India Raises Windfall Tax on Diesel, ATF Exports

India revised its windfall tax on petroleum product exports with effect from 16 July 2026. The Ministry of Finance issued the revised rates on 15 July 2026 under the fortnightly review mechanism for fuel export duties.

Windfall Tax on Petroleum Exports

Windfall tax is an additional levy imposed on extraordinary gains from sectors such as crude oil and petroleum refining. In India, the tax applies to exports of diesel, aviation turbine fuel and petrol by refiners, and it does not apply to domestic sales of these fuels.

Revised Duty Rates

The export duty on diesel increased by ₹7 per litre, from ₹8.50 per litre to ₹15.50 per litre. The export duty on aviation turbine fuel increased by ₹7 per litre, from ₹7.50 per litre to ₹14.50 per litre. The export duty on petrol was reduced by ₹1.5 per litre, from ₹4 per litre to ₹2.50 per litre.

Review Mechanism and Market Factors

India reviews fuel export duties every fortnight to align the levy with changes in international crude oil prices and refining margins. The July 2026 revision followed a rise in global crude oil prices linked to tensions between the United States and Iran and concerns over disruption in the Strait of Hormuz.

Important Facts for Exams

• Windfall tax is a special levy on unexpected or excess profits in specific sectors.
• Aviation turbine fuel is commonly used in civil aviation and military aircraft.
• The Strait of Hormuz is a narrow sea passage between the Persian Gulf and the Gulf of Oman.
• India uses fortnightly revisions for certain fuel export duties.

Domestic Supply and Export Policy

The duty revision is linked to export incentives for refiners and domestic availability of petroleum products. The tax structure is used to regulate export flows when international price movements raise refinery margins.
