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?
