How the DGT's position has evolved
Current position
For the Personal Income Tax (IRPF) declaration, operations carried out in a currency other than the euro must be converted into this currency by applying the official exchange rate. The official rate is considered to be that published by the European Central Bank, either directly or through the Bank of Spain, in accordance with article 36 of Law 46/1998. Exchange rate differences that do not derive from an economic activity are classified as capital gains or losses.
The DGT's position remains constant throughout the analyzed sequence. No changes are observed in the definition of the official exchange rate nor in the treatment of exchange differences, which remain classified as capital gains or losses.
