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.
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.
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.
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.
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.
Yesterday, the government circulated certain official amendments to the Constitution (122nd Amendment) Bill, 2014 on GST. The Bill is currently pending in Rajya Sabha. The Bill was introduced and passed in Lok Sabha in May 2015. It was then referred to a Select Committee of Rajya Sabha which submitted its report in July 2015. With the Bill listed for passage this week, we explain key provisions in the Bill, and the amendments proposed. What is the GST? Currently, indirect taxes are imposed on goods and services. These include excise duty, sales tax, service tax, octroi, customs duty etc. Some of these taxes are levied by the centre and some by the states. For taxes imposed by states, the tax rates may vary across different states. Also, goods and services are taxed differently. The Goods and Services Tax (GST) is a value added tax levied across goods and services at the point of consumption. The idea of a GST regime is to subsume most indirect taxes under a single taxation regime. This is expected to help broaden the tax base, increase tax compliance, and reduce economic distortions caused by inter-state variations in taxes. What does the 2014 Bill on GST do? The 2014 Bill amends the Constitution to give concurrent powers to Parliament and state legislatures to levy a Goods and Services tax (GST). This implies that the centre will levy a central GST (CGST), while states will be permitted to levy a state GST (SGST). For goods and services that pass through several states, or imports, the centre will levy another tax, the Integrated GST (IGST). Alcohol for human consumption has been kept out of the purview of GST. Further, GST will be levied on 5 types of petroleum products at a later date, to be decided by the GST Council. The Council is a body comprising of Finance Ministers of the centre and all states (including Delhi and Puducherry). This body will make recommendations in relation to the implementation of GST, including the rates, principles of levy, etc. The Council is also to decide the modalities for resolution of disputes that arise out of its recommendations. States may be given compensation for any revenue losses they may face from the introduction of the GST regime. Such compensation may be provided for a period of up to five years. Further, the centre may levy an additional tax, up to 1%, in the course of interstate trade. The revenues from the levy of this tax will be given to the state from where the good originates. Expert bodies like the Select Committee and the Arvind Subramanian Committee have observed that this provision could lead to cascading of taxes (as tax on tax will be levied).[i] It also distorts the creation of a national market, as a product made in one state and sold in another would be more expensive than one made and sold within the same state. What are the key changes proposed by the 2016 amendments? The amendments propose three key changes to the 2014 Bill. They relate to (i) additional tax up to 1%; (ii) compensation to states; and (iii) dispute resolution by the GST Council.
These amendments will be taken up for discussion with the Bill in Rajya Sabha this week. The Bill requires a special majority for its passage as it is a Constitution Amendment Bill (that is at least 50% majority of the total membership in the House, and 2/3rds majority of all members present and voting). If the Bill is passed with amendments, it will have to be sent back to Lok Sabha for consideration and passage. After its passage in Parliament, at least 50% state legislatures will have to pass resolutions to ratify the Bill. Once the constitutional framework is in place, the centre will have to pass simple laws to levy CGST and IGST. Similarly, all states will have to pass a simple law on SGST. These laws will specify the rates of the GST to be levied, the goods and services that will be included, the threshold of the turnover of businesses to be included, etc. Note that the Arvind Subramanian Committee, set up by the Finance Ministry, recommended the rates of GST that may be levied. The table below details the bands of rates proposed.
| Table 1: Rates of GST recommended by Expert Committee headed by Arvind Subramanian | ||
| Type of rate | Rate | Details |
| Revenue Neutral Rate | 15% | Single rate which maintains revenue at current levels. |
| Standard Rate | 17-18% | Too be applied to most goods and services |
| Lower rates | 12% | To be applied to certain goods consumed by the poor |
| Demerit rate | 40% | To be applied on luxury cars, aerated beverages, paan masala, and tobacco |

Several other measures related to the back end infrastructure for registration and reporting of GST, administrative officials related to GST, etc. will also have to be put in place, before GST can be rolled out.
