[holding answer 12 May 2009]: In April 2009 HM Revenue and Customs (HMRC) identified an accounting issue which affected some customers who had submitted 2008-09 Self Assessment Tax Returns (paper as well as online). As a consequence, from 20 April to 2 May 2009 HMRC suspended processing all Tax Returns onto their back-end systems to ensure customers did not receive incorrect calculations and statements. The issue was rectified on 1 May 2009 and HMRC resumed processing on 2 May 2009. Any resulting repayments have been made in accordance with normal processes.During this period customers were still able to file their online and paper Tax Returns. Between 20 April 2009 and 2 May 2009 the Self Assessment Online Service was fully available apart for a period of 10 hours of planned downtime on 29 April 2009.
