Taxing multinationals beyond borders: Financial and locational responses to CFC rules
Journal of Public Economics, 173, 44-71
Using a large panel dataset on worldwide operations of multinational firms, this paper studies one of the most advocated anti-tax-avoidance measures: Controlled Foreign Corporation rules. By including income of foreign low-tax subsidiaries in the domestic tax base, these rules create incentives to move income away from low-tax environments. Exploiting variation around the tax threshold used to identify low-tax subsidiaries, we find that multinationals redirect profits into subsidiaries just above the threshold and change incorporation patterns to place fewer subsidiaries below and more above the threshold. Roughly half of the resulting increase in global tax revenue accrues to the rule-enforcing country.

The impact of CFC rules
This research project examines how Controlled Foreign Corporation (CFC) rules affect the profit declared by multinational companies in low tax jurisdictions. CFC rules essentially allow the jurisdiction of residence of a parent company to tax the income of its subsidiaries in low-tax jurisdictions. This creates incentives for multinationals to move income away from those jurisdictions.
Typically, jurisdictions use a tax rate threshold to identify low tax jurisdictions (and hence subsidiaries). The figure below shows an adjusted measure of profit (left axis, filled circles) around this threshold for subsidiaries of parent companies in a number of countries including Germany, France and the United Kingdom. It is evident from the figure that profit rates are significantly higher in jurisdictions above the threshold, suggesting that multinationals tend to report less income in low tax rate jurisdictions subject to CFC rules. The figure also shows the tax incentives around this threshold which ultimately generate this response (right axis, hollow circles).
The paper also presents evidence that new subsidiaries tend to be placed in jurisdictions that are not subject to CFC rules, suggesting that the rules affect the location of both profits and real activity. These results suggest that CFC rules are therefore an effective tool.
