This paper explores the economic consequences of proposed EU reforms for a common consolidated corporate tax base. The reforms replace separate accounting with formula apportionment as a way to allocate corporate tax bases across countries. To assess the economic implications, we use a numerical...

This report adopts an applied general equilibrium model for the EU27 to study the economic implications of a common corporate tax base in the European Union, either or not combined with consolidation and formula apportionment. The analysis of the common corporate tax base (CCTB) centres around...

This article assesses the economic implications of the introduction of consolidation with formula apportionment in the European Union under alternative enhanced cooperation agreements. We find that the consolidation is likely to yield a small aggregate welfare gain in Europe, but that not all...

This paper examines the likely impact of a proposed formula apportionment system for corporation tax in the EU on the inbound investment of US multinational companies. We pay attention to tax planning strategies that may be employed by US multinationals and investigate whether effective tax...

We propose a methodology for assessing the neutrality of corporate tax reform proposals in an open economy. The methodology identifies variation in effective tax rates to assess the proximity of a tax system to capital export neutrality (CEN) and to market neutrality (MN, which holds if all...

This paper assesses the efficiency properties of recent corporation tax re- form proposals of the European Union to introduce international loss consolidation and formula apportionment. We extend the effective tax rate methodology of Devereux and Griffith (1999) to allow for a potential loss and...

The European Commission proposes to replace the current system of taxing corporate income of separate accounting by a two-step 'consolidate and apportionment' procedure. This paper uses a large set of unconsolidated firm-level data to assess the likely impact on corporate tax revenues in each...
