One of the first things you should do after forming your LLC is open a dedicated business bank account. It is not just good practice. It is essential for maintaining the legal separation between you and your business that makes your liability protection real. Using your personal account for LLC transactions is one of the fastest ways to lose the protection your LLC was designed to give you.
Quick Answer
To open a business bank account for your LLC you typically need your EIN (Employer Identification Number), a copy of your Articles of Organization, your LLC operating agreement, and a government-issued photo ID. Some banks also require a business license or a minimum opening deposit. The process takes 15 to 30 minutes in person or a few days online.

Why Your LLC Needs a Separate Business Bank Account
Forming an LLC creates a legal wall between you and your business. That wall only holds if you treat the LLC as a genuinely separate entity. The moment you start mixing personal and business money, courts call this "commingling of funds" and it is one of the top reasons judges pierce the corporate veil and hold LLC members personally liable for business debts.
Beyond liability protection, a dedicated LLC bank account serves several practical purposes.
- Clean bookkeeping. Every business transaction flows through one account, making tax time dramatically simpler and reducing the risk of missed deductions.
- Professional credibility. Clients and vendors expect to pay a business entity, not an individual. Receiving payments in your LLC name builds trust.
- Accurate profit tracking. You cannot know what your LLC actually earns if business money is mixed with personal money. A separate account gives you a clear picture of business performance.
- Tax compliance. The IRS expects LLCs to have clean financial records. Mixed accounts raise red flags and complicate any audit. See our guide on how an LLC is taxed for the full picture of what the IRS expects from LLC owners.
- Smoother loan applications. Lenders require business bank statements when evaluating LLC loan applications. A personal account does not qualify.
What You Need to Open an LLC Business Bank Account
Most banks require the same core set of documents. Gather these before you go to the bank or start an online application.
1. EIN (Employer Identification Number)
Your EIN is your LLC's federal tax identification number, issued by the IRS. Every bank requires it to open a business account. You cannot use your personal Social Security Number for an LLC account. If you formed your LLC through Brendat's Standard or Premium plan, your EIN is already filed. If not, apply at IRS.gov for free or add it through Brendat's service.
2. Articles of Organization (state-stamped copy)
This is the document your state issued when your LLC was officially formed. Banks use it to verify that your LLC legally exists. You need the state-approved, stamped copy, not just a draft. Brendat provides this document digitally as part of every formation plan.
3. LLC Operating Agreement
Your operating agreement is the internal document that defines who owns the LLC and who has authority to open bank accounts on its behalf. Banks ask for it to confirm that you, as the person opening the account, have the legal authority to do so. Single-member LLCs need this too. Brendat's Standard plan includes a professionally drafted operating agreement.
4. Government-Issued Photo ID
A current driver's license or passport for each person signing on the account. If your LLC has multiple members, all authorized signatories typically need to be present or submit IDs.
5. Business License (if required)
Some banks, especially community banks and credit unions, ask for a local business license. This varies by bank and by your industry. Check with your chosen bank in advance to avoid a wasted trip.
6. Opening Deposit
Many traditional banks require a minimum opening deposit, typically $25 to $100 for a basic business checking account. Some online banks and fintechs require no minimum deposit. Check the bank's current requirements before applying.
Brendat Tip
Get your EIN and operating agreement in place before approaching any bank. These are the two documents most commonly missing when LLC owners try to open accounts, and missing either one will delay the process by days or weeks.
Step-by-Step: How to Open an LLC Business Bank Account
1. Form your LLC and get your EIN first
You cannot open a business bank account without a legally formed LLC and an EIN. If you have not formed your LLC yet, Brendat handles the entire process including EIN filing in the Standard plan. Formation typically takes a few business days to a few weeks depending on your state.
2. Choose your bank type
Decide between a traditional bank, an online bank, or a credit union based on your needs. Each has different fee structures, features, and application processes. More on this in the next section.
3. Gather your documents
Collect your EIN confirmation letter, state-stamped Articles of Organization, operating agreement, and government-issued ID. Call the bank in advance to confirm their exact document requirements, as these vary.
4. Apply in person or online
Traditional banks usually require an in-person visit to open a business account, at least for the first account. Online banks handle everything digitally: you upload documents and complete identity verification through their app or website. Online applications typically take 1 to 3 business days for approval.
5. Fund the account and set up access
Make your opening deposit, set up online banking access, and order business debit cards for authorized members. If you use accounting software like QuickBooks or Wave, connect your new account immediately so transactions sync automatically from day one.
