In the past few months, retail prices of petrol and diesel have consistently increased and have reached all-time high levels. On September 24, 2018, the retail price of petrol in Delhi was Rs 82.72/litre, and that of diesel was Rs 74.02/litre. In Mumbai, these prices were even higher at Rs 90.08/litre and Rs 78.58/litre, respectively.
The difference in retail prices in the two cities is because of the different tax rates levied by the respective state governments on the same products. This blog post explains the major tax components in the price structure of petrol and diesel and how tax rates vary across states. It also analyses the shift in the taxation of these products, its effect on retail prices, and the consequent revenue generated by the central and state governments.
What are the components of the price structure of petrol and diesel?
Retail prices of petrol and diesel in India are revised by oil companies on a daily basis, according to changes in the price of global crude oil. However, the price paid by oil companies makes up 51% of the retail price in case of petrol, and 61% in the case of diesel (Table 1). The break-up of retail prices of petrol and diesel in Delhi, as on September 24, 2018, shows that over 45% of the retail price of petrol comprises central and states taxes. In the case of diesel, this is close to 36%.
At present, the central government has the power to tax the production of petroleum products, while states have the power to tax their sale. The central government levies an excise duty of Rs 19.5/litre on petrol and Rs 15.3/litre on diesel. These make up 24% and 21% of the retail prices of petrol and diesel, respectively.
While excise duty rates are uniform across the country, states levy sales tax/value added tax (VAT), the rates of which differ across states. The figure below shows the different tax rates levied by states on petrol and diesel, which results in their varying retail prices across the country. For instance, the tax rates levied by states on petrol ranges from 17% in Goa to 39% in Maharashtra.
Note that unlike excise duty, sales tax is an ad valorem tax, i.e., it does not have a fixed value, and is charged as a percentage of the price of the product. This implies that while the excise duty component of the price structure is fixed, the sales tax component is charged as a proportion of the price paid by oil companies, which in turn depends on the global crude oil price. With the recent increase in the global prices, and subsequently the retail prices, some states such as Rajasthan, Andhra Pradesh, West Bengal, and Karnataka have announced tax rate cuts.
How have retail prices in India changed vis-à-vis the global crude oil price?
India’s dependence on imports for consumption of petroleum products has increased over the years. For instance, in 1998-99, net imports were 69% of the total consumption, which increased to 93% in 2017-18. Because of a large share of imports in the domestic consumption, any change in the global price of crude oil has a significant impact on the domestic prices of petroleum products. The following figures show the trend in price of global crude oil and retail price of petrol and diesel in India, over the last six years.
The global price of crude oil (Indian basket) decreased from USD 112/barrel in September 2012 to USD 28/barrel in January 2016. Though the global price dropped by 75% during this period, retail prices of petrol and diesel in India decreased only by 13% and 5%, respectively. This disparity in decrease of global and Indian retail prices was because of increase in taxes levied on petrol and diesel, which nullified the benefit of the sharp decline in the global price. Between October 2014and June 2016, the excise duty on petrol increased from Rs 11.02/litre to Rs 21.48/litre. In the same period, the excise duty on diesel increased from Rs 5.11/litre to Rs 17.33/litre.
Over the years, the central government has used taxes to prevent sharp fluctuations in the retail price of diesel and petrol. For instance, in the past, when global crude oil price has increased, duties have been cut. Since January 2016, the global crude oil price has increased by 158% from USD 28/barrel to USD 73/barrel in August 2018. However, during this period, excise duty has been reduced only once by Rs 2/litre in October 2017. While the central government has not signalled any excise duty cut so far, it remains to be seen if any rate cut will happen in case the global crude oil price rises further. With US economic sanctions on Iran coming into effect on November 4, 2018, India may face a shortfall in supply since Iran is India’s third largest oil supplier. Moreover, Organization of Petroleum Exporting Countries (OPEC) and Russia have not indicated any increase in supply from their side yet to offset the possible effect of sanctions. As a result, in a scenario with no tax rate cut, this could increase the retail prices of petrol and diesel even further.
How has the revenue generated from taxing petroleum products changed over the years?
As a result of successive increases in excise duty between November 2014 and January 2016, the year-on-year growth rate of excise duty collections increased from 27% in 2014-15 to 80% in 2015-16. In comparison, the growth rate of sales tax collections was 6% in 2014-15 and 4% in 2015-16. The figure below shows the tax collections from the levy of excise duty and sales tax on petroleum products. From 2011-12 to 2017-18, excise duty and sales tax collections grew annually at a rate of 22% and 11%, respectively.
How is this revenue shared between centre and states?
