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.

Table 1

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.

Effective Sales Tax

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.

Petrol

Diesel

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.

Tax revenue

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.

Today, a general discussion on the Union Budget 2020-21 is being held in both Houses of Parliament.  In the budget, the government presented the estimates of the money it expects to spend on various ministries, and how much money will be raised from different sources such as levy of taxes and dividends from public enterprises in 2020-21.  In addition, the budget presented the revised estimates made by the government for the year 2019-20 in comparison to the estimates it had given to Parliament in the previous year’s budget.  The budget also gave an account of how much money the government actually raised and spent in 2018-19.  

What are revised estimates?

Some of the estimates made by the government might change during the course of the year.  For instance, once the year gets underway, some ministries may need more funds than what was actually allocated to them in the budget, or the receipts expected from certain sources might change.  Such deviations from the budget estimates get reflected in the figures released by the government at later stages as part of the subsequent budgets.  Once the year ends, the actual numbers are audited by the Comptroller and Auditor General of India (CAG), post which they are presented to Parliament with the upcoming budget, i.e. two years after the estimates are made.

For instance, estimates for the year 2019-20 were presented as part of the 2019-20 budget in July 2019.  In the 2020-21 budget (February 2020), the government presented 2019-20’s revised estimates based on the actual receipts and expenditure accounted so far during the year and estimations made for the remaining 2-3 months.

Is there a way to find out the government’s actual receipts or expenditure mid-year?

The actual receipts and expenditure accounts of the central government are maintained by the Controller General of Accounts (CGA), Ministry of Finance on a monthly basis.  On January 31, 2020, the CGA updated the accounts figures for the period April to December 2019.  Thus, we have unaudited actuals for the first nine months of the financial year.

How do the actual figures for the year 2019-20 so far compare with the revised estimates?

Table 1 gives the revised estimates presented by the central government for the year 2019-20 and the monthly account figures maintained by the CGA for the nine-month period April to December 2019.  The difference between these two figures gives us the three-month target that the government will have to meet by March 2020 to reach its revised estimates.    

Till December 2019, the government has spent Rs 21.1 lakh crore, which is 78% of the revised estimates for 2019-20.  While the expenditure has reached 78% of the target, so far, the government has been able to generate only Rs 11.8 lakh crore or 61% of the receipts (excluding borrowings) for the year 2019-20.  This implies that the receipts will have to grow at a rate of 41% in the three-month period January-March 2020 to meet the revised estimates of Rs 19.3 lakh crore.   So far, receipts have grown at a rate of 4%.

How do the actual tax receipts fare in comparison to the revised estimates of 2019-20?

A lower than estimated growth in nominal GDP has also affected the tax receipts of the government during the year. The 2019-20 budget estimated the nominal GDP to grow at 12% over the previous year, whereas the latest estimates suggest this growth rate to be 7.5% in 2019-20.  The revised estimates for 2019-20 show gross tax receipts of Rs 21.6 lakh crore (includes states’ share).  Till December 2019, tax receipts of Rs 13.8 lakh crore has been collected, which is 64% of the target.  The tax receipts will have to grow at 19% in the three-month period January-March 2020 to meet the target.  Table 2 shows similar comparison for the various taxes and also for the tax receipts devolved to states.  While the budget estimated a growth in receipts from all major taxes, receipts from taxes such as corporation tax (-14%), union excise duties (-2%), and customs (-12%) have declined during the period Apr-Dec 2019.

If we look at sources of receipts other than taxes, non-tax revenue during Apr-Dec 2019 is Rs 2.4 lakh crore, i.e. 69% of the estimated Rs 3.5 lakh crore.  Disinvestment receipts till date amounted to Rs 18,100 crore, i.e. 17% of the budget target of Rs 1.05 lakh crore.  Though the investment target has been revised down to Rs 65,000 crore, it implies that Rs 47,000 crore would need to be raised in the next two months.    

How does this impact the borrowings of the government?

When the expenditure planned by the government is more than its receipts, the government finances this gap through borrowings.  This gap is known as fiscal deficit and equals the borrowings required to be made for that year.  Given lower than expected receipts, the government has had to borrow more money than it had planned for.  Borrowings or fiscal deficit of the government, till December 2019, stands at Rs 9.3 lakh crore, which is 22% higher than the revised estimate of Rs 7.7 lakh crore.  Note that with three months still remaining in the financial year, fiscal deficit may further increase, in case receipts are less than expenditure.

When we look at fiscal deficit as a percentage of GDP, the 2019-20 budget estimated the fiscal deficit to be at 3.3% of GDP.  This has been revised upward to 3.8% of GDP.  However, till December 2019, fiscal deficit for the year 2019-20 stands at 4.6% of GDP (taking the latest available GDP figures into account, i.e. the First Advance Estimates for 2019-20 released in January 2020).  This increase in fiscal deficit as a percentage of GDP is because of two reasons: (i) an increase in borrowings as compared to the budget estimates, and (ii) a decrease in GDP as compared to the estimate made in the budget.  The latter is due to a lower than estimated growth in nominal GDP for the year 2019-20.   The 2019-20 budget estimated the nominal GDP to grow at 12% over the previous year, whereas the latest estimates suggest this growth rate to be 7.5% in 2019-20.

Note that, in addition to the expenditure shown in the budget, the government also spends through extra budgetary resources. These resources are raised by issuing bonds and through loans from the National Small Savings Fund (NSSF).  The revised estimates for 2019-20 show an expenditure of Rs 1,72,699 crore through such extra-budgetary resources. This includes an expenditure of Rs 1,10,000 crore by the Food Corporation of India financed through loans from NSSF. Since funds borrowed for such expenditure remain outside the budget, they do not get factored in the deficit and debt figures.  If borrowings made in the form of extra-budgetary resources are also taken into account, the fiscal deficit estimated for the year 2019-20 would increase from 3.8% of GDP to 4.6% of GDP due to extra-budgetary borrowings of Rs 1,72,699 crore.  This does not account for further slippage if the targeted revenue does not materialise.
