Yes, you can open a corporate bank account online, but the process is slower and more document-heavy than opening a personal account
Most banks now let you start a corporate account application online, but you will hit a wall partway through. The bank will ask for your Employer Identification Number (EIN), articles of incorporation or formation documents, proof of business address, and often a government ID for each owner or authorized signer. Some banks complete the whole process online; others require you to print, sign, and mail documents or visit a branch in person. The timeline ranges from same-day approval (rare) to two to three weeks, depending on the bank and how quickly you gather paperwork.
The reason it takes longer than personal banking is that banks must verify your business exists and is registered with your state. They also run background checks on owners and signers. If your business is brand new or your ownership structure is complex, expect delays.
Key Takeaways
- You will need your EIN, articles of incorporation or formation, and proof of business address before you start any online application.
- Some banks complete the entire process online; others require you to mail signed documents or visit a branch to finish.
- Approval typically takes one to three weeks because the bank must verify your business registration with your state.
- Banks require government ID from all owners, all members of an LLC, or all authorized signers, depending on your business structure.
- Online applications are faster than walking into a branch, but slower than opening a personal account at the same bank.
What documents you need before you apply
Gather these before you click the first button on any bank's website. Having them ready cuts your approval time in half.
Your EIN is the nine-digit number the IRS assigns to your business. If you have not received one yet, you can get it the same day by applying online at irs.gov. The application takes about 15 minutes. If you are a sole proprietor and have not formed an LLC or corporation, you may be able to use your Social Security number instead, but most banks prefer an EIN.
Articles of incorporation or formation are the state documents that officially register your business. If you formed an LLC, you have articles of organization. If you formed a corporation, you have articles of incorporation. If you formed a partnership, you have articles of partnership. The bank will ask for a certified copy — meaning a copy stamped by your state's secretary of state office. You can usually order this online from your state's website for $5 to $25. It arrives by mail in one to two weeks, so order it now if you do not have it.
Proof of business address is usually a utility bill, lease agreement, or mortgage statement in your business name. If your business is brand new and you do not have a bill yet, a signed lease or a letter from your landlord works. If you work from home, a utility bill with your home address and the business name on it is acceptable at most banks.
Government ID for owners and signers — the bank will ask for a driver's license or passport for every owner (if you are a sole proprietor), every member (if you are an LLC), or every authorized signer you name. Have these ready before you apply.
Which banks let you complete the entire process online
A handful of banks finish corporate accounts entirely online without requiring you to mail or sign anything in person. These are the exception, not the rule.
Mercury and Brex are designed for startups and small businesses and complete most applications online. Both are fintech banks (not traditional banks), so they do not have physical branches. Mercury typically approves accounts within one business day if your documents are in order. Brex takes two to three business days. Both charge no monthly fee and offer no physical debit cards by default, though Brex offers one for a fee.
Square Cash for Business and Stripe Connect are not full bank accounts but business payment accounts that let you receive money and pay bills. They are faster to open (often same-day) but do not offer the same features as a real bank account, such as a business debit card or the ability to deposit checks.
Traditional banks like Chase, Bank of America, and Wells Fargo let you start the application online, but most require you to mail in signed documents or visit a branch to finish. Chase's online process takes about 10 minutes, but approval takes one to two weeks after you submit your documents. Some Chase branches will complete the account in person the same day if you bring everything with you.
What happens after you submit your application online
After you hit submit, the bank's compliance team reviews your documents. They are checking that your business is registered, that the owners are who they say they are, and that none of the owners appear on government watchlists. This is called Know Your Customer (KYC) verification.
If the bank approves you, you will receive an email or call with your account number and routing number. At this point, you can start using the account — you can receive wire transfers and ACH deposits immediately. If you need a debit card or checks, those ship separately and arrive in five to ten business days.
If the bank asks for more information, they will email you a list of what they need. Common requests are a second form of ID, a more recent utility bill, or clarification on who the true owner of the business is. Respond within the timeframe they give you (usually five to ten business days), or your application will be denied and you will have to start over.
