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.
Earlier this week, Rajya Sabha passed the Airports Economic Regulatory Authority of India (Amendment) Bill, 2019, and the Bill is now pending in Lok Sabha. The Bill amends the Airports Economic Regulatory Authority of India Act, 2008. The Act established the Airports Economic Regulatory Authority of India (AERA). AERA regulates tariffs and other charges for aeronautical services provided at civilian airports with annual traffic above 15 lakh passengers. It also monitors the performance standard of services across these airports. In this post, we explain the amendments that the Bill seeks to bring in and some of the issues around the functioning of the regulator.
Why was AERA created, and what is its role?
Few years back, private players started operating civilian airports. Typically, airports run the risk of becoming a monopoly because cities usually have one civilian airport which controls all aeronautical services in that area. To ensure that private airport operators do not misuse their monopoly, the need for an independent tariff regulator in the airport sector was felt. Consequently, the Airports Economic Regulatory Authority of India Act, 2008 (AERA Act) was passed which set up AERA.
AERA regulates tariffs and other charges (development fee and passenger service fee) for aeronautical services (air traffic management, landing and parking of aircraft, ground handling services) at major airports. Major airports include civilian airports with annual traffic above 15 lakh passengers. In 2018-19, there were 32 such airports (see Table 1). As of June 2019, 27 of these are being regulated by AERA (AERA also regulates tariffs at the Kannur airport which was used by 89,127 passengers in 2018-19). For the remaining airports, tariffs are determined by the Airports Authority of India (AAI), which is a body under the Ministry of Civil Aviation that also operates airports.
What changes are being proposed in the Bill?
The Bill seeks to do two things:
Definition of major airports: Currently, the AERA Act defines a major airport as one with annual passenger traffic over 15 lakh, or any other airports as notified by the central government. The Bill increases the threshold of annual passenger traffic for major airports to over 35 lakh.
Tariff determination by AERA: Under the Act, AERA is responsible for determining the: (i) tariff for aeronautical services every five years, (ii) development fees, and (iii) passengers service fee. It can also amend the tariffs in the interim period. The Bill adds that AERA will not determine: (i) tariff, (ii) tariff structures, or (iii) development fees, in certain cases. These cases include those where such tariff amounts were a part of the bid document on the basis of which the airport operations were awarded. AERA will be consulted (by the concessioning authority, the Ministry of Civil Aviation) before incorporating such tariffs in the bid document, and such tariffs must be notified.
Why is the Act getting amended?
The Statement of Objects and Reasons of the Bill states that the exponential growth of the sector has put tremendous pressure on AERA, while its resources are limited. Therefore, if too many airports come under the purview of AERA, it will not be able to perform its functions efficiently. If the challenge for AERA is availability of limited resources, the question is whether this problem may be resolved by reducing its jurisdiction (as the Bill is doing), or by improving its capacity.
Will the proposed amendments strengthen the role of the regulator?
When AERA was created in 2008, there were 11 airports with annual passenger traffic over 15 lakh. With increase in passenger traffic across airports, currently 32 airports are above this threshold. The Bill increases the threshold of annual passenger traffic for major airports to over 35 lakh. With this increase in threshold, 16 airports will be regulated by AERA. It may be argued that instead of strengthening the role of the regulator, its purview is being reduced.
Before AERA was set up, the Airports Authority of India (AAI) fixed the aeronautical charges for the airports under its control and prescribed performance standards for all airports and monitored them. Various committees had noted that AAI performed the role of airport operator as well as the regulator, which resulted in conflict of interest. Further, there was a natural monopoly in airports and air traffic control. In order to regulate the growing competition in the airline industry, and to provide a level playing field among different categories of airports, AERA was set up. During the deliberations of the Standing Committee examining the AERA Bill, 2007, the Ministry of Civil Aviation had noted that AERA should regulate tariff and monitor performance standards only at major airports. Depending upon future developments in the sector, other functions could be subsequently assigned to the regulator.
How would the Bill affect the regulatory regime?
Currently, there are 32 major airports (annual traffic above 15 lakh), and AERA regulates tariffs at 27 of these. As per the Bill, AERA will regulate 16 major airports (annual traffic above 35 lakh). The remaining 16 airports will be regulated by AAI. Till 2030-31, air traffic in the country is expected to grow at an average annual rate of 10-11%. This implies that in a few years, the traffic at the other 16 airports will increase to over 35 lakh and they will again fall under the purview of AERA. This may lead to constant changes in the regulatory regime at these airports. The table below provides the current list of major airports:
