A few years ago, I moved out of Australia and cancelled my Australian phone number. What a mistake before backing up everything and updating all necessary companies before cancelling or getting a new number!
I also updated my preferences as 'Online Notifications' at ATO when I was in Australia.
I finally am able to get another Australian phone number while I'm overseas, however, myGov app is gone with the old phone, and cannot login to my online services due to a generated code by myGov app.
I could create a new myGovId account, and tried to link ATO Online to my new myGovId, however, ATO services requires me to provide a number from one of Australian offices (ATO NOA, Centrelink payment, Medicare, etc.. )Another number issue!...
As I selected to receive ATO communication online, all letters goes into myGov inbox which I have no access.
I tried to contact ATO Helpdesk and they connected me after a long wait over the phone, she asked me similar questions, and numbers again! I have not received any payment from Centrelink, or Medicare letters during the time when I was overseas, thus I have no letters yet to provide a number.
ATO Helpdesk lady also recommended me to apply for a new TFN, and I would get the same number by creating a new account. however, I received a response immediately when I tried to apply for a new TFN, stating that I already have a TFN and account.
I have/know all my passwords for myGov account, and newly created myGovId account. However, I cannot login or connect ATO online services due to not accessing to my online letters.
I checked the myGov Helpdesk number for overseas, however, that number does not work from overseas!
+61 1300 1MYGOV (1300 169 468)
I don't know how to access my ATO account, or how to link it!
