Inland Revenue online tax glitch

It seems that HM Revenue & Customs have a problem with their online system to allow the public to file their tax returns online, which is the only way you can file last year's tax return after 31 October last year. The online system is still letting taxpayers ask for any tax owed for 2007-08 to be re-paid via their new PAYE tax code for 2009-10. However this option, for tax of up to £2,000, should have ended on 30 December 2008. The HMRC have said that: "This option should be unavailable but it is presently available." Apparently it is investigating the problem "urgently".
