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 Indian Railways announced rationalisation of freight fares. This rationalisation will result in an 8.75% increase in freight rates for major commodities such as coal, iron and steel, iron ore, and raw materials for steel plants. The freight rates were rationalised to ensure additional revenue generation across the network. An additional revenue of Rs 3,344 crore is expected from such rationalisation, which will be utilised to improve passenger amenities. In addition, the haulage charge of containers has been increased by 5% and the freight rates of other small goods have been increased by 8.75%. Freight rates have not been increased for goods such as food grains, flours, pulses, fertilisers, salt, and sugar, cement, petroleum, and diesel. In light of this, we discuss some issues around Railways’ freight pricing.
Railways’ sources of internal revenue
Railways earns its internal revenue primarily from passenger and freight traffic. In 2016-17 (latest actual figures available), freight and passenger traffic contributed to about 63% and 28% of the internal revenue, respectively. The remaining is earned from miscellaneous sources such as parcel service, coaching receipts, and platform tickets.
Freight traffic: Railways majorly transports bulk freight, and the freight basket has mostly been limited to include raw materials for certain industries such as power plants, and iron and steel plants. It generates most of its freight revenue from the transportation of coal (43%), followed by cement (8%), food-grains (7%), and iron and steel (7%). In 2018-19, Railways expects to earn Rs 1,21,950 crore from its freight traffic.
Passenger traffic: Passenger traffic is broadly divided into two categories: suburban and non-suburban traffic. Suburban trains are passenger trains that cover short distances of up to 150 km, and help move passengers within cities and suburbs. Majority of the passenger revenue (94% in 2017-18) comes from the non-suburban traffic (or the long-distance trains).
Within non-suburban traffic, second class (includes sleeper class) contributes to 67% of the non-suburban revenue. AC class (includes AC 3-tier, AC Chair Car and AC sleeper) contributes to 32% of the non-suburban revenue. The remaining 1% comes from AC First Class (includes Executive class and First Class).
Railways’ ability to generate its own revenue has been slowing
The growth rate of Railways’ earnings from its core business of running freight and passenger trains has been declining. This is due to a decline in the growth of both freight and passenger traffic. Some of the reasons for such decline include:
Freight traffic growth has been declining, and is limited to a few items
Growth of freight traffic has been declining over the last few years. It has declined from around 8% in the mid-2000s to a 4% negative growth in mid-2010s, before an estimated recovery to about 5% now.
The National Transport Development Policy Committee (2014) had noted various issues with freight transportation on railways. For example, Indian Railways does not have an institutional arrangement to attract and aggregate traffic of smaller parcel size. Further, freight services are run with a focus on efficiency instead of customer satisfaction. Consequently, it has not been able to capture high potential markets such as FMCGs, hazardous materials, or automobiles and containerised cargo. Most of such freight is transported by roads.
The freight basket is also limited to a few commodities, most of which are bulk in nature. For example, coal contributes to about 43% of freight revenue and 25% of the total internal revenue. Therefore, any shift in transport patterns of any of these bulk commodities could affect Railways’ finances significantly.
For example, if new coal based power plants are set up at pit heads (source of coal), then the need for transporting coal through Railways would decrease. If India’s coal usage decreases due to a shift to more non-renewable sources of energy, it will reduce the amount of coal being transported. Such situations could have a significant adverse impact on Railways’ revenue.
Freight traffic cross-subsidises passenger traffic
In 2014-15, while Railways’ freight business made a profit of about Rs 44,500 crore, its passenger business incurred a net loss of about Rs 33,000 crore.17 The total passenger revenue during this period was Rs 49,000 crore. This implies that losses in the passenger business are about 67% of its revenue. Therefore, in 2014-15, for every one rupee earned in its passenger business, Indian Railways ended up spending Rs 1.67.
These losses occur across both suburban and non-suburban operations, and are primarily caused due to: (i) passenger fares being lower than the costs, and (ii) concessions to various categories of passengers. According to the NITI Aayog (2016), about 77% to 80% of these losses are contributed by non-suburban operations (long-distance trains). Concessions to various categories of passengers contribute to about 4% of these losses, and the remaining (73-76%) is due to fares being lower than the system costs.
The NITI Aayog (2016) had noted that Railways ends up using profits from its freight business to provide for such losses in the passenger segment, and also to manage its overall financial situation. Such cross-subsidisation has resulted in high freight tariffs. The NTDPC (2014) had noted that, in several countries, passenger fares are either higher or almost equal as freight rates. However, in India, the ratio of passenger fare to freight rate is about 0.3.
Impact of increasing freight rates
The recent freight rationalisation further increases the freight rates for certain key commodities by 8.75%, with an intention to improve passenger amenities. Higher freight tariffs could be counter-productive towards growth of traffic in the segment. The NTDPC report had noted that due to such high tariffs, freight traffic has been moving to other modes of transport. Further, the higher cost of freight segment is eventually passed on to the common public in the form of increased costs of electricity, steel, etc. Various experts have recommended that Railways should consider ways to rationalise freight and passenger tariff distortions in a way to reduce such cross-subsidisation.
