What you need before you walk in or click apply
A business savings account requires proof that your business exists and proof of your identity. The exact documents depend on your business structure — sole proprietorship, LLC, S-corp, C-corp — and the bank you choose. Most banks want to see your business license or EIN letter, a government-issued ID, and your Social Security number or Tax ID number. Some also ask for articles of incorporation, an operating agreement, or recent business tax returns.
You will also need to decide who can sign checks and withdraw money from the account. Banks call this the "authorized signers" list. If you are the only owner, you sign alone. If you have partners or employees who need access, you name them now, and the bank will ask for their IDs and signatures too.
Have your business address ready — not a mailbox, but a physical location where the business operates or receives mail. If your business is brand new and you do not have an EIN yet, you can still open an account using your Social Security number, though some banks prefer the EIN first.
Key Takeaways
- Bring your business license or EIN letter, a government-issued ID, and your Social Security number or Tax ID to prove who you are and that your business exists.
- Different business structures (sole proprietorship, LLC, corporation) require different documents, so call the bank first and ask what they need for your type of business.
- You can open an account in person at a branch, by mail with some banks, or online through a bank's website — online is usually fastest.
- The account opens the same day or within one to three business days, and you can deposit money and start using it immediately once it is open.
- Some banks charge monthly fees for business savings accounts, while others waive fees if you keep a minimum balance or maintain direct deposit.
Three ways to open the account: in person, by mail, or online
In person at a branch is the slowest but most straightforward route if you have questions. You walk in with your documents, a banker reviews them on the spot, and the account opens that day. You can deposit an initial amount right then and get a debit card or checkbook started. This works well if your business is new and you want someone to walk you through which account type fits your needs.
By mail is an option at some regional and national banks. You send copies of your documents — usually certified or notarized — along with a signed application. The bank reviews everything and mails you confirmation and account details. This takes one to two weeks and works if you cannot visit a branch, but you cannot deposit money until the account is fully open.
Online is the fastest route at most online banks and many traditional banks. You upload photos of your documents, enter your business and personal information, and the account opens within one to three business days. You can start depositing money immediately through ACH transfer or mobile deposit. Online banks often have lower monthly fees than brick-and-mortar banks, though they do not have physical branches if you need to deposit cash.
Documents checklist by business structure
| Business Type | Documents You Need |
|---|---|
| Sole Proprietorship | Government-issued ID, Social Security number, business license or DBA certificate if you registered one |
| LLC | Government-issued ID, Social Security number or EIN, articles of incorporation or formation, operating agreement |
| S-Corp or C-Corp | Government-issued ID, Social Security number or EIN, articles of incorporation, corporate bylaws, board resolution authorizing the account |
| Partnership | Government-issued ID for each partner, Social Security numbers or EIN, partnership agreement, articles of partnership |
If you do not have all these documents yet, call the bank before you start. Many banks will open an account with a temporary EIN letter from the IRS or a business license alone, then ask for the rest within 30 days. Do not assume you need everything at once.
What happens after you open the account
Once the account is open, the bank sends you online access credentials so you can log in and check your balance, transfer money, and set up automatic transfers. You will receive a debit card in the mail within five to ten business days, and checks if you ordered them. Some banks send these immediately; others wait until the account has been open for a few days.
Your first deposit can happen the same day you open the account if you opened online or in person. You can transfer money from another account via ACH, deposit a check through mobile deposit, or — if you opened in person — hand cash to the teller. Online banks usually do not accept cash deposits, so if you need that option, choose a bank with branches.
The bank will ask you to verify your identity within a few days, usually by confirming a small deposit they make to another account you own, or by answering security questions. This is normal and takes five minutes.
Monthly fees and minimum balance requirements
Business savings accounts charge between $5 and $25 per month, though some banks charge nothing. The fee depends on your account type and the bank. Many banks waive the monthly fee if you keep a minimum balance — often $500 to $2,500 — or if you set up direct deposit from your business income.
Interest rates on business savings accounts are low, usually between 0.01% and 0.50% annually, depending on the bank and the current interest rate environment. Online banks tend to offer higher rates than traditional banks. If you are saving a large amount, compare rates across a few banks before you decide.
Some banks also charge fees for things like wire transfers, overdrafts, or closing the account early. Read the fee schedule before you open the account so you know what to expect.
Choosing between a savings account and a money market account
A business savings account is designed to hold money you do not spend every day — an emergency fund, quarterly tax payments, or money set aside for a future purchase. You can withdraw money whenever you need it, but most banks limit you to six withdrawals per month without a fee.
A money market account is similar but usually offers a higher interest rate in exchange for a higher minimum balance requirement — often $2,500 or more. If you have a large amount to save and do not need to withdraw it often, a money market account may earn you more interest. If you need to move money in and out frequently, a regular savings account is simpler.
A business checking account is different — it is designed for daily transactions and usually has no withdrawal limits. Many businesses keep both a checking account for daily expenses and a savings account for money they want to set aside.
What to do if the bank asks for more information
Some banks ask follow-up questions after you submit your application, especially if your business is new or if you listed a high expected monthly deposit amount. They might ask for a business plan, recent tax returns, or a letter explaining the source of your initial deposit. This is normal and does not mean your account will be rejected.
Respond to these requests within the timeframe the bank gives you — usually five to ten business days. If you cannot find a document, call the bank and ask if there is an alternative. For example, if you do not have a recent tax return because your business is brand new, you can often provide a business plan or a letter from a client instead.
If the bank denies your account, ask why in writing. Some banks have strict policies about certain industries or business types. If that happens, try a different bank — credit unions and online banks sometimes have different standards than large national banks.
Frequently Asked Questions
Do I need an EIN to open a business savings account?
No. You can open an account using your Social Security number if your business is a sole proprietorship. However, many banks prefer an EIN, and you will need one eventually for tax purposes. You can get an EIN for free from the IRS website in about 15 minutes.
Can I open a business account if my business is not registered yet?
Some banks will open an account for a business that is not yet officially registered, as long as you have a business license or can show proof that you are operating. Call ahead and ask — do not assume you need to wait until everything is officially filed.
How much money do I need to deposit to open the account?
Most banks require an initial deposit of $25 to $100, though some have no minimum. Check the bank's website or call before you apply. If you cannot meet the minimum, try a different bank or a credit union.
Can I add my business partner or employee to the account later?
Yes. You can add authorized signers after the account is open by going to the bank in person or through online banking, depending on the bank. The new signer will need to provide their ID and signature.
What if I already have a personal savings account at a bank — can I just convert it to a business account?
No. Personal and business accounts are separate, and banks do not convert one to the other. You will need to open a new business account. You can keep your personal account open at the same bank if you want.
