I moved to Bavaria, Germany, in late march 2021 from Australia. I have paid income tax for that year in Australia.
I recieved letters from the Bavarian state government asking for income tax information for that year, and I was told by friends that their tax rate was impacted by this. Germany has a double taxation agreement with Australia, so I am not sure why I am being approached. This happened after I filed my first tax declaration a few weeks ago here in Germany.
Note that due to convoluted 2 factor authenticaiton I can no longer get access to my Australian tax data which is stored online, despite conversations with the Australian Tax Office. I also am not a resident for tax purposes in Australia and have no assets other than a savings account there.
Do I need to find a way to respond with all my income tax documents and risk them taxing me twice, aren't they missing the double taxation agreement with the other country?
Attached are the documents sent by the Bavarian government for reference.
