The requested information on accuracy rates is set out in the following table. HM Revenue and Customs do not use the concept of ‘tax effect errors’ in the context of national insurance contributions.
PAYE All cases accuracy Automatic process accuracy Manual process accuracy Tax effect accuracy1 2005-06 94.7 n/a 79.9 79.9 2006-07 95.1 99.8 82.1 82.1 2007-08 95.1 99.8 83.4 83.4 2008-09 96.2 99.8 83.5 83.5 1 The PAYE tax effect accuracy results relate to those cases which require a manual intervention and which have been accurately processed to within £1.
Many of the SA cases recorded as not processed accurately will be due to the coding number not being reviewed. In the majority of cases, the coding error is corrected when the SA return is submitted and the taxpayer's tax calculation will ensure the correct amount of tax has been paid.
SA All cases accuracy Automatic process accuracy1 Manual process accuracy Tax effect accuracy2 2005-06 75.3 n/a 75.3 96.5 2006-07 78.1 n/a 78.1 96.5 2007-08 80.5 n/a 80.5 97.6 2008-09 81.5 n/a 81.5 97.0 1 There is no information available for SA cases processed automatically because the assumption is that they process with near 100 per cent. accuracy. 2 The self-assessment tax effect accuracy relate to those self-assessment taxpayers whose tax bill is accurate to within £1.
