I've searched the forum for this topic and could not find it. It may exist somewhere on TT, but if it does it's buried somewhere.
I previously lived in Berlin (left in January 2010) as a freelance English teacher. I paid taxes in Berlin as a freelancer and I have a tax number (Steuernummer) from the Finanzamt in Berlin.
I returned to the U.S. in January 2010 for a year before I returned to Germany. I am now in Leipzig and have an Arbeitsvertrag with a German company. I just submitted my pile of paperwork to the Aüslanderbehörde and should hear back about my new residence permit in the next 2-3 weeks, however I'm confused about the Steuernummer.
I know that I have to get a Lohnsteuerkarte after I receive the residence permit, but do I need to also go to the Finanzamt and get a new tax ID number or will my old one still work? If I do need a new one, what happens to my old Steuernummer?
Any help on this subject would be greatly appreciated.
