On Friday, the ECOFIN Council will discuss the report that the High Level Group of Experts, chaired by Mario Monti, has recently published. There is, in any case, a need for action: the Union's current financing system needs to be simplified. In addition, the United Kingdom, a large net contributor, will leave the EU.

EU taxation is not an alternative, however. As long as the EU budget is financed mainly through contributions from the Member States, national governments have an interest in an economically effective distribution of EU funds. The introduction of a European tax would weaken this interest, as EU revenues would flow directly into the Brussels budget. There is only an incentive to redeploy and reprioritize funding and finance projects which are of rising interest to the whole of Europe, when the EU budget restriction meets the fiscal interest of the Member States. Projects of rising interest are a common foreign and security policy and a common refugee policy.

At the moment, the EU's annual budget consists mainly of three sources: the first one is the EU’s single own source of income, namely revenues from customs duties levied on the import of goods from third countries into the single market; the second source is the national contributions which are based on the value added tax (VAT) and are paid by the Member States to the Brussels budget; and the largest share of the budget stems from contributions paid by the Member States to the EU according to their gross national income (GNI). Last year, GNI contributions accounted for almost EUR 104 bn, with an EU budget of EUR 143.5 bn.

A reform of the EU funding should abolish the contributions based on the VAT. The EU budget should only be based on the revenues from customs duties and the GNI contributions. The latter have the great advantage that they follow the economic performance of an economy.