Though central taxes are levied by the centre, it gets only 58% of the revenue from the levy of these taxes. The rest 42% is devolved to the states as per the recommendations of the 14th Finance Commission. However, excise duty levied on petrol and diesel consists of two broad components – (i) excise duty component, and (ii) road and infrastructure cess. Of this, only the revenue generated from the excise duty component is devolved to states. Revenue generated by the centre from any cess is not devolved to states.
The cess component was increased by Rs 2/litre to Rs 8/litre in the Union Budget 2018-19. However, this was done by reducing the excise duty component by the same amount, so as to keep the overall rate the same. Essentially this provision shifted the revenue of Rs 2/litre of petrol and diesel from states’ divisible pool of taxes to the cess revenue, which is entirely with the centre. This cess revenue is earmarked for financing infrastructure projects.
At present, of the Rs 19.5/litre excise duty levied on petrol, Rs 11.5/litre is the duty component, and Rs 8/litre is the cess component. Therefore, accounting for 42% share of states in the duty component, centre effectively gets a revenue of Rs 14.7/litre, while states get Rs 4.8/litre. Similarly, excise duty of Rs 15.3/litre levied on diesel consists of a cess component of Rs 8/litre. Thus, excise duty on diesel effectively generates revenue of Rs 12.2/litre for the centre and Rs 3.1/litre for states.
In today's Opinion piece, in the Indian Express, we discuss how enacting hasty new legislation in response to public events may not be the answer. The recent spot fixing controversy in the Indian Premier League has brought the issue of betting in sports back into the limelight. As a result, public debate around betting, and steps that need to be taken to prevent the recurrence of such events, is gaining traction. The government's response to this incident has been somewhat predictable. The minister of state for sports has reportedly stated that his ministry is committed to putting in place new legislation to deal with the menace of fixing in sports. This approach to law making points towards a growing trend of initiating policy and legislative decisions as a reaction to public events. This is not something new. The Mumbai terror attack in 2008 was the catalyst for the enactment of the National Investigation Agency Act, and the brutal rape and murder of a young girl in Delhi led to the overhaul of India's penal code to ensure stricter penalties for crimes against women. Both these bills were passed without effective scrutiny, as they were not referred to a parliamentary standing committee for examination. Events in the country may, on occasion, highlight gaps in our policy and legislative framework. However, they often point out the ineffectiveness of existing laws and the lack of proper implementation. And that is not always a result of not having enough laws in the country. There are more than a 1,000 Central laws and over 15,000 state laws. The problem lies with our law-making process, which is ad hoc in nature. It is geared towards churning out legislation that is not entirely evidence based and does not take the feedback of different stakeholders into account. In its reports, the National Commission to review the working of the Constitution had observed that "our legislative enactments betray clear marks of hasty drafting and absence of Parliament scrutiny from the point of view of both the implementers and the affected persons and groups". Take, for example, the Gram Nyayalaya Act, which establishes village courts to provide people with easy access to justice and reduce the case law burden on the court system. Structured feedback from villagers, whom this act is trying to empower, prior to introducing the bill in Parliament would have given valuable insights about implementation challenges. A comprehensive study to examine the impact that village courts would have in reducing pendency in the judicial system would have provided hard numbers to substantiate what types of cases should be adjudicated by the village courts. A detailed financial analysis of the cost implications for the Central and the state governments for implementing the law would have helped policymakers decide on the scale and effectiveness of implementation. In the absence of these studies, there is no way to measure whether the law has been effective in giving villagers easy access to justice and in reducing the burden on the judicial system. The importance of stakeholder consultation was recently stressed by the parliamentary committee examining the land acquisition bill. In its report on the bill, the committee recommended that, "before bringing in any bill in future, the government should ensure wider, effective and timely consultations with all relevant and stakeholders so that all related issues are addressed adequately." Rajya Sabha MP N.K. Singh, while testifying before the parliamentary standing committee on the National Food Security Bill, had drawn the attention of the committee towards the need for an accurate financial memorandum accompanying the bill, to "avoid serious consequences in the implementation of the bill." The National Advisory Council has also suggested a process of pre-legislative scrutiny of bills and delegated legislation. In its approach paper, the Financial Sector Legislative Reforms Commission had suggested that delegated legislation should also be published in draft form to elicit feedback and that a cost benefit analysis of the delegated legislation should be appended to the draft. New laws can have a significant impact on the lives of people, so it is important that our law-makers enact "effective laws". For this to happen our law-making process needs to evolve. While there will always be public pressure for new laws, the solution lies in ensuring that the law-making process is robust, consultative and deliberative. The solution to addressing policy opportunities does not always lie in making new laws but in ensuring that whatever law is enacted is well thought out and designed to be effective.
