- Only a Swiss-based fiscal representative can submit your Swiss VAT declaration; this is mandatory for foreign companies.
- VAT declarations are generally filed quarterly, with a 60-day deadline after each quarter ends.
- The process is fully online via the Swiss Federal Tax Administration (AFC) portal.
- Late submissions incur 4% interest and errors can lead to penalties.
- A valid Swiss VAT number and official registration with the AFC are required before declaring VAT.
