Value Added Tax (VAT) in Switzerland was introduced in 1995. Switzerland is not part of the European Union, however it operates with a very similar system of VAT. In Switzerland, the VAT is also known as Mehrwertsteuer (MWST), Taxe sur la valeur ajoutée (TVA) or Imposta sul valore aggiunto (IVA).
The official administrative languages in Switzerland are German, French and Italian depending on which Canton/County your are in. Administrative correspondence must be in the German language.
