How to Open an LLC Business Bank Account

Documents Banks Typically Require

Most banks ask for a consistent set of documents to open an LLC business account, though exact requirements vary by bank:

• Approved Articles of Organization, the state-stamped or certified document confirming your LLC legally exists.
• EIN confirmation letter, the notice the IRS issued when you applied for your Employer Identification Number.
• Operating agreement, which banks use to confirm who is authorized to act on the LLC's behalf, even in states where the law doesn't require one to exist.
• Personal identification, such as a driver's license or passport, for anyone who will be an authorized signer on the account.
• A business license, if your city or county requires one for your type of business, though not every bank asks for this upfront.

Call ahead or check the bank's business banking page before your appointment, since some banks require an in-person visit to open a business account while others allow it online.

Why You Need an EIN, Even if the IRS Doesn't Require One

A single-member LLC that's a disregarded entity with no employees and no excise tax liability can file federal taxes under the owner's Social Security number, according to the IRS. Most banks, however, require an EIN to open a business account regardless, since they generally won't open an account under a personal SSN tied to a business name. Getting an EIN is free and usually immediate through the IRS's online application, so there's little reason to skip it even if your tax situation technically allows it.

Banks Verify Your LLC's Beneficial Owners

Separate from any state or IRS filing, FinCEN's Customer Due Diligence (CDD) rule requires banks to identify and verify the beneficial owners of a legal entity customer, including an LLC, when it first opens an account at that institution. As of a February 2026 FinCEN exceptive relief order, this verification generally happens once per banking relationship rather than at every single new account, so an LLC that already has an account at a bank typically doesn't need to re-verify beneficial ownership information each time it opens an additional account there. Expect the bank to ask for the name, date of birth, address, and identification number of each individual who owns 25% or more of the LLC, along with one individual with significant control over it.

This Is Different From BOI Reporting to FinCEN

The bank's beneficial ownership questions are separate from the Beneficial Ownership Information (BOI) report that the Corporate Transparency Act originally required many LLCs to file directly with FinCEN. Under a 2026 FinCEN final rule, domestic companies, including LLCs formed under U.S. state law, are exempt from that BOI reporting requirement; only certain foreign companies registered to do business in the U.S. remain subject to it. Your bank's own beneficial ownership verification at account opening still applies regardless of this change, since it's a separate requirement aimed at the bank, not at your LLC's own filing obligations.

Why a Separate Business Account Matters

Opening a dedicated account for your LLC, rather than running business income and expenses through a personal account, supports the liability protection an LLC is meant to provide. Commingling business and personal funds is one of the clearest ways a court can find that an LLC isn't being treated as a genuinely separate entity, which can undermine the protection against personal liability that forming the LLC was meant to secure.

Choosing a Bank

Compare monthly fees, minimum balance requirements, transaction limits, and whether the bank offers the specific services your business needs, such as merchant payment processing or integration with accounting software. A local or regional bank may offer more personalized service for a small LLC, while a larger national bank may offer more extensive online and mobile tools.

Keep the Account Strictly for Business Use

Once opened, run all business income and expenses through the LLC's account, and avoid using it for personal purchases or transferring funds back and forth informally with a personal account. Consistent separation matters more over time than how the account was opened in the first place.

Update the Bank When Ownership or Management Changes

If a member or manager changes, or if your operating agreement is amended to reflect a different authorized signer, notify your bank and update its records. A bank account that still lists a former manager as an authorized signer can create confusion or delay if that person is no longer with the business.

Online-Only Banks May Have Different Requirements

Some online-only or fintech banking platforms serve LLCs with a simplified application process, but they're still subject to the same federal beneficial ownership verification rules as a traditional bank. Confirm an online bank is FDIC-insured, through its own charter or a partner bank, before relying on it for your LLC's funds.

A Multi-Member LLC May Need a Banking Resolution

If your LLC has multiple members, especially in a manager-managed structure, the bank may ask for a banking resolution, a document the members sign authorizing specific individuals to open and manage accounts on the LLC's behalf, in addition to your operating agreement.

This Isn't Legal or Tax Advice

Beneficial ownership rules, BOI reporting status, and bank-specific documentation requirements can change; confirm current requirements directly with your bank and, if your ownership structure is complex, a business attorney before opening an account.
