Not every business checking account can be opened entirely online, and the ones that can have different requirements depending on your business structure and the bank

Most large national banks now let you start a business checking account online, but the process stops short of completion for many account types. You'll typically fill out an application, verify your identity, and fund the account through your browser — but then you may need to mail in documents, visit a branch, or wait for a callback before the account is actually active. Some banks, particularly online-only banks and credit unions, complete the entire process digitally. Others require you to show up in person or send original documents by mail.

The speed and ease of opening online depends on three things: your business structure (sole proprietorship, LLC, S-corp, or C-corp), whether the bank has your state's charter, and whether you already have a personal account there. A sole proprietor opening an account at a bank where they already bank personally will have the fastest online experience. An LLC opening at a bank for the first time, or a corporation of any kind, will almost certainly hit a step that requires paperwork or a phone call.

Key Takeaways

  • Online-only banks and some credit unions complete the entire business checking setup digitally, while most traditional banks require you to mail documents or visit a branch to finish.
  • Sole proprietors can often open accounts entirely online if they already have a personal account at that bank, but LLCs and corporations usually need to provide formation documents.
  • Banks verify your identity online but still require original or certified copies of your EIN letter, articles of incorporation or organization, and business license before the account goes live.
  • The fastest route is usually a bank where you already have a personal account, because they already have your identity verified and can cross-reference your information.
  • Credit unions often have simpler online processes for small businesses but may have membership requirements or geographic restrictions.

What banks will let you complete entirely online

Online-only banks like Novo, Mercury, and Brex typically let you open a business checking account from start to finish without leaving your computer. They use digital identity verification, accept photos of your documents, and can fund the account the same day or within one business day. These banks are built for remote operation and don't have the compliance overhead of traditional banks with physical branches.

Some credit unions also offer fully online business checking, though you may need to become a member first — which itself can be done online if you meet their field of membership rules (often based on geography, employer, or family connection). Credit unions typically have lower fees than traditional banks and simpler document requirements for small businesses.

A handful of traditional banks — including some regional banks and a few large ones — have streamlined their online process enough that sole proprietors can complete it entirely digitally. Chase, for example, lets sole proprietors open online if they already have a personal Chase account, but LLCs and corporations still need to mail in documents. Bank of America has a similar policy. The exact rules change by bank and by state, so you need to check the specific bank's website or call to confirm.

What documents you'll need to provide, and how

The documents required depend on your business structure. A sole proprietor typically needs a Social Security number, a driver's license or passport, and proof of a business address (utility bill, lease, or mortgage statement). Some banks skip the business address if you use your home address. If you have an EIN, you can provide it, but it's not required for a sole proprietor.

An LLC or corporation needs your EIN letter (from the IRS), articles of organization or incorporation (from your state), a business license if your state or city requires one, and identification for the person signing the account agreement. Many banks also ask for a resolution or certificate of good standing from your state's Secretary of State office. Online banks accept photos or scans of these documents. Traditional banks often require original or certified copies, which means you'll need to mail them in or bring them to a branch.

The EIN letter is the document that proves you have an EIN and shows the IRS's record of your business name and structure. You can download it from the IRS website if you already have an EIN, or request it by mail or phone. If you don't have an EIN yet, you can apply for one online at the IRS website — it takes about 15 minutes and you get a confirmation number immediately, though the official letter arrives by mail in about two weeks. Some banks will accept the confirmation number temporarily while you wait for the letter.

Why traditional banks often require a branch visit or mailed documents

Large banks with physical branches have compliance requirements that online-only banks don't face. They're required to verify your identity in person or through a notarized document for certain account types, and they need to confirm that the person opening the account actually has authority to do so. For a corporation, that means verifying the signatory's role. For an LLC, it means confirming the member or manager opening the account has the right to bind the business.

These requirements exist to prevent fraud and money laundering, and they're enforced by federal banking regulators. A traditional bank can't skip them just because you'd prefer to stay online. Some banks have found workarounds — video verification with a notary, for example — but most still require either a branch visit or mailed documents for anything beyond a sole proprietor account.

How long the process takes if you go online

If you choose an online-only bank and have all your documents ready, the account can be open and funded within 24 hours. Novo and Mercury typically fund accounts the same day you're approved. Brex takes one to two business days.

If you're opening at a traditional bank that requires mailed documents, add 5 to 10 business days for mail delivery, plus 3 to 5 business days for the bank to process and verify the documents. That puts you at roughly two to three weeks from application to active account. If you visit a branch in person, the process is usually faster — often the same day or the next business day — because the bank can verify documents and your identity immediately.

Credit unions vary widely. Some can open accounts within 24 hours if you're already a member and have all documents ready. Others take a week or more. Call ahead to ask about their timeline.

When you should choose an online bank versus a traditional bank

Choose an online-only bank if you want the fastest setup, don't need a physical branch, and are comfortable managing your account entirely through an app or website. Online banks typically have lower fees and simpler interfaces. They're good for startups, freelancers, and small businesses that don't need to deposit cash or checks in person.

Choose a traditional bank if you need to deposit cash or checks regularly, want the option to visit a branch, or prefer working with a human banker. Traditional banks also tend to have higher account limits and more lending options if you plan to grow quickly. The tradeoff is slower online setup and higher fees.

Choose a credit union if you may have access to for membership, want lower fees, and don't mind a smaller institution. Credit unions often have better customer service for small businesses and more flexible lending. The downside is that not all credit unions offer business checking, and some have geographic or membership restrictions.

What to do if the bank won't let you open online

If a bank requires you to visit a branch or mail documents, you have three options: do it their way, choose a different bank, or ask if they have a workaround. Some banks will make exceptions if you call and explain your situation — for example, if you're out of state or unable to visit a branch, they may accept a video call with a notary instead of an in-person visit.

Before you settle on a bank, search for "[bank name] business checking online" and look for their specific policy. Many banks post this information on their website. If you can't find it, call their business banking line and ask directly: "Can I open a business checking account entirely online, or do I need to mail documents or visit a branch?" This saves you time and frustration later.

Frequently Asked Questions

Can I open a business checking account online if I don't have an EIN yet?

Yes, if you're a sole proprietor. You can use your Social Security number instead. If you're an LLC or corporation, you'll need an EIN before you open the account. You can get one online from the IRS in about 15 minutes, though the official letter takes two weeks to arrive by mail. Some banks accept the confirmation number while you wait for the letter.

Do I need to have a personal account at the bank to open a business account online?

Not always, but it helps. If you already have a personal account at the bank, they've already verified your identity and can move faster. Many banks let sole proprietors open business accounts online only if they're existing customers. New customers often need to mail documents or visit a branch, even for sole proprietor accounts.

What if I'm opening an account for an LLC but don't have articles of organization yet?

You need to file your articles of organization with your state before you open a business checking account. The bank will ask for a copy, and you can't get one until the state has processed your filing. File online through your state's Secretary of State website — it usually takes one to five business days. Once you have the filing confirmation, you can apply for the account.

Can I open a business checking account online on a weekend?

You can submit your application online anytime, but the bank won't process it or verify your identity until the next business day. Online-only banks may process applications faster, but traditional banks typically don't process anything on weekends or holidays. Plan for your application to be reviewed on the next business day.

What happens if the bank rejects my online application?

Banks reject applications for reasons like mismatched information, incomplete documents, or compliance concerns. The bank should tell you why. If they do, you can correct the issue and reapply, or try a different bank. If you're unsure why you were rejected, call the bank's business banking line and ask — they can sometimes override a rejection or explain what you need to fix.
