Corporate Taxation and the Choice of Patent Location within Multinational Firms

Abstract

This paper investigates whether corporate taxation affects the location of patents within a multinational group. We exploit a unique dataset which links patent data from the European Patent Office to micro panel data on European firms for 1995-2003. Our results suggest that the host country’s corporate tax rate exerts a negative effect on the number of patents filed by a multinational subsidiary. The effect is statistically significant and quantitatively large and turns out to be robust against controlling for affiliate size. The findings prevail if we additionally account for royalty withholding taxes. Moreover, binding ‘Controlled Foreign Company’ rules tend to decrease the number of patent applications.corporate taxation, multinational enterprise, profit shifting
