myGov help - Link Child Support to myGov using a linking code

Instructions on how to link Child Support to your myGov account if you have a linking code.

To start you’ll need a myGov account. If you don’t have one, you can go to the myGov website to create one.

If you’re not an existing Child Support customer, you won’t be able to link to your myGov account. You can go to the Services Australia website to find out more about applying for a Child support assessment.

To link your Child Support online account to your myGov account, you’ll need your linking code and your Child Support Reference Number (CSRN).

A linking code is a single use code we give you to link Child Support to your myGov account. You can get a linking code by calling Child Support.

Make sure you have this information ready before you begin.
