Child Support online account help - Update bank details

Instructions on how to update your bank details using your Child Support online account.

All payments made through Child Support will be sent to your nominated bank account.

Before you start, make sure you have your new details including the following:

  • Account name
  • BSB number
  • Account number.

We’re redesigning Child Support online with an updated look and feel. You can no longer edit your bank details using your current Child Support online account. To edit your bank details, use the new My profile summary service, which can be accessed from the new Child Support homepage through myGov.

You can still access your current Child Support online account for other services.

Step 1: get started

Sign in to myGov or the myGov app and select Child Support.

From your Child Support homepage, select My profile summary.

The My profile summary page shows your current bank account details. To protect your personal information, we’ll only show the last 4 digits of your account number. If you don’t recognise these details, contact us.

Select Edit bank details. If you haven’t provided any bank details, select Add bank details.

Step 2: update bank details

Enter your new accounts details, including the following:

  • Account name
  • BSB
  • Account number.

Select Next.

Step 3: review and submit

We’ll give you a summary of the details you’ve provided.

Check the Bank details to make sure they’re correct.

Select either:

  • Edit bank details if you need to make any changes
  • Cancel if you don’t want to continue.

If all the details are correct, read the declaration. If you understand and agree with the declaration, select I have read, understood and accept the declaration. Then select Submit.

Step 4: receipt

We’ll give you a receipt when you submit your update. Make note of the Receipt ID for your records.

The information you’ve updated may not appear in your online account straight away.

Select any of the following:

  • Save receipt to keep a PDF copy of your receipt
  • Back to My profile summary to view and edit other details
  • Return Home to go back to your online account homepage.

Step 5: sign out

From your homepage you can complete other transactions or select Return to myGov to go back to your myGov account.

For your privacy and security, sign out when you have finished using your myGov account.
