The starting point here will always be the accounts actually drawn up by the company. The questions to be asked will then be:
It will very often be possible to take a more sanguine view of
the likely economic life or value of an intangible asset than that
reflected in a company’s accounts. But these provisions are
not intended to open up a whole new area of contention over
companies’ tax liabilities, concerned with what is the most
acceptable accounting practice. In particular, where it turns out
that the company has properly considered the matter and come to a
tenable conclusion as to the most appropriate policy and estimation
technique, then the financial statements should not be challenged
on the basis that another policy or estimation technique could have
been used.
Enquires into the relevant accounting judgements should
therefore be focused on unusual circumstances where there are clear
grounds for concern, and where both the tax potentially at stake
and the likelihood of an adjustment justify the decision. In such
cases some preliminary fact finding will be essential to try to
establish at an early stage whether the accounting treatment is
sufficiently extreme to justify continuation of the enquiry.
See CIRD30130 for examples of relevant factors in choosing cases for enquiry and CIRD30140 regarding the need to involve Revenue accountants. The article entitled ‘Revenue Accountants’ in Tax Bulletin No 58 contains more general comment on the circumstances in which a company’s accounting policies may be challenged.
