Known as the Imposta sul Valore Aggiunto (IVA), Italy’s Value Added Tax was introduced in 1972 primarily governed by Presidential Decree No. 633. It has incorporated EU VAT Directives into Italian VAT Laws, of which Italy is a founding member. The Italian VAT laws are backed up by case law. Also, the tax authorities produce Administrative doctrines, which state numerous VAT compliance rules. The Ministry of Finance oversees the VAT system.
