Historical Discussions on Taxation and Qualified Majority Voting

On 4 October 2003, the Intergovernmental Conference (IGC) on a Constitutional Treaty for the EU was launched. The discussions resulted in the approval of a Constitutional Treaty by the Heads of State and Government of the European Union on 18 June 2004. 

This webpage presents: 

  • the European Commission's position on the IGC of 2003-2004 and 
  • the positions taken by the Commission and other participants in the debate on qualified majority voting (QMV) that took place during the Convention on the Future of Europe, which provided a basis for the IGC discussions 

A series of arguments in favour of QMV in certain areas of taxation presented to the IGC, as well as useful links, are also attached. Since these arguments are evolutionary, it should be noted that they were drafted in 2002-2003 for the specific purpose of the work of the Convention and the IGC. 

Commission opinion

One topic of discussion at the IGC 2003-2004 was the question of introducing qualified majority voting on issues of taxation. The general rule in the European treaties is that EU countries must agree tax proposals unanimously before they can be adopted. 

The Commission proposed that there should be a move from unanimity to qualified majority voting f similar decision-making arrangements (consensus within the European Council or agreement by or proposals in a limited number of tax fields: proposals necessary for the proper operation of the Internal Market, proposals to combat tax fraud and evasion, and proposals related to the protection of the environment. 

At the Intergovernmental Conference (IGC), the Commission expressed the following views on the need for a limited move from unanimity voting to qualified majority voting for tax proposals: 

Unanimity vs QMV

Within the framework of the treaties of the European Community and the European Union (as well as under the constitutional treaty approved by Heads of State and Government following the IGC), all tax decisions to be taken at European level are subject to the unanimity rule. That is, all Member States must agree on any measure adopted in the taxation field. 

Qualified majority voting implies that a European law is adopted as soon as a certain threshold of votes in the Council is reached. Voting is weighted on the basis of an EU country's population and corrected in favour of less-populated countries.

More information on QMV

Some EU countries do not think it desirable to extend qualified majority voting to taxation. This view is not shared by the Commission, which considers that QMV is necessary in some areas of taxation. 

In an enlarged EU of (then) 25 Member States, retaining unanimity for all taxation decisions may make it impossible to achieve any of the tax co-ordination necessary for Europe. This can be easily demonstrated through examples. 

See: The limits of unanimity voting in taxation 

It is important to stress that qualified majority voting does not imply harmonisation of taxation across Europe. Nor does it mean an increase in taxation. QMV in taxation is aimed at ensuring the compatibility of the Member States' tax systems with each other and with the Treaties. 

The justifications for modifying decision-taking in taxation are further explained in the frequently asked questions (FAQs).

Positions expressed in the Convention on the Future of Europe

The Convention on the Future of Europe met between March 2002 and June 2003 to make recommendations on the key issues arising for the European Union's future development. 

The Convention submitted its recommendations in the form of a new draft Constitutional Treaty, replacing and modifying the content of the existing Treaties to the Thessaloniki European Council, which welcomed it and considered it to be a good basis for starting the IGC. 

In the context of the Convention on the Future of Europe, taxation was the subject of in-depth discussion in the workgroup on 'Economic governance'. Subsequently, in plenary session, the participants presented their points of view and discussed the proposals of the Convention Praesidium. 

The Commission representatives wished to amend the taxation articles in the draft constitution treaty. The information presented here is relatively technical.
