After the notice of a determination under FA03/SCH14/PARA2 has
been served the determination cannot be altered except in
accordance with FA03/SCH14/PARA3 or on appeal.
In a case where, after the determination has been made under
FA03/SCH14/PARA2, an officer of the Board discovers that the amount
which was taken into account as the relevant amount of tax is or
has become excessive, the determination should be revised so that
the penalty is set at the amount which is correct; and, where more
than the correct amount has already been paid, the appropriate
amount shall be repaid.
If an officer of the Board discovers that the amount of a
penalty determined under FA03/SCH14/PARA2 is or has become
insufficient the officer may make a determination in a further
amount. Consequently the penalty would then be set at the amount
which, in their opinion, is correct or appropriate.
