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.

Parliament is expected to take up a motion for impeaching Justice Soumitra Sen of the Calcutta High Court.  We wrote an FAQ on the process of impeachment and the facts of this case for Rediff. See: http://www.rediff.com/news/report/faq-on-impeachment-of-judges/20110816.htm The full text is reproduced below. What is the importance of Parliament's discussion on the Justice Sen issue? The Rajya Sabha is scheduled to discuss a motion for the removal of Justice Soumitra Sen of the Calcutta High Court.  Till date, no judge of the higher judiciary (Supreme Court and High Courts) has been successfully impeached. What is the legal framework regarding impeachment of judges? The Constitution has measures to ensure the independence of the judiciary from executive action.  This helps judges give judicial decisions in a free and fair manner without any inducements. The Constitution also provides checks against misbehaviour by judges.  It states that a judge may be removed only through a motion in Parliament with a two thirds support in each House.  The process is laid down in the Judges (Inquiry) Act, 1968. How is the motion initiated?  What is the process after that? A motion has to be moved by either 100 Lok Sabha members of Parliament or 50 Rajya Sabha MPs.  If the motion is admitted, the Speaker of Lok Sabha or Chairman of Rajya Sabha constitutes an inquiry committee. The committee has three members: a Supreme Court judge, a High Court Chief Justice, and an eminent jurist.  The Committee frames charges and asks the judge to give a written response. The judge also has the right to examine witnesses.  After the inquiry, the committee determines whether the charges are valid or not.  It then submits its report. What happens then? If the inquiry committee finds that the judge is not guilty, then there is no further action.  If they find him guilty, then the House of Parliament which initiated the motion may consider continuing with the motion. The motion is debated.  The judge (or his representative) has the right to represent his case.  After that, the motion is voted upon.  If there is two-thirds support of those voting, and majority support of the total strength of the House, it is considered to have passed.  The process is then repeated in the other House. After that, the Houses send an address to the President asking that the judge be removed from office. Has this process taken place earlier? Yes, there has been one such case.  Justice Ramaswamy of the Supreme Court faced such a motion.  The inquiry committee found that the charges against him were valid.  However, the motion to impeach him did not gather the required support in Lok Sabha. What are the charges against the Justice Sen? There are two charges.  He is accused of misappropriating large sums of money which he received as a receiver appointed by the Calcutta High Court.  He is also accused of misrepresenting facts in this regard to the High Court. What is the charge of misappropriation?  What did the inquiry committee conclude? Justice Soumitra Sen was appointed Receiver in a case by an order of the Calcutta High Court on April 30, 1984. As a Receiver, Justice Sen had the power to collect outstanding debts and claims due in respect of certain goods. The Receiver is required to file and submit for passing, his half yearly accounts in the Office of the Registrar of the High Court.  However, Justice Sen did not comply with this rule.  As a Receiver, Justice Sen was required to open only one account and not move funds without prior permission. However, the Inquiry Committee found that two separate accounts were opened by Justice Soumitra Sen as Receiver, with ANZ Grindlays Bank and Allahabad Bank.  A total sum of over Rs 33 lakh was transferred in these accounts from the sale of the goods which was unaccounted for. Justice Sen claimed he could not account for this amount since it was invested in a company called Lynx India Ltd. to earn interest. The Inquiry Committee found this claim to be false as well. It was found that the amount transferred to Lynx India Ltd. had been made out of an account opened by Justice Sen in his own name.  The Committee concluded that (a) there was a large-scale diversion of fund, and (b) such diversion was in violation of the orders of the High Court. The purpose for such diversion remains unexplained. This action was done by him as an advocate? Are there any charges against him after he was appointed as a judge? Justice Soumitra Sen was appointed a High Court Judge on December 3, 2003. The Inquiry Committee noted that Justice Sen's actions were, "an attempt to cover up the large-scale defalcations of Receiver's funds". After he became a Judge he did not seek any permission from the Court for approval of the dealings, as required by the Court, nor did he account for the funds. Is there any other case?  What is the status? Another such motion has been initiated against Chief Justice Dinakaran of Sikkim High Court.  An Inquiry Committee is looking investigating the issue.  However, Mr Dinakaran has reportedly sent in his resignation to the President.  If the resignation is accepted, then the motion to remove him will become ineffective.
