Revenue says it has collected €500m from the holders of offshore accounts who had until last Thursday to declare their tax liabilities.
In its annual report published today, Revenue said 15,000 people had indicated that they would be making such settlements, although by last Thursday only 11,000 had done so.
Chairman Frank Daly said he confidently expected the total of €500m to increase further in the coming weeks. He also said this brought the total collected so far from the holders of offshore accounts to €650m.
The Revenue report showed that total gross tax receipts reached a record €43 billion last year.
There were seven convictions for serious tax evasions last year, with 38 cases currently under investigation. 16,000 audits were carried out, yielding €429m.
The Ansbacher probe yielded €42.7m, while investigations into the NIB's CMI scheme netted €50.4m. Cases related to the Flood and Moriarty tribunals yielded €25m. The report says a total of €749m has been collected from investigations into bogus non-resident accounts.
