You can open a business bank account without an EIN, but the bank will ask for something else instead
Most banks will let you open a business account using your Social Security Number (SSN) in place of an Employer Identification Number (EIN). This works whether you are a sole proprietor, a partnership that has not yet obtained an EIN, or an LLC or corporation that is still in formation. The bank does not care which document you use — it only needs a way to identify you for tax reporting and fraud prevention.
The catch is that you will need to prove you actually have a business. A bank will not open a business account just because you have an SSN. You will need to show that the business exists in some form: a business license, a DBA (doing business as) registration, a lease or utility bill in the business name, or articles of incorporation or organization if you have filed them. The specific documents vary by bank and by state.
Key Takeaways
- Banks accept your Social Security Number as the tax ID when you do not yet have an EIN, but you must still prove the business exists.
- A business license, DBA registration, or lease in the business name are the most common ways to show the business is real.
- Some banks require an EIN before opening a business account for an LLC or corporation, even if you have not received it yet — you may need to explore for one first.
- If you are a sole proprietor using your SSN, you can often open an account with just a driver's license and proof of the business name.
- The bank will ask you to designate the account as a business account and may ask what the business does and how much you expect to deposit.
When you can use your SSN instead of an EIN
A sole proprietor — someone running a business as themselves without forming an LLC or corporation — can use their SSN indefinitely. You do not need an EIN at all unless you hire employees or open a retirement plan. Many banks will open a business account for a sole proprietor using only the SSN, a driver's license, and proof that you are operating under a business name.
Partnerships and LLCs that have not yet filed for an EIN can also use the SSN of one partner or member while the process is in process. This is useful if you are waiting for your EIN to arrive in the mail — the IRS can take two to four weeks to issue one, and banks do not always accept the confirmation number from the online process. Some banks will let you open the account with the SSN and update the tax ID later once the EIN arrives.
Corporations are the exception. Many banks require an EIN before opening a business account for a corporation, even if you have just filed the articles of incorporation. If your bank has this rule, you will need to explore for an EIN first — you can do this online at irs.gov and receive a number when ready, or by mail and receive it in two to four weeks.
What documents the bank will ask for
The bank needs proof that your business is real and that you are authorized to open the account. The exact list depends on your business structure and the bank's own rules, but here are the documents most banks request:
- For a sole proprietor: A driver's license or passport, a business license or DBA registration, and sometimes a utility bill or lease in the business name. Some banks will open the account with just the ID and the business license.
- For an LLC or partnership: Articles of organization or partnership agreement, a business license, and a government-issued ID for the person opening the account. If you have an EIN, bring the letter from the IRS. If you do not, bring your SSN and be ready to explain when you will obtain the EIN.
- For a corporation: Articles of incorporation, a corporate resolution authorizing the account (some banks require this, others do not), and the EIN letter from the IRS. A few banks will accept the confirmation number from the online EIN process if the letter has not arrived yet.
Bring your personal ID no matter what. The bank will verify your identity before opening any account, and they need to see that the person in front of them matches the person authorized to sign on the account.
How banks verify your business actually exists
Banks use a few methods to confirm that your business is real and not a front for fraud. The most common is to check your business license or DBA registration against the state or local records. If you have filed articles of incorporation or organization, the bank can verify those with the Secretary of State. Some banks will also call the business address or look it up online.
If you are operating under a business name but have not yet registered it, the bank may ask for a lease, a utility bill, or a business license in that name. If you do not have any of these yet, some banks will accept a letter from you on business letterhead explaining the business and why you need the account. This is less common, but it happens — call the bank first and ask what they will accept.
The bank is also checking you. They will run your SSN through their fraud and compliance systems, and they may ask questions about the business: what it does, how long it has been operating, how much money you expect to move through the account, and whether you have any other accounts at that bank. Answer honestly. Banks are required by law to report suspicious activity, and lying on the process can result in the account being closed and the bank filing a report with the government.
