Mr. Boswell: To ask the Chancellor of the Exchequer if he will make a statement on the accuracy on Inland Revenue tax computationsafter self-assessment by taxpayers. [17230]Dawn Primarolo: [holding answer 25 November 1997]: The vast majority of around 3 million calculations so far issued are correct.However, errors can occur if the taxpayer provides incorrect information, or information is not properly keyed into Inland Revenuesystems by staff. Inland Revenue offices have quality assurance processes in place to minimise the latter form of error, and thesewill be enhanced as experience is gained of the new system. Where an error is pointed out to the Inland Revenue, or where one ispicked up during the inquiry process, it will be corrected.
