When calculating the penalty you think is appropriate you
should reduce the maximum 100% penalty to take into account the
following abatements
| Type of abatement | Purpose | Reduction allowed |
| Disclosure ( IHTM36181) | To take account of any disclosure and its completeness | Up to 20% (or up to 30% in exceptional circumstances ( IHTM36183)) |
| Co-operation ( IHTM36191) | To recognise the taxpayer’s co-operation with our enquiries and the extent to which the necessary information was made quickly available. | Up to 40% |
| Gravity ( IHTM36201) | To take account of the gravity of the offence | Up to 40% |
The above percentages are shown in leaflet IHT 13, together
with a brief description. You should always be prepared to explain
how you have arrived at what you regard as the appropriate
abatements. You will normally be able to point out that your
suggested figure represents a substantial reduction of the maximum
penalties for which formal action could be taken.
The deduction you allow under each heading should be based on
a separate and realistic appraisal of that particular abatement
factor alone. Any links between the abatement factors should be
ignored. This means that a taxpayer whose offences are serious but
who makes a full and spontaneous disclosure followed by maximum
co-operation will qualify for full reductions for disclosure and
co-operation with an appropriately high loading for gravity.
Another taxpayer, having offended less seriously, may in the
absence of disclosure and co-operation end up with a higher
percentage loading.
The objective is to encourage and reward immediate disclosure
and willing co-operation leading to a speedy settlement, while at
the same time recognising the degree of seriousness of the offence.
This means that a taxpayer who has made a genuine attempt to put
things right as quickly as possible will get a greater abatement
than someone whose admissions have been less than frank and
co-operation has been reluctant or withheld. Any doubt concerning
the level of abatement for disclosure and co-operation should be
resolved by reference to this objective.
