Advisers do not use scripts, but do have access to online support and advice tools to help them in answering customer’s questions. To put these online tools into a format suitable for publication would incur disproportionate cost. However the tax credit manual and the tax credit technical manual are already publicly available on the HMRC website at:
http://www.hmrc.gov.uk/manuals/ntcmanual/index.html
and
http://www.hmrc.gov.uk/manuals/tctmanual/index.html
respectively.
HMRC estimate that around 21 per cent. of the calls made to the tax credit helpline during the November 2007 were made from a mobile phone.
