Why do we have taxes? The simple answer is that, until someone comes up with a better idea, taxation is the only practical means of raising the revenue to finance government spending on the goods and services that most of us demand. Setting up an efficient and fair tax system is, however, far from simple, particularly for developing countries that want to become integrated in the international economy. The ideal tax system in these countries should raise essential revenue without excessive government borrowing, and should do so without discouraging economic activity and without deviating too much from tax systems in other countries.
Developing countries face formidable challenges when they attempt to establish efficient tax systems. First, most workers in these countries are typically employed in agriculture or in small, informal enterprises. As they are seldom paid a regular, fixed wage, their earnings fluctuate, and many are paid in cash, "off the books." The base for an income tax is therefore hard to calculate. Nor do workers in these countries typically spend their earnings in large stores that keep accurate records of sales and inventories. As a result, modern means of raising revenue, such as income taxes and consumer taxes, play a diminished role in these economies, and the possibility that the government will achieve high tax levels is virtually excluded.
