A European Parliament committee is demanding a fairer and more transparent corporate tax system across the EU.
The Special Committee on Tax Rulings has issued a report making a number of recommendations on corporate taxes.
They include making every EU country report on the profits multinationals are making - along with the taxes they are paying, and any subsidies they receive.
The aim is to ensure multinational firms pay their taxes where they make their profits.

Fine Gael MEP Brian Hayes says some of the Committee's recommendations are too draconian:
A protest took place outside the Department of Finance earlier today, calling on the Government to make its tax deals with multinationals clear.
It comes only days after a European Union ruling that found 'sweetheart' tax deals between multinational companies and member states are unlawful.
