Here’s the exact thing that stopped Marco from opening a business bank account for eight months.

He didn’t know what he needed to bring.

That’s it.

Once your documents are ready, the next choice is where to open — our guide to the best digital banking apps for freelancers narrows it down.

Not laziness. Not procrastination in the usual sense. He’d gone to the Chase website, seen a list of requirements — Articles of Organization, EIN confirmation letter, two forms of ID, proof of business address — and quietly closed the tab. It felt like a project he needed to prep for before starting.

One Tuesday he sat down and just did it. He opened Mercury. Start to finish, 23 minutes. Three things: his EIN, a photo of his driver’s license, and his email address.

That’s the gap. What looks like a bureaucratic process from the outside is actually a 20-minute phone application for most freelancers in 2026. The documents needed to open business bank account are real. The requirements are real. But they’re manageable, and knowing what’s actually on the list is 80% of getting it done.

This checklist breaks it down by business type, by platform, and in the order you should gather things — so you can finish your online account application in one sitting.

Why Platforms Ask for All This — KYC and AML in Plain Terms

Before the list, a quick explanation of the legal reason behind the document requests.

Federal law requires every financial institution to verify who you are before an account opens. Digital or traditional — doesn’t matter. This process has two parts. Know Your Customer (KYC) confirms your identity and your business are real. Anti-Money Laundering (AML) checks that the money flowing through the account isn’t coming from illegal activity. Both are legally mandated compliance requirements.

The difference between traditional banks and digital ones isn’t the process — it’s the speed. A traditional bank has a human reviewing physical documents behind a desk. Digital banks use automated software that reads an ID, matches it to a selfie, validates the business details, and finishes the whole check while you’re still on the last screen of the application. That’s the heart of modern digital bank onboarding.

What KYC compliance checks in practice: your legal name, date of birth, Social Security Number or EIN, and physical address. Plus a match between your ID photo and your face on some platforms. This identity verification step is quick, but it’s non-negotiable. AML checks focus on the nature of your business and expected transaction patterns. Both run automatically. For clean applications, approval lands in minutes.

Most manual review flags happen for the same handful of reasons. Name mismatch between what you typed and what’s on your ID is the biggest one. Using a P.O. Box instead of a physical address is another. Expired ID is the third. All of these are avoidable if you know about them before you start.

What Are the Requirements to Open a Business Bank Account?

Strip away the platform differences and almost every business account comes down to the same short set of requirements. The bank needs to confirm three things: who you are, that your business is real, and how to reach you. Everything on the list below serves one of those goals.

Here’s what you’re actually being asked for:

• A government-issued photo ID. Driver’s license or passport, current and unexpired. This proves who you are.
  
• A tax ID — either an EIN or SSN. Sole proprietors can usually use their Social Security Number. LLCs and corporations need an Employer Identification Number.
  
• Business formation documents. Only if you’ve formed a legal entity. Articles of Organization for an LLC, Articles of Incorporation for a corporation. Sole proprietors skip this.
  
• A physical business address. A real street address, not a P.O. Box, on most platforms. Your home address usually works fine.
  
• A DBA or fictitious-name filing. Only if you operate under a name that isn’t your legal name or your registered entity name.
  
• An opening deposit. Some banks want $0. Others ask for $25 to $100. Digital-first platforms tend to skip this entirely.
  
• Beneficial ownership information. Here’s the one people don’t see coming: if your business has more than one owner, or an owner holding 25% or more, banks are legally required to collect ID details for each of those individuals. A single-member LLC rarely feels this. A three-partner setup does.

The core requirements barely change from bank to bank. What changes is how much proof each provider demands and how quickly they process it. A platform built for solo freelancers may accept your SSN and nothing else. A cross-border account will ask about your expected transaction volume before it approves you. Same underlying requirements — different depth of questioning.

Your Business Structure Changes What You Need

Most freelancers are one of two things: a sole proprietor or an LLC. These have different document requirements, and figuring out what do I need to open a business bank account starts with knowing which category you fall into. We break down the full comparison in sole proprietor vs LLC bank accounts.

