Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what assessment he has made of the potential implications of the EU Economic and Monetary Affairs Committee's decision of 27 May 2016 to introduce European Taxpayer Identification Numbers for the administration of tax in the UK.

To date there has been no formal proposal for a European Tax Identification Number (EU TIN), and this European Parliament committee has no power to put forward a proposal in the tax space.

Tax is a Member State competence. All Member States have to agree with unanimity on tax proposals, so if a proposal were brought forward regarding an EU TIN the UK would need to formally agree in order for it to proceed.
