"No one can ignore Odisha's demand. It deserves special category status. It is a genuine right," said Odisha Chief Minister, Naveen Patnaik, earlier this month. The Odisha State assembly has passed a resolution requesting special category status and their demands follow Bihar's recent claim for special category status. The concept of a special category state was first introduced in 1969 when the 5th Finance Commission sought to provide certain disadvantaged states with preferential treatment in the form of central assistance and tax breaks. Initially three states Assam, Nagaland and Jammu & Kashmir were granted special status but since then eight more have been included (Arunachal Pradesh, Himachal Pradesh, Manipur, Meghalaya, Mizoram, Sikkim, Tripura and Uttarakhand). The rationale for special status is that certain states, because of inherent features, have a low resource base and cannot mobilize resources for development. Some of the features required for special status are: (i) hilly and difficult terrain; (ii) low population density or sizeable share of tribal population; (iii) strategic location along borders with neighbouring countries; (iv) economic and infrastructural backwardness; and (v) non-viable nature of state finances. [1. Lok Sabha unstarred question no. 667, 27 Feb, 2013, Ministry of Planning] The decision to grant special category status lies with the National Development Council, composed of the Prime Minster, Union Ministers, Chief Ministers and members of the Planning Commission, who guide and review the work of the Planning Commission. In India, resources can be transferred from the centre to states in many ways (see figure 1). The Finance Commission and the Planning Commission are the two institutions responsible for centre-state financial relations.

Planning Commission and Special Category The Planning Commission allocates funds to states through central assistance for state plans. Central assistance can be broadly split into three components: Normal Central Assistance (NCA), Additional Central Assistance (ACA) and Special Central Assistance. NCA, the main assistance for state plans, is split to favour special category states: the 11 states get 30% of the total assistance while the other states share the remaining 70%. The nature of the assistance also varies for special category states; NCA is split into 90% grants and 10% loans for special category states, while the ratio between grants and loans is 30:70 for other states. For allocation among special category states, there are no explicit criteria for distribution and funds are allocated on the basis of the state's plan size and previous plan expenditures. Allocation between non special category states is determined by the Gadgil Mukherjee formula which gives weight to population (60%), per capita income (25%), fiscal performance (7.5%) and special problems (7.5%). However, as a proportion of total centre-state transfers NCA typically accounts for a relatively small portion (around 5% of total transfers in 2011-12). Special category states also receive specific assistance addressing features like hill areas, tribal sub-plans and border areas. Beyond additional plan resources, special category states can enjoy concessions in excise and customs duties, income tax rates and corporate tax rates as determined by the government. The Planning Commission also allocates funds for ACA (assistance for externally aided projects and other specific project) and funds for Centrally Sponsored Schemes (CSS). State-wise allocation of both ACA and CSS funds are prescribed by the centre. The Finance Commission Planning Commission allocations can be important for states, especially for the functioning of certain schemes, but the most significant centre-state transfer is the distribution of central tax revenues among states. The Finance Commission decides the actual distribution and the current Finance Commission have set aside 32.5% of central tax revenue for states. In 2011-12, this amounted to Rs 2.5 lakh crore (57% of total transfers), making it the largest transfer from the centre to states. In addition, the Finance Commission recommends the principles governing non-plan grants and loans to states. Examples of grants would include funds for disaster relief, maintenance of roads and other state-specific requests. Among states, the distribution of tax revenue and grants is determined through a formula accounting for population (25%), area (10%), fiscal capacity (47.5%) and fiscal discipline (17.5%). Unlike the Planning Commission, the Finance Commission does not distinguish between special and non special category states in its allocation.
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.