Sole Proprietors

Sole proprietor is the simplest setup. Legally speaking, you and the business are the same thing. No separate entity, no state registration needed in most cases. The IRS lets sole proprietors use their Social Security Number as the business tax identifier — an EIN is optional, not required.

Most digital banks accept a sole proprietor account on SSN alone. Some ask for a DBA registration if you operate under a business name rather than your own name — “Marco Creative” instead of “Marco Santos.” A DBA (doing business as) is a simple, inexpensive filing at the county clerk’s office. Many platforms waive the requirement if you apply under your legal name.

If you operate under your own legal name and have no business entity of any kind, sole proprietor banking registration is the fastest path. You’re not forming anything. You’re opening an account under your name for business use.

Opening a Business Bank Account for LLC Owners

An LLC is a separate legal entity. The bank doesn’t just need to verify you — it needs to verify the entity. That’s why setting up a business bank account for LLC owners requires a bit more paperwork than a sole proprietor setup. The platform confirms the company exists, not just the person behind it.

You’ll need your Employer Identification Number (EIN). This is the LLC’s nine-digit tax ID from the IRS. If you don’t have one, you can get it at irs.gov for free. The EIN Assistant takes about 10 minutes and issues the number immediately. Save the PDF confirmation letter — several banks ask for it during EIN verification at onboarding.

You’ll also need your Articles of Organization. This is the state-filed document that created your LLC. Most states issue it as a PDF through the online business filing portal. Find these LLC formation documents now, before you start an application. Trying to locate a file mid-application while a form is sitting open is more stressful than it needs to be.

Some platforms also ask for an Operating Agreement. Not all of them. Mercury and Relay tend to request it for LLCs. It’s the internal governance document that describes how the LLC is managed. If you used LegalZoom or a similar service to form the LLC, it’s in your account. If you don’t have one, templates are available and the document can be created after the fact — though some banks want to see a signed, dated version.

The Complete List of Documents Needed to Open Business Bank Account

Here’s the full rundown, sorted by business type so you can gather everything in one pass.

For Sole Proprietors

Government-issued photo ID comes first. Driver’s license or passport, current and unexpired. The photo needs to be clear enough for automated facial matching. An ID that’s faded, physically damaged, or past its expiration date will fail the check and push the application to manual review.

Social Security Number gets entered directly into the application form — not uploaded as a document or card photo, just typed in. The platform uses it for identity verification and for tax reporting.

Your email address and phone number are standard registration fields. Some platforms set up two-factor authentication immediately on signup using the phone number.

Business name is only an issue if you invoice clients under a different name than your own. If you bill as “Marco Creative” rather than “Marco Santos,” some platforms want to see a DBA registration from your county clerk’s office. Many platforms waive this entirely if you apply under your legal name. Check before you start.

Physical mailing address — must be a real street address, not a P.O. Box, on most platforms. Home address works. Virtual office addresses are accepted by some platforms and not others. This proof of address step is worth c

For LLCs, add these to the list:

EIN — nine-digit IRS tax ID for the LLC. Free to get at irs.gov, takes about 10 minutes, issued immediately. The banks want the PDF confirmation letter, not just the number you have memorized.

Articles of Organization — the state-filed document that created the LLC. It’s usually a PDF sitting in your state’s online business registry. Find and download it before you start the application.

Operating Agreement — required by Mercury and Relay, not required by others. If you used LegalZoom or an attorney to form the LLC, this document is somewhere in your account or files. If you genuinely don’t have one, templates exist and it can be drafted after the fact — but some banks insist on a signed and dated version.

Physical business address — home address is fine. Needs to be real and physical.

What to Bring When Opening a Business Bank Account

You don’t need a folder of paperwork. You need a few files ready before you start, so the application doesn’t time out while you hunt for something. Here’s the short version, split by how your business is set up.

If you’re a sole proprietor, have ready:

• Your driver’s license or passport (photo-ready on your phone)
• Your SSN or EIN
• Your DBA certificate — only if you bill under a business name
• Your home or business street address

If you have an LLC, add:

• Your EIN confirmation letter (the PDF from the IRS, not just the number)
• Your Articles of Organization
• Your Operating Agreement — Mercury and Relay tend to ask; others often don’t
• A photo ID for each owner if it’s a multi-member LLC

One practical move: open your state’s business registry and your IRS confirmation email in separate browser tabs before you begin. The most common stall isn’t a missing document — it’s a document you own but can’t find fast enough while a form sits open and ticking toward a timeout.

