Closing a credit card is a routine part of managing your personal finances, often done when your spending habits change or you no longer require a specific line of credit. Before the account can be closed, Commonwealth Bank requires that the card balance be brought to zero, which means all transactions, interest charges, and annual fees must be fully settled.
Because the bank processes closures through a secure verification system, the timing of your request can depend on whether there are pending transactions still being cleared by merchants. Taking the time to prepare your account before initiating the request helps prevent delays in the cancellation process.

Troubleshooting Common Issues
MFA and Login Issues
Cause: You might not receive the NetCode SMS verification required to confirm your identity during the closure process if your registered mobile number is outdated.
Simple Fix: Update your contact details in NetBank before starting the process, or ensure you have a strong mobile signal to receive the code.
Fallback Action: Contact the bank’s support line to verify your identity verbally and proceed with the closure over the phone.
Browser or App Errors
Cause: Outdated versions of the CommBank app or a full browser cache can often lead to pages freezing when you try to submit a closure request.
Simple Fix: Force close the app and check for updates, or clear your browser cache before trying to log in again.
Fallback Action: Switch to a desktop computer and use NetBank, or visit a branch where a staff member can assist you.
Locked Account or Access Issues
Cause: Repeated attempts to log in with incorrect credentials or security codes will trigger a temporary lockout for your safety.
Simple Fix: Use the 'Forgot password' tool to securely reset your credentials using your card details.
Fallback Action: If the account remains locked, you will need to call the bank to have the security restriction manually removed.
Pro-Tip: Before closing your account, download or print your last 6–12 months of statements. Once the account is closed, you may lose access to your online transaction history, and having these records is useful for your personal tax or budgeting references.
Frequently Asked Questions
Why was my request to close the card rejected?
You might have submitted a closure request, only to receive a notification that it could not be processed. This often happens because there is still a small outstanding balance—perhaps a few dollars in interest or a pending merchant transaction that just cleared. The banking system requires a perfectly clear $0 balance to finalize the closure. Your next step is to log into NetBank, check the 'Pending' section for any final charges, and pay off any remaining amount before attempting to close the account again.
What happens to my recurring subscriptions if I close the card?
Imagine you have your streaming services and gym membership linked to your credit card. When the account closes, the bank stops all transaction processing for that card number. Any merchants attempting to charge that card will receive a 'declined' response, which might lead to service interruptions or late fees from those companies. A limitation is that the bank cannot notify these merchants for you. You must contact every service provider that has your card details and provide a new payment method before you close the credit card account.
