How long are bank cheques valid?

In the Australian banking system, cheques are generally considered valid for 15 months from the date of issue. This duration is a standard industry practice, allowing the recipient reasonable time to present the cheque for payment at their financial institution. Once this period passes, the cheque is typically regarded as "stale" and will not be accepted for deposit.

If you find an older cheque, it is important to check the date printed on the document before attempting to deposit it. Presenting an expired cheque will lead to the transaction being rejected by the clearing system, which may result in dishonour fees from your own bank. If you are the recipient of an expired cheque, you will generally need to contact the issuer to request a replacement.

Steps to deposit your cheque

If your cheque is within the validity period, follow these steps to process the deposit:

  • Check the date: Verify that the date on the cheque is within the 15-month limit. Ensure the amount in words matches the numerical amount.
  • Endorse if necessary: Sign the back of the cheque if required by the deposit method, though many modern processes do not require manual endorsement.
  • Choose your deposit method: Use the CommBank app's "Deposit a cheque" feature (if available for your account type), visit a Smart ATM, or head to a branch for manual processing.
  • Confirm receipt: Retain your deposit receipt until the funds appear in your available balance. Note that even after the cheque is accepted, the funds may take a few business days to clear.

Troubleshooting common issues

  • MFA or Login Issues: If you are unable to access your digital account to track a deposit, confirm your internet connection. If the lock persists, reset your password via the login portal or contact support to verify your credentials.
  • App or Scanner Errors: If the app fails to capture the cheque image, ensure there is high contrast and good lighting. If the system repeatedly rejects the image, use a branch-based ATM or teller service as your fallback action.
  • Locked Account/ID Access: If your account has a restriction, you may be unable to complete deposits. Call the bank's support team to confirm the status of your account and resolve any identity verification holds.

Pro-Tip: Before depositing a cheque, take a clear photograph or scan of the front and back for your own records. This acts as essential proof of the transaction in the event that a cheque goes missing during the mail or clearing process, saving you significant time if a trace needs to be initiated.

Frequently Asked Questions

Q: What should I do if my cheque has expired?
If you realize your cheque is older than 15 months, the bank system will not process it as a standard deposit. You must reach out to the person or organization that issued the cheque to explain the situation and ask them to cancel the original and issue a replacement. This is the only way to ensure the funds are properly accounted for by the issuer.

Q: Why does a deposited cheque take days to clear?
The clearing process involves the bank verifying the availability of funds from the issuing institution. This involves inter-bank communication, which is not instantaneous. Even after the cheque is accepted at an ATM or branch, the funds are held until the bank confirms the transfer is successful. Check your app's transaction history to see the "cleared" status before you plan to withdraw or spend the funds.
