Evasion
In the late 1990s a parliamentary inquiry under Jim Mitchell, TD, established the existence of a culture of encouraging tax evasion within Irish banks, which had allowed wealthy customers to set up non-resident (off-shore, international) bank accounts into which money was transferred, enabling the account holder to avoid paying DIRT. (Such accounts in theory should only have been set up by foreign investors, who would of course pay any tax due to their local authorities.)

Several famous Irish people have been found evading the tax, including (former) Minister for Justice Pádraig Flynn.
