Using a personal checking account for an LLC is one of the most common early mistakes new business owners make, and it can be a costly one. Mixing personal and business funds — known as "commingling" — can undermine the liability protection an LLC is meant to provide in the first place, since a court can decide the business was never really operated as a separate entity. A dedicated business account is not just a convenience; it's part of what keeps the LLC's legal protection intact.
What to actually compare between accounts
- Monthly maintenance fees and how to waive them — most business accounts charge $10-25/month unless a minimum balance or transaction volume is met; check whether that threshold is realistic for your actual cash flow.
- Free transaction limits — many accounts include a fixed number of free monthly transactions (deposits, withdrawals, transfers) and charge per transaction beyond that, which matters a lot for high-volume businesses like retail or e-commerce.
- Cash deposit limits — relevant mainly for cash-heavy businesses; online-first business banks often cap free cash deposits sharply or don't support them at all.
- Integration with accounting software — direct sync with tools like QuickBooks or Xero saves significant bookkeeping time compared to manual CSV exports.
- APY on any balance held — often negligible at traditional banks, but some online-first business accounts pay a meaningful rate on idle cash.
Traditional bank vs. online-first business bank
Traditional banks offer in-person support and easier cash handling, which matters for businesses that regularly deal with physical cash or need a same-day relationship with a banker for a loan application. Online-first business banking platforms typically offer lower or no monthly fees, faster account opening, and better software integrations, but rely entirely on phone or chat support and can be less practical for cash-heavy operations. Neither is a wrong choice; it depends on how the business actually operates day to day.
What you'll typically need to open the account
- EIN (Employer Identification Number) from the IRS, or in some cases the owner's SSN for a single-member LLC without employees.
- Articles of Organization (or Certificate of Formation, depending on the state).
- The LLC's Operating Agreement, even if informal.
- A business license, if one applies to your industry and location.
- Government-issued ID for each authorized signer on the account.
A step most new LLC owners skip
Beyond opening the account, actually routing all business income and expenses exclusively through it — including paying yourself a defined owner's draw rather than pulling cash directly from client payments — is what preserves the separation a court would look for if the LLC's liability shield is ever challenged. The account only protects you if it's genuinely used as the boundary between personal and business finances, not just opened and left mostly unused.
