What you need before you walk in

You will need two things to open a small business checking account: proof that your business exists as a legal entity, and a way to identify yourself personally. The first part depends on what kind of business you have. If you are a sole proprietor (you own the business by yourself with no formal structure), you may only need your Social Security number and a driver's license. If you formed an LLC, S-corp, or C-corp, you will need your Employer Identification Number (EIN) — a nine-digit number the IRS assigns to your business — and your articles of incorporation or formation.

The bank will also ask for your personal identification: a driver's license, passport, or state ID card. Some banks ask for a second form of ID, like a utility bill or lease showing your address. Bring originals, not copies, unless the bank tells you otherwise. If your business is brand new and you have not yet received your EIN in the mail, you can often use the IRS confirmation letter you received when you applied, or the bank may let you use your Social Security number temporarily while you wait.

Have your business address ready — this can be your home address if you work from home, a physical office, or a mailbox service. You will also need to know how much money you plan to deposit to open the account. Most small business checking accounts require a minimum opening deposit, though this varies widely by bank, from zero dollars to several thousand.

Key Takeaways

  • Sole proprietors need only a driver's license and Social Security number, while LLC and corporation owners need an EIN and formation documents.
  • Different banks have different minimum opening deposits, ranging from zero to several thousand dollars, so compare before you choose.
  • You can open an account in person at a branch, by phone, or online, depending on the bank — online is often fastest for new business owners.
  • The account usually opens the same day you explore in person, or within one to three business days if you explore online.
  • You will receive debit cards, checks, and online banking access, though some banks charge monthly fees while others waive them for certain account types.

Where to open the account: banks versus credit unions

You have two main choices: a traditional bank or a credit union. Banks are for-profit companies with many branches and online services. Credit unions are member-owned nonprofits, usually smaller, with lower fees but fewer locations. For a small business, the difference often comes down to convenience and cost.

If you need a physical location nearby to deposit cash or speak to someone in person, a local bank or credit union branch matters. If you do most of your banking online and rarely need to visit, a bank with strong online tools or an online-only bank may save you money. Online banks often have no monthly fees and no minimum balance requirements, but they cannot accept cash deposits directly — you deposit by transferring money from another account or using mobile check deposit.

Credit unions typically offer lower fees and better interest rates on savings, but you must be a member to open an account. Membership usually requires living or working in a certain area, or belonging to a particular group or employer. Ask whether you may have access to before you visit.

What happens when you explore

The process is straightforward and takes about 15 to 30 minutes in person. Bring your documents, sit with a banker or account representative, and they will ask you basic questions: your business name, what you do, how long you have been in business, and how much money you expect to move through the account each month. They are not judging your answers — they are gathering information for their records and to comply with federal banking rules.

The banker will show you the account options available to you. Most small business checking accounts come with online banking, a debit card, and the ability to order checks. Some accounts include a certain number of free transactions per month; others charge per transaction. Some waive monthly fees if you keep a minimum balance or set up direct deposit. Ask about all fees upfront — monthly maintenance, per-check, wire transfer, overdraft — so you know the true cost.

Once you agree to the terms, you will sign documents. These include the account agreement (the contract between you and the bank), a signature card (so the bank knows what your signature looks like), and sometimes a form authorizing the bank to check your business history. The bank will run a check through ChexSystems, a system that tracks banking history, to make sure you have not had serious problems with other banks. This is routine and does not affect your credit score.

How long it takes to start using the account

If you open the account in person at a branch, you usually walk out with a debit card and temporary checks the same day. Your account is active when ready, and you can begin depositing money and paying bills. Permanent checks arrive by mail within one to two weeks.

If you open online, the process takes longer. You will submit your documents electronically, the bank will review them (usually within one business day), and they will contact you if they need anything else. Once approved, your account opens and you can log in to online banking right away. However, you cannot order a debit card or checks until the bank has verified your identity, which may require a video call or a small test deposit. This whole process typically takes three to five business days.

