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.

Table 1

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.

Effective Sales Tax

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.

Petrol

Diesel

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.

Tax revenue

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 today, the Union Cabinet announced the merger of the Railways Budget with the Union Budget.  All proposals under the Railways Budget will now be a part of the Union Budget.  However, to ensure detailed scrutiny, the Ministry’s expenditure will be discussed in Parliament.  Further, Railways will continue to maintain its autonomy and financial decision making powers.  In light of this, this post discusses some of the ways in which Railways is financed, and issues it faces with regard to financing. Separation of Railways Budget and its financial implications The Railways Budget was separated from the Union Budget in 1924.  While the Union Budget looks at the overall revenue and expenditure of the central government, the Railways Budget looks at the revenue and expenditure of the Ministry of Railways.  At that time, the proportion of Railways Budget was much higher as compared to the Union Budget.  The separation of the Budgets was done to ensure that the central government receives an assured contribution from the Railways revenues.  However, in the last few years, Railways’ finances have deteriorated and it has been struggling to generate enough surplus to invest in improving its infrastructure. Indian Railways is primarily financed through budgetary support from the central government, its own internal resources (freight and passenger revenue, leasing of railway land, etc.), and external resources (market borrowings, public private partnerships, joint ventures, or market financing). Every year, all ministries, except Railways, get support from the central government based on their estimated revenue and expenditure for the year.  The Railways Ministry is provided with a gross budgetary support from the central government in order to expand its network.  However, unlike other Ministries, Railways pays a return on this investment every year, known as dividend.  The rate of this dividend is currently at around 5%, and also includes the interest on government budgetary support received in the previous years. Various Committees have observed that the system of receiving support from the government and then paying back dividend is counter-productive.  It was recommended that the practice of paying dividend can be avoided until the financial health of Railways improves.  In the announcement made today, the requirement to pay dividend to the central government has been removed.  This would save the Ministry from the liability of paying around Rs 9,700 crore as dividend to the central government every year.  However, Railways will continue to get gross budgetary support from the central government. Declining internal revenue In addition to its core business of providing transportation, Railways also has several social obligations such as: (i) providing certain passenger and coaching services at below cost fares, (ii) running uneconomic branch lines (connectivity to remote areas), and (iii) granting concessions to various categories of people (like senior citizens, children, etc.).  All these add up to about Rs 30,000 crore.  Other inelastic expenses of Railways include pension charges, fuel expenses, lease payments, etc.  Such expenses do not leave any financial room for the Railways to make any infrastructure investments. Railways1 In the last few years, Railways has been struggling due to a decline in its revenue from passenger and freight traffic.  In addition, the support from the central government has broadly remained constant. In 2015-16, the gross budgetary support and internal revenue saw a decline, while there was some increase in the extra budgetary resources (shown in Figure 1).   Railways’ internal revenue primarily comes from freight traffic (about 65%), followed by passenger traffic (about 25%).  About one-third of the passenger revenue comes from first class passenger traffic and the remaining two-third comes from second class passenger traffic.  In 2015-16, Railways passenger traffic decreased by 4% and total passenger revenue decreased by 10% from the budget estimates.  While revenue from second class saw a decrease of 13%, revenue from first class traffic decreased by 3%.  In the last few years, Railways’ internal sources have been declining, primarily due to a decline in both passenger as well as freight traffic. Freight traffic Railways2The share of Railways in total freight traffic has declined from 89% to 30% over the last 60 years, with most of the share moving towards roads (see Figure 2).  With regard to freight traffic, Railways generates most of its revenue from the transportation of coal (about 44%), followed by cement (8%), iron ore (7%), and food-grains (7%).  In 2015-16, freight traffic decreased by 10%, and freight earnings reduced by 5% from the budget estimates. The Railways Budget for 2016-17 estimates an increase of 12% in passenger revenue and a 0.26% increase in passenger traffic.  Achieving a 12% increase in revenue without a corresponding increase in traffic will require an increase in fares. Flexi fares and passenger traffic A few days ago, the Ministry of Railways introduced a flexi-fare system for certain categories of trains.  Under this system, the base fare for Rajdhani, Duronto and Shatabdi trains will increase by 10% with every 10% of berths sold, subject to a ceiling of up to 1.5 times the base fare.  While this could also be a way for Railways to improve its revenue, it has raised concerns about train fares becoming more expensive.  Note that the flexi-fare system will apply only to first class passenger traffic, which contributes to about 8% of the total Railways revenue.  It remains to be seen if the new system increases Railways revenue, or further decreases passenger traffic (people choosing other modes of travel, such as airways, if fares increase significantly). While the Railways is trying to improve revenue by raising fares, this may increase the financial burden on passengers.  In the past, various Parliamentary Committees have observed that the investment planning in Railways from the government’s side is politically driven rather than need driven.  This has resulted in the extension of uneconomic, un-remunerative, yet socially desirable projects in every budget.  It has been recommended that projects based on social and commercial considerations must be categorised separately in the Railways accounts, and funding for the former must come from the central or state governments.  It has also been recommended that Railways should bring in more accuracy in determining its public service obligations. The decision to merge the Railways Budget with the Union Budget seems to be on the lines of several of these recommendations.  However, it remains to be seen whether merging the Railway Budget with the Union Budget will  improve the transporter’s finances or if it would require bringing in more reforms.
