It is assumed that the measure outlined by the Deputy is in addition to the surcharge of 3% on non-PAYE income in excess of €100,000.
I am advised by Revenue that the estimated first and full year yield to the Exchequer from a change of this nature is €240m and €310m respectively.
It is not possible, using existing data, to accurately estimate the yield that would arise from implementing this change for the final quarter of 2022 only. On a technical basis, assuming the surcharge would only apply to those taxpayers whose annual income exceeds €140,000 and that the surcharge would only apply to income arising in the period specified, then the yield may be tentatively considered to be in the region of €60m.
However, I am advised by Revenue that it would not be possible to implement such a proposal with effect from 27 September 2022.
