My report was voted through by an overwhelming majority in the European Parliament in December 2015.
It focuses on three main areas where we can crack down on tax avoidance and tax evasion: bringing more transparency to tax matters; encouraging better coordination at the European level and increasing the convergence of the rules so that everyone is treated in the same manner.
1. Making multinational companies in Europe report exactly how much money they earn, and how much tax they pay, in every country where they do business
2. Introducing a new 'fair tax' label for those multinational companies who do play by the rules to show their customers that they pay their taxes
3. Making governments publish information about the arrangements they have come to with certain multinational companies regarding their taxes
4. Protecting those brave people who choose to 'blow the whistle' and inform the authorities or the public about harmful tax practices
1. Introducing a single set of European rules for businesses to calculate their all their profits made in the EU, and all the tax they owe to EU countries
2. Strengthening the European Council group which is charged with preventing aggressive tax avoidance but which has had limited impact in recent years
3. Making sure that governments can only introduce special tax arrangements for certain businesses if those businesses are genuinely contributing to the country's economy
4. Introducing a common tax registration number across all of Europe, so companies cannot hide from tax collectors by disguising their identity
1. Agreeing, once and for all, a definition of 'tax haven' so that we can name and shame those countries which are allowing companies to avoid paying tax
2. Banning any company which uses a tax haven from getting access to EU funding, like Common Agricultural Policy funds, European Investment Bank loans and structural funds.
3. Banning so-called 'letterbox companies', where a business simply puts a brass plaque on a building in a country with low taxes and claims it as their headquarters without locating many, or even any, staff there
4. Making European law clearer so that national governments can't arrange 'sweetheart deals' with certain companies at the expense of smaller businesses and ordinary taxpayers
