On 14 February 2013 the European Commission announced the details of the financial transaction tax (FTT) that it proposes is adopted by the enhanced cooperation procedure.
The Commission’s press release is here; a set of Q&As is here; and the proposal itself is here. The FTT will be raised on an “issuance principle”, so will apply to shares of companies incorporated in the nine participating EU countries if those shares are traded on London, irrespective of the fact that the UK is not participating in (and opposes) the FTT.
Summary from the NYT here.
Next steps (from the Q&As): “Today’s proposal foresees the FTT for the 11 Member States entering into effect on 1 January 2014. Obviously, it depends on the Council reaching agreement on the proposal in time to respect this proposed implementation date. The European Parliament and the European Economic and Social Committee and National Parliaments will also be consulted, and national transposition would then be needed.”
