TPG2022 Chapter III paragraph 3.45

« | »

It would not be appropriate to give systematic preference to one approach over the other because, depending on the circumstances of the case, there could be value in either the “additive” or the “deductive” approach, or in a combination of both. The “additive” and “deductive” approaches are often not used exclusively. In a typical “deductive” approach, in addition to searching public databases it is common to include third parties, for instance known competitors (or third parties that are known to carry out transactions potentially comparable to those of the taxpayer), which may otherwise not be found following a purely deductive approach, e.g. because they are classified under a different industry code. In such cases, the “additive” approach operates as a tool to refine a search that is based on a “deductive” approach.
