HM Revenue & Customs (HMRC) is issuing a call to all Self Assessment newcomers preparing to send a tax return online for the first time - make sure you register for HMRC’s online services well in advance, so you have plenty of time to file your return.

The October 31 deadline for paper returns for the 2011-12 tax year (April 6, 2011 to April 5, 2012) has now passed, so any outstanding returns must be sent online by January 31, 2013 - just a few weeks away.

It is important to register for HMRC’s online service as early as possible because it can take up to seven working days to complete the process, as an Activation Code has to be posted to you.

To register visit hmrc.gov.uk/signup and follow the instructions. You will immediately get a User ID and, once you have received the Activation Code in the post, you can activate your account. You can then complete your tax return online.

As well as your online tax return, any tax you owe for 2011-12 must also reach HMRC by January 31, 2013.

For help and advice on completing a return, visit hmrc.gov.uk/sa or call the Self Assessment helpline on 0845 9000 444.
