Best Business Checking Accounts for LLCs
April 2026 -- Single-Member and Multi-Member

Legally, you are not required to have a dedicated business account to form an LLC. However, commingling your business and personal funds is one of the primary ways courts allow creditors to 'pierce the corporate veil' and hold you personally liable for business debts -- defeating the entire purpose of forming an LLC. The commingling doctrine is well-established across US jurisdictions: if your business funds are mixed with personal funds, courts may treat the LLC as an extension of you personally. A dedicated business checking account is the most basic and most important step in maintaining your liability protection.

Yes. All major business checking accounts on this list accept single-member LLCs. For single-member LLCs disregarded for tax purposes (taxed as a sole prop on Schedule C), you will need your Articles of Organization and EIN. Some banks will accept your SSN if you have not yet obtained an EIN, but an EIN is strongly recommended even for single-member LLCs -- it keeps your SSN off bank forms, simplifies vendor payments (W-9 forms), and prepares you for when you hire employees or elect S-Corp status.

Standard requirements for an LLC: (1) Articles of Organization stamped by your state -- this is your formation document. (2) EIN letter (Form CP575 or 147C from the IRS). (3) Government-issued photo ID for each account signer. (4) Operating Agreement -- not all banks require this, but Chase, BofA, and multi-member LLCs almost always need it. (5) Beneficial Ownership Certification -- for any owner with 25%+ ownership stake, required under FinCEN rules. (6) Business license or DBA registration if applicable. Fintechs (BlueVine, Mercury, Relay, Novo) have largely digitised this process.

For a new LLC with no established banking history, BlueVine Standard is the best overall option: no monthly fee, no minimum balance, $0 opening deposit, 1.3% APY with activity goals, cash deposits via Green Dot if needed, and $3M FDIC sweep. The application is fully online and most new LLCs are approved within one business day. If you expect to add bookkeepers, partners, or want to implement Profit First, start with Relay instead -- its 20 sub-accounts and native QuickBooks direct feed scale with your business better than BlueVine's single-account structure.

Yes. Multi-member LLCs typically need additional documentation: your Operating Agreement (showing member percentages and management structure), an EIN (mandatory for multi-member LLCs), and beneficial ownership certification for any member with 25%+ ownership. Relay is the best option for multi-member LLCs because of its role-based permissions -- you can give each member access to different sub-accounts and give your CPA view-only access without sharing the primary account credentials. Chase Business Complete is good for multi-member LLCs that need branch access or handle cash.

Consider switching when: (1) Your monthly cash volume exceeds $5,000 and you are at a fintech without good cash support -- move to Chase. (2) Your balance consistently exceeds $250k and you are at Novo or another account without sweep coverage -- move to BlueVine or Mercury. (3) You elect S-Corp status and need sub-accounts for payroll float, tax reserve, and owner distributions -- move to Relay. (4) You hire a bookkeeper and need role-based permissions -- move to Relay or Mercury. (5) You close a funding round and need $3M+ FDIC -- move to Mercury Vault or BlueVine Premier.
