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.

Discussion on the first no-confidence motion of the 17th Lok Sabha began today.  No-confidence motions and confidence motions are trust votes, used to test or demonstrate the support of Lok Sabha for the government in power.  Article 75(3) of the Constitution states that the government is collectively responsible to Lok Sabha.  This means that the government must always enjoy the support of a majority of the members of Lok Sabha.  Trust votes are used to examine this support.  The government resigns if a majority of members support a no-confidence motion, or reject a confidence motion.  

So far, 28 no-confidence motions (including the one being discussed today) and 11 confidence motions have been discussed.  Over the years, the number of such motions has reduced.  The mid-1960s and mid-1970s saw more no-confidence motions, whereas the 1990s saw more confidence motions.

The no-confidence motion being discussed today was moved on July 26, 2023.  A motion of no-confidence is moved with the support of at least 50 members.   The Speaker has the discretion to allot time for discussion of the motion.  The Rules of Procedure state that the motion must be discussed within 10 days of being introduced.  This year, the no-confidence motion was discussed 13 calendar days after introduction.  Since the introduction of the no-confidence motion on July 26, 12 Bills have been introduced and 18 Bills have been passed by Lok Sabha.  In the past, on four occasions, the discussion on no-confidence motions began seven days after their introduction.  On these occasions, Bills and other important issues were debated before the discussion on the no-confidence motion began.

On average, no-confidence motions (excluding the one being discussed today) have been discussed for 13 hours over three days.  Discussions have lasted longer than 20 hours on four instances, most recently in 2003.  Today’s no-confidence motion was allotted 12 hours discussion time by the Business Advisory Committee.

Following the discussion, the motion is put to vote.  26 out of 27 no-confidence motions (excluding the one being discussed today) have been voted upon and rejected.  This means that no government has ever had to resign following a vote of no-confidence.   On one occasion, in 1979, the discussion on a no-confidence motion against the Morarji Desai government remained inconclusive.  He resigned before the motion was put to vote.  50% of all no-confidence motions (14 out of 28) were discussed between 1965 and 1975.  Of these, 12 were against governments headed by Indira Gandhi.

In comparison, confidence motions have a more varied history.  The first motion, brought in 1979 to demonstrate confidence in Charan Singh’s government, was not discussed at all.  The Prime Minister resigned before the discussion could take place.  Since then, 11 confidence motions have been discussed in Lok Sabha, with nine occurring in the 1990s.  During this period, several coalition governments were formed, and Prime Ministers sought to prove their majority through confidence motions.   These motions have been discussed, on average, for 12 hours over two days.

Of the 11 confidence motions discussed in Lok Sabha, seven were accepted.  On three instances, governments had to resign as they could not prove that they had the support of the majority.  On one instance in 1996, the motion was not put to vote.  Following an eleven-hour discussion on this confidence motion, Prime Minister Atal Bihari Vajpayee announced his intention to resign on the floor of the House.  He resigned 16 days into his term.

Vajpayee became Prime Minister again in 1999, and faced another confidence motion.   This time, it was put to vote.   The motion was defeated by a margin of one vote.  This has been the closest result on a trust vote in the history of Lok Sabha.  The next closest result was when a motion of no-confidence against P V Narasimha Rao’s government was defeated by 14 votes in 1993.  In most cases, results have been in favour of the government by a large margin.
