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.
Authored by Anil Nair and CV Madhukar PRS just concluded a workshop for MLAs from 50+ from more than a dozen states. What an AMAZING experience this was, even though this is the sixth such workshop we have held in this past year! This three day workshop on 'Mastering the Budget' was designed to help MLAs understand how to work with budget documents and numbers, find trends, understand the most critical macro numbers to track, etc. The second day of the workshop was tailored to reflect on the big thematic issues that have an impact on state finances. The Fiscal Responsibility and Budget Management Act, the Goods and Services Tax, the pattern of quantum of funds flow from the Centre to the state and local governments, the 13th Finance Commission, etc. The final day was devoted to doing an inter-state comparison of states on important budget parameters, and gleaning lessons from them. The idea for this budget workshop germinated at a previous workshop held at IIM Bangalore. The participating MLAs requested PRS to organise a special session on 'Mastering the Budget'. So this workshop was being organised as a result of their feedback. The choice of location was easy -- this was held at the National Institute for Public Finance and Policy in Delhi, which is amongst India's foremost institutions working on state budgets and public finance issues. Invitations were sent out to MLAs in several states. Responses started coming in within a few days, with about 70 confirmations. But there is always an uncertainty on the participation until the very last minute because elected politicians have immense demands on their time, at least some of which are unpredictable. So it was heartening to see that more than 50 MLAs came to the workshop representing 15 states -- Bihar, Rajasthan, Odisha, Uttar Pradesh, Assam, Kerala, West Bengal, Andhra Pradesh, Meghalaya, Tamil Nadu, Madhya Pradesh, Himachal Pradesh, Gujarat, Haryana, Manipur. The participants ranged from first time MLAs (about 50%), to a sitting Minister, a sitting Speaker, former Ministers, and senior leaders of political parties from some states. But the best part about the interaction in this workshop was that even on seemingly complex issues being discussed in the classroom, the MLAs were not mere recipients of 'gyan' that was being dished out. They had important questions to raise, and well articulated points of disagreement with the faculty, and brought in practical perspectives that might not have otherwise come up in the discussions. They went beyond the scope of the workshop to engage the economists on discussions on subjects like FDI in retail, state of India’s economy… Based on our experience of several workshops with MLAs, we want to share some observations about the participating MLAs: - There are MLAs in every state who want to understand substantive policy issues, and are willing to invest time and energy to do so. - When the MLAs participate in these workshops, they choose to do so on their own, and are not compelled by anyone to do so. - The sessions almost always begin and end on time, even in the freezing cold mornings in the Delhi winter. - The MLAs are very engaged in the discussions, ask questions, and bring in their experiences into the classroom discussions. - They keep partylines completely out of the substantive classroom discussions, and in the rare event that some new participant mentions anything partisan, other participants quickly ask him to avoid making any such mentions. In 2011, we have engaged with over 250 MLAs through these workshops and more. These workshops are just a starting point of what we hope will develop into a sustained, longer term engagement with MLAs on policy issues coming up in their states. In an important partnership with the Indian School of Business, Hyderabad, PRS has already conducted two workshops at the world class facilities at the ISB campus, and is planning to hold more in 2012. Just as PRS engages with about 300 MPs in Parliament, the hope is that more MLAs will be able to derive value from the work of PRS in the years to come, thereby making their decisions better informed.
