India hikes windfall tax on fuel exports; No impact on domestic retail prices

The Centre has increased the Special Additional Excise Duty (SAED), commonly referred to as the windfall tax, on exports of petrol, diesel and aviation turbine fuel (ATF) for the upcoming fortnight. However, the excise duty applicable to petrol and diesel sold within the country has been left unchanged. The revised rates came into effect on August 3 following notifications issued by the Ministry of Finance.What are the revised windfall tax rates?Under the latest review, the export duty on petrol has been raised to ₹3.5 per litre from ₹2.5 per litre. Diesel exports will now attract a levy of ₹24 per litre, compared with the earlier ₹15.5 per litre, while the duty on ATF exports has been increased to ₹22 per litre from ₹14.5 per litre. The revised structure will remain in force until the next scheduled review unless the government issues fresh orders before then.There will be an additional road and infrastructure cess of ₹1.5 per litre on exports of diesel, which will take the eventual duty to ₹25.5 per litre.The move reflects the government’s ongoing practice of adjusting export duties in response to developments in global energy markets. Windfall taxes are typically imposed when refiners benefit from stronger international fuel prices and higher refining margins, leading to unusually large profits.Will the latest duty hike affect fuel prices in India?Despite the increase in export duties, there is no change in the excise duty charged on petrol and diesel sold in the domestic market. As a result, consumers are unlikely to experience any immediate impact on retail fuel prices solely due to this revision.The higher levy will primarily affect refiners exporting fuel products by increasing their tax outgo over the next two weeks. India’s fortnightly review mechanism allows the government to recalibrate these duties based on fluctuations in crude oil prices, refining economics and export profitability, ensuring tax levels remain aligned with prevailing market conditions.First Published: Aug 3, 2026 8:07 PM IST
