In India taxes are mainly of two types – Direct and Indirect. Taxes are imposed by both central and state governements. Direct taxes contribute more to revenue. It mainly comprises of Income-tax and Corporate tax. 

Indirect taxes in the pre-GST era consisted of excise duty, cess, state VAT, central sales tax, purchase tax, luxury tax, entertainment tax, etc. They were levied by both centre and state. Interstate sales of goods were taxed by the centre government. 

This led to the overlapping of taxes as well a lot of confusion. It also resulted in a cascading effect known as the “tax on tax” burden. 

Then came Goods and Services Tax (GST). GST is a tax on goods as well as on services. It is an indirect tax. It has replaced many indirect taxes in India such as excise duty, service tax, VAT, etc. It came into effect in 2017. It can be levied at each point of sale or provision of service. 

Mechanism of GST:

Assume a uniform GST of 16% for the following example.

At the time of sale of goods or providing the services, the seller or the service provider can claim the input credit of tax he has paid while purchasing the goods or providing the service. 

In this system, not only the goods but services are also involved and the rate of tax on goods and services are generally the same.

The burden of “tax on tax” in the pre-existing central excise duty and sales tax system of state government can be explained as under:

Questions / Answers


q1. What are the components of GST?


There are three taxes – CGST, SGST, ISGT
 CGST – On intrastate sales i.e transactions happening within a state, tax collected by the central government 
 SGST – On intrastate sales i.e transactions happening within a state, tax collected by the state government 
 IGST – On interstate sales i.e from one state to another, tax collected by the central government


q2. How is the revenue distributed between states and the centre?


For the sale within the state, revenue is shared equally between the state and the centre (CGST + SGST)
For the sale to another state, there is only one type of tax (central). The centre shares the revenue (IGST) based on the destination of the goods. 


q3. Is GST technologically driven?

q5. GST compensation issue faced by the government?


A GST is in the early stages and its effect still needs to be understood fully. There was a huge outcry with respect to its implementation because of the lack of clarity. Moreover, with the economic slowdown, GST collections have been down. GST loss has been incurred by the states. As per GST compensation act 2017, states need to be compensated for any loss in revenue until 2022. 


q6. How does the GST system work?


Most countries have a single GST system i.e a single rate is applied. One single tax is collected by merging central and state taxes. India has a dual GST structure with CGST and SGST in picture. The main aim was to eliminate the tax on tax that unnecessarily increased the cost for the customer. In pre-GST regime, the customer ended up paying a higher amount of total taxes. 


Q7. What are the problems pertaining to GST?
