Due to Italian legislation the established bodies are required to list in their annual tax return their foreign funds, assets and related earnings as they exceed €10000.
[1][2][3] The 2001 Scudo Fiscale brought to light that 78 billion euros were held by Italians in Switzerland.
The relevant law was named Imposta straordinaria sul rimpatrio di attivita` finanziarie e patrimoniali detenute fuori del territorio dello Stato ("Extraordinary tax on the repatriation of foreign financial and patrimonial assets ").
The list was called "Dichiarazione riservata" (in English Private declaration) and was similar to an annual tax return.
On the other hand, the payer obtains a document which confirms a payment and guarantees dropping of more investigations or penalties.
