Startup Bank Account Checklist for Branch Day

The branch checks the entity before it checks the idea

You just formed the company, and the first business bank account is the next concrete step. The branch needs the folder to prove the entity, the tax ID, the owners, the signers, and the address.

Keep originals in one folder and copies in another, so you can hand over the original and still have the backup. The folder should be complete enough to verify without a second trip. Keep it flat, not loose in a bag.

Bring the folder in the order the branch will ask

Print the items in that order. A DBA, a partnership, or more than one owner makes the folder thicker, but the shape stays the same.

• State formation document, such as Articles of Organization, the state filing that creates an LLC and that banks use to confirm legal formation and ownership structure.
• EIN letter or EIN, especially for corporations, partnerships, and multi-member LLCs, with an SSN only for a sole proprietor if the bank accepts it.
• One original primary identification document and one original secondary identification document for each owner.
• All notarized signer forms from absent owners or key executives, returned before the account opens.
• A physical business address, not a registered agent, virtual address, PO box, or commercial mailbox.
• A DBA or trade-name certificate linking the alternate name to the existing entity without creating a separate entity or changing ownership or liability.
• A signed partnership agreement when applicable.

Before you leave for the branch, test each item: can the branch see it, verify it, and file it? When the answer is no, fix it first.

The gaps that stop the account

The formation document is the first thing the branch checks. It anchors the account name, ownership, and management structure. Mismatched details can delay the account.

The tax ID separates the business from the owner. It also makes payroll, tax filings, and vendor records easier to sort. An ID letter that does not match the entity name needs fixing before the appointment.

Owner IDs and signer forms answer the same question: who is allowed to bind the company? The branch needs to see who actually controls the entity, not just who appears on the formation page. An incomplete signer list can end the visit without an account.

The address is where the branch can reach the business and verify that it is operating. A missing or weak address can turn a routine visit into a second trip.

The DBA keeps the marketing name, account name, invoices, and legal records aligned. The partnership agreement, when applicable, shows how the owners split control, who can sign, and how decisions are made. A signed, current agreement can prevent a long pause while the branch asks for proof of authority.

Fix the weak spots the night before

Start with the people. If the entity names two owners and only one is coming, get the missing person's notarized forms ready. When the missing person cannot appear, ask the branch what substitute authority it will accept before you go.

Check the location next. A home office, coworking suite, or service address needs a quick call before the appointment. If it will not qualify, bring a different physical location that the business can use.

Match the names. The legal name on the formation document, the tax ID letter, the identification cards, and the signer forms should line up. A trade name in use needs the certificate that ties the marketing name to the legal name.

Check the signer list against the bank's form. Use the titles the bank will recognize, and bring ownership percentages from the ownership document when the form asks for them. A clean match saves the branch from asking you to leave and return. Lay the folder out the night before a morning appointment.
