The document summarizes questions from 11 EU member states to the European Commission regarding its proposal for implementing enhanced cooperation on a financial transaction tax (FTT). Specifically, the member states seek clarification in the areas of: (1) collection of the tax and establishing common rules, (2) ensuring cooperation from non-EU countries, and (3) application of the tax to various financial instruments including government bonds, non-government bonds, and transactions not involving financial institutions. The member states ask how the Commission's impact assessment calculated various estimates and what effects the tax may have on different bond and debt markets.
