How to open a business bank account for an LLC

To open a business bank account for your LLC, you need three documents: your IRS Employer Identification Number (EIN) confirmation letter, your state-approved Articles of Organization, and (usually) your LLC's Operating Agreement, plus a government ID for anyone who'll have signing authority. Most banks can process an application in under 15 minutes once you have those ready. The harder part isn't the paperwork. It's understanding what business banking actually involves so you pick the right account instead of the first one you find.

This article is a step-by-step guide to the documents, account types, and decisions that protect the liability shield you formed your LLC to get.

Do you need a separate business bank account for your LLC?

Yes. For an LLC, a separate bank account isn't a nice-to-have: it's what protects the liability shield you formed the LLC to get in the first place.

When you form an LLC, you're creating a legal wall between your personal assets and your business's debts and liabilities. That wall only holds up if you actually treat the business as a separate entity, starting with how you handle a business bank account versus a personal one. If you deposit client payments into your personal checking account, pay business expenses off a personal credit card, or otherwise mix business and personal money, a court can invoke a legal doctrine called "piercing the corporate veil." That doctrine disregards your LLC's liability protection entirely and holds you personally responsible for business debts.

Beyond the legal risk, a mixed account makes LLC tax rates unnecessarily painful to sort out. Every personal coffee run becomes a transaction you have to manually exclude at tax time.

There's one common point of confusion worth clearing up: This rule is different for sole proprietors, who aren't legally required to separate business and personal funds since there's no liability shield to protect in the first place (though it's still good practice, and choosing a business credit card as a sole proprietorship follows similar logic).

If you're not sure which structure you're operating under, LLC vs. corporation breaks down the legal and tax differences, and keeping your finances separate from the start makes several LLC tax benefits easier to claim later.

What you need before you apply

Before you start an application, gather these documents:

Bring your EIN documentation even if you think you remember the number. Banks require the official confirmation letter, not just the number itself. If you haven't applied yet, getting an EIN doesn’t cost anything, and some banks will also ask for a certificate of good standing confirming your LLC is still active with the state.

Can you open a business bank account with just an EIN?

In most cases, an EIN alone is not sufficient because banks typically require ownership and identity verification documentation. An EIN identifies your business for tax purposes, but it doesn't establish who owns or controls it. Federal law requires banks to verify ownership before opening an account, so you'll still need your formation documents and a government ID alongside the EIN. The same limitation shows up with business credit cards with EIN only, since lenders run into the same verification requirement.

The one exception: Single-member LLCs and sole proprietors can open a business account using a Social Security number instead of an EIN. Most banks recommend getting an EIN anyway, since it adds a layer of separation between your business and personal identity.

Step-by-step: How to open the account

1. Gather your documents. EIN confirmation letter, Articles of Organization, Operating Agreement, and ID for every signer.
2. Decide who needs signing authority. Multi-member LLCs should confirm this in the Operating Agreement before applying. Banks will ask.
3. Compare account options. Look at fees, minimum balance requirements, transaction limits, and how the bank handles Automated Clearing House (ACH) transfers, wires, and card payments (more on what to prioritize below).
4. Apply online or in person. Most banks and business-banking platforms now offer online applications that take 10–15 minutes.
5. Fund the account. Some banks require an opening deposit. Others don't.
6. Update your records. Add the new account to your bookkeeping software and start routing all business income and expenses through it exclusively. Maintaining separate business finances may support future credit applications and business financial reporting.

Choosing the right account type for your LLC

Your LLC needs two things from a bank account: a place to hold operating cash and pay bills, and a way to pay yourself. How you set that up depends on your structure.

Checking vs. savings. A business checking account handles day-to-day transactions: vendor payments, payroll, and incoming client payments. A savings or high-yield account is where you park cash you don't need immediately, so it earns something instead of sitting idle. You might use both: checking for day-to-day operations, plus a separate account for tax reserves or a cash cushion.

Paying yourself from LLC funds. Most LLCs default to sole proprietorship or partnership tax treatment. That means you pay yourself through an "owner's draw" (a transfer from the business account to your personal account, not a paycheck with tax withholding). If you've elected S-corp taxation, you'll need to run payroll instead.

Either way, the transfer should come from your dedicated LLC account, never from a shared or personal one. Mixing the two is exactly the pattern that puts your liability protection at risk.

What to look for in a business bank account for an LLC

Once you've got your documents in order, the decision comes down to a handful of criteria: fees and minimums, payment speed, how much reconciliation the bank automates for you, and deposit protection. A rundown of the best business checking accounts on the market shows how much these criteria vary by provider.

Ramp Checking Account* is built around those specific criteria, and it's available to the more than 70,000 businesses that run on Ramp. There are no fees or minimums: free to open, free to maintain, no balance requirement. Ramp offers free instant payments via Real-Time Payments (RTP), plus unlimited free same-day ACH transfers and wires¹ for bill payments—pick the method, skip the fee.

On the operations side, Ramp automates a large share of bank transfers for customers using its Cash Manager tools and keeps Ramp payments reconciled without manual matching, so less of your LLC's bookkeeping depends on manual entry. Eligible deposits may receive aggregate FDIC insurance coverage above standard per-bank limits through IntraFi's ICS network², subject to program requirements and applicable FDIC rules. Worth checking the coverage figure against whatever your LLC typically holds in reserve.

If you're weighing business credit cards for your LLC at the same time, it's worth choosing a bank account and card that share the same platform. It cuts down on the number of places your LLC's money and transaction data live.

Getting your LLC's bank account open

Opening a business bank account for your LLC takes an afternoon once your paperwork is in order. The part worth spending more time on is picking an account that matches how your LLC actually operates: low fees, fast payments, and enough automation that reconciliation isn't a monthly chore. And if the account you pick stops fitting as your LLC grows, switching business bank accounts later is more straightforward than most owners expect. Ramp Checking Account is built for exactly that combination, with no fees or minimums to get in the way.
