Internal Debt and Multinationals’ Profit Shifting - Empirical Evidence from Firm-Level Panel Data
Abstract
This paper is concerned with the shifting of taxable profits by means of borrowing and lending between affiliates of multinational corporations. Empirical evidence is provided using microlevel panel data of virtually all German multinationals made available by the German Central Bank (Bundesbank). This comprehensive dataset allows us to exploit differences in taxing conditions in more than 150 countries over a period of ten years. The empirical results confirm a robust impact of tax-rate differences within the multinational group on the use of internal debt, supporting the view that internal debt is used to shift profits to low-tax countries. However, the tax effects are rather small. Given that the empirical literature finds profit shifting to be substantial, our estimates suggest that other strategies to shift income to low-tax countries are relatively more important.