When the bank requires you to visit a branch or mail documents
Most traditional banks require at least one of these steps. Some let you mail everything; others require you to appear in person.
If the bank asks you to mail documents, they will send you a list of what to mail and where to send it. You typically mail a certified copy of your articles of formation, a government ID for each owner, and a signed resolution authorizing the account (the bank provides a template). Mail it certified with return receipt so you have proof it arrived. The bank processes it within five to ten business days after they receive it.
If the bank requires you to visit a branch, bring originals of everything: your articles of formation, government IDs for all owners, proof of business address, and your EIN documentation. A bank officer will verify the documents, take copies, and you will sign the account agreement in front of them. This usually takes 15 to 30 minutes. Approval happens the same day or within one business day.
Why some applications get delayed or denied
The most common reason for delay is incomplete or outdated documents. If your articles of formation are more than a few months old and your business address has changed, the bank may ask for an updated certificate of good standing from your state. This costs $5 to $25 and takes one to two weeks to arrive.
The second most common reason is a mismatch between the name on your articles and the name you are using for the account. If you formed an LLC called "Smith Consulting LLC" but you are trying to open the account under "Smith Consulting," the bank will flag it. Use the exact legal name from your articles.
Background checks can also cause delays. If any owner has a criminal record or appears on a government sanctions list, the bank will either deny the account or ask for more information. This is not automatic disqualification — the bank will contact you to discuss it.
New businesses sometimes get denied because they have no business history or tax returns. If this happens to you, try a bank that specializes in startups, such as Mercury or Brex, or ask a traditional bank whether they will approve the account if you make an initial deposit of $5,000 or more.
How long it actually takes, start to finish
The timeline depends on which bank you choose and whether you have all your documents ready before you start. If you need to order a certified copy of your articles of formation, add one to two weeks. If you need to get an EIN, add one day (if you apply online) or two to three weeks (if you apply by mail).
| Bank Type | Application Time | Approval Time | Total Time |
|---|---|---|---|
| Fintech (Mercury, Brex) | 10–15 minutes | Same day to 3 business days | 1–3 business days |
| Traditional bank (online only) | 10–20 minutes | 5–10 business days | 5–10 business days |
| Traditional bank (mail documents) | 10–20 minutes | 5–10 business days after receipt | 10–20 business days |
| Traditional bank (in-person) | 15–30 minutes in branch | Same day to 1 business day | 1 business day |
The fastest route is a fintech bank if you have all documents ready and your business structure is straightforward. The slowest is a traditional bank that requires mailed documents, especially if you need to order a certified copy of your articles first. In-person at a branch is fastest for traditional banks if you can visit one.
Frequently Asked Questions
Can I open a corporate account if my business is not registered yet?
No. Banks require proof that your business is registered with your state. If you have not filed your articles of formation or incorporation yet, do that first. It takes one to two weeks in most states and costs $50 to $300 depending on your state and business type.
Do I need an EIN if I am a sole proprietor?
Not always. Some banks let sole proprietors use their Social Security number instead. However, an EIN keeps your personal and business finances separate in the IRS's records and is free to get. Most accountants recommend getting one even if the bank does not require it.
What if I do not have a business address yet?
Many banks accept a home address if you work from home. If you do not have a permanent address, some banks will accept a virtual office address or a UPS mailbox address, though this varies by bank. Call the bank before you apply to ask whether they accept it.
Can I open the account if I am not the owner?
No. The person opening the account must be an owner or authorized signer. If you are an employee opening the account on behalf of the owner, the owner must be present (in person or by signing documents) to authorize it.
What if the bank denies my application?
Ask the bank why. Common reasons are incomplete documents, a mismatch in business names, or a background check issue. You can reapply after fixing the problem, or try a different bank. Fintech banks are often more flexible with new or unusual business structures.
