I have been informed by the Revenue Commissioners that the information furnished on tax returns generally does not require the yield from a particular sector or sub-sector of trade to be identified. In these circumstances, the amount of tax revenues collected under all taxation headings in respect of the horse-racing and breeding sector cannot be readily identified from the overall yield from taxation. Accordingly, the specific information required by the Deputy is not readily available and could not be obtained without conducting a protracted examination of the Revenue Commissioners' records.
