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.
Sakshi of PRS Legislative Research discusses the government's ordinance-making power in the context of the National Food Security Ordinance in an Indian Express opinion editorial. On Wednesday, the Union cabinet approved the food security ordinance. The government has already introduced a National Food Security Bill in Parliament in December 2011. Parliamentary consideration on the bill has been initiated with the standing committee submitting its recommendations and the government proposing amendments to the law. After being listed on several occasions for discussion, members of Parliament began debating the bill in the last few days of the 2013 budget session. In spite of all this, the government has chosen to promulgate an ordinance. In all likelihood, Parliament will reconvene in a few weeks for the monsoon session. In this context, it would be useful to understand the ordinance-making power of government and its usage in the recent past. Under the Constitution, the power to make laws rests with the legislature. The executive has been given the power to make laws when Parliament is not in session and "immediate action" is necessary. In such scenarios, the president can issue an ordinance on the advice of the executive, to have the same effect as an act of Parliament. In the 1980s, the Supreme Court was confronted with a case where a state government repeatedly re-promulgated ordinances that had lapsed in previous assembly sessions. This led the SC to examine the ordinance-making power of government. The SC reasserted the constitutional principle that the primary law-making power rests with the legislature and not the executive. The executive is only given the legislative power to issue an ordinance to meet an "emergent situation". Such a situation arose in 2011 when, given that students were awaiting their degrees on the completion of their course, the government issued an ordinance to grant IIIT-Kancheepuram the status of an institute of national importance so that students could be awarded their degrees. Data over the last 60 years indicates that the highest number of ordinances, 34, were passed in 1993. Over the 15th Lok Sabha (2009-2013), there have been 16 ordinances, indicating a decline in the number of ordinances being issued every year. Once an ordinance is framed, it is to be laid before Parliament within six weeks of its first sitting. Parliament is empowered to either choose to pass the ordinance as law or let it lapse. Once the ordinance is laid in Parliament, the government introduces a bill addressing the same issue. This is typically accompanied by a memorandum tabled by the government, explaining the emergent circumstances that required the issue of an ordinance. Thereafter, the bill follows the regular law-making process. If Parliament does not approve the ordinance, it ceases to exist. The drafters of the Constitution created this check on the law-making power of the executive to reinforce the notion that law-making will remain the prerogative of the legislature. Earlier this year, in the aftermath of the Delhi gangrape, public pressure led the government to appoint a three-member committee under the late Justice J.S. Verma to suggest changes to laws relating to crimes against women. An amendment bill had already been pending in Parliament. In spite of this, the government brought in the Criminal Law Ordinance, giving effect to some of the committee's recommendations. Once Parliament reconvened, the government introduced a fresh bill replacing the ordinance, seeking to create more stringent provisions on matters related to sexual offences. It passed muster in both Houses. While the Criminal Law Ordinance is an illustration of an ordinance successfully passing through Parliament, there are examples of ordinances that have lapsed because they were not approved by Parliament. In 2004, a week after the winter session ended, the government issued an ordinance to give the Pension Fund Regulatory and Development Authority statutory powers as a regulator. Due to political opposition, the ordinance lapsed and, subsequently, the bill lapsed at the end of the 14th Lok Sabha. The government re-introduced it as a bill in 2011, which is currently pending in Parliament. Although the government has used its power to issue a food security ordinance, the law guaranteeing this right will have to stand scrutiny in Parliament. What remains to be seen is how Parliament debates the right to food in the upcoming monsoon session. That should give us some food for thought.
