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 Lok Sabha has passed the bill to revise the salary of members of parliament. Much of the debate in the media has been on the wealth of current MPs and the lack of accountability. It is important to focus as well on structural issues related to remunerating legislators. Under the bill, the base salary of MPs is being raised to Rs.50,000 from Rs.16,000 per month. The daily allowance paid to MPs when they attend parliament is being hiked to Rs.2,000 from Rs.1,000. The constituency allowance is being increased to Rs.45,000 per month from Rs.20,000 and office expenses (for staff, stationery and postage) to Rs.45,000 per month from Rs.20,000. Pension for former MPs will be Rs.20,000 per month instead of the present Rs.8,000. Other than these, MPs get accommodation in Delhi, which varies from a hostel in Vitthalbhai Patel House to two-bedroom flats and bungalows, all in central Delhi. MPs get reimbursement of electricity, water, telephone and internet charges. They (and their family) are also reimbursed for 34 one-way air tickets from their constituency to Delhi. In a parliamentary democracy, compensation for legislators should be sufficient to ensure their independence and autonomy. It should attract professionals who can devote their full time to legislative work. There should be a sufficient support system to enable legislators perform their duties effectively. There are mainly three issues that need to be resolved while fixing the compensation package for legislators. First, MPs fix their own salaries and allowances, which results in a conflict of interest. Second, every time the salary is revised upwards, there is an adverse media and public reaction. The outcome is that MPs' salaries are significantly lower than that for any other position of similar responsibility in the public or private sector. The low salaries may deter honest persons, without other income sources, from contesting elections. Third, reimbursements of office expenses are classified as 'allowances'. Thus, expenses for office staff, telephone charges, etc. are often seen as part of their compensation. Contrast this with the treatment for government or private sector employees. The costs of office support staff, rental, communication and travel costs are not counted as their salary or perks. The process in India is similar to that in some countries. The US Congress and the German Bundestag determine their own salaries. There are two alternative approaches seen in some other democracies. Some countries appoint an independent authority to determine salaries. Some others peg the salary to that of public officials. For example, New Zealand has a remuneration tribunal which is tasked to fix salaries based on being (a) fair relative to levels of remuneration elsewhere; (b) fair to person being remunerated and the taxpayer; (c) adequate to recruit and retain competent persons. In Canada, a commission is appointed after every general election and salaries are then indexed to the federal government's annual wage rate index. Australia has a remuneration authority that links the salary to that in the Principal Executive Office. In the UK, the Senior Salaries Review Board determines salaries, which are then voted upon by parliament. The Scottish parliament indexes its salaries to that of British MPs. In France, the salary of the legislator is the average of the highest and lowest paid official in the seniormost level of the government. There were two distinct themes during last week's Lok Sabha debate. Several MPs discussed structural issues. Some MPs - L.K. Advani, Ramachandra Dome, Sanjay Nirupam, Shailendra Singh and Pinaki Misra - suggested that the government establish an independent commission for determining salaries. Advani pointed out that a decision to that effect had been taken in an all-party meeting held by the Speaker in may 2005 and demanded that the government announce the formation of such a commission before the end of the current session of parliament. Some MPs - Dhananjay Singh, Sanjay Nirupam and Shailendra Kumar -- focussed on the need for support structures such as office space, research staff and assistants in the constituency. They felt that these would help MPs examine proposed laws and rules and monitor the work of the government. Nirupam and Misra suggested that MPs' salaries be linked to performance; salaries should be cut for any time lost due to disruption. Some MPs highlighted the need for pension and accommodation for former MPs. Sharad Yadav, Raghuvansh Prasad Singh and Sansuma Khunggur Bwiswmuthiary requested that the pension be raised to Rs 25,000 per month. Yadav and Bwiswmuthiary also said that former MPs be allocated residential accommodation in Delhi. The bill will next be discussed in the Rajya Sabha. The government agreed that there is merit in forming an independent commission. It is however uncertain whether the government will accede to Advani's demand that the commission be announced in the next couple of days. - M.R.
