"For several years the financing of the European budget has been under challenge: it is hard to understand and overly dependent on the States. There is nothing to distinguish national contributions, levied from the Member States' tax revenues from the Union's so-called "own resources" as anticipated in the treaties. In 2005 the European Council committed to look into the issue and since then the European Parliament has made it its main priority. In 2011 the European Commission presented reform proposals."
