  • The European Commission proposed in late March changes to how digital businesses are taxed in the 28 member states of the EU.
  • The Commission — the EU's executive body — said at the time that digital companies pay on average an effective tax rate of 9.5 percent — compared to 23.2 percent for traditional businesses, which it said was not fair.
  • It then went on to suggest that even an added digital tax of 3 percent could generate about 5 billion euros ($5.99 billion) in revenues per year.

Luxembourg's finance minister believes that Europe should consult with the United States before going ahead with any taxation plans on large digital firms like Google.

"If a provisional taxation would lead to an escalation in the relationship with the main partners, and specifically with the United States, it would obviously be counterproductive, that's why I think the dialogue with the U.S. is so important," Pierre Gramegna told CNBC's Joumanna Bercetche Wednesday.
