Common Corporate Tax Base
(CCTB).
EU
The European Commission proposed in March 2011 the Common Consolidated Corporate Tax Base (CCCTB). A single set of harmonised rules for calculating taxable profits, to replace the current different, national corporate tax rules in each EU Member State.
A purpose of the common tax base would be to make tax competition among Member States more transparent.
After consultation the common consolidated corporate tax base (CCCTB) project was re-launched in a two-step approach, with the publication on 25 October 2016 of two new interconnected proposals:
- on a common corporate tax base (CCTB), and
- on a common consolidated corporate tax base (CCCTB).
Building on the 2016 CCTB proposal, the 2016 CCCTB proposal introduced the consolidation aspect of this double initiative.
The 2016 CCTB provides for the determination of a single set of rules for calculation of the corporate tax base. Companies operating across borders in the EU would no longer have to deal with 28 different sets of national rules when calculating their taxable profits. The intention is that the proposed CCTB is a step on the way towards re-establishing the link between taxation and the place where profits are made, via an apportionment formula to be introduced through the new CCCTB proposal.
