I assume that the Deputy is referring to the restriction on the use of certain tax reliefs and exemptions by high income individuals. I am informed by the Revenue Commissioners that data to provide a definitive estimate of the yield from the measures outlined by the Deputy are not readily available. However, based on personal income tax returns filed for the year 2013, the latest year for which data is available, it is tentatively estimated that reducing the entry level adjusted income threshold to €100,000 and full restriction level to €200,000, with an effective tax rate of 38%, would generate an additional yield in the order of €70 million.
It should be noted that this estimate takes no account of any changes in taxpayer behaviour which might arise from the introduction of this change.
