ABSTRACT: The development of world trade along with accelerated globalization has an effect not only on economic development or the strengthening of international cooperation but also facilitated sophisticated mechanisms by which the payment of tax obligations by multinational companies is circumvented. Transfer pricing and tax havens, considered both individual and combined practices, negatively affect a country's ability to implement fiscal policy and improve budget revenue collection capacity. The problem is even greater in the case of states with a fragile economy, where the dynamics of development is vitally related to the elimination of legal, immoral, or illegal tax evasion practices. The Transfer pricing mechanism has also been optimized to handle taxable transactions between companies affiliated to a particular group. Multinational companies avoid taxes by overestimating imports and underestimating exports, thus managing to distribute revenues in various regions of the globe that have great tax advantages.
