Understand the scope

Definition and points to distinguish

Mechanisms relating in particular to interest or hybrid mismatches have their own conditions. They should not be reduced to a percentage applied without examining the group and the transaction.

What this changes in practice

The ATAD Directives provide a framework for European measures to combat tax avoidance, implemented in national laws. They do not constitute a single rule that applies identically to every transaction. The relevant mechanism must be identified, such as an interest limitation or an anti-hybrid measure, and then its transposition and scope must be examined. The analysis is based on the group’s actual flows and structures.

A scenario to help you understand

Educational example

A group finances a company through debt. It examines the deductibility of interest and the rules applicable to the period, without concluding that payment alone is sufficient to justify its full deduction.

Pourquoi ATAD peut-elle affecter un financement ordinaire de groupe ?

Les dispositifs anti-évitement peuvent limiter certains traitements même lorsqu’un contrat existe et que les comptes enregistrent l’opération. L’analyse dépend notamment de la structure, des charges financières et des situations transfrontières. Identifiez les règles nationales applicables et leurs interactions. Il ne suffit pas de vérifier un seul article sans considérer le fonctionnement économique de l’ensemble de l’opération.
