The opposition Democratic Coalition is calling for the European Union to introduce a tax on multinational companies, Klára Dobrev, who heads the party list for the European Parliament election, said, commenting on an EP report approved on Tuesday which showed that seven European Union countries, including Hungary, were operating as tax heavens, enabling aggressive tax planning by corporations. Multinationals make use of the environment the government has developed and they pay an insignificant amount of tax, Dobrev said. Instead of serving the interests of Hungarians and the country, the government is aiding multinationals in a completely unprincipled manner, she added. This is why a United States of Europe is needed, so that EU countries can act together on this issue, Dobrev said. In response to a question, she said when any country introduces very low corporate tax, it harms EU taxpayers. Minimising tax often means avoiding tax, she added.
