Non-Technical SummaryWhile profits are taxed, no immediate tax refund is granted if a corporation suffers losses.Losses can only be used to offset profits generated in other periods or by affiliated companies.The tax loss offset rules, however, significantly differ across countries. While only some countries grant a loss carryback option, a loss carryforward is always possible. Yet, in some countries the intertemporal loss offset is subject to time restrictions. Moreover, several countries have a group taxation which allows consolidation of profits and losses across affiliated firms.This paper analyzes in how far multinational firms factor the differently strict tax loss treatment rules into their investment decisions. We consider two effects of tax loss treatment. Our results suggest that the existence of a group taxation rule in particular exerts a positive influence on investments, which is even stronger for firms with a relatively high probability to suffer losses. Regarding the investment structure, a group taxation regime makes multinational groups distribute their investments across more subsidiaries. Concerning the intertemporal loss offset, we find that investment levels are significantly affected by tax loss offset rules if a subsidiary operates in an industry where the probability to suffer losses is high. Interestingly, a broad time limit until unutilized losses forfeit, however, does not seem to hinder investments.In the second part of our analysis, we trace effects of existing tax loss carryforwards on investment decisions. Our results suggest that the tax rate elasticity of investment actually is significantly reduced if a subsidiary can offset taxable profits with losses carried forward from previous periods. Abstract: We analyze the impact of tax loss treatment on the size and structure of multinational investments. Basically, two effects of tax loss treatment can be expected. First, firms make their investment decisions in the face of potential future losses. Then, the various types of conceivable loss offset provisions affect investment decisions. Secondly, existing loss carryforwards resulting from losses in the past affect the tax rate-elasticity of current investment decisions. The empirical analysis is based on data of German multinationals. The data is taken from the MiDi database provided by the German Central Bank (Deutsche Bundesbank). Re...
