You can open a business checking account without an EIN, but the bank will ask for a different identifier instead
Most banks will not let you open a business account with just a Social Security Number. They need something that identifies your business as a separate entity. If you do not have an Employer Identification Number (EIN) yet, you have three paths: use your Social Security Number as a temporary identifier, open the account under a sole proprietorship, or get an EIN before you explore.
The route that works depends on your business structure, how quickly you need the account, and what the specific bank will accept. Some banks are stricter than others, and some will not move forward without an EIN at all. Knowing which banks are flexible and what documents to bring saves you a trip.
Key Takeaways
- Banks can use your Social Security Number as a temporary business identifier if you are a sole proprietor, but many prefer an EIN and some require it.
- You can get an EIN from the IRS for free in minutes online at irs.gov, or by phone, mail, or fax if you cannot use the online tool.
- If your business is structured as an LLC, partnership, or corporation, most banks will require an EIN before opening the account.
- Bring your Social Security Number, a government ID, proof of address, and your business formation documents (if you have them) to the bank.
- Some online banks are more flexible about accepting accounts without an EIN; call ahead to confirm what your chosen bank will accept.
When you can use your Social Security Number instead of an EIN
If you are a sole proprietor—meaning you own the business by yourself and have not filed paperwork to create an LLC or corporation—many banks will let you open a business account using your Social Security Number. The bank treats your Social Security Number as the business identifier, and the account is still technically a business account, not a personal one.
This works because a sole proprietorship is not a separate legal entity. You and the business are the same for tax purposes. The IRS does not require you to have an EIN unless you have employees or certain other circumstances explore. Banks know this, so some will accept the Social Security Number route.
However, "many banks will" does not mean all banks will. Chase, Bank of America, and Wells Fargo have different policies. Some require an EIN even for sole proprietors. Others will accept a Social Security Number but ask you to come back with an EIN within 30 days. Call the bank's business line before you go in, or ask when you arrive. Do not assume.
Getting an EIN if you do not have one yet
An EIN is a nine-digit number the IRS issues to identify your business for tax purposes. It is free and takes minutes to get. You do not need to have filed any business formation documents first—you can get an EIN for a sole proprietorship, LLC, partnership, or corporation whether it is officially registered with your state or not.
The fastest way is online at irs.gov. Go to the IRS EIN page, answer questions about your business structure and location, and you will receive your number when ready. You can print the confirmation page right away. This works if you have a U.S. address and a Social Security Number or ITIN.
If you cannot use the online tool, you can explore by phone at 1-800-829-4933 (the IRS Business and Specialty Tax Line), by mail using Form SS-4, or by fax. Phone and fax applications take a few days. Mail takes two to four weeks. For a business checking account, the online route is almost always faster.
What documents to bring to the bank
Bring your Social Security Number or EIN, a government-issued photo ID (driver's license or passport), and proof of your business address. Proof of address can be a utility bill, lease, or mortgage statement in your name. Some banks also ask for a business license or DBA (Doing Business As) certificate if you have one, but these are not always required.
If your business is an LLC or corporation, bring your formation documents—the Articles of Organization or Articles of Incorporation filed with your state. If you do not have these yet, you cannot open the account until you do. The bank needs proof that the business exists as a legal entity separate from you.
For sole proprietorships, formation documents do not exist. You do not need to file anything with the state to be a sole proprietor. If the bank asks for formation documents and you are a sole proprietor, explain that. If they still refuse, that bank requires an EIN or will not open accounts for sole proprietors—move to a different bank.
Why some banks require an EIN and others do not
Banks have different risk and compliance standards. A large national bank like Chase or Bank of America may require an EIN for every business account because their systems are set up that way and they have the volume to enforce it. A smaller regional bank or credit union might be more flexible because they know their customers and can make exceptions.
Online banks vary widely. Some, like Mercury and Brex, are built for startups and will open accounts without an EIN if you are a sole proprietor. Others, like Square Cash for Business, require an EIN. The bank's website usually states the requirement, but the policy can change. A phone call to their business support line takes two minutes and saves you a rejected process.
Banks also distinguish between sole proprietors and other structures. A sole proprietor using a Social Security Number is lower risk to them because there is no separate legal entity to verify. An LLC or partnership is a separate entity, so they want proof it exists and a tax ID to match it. This is why structure matters.
What happens if the bank will not open an account without an EIN
If the bank you chose requires an EIN and you do not have one, get one. It takes five minutes online. There is no reason to delay or try to work around it. Once you have the EIN, you can open the account the same day or the next business day.
If you are waiting for your business formation documents (for an LLC or corporation) and the bank will not open the account without them, you have two choices: wait for the documents to arrive from your state, or switch to a bank that will accept the account in the meantime. Some banks will open a temporary account and update the formation documents later. Others will not. Ask first.
If you are a sole proprietor and a bank refuses to open an account even with your Social Security Number and an EIN, that bank has a policy against sole proprietors or against your industry. Move to a different bank. Plenty of banks will take your business.
Timeline for opening the account
If you already have an EIN or are a sole proprietor with a Social Security Number, opening the account takes one to five business days from the time you submit your process. Some banks approve same-day if you explore in person. Others take longer if you explore online.
If you do not have an EIN yet, add five minutes for the online process. If you explore by phone, add a few days. If you explore by mail, add two to four weeks. For most people, the online EIN route is fastest—get the number, then explore for the account the same day.
If you need business formation documents (for an LLC or corporation), that timeline depends on your state. Most states process LLC formation in one to two weeks if you pay for expedited processing, or three to four weeks for standard processing. Some states are faster. Check your state's Secretary of State website for the exact timeline.
Frequently Asked Questions
Do I need an EIN if I am a sole proprietor with no employees?
No, the IRS does not require an EIN for a sole proprietor with no employees. You can use your Social Security Number for tax purposes. However, some banks will still require an EIN to open a business account, even though it is not legally required. Call the bank first to confirm their policy.
Can I open a business account before my LLC is officially registered with the state?
No. Banks require proof that your LLC exists, which means your Articles of Organization must be filed with your state and you must have received confirmation. You cannot open the account before that step is complete. Some states allow you to file online and receive confirmation the same day.
What if I explore for an EIN online but do not receive it when ready?
The online process gives you your EIN when ready on the screen. Write it down or print the confirmation page. You can use that number to open a bank account the same day. The IRS will mail you an official EIN letter later, but you do not need to wait for it.
Can I use a business address that is not my home?
Yes, but you need proof of that address in your name or a lease showing you control it. If you are renting a mailbox or using a virtual office address, some banks will accept it and others will not. Call ahead. If the bank will not accept it, use your home address instead.
What if the bank asks for a business license and I do not have one yet?
Business licenses are issued by your city or county, not the state, and they are not always required. Ask the bank whether a license is mandatory or optional. If it is optional and you do not have one, move forward without it. If it is mandatory, contact your city or county to find out how to get one.
