Tax relief mechanisms and the least taxed path for circulating income within a multinational enterprise.

(eng) When minimizing their overall tax liabilities, multinational enterprises exploit the various provisions of interjurisdictional tax arrangements, not hesitating to circulate flows indirectly and through multiple financial vehicles. This paper proposes to nest modelling such strategies into graph theory and network analysis. Such an exercise first calls for a precise taxonomy of multiple tax relief mechanisms and proves to be useful for computing strategy supported effective tax rates and investigating efficient design of interjurisdictional tax arrangements.
