Small-business deposit decisions are not simply personal-finance decisions with a different tax ID. The entity structure, the number of authorized signers, the transaction volume, and the cash reserve size all affect which institution and which account type makes financial sense.

Decision 1: Entity Type and FDIC Coverage

FDIC coverage applies to deposits in the business entity's name separately from the owner's personal accounts. A sole proprietor's business accounts and personal accounts at the same bank are aggregated — they share the $250,000 limit. An LLC or corporation has its own separate $250,000 coverage at the same institution. This distinction matters if you hold significant cash in both personal and business accounts at the same bank.

Decision 2: Checking vs Savings for Operating Cash

Business checking accounts typically pay no interest or very low interest. Business savings accounts pay competitive rates but have transaction limits. The practical architecture: keep one month of operating expenses in the business checking account (for ACH debits, payroll, vendor payments), and hold reserves in a business savings account or money market account at a bank paying 4–5%.

Decision 3: Choosing the Right Bank Type

Big-four banks offer the best infrastructure (wire transfers, ACH, business credit cards, SBA loan relationships) but the worst deposit rates. Online-only banks (Relay, Bluevine, Mercury) offer competitive rates but thinner infrastructure. Regional banks often provide the best compromise: relationship banking, SBA loan access, and deposit rates that are not as low as the big-four.

Decision 4: Fee Structure at Scale

Business account fees are driven by transaction count, wire volume, and number of ACH debits. A business with 10 transactions per month has different needs than one with 500. At high transaction volumes, big-four business checking accounts can become cost-effective despite higher fees because per-transaction fees are waived at higher tiers. At low volumes, fee-free online business banks are clearly superior.

Decision 5: Documentation Required

Every business bank account requires: EIN (or SSN for sole proprietors), Articles of Incorporation or Certificate of Formation (LLC/corp), Operating Agreement or bylaws, government-issued ID for all beneficial owners over 25% equity. Since 2018, banks are required under FinCEN's beneficial ownership rule to collect this information. Having it ready before the appointment saves time.

Frequently Asked Questions

Can a sole proprietor open a business savings account?

Yes. A sole proprietor can open a business account using their SSN as the tax ID (if no EIN is obtained). Some banks require a fictitious business name (DBA) registration if the business name differs from the owner's legal name. FDIC coverage note: sole proprietor business and personal accounts at the same bank are aggregated under the $250,000 limit.
