I am advised by the Revenue Commissioners that the estimated numbers of income earners earning between €17,000 and €18,000, between €18,000 and €19,000 and between €19,000 and €20,000, by reference to the income tax year 2014, are approximately 41,000, 43,100 and 42,000 respectively (estimated numbers are rounded to the nearest hundred). These figures are estimates from the Revenue tax forecasting model using latest actual data for the year 2011, adjusted as necessary for income, self-employment and employment trends in the interim. They are provisional and may be revised. Married persons or civil partners who have elected or have been deemed to have elected for joint assessment are counted as one tax unit.
