LLC doesn’t need an EIN for federal income tax purposes but can get one to open a bank account. Most banks prefer the EIN, and it keeps your SSN off the LLC’s paperwork.

Is it illegal to use my personal account for my LLC?

It’s a liability problem more than a legal violation. Commingling funds is one of the factors California courts weigh in deciding whether to disregard an LLC and hold the owner personally liable (Associated Vendors, Inc. v. Oakland Meat Co. (1962) 210 Cal.App.2d 825, 838 to 840). It also makes your books harder for your CPA.

Do I need an operating agreement to open an LLC bank account?

Many banks ask for one, and a banking resolution usually satisfies the rest. California law makes every member of a member-managed LLC its agent (§ 17703.01(a)), so the bank wants to see who you’ve limited. My operating agreement guide covers what to include.

Can I open an LLC bank account online?

Many banks allow it. The documents are the same, and the owners’ identity information is still required. Online-only providers may ask for extra verification of each owner.

Can two LLCs share one bank account?

Don’t do it. Each LLC is a separate entity, and running two companies through one account is the kind of mixing the alter ego factors describe. If you have a holding company structure, each entity gets its own account, and money between them moves by documented transfer.
