A minimum corporate tax rate would be harmful for both high and low tax countries

Conclusion

The corporate tax policy of the new EU member states does create pressures for some of the old member states to reduce their corporate taxes, in particular statutory corporate tax rates. But reacting to this pressure by enforcing mimimum tax rates in the EU would be counterproductive. It would slow down the economic catching up process in eastern Europe and question the competitiveness of the entire EU as a location for investment compared to other countries and regions in the world economy. There are potential benefits from more coordination in the field of corporate taxation, but this coordination should aim at removing tax obstacles to border-crossing investment and at reducing the compliance costs of the tax system. This requires targeted measures in the area of tax base coordination. Introducing minimum corporate tax rates, in contrast, would be harmful for both high and low tax countries in the EU.
