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.

In law, the addition or deletion a single punctuation or a single word can have a major impact on the effect of that law.  One such example can be seen from the recommended changes in the Civil Liability for Nuclear Damage Bill, 2010 by Parliament’s Standing Committee. The Civil Liability for Nuclear Damage Bill, 2010 was introduced in the Lok Sabha on May 7, 2010.  The Bill was referred to the Parliamentary Committee on Science and Technology, Environment and Forests, which submitted its report on the Bill yesterday (August 18, 2010).  The Committee has made a number of recommendations regarding certain clauses in the Bill (See summary here).  One of these may have the effect of diluting the provision currently in the Bill.  The main recommendations pertain to:

  • Preventing the entry of private operators.
  • Allowing the government to increase the total liability for a nuclear incident by notification, but not decrease it.
  • Increasing the liability of the operator to Rs 1,500 crore from Rs 500 crore.
  • Increasing the time limit for claiming compensation to 20 years from 10 years.
  • Changing the provision giving operators a right of recourse against persons actually responsible for causing damage.

Clause 17 of the Bill which gives operators a right of recourse against those actually causing damage had been opposed as it was felt that it was not strong enough to hold suppliers liable in case the damage was caused by them.  Clause 17 gave a right of recourse under three conditions.  The exact clause is reproduced below: The operator of a nuclear installation shall have a right of recourse where — (a) such right is expressly provided for in a contract in writing; (b) the nuclear incident has resulted from the wilful act or gross negligence on the part of the supplier of the material, equipment or services, or of his employee; (c) the nuclear incident has resulted from the act of commission or omission of a person done with the intent to cause nuclear damage. Under this clause, a right of recourse exists when (a) there is a contract giving such a right, or (b) the supplier acts deliberately or in a grossly negligent manner to cause nuclear damage, or (c) a person causes nuclear damage with the intent to do so.  If any of the three cases can be proved by the operator, he has a right of recourse. The Committee has stated that “Clause 17(b) gives escape route to the suppliers of nuclear materials, equipments, services of his employees as their willful act or gross negligence would be difficult to establish in a civil nuclear compensation case.” It recommended that Clause 17(b) should be modified to cover consequences “of latent or patent defect, supply of sub-standard material, defective equipment or services or from the gross negligence on the part of the supplier of the material, equipment or service.” The Committee also recommended another change in Clause 17.  It recommended that clause 17(a) may end with “and”. This provision may dilute the right of recourse available to operators.  The modified clause 17 would read as: The operator of a nuclear installation shall have a right of recourse where — (a) such right is expressly provided for in a contract in writing; and, (b) the nuclear incident has resulted as a consequence of latent or patent defect, supply of sub-standard material, defective equipment or services or from the gross negligence on the part of the supplier of the material, equipment or services.; (c) the nuclear incident has resulted from the act of commission or omission of a person done with the intent to cause nuclear damage. This implies that for Clauses 17(b) or (c) to be applicable, the condition specified in clause 17(a) has to be compulsorily satisfied.  Two examples highlight the consequence of the recommended change in Clause 17(a) of the Bill:

  1. A person X deliberately commits sabotage in a nuclear plant and causes damage.  Under the Bill, the operator has recourse under Clause 17(c).  If the recommendation regarding clause 17 is accepted, the operator may also have to also prove the existence of a pre-existing contract with X in addition to clause 17(c).
  2. If a supplier supplies defective equipment, but does not have a contract in writing stating that he will be liable for damage caused by defective equipment, the operator may not have a right of recourse against the supplier under 17(b).

The effect of the changes recommended by the committee may thus dilute the provision as it exists in the Bill.  The table below compares the position in the Bill and the position as per the Standing Committee’s recommendations:

Right of recourse - The Bill gives operators a right to recourse under three conditions:  (a) if there is a clear contract; (b) if the damage is caused by someone with intent to cause damage; (c) against suppliers if damage is caused by their wilful act or negligence. In the Bill the three conditions are separated by a semi-colon.  The Committee recommended that the semi-colon in clause 17(a) should be replaced by “and”. This might imply that all three conditions mentioned need to exist for an operator to have recourse.
Right to recourse against suppliers exists in cases of “willful act or gross negligence on the part of the supplier”. (Clause 17) The Committee felt that the right of recourse against suppliers is vague.  It recommended that recourse against the supplier should be strengthened.  The supplier is liable if an incident has occurred due to (i) defects, or (ii) sub-standard material, or (iii) gross negligence of the supplier of the material, equipment or services. The variance with the Convention continues to exist.
