If one is a follower of current news in India, one must have come across the strange/political bonhomie/time/money wasting play acting by various politicians (usually state level) on the issue of imposition of Goods and Services Tax or the GST in India.
For a long time Indian tax system was considered complex and inefficient; to change this attitude/outlook there were many committees formed and many reports passed around. Some of the notable ones are Chelliah Tax Reforms Committee, 1991, Bagchi Report, 1994, Task Force on Indirect Taxes, 2002, Kelkar Committee Report, 2004. Almost all these reports without fail reported on the huge number of hurdles on calculating the correct figure of tax. The laws were complex, more than one law had jurisdiction on the same subject leading to confusion, add to that the bureaucratic apathy and no wonder India brought up the rear in the list of countries in providing an efficient tax system.
One of the best ways to have an efficient tax system is to follow the four principles of equity, certainty, convenience and economy in taxation as described by Adam Smith in 1776. Over years this has been modified by scholars to suit variations and to get a better adage (look at the table below as sourced out from a working paper).

However if we again look at the prevailing indirect tax system we would have to conclude that we are a far shy from anywhere near a perfect tax system. Look at our professional tax regime, if one is a professional one needs to pay professional tax but if the same service is provided by a non-professional then there is no tax except for the service tax. Also the very number of tax statutes to cover the gamut of over a 2 tier government structure is mind boggling.
In the Central Level there are:
- Custom Duty 
- Central Excise Duty 
- Service Tax 
- Central Sales 
- Telecom License Fee 
- Countervailing Custom Duty 
In the state level there are:
- State VAT 
- State Excise on few products 
- Luxury tax 
- Entry tax/octroi 
- Tax on consumption 
- Other ancillary taxes 
Some sighed in relief when VAT or the value added tax was sought to be introduced in 2000. However the relief was short again partly due to piecemeal nature of the legislation. There was serious holes in a legislation which sought to uniformize the indirect tax system. However the VAT system with its dual state VAT and CENVAT had scores of deficiencies namely:
To explain with an example, say a person in Kerala manufactures candle and he wants to sell them in West Bengal, so he first pays excise duty in Kerala and when he passes each state boundary he will pay octroi, after reaching West Bengal and locating a dealer once he sells the candle to the end consumers he will have to pay sales tax and will get no input credit for the excise and octroi under the current system. So the end cost of the candle would be many times higher than the original production cost. Under GST these interstate taxes would be abolished and there will be provision for input tax credit even when the material is sourced outside of the buying state. This would lead to the true economic integration of India as envisaged by the Constitution. Thus there was need for an upgrade, it came in the form of proposed Goods and Services Tax (GST). The first decision by the Joint Working Group (JWG) on GST was to propose a dual GST with all its pit falls it would have been nothing better than the existing VAT with availability of credit at all levels. However recently the JWG has proposed a three tiered system which would enable GST in India. From experience we know that one of the major problems of indirect tax system in India has been the multiplicity of laws and VAT sought to cure it but even a dual VAT was inefficient and so would be the proposed three tiered GST.
