You cannot open a bank account by depositing a check as your first deposit, but you can deposit one immediately after opening

Banks require an initial deposit to open an account, and that deposit must be made in cash, by transfer from another bank account, or sometimes by wire. A check does not count as a valid opening deposit because the bank cannot verify the funds exist until the check clears — which takes several days. Once your account is open and active, you can deposit checks normally.

The reason for this rule is straightforward: a check is a promise to pay, not actual money. The bank opening your account needs to confirm that real funds are sitting in your new account before they consider it officially open. If you showed up with a check and the check bounced after the account was created, the bank would have an empty account on its hands with no way to recover the opening deposit.

Key Takeaways

  • Your opening deposit must be cash, a transfer from another bank account, or a wire transfer — not a check.
  • The opening deposit amount varies by bank and account type, ranging from zero dollars at some online banks to $100 or more at traditional banks.
  • Once your account is open, you can deposit checks through mobile deposit, at an ATM, or by handing them to a teller.
  • If you do not have cash or access to another account, a wire transfer from someone else's account can serve as your opening deposit.

What counts as a valid opening deposit

Banks accept three types of opening deposits. Cash is the simplest — you walk in with bills and coins, hand them over, and the deposit is immediate. Transfer from another bank account means moving money from a checking or savings account you already have at a different bank; this takes one to three business days to arrive but is treated as a confirmed deposit. Wire transfer means having someone send you money electronically from their bank account to your new account; this also takes one to three business days and requires you to provide the sending bank with your new account number and routing number.

Some online banks have zero opening deposit requirements, meaning you can open an account with no money at all. In that case, you can deposit a check on your first day. But most traditional banks and credit unions require a minimum opening deposit, typically between $25 and $100, though some require more.

How to deposit a check once your account is open

After your account is active, you have three ways to deposit a check. Mobile deposit means photographing the front and back of the check with your phone using your bank's app, then submitting it electronically; this is the fastest method and usually takes one to two business days to clear.

Whichever method you use, the check will not be available as spendable money immediately. Banks place a hold on deposited checks, meaning the funds are reserved but not yet in your account. For checks under $200, the hold is usually one business day. For larger checks or checks from out-of-state banks, the hold can be five to ten business days. During the hold period, you cannot withdraw that money, even though it shows as deposited in your account.

If you do not have cash or another account to open with

If you have no cash and no existing bank account, ask someone you trust — a family member, friend, or employer — to wire money to your new account as your opening deposit. You will need to provide them with your new account number and your bank's routing number, which the bank will give you when you open the account. The wire will arrive within one to three business days and counts as a valid opening deposit.

Another option is to ask if the bank will accept a check as your opening deposit if a bank employee is present. Some banks make exceptions for customers who are opening accounts in person at a branch, especially if you can show ID and the check is from a local source. This is not may provide, but it is worth asking — the worst they can say is no.

Why banks have this rule

The opening deposit rule exists because banks need to know your account has real money in it before they activate it. If someone opened an account with a bad check and the account was already active, they could start writing their own checks against that account before the original check bounced. This would create a cascade of problems for the bank and other customers.

Additionally, banks are required by federal law to verify customer identity and source of funds when opening accounts. An opening deposit in cash or from a verified source helps them complete this verification. A check from an unknown source does not provide that verification until it clears.

Minimum opening deposits by account type

The amount you need to open an account varies. Most checking accounts require $25 to $100. Savings accounts often have lower minimums, sometimes zero. Money market accounts typically require $2,500 or more. Online banks frequently have no minimum at all. Credit unions vary widely depending on membership requirements and the specific account.

If you are opening an account with a very small amount of cash and the bank's minimum is higher, ask whether they will waive the minimum or let you deposit the difference by check once the account is open. Some banks will do this, especially if you are opening the account in person and can explain your situation.

What happens if your opening deposit check bounces

If you somehow manage to deposit a check as your opening deposit and it later bounces, the bank will close your account and may charge you a returned-deposit fee, typically $10 to $25. You will also be responsible for any overdraft fees if you spent money against that check before it bounced. This is why banks do not accept checks as opening deposits in the first place.

If you are in this situation, contact the bank immediately and explain what happened. Some banks will work with you to resolve it, especially if you can deposit the correct amount in cash or by transfer within a few days. Others will simply close the account and report it to ChexSystems, a banking history database that other banks check when you try to open new accounts.

Frequently Asked Questions

Can I open an account online with a check as my opening deposit?

No. Online banks require either a transfer from another account or no deposit at all. You cannot submit a check image as your opening deposit because the bank cannot verify the funds before activating your account. Once your account is open, you can deposit checks through mobile deposit.

What if the check is from my employer?

An employer check does not change the rule. Banks still cannot use it as an opening deposit because it is not may provide funds until it clears. However, if you are opening the account in person at a branch, some banks may make an exception for a paycheck if you can show your employee ID and the check is recent.

How long does a check take to clear after I deposit it?

Most checks clear within one to three business days. Larger checks, checks from out-of-state banks, or checks from banks the receiving bank does not have a relationship with can take five to ten business days. During this time, the money is not available for withdrawal, even though it shows in your account balance.

Can I deposit a check on the same day I open my account?

Yes, as long as you open the account first with cash, a transfer, or a wire. Once your account is active, you can deposit a check immediately — either in person at a branch, through an ATM, or using mobile deposit. The check will then go through the standard clearing process.

What if my bank says they will not accept my opening deposit?

If a bank refuses your opening deposit, they will not open the account. This usually happens if the deposit is a check or if you cannot verify your identity. Ask what forms of opening deposit they accept and whether they have a minimum amount. If you cannot meet their requirements, try a different bank or an online bank with no opening deposit requirement.
