TAX systems in most developing countries are far from optimal. Indeed, the need for adequate government revenues without excessive borrowing is sometimes in conflict with sound economic fundamentals. Most often these tax systems end up discouraging economic activity and distorting allocation of resources.

Developing countries face formidable challenges in their attempt to establish an efficient tax system.

First, most of the work force is employed either in agriculture or in the informal sector, including a rather large segment of the working population which is self-employed. As these economic activities are seldom documented, the base for taxation is attenuated and the possibility that the government can achieve high levels of revenues is virtually eliminated.

Second, in this day and age of computerisation, efficient tax administration requires well-educated and well-trained human resources which are typically lacking in developing countries.

Third, lack of reliable information on economic activity prevents major reforms of the tax system. Most developing countries, therefore, prefer marginal changes in their tax regime over major structural changes of the tax system.

Fourth, uneven distribution of income and wealth and the conjoining of economic and political power present a formidable barrier in the quest for a progressive tax regime. Most tax systems are regressive and are largely based on consumption rather than income. In other words, revenue generation is based mainly on indirect taxes with only a token contribution of direct taxes. Consequently, the burden of taxation falls most disproportionately on labour and not enough on capital.

The thrust of our argument is that developing countries tend to exploit whatever options are available rather than strive to establish a rational, modern and efficient tax system. The above observations notwithstanding, we should attempt to outline a tax regime which is least ‘harmful’ in the sense that it does not inhibit economic activity or cause major distortions in the allocation of resources.

Let us start by looking at the level of tax revenues. What is the optimal tax level? The measure that is generally used to determine the adequacy of the level of taxation is the tax-to-GDP ratio. This is, of course, typically low for developing countries.

However, when addressing the issue of the level of taxation, we tend to ignore the important question of what the optimal level of government spending ought to be. If, as in the case of Pakistan, revenues are used largely for non-development purposes, there is little that can be said about an optimal level of taxation. If, however, state-sponsored development is accorded any priority at all, we should recognise the fact that the process of economic development creates additional needs for public spending.

It may then be pertinent to link levels of taxation with the goals and stages of economic development. Therefore, our measure of the adequacy of the level of taxation must take into account the important issue of how revenues are to be used. It is also important to understand the flip side of this proposition, that an increase in public-sector spending which contributes to a higher level of growth also increases the economy’s ability to generate more revenues.

When we look at the composition of tax revenues with regard to economic development, we are confronted with several conflicting areas. The answer to this dilemma must come from the design of the development programme and not the other way round.

The issues involve the taxation of income relative to consumption, taxation of imports as against domestic consumption, allowable depreciation which affects the cost of capital and investment etc. Above all there is also a need to keep in mind the effect of a tax system on societal welfare and equity across various groups within society. In any case, the process of economic development should itself lead to a shift in the composition of revenues from consumption to income taxes or from a relatively regressive to a progressive taxation regime.

While on the subject of a taxation system which is least ‘harmful’, we should also address the issue of tax incentives. Most development literature contemplates some role for tax incentives in development design. However, many such incentives lead to rent-seeking activity and are prone to be misused or even abused.

Tax holidays, tax credits and investment allowances, accelerated depreciation, investment subsidies, duty drawbacks and indirect tax incentives such as exemption of raw materials and capital goods from sales tax etc., are some of the tax incentive schemes that are variously used, misused and abused in developing countries.

In addition, many of these tax incentives are instituted to attract foreign capital. But for foreign capital tax incentives are usually not as important as some other factors such as natural resources, political stability, good physical and human infrastructure etc. and are, therefore, of questionable value. The sole economic reason for such incentive schemes should be to compensate for and correct ‘market failures’.

To conclude our discussion we would suggest that keeping in mind the need for ever greater revenues and the relatively small base of taxation, developing countries should strive for tax systems which are least ‘harmful’. The need to allow the market forces to determine the allocation of resources should be tampered with only where market failures are perceived to exist. The design of the tax system should reflect this concern and minimise interference in the allocation process.

Here are some rules for an efficient and fair tax system. 1. Everybody that has an income should pay taxes, even if it is a rupee per year. 2. Keep the tax rates progressive but very low, starting at say 2% and topping off at 20%. 3. Businesses should pay taxes on their revenues and not on their profits, again the tax rates being progressive and very low. Every business must pay taxes. Also focus on providing only essential services by the government at the federal level. At the state level more services should be provided. Today the armed forces swallow the bulk of tax revenues and foriegn aid and that must be ended.

There are perfectly good models of taxation systems operative around the world available to emulate however difficulty arises in "honest" application to our model in Pakistan!

No more screwing the people who are already in the Tax-net. The Tax-net must be broadened to include all adult NIC holders ? The National Tax number should be based on NIC numbers. All the politicians, all Landlords and Agriculturists, Doctors, Lawyers must be brought under the Tax-net and it should be based on standard of living of an individual which can be gauged from the house he lives in and the type and number cars he and his family uses.

While I appreciate your ideas, none of the suggestions you've made are feasible. The first requires extensive documentation of the economy, especially the informal sector, which requires a substantial amount of resources and cannot happen in a short period of time. Plus, charging a nominal amount of tax after that monumental activity makes no sense in the cost-benefit analysis. The second , as a result of the first, would not bring in enough revenue for the government. The third is very counter productive, as it encourages deep vertical integration, which concentrates wealth even more. As a result of the 18th amendment, provinces DO provide most services, and much government revenue after defense and debt servicing is given to the provinces through the NFC. As for armed forces, I agree it must be cut, especially non defense expenses, but cutting too much too quickly in defense can bring us at our knees against terrorists.

No country should be classified as "developing" for more than 15 years. If the country doesn't become developed within 15 years or so, then there are some serious issues with that country's people, their economic model, and their view of the world. Taxation system is just one small facet of a much larger economic model being used by the people of a country. Therefore we must focus on the economic model first, and then only then, try to extract some money out of such system as "tax". Hope this is not too harsh of a comment.