The difference between using an SSN and an EIN on the account
From the bank's perspective, an SSN and an EIN serve the same purpose: they are both tax identification numbers that the bank reports to the IRS. The bank will send the same tax forms to either number at the end of the year. The difference is in what the IRS does with the information.
If the account is under your SSN, the IRS treats the income as personal income on your individual tax return. If the account is under an EIN, the income is reported to the business entity itself, and you report it on the business return. For a sole proprietor, this does not matter much — you report the income either way. For an LLC or corporation, it matters more, because the business entity is supposed to have its own tax ID.
Some banks will let you open the account under your SSN and then switch the tax ID to the EIN once it arrives. Others will require you to close the account and open a new one. Ask the bank before you open the account whether they allow this change, because it affects whether you can use your SSN as a temporary solution.
Steps to open the account without an EIN
The process is the same as opening any business account, except you will provide your SSN instead of an EIN on the process. Here is what to expect:
- Call or visit the bank and tell them you want to open a business account. Ask what documents they need for your business structure (sole proprietor, LLC, partnership, or corporation).
- Gather the documents: your ID, your SSN, your business license or DBA registration, and any articles of incorporation or organization if you have filed them.
- Fill out the business account process. The bank will ask for the business name, address, phone number, and the type of business. They will ask for your SSN in the tax ID field.
- Provide the documents and answer questions about the business. Be ready to explain what the business does and how much money you expect to deposit.
- Sign the account agreement and any other documents the bank requires.
- Deposit the minimum balance if the bank requires one. This varies by bank and account type — some require $100, others require $500 or more.
- If you plan to obtain an EIN later, ask the bank whether you can update the tax ID on the account or whether you will need to close it and open a new one.
What happens when your EIN arrives
Once you receive your EIN from the IRS, contact the bank and ask them to update the tax ID on the account. Some banks do this over the phone or online. Others require you to visit in person with the EIN letter. A few banks will not make the change and will require you to close the account and open a new one — this is rare, but it happens, so ask about it before you open the account.
If the bank requires you to close and reopen, do it as soon as you have the EIN. The longer you wait, the more complicated it becomes, especially if you have already been depositing money and writing checks. The bank will close the old account and open a new one with the same business name and address but a different tax ID. You will get new checks and debit cards, and you will need to update any automatic deposits or payments that were set up on the old account.
Frequently Asked Questions
Can I use my SSN if I have already filed articles of incorporation?
It depends on the bank. Some banks will accept your SSN for a newly incorporated business while you wait for the EIN to arrive. Others require the EIN before opening a business account for a corporation. Call the bank first and ask — if they require an EIN, you can explore for one online at irs.gov and get the number when ready, or explore by mail and wait two to four weeks.
What if the bank says they will not open an account without an EIN?
Try a different bank. Community banks and credit unions are often more flexible than large national banks. You can also explore for an EIN online at irs.gov — it takes about 15 minutes and you receive the number when ready, so you can use that instead of your SSN. If you explore by mail, it takes two to four weeks.
Do I need a business license before I open the account?
Most banks require some proof that the business exists. A business license or DBA registration is the easiest proof. If you do not have one yet, ask the bank what else they will accept — a lease, a utility bill, or articles of incorporation may work. Some banks will accept a letter from you explaining the business if you have nothing else.
Can I use someone else's SSN to open the account?
No. The person whose SSN is on the account must be authorized to sign on the account and must be present when the account is opened. The bank will verify their identity with a government-issued ID. If you are opening the account for a partnership or LLC, the person whose SSN you use must be a partner or member.
Will the bank report my business income to my personal tax return if I use my SSN?
Yes. The bank will report the account activity to the IRS under your SSN, so the income will appear on your personal tax return. Once you obtain an EIN and update the account, future income will be reported under the EIN instead. You may need to file an amended return for the year you used your SSN — talk to a tax professional about this.
