Corporate Income Taxation and Investment: A Review of Empirical Findings and Policy Issues in the EU Context

This brief discusses how reforms in Member States related to taxation, in particular business taxation, can contribute to spurring investment, while respecting the need to maintain public revenue in a context of high debt and significant fiscal needs. After describing how corporate taxation contributes to the public finances of EU countries, the brief surveys recent studies analysing the impact of corporate taxation on business investment. Recent studies suggest that cuts to statutory tax rates represent a costly way of spurring investment. Targeted incentives for investment, including investment tax credits and accelerated depreciation rules, may be a more cost-effective way to spur investment, although their stimulative effects are not sufficient to counterbalance the static fiscal costs. Business taxation based on tax bases other than profits (e.g. on real estate or turnover) has also been found to be more distortive and harmful to investment than profit-based taxes. Specific aspects of the tax code may open the way for aggressive tax planning (ATP) whereby taxpayers reduce their corporate tax liability through arrangements that may be legal but are in contradiction with the intent of the law. Through the European Semester and reforms in national Recovery and Resilience Plans, the EU has achieved some success in fighting ATP in a number of countries, although some issues remain.
