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 15th Lok Sabha is close to the end of its tenure. A key legislation that proposes major reforms in food security was listed for discussion in Parliament. The National Food Security Bill, 2011 has been scrutinised by a Standing Committee. In January, we compared the Standing Committee's recommendations with the provisions of the Bill. Since then, amendments to the Bill have been introduced in Parliament. Debates on the Bill have revolved around the method of delivering food security, the identification of beneficiaries and the financial implications of the Bill. Method of delivery The Bill aims to make the right to food a statutory right. It proposes to use the existing Public Distribution System (PDS) to deliver foodgrain to 75% of the rural and 50% of the urban population. However, the Bill also allows for cash transfers and food coupons in lieu of grains as mechanisms to deliver food security. While the PDS is known to suffer from leakages as high as 40%, cash transfers and food coupons are known to expose recipients to volatility and price inflation. Each method of delivery would have its own implications, financial and otherwise. The table below compares these methods of delivery.[i] [table id=7 /]
Identification The Bill does not universalise food entitlements. It classifies the population into two categories of beneficiaries, who shall be identified by the centre and states. Mechanisms that aim to target benefits to certain sections of the population have been prone to large inclusion and exclusion errors. A 2009 expert group study headed by N.C. Saxena that evaluated PDS, estimated that about 61% of the eligible population was excluded from the BPL list while 25% of APL households were included in the BPL list. Beneficiaries under the Food Security Bill will be identified through a similar process. It is unclear how these errors in identification of beneficiaries under the PDS will be addressed by the Bill. Financial implications - cost sharing between the centre and states A Bill that aims to deliver food security to a large section of the country would have significant financial implications. Costs shall be shared between the centre and states. Costs imposed on states (partial or full) include: nutritional support to pregnant women and lactating mothers, mid-day meals, anganwadi infrastructure, meals for children suffering from malnutrition, transport and delivery of foodgrains, creating and maintaining storage facilities, and costs associated with District Grievance Redressal Officers and State Food Commissions. Although the centre shall provide some assistance, states will have to bear a significant financial burden on account of implementation. It is unclear whether Parliament can require states to allocate funds without encroaching on the powers of state legislative assemblies. If a state chooses not to allocate the necessary funds or does not possess the funds to do so, implementation of the Bill could be seriously affected. The Standing Committee examining the Bill had recommended that an independent body, such as the Finance Commission, should be consulted regarding additional funds to be borne by states. The Right to Education Act with similar centre-state sharing of funds provides for such a consultation with the Finance Commission. Cost of implementation of the Bill Another contentious issue is the cost of implementing the Bill. The Bill estimates the cost at Rs 95,000 crore. However, experts have made varying estimates on the costs ranging from Rs 2 lakh crore to Rs 3.5 lakh crore. Ashok Gulati, Chairman of the Commission for Agricultural Costs and Prices, estimated the cost at 2 lakh crore per year whereas the Minister of Food, K.V. Thomas was reported to have estimated the cost at Rs 3.5 lakh crore. The passage of the food security Bill in Parliament will depend on the ability of the government to build consensus on these issues. It remains to be seen how the Bill is debated next Parliament session.
