In the past few months, retail prices of petrol and diesel have consistently increased to all-time high levels.  On October 16, 2021, the retail price of petrol in Delhi was Rs 105.5 per litre, and that of diesel was Rs 94.2 per litre.  In Mumbai, these prices were even higher at Rs 111.7 per litre and Rs 102.5 per litre, respectively.

The difference in fuel retail prices in the two cities is due to the different tax rates levied by the respective state governments on the same products.  In this blog post, we look at the tax components in the price structure of petrol and diesel, the variation in these across states, and the major changes in taxation of these products in the recent years.  We also discuss changes in the retail prices over the past few years and how it compares vis-à-vis the global crude oil prices.

Taxes make up around 50% of the retail price

Public sector Oil Marketing Companies (OMCs) revise the retail prices of petrol and diesel in India on a daily basis, according to changes in the price of global crude oil.  The price charged to dealers includes the base price set by OMCs and the freight price.   As on October 16, 2021, the price charged to dealers makes up 42% of the retail price in the case of petrol, and 49% of the retail price in the case of diesel (Table 1).

The break-up of retail prices of petrol and diesel in Delhi (as on October 16, 2021), shows that around 54% of the retail price of petrol comprises central and states taxes.  In the case of diesel, this is close to 49%.  The central government taxes the production of petroleum products, while states tax their sale.  The central government levies an excise duty of Rs 32.9 per litre on petrol and Rs 31.8 per litre on diesel.  These make up 31% and 34% of the current retail prices of petrol and diesel, respectively.

While excise duty rates are uniform across the country, states levy sales tax/ Value Added Tax (VAT) which varies across states.  For instance, Odisha levies 32% VAT on petrol, while Uttar Pradesh levies 26.8% VAT or Rs 18.74 per litre, whichever is higher.   Refer to the table 3 in annexure for sales taxes/VAT levied across the country.  The figure below shows the different tax rates levied by states on petrol and diesel.  In addition to the tax rates shown in the graph, many state governments, such as Tamil Nadu, also levy certain additional levies such as cess (Rs 11.5 per litre).

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 value of excise duty component of the price structure is fixed, the value of the sales tax component is dependent on the other three components, i.e., price charged to dealers, dealer commission, and excise duty.

Retail prices in India compared to 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 of petroleum products were 69% of the total consumption, which increased to around 95% in 2020-21.  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 two figures below show the trend in the price of global crude oil and retail prices of petrol and diesel in India, over the last nine years.

Between June 2014 and October 2018, the retail selling prices did not adhere to change in global crude oil prices.  The global prices fell sharply between June 2014 and January 2016, and then subsequently increased between February 2016 and October 2018.  However, the retail selling prices remained stable during the entire period.  This disparity in the change in global and Indian retail prices was because of the subsequent changes in taxes.  For instance, central taxes were increased by Rs 11 and 13 between June 2014 and January 2016 on petrol and diesel respectively.  Subsequently, taxes were decreased by four rupees between February 2016 and October 2018 for petrol and diesel.  Similarly, during January-April 2020, following a sharp decline of 69% in the global crude oil prices, the central government increased the excise duty on petrol and diesel by Rs 10 per litre and Rs 13 per litre, respectively in May 2020. 

Sharp increase in excise duty collections

As a result of the increase in excise duty in May 2020, the excise duty collection increased sharply from Rs 2.38 lakh crore in 2019-20 to Rs 3.84 lakh crore in 2020-21.  The year-on-year growth rate of excise duty collection increased from 4% in 2019-20 to 67% in 2020-21.  However, sales tax collections (from petroleum products) during that period remained more or less constant (Figure 3).

Share of states in excise duty has decreased over the years

Though central taxes (such as excise duty) are levied by the centre, it has only 59% of the revenue from these taxes.  The remaining 41% of the revenue is required to be devolved to the state governments as per the recommendations of the 15^th Finance Commission.  These devolved taxes are un-tied in nature, states can spend them according to their own discretion.  The excise duty levied on petrol and diesel consists of two broad components: (i) tax component (i.e., basic excise duty), and (ii) cess and surcharge component.  Of this, only the revenue generated from the tax component is devolved to states.  Revenue generated by the centre from any cess or surcharge is not devolved to states.  Currently, the Agriculture Infrastructure and Development Cess, and the Road and Infrastructure Cess are levied on the sale of petrol and diesel in addition to the surcharge.  

In the Union Budget 2021-22, the Agriculture Infrastructure and Development cess on petrol and diesel was announced at Rs 2.5 per litre and Rs 4 per litre, respectively.  However, simultaneously, the basic excise duty and surcharge were reduced by equal amounts, so that the overall rate remains the same.  Essentially, this provision shifted a revenue of Rs 1.5 per litre of petrol and Rs 3 per litre of diesel from the states’ divisible pool of taxes to the cess and surcharge revenue, which is entirely with the centre.  Similarly, over the last four years, the share of tax component in the excise duty has decreased by 40% in petrol and 59% in diesel (table 2).  At present, majority of the excise duty levied on petrol (96%) and diesel (94%) is in the form of cess and surcharge, due to which it is entirely under the centre’s share (Table 2).

As a result, the devolution to states out of the excise duty has declined over the last four years.   Even though the excise duty collections have increased sharply between 2019-20 and 2020-21, the devolved component has declined from Rs 26,464 to Rs 19,578 (revised estimate) in the same period.
