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.
The last few days have seen repeated disruptions in Parliament. In an Opinion Editorial published in the Indian Express, Chakshu Roy of PRS Legislative Research discusses the impact of the current disruptions on Parliament. His analysis points to how disruptions are an opportunity lost to hold the government accountable and to deliberate on significant legislative and policy issues. The second half of the budget session commenced last week with hardly any business transacted due to disruptions on different issues. This is not new. The 15th Lok Sabha has seen entire parliamentary sessions lost without any work being done. As it nears the end of its term, Parliament's productive time stands at 70 per cent, which is significantly lower than that of previous Lok Sabhas. As disruptions in Parliament have become routine, public reaction to such disruptions has also become predictable. Figures depicting the quantum of taxpayers' money lost every hour that Parliament does not function start doing the rounds, and the cry for docking the salary of disrupting members of Parliament becomes louder. What does not get adequate attention is the opportunity lost for holding the government accountable and deliberating on important legislative and policy issues. MPs are required to keep the government in check and oversee its functioning. One of the ways in which they do so is by asking ministers questions about the work done by their ministries. Ministers respond to such questions during the first hour of Parliament, which is known as question hour. During this hour, 20 questions are slotted for oral responses by ministers. Based on the response, MPs can cross-question and corner the minister by asking supplementary questions. On certain occasions, they are also able to extract assurances from the minister to take action on certain issues. When question hour is disrupted, not only are these opportunities lost, it also leads to ineffective scrutiny of the work done by the various ministries of the government. Last week, some of the questions that could not be orally answered related to four-laning of highways, performance of public sector steel companies, supply of food grains for welfare schemes, and generic versions of cancer drugs. In 2012, out of the 146 hours allocated for question hour in both Houses of Parliament, roughly only 57 hours were utilised. Since the beginning of the 15th Lok Sabha in 2009, approximately 43 per cent of the allocated time has been spent on question hour. When Parliament is disrupted regularly, its capacity to make laws is affected. Excluding routine financial legislation, since 2009, the government had planned to introduce 390 bills. So far, it has been able to introduce only 187 of them. It had also planned to have 365 bills scrutinised and passed by Parliament. So far, 96 of them have received parliamentary approval. Disruptions in Parliament also eat into the time available for discussing a bill in the house. In Lok Sabha, roughly 35 per cent of bills were passed with an hour or less of debate, a case being the sexual harassment bill, which was passed by Lok Sabha in September of last year in 16 minutes. Some would argue that since parliamentary committees scrutinise most bills in detail, there is no harm done if the bills are not debated in the House. However scrutiny of a bill behind closed doors is hardly a substitute for spirited debates on the merits and demerits of a bill on the floor of the House. Currently there are 115 bills awaiting parliamentary scrutiny and approval. Important social and economic legislation is currently pending before Parliament. The food security bill, the land acquisition bill, the companies and the goods and services tax bill are just a few of them. Out of the laundry list of pending bills, some are political and may be stuck in Parliament till consensus around them can be built. But there are a number of bills that are administrative in nature, and have no political undercurrents and are possibly not coming up for discussion because of the limited time that is available for legislative debate on account of frequent disruptions. In September 1997, to celebrate the golden jubilee of the country's Independence, a special session of Parliament was convened. At this special session, MPs had resolved to preserve and enhance the dignity of Parliament by adhering to the rules of procedure of Parliament relating to the orderly conduct of parliamentary proceedings. Last year, Parliament completed 60 years since its first sitting. To mark the occasion, another special session of both Houses was convened, where MPs had resolved to uphold the dignity, sanctity and supremacy of Parliament. Ensuring that the proceedings of both Houses run smoothly so that Parliament can discharge its responsibility effectively is the best way of ensuring its supremacy. The question that needs to be asked is whether our members of Parliament are ready to stand by the resolutions that they voluntarily adopted.