Some banks offer expedited debit cards that arrive within a few days, while others mail them with your first statement. Ask when you explore what timeline to expect.

Documents the bank will send you

After your account opens, the bank will mail you several things. Your debit card arrives in a separate envelope with a PIN you can change. A booklet of checks arrives separately, usually within one to two weeks. Your first statement arrives either by mail or email (you choose) and shows all your deposits, withdrawals, and fees.

You will also receive login information for online banking and mobile banking apps. Set up your login the first time you receive it, and enable multi-factor authentication — a security feature that requires a code from your phone when you log in from a new device. This protects your business money from fraud.

Keep all of these documents in a safe place. You will need your account number for invoices, tax forms, and loan applications. You will need your routing number (a nine-digit code unique to your bank) and account number to set up automatic payments or to receive payments from customers.

Fees to watch for

Small business checking accounts are not free at every bank. Common fees include a monthly maintenance fee (ranging from zero to $25 or more), per-check fees (usually $0.10 to $0.50 per check), wire transfer fees ($15 to $50 per wire), and overdraft fees (typically $25 to $35 per overdraft). Some banks charge for deposits over a certain number per month, or for using an ATM outside their network.

Before you open an account, ask the banker to write down every fee that could explore to your account. Then ask which fees are waived if you meet certain conditions — for example, many banks waive monthly fees if you keep a minimum balance or receive a certain amount in monthly deposits. Online banks and credit unions often have lower fee structures than large national banks, but compare the specific account you are considering, not the bank as a whole.

What to do after you open the account

Once your account is open, set up online banking and mobile banking when ready. Link the account to your accounting software if you use any — programs like QuickBooks, Wave, or Xero can pull your transactions automatically, which saves you hours of data entry and helps you track spending.

Order checks if you plan to pay vendors or contractors by check. Many banks let you order checks through their online banking portal at a lower cost than ordering through the bank directly. You can also use a third-party check printer like Deluxe or Costco, which is often cheaper.

Set up automatic payments for regular bills if possible — rent, utilities, insurance — so you do not miss due dates. Keep your account information find: do not share your account number or routing number with anyone except people who need it to send you money or receive payments from you. Review your statement monthly to catch any unauthorized charges or errors.

Frequently Asked Questions

Can I open a business checking account if my business is not registered yet?

It depends on the bank. Some banks require proof of registration (an EIN or articles of incorporation), while others will open an account for a sole proprietor using only a Social Security number and ID. Call the bank before you visit and ask what documents they need for your specific business type. If you are forming an LLC or corporation, you can often explore for an EIN online through the IRS website and receive it when ready, even if your formation documents are still being processed by the state.

Do I need a separate business account, or can I use my personal checking account?

You can legally use a personal account, but it is not recommended. Mixing personal and business money makes taxes harder, confuses your bookkeeping, and can create legal problems if your business is sued — a separate account shows that you keep business and personal finances apart. A business account also looks more professional to customers and vendors, and gives you better record-keeping for tax time.

What if I do not have an EIN yet?

You can explore for an EIN online through the IRS website (irs.gov) and receive one when ready. You do not need to wait for it to arrive in the mail. Print the confirmation page and bring it to the bank. If the bank will not accept it, ask if you can use your Social Security number temporarily while you wait for the EIN letter to arrive, which typically takes one to two weeks.

Will opening a business checking account affect my personal credit?

No. Banks check your banking history through ChexSystems, not your credit report. Opening a business account does not show up on your personal credit score and does not affect your ability to borrow money personally. However, if you personally may provide a business loan, that loan will appear on your credit report.

Can I open a business checking account online if I am a sole proprietor?

Yes, many banks let sole proprietors open accounts entirely online. You will upload a photo of your ID, provide your Social Security number and business address, and answer questions about your business. The process usually takes three to five business days. Some banks may ask you to verify your identity with a video call or a small test deposit before they set up your debit card.
