Tax treaty shopping beneficial

Multinational enterprises are able to reduce their international corporate tax burden with 6 percent by routing their investments through third countries, the so-called "treaty shopping". Thus treaty benefits can be reaped which are unavailable through direct tax routes.

This result is found by researchers Maarten van ’t Riet and Arjan Lejour of CPB Netherlands Bureau for Economic Policy Research, using a novel method applied to a network of tax treaties for 108 countries. The United Kingdom heads the list of central countries in the international tax network, while the Netherlands is ranked fourth.

The network analysis takes account of the double tax relief methods that countries apply, as well as bilateral tax treaties. Their desired effect indeed materializes: a substantial reduction of possible double taxation on international dividends. If multinationals use the potential treaty benefits by structuring their tax liabilities through conduit countries, they reduce their tax burden even further. The worldwide average remaining double tax rate is 6 percent. This comes on top of the corporate income tax due in the host country of the investments.

For some countries all tax revenues on international dividends disappear as a consequence of treaty shopping, while the additional tax revenues for conduit countries are less than half percent of worldwide dividend flows.

A policy simulation with the network method demonstrates that treaty shopping has a strong dampening effect on the double tax rates for multinationals. This suggests that possible actions against tax avoidance on dividend flows requires large scale international cooperation.
