The Italian government expects it will get nearly €4 billion from tax dodgers who used an amnesty deal to declare money and assets abroad.
The year-long voluntary disclosure scheme resulted in nearly €60 billion being declared, according to the economy ministry.
"The (resulting) tax revenues are estimated at around €3.8 billion. With interest, the final proceeds could easily reach around €4 billion," its statement read.
During the year 130,000 voluntary declarations were made, amounting to €59.5 billion. The bulk of that, 70%, was stashed away in Switzerland.
Funds were also tucked away in Monaco, the Bahamas, Singapore and Luxembourg, the ministry said.
"Unlike previous measures, the taxpayer taking part in this scheme still has to pay the total tax and interest, it's only the penalties that have been reduced," the statement said.
The programme ended on 30 November.
The Italian government estimates that it loses more than €90 billion a year due to tax evasion, with nearly half that down to VAT not being paid.
