The Government must plug loopholes "allowing tax exiles to sponge off society", the Irish Congress of Trade Unions has said.
Ictu's general secretary David Begg said Ireland’s wealthy elite must pay their fair share in taxes in order to fund public services.
Mr Begg said: “Politics in Ireland is being undermined by this new breed of super rich people who demand tax breaks where ever they go but who don’t want to pay tax anywhere.”
Ictu said current social partnership talks have the potential to create a more equitable tax system if every member of society contributes.
Mr Begg added: “The development of a sustainable modern economy cannot be left to the devices of a privileged wealthy elite whose only objective is to make themselves even richer.
"The tax base must be broadened by eliminating tax breaks and tax exemptions that are regressive and disproportionately benefit the rich or allow high earners to minimise their tax bill.“
Ictu, which represents 830,000 workers across the island, today launched its document Rewarding Productivity and Promoting Social Equity - Tax Reform in the Context of a New National Agreement.
The 21-page document formed part of Ictu's submission to the new Commission on Taxation.
