Combating abusive EU corporate income tax practices

Abstract

This thesis examines the concept of EU corporate tax abuse in light of the tensions between the protection of EU Fundamental rights and the susceptibility of those rights to abuse. Consideration is given to the major tax abuse practices and arrangements, accompanied by analyses of the responses of a selection of EU member states, and the role and impacts of judicial, state and commercial stakeholder interests. Consequent upon an examination of why past proposals have failed to attain either policy adoption or policy success, it is suggested that the legal concepts of abuse of rights, substance over form and proportionality may be of value in assessing and validating a corporate tax abuse proposal. It will be argued that Member State tax rules and policy initiatives to date have been unsuccessful in eradicating the effects of corporate tax abuse deriving from the exploitation of Fundamental Freedoms and that this failure is attributable to reasons of poor transactional data lineage and disclosure, unresolved political and judicial conflicts between balancing Member State rights with the Internal Market ideal and from a corporate culture that is incentivised to circumvent tax rules with limited recourse. Following an assessment of whether reform should focus on transactional based tax rules or on a broader legal framework to induce taxpayer behavioural changes, it is contended that EU corporate tax abuse can be addressed by rejecting the traditional ideals of tax harmonisation, formulary apportionment, and principles or rule-based tax law approaches as a complete solution. An effective scheme of reform should instead be based on Enhanced Disclosures and Attestation incorporating country-by-country reporting, additional reporting metrics and legal attestations, underpinned by civil and criminal penalties.
