How to Open a Business Bank Account for Your LLC
What documents banks ask for, the best banks for new LLCs in 2026, and why mixing personal and business funds is dangerous.
Opening a dedicated business bank account is the single most important step after forming your LLC. Here's how to do it quickly.
Why a separate account is non-negotiable
Mixing personal and business money ('commingling') can pierce your LLC's liability shield, leaving your personal assets exposed in a lawsuit.
What you'll need
Approved Articles of Organization, EIN confirmation letter from the IRS, operating agreement, and a government-issued photo ID for each owner with 25%+ ownership.
Best banks for new LLCs in 2026
Mercury, Bluevine, Relay, and Novo are online-first with no minimums. Chase and Bank of America are strong if you want physical branches and want to apply for a credit line later.
How to open the account
Most online business banks take 10–15 minutes and approve within 1–2 business days. Traditional banks usually require an in-person visit.
Open the account the same week your LLC is approved. Route every business transaction through it from day one.
