The Corporate Tax Haven Index is a ranking of jurisdiction most complicit in helping multinational corporations underpay corporate income tax. The Corporate Tax Haven Index thoroughly evaluates each jurisdictions tax and financial systems to create a clear picture of the world’s greatest enablers of global corporate tax abuse, and to highlight the laws and policies that policymakers can amend to reduce their jurisdiction’s enabling of corporate tax abuse.
Jurisdictions are ranked by their CTHI value (Corporate Tax Haven Index value), which is calculated by combining a jurisdiction’s Haven Score and Global Scale Weight. A jurisdiction’s Haven Score is a measure of how much scope for corporate tax abuse the jurisdiction’s tax and financial systems allow and is assessed against 20 indicators. A jurisdiction’s Global Scale Weight is a measure of how much financial activity from multinational corporations the jurisdiction hosts. Combining a jurisdiction’s Haven Score and Global Scale Weight gives a picture of how much of the world’s corporate financial activity is put at risk of corporate tax abuse by the jurisdiction.
