I am advised by the Revenue Commissioners that the full year yield, estimated by reference to 2013 incomes, from extending the additional universal social charge by either 1%, 2%, 3%, 4%, 5% or 6% to all PAYE income earners income in excess of €100,000 would be of the order of €24 million, €47 million, €71 million, €95 million, €118 million and €142 million respectively. The Universal Social Charge is an individualised charge and as such, the estimate of yield is based on individual incomes of more than €100,000. The estimated yield is based on confining the extension of the new Universal Social Charge rates to the portion of income which is in excess of €100,000, that is, the increase is not applied to the portion of total income earned up to €100,000. This estimate is derived from the Revenue tax-forecasting model using actual data for the year 2010 adjusted as necessary for income and employment trends in the interim. It is, therefore, provisional and likely to be revised.