6. Update all payment and invoicing details
Notify clients of your new business account details, update any payment processors (Stripe, PayPal, Square), and redirect all LLC income and expenses to flow through the new account. From this point forward, no personal account transactions for LLC business.
Best Types of Banks for LLC Accounts
Traditional banks (Chase, Bank of America, Wells Fargo)
Pros: physical branches for in-person needs, full suite of business services including loans and merchant accounts, established reputation and FDIC insurance. Cons: monthly maintenance fees unless you maintain a minimum balance, slower account opening process, sometimes stricter documentation requirements.
Online banks and fintechs (Mercury, Relay, Bluevine, Novo)
Pros: no monthly fees on most accounts, fast online application (often approved in 1 to 2 days), modern interfaces that integrate with accounting software, no minimum balance requirements. Cons: no physical branches, limited cash deposit options, some have caps on transaction volume. Popular with early-stage LLCs and remote businesses.
Credit unions
Pros: often lower fees than traditional banks, more personalized service, better interest rates on savings. Cons: membership requirements, fewer branch locations, less robust business banking features than major banks.
Recommendation for most new LLCs
Start with an online bank like Mercury or Relay for the first year. Zero fees, fast setup, and clean integrations with accounting software. Once your LLC has consistent revenue and you need a business loan or merchant services, add a relationship with a traditional bank. You can have accounts at multiple institutions.
Can You Use a Personal Bank Account for Your LLC?
Technically, nothing stops you from depositing LLC revenue into your personal account. But doing so carries serious consequences that most new LLC owners do not fully appreciate.
Using a personal account for LLC transactions is the primary example of commingling funds. Courts treat this as evidence that your LLC is not a genuine separate entity. If your LLC is ever sued or cannot pay its debts, a judge can use commingled finances as the reason to pierce the corporate veil and hold you personally liable for business obligations.
The liability protection that makes an LLC valuable depends entirely on maintaining genuine separation. A personal account for LLC business does the opposite.
The risk is real
Your LLC's liability protection is not automatic just because you filed Articles of Organization. Courts look at how you actually operated the business. Commingled finances are one of the top reasons LLC members lose their personal liability protection when challenged in court.
Business Checking vs Business Savings for LLCs
Most LLCs start with a business checking account and add a savings account later. Here is when each makes sense.
A business checking account handles all day-to-day transactions: receiving payments, paying suppliers, payroll, and operating expenses. This is the primary account your LLC needs from day one.
A business savings account is useful once your LLC has consistent cash flow. Common uses include setting aside quarterly tax payments (as an LLC owner you pay estimated taxes quarterly), building a cash reserve for slow months, and separating funds earmarked for equipment or expansion.
A practical approach many LLC owners use: keep one to three months of operating expenses in a business savings account at all times. Transfer your quarterly estimated tax amount to savings when you calculate it, so it is never accidentally spent before the payment deadline.
Frequently Asked Questions
Do I need a business bank account for my LLC?
Yes. While no law forces you to open one, operating without a separate business account puts your personal liability protection at serious risk. Using personal accounts for LLC transactions is treated as commingling funds, which courts use as evidence that the LLC is not a genuine separate entity. It can also result in your LLC's liability shield being removed if you are ever sued.
What documents do I need to open an LLC bank account?
Most banks require your EIN, a state-stamped copy of your Articles of Organization, your LLC operating agreement, and a government-issued photo ID. Some banks also ask for a business license or a minimum opening deposit. Call your chosen bank in advance to confirm their specific requirements.
Can I open a business bank account without an EIN?
No. Every bank requires an EIN to open a business account for an LLC. You cannot substitute a personal Social Security Number for an LLC account. Apply for your EIN at IRS.gov for free, or Brendat includes EIN filing in the Standard formation plan.
Can a single-member LLC open a business bank account?
Yes. Single-member LLCs open business bank accounts the same way as multi-member LLCs. You need the same documents: EIN, Articles of Organization, operating agreement, and ID. Banks do not require multiple members to open a business account.
How long does it take to open an LLC business bank account?
In person at a traditional bank: typically 30 to 60 minutes if your documents are complete. Online with a fintech bank: the application takes 15 to 20 minutes, and approval usually comes within 1 to 3 business days. Some online banks approve and activate accounts same day.
Can I use one bank account for multiple LLCs?
No. Each LLC is a separate legal entity and must have its own dedicated bank account. Mixing funds between two separate LLCs creates the same commingling problem as mixing LLC and personal funds. Each LLC needs its own account, its own EIN, and its own financial records.
