Windfall Tax on Fuel Exports Revised: Petrol Levy Raised, Diesel Levy Cut
The Centre revised the "windfall tax" (an extra tax on unusually high profits) on fuel that Indian refineries export, effective 16 October 2026.
The levy on petrol exports was raised to ₹2.5 per litre from ₹0.5 per litre.
The levy on diesel exports was cut to ₹8.5 per litre from ₹16 per litre.
These export levies were brought in on 27 March 2026, when the West Asia conflict pushed global oil prices up. They aim to keep enough fuel inside India and to let the government share in the extra profits refiners earn abroad.
The rates are reviewed every fortnight (every two weeks), based on average international prices of crude oil, petrol, diesel and ATF (aviation turbine fuel, or jet fuel) since the last review. Taxes on petrol and diesel sold inside India were not changed.
Windfall Tax and Special Additional Excise Duty (SAED)
A windfall tax is an extra tax that a government puts on a company's profits when those profits jump suddenly because of luck, not because of the company's own effort. The word "windfall" comes from fruit that falls from a tree because of the wind: the owner gets it without any work. In India, the windfall tax on oil is collected through a tool called the Special Additional Excise Duty (SAED), a duty charged per litre or per tonne on certain petroleum products.
The 16 October 2026 revision is one more step in the fortnightly cycle that began on 27 March 2026. Margins on petrol exports rose, so the government raised the petrol levy. Diesel margins eased, so the diesel levy was almost halved.
Customs Duty in India: Basic Customs Duty, Cess and the Effective Rate
Customs duty is the tax India charges on goods crossing its borders: mostly imports, but sometimes exports too. It is collected at ports, airports and land check-posts by the Customs department under the Central Board of Indirect Taxes and Customs (CBIC). Parliament gets the power to levy it from Entry 83 of the Union List, which covers "duties of customs including export duties". The main laws are the Customs Act, 1962 (how duty is collected) and the Customs Tariff Act, 1975 (the rates).
News reports call the fuel levy an "export duty", but legally it sits under excise law, not customs law. UPSC can test exactly this difference: which law and which Union List entry each levy comes from.
