Member States find it increasingly difficult to protect their national tax bases from erosion as tax-planning structures have evolved to be particularly sophisticated. Such structures commonly consist of arrangements which are developed across various jurisdictions and move taxable profits towards more beneficial tax regimes or have the effect of reducing the taxpayer's overall tax bill. As a result, Member States often experience considerable reductions in their tax revenues, which hinder them from applying growth-friendly tax policies. It is therefore critical that Member States' tax authorities obtain comprehensive and relevant information about potentially aggressive tax arrangements. Such information would enable those authorities to react promptly against harmful tax practices and to close loopholes by enacting legislation or by undertaking adequate risk assessments and carrying out tax audits. However, the fact that tax authorities do not react to a reported arrangement should not imply acceptance of the validity or tax treatment of that arrangement.

For this reason, the Council of the European Union has adopted the Directive 2018/822 for amending the Directive 2011/16/EU as regards mandatory automatic exchange of information in the field of taxation.
