The government has hiked the windfall tax on domestically produced crude oil to ₹6,000 per tonne, from ₹3,250 per tonne, with effect from Tuesday, an increase of 46 per cent.

The tax is levied in the form of Special Additional Excise Duty (SAED).

SAED on the export of diesel, petrol and jet fuel or ATF, has been retained at 'nil'.

The new rates are effective from July 2, an official notification said.

India first imposed windfall profit taxes on July 1, 2022, joining a host of nations that tax supernormal profits of energy companies.

The tax rates are reviewed every fortnight based on average oil prices of the previous two weeks.

Jet fuel or ATF price on Monday was hiked by 1.2 per cent while that of commercial LPG used by hotels and restaurants cut ₹30 per 19-kg cylinder in line with international oil price trends.

Aviation turbine fuel (ATF) price was hiked by ₹1,179.37 per kilolitre, or 1.2 per cent, to ₹96,148.38 per kl in the national capital, according to a price notification of state-owned fuel retailers.

The increase followed a steep 6.5 per cent (₹6,673.87 per kl) reduction effected on June 1.

The ATF rate in Mumbai was increased to ₹89,908.30 per kl from ₹88,834.27.

Prices differ from state to state depending on the incidence of local taxes.

Alongside, oil firms cut the price of commercial LPG by ₹30 to ₹1,646 per 19-kg cylinder.

This is the fourth straight monthly reduction in rates. The price was last cut ₹69 per cylinder on June 1. Prior to that, rates were on May 1 reduced by ₹19 per cylinder, and by ₹30.5 on April 1.

Rate of cooking gas used in domestic households, however, remained unchanged at ₹803 per 14.2-kg cylinder.

Prices of petrol and diesel continue to remain frozen. Rates had been cut by ₹2 per litre in mid-March.
