Interest Limitation under the Adopted Anti-Tax Avoidance Directive and Proportionality

Abstract:

This article scrutinizes the compatibility of the interest limitation rule the European Union (EU) legislature included in its anti-tax avoidance directive adopted on 12 July 2016 with the proportionality principle.

Under its settled case law concerning domestic interest limitation rules restricting a fundamental freedom for purposes of combating tax avoidance practices, the European Court of Justice (ECJ) holds that such measures do not comply with the principle of proportionality if they, amongst others, either do not provide the taxpayer with an opportunity to substantiate the commercial reasons for not entering into an arm’s length loan arrangement, or restrict the deductibility of more interest than an arm’s length interest.

As the rule does neither adhere to the counterevidence rule nor to the arm’s length principle, it is questionable whether its status as secondary EU law suffices for purposes of disregarding the aforementioned limitations set by the ECJ. Amongst others, the author takes the view that on the basis of ECJ case law, the interest limitation rule may be considered incompatible with the proportionality principle.