What Each Platform Actually Requires

Every platform sets its own requirement to open a business bank account, so the exact list shifts a little depending on where you apply for your business checking account.

Mercury

The application is entirely online. You enter your EIN or SSN, basic business details, and upload a government-issued ID. For LLCs, Articles of Organization are required — that’s how Mercury verifies the entity is real and not just a name on a form. Operating Agreement is usually requested for multi-member LLCs and sometimes for single-member ones too. Approval is typically same-day.

Found

This platform was specifically built for sole proprietors and 1099 contractors. If you’re a sole proprietor, you need your SSN and that’s mostly it — no formation documents. EIN is optional but worth having for tax purposes. The application runs on mobile and takes about 15 minutes.

Relay

Works for both sole proprietors and LLCs. Sole proprietors apply with SSN. LLCs need EIN plus Articles of Organization. An Operating Agreement gets requested sometimes — not always, but Relay’s onboarding process is more thorough than most platforms. Manual review for LLC accounts comes up fairly often and adds a day or two. The 20-account structure on the other side is worth the extra day.

Bluevine

Accepts sole proprietors, LLCs, and some corporations. LLCs need an EIN. The identity check includes a government ID and sometimes a selfie for biometric matching. Bluevine is one of the few digital banks that accepts physical cash deposits, which is why the know your customer process is slightly more detailed than platforms that only handle digital transactions.

Lili

Built specifically for gig workers and solo freelancers. Sole proprietors apply with SSN, no formation documents needed. Mobile-only application with no desktop version. Runs 10 to 15 minutes. Once approved, a virtual card gets issued immediately so you can start business purchases before the physical card shows up in the mail.

Airwallex

More involved than the US-focused platforms because it’s built for international operations. The anti-money laundering requirements for cross-border accounts are stricter than domestic ones. You’ll need a government ID, proof of address documentation, and details about the nature of your business and expected transaction volumes. Allow 24 to 48 hours for approval rather than expecting same-day.

Each of these is covered in our guide to free business bank accounts for freelancers.

How to Open a Business Bank Account

Once you understand the flow, the whole thing is a sequence you can finish in one sitting. Follow it in this order and nothing stalls.

Turn on two-factor authentication the moment the account opens. Before you add money, before you connect a single client. It takes 90 seconds and it’s the strongest protection you have against unauthorized access.

Pick your bank or fintech first. Match the provider to your setup. Solo and 1099? Found or Lili. Running an LLC? Mercury or Relay. Handling international payments? Airwallex. Choosing first saves you gathering documents a platform doesn’t even ask for.

Gather everything before you open the application. Your ID, your EIN or SSN, and any formation documents. Save them as phone photos or PDFs. Hunting for a file mid-application is the single most avoidable frustration here.

Type your details exactly as they appear on your documents. Name, business name, address — all of it must match your ID and EIN letter. A small mismatch between what you type and what your paperwork says is the number-one reason clean applications get flagged.

Photograph your ID in good light. Face a window. Dark or blurry ID shots fail the automated check and bump you into manual review, which adds days.

Submit on WiFi, not mobile data. Banking applications time out when a connection drops, and a lost connection usually means starting over from scratch.

Watch your email for the first hour. Approval notices and verification links arrive by email. Mark the bank’s domain as safe first, or the notification lands in spam while you wonder why nothing happened.

Respond fast if you’re asked for anything else. If the account goes to manual review, provide exactly what’s requested — not more, not less. Most clean freelance applications close within two business days.

If Your Application Gets Flagged

Manual review is more common than most people expect. It’s not a rejection. It means a human needs to look at something before the account opens.

The most common reasons: your name appears differently across documents, your address doesn’t match what public records show, your business was formed very recently and has no history, or your business category falls into a higher-scrutiny segment — crypto and lending get flagged more than graphic design and copywriting.

When you’re contacted, respond quickly and provide exactly what was requested. Not more, not less. Manual reviews for most clean freelance businesses close within two business days.

