From 21 September 2009 a central team will deal with all new Self Assessment registrations. This means that non self-employed customers will no longer be asked to write to their local tax office when they wish to get a tax return and register for Self Assessment.
Non self-employed customers will now be able to register by ringing the Self Assessment Helpline on 0845 900 0444 or by completing a new form (SA1). Customers will need a valid National Insurance number and will be asked to provide information about what's changed, whether they call the helpline or complete the new form.
A new form SA1 has been designed to help customers who aren't self-employed to easily provide all the information HMRC needs. HMRC can then register them for Self Assessment and send out the right tax return pages.
