I just received a tax form No 3517-K Regime Simplifie - Taxe sur la Valeur ajoutee et taxes assimilees for 01/01/13 to 31/12/13. I am unsure what to do with it as my Berlin-based client is supposed to declare the TVA with the German tax authorities (reverse charge). On my invoice to the Berlin company I put TVA non applicable, article 293B du Code Général des Impôts - so that they handle the TVA. Can you confirm somehow this is all correct? And can you advise on how to proceed with the 3517-K form please.
