I moved to Germany on the 1st of July 2016 and started working immediately. Recently I did Steuererklärung and today I got a mail from Finanzamt that I need to declare my income for the period of 0.1.01 - 30.06.2016. The problem is during that period I was living in Azerbaijan and working as a private business owner with a contract for some company and I was also a student. And I can't provide any official document regarding my income.
Any ideas what should I do in this case ?
Can I just send them a letter and say that I made x.xx money during that period ? Or what else ?
