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.
In November 2017, the 15th Finance Commission (Chair: Mr N. K. Singh) was constituted to give recommendations on the transfer of resources from the centre to states for the five year period between 2020-25. In recent times, there has been some discussion around the role and mandate of the Commission. In this context, we explain the role of the Finance Commission.
What is the Finance Commission?
The Finance Commission is a constitutional body formed every five years to give suggestions on centre-state financial relations. Each Finance Commission is required to make recommendations on: (i) sharing of central taxes with states, (ii) distribution of central grants to states, (iii) measures to improve the finances of states to supplement the resources of panchayats and municipalities, and (iv) any other matter referred to it.
Composition of transfers: The central taxes devolved to states are untied funds, and states can spend them according to their discretion. Over the years, tax devolved to states has constituted over 80% of the total central transfers to states (Figure 1). The centre also provides grants to states and local bodies which must be used for specified purposes. These grants have ranged between 12% to 19% of the total transfers.
Over the years the core mandate of the Commission has remained unchanged, though it has been given the additional responsibility of examining various issues. For instance, the 12th Finance Commission evaluated the fiscal position of states and offered relief to those that enacted their Fiscal Responsibility and Budget Management laws. The 13th and the 14th Finance Commissionassessed the impact of GST on the economy. The 13th Finance Commission also incentivised states to increase forest cover by providing additional grants.
15th Finance Commission: The 15th Finance Commission constituted in November 2017 will recommend central transfers to states. It has also been mandated to: (i) review the impact of the 14th Finance Commission recommendations on the fiscal position of the centre; (ii) review the debt level of the centre and states, and recommend a roadmap; (iii) study the impact of GST on the economy; and (iv) recommend performance-based incentives for states based on their efforts to control population, promote ease of doing business, and control expenditure on populist measures, among others.
Why is there a need for a Finance Commission?
The Indian federal system allows for the division of power and responsibilities between the centre and states. Correspondingly, the taxation powers are also broadly divided between the centre and states (Table 1). State legislatures may devolve some of their taxation powers to local bodies.
The centre collects majority of the tax revenue as it enjoys scale economies in the collection of certain taxes. States have the responsibility of delivering public goods in their areas due to their proximity to local issues and needs.
Sometimes, this leads to states incurring expenditures higher than the revenue generated by them. Further, due to vast regional disparities some states are unable to raise adequate resources as compared to others. To address these imbalances, the Finance Commission recommends the extent of central funds to be shared with states. Prior to 2000, only revenue income tax and union excise duty on certain goods was shared by the centre with states. A Constitution amendment in 2000 allowed for all central taxes to be shared with states.
Several other federal countries, such as Pakistan, Malaysia, and Australia have similar bodies which recommend the manner in which central funds will be shared with states.
Tax devolution to states
The 14th Finance Commission considerably increased the devolution of taxes from the centre to states from 32% to 42%. The Commission had recommended that tax devolution should be the primary source of transfer of funds to states. This would increase the flow of unconditional transfers and give states more flexibility in their spending.
The share in central taxes is distributed among states based on a formula. Previous Finance Commissions have considered various factors to determine the criteria such as the population and income needs of states, their area and infrastructure, etc. Further, the weightage assigned to each criterion has varied with each Finance Commission.
The criteria used by the 11th to 14thFinance Commissions are given in Table 2, along with the weight assigned to them. State level details of the criteria used by the 14th Finance Commission are given in Table 3.
Grants-in-Aid
Besides the taxes devolved to states, another source of transfers from the centre to states is grants-in-aid. As per the recommendations of the 14th Finance Commission, grants-in-aid constitute 12% of the central transfers to states. The 14th Finance Commission had recommended grants to states for three purposes: (i) disaster relief, (ii) local bodies, and (iii) revenue deficit.
