We show that the parent-subsidiary structure of multinational firms created by cross-border mergers and acquisitions is affected by the prospect of international double taxation. Specifically, the likelihood of parent firm location in a country following a cross-border takeover is reduced by high international double taxation of foreign-source income. At the same time, countries with high international double taxation attract smaller numbers of parent firms. A unilateral elimination of worldwide taxation by the United States is simulated to increase the proportion of parent firms locating in the United States following cross-border mergers and acquisitions from 53% to 58%.
