Why a Separate LLC Bank Account Matters
A separate business bank account is the most basic step in maintaining the corporate veil of an LLC. Mixing personal and business money in a single account, also called commingling, can lead a court to pierce the corporate veil, which means the owner becomes personally liable for the LLC debts. A dedicated business account also makes tax preparation much easier, since the LLCs income and expenses are already segregated. Most banks offer a free or low cost business checking account that comes with a debit card, online bill pay, mobile check deposit, and free ACH transfers, so the cost of separation is low.
Documents Required to Open an Account
Most banks require four key documents. The first is the LLC operating agreement or the articles of organization, which proves the LLC exists and lists the owners. The second is the EIN confirmation letter from the IRS, also called the CP 575 or the EIN assigner letter, which is the LLCs federal tax ID. The third is the owners government issued ID, typically a drivers license or a passport. The fourth is the LLCs legal name and physical address, which must match the state filing. Some banks also require a DBA filing, a business license, or a sales tax permit, depending on the state and the type of business.

US Bank, PNC, and Citizens all have competitive business checking accounts, but they are not as widely available as Chase, Bank of America, and Wells Fargo.
How to Open an Account
Most online banks allow fully online business account opening in 10 to 20 minutes. The application collects the LLC legal name, the EIN, the owners personal information, and a government issued ID. The bank verifies the identity through a database check, and the account is typically open within 1 to 3 business days. Traditional banks also offer online applications, but they often require an in person visit to a branch to fund the account and complete identity verification. Bring all four documents listed above, plus a voided check or a deposit slip from the personal account that will fund the opening balance.
Fees to Watch For
Common business banking fees include the monthly maintenance fee, the transaction fee, the cash deposit fee, the wire transfer fee, the overdraft fee, the returned deposit fee, and the foreign transaction fee. The monthly maintenance fee is the biggest and is usually 10 to 30 dollars at traditional banks and 0 dollars at online banks. The transaction fee is 0.20 to 0.50 dollars per transaction above a monthly limit, usually 100 to 500 free transactions. The cash deposit fee is 0.10 to 0.30 dollars per dollar deposited, and brick and mortar banks often charge a flat fee for the first 5,000 to 10,000 dollars in cash deposits. Read the fee schedule before opening the account, and ask the banker to walk through the top 3 most common fees.
How Many Sub Accounts Do You Need
Most online banks allow free sub accounts, which are a great way to budget and to keep track of tax owed. A typical LLC might use 3 to 5 sub accounts: one for operating expenses, one for tax owed, one for owner pay, one for a reserve, and one for a specific project or savings goal. Relay, Mercury, and Novo all offer free sub accounts. Some banks, such as Bluevine, also offer a high yield savings sub account that pays 4.00 percent APY on balances up to 3 million dollars. Setting up the sub accounts takes 10 minutes and saves hours of accounting work at tax time.
Common Mistakes to Avoid
The most common mistake is using a personal account for business expenses, which can lead to a pierced corporate veil and personal liability for the LLC debts. A second mistake is not funding the account with enough capital, which can lead to overdrafts and damaged banking relationships. A third mistake is signing up for a fee heavy account when a free online account would work, which wastes 100 to 360 dollars per year. A fourth mistake is mixing personal and business credit cards, which makes the bookkeeping harder. A fifth mistake is forgetting to reconcile the account monthly, which can let errors and fraud go unnoticed. Set up a monthly reconciliation calendar reminder and review the statement every month.
