How to Open a U.S. Business Bank Account
A dedicated business bank account isn’t just tidy — it’s part of what keeps your LLC’s liability shield intact. Running every dollar through a separate business account is the single clearest way to show your company is a real, distinct entity, and it makes bookkeeping and taxes dramatically easier. This guide walks through what you’ll need to open one, the step-by-step process, and the realistic options for non-US founders who can’t walk into a U.S. branch.
Why a separate account matters
The biggest reason is legal: if you pay personal bills from the business account or vice versa (“commingling”), a court can decide the LLC isn’t really separate and pierce your liability shield — wiping out the main benefit of forming an LLC.
The practical reasons stack up too: clean books, painless tax filing, easier access to business credit, and a more professional impression when clients pay “Acme LLC” instead of your personal name.
What you’ll typically need
Most banks ask for your approved Articles of Organization (formation documents), your EIN confirmation letter from the IRS, an operating agreement, a business address, and a government-issued ID for each owner.
Have these ready before you apply — a missing operating agreement or an EIN that doesn’t match your legal name is the most common reason applications stall.
The process, step by step
First, form the LLC and get it approved. Second, obtain your EIN from the IRS. Third, draft an operating agreement. Fourth, choose between a traditional bank (some require an in-person visit) and a digital business banking platform (apply entirely online).
Then apply with your documents in hand, fund the account, and immediately route all business income and expenses through it. From day one, never pay a personal expense from this account.
Options for non-US founders
You generally don’t need to fly to the U.S. Several fintech and digital business-banking platforms are built for non-US owners of U.S. LLCs and let you apply online, though eligibility and supported countries vary — some restrict certain regions.
Approval odds improve with a valid EIN, a U.S. business address or virtual mailbox, and clear documentation of what your business does. If one platform declines you, another may approve you, so it’s worth having a backup. The Non-US LLC Assistant maps current options to your country.
