Portuguese International Double Taxation Treaties

International double taxation is an obstacle to trade relations and to the free movement of goods, services, people and capital. The need to eliminate this obstacle has become more acute in the current context, dominated by new technologies and by the internet. By regulating the right of the countries involved to levy taxes, it is possible to avoid the relocation of income and capital to other countries merely for tax purposes and boost (economic and other) ties between the countries in question.
