The German tax office usually collects more taxes than needed and refunds the surplus by bank transfer in the following year, once tax returns have been filed.
I'm now working in Germany, and I'm going to return to my home EU country (Poland). I will close all things here in Germany, including my bank account. How should I apply for tax refund, then? Can I send all papers from abroad, and give my Polish bank account details? Or am I expected to go to Germany two more times, to submit the papers and then to collect the money?
I'd like to avoid the latter, because it's 16 hours by bus in one direction.
I don't want to keep German bank accoun open, because they will charge 10 Euro each month if there will be no incoming payments. It's quite typical for German banks, as fair as I know. If you work, you pay nothing, if you don't work and have no income, you have nothing to say...
