The annual cost of 28 tax reliefs is €8.38 billion, according to figures released today to the Labour Party.
The party's Finance spokesperson, Joan Burton, said the Revenue Commissioners had also told her they are unable to give any figures for the cost of another 33 allowances, including exemptions for stallion fees, donations to third level institutions, and income from foreign trusts.
Deputy Bruton said these generous tax allowances are generally options only wealthy people can avail of.
