The government on Saturday, April 11, 2026, hiked export duty, or windfall tax, on diesel to ₹55.5 per litre and on aviation turbine fuel (ATF) to ₹42 per litre. Officials said the move aims to discourage exports and ensure adequate fuel availability in the domestic market. The new windfall taxes will kick in immediately.

The decision is expected to have a significant impact on the domestic fuel market. Sources confirmed that the government has been closely monitoring the situation and decided to take this step to stabilize fuel prices.

The windfall tax on fuel exports is based on cracks, or margins, that refiners earn on overseas shipments, primarily the difference between the international oil price realised and the cost.

Impact On Fuel Exports

The hike in windfall tax on diesel and ATF exports is expected to reduce exports and increase domestic supply. Government sources said the move will help in stabilizing domestic fuel prices. The tax on diesel exports has been increased from ₹21.5 per litre to ₹55.5 per litre, while the tax on ATF exports has been increased from ₹29.5 per litre to ₹42 per litre.

Experts said the move will have a positive impact on the domestic market, as it will lead to increased availability of fuel and help in reducing prices. However, it may have a negative impact on the export-oriented refineries.

Meanwhile, witnesses said the decision will also affect the aviation industry, as the increase in ATF prices will lead to higher operating costs for airlines.

Historical Context

India first imposed a windfall tax on exports by oil refiners and producers in July 2022, announcing levies on petrol, diesel, and domestically produced crude oil. The government later extended the levy on exports of petrol, diesel, and ATF, as private refiners sought to sell fuel overseas to capitalize on robust refining margins rather than selling locally.

The windfall tax on fuel exports has been revised several times since its introduction. In January 2026, the government raised the windfall tax on petroleum, crude oil, and aviation turbine fuel.

Despite this, the government has been facing pressure to take steps to stabilize domestic fuel prices. The latest hike in windfall tax on diesel and ATF exports is seen as a step in this direction.

Reactions And Expectations

The decision to hike windfall tax on diesel and ATF exports has been welcomed by some sections of the industry, while others have expressed concerns. Officials said the move will help in stabilizing domestic fuel prices and ensuring adequate supply.

However, some experts have expressed concerns that the move may have a negative impact on the export-oriented refineries and the aviation industry. They said the increase in ATF prices will lead to higher operating costs for airlines.

Meanwhile, sources confirmed that the government is closely monitoring the situation and is ready to take further steps if needed to stabilize domestic fuel prices.

Future Outlook

The decision to hike windfall tax on diesel and ATF exports is expected to have a significant impact on the domestic fuel market. Government sources said the move will help in stabilizing domestic fuel prices and ensuring adequate supply.

However, the situation is being closely monitored, and further steps may be taken if needed. Experts said the move will have a positive impact on the domestic market, as it will lead to increased availability of fuel and help in reducing prices.

In contrast, the move may have a negative impact on the export-oriented refineries and the aviation industry. Despite this, the government is expected to continue taking steps to stabilize domestic fuel prices and ensure adequate supply.
