This paper investigates the effect tax havens and other foreign jurisdictions have on the income tax rates of multinational firms based in the United States. We develop a new regression methodology using financial accounting data to estimate the average worldwide, federal, and foreign tax rates on worldwide, federal, and foreign pre-tax income for a large sample of US firms with and without tax haven operations. We find that on average US firms that disclosed material operations in at least one tax haven country have a worldwide tax burden on worldwide income that is approximately 1.5 percentage points lower than firms without operations in at least one tax haven country. Our results also show that US firms face a 4.4 percent current federal tax rate on foreign income whether or not they have tax haven operations. Finally, we find that US firms with operations in some tax haven countries have higher federal tax rates on foreign income than other firms. This result suggests that in some cases, tax haven operations may increase US tax collections at the expense of foreign country tax collections.
