 Investigators have seized a total of 892 million euros (�620m) |
Irish tax authorities have reported collecting more than 111 million euros (�77m) in unpaid tax from offshore Jersey accounts. Investigators have been pursuing people who evade tax with bank accounts in Jersey and the Isle of Man.
Officers found 254 account holders at the Jersey branch of the Bank of Ireland who owe taxes in Ireland.
The investigation is part of a wider investigation of so-called British tax havens.
And officers believe seizures in Jersey could yield much more.
Frank Daly, chairman of the Irish Revenue Commissioners, said: "This, I think, is only the start of this investigation.
"Our view would be that there is more out there."
Investigators have seized a total of 892 million euros (�620m), Mr Daly told the Irish parliament's Public Accounts Committee.
Tax evasion in Ireland has reportedly become endemic among its elite business and political figures and ordinary residents who falsely claim they have foreign addresses to avoid paying tax on Irish accounts.
Last month Revenue Commissioners published the names of 400 people in its biggest list of tax defaulters yet.
Among those named was Fianna Fail TD (Irish MP) Michael Collins, who paid a settlement of 130,602 euros (�90,390).
