You need a legal business structure and an EIN before most banks will open a business account
A business checking account requires proof that your business actually exists as a legal entity. Banks will not open an account for "my side hustle" or "my idea." You need either a registered business structure (sole proprietorship, LLC, S-corp, C-corp, partnership) and a federal Employer Identification Number (EIN), or in some cases, just a sole proprietorship with your Social Security number. The specific requirements vary by bank and by what type of business you are running.
The order matters: you register your business structure first, get your EIN second, then approach banks with both documents. Trying to open an account before you have these in place will result in rejection, and you will have wasted the bank's time and yours.
Key Takeaways
- Most banks require an EIN and proof of business registration before opening a business checking account, though sole proprietors can sometimes use their Social Security number instead.
- You must register your business structure with your state before explore for an account — this is a separate step from getting an EIN.
- The IRS issues EINs for free through their website or by phone, and you can have one the same day you explore.
- Bring your EIN letter, business registration documents, and a government-issued ID to the bank; some banks also ask for a business license or articles of organization.
- Online banks and community banks often have fewer documentation requirements than large national banks, though all require some proof of legal business existence.
What counts as a legal business structure
A legal business structure is the form your business takes in the eyes of the law. The most common are sole proprietorship, LLC (limited liability company), S-corp, C-corp, and partnership. Each one is registered differently and has different tax and liability consequences, but for the purpose of opening a checking account, what matters is that you have registered it with your state.
A sole proprietorship is the simplest: you register a business name (called a DBA, or "doing business as") with your county or state, and that is your structure. An LLC requires filing articles of organization with your state's secretary of state office. An S-corp or C-corp requires filing articles of incorporation. A partnership requires a partnership agreement and registration with your state.
You do not need to have chosen the most tax-efficient structure or the one that makes the most sense for your long-term plans. You need the one that is actually registered. If you have not registered anything yet, start with your state's secretary of state website — it will tell you exactly what to file and where to send it.
How to get an EIN and what it is
An EIN (Employer Identification Number) is a nine-digit number the IRS assigns to your business. It works like a Social Security number for your business — banks use it to verify that your business is real and to report interest earned on the account. You do not need to have employees to get one; sole proprietors, LLCs, and corporations all get EINs.
You can get an EIN for free from the IRS in three ways: online at irs.gov (takes about 15 minutes and you get the number when ready), by phone at 1-800-829-4933 (takes about 10 minutes), or by mail (takes two to four weeks). Most people use the online method because it is fastest. You will need your Social Security number, your business structure type, and your business address.
The IRS will give you a confirmation number on the spot and will email you a copy of your EIN letter within a few days. Print that letter or save it as a PDF — banks will ask for it. If you applied online and do not see an email within a week, you can call the IRS and ask them to resend it.
What documents to bring to the bank
Different banks ask for different documents, but the core set is the same. You will need your EIN letter from the IRS, your business registration documents (the certificate of formation, articles of organization, or DBA registration — whatever your state issued), and a government-issued photo ID. Some banks also ask for a business license, though not all states require one.
If you registered an LLC, bring your articles of organization. If you registered a corporation, bring your articles of incorporation. If you registered a sole proprietorship, bring your DBA certificate. If you are not sure what you registered or where to find the document, call your state's secretary of state office — they can tell you what you filed and can usually send you a certified copy for a small fee.
A few banks ask for additional items: proof of your business address (a utility bill or lease in the business name), a business plan or description of what the business does, or a personal credit report. These are less common, but if a bank asks for them, they are usually trying to verify that you are not opening the account for money laundering or fraud. Bring what they ask for.
Sole proprietors and Social Security numbers
If you registered a sole proprietorship and have not gotten an EIN, some banks will let you open a business account using your Social Security number instead. This is more common at community banks and online banks than at large national chains. However, the trend is moving toward requiring an EIN even for sole proprietors, so getting one is safer.
The advantage of using your Social Security number is speed — you do not have to wait for an EIN letter. The disadvantage is that your personal credit and business credit become harder to separate, and if you ever want to hire employees or take on business debt, you will need an EIN anyway. Most accountants recommend getting an EIN even if you do not strictly need one yet.
Why banks reject business account applications
The most common reason a bank rejects a business account process is that the applicant has not registered the business with the state. The second most common is that the documents do not match — for example, the business name on the registration does not match the name on the EIN letter, or the address is different. The third is that the applicant has a history of fraud or financial crime, which shows up on a background check.
If a bank rejects you, ask them why. If it is a documentation mismatch, you can usually fix it by getting a corrected document from the state or the IRS. If it is a background issue, you may need to try a different bank — some are stricter than others. If it is because you have not registered your business, register it first and then reapply.
Online banks versus in-person banks
Online banks often have simpler documentation requirements than brick-and-mortar banks. Many will let you upload your EIN letter and business registration documents directly through their website and open an account in a few days without speaking to anyone. In-person banks usually require you to visit a branch, speak to a banker, and sometimes provide additional documentation on the spot.
The trade-off is that online banks cannot help you troubleshoot if something goes wrong with your process, and they cannot override their system if a document is slightly wrong. In-person banks have more flexibility. If you are organized and your documents are in order, an online bank is usually faster. If you are unsure whether your documents will be accepted, an in-person bank gives you a chance to ask before you submit anything.
Frequently Asked Questions
Can I open a business checking account without registering my business first?
No. Banks verify that your business is legally registered before opening an account. If you have not registered with your state, register first. This takes a few days to a few weeks depending on your state and whether you file online or by mail.
Do I need an EIN if I am a sole proprietor?
Not always — some banks will let you use your Social Security number instead. However, getting an EIN is free and takes 15 minutes online, and it keeps your personal and business finances more separate. Most accountants recommend getting one even if your bank does not require it.
How long does it take to get an EIN?
If you explore online or by phone, you get your EIN when ready. If you explore by mail, it takes two to four weeks. The IRS will email you a confirmation letter within a few days of online or phone process.
What if my business registration and EIN have different addresses?
Contact the IRS or your state to correct one of them before you explore to the bank. Banks will reject applications where the documents do not match. The IRS can update your address quickly if you call them; your state may take longer.
Can I open a business account if I have bad personal credit?
Most banks do a background check but do not check your personal credit score for a business account. They check for fraud, unpaid judgments, and financial crime. Bad credit alone usually will not disqualify you, but fraud or unpaid debts to banks will.
