Windfall Tax Revised: Petrol Export Levy Scrapped, Diesel and ATF Export Duties Raised

What happened

The government on Saturday, 31 October, carried out its latest fortnightly revision of the windfall tax on fuel exports, and moved the three main products in different directions. According to a Finance Ministry notification reported by PTI, the levy on petrol exports has been removed altogether, down from ₹2.5 a litre. The levy on diesel exports, made up of a special additional excise duty and a road and infrastructure cess, rises by ₹3 to ₹11.5 a litre. Aviation turbine fuel (ATF) exports now attract ₹11 a litre, up 50 paise.

The new rates took effect on 31 October and apply for the next 15 days. The ministry made clear that duties on petrol and diesel sold within India are unchanged, so the decision does not by itself change what motorists pay at the pump.

Why people are searching

A "windfall tax" is a levy on unusually large profits that companies earn because of outside events rather than their own efforts. In India's case it is charged on fuel that refiners ship abroad, and it is reset every two weeks, so each revision prompts a fresh wave of searches from people trying to understand what changed and whether it affects them.

This round drew more attention because of diesel. The Hindu, citing data from the analytics firm Kpler, reported that India's diesel exports reached about 700,000 barrels a day in October, the highest since September 2025, amid a supply crunch in Europe. A higher levy makes those exports less attractive.

Why the tax exists

The export duties were introduced on 27 March, in the backdrop of the conflict in West Asia, and extended to petrol from 16 May. The government's stated aim is to keep enough fuel in the domestic market by discouraging exports, and to stop exporters from gaining unfairly from the gap between high international prices and domestic prices. Each review is based on average international benchmark prices for crude oil, petrol, diesel and ATF since the previous revision, The Hindu reported.

What comes next

Kpler's Sumit Ritolia said in a social media post, quoted by The Hindu, that India's diesel exports are expected to ease to 500,000–550,000 barrels a day in November and December as domestic demand peaks. The next review of the export levies is due in about two weeks, and the rates can rise, fall or be removed depending on international prices.
