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.
The issue of the General Anti Avoidance Rule (GAAR) has dominated the news recently and there are fears that GAAR will discourage foreign investment in India. However, tax avoidance can hinder public finance objectives and it is in this context GAAR was introduced in this year’s Budget. Last week, the Finance Minister pushed back the implementation of GAAR by a year. What is GAAR? GAAR was first introduced in the Direct Taxes Code Bill 2010. The original proposal gave the Commissioner of Income Tax the authority to declare any arrangement or transaction by a taxpayer as ‘impermissible’ if he believed the main purpose of the arrangement was to obtain a tax benefit. The 2012-13 Finance Bill (Bill), that was passed by Parliament yesterday, defines ‘impermissible avoidance arrangements’ as an arrangement that satisfies one of four tests. Under these tests, an agreement would be an ‘impermissible avoidance arrangement’ if it (i) creates rights and obligations not normally created between parties dealing at arm’s length, (ii) results in misuse or abuse of provisions of tax laws, (iii) is carried out in a way not normally employed for bona fide purpose or (iv) lacks commercial substance. As per the Bill, arrangements which lack commercial substance could involve round trip financing, an accommodating party and elements that have the effect of offsetting or cancelling each other. A transaction that disguises the value, location, source, ownership or control of funds would also be deemed to lack commercial substance. The Bill as introduced also presumed that obtaining a tax benefit was the main purpose of an arrangement unless the taxpayer could prove otherwise. Why? GAAR was introduced to address tax avoidance and ensure that those in different tax brackets are taxed the correct amount. In many instances of tax avoidance, arrangements may take place with the sole intention of gaining a tax advantage while complying with the law. This is when the doctrine of ‘substance over form’ may apply. ‘Substance over form’ is where real intention of parties and the purpose of an arrangement is taken into account rather than just the nomenclature of the arrangement. Many countries, like Canada and South Africa, have codified the doctrine of ‘substance over form’ through a GAAR – type ruling. Issues with GAAR A common criticism of GAAR is that it provides discretion and authority to the tax administration which can be misused. The Standing Committee responded to GAAR in their report on the Direct Taxes Code Bill in March, 2012. They suggested that the provisions should ensure that taxpayers entering genuinely valid arrangements are not harassed. They recommended that the onus should be on tax authorities, not the taxpayer, to prove tax avoidance. In addition, the committee suggested an independent body to act as the approving panel to ensure impartiality. They also recommended that the assessing officer be designated in the code to reduce harassment and unwarranted litigation. GAAR Amendments On May 8, 2012 the Finance Minister amended the GAAR provisions following the Standing Committee’s recommendations. The main change was to delay the implementation of GAAR by a year to “provide more time to both taxpayers and the tax administration to address all related issues”. GAAR will now apply on income earned in 2013-14 and thereafter. In addition, the Finance Minister removed the burden upon the taxpayer to prove that the main purpose of an alleged impermissible arrangement was not to obtain tax benefit. These amendments were approved with the passing of the Bill. In his speech, the Finance Minister stated that a Committee had also been formed under the Chairmanship of the Director General of Income Tax. The Committee will suggest rules, guidelines and safeguards for implementation of GAAR. The Committee is expected to submit its recommendations by May 31, 2012 after holding discussions with various stakeholders in the debate.