People Also Ask – PAA’s

What are the documents needed to open business bank account online?

Sole proprietors need a government-issued ID and their Social Security Number. LLCs need an EIN, Articles of Organization, and sometimes an Operating Agreement. Most platforms also need a physical business address and a business name if you operate under one. Found and Lili have the lightest requirements. Mercury and Relay are slightly more thorough for LLC accounts. Those are the core requirements of opening a business bank account, and they rarely change much from platform to platform.

Should I use an EIN or SSN to register a freelancer bank account?

Sole proprietors can use their SSN and most digital banks accept it. If you’re an LLC, use your EIN — it keeps your Social Security Number out of business transactions and adds a layer of identity protection. Getting an EIN is free and takes 10 minutes at irs.gov. Even sole proprietors benefit from having one because it means you stop sharing your SSN on client 1099 forms.

How long does digital business banking onboarding take?

Sole proprietors applying to Found, Lili, or Mercury with all documents ready: 10 to 25 minutes. LLC applications with Articles of Organization and Operating Agreement: 30 to 45 minutes. Approval is same-day on most platforms. Airwallex takes 24 to 48 hours.

Can I get an instant-use virtual card when the account opens?

Yes, on several platforms. Lili issues one immediately after approval. Mercury issues a virtual card alongside the physical card order. Found also provides immediate digital access. If getting a card fast matters to you, confirm with the specific platform before you apply — some issue them instantly and some don’t.

Can I open a business bank account with my Social Security number?

Yes. If you’re a sole proprietor, most digital banks let you open a business bank account using just your SSN — no EIN, no formation documents. LLCs and corporations are different; they almost always need an EIN because the bank is verifying a separate legal entity, not just a person. Here’s the honest advice even for sole proprietors: get an EIN anyway. It’s free at irs.gov, it takes ten minutes, and it means you stop handing your Social Security Number to every client filling out a 1099.

What documents do I need to open a business bank account for an LLC?

An LLC needs a bit more than a sole proprietor because the bank has to confirm the company exists. You’ll typically need your EIN confirmation letter, your Articles of Organization, a government-issued photo ID, and often an Operating Agreement — Mercury and Relay usually ask for one, while lighter platforms may not. If your LLC has more than one member, expect the bank to collect ID details for each owner. Gather the formation files before you start; locating a state-filed PDF mid-application is where most people lose momentum.

How do you open a business checking account?

The process is the same whether a bank calls it a business bank account or a business checking account. Pick a provider that fits your business type, gather your ID and tax ID, prepare any formation documents, then complete the online application and verify your identity. Sole proprietors with everything ready can finish in 10 to 25 minutes. LLC applications with formation documents run closer to 30 to 45 minutes. Most platforms approve the same day.

Do all banks require the same paperwork for business account opening?

No, and assuming they do is where people get caught out. The core requirements are consistent — ID, a tax ID, formation documents for registered entities, and a physical address. But the depth varies a lot. A platform built for freelancers might accept your SSN and stop there. A bank that handles cash deposits or cross-border transfers will ask more questions about your business and expected transaction patterns before approving. Same foundation, very different levels of scrutiny. Always check the specific provider’s list before you apply, because that’s the version that actually decides your approval.

What Marco Found Out

He applied on a Tuesday. The account was open before dinner.

His EIN was in an email from when he’d filed for it. His driver’s license was in his wallet. He photographed it with his phone. Uploaded it. Typed in his information. Done.

He told me the thing that surprised him most wasn’t how fast it was. It was how small the list actually was. He’d been picturing something much more complicated based on looking at a traditional bank’s requirements page.

Digital bank onboarding is genuinely simpler than that. When you know the documents needed to open business bank account, you can open a business bank account online in under an hour. One of the biggest benefits of a business account is what comes out the other side: cleaner finances, easier taxes, and a happier accountant.

Those benefits only hold when money stays apart, which is why a separate freelancer bank account matters from day one.

The only actual obstacle is starting. Gather your ID, your EIN or SSN, and any LLC formation documents today — then pick a platform from the list above and knock out the application before your next coffee gets cold.
