The European Commission's proposal for a common consolidated corporate tax base (CCCTB) was published at the end of October 2016. It is a highly complex and technical proposal and time will be needed for all Member States to fully consider and discuss the proposal. As with all EU files, Ireland will engage constructively on the CCCTB proposal while critically analysing whether it is in our long-term interests. Analysis of the proposal is now underway to assess what the impact of the proposal would be on Irish corporation tax revenue. The proposal is also likely to be subject to significant changes as discussions between Member States begin under the Maltese Presidency. As always, tax remains a matter of Member State competence and unanimity is required before any tax proposals can be agreed.
