The windfall tax on diesel has been slashed to Rs 0.5 per litre from Rs 1 per litre earlier.
There is no windfall tax on petroleum, jet fuel, or aviation turbine fuel (ATF).
Windfall tax is levied by the government on unexpectedly high profits companies earn.
It was levied in July 2022 as high energy prices had led to high profits for oil producers.
Since then, windfall taxes for crude oil have declined from Rs 23,250 per tonne in July 2022 to Rs 3,500 per tonne as of March 21.
