The file should normally carry a general BU date (
IHTM32032) for between 30 and 60 days.
When choosing a review date, you should judge each case on
its merits. The time allowed to respond to an initial informal
request for information whether in a new enquiry or an older
working case, should be a minimum of 30 days. But you should use a
BU date of up to 60 if there are special circumstances that suggest
a longer time would be appropriate.
The following factors may be relevant and need to be
considered when setting a BU date
If the taxpayers fail to provide the information by the BU date
you should set future BU dates in accordance with the procedures
for dealing with delay by taxpayers (
IHTM32121).
If the only outstanding points are matters dealt with by the
VOA (
IHTM23000), SV or Heritage you may in
some circumstances consider a longer BU period of, say, between 3
to 6 months. You should however consult your manager if you are in
any doubt about this or before you set a BU date for any period in
excess of six months.
