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.

The Arms Act, 1959 governs matters related to acquisition, possession, manufacture, sale, transportation, import and export of arms and ammunition. It defines a specific class of ‘prohibited’ arms and ammunitions, restricts their use and prescribes penalties for contravention of its provisions. Section 7 of the Act forbids the manufacture, sale, and use of prohibited arms and ammunition unless it has been specially authorised by the central government.1  Section 27(3) prescribes that any contravention of Section 7 that results in the death of any person 'shall be punishable with death'.2 Section 27(3) of the Act was challenged in the Supreme Court in 2006 in State of Punjab vs. Dalbir Singh.  The final verdict in the case was pronounced last week.  The judgment not only affects the Act in question but may have important implications for criminal law in the country. Legislative history of Section 27 When the law was first enacted, Section 27 provided that possession of any arms or ammunition with intent to use the same for any unlawful purpose shall be punishable with imprisonment up to seven years and/ or a fine. This section was amended in 1988 to provide for enhanced punishments in the context of escalating terrorist and anti-national activities.  In particular, section 27(3) was inserted to provide for mandatory death penalty. The Judgment The Supreme Court judgment says that Section 27(3) is very 'widely worded'.  Any act (including use, acquisition, possession, manufacture or sale) done in contravention of Section 7 that results in death of a person will attract mandatory death penalty.  Thus, even if an accidental or unintentional use results in death, a mandatory death penalty must be imposed. The bench quotes relevant sections of an earlier judgment delivered in 1983, in Mithu vs. State of Punjab.  In this case, the court had looked into the constitutional validity of mandatory death sentence.  The final verdict had ruled that a provision of law which deprives the Court of its discretion, and disregards the circumstances in which the offence was committed, can only be regarded as 'harsh, unjust and unfair'. The judgment goes on to say that the concept of a 'just, fair and reasonable' law has been read into the guarantees under Article 14 (Equality before law) and Article 21 (Protection of life and personal liberty) of the Constitution.  A law that imposes an irreversible penalty such as death is 'repugnant to the concept of right and reason'.  Therefore, Section 27 (3) of the Arms Act, 1959 is unconstitutional. Section 27(3) is also unconstitutional in that it deprives the judiciary from discharging its duty of judicial review by barring it from using the power of discretion in the sentencing procedure. What happens now? Under Article 13 of the Constitution, laws inconsistent with the Constitution shall be null and void.  Therefore, Section 27(3) of the Arms Act, 1959 shall now stand amended.  Courts shall have the discretion to impose a lesser sentence. It is noteworthy that the Home Minister had also introduced a Bill in the Lok Sabha on the 12th of December, 2011 to amend the Arms Act, 1959.  The Bill seeks to remove the words ‘shall be punishable with death’ and replace these with ‘shall be punishable with death or imprisonment for life and shall also be liable to fine’.  This Bill is currently being scrutinized by the Standing Committee. Notes: 1) Section 7 of the Arms Act, 1959: “7. Prohibition of acquisition or possession, or of manufacture or sale, of prohibited arms or prohibited ammunition.  No person shall -- (a) acquire, have in his possession or carry; or (b) use, manufacture, sell, transfer, convert, repair, test or prove; or (c) expose or offer for sale or transfer or have in his possession for sale, transfer, conversion, repair, test or proof; any prohibited  arms  or  prohibited ammunition unless he has been specially authorised by the Central Government in this behalf.” 2) Section 27(3) of the Arms Act, 1959: “27(3) Whoever uses any prohibited arms or prohibited ammunition or does any act in contravention of section 7 and such use or act results in the death of any other person, shall be punishable with death.” Sources: Arms Act, 1959;  Supreme Court judgment
