Hi @rinemaniti,

Are you trying to link your myGov account with ATO Online services?

If you don’t have information to answer questions specific to you, you can use a linking code.

We have information on how to link your myGov account to the ATO on our site.

Let us know if you require further help or if I misunderstood the question.
