What you need before you walk in
A business bank account requires proof that your business exists as a legal entity separate from you personally. The bank will ask for documentation that matches your business structure — sole proprietorship, LLC, corporation, or partnership — and they will verify it against public records.
For a sole proprietorship, you typically need a government-issued ID and your Social Security number. If you operate under a business name different from your legal name, bring a DBA (Doing Business As) certificate from your county clerk's office or a copy of the registration you filed with your state.
For an LLC or corporation, bring your Articles of Organization or Articles of Incorporation — the document you filed with your state's Secretary of State office. The bank will also ask for an EIN (Employer Identification Number) from the IRS, which you can obtain for free online at irs.gov before you visit the bank. If you have not yet received your EIN letter, bring the confirmation email or the IRS Form SS-4 showing your process was accepted.
Bring a government-issued photo ID for the person opening the account. Some banks also ask for a second form of ID or proof of address, such as a utility bill or lease dated within the last 60 days.
Key Takeaways
- You must bring proof of your business structure — a DBA certificate for sole proprietorships, or Articles of Organization or Incorporation for LLCs and corporations.
- An EIN from the IRS is required for most business structures except sole proprietorships, though sole proprietors can obtain one if they have employees or choose to use one.
- Banks verify your business documents against public records, so make sure your state filings are complete and current before you explore.
- The account holder must bring a government-issued photo ID, and some banks require a second form of identification or proof of address.
- Opening typically takes 15 to 30 minutes in person, though account set up and card arrival may take several business days.
Where to open the account
You can open a business account at any bank, credit union, or online-only financial institution. The choice depends on whether you want in-person service, what fees the institution charges, and what features matter to your business.
Traditional banks with physical branches offer in-person support and often have relationships with business lending teams if you plan to borrow later. Credit unions typically charge lower fees and may have more flexible underwriting, but membership requirements vary — some are open to anyone in a geographic area, while others require you to work in a specific industry or belong to an organization.
Online-only banks have no branches but often charge no monthly fees and allow you to open an account entirely by uploading documents. The tradeoff is that you cannot deposit cash in person and customer service is phone or chat only.
What happens during the process
When you arrive at the bank with your documents, a representative will verify your identity and business structure. They will ask basic questions about your business: what you do, how many owners there are, whether you have employees, and what you expect your monthly deposit volume to be. These questions help the bank assess risk and determine which account tier fits your needs.
The bank will run a background check on the account holder and may check your personal credit report, even though this is a business account. Some banks also screen against government lists of sanctioned individuals and entities. This process usually takes a few minutes while you wait.
You will sign signature cards and account agreements. Read the fee schedule carefully — monthly maintenance fees, per-check charges, overdraft fees, and minimum balance requirements vary widely between institutions. Ask whether the bank offers a grace period before fees kick in, which some do for new accounts.
Once you sign, the account is typically open when ready, though the bank may place a temporary hold on deposits while they verify your documents. Debit cards usually arrive within 5 to 10 business days. Checks can take 2 to 3 weeks.
How to handle your business structure if you have not filed yet
If you are operating as a sole proprietor and have not filed a DBA, you can still open a business account using your personal name and Social Security number. The bank will treat it as a sole proprietorship account. You can file a DBA later and update the account name with the bank.
If you plan to form an LLC or corporation but have not yet filed, you must complete that filing before the bank will open a business account under that structure. Filing takes 1 to 2 weeks in most states and costs between $50 and $300 depending on the state. You can file online through your state's Secretary of State website or use a filing service.
Do not open a personal account and use it for business purposes. Banks monitor for this and may freeze the account or close it without warning if they detect business activity on a personal account. The account also will not protect your personal assets from business liability, which is one of the main reasons to separate them.
Documents checklist by business structure
| Business Structure | Documents to Bring | Additional Notes |
|---|---|---|
| Sole Proprietorship | Government-issued photo ID, Social Security number, DBA certificate (if operating under a different name) | No EIN required unless you have employees or choose to obtain one. If you have an EIN, bring it. |
| LLC | Articles of Organization from your state, EIN from the IRS, government-issued photo ID of the member or manager opening the account | If you have not received your EIN letter, bring the IRS confirmation email or Form SS-4 acceptance. |
| Corporation | Articles of Incorporation from your state, EIN from the IRS, government-issued photo ID of the authorized signer | Some banks ask for a corporate resolution authorizing the account opening. Check with your bank first. |
| Partnership | Partnership agreement, EIN from the IRS, government-issued photo ID of the partner opening the account | The bank may require signatures from all partners or a resolution authorizing one partner to open the account. |
What to do if the bank rejects your process
Banks can decline to open a business account if your background check reveals fraud, money laundering convictions, or other financial crimes. They can also decline if your business structure documents do not match their records or if your business is in an industry they do not serve, such as cannabis or high-risk lending.
If you are declined, ask the bank in writing why. They are required to tell you the reason. If it is a documentation issue, you can correct it and reapply. If it is a background issue, you have the right to dispute inaccurate information on your credit report through the credit bureau that provided it.
If you are declined by one bank, try another. Different banks have different underwriting standards. Credit unions and online banks sometimes have more flexible policies than large national banks. Community banks may also be more willing to work with newer businesses.
After the account opens
Once your account is active, set up online banking and review the bill pay options. Most banks offer free bill pay for business accounts, which lets you pay vendors and contractors electronically without writing checks.
If you have employees, you will need to set up payroll. You can do this through your bank's payroll service, a third-party payroll processor like ADP or Gusto, or by working with an accountant. Your bank can direct you to their payroll options.
Keep your business and personal finances separate from day one. Deposit all business income into the business account and pay all business expenses from it. This separation protects you legally and makes tax time much simpler. Your accountant or tax preparer will thank you.
Frequently Asked Questions
Do I need an EIN if I am a sole proprietor?
No. You can use your Social Security number instead. However, obtaining an EIN is free and can be useful if you plan to hire employees later or want to keep your Social Security number private from vendors. You can get an EIN from the IRS website in minutes.
Can I open a business account online without visiting a branch?
Yes, many online banks and some traditional banks allow you to open an account by uploading photos of your documents. The process takes 10 to 20 minutes. However, some banks still require an in-person visit or a video call with a representative to verify your identity.
What if my business documents have not arrived yet?
If you have filed your LLC or corporation but have not received your official documents, bring the confirmation email or receipt showing your filing was accepted. Most banks will accept this temporarily while they verify the filing with your state's Secretary of State office.
How much money do I need to open the account?
Minimum opening deposits vary by bank and account type, ranging from $0 to $500. Many banks have no minimum. Check the bank's website or call ahead to confirm what they require before you visit.
Can I use a business account for personal expenses?
Legally, you can, but it defeats the purpose of separating your finances. Mixing personal and business expenses makes tax filing harder, creates liability issues, and can trigger account closure if the bank detects the pattern. Keep the accounts separate.
