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.
Recently, the Kelkar Committee published a roadmap for fiscal consolidation. The report stresses the need and urgency to address India’s fiscal deficit. A high fiscal deficit – the excess of government expenditure over receipts – can be problematic for many reasons. The fiscal deficit is financed by government borrowing; increased borrowing can crowd out funds available for private investment. High government spending can also lead to a rise in price levels. A full PRS summary of the report can be found here. Recent fiscal trends Last year (2011-12), the central government posted a fiscal deficit of 5.8% (of GDP), significantly higher than the targeted 4.6%. This is in stark contrast to five years ago in 2007-08, when after embarking on a path of fiscal consolidation the government’s fiscal deficit had shrunk to a 30 year low of 2.5%. In 2008-09, a combination of the Sixth Pay Commission, farmers’ debt waiver and a crisis-driven stimulus led to the deficit rising to 6% and it has not returned to those levels since. As of August this year, government accounts reveal a fiscal deficit of Rs 3,37,538 crore which is 65.7% of the targeted deficit with seven months to go in the fiscal year. With growth slowing this year, the committee expects tax receipts to fall short of expectations significantly and expenditure to overshoot budget estimates, leaving the economy on the edge of a “fiscal precipice”.

Committee recommendations - expenditure To tackle the deficit on the expenditure side, the committee wants to ease the subsidy burden. Subsidy expenditure, as a percentage of GDP, has crept up in the last two years (see Figure 2) and the committee expects it to reach 2.6% of GDP in 2012-13. In response, the committee calls for an immediate increase in the price of diesel, kerosene and LPG. The committee also recommends phasing out the subsidy on diesel and LPG by 2014-15. Initial reports suggest that the government may not support this phasing out of subsidies.

For the fertiliser subsidy, the committee recommends implementing the Department of Fertilisers proposal of a 10% price increase on urea. Last week , the government raised the price of urea by Rs 50 per tonne (a 0.9% increase). Finally, the committee explains the rising food subsidy expenditure as a mismatch between the issue price and the minimum support price and wants this to be addressed. Committee recommendations - receipts Rising subsidies have not been matched by a significant increase in receipts through taxation: gross tax revenue as a percentage of GDP has remained around 10% of GDP (see Figure 3). The committee seeks to improve collections in both direct and indirect taxes via better tax administration. Over the last decade, income from direct taxes – the tax on income – has emerged as the biggest contributor to the Indian exchequer. The committee feels that the pending Direct Tax Code Bill would result in significant losses and should be reviewed. To boost income from indirect taxes – the tax on goods and services – the committee wants the proposed Goods and Service Tax regime to be implemented as soon as possible.

Increasing disinvestment, the process of selling government stake in public enterprises, is another proposal to boost receipts. India has failed to meet the disinvestment estimate set out in the Budget in the last two years (Figure 4). The committee believes introducing new channels [1. The committee suggests introducing a ‘call option model’. This is a mechanism allowing the government to offer for sale multiple securities over a period of time till disinvestment targets are achieved. Investors would have the option to purchase securities at the cost of a premium. They also propose introducing ‘exchange traded funds’ which would comprise all listed securities of Central Public Sector Enterprises and would provide investors with the benefits of diversification, low cost access and flexibility.] for disinvestment would ensure that disinvestment receipts would meet this year’s target of Rs 30,000 crore.

Taken together, these policy changes, the committee believe would significantly improve India’s fiscal health and boost growth. Their final projections for 2012-13, in both a reform and no reform scenario, and the medium term (2013-14 and 2014-15) are presented in the table below: [table id=2 /]
