Where it stands

India taxes exports of petrol, diesel and aviation turbine fuel (ATF). The Finance Ministry revises the tax every fortnight. The latest revision took effect on 1 September 2026. Petrol exports now pay Rs 1.5 per litre, up from zero. Diesel exports pay Rs 25 per litre, up from Rs 24. ATF exports pay Rs 19 per litre, down from Rs 19.5. Excise duty on petrol and diesel sold inside India did not change. The government imposed the export duty on diesel and ATF on 27 March 2026. Petrol exports came under the duty on 16 May 2026. The government says the duty keeps fuel available in India during the West Asia war. The duty also takes away part of the extra export profit from high world prices.

Background

A windfall tax is a tax on sudden extra profit. India's windfall tax is an extra excise duty on fuel exports. India imported 88.7 per cent of its crude oil in 2025-26. Reliance Industries and Nayara Energy are India's big private refiners. Reliance runs the Jamnagar refinery complex in Gujarat. Nayara runs the Vadinar refinery in Gujarat. In 2022 the consultant FGE put the two refiners at 80 to 85 per cent of petrol and diesel exports. World fuel prices jumped after the war began on 28 February 2026. Exporting fuel then earned more than selling fuel in India. The export duty takes away part of that gain.

How it developed

  1. July 2022 to March 2026
    How it started

    India brought back the fuel export tax on 27 March 2026

    India first taxed fuel exports on 1 July 2022. World oil prices had surged after the Ukraine war. The 2022 tax also covered crude oil produced in India. The government scrapped that tax on 2 December 2024. The United States and Israel struck Iran on 28 February 2026. Crude oil rose from about USD 70 to USD 122 a barrel within a month. On 27 March 2026 the government cut excise duty on petrol and diesel by Rs 10 per litre. The same day an export duty took effect on diesel and ATF. The rates were Rs 21.5 per litre on diesel and Rs 29.5 on ATF. The Finance Ministry has revised the rates every fortnight since.

Why it matters for UPSC

GS3 · Indian economyGS3 · Energy securityGS3 · Public finance

The windfall tax comes under GS Paper 3, Indian economy and energy security. Keep three points straight. The 2026 levy is an excise duty on exports, not a customs duty. The 2026 levy does not touch crude oil produced in India. The 2022 levy did tax domestic crude oil. The Finance Ministry changes the rate by notification under the Central Excise Act. Parliament does not vote on each change. For Prelims, know the full form of SAED and the three fuels covered.

Key terms

Windfall taxA windfall is money that comes suddenly, without extra effort. A windfall tax takes part of that sudden gain. Example: a refinery in Gujarat earns much more on exports after a war raises world fuel prices. The export duty takes part of that extra gain. India collects the windfall tax as an excise duty. The Finance Ministry sets the rate by notification.
Special additional excise duty (SAED)Excise duty is a tax on goods made in India. SAED is an extra excise duty on top of the basic duty. Petrol and diesel sold in India already pay a SAED as part of normal excise. Since 27 March 2026 the Finance Ministry sets a separate SAED rate for exports of diesel and ATF. Petrol exports joined on 16 May 2026. The export rate can change every fortnight.
Road and infrastructure cessA cess is a tax collected for a stated purpose. The road and infrastructure cess is meant for roads and other public works. On fuel exports the government charges this cess together with SAED. The diesel export rate of Rs 25 per litre from 1 September 2026 includes both SAED and this cess. The cess on diesel exports was nil from 15 August 2026.
Aviation turbine fuel (ATF)ATF is the fuel that jet aircraft burn. Indian refineries make ATF from crude oil. Airlines buy ATF at Indian airports. Refineries also export ATF. The export duty on ATF is Rs 19 per litre from 1 September 2026. The ATF export duty peaked at Rs 42 per litre in April 2026.
Refining marginA refinery buys crude oil and sells petrol, diesel and ATF. The refining margin is the gap between those two prices. World fuel prices sometimes rise faster than crude oil prices. The margin on exports then rises. The government sets each export duty after looking at average world prices since the last review.
Import dependenceImport dependence is the share of crude oil that India buys from other countries. The government told the Rajya Sabha in July 2026 that the share was 88.7 per cent in 2025-26. The share was 85.5 per cent in 2021-22. A high share means India feels world price changes quickly.
