HM Revenue & Customs issues self-assessment warning

HM Revenue & Customs is warning those needing to complete a tax return to hit the 31 January deadline or face a £100 fine.

The government issued the reminder today as any outstanding returns must be completed this month and, if individuals are not yet registered to file their return online, they need to do so by 21 January.

Those not registered for online filing by this date may not have their return processed by the 31 January deadline because a user ID and activation code needs to be posted from the tax office.

For taxpayers that have previously used the service, the login details from last year can be reused, although reminders will also have to be sent out in the post, taking up to seven days.

31 January 2011 is also the deadline for paying any tax owed for the 2009/10 tax year.

Anyone still unfamiliar with the self-assessment process can call HM Revenue and Customs directly on 0845 9000 444 or visit the website at
