Have you registered to file your tax return online through the HMRC website? The deadline for filing your 2009/10 tax return online is 31 January 2011, but can take up to seven working days to complete the registration process before you can start to file online.

 First you need your UTR number and your NI number or UK postcode. The HMRC website will generate a user ID which you must note down and keep it safe. You must then wait for an activation code, which is sent by post to your registered address. Once this arrives go back to the HMRC website and login with your user ID and the activation code, within 28 days of the activation code being issued. You don’t have to repeat the registration process every year.

 You can avoid this hassle by asking us to submit your tax return on your behalf.
