The European Commission’s Proposals for a Common and Consolidated Corporate Tax Base
The CCCTB adopts a sound approach to taxation of multinationals (MNEs), by treating them in accordance with their business reality as unitary firms. It aims to identify the tax base of the whole corporate group, disregarding internal transactions between the affiliates, and to apportion the taxable profit according to factors reflecting the firm’s real activity (sales, assets, employees) in each country. In our view, this is the most effective way to end both competition between states to offer tax incentives, and tax avoidance by MNEs shifting income between affiliates to minimise tax.
In our view, however, the aim should be to create a level playing field in relation to tax on corporate profits not only within the EU but worldwide. Unless this is done, EU member states will continue to compete with each other to offer tax preferences to MNEs from outside the EU. They will also continue to be vulnerable to tax competition from jurisdictions not covered by the CCCTB (including the UK, after Brexit). The CCCTB can and should be recast so that it attributes to the EU as a whole a portion of the worldwide profits of MNEs reflecting their actual activities within the EU, as well as allocating that profit among EU states, using the same criteria.
We also propose a ‘compensation mechanism’, in case another country (e.g. the US) adopts the alternative which has been proposed for a destination-based cash-flow tax with a ‘border adjustment’.
We also warn against the 2-stage approach proposed by the Commission, and criticize the proposed ‘super-deduction’ for R&D expenditures, and the so-called Allowance for Growth and Investment. As some business groups have also argued, it is better to define the tax base broadly, allowing scope for cuts in the rate (which are already taking place), than to build in selective and distorting special allowances.
