I am advised by the Revenue Commissioners that due to an error on Revenue's part, the taxpayers concerned paid an excessive amount of tax for the years in question. Revenue's records reflected that the taxpayers were in receipt of a payment from the Department of Social Protection when in fact they were not. On 3 April 2014 the taxpayers requested a full review of their tax affairs. A refund amounting to €9,504.82 issued on 7 May 2014 for the years 2010 to 2013. Revenue has now carried out a review of the earlier years and advise that additional refunds are due which will issue shortly. They will contact the taxpayers to clarify the situation and apologise for the inconvenience caused.
