TMA70/S31(1)(d) grants the right of appeal against any
assessment to tax which is not a self assessment. The only
assessments that can be made under ITSA are discovery assessments.
If an appeal is made against a HMRC assessment the appellant
may apply under TMA70/S55(1)(b) to postpone payment of all or part
of the tax etc charged.
The normal procedures for dealing with appeals and
postponement applications apply (see AH0100 and subsequent
paragraphs).
A taxpayer can object to the discovery assessment on the
grounds that no assessment should have been made because neither of
the two necessary conditions, set out in the discovery legislation,
were satisfied. These are
An objection to a discovery assessment on the grounds that one
of the two conditions is not satisfied can only be by way of an
appeal.
An appeal can also be made against the quantum etc of a
discovery assessment.
If the discovery assessment is a further assessment the same
rights of appeal apply as with main assessments, but the making of
the further assessment does not give any further right of appeal
against the associated main assessment which has become final and
conclusive (see Ingle v Farrand, 11TC446).
