‘AD VALOREM' TAX BASIS

The taxes on petroleum products are largely ‘ad valorem' taxes — i.e. tax is based on the value of the product such as 27 per cent VAT on petrol and 21.43 per cent on diesel by the Tamil Nadu Government. Thus, when the price of diesel is revised by Rs 1 by the oil marketing companies, VAT on diesel gets revised upwards automatically. Similarly, customs duty on imports and road development cess are also levied on ad valorem basis. This results in a cascading effect on any increase in the basic price, thereby fuelling inflation. A better, and more transparent, way of taxation is specific duty i.e. say VAT of Rs 14 per litre. This way, any revision of this rate is the responsibility of the respective state government, and they can no longer get a free ride based on the oil companies' price revisions.

INCIDENCE OF TAXES

The two main petroleum products, viz. petrol and diesel, suffer from high incidence of overall taxes. A barrel of crude (160 litres of crude) produces approximately 150 litres of diesel/petrol/ATF equivalent. At $100 per barrel of oil, and additional $12 towards cost of refining, transportation of crude and finished goods, the final ‘price at the fuelling station' without any taxes will be Rs 38 per litre (112x51/150) for both diesel and petrol. Against this, the selling price of Rs 44 for diesel and Rs 67 for petrol implies total tax incidence of 16 per cent and 76 per cent, respectively. One key point to note here is, shorn of taxes at various levels, diesel isn't subsidised at current rates; it may earn lesser tax revenue to the government compared to petrol or ATF, but calling it “subsidised” is a travesty. While taxation on petroleum products is a public policy debate, and altering this may have serious implications on the fiscal health of state and central governments, fixing the taxes at specific rates at current levels could, during a period of time, reduce the impact of taxation, as the basic price increases gradually.

MINIMAL GOVT INTERFERENCE

Reforming the petroleum sector by allowing free pricing of petroleum products by oil companies based on international prices, and achieving social goals, such as subsidising kerosene or LPG through transparent specific duty on petrol, ATF and diesel would significantly improve the health of the petroleum sector. The Government can adopt a stance similar to the RBI's stated policy on forex rates — intervention only to prevent excess volatility, but not in any directional movement — for petroleum product pricing, minimising political fall out of price revisions.
