What you need before you walk into a bank
A business bank account requires proof that your business exists as a legal entity separate from you personally. The documents the bank will ask for depend on your business structure — sole proprietorship, LLC, S-corp, C-corp, or partnership — and they vary slightly by bank and state.
At minimum, bring a government-issued photo ID (driver's license or passport), your Social Security number or Employer Identification Number (EIN), and proof of your business name and structure. If you operate as a sole proprietor under your own name, you may only need your personal ID and Social Security number. If you use a business name that differs from your legal name, you'll need a Doing Business As (DBA) certificate or similar registration from your state or county.
For LLCs, S-corps, and C-corps, bring your Articles of Organization or Articles of Incorporation — the document you filed with your state to legally establish the business. You'll also need an EIN, which you can obtain free from the IRS before opening the account. If your business is brand new and you haven't received your EIN yet, some banks will let you apply for the account using your Social Security number temporarily, then update it once the EIN arrives.
Key Takeaways
- Sole proprietors need only a personal ID and Social Security number, while LLCs and corporations must bring Articles of Organization or Incorporation filed with the state.
- An EIN is required for most business structures except sole proprietorships using the owner's Social Security number, and you can obtain one free from the IRS online before opening the account.
- Banks verify your identity and business registration in person or online, a process that typically takes 15 to 30 minutes if all documents are present.
- Monthly fees, minimum balances, and transaction limits vary widely by bank, so comparing options before you open saves money over time.
- You can open an account online with many banks without visiting a branch, though some still require in-person verification for certain business structures.
Getting an EIN if you don't have one yet
An Employer Identification Number is a nine-digit code the IRS assigns to your business. You need one if you have employees, operate as an LLC, S-corp, or C-corp, or plan to hire contractors. Sole proprietors using only their Social Security number do not need an EIN, though many choose to get one anyway for privacy and accounting reasons.
You can obtain an EIN free through the IRS website at irs.gov. Go to the "Apply for an EIN" section and fill out Form SS-4 online. The IRS issues the number immediately — you'll see it on screen and can print it right away. If you apply by mail or fax, the process takes two to four weeks. Do not pay anyone to obtain an EIN for you; the IRS never charges a fee.
Bring your EIN confirmation letter or the number itself when you open the account. If you're opening the account before your EIN arrives, ask the bank whether they'll hold the account open temporarily under your Social Security number and let you add the EIN later.
Choosing between online and in-person opening
Many banks now let you open a business account entirely online, uploading photos of your documents through their website or app. This route is fastest if your business structure is straightforward — a sole proprietorship or a simple LLC — and you have all documents ready. The account typically opens within one to three business days.
Some banks still require at least one in-person visit, especially for corporations or if the account will handle high transaction volume. A few banks require the business owner to appear in person to verify identity, even if you start the application online. Call the bank before you begin to confirm whether your business structure can open fully online or whether you'll need to visit a branch.
Online opening is convenient if you live far from a branch or have a busy schedule. In-person opening lets you ask questions about fees and features face-to-face and sometimes negotiate terms with a banker. Choose based on your timeline and comfort level with digital paperwork.
What happens during the verification process
Once you submit your documents, the bank verifies that your business is registered with the state and that you are who you say you are. They cross-check your ID against government databases and confirm your business structure through state records. This verification usually takes 24 to 48 hours for online applications and happens immediately if you open in person.
The bank may also run a background check or review your personal credit history, depending on the account type and the bank's policy. This does not affect your credit score. If the bank finds any discrepancies — a name mismatch, a registration that hasn't been filed yet, or an address that doesn't match your ID — they will contact you to clarify before opening the account.
Once verification is complete, the account opens and you receive account details, routing number, and account number. You can begin depositing funds and writing checks immediately, though some banks hold the first deposit for one to two business days as an additional security measure.
Comparing fees and account features
Business bank accounts are not one-size-fit-all. Monthly maintenance fees range from zero to $25 or more, depending on the bank and account tier. Some banks waive the fee if you maintain a minimum balance (often $1,000 to $10,000) or set up direct deposit. Others charge per transaction — per check written, per deposit, per wire transfer — while some include a set number of transactions free each month.
Before opening, compare three to five banks on these points: monthly fee structure, minimum balance requirement, number of free transactions per month, check printing costs, wire transfer fees, and whether they offer online banking and mobile deposits. A bank with no monthly fee but high per-transaction costs may be more expensive than one with a flat $10 monthly fee if you process many transactions.
Ask whether the account includes a debit card, whether you can add authorized users (employees or partners), and what their customer service hours are. Some online banks offer lower fees but limited phone support, while traditional banks charge more but have branch locations and extended hours.
Documents checklist by business structure
| Business Structure | Required Documents | EIN Required |
|---|---|---|
| Sole Proprietorship (your name) | Photo ID, Social Security number | No, but optional |
| Sole Proprietorship (DBA) | Photo ID, Social Security number, DBA certificate | No, but optional |
| LLC | Photo ID, Articles of Organization, EIN | Yes |
| S-Corp or C-Corp | Photo ID, Articles of Incorporation, EIN, corporate resolution (some banks) | Yes |
| Partnership | Photo ID, Partnership Agreement, EIN, all partners' IDs (some banks) | Yes |
What to do if the bank denies your account
Banks occasionally deny business accounts if documents don't match, if the business registration is incomplete or expired, or if there are red flags in background checks. If this happens, ask the bank for a specific reason in writing. Common fixable issues include a name mismatch between your ID and your business registration, an expired DBA certificate, or a registration that was filed but not yet processed by the state.
If the denial is due to a documentation issue, correct it and reapply at the same bank or try a different one. If the bank cites a background check or credit history concern, you have the right to know which company conducted the check and to dispute inaccurate information. Contact the credit reporting agency directly to correct errors before applying elsewhere.
Some banks specialize in accounts for businesses with limited credit history or previous banking issues. Credit unions and community banks sometimes have more flexible approval standards than large national banks. If you're denied at your first choice, research smaller local institutions before giving up.
Frequently Asked Questions
Can I open a business account if my business isn't officially registered yet?
Most banks require proof of registration before opening an account. If you haven't filed your LLC or corporation yet, file it with your state first — this usually takes one to two weeks. For a sole proprietorship, you can open an account immediately using your personal ID and Social Security number, even without a DBA certificate, though some banks prefer to see one.
Do I need a separate business account if I'm a sole proprietor?
You are not legally required to have a separate account as a sole proprietor, but it is strongly recommended. A separate account makes tax filing easier, protects your personal assets in case of a lawsuit, and looks more professional to customers and vendors. The IRS also scrutinizes sole proprietors who mix personal and business money.
How long does it take to open a business account?
Online applications typically open within one to three business days once you submit all documents. In-person applications can open the same day if you have everything with you. The longest part is usually obtaining your EIN if you don't have one yet, which takes a few minutes online or two to four weeks by mail.
What if I don't have an EIN yet but need to open the account right away?
Many banks let you open the account using your Social Security number temporarily and add your EIN later once it arrives. Call the bank before applying to confirm they offer this option. Alternatively, obtain your EIN online from the IRS immediately — it takes just a few minutes and you can print it right away.
Can someone else open the business account on behalf of the owner?
Most banks require the business owner or an authorized representative to appear in person or verify their identity online. A spouse, partner, or employee cannot typically open the account without the owner's presence or a power of attorney document. Check with your bank about their specific policy before sending someone else to apply.
