You are paying a Value Added Tax (VAT) on the registration fee because it is required by the laws and regulations of the EU and its member states. They establish that VAT must be paid on the fees in the country where the congress is held.
Possibly. Only business companies from the European Union and from these Non-European Union countries can claim back the German VAT. To recover the VAT you must provide the details of your company - name, address, VAT number or Tax ID - for all expenses invoices and submit all original documentation to your company for its processing. This includes such things as Registration, Lodging and Food invoices.
