Understanding the Account Closure Process

Closing a bank account requires a methodical approach to ensure all active payments and balances are accounted for before the account is finalized. If you have multiple accounts or linked services, it is prudent to review these connections first to prevent any unexpected issues, such as rejected direct debits or failed salary deposits, occurring after the account is closed.

Commonwealth Bank generally allows you to close accounts through their digital channels, provided the balance is zero and there are no pending transactions. In practice, preparing your account by redirecting your income and payments to a new institution before initiating the closure helps maintain your financial continuity.

How to Close Your CommBank Account

1. Close via the CommBank App or NetBank

You can initiate the closure of your transaction or savings account by messaging Ceba, our virtual assistant, through the CommBank app or NetBank. Ceba will assist in verifying your account details and processing the closure request.

2. Close by Phone

If you prefer to speak with someone, you can call CommBank's customer service:

  • Within Australia: 13 2221
  • From overseas: +61 2 9999 3283

Our team is available 24/7 to assist you with closing your account.

3. Close in Person at a Branch

Alternatively, you can visit your nearest CommBank branch to close your account. Please bring valid identification with you to complete the process.

Troubleshooting Common Issues

MFA / Login Issues

If you cannot log in to initiate the closure because your NetCode SMS is not arriving, this is often caused by mobile network congestion. A simple fix is to toggle your phone's airplane mode to force a network refresh. If the code still does not arrive, call the bank's support line to verify your registered mobile number.

Browser or App Errors

If the closure option is missing or the screen freezes, this usually happens because the application version is outdated or your browser cache is full. Try clearing your browser’s cache or updating your app through the app store. If the issue continues, using a desktop browser is a more reliable way to navigate the full settings menu.

Locked Account / ID Issues

If your account is locked due to security protocols or multiple failed login attempts, you cannot close it via self-service. The system requires identity verification to prevent unauthorized closures. The fallback action is to call the bank's support team, as they must manually verify your identity before they can process the closure for you.

Pro-Tip: Download your transaction history statements for the last 12 months before you close the account. Once the account is shut, you may lose access to digital statements, and requesting these copies from the bank later can be time-consuming and may incur additional fees.

Frequently Asked Questions

What is the CBA Osko offer, and does it affect my account closure?

Osko is not an "offer" or a promotion; it is the underlying technology (the New Payments Platform) that allows for near real-time payments between bank accounts in Australia. It has no impact on your ability to close your account. When you transfer your remaining balance to another bank before closing your CBA account, the system will use Osko (if the destination bank supports it) to move your money in real-time. If you are closing your account and need your balance moved quickly, ensure you select an immediate transfer option to leverage this service.

What happens if I forget a direct debit?

If a direct debit attempts to pull funds from an account that has been closed, the transaction will typically fail. The merchant will then be notified that the payment could not be processed, which may result in a dishonour fee from the merchant or a temporary suspension of that service. The best next step is to carefully audit your transaction history for the past 12 months before closing, and if you realize you missed a payment, contact the merchant immediately to provide your new account details.
