Whenever global events result in an unprecedented surge in profits of an industry, then the government steps in to claim a share of the profit by taxing the profit. This concept is known as windfall tax.
India had imposed windfall tax from 2022 to 2024, and then again in March 2026 when due to the Iran-US conflict. Let us explore what windfall tax is, which conditions lead to the windfall tax being imposed, history of Windfall tax in India, and the current revision as of June 2026.

What Is a Windfall Tax?
A windfall tax is a tax levied by a government on an industry making unexpected, excessive profits. The reason for these profits is not that they are better managed or have a smarter business strategy. They are the result of unforeseen external shocks, like wars, supply shocks or geopolitical problems, which the companies did not cause.
According to the United States Congressional Research Service, a windfall is an unexpected increase in income or earnings that is received without any additional effort or cost, Windfall taxes are taxes levied by governments to seize a share of the windfall and allocate it to public needs.
The most common targets are industries in the energy sector. When oil and gas prices rise, oil and gas companies can see profits grow like wildfire, as their input costs do not increase as quickly as their selling prices.
Why Do Governments Impose Windfall Taxes?
There are three primary functions of imposing windfall taxes which are as follows:
Firstly, they can be used to generate revenue for the government in a crisis. The additional money can be used to offset inflation, to provide subsidies to consumers for fuel, or to finance budget deficits resulting from the same shock.
Second, they tackle the issues of fairness. A geopolitical shock can yield huge gains for a company, making it hard to justify for many citizens and policymakers. A windfall tax narrows the difference between the unearned gain of the company and the burden on the public.
Third, they provide a means for the Government to ensure that important sectors continue to provide for the domestic market. This was the strategy that India applied directly. While there was a shortage in the domestic market, private refiners were exporting fuel to earn better margins. An export tax brought back the incentive in favor of home supply.
The primary objection is that windfall taxes introduce uncertainty into the markets. The fear of taxing future profits when prices unexpectedly increase can cause companies to be hesitant to invest in long-term production.
India's Windfall Tax: Timeline
First Introduced in 2022
The windfall tax was implemented in India from 1st July 2022. The impetus was Russia's invasion of Ukraine in February 2022. The war affected the supply of oil in the world and caused the price of crude oil to exceed 100 US dollars per barrel.
The profits of Indian oil companies, especially ONGC, Oil India and Vedanta's Cairn Oil and Gas, jumped significantly. Private refiners, such as Reliance Industries and Nayara Energy, made high margins from exporting petrol, diesel and ATF to the international market.
The government imposed the levy in the form of Special Additional Excise Duty (SAED). The domestic crude oil rate at the time of launch was of Rs. 23,250 per tonne. The export taxes on diesel, petrol and ATF were implemented simultaneously.
The windfall tax imposed in India had a unique provision that it was revised every fortnight. Rates have been checked every 15 days, according to the average international crude oil rates for the last two weeks. The tax rate was reduced when the price of the product dropped in the world market. The rate increased as they rose.
This made the tax dynamic and responsive, unlike most fixed-rate levies. The government revised rates over 20 times between July 2022 and December 2024.
Levy on ATF and petrol exports was phased out, as refining margins eased. The government has lowered the windfall tax on domestic crude oil to zero per tonne by September 18, 2024. In reality, this put an end to the levy long before its official expiration date.
India Abolishes the Windfall Tax (December 2024)
The Indian government formally abolished the windfall tax on December 2, 2024. The announcement came through CBIC Notification 29/2024, tabled by Union Minister of State for Finance Pankaj Chaudhary in Parliament.
The abolition covered all remaining levies: domestic crude oil production and exports of diesel, petrol, and ATF. The government also scrapped the Road and Infrastructure Cess (RIC) on petrol and diesel exports at the same time.
Three factors led to the decision:
1. Global crude oil prices had stabilised after the 2022 peak and hence wasn’t generating any profit.
2. Due to stabilisation of price, the windfall tax rate was reduced to zero on crude oil since September 2024, thereby making the announcement a matter of time.
3. Oil companies and industry bodies argued that the tax levied on exports hurt higher production levels and long term investment decisions.
The abolition provided direct relief to ONGC, Oil India, Reliance Industries, Vedanta, and Nayara Energy.
Windfall Tax Reimposed Due to West Asia Crisis in 2026
The windfall-free period in India was less than 16 months. In 2026, as the situation in West Asia deteriorated, crude oil prices in the world shot up again, and private refiners started to export fuel rather than supply local markets. In response, the government re-imposed the windfall tax on March 27, 2026.
The reinstated levy was for exports of diesel and aviation turbine fuel (ATF). Initially, petrol exports were exempted. The tax was also set up as a Special Additional Excise Duty (SAED) and revised on a fortnightly basis, as it was in 2022.
The latest revision applicable from June 1, 2026 saw tax on Diesel exports being levied at 13.5/litre, for ATF exports at 9.5/ litre and for petrol at 1.5/litre.
A key difference from the regime in 2022 is that the windfall tax in 2026 will be levied on petroleum products exports only. It does not currently tax domestic crude oil production.
The special economic zone (SEZ) refinery of Reliance Industries is also not liable to the levy as per judicial pronouncement that SAED and additional excise duty is not applicable on refineries based in SEZ.
The government reduced the domestic excise duty on petrol and diesel by Rs.10 along with the reinstatement of the windfall tax which will help protect consumers from pump price increases.
Is India's windfall tax still active in 2026?
Yes. On March 27, 2026, the windfall tax was reinstated in India because of the West Asia crisis. Currently, the levy is charged on exports of diesel, petrol and ATF. As of June 1, 2026, the rates are Rs. 13.5/litre on diesel exports, Rs.9.5/litre exports of ATF, and 1.5/litre on petrol exports. Domestic crude oil production is not currently taxed.
What does SAED stand for?
SAED is an acronym for Special Additional Excise Duty. It was the legal framework through which India has been levying its windfall tax on domestic crude oil production and on exports of petroleum products such as diesel, petrol and ATF.
How often were India's windfall tax rates revised?
India has changed the windfall tax rates every 15 days, depending on the international crude oil price fluctuations in the last 15 days. This revision mechanism was undertaken every fortnight, making the levy one of the most dynamic and responsive windfall taxes in the world.
