Governor of Reserve Bank of India Shashikant Das has said that bringing petroleum products under GST will lead to initial sacrifices but will beget benefits in the long run. A report of State Bank of India has calculated that the initial loss of revenue will be to the tune of Rs one lakh crore. The question, however, remains wherefrom will the loss of one lakh crore revenue will be made up? This money will have to be collected from cloth, paper, bikes and other items. In other words, bringing petroleum under GST will not lead to a reduction of taxation. It will only lead to shifting of tax from petroleum to other commodities.

It needs to be noted that we import 85 percent of the oil consumed by us. Thus, reduction of tax on oil will lead to lower price, increased imports and will challenge our economic sovereignty. Instead of increasing, we need to reduce our consumption of oil so that we are less dependent on imports. Thus reduction of tax on oil as proposed by bringing it under GST will push us in the opposite direction and make us more dependent on imports.

In this backdrop we need to understand the statement made by Petroleum Minister Dharmendra Pradhan that bringing oil under GST will lead to the development of the oil sector. Indeed the reduction of price of oil will lead to higher consumption. Instead of installing solar panels, an industrialist may find it profitable to install a diesel generator. The question, however, is whether we should seek such development of the oil sector or we should, instead, seek the development of the solar energy sector? As said above, increased consumption of oil will be counterproductive. We should instead aim for improving the quality of oil consumption. Petroleum may be used only in such locations and uses that cannot be energized by alternative sources of energy such as solar or wind power. For example, I had purchased a small 500 watt petrol generator for my house in the eighties. At that time the solar panels were very expensive and not a viable option. Today, I have installed a 240 watt solar panel instead because solar panels have become relatively cheap while the price of petrol has become high. Similarly, commuters will use more of electric-driven metro and less of petrol-driven private cars if the price of petrol is high. The use of petroleum is justified only for such uses that cannot be served by other domestic and renewable sources of energy such as transporting goods to remote areas.

This much is true that bringing oil under GST will lead to the same price of oil in the entire country. An industrialist will not have to consider the price of oil while making a decision to establish a factory. This will lead to greater efficiency in allocation of resources. At the same time, this will remove the autonomy of the states in deciding the VAT collected on oil by them. At present some states collect taxes at a higher rate and use the revenues for securing public good such as forest conservation, water harvesting, vaccination or providing better law and order. Other states collect low VAT on oil. Their logic is that low VAT and low price of oil will encourage industrialists to establish factories in their state. The people will have higher disposable income and attain higher standard of living as well. Both considerations are justified. Welfare is obtained by high taxes and higher expenditures on public facilities; as well as by lower taxes and more encouragement to businesses. However, the people of a state that spends money efficiently will be benefitted by collecting high VAT; while the people of a state that spends money inefficiently will be at a loss by higher VAT. Thus, autonomy of VAT acts as an incentive for the states to spend efficiently. The State Government can explain to its taxpayers that they are getting benefits from the higher expenditures. Thus, autonomy acts as an incentive for the states to spend money efficiently.
