I am advised by the Revenue Commissioners that a letter issued from their Galway office on the 18th January 2013 to the taxpayer requesting that he complete Form 12S tax returns for the years 2010 and 2011, in respect of his Department of Social Protection pension and any other income not previously reported to Revenue. This form will also give the taxpayer the opportunity to claim any tax credits previously unclaimed. Income Tax may be due where the taxpayer was in receipt of a DSP pension in addition to other income during the years in question. The taxpayer was contacted by Revenue as part of a project to examine those cases where there was a mismatch between Revenue's records and those of the DSP. Revenue is profiling cases where there is significant income in addition to a DSP pension and correspondence is issuing to the individual taxpayers concerned.
