I studied in Australia during 2005 - 2006. During this time period, I had a part time job.
I bought an Australia property during 2021 as a foreigner. Now, my accounting agency need to lodge tax return for me but find I have outstanding income tax returns from year 2004 to 2021 associated with my TFN.
How could I clear up those remain outstanding? Since I'm not able to link my TFN online for some reason, should I download the non-lodgment advice forms for each year and mail to the taxation office? Or I need to download Tax Return for individuals forms for each year, complete and mail to the taxation office?
