Headquarter relocations and international taxation

Attention is increasingly being paid to the effects of corporation tax on the location of multinational headquarters. This research project addresses this issue. About 6 percent of all multinationals relocated their headquarters to another country between 1997 and 2007. We find that tax does play a role in these decisions. Based on a sample of 140 multinationals that relocated their headquarters over the past decade, and a control group of 1,943 multinationals that have not done so, we find that additional tax due in the home country upon repatriation of foreign profits has a positive effect on the probability of relocation. Specifically, empirical results suggest that an increase in the repatriation tax by 10 percentage points would raise the probability of relocation by 2.2 percentage points, equivalent to increasing the number of relocations by more than one third. The introduction of controlled foreign corporation legislation also has a positive effect on the number of relocations.
