In the current era of cross -border transactions across the world, due to unique growth in international trade and commerce and increasing interaction among the nations, residents of one country extend their sphere of business operations to other countries where income is earned. One of the most significant results of globalization is the noticeable impact of one country’s domestic tax policies on the economy of another country. This has led to the need for incessantly assessing the tax regimes of various countries and bringing about indispensable reforms. Therefore, the consequence of taxation is one of the important considerations for any trade and investment decision in any other countries. Fiscal jurisdiction is often the most aggressively protected jurisdiction in Bangladesh. Consequently, even in times when economies are going global & borders vanishing, leading to liquid movement of goods, services and capital, double taxation is still one of the major obstacles to the development of inter-country economic relations. Bangladesh are often forced to negotiate and accommodate the claims of other nations within their heavily defended fiscal jurisdiction by the means of double taxation avoidance agreements, in order to bring down the barriers to global trade.
