The tax credit legislation allows a claimant to ask us to close
down an enquiry. This will normally be because we are taking too
much time to resolve it but they can make the request as soon as
they have received the opening letter. This only applies to
enquiries and not examinations.
Closure requests are not normally made in discrepancy cases
because they are quick and straightforward challenges. If you get
such a request you should ask your manager for advice.
