Centre cuts windfall tax on petrol, diesel and ATF exports to ₹0.5–₹20/litre
Synopsis
Key Takeaways
The Centre on 17 September 2026 reduced windfall tax and export levies on petrol, diesel, and aviation turbine fuel (ATF) as part of its routine fortnightly review of petroleum product duties. The revision, notified by the Finance Ministry, lowers export-facing levies across all three fuel categories while leaving domestic excise duty rates unchanged.
Revised Duty Rates at a Glance
Under the latest notification, the export duty on petrol has been trimmed to ₹0.5 per litre, comprising entirely of Special Additional Excise Duty (SAED) of ₹0.5 per litre, with the Revenue Integration Charge (RIC) remaining nil. For diesel, the combined export levy now stands at ₹20 per litre — fully via SAED — also with no RIC component. The ATF export levy has been brought down to ₹15 per litre through SAED.
What Stays Unchanged
The Finance Ministry clarified that existing excise duty rates on petrol and diesel cleared for domestic consumption remain unaltered. Consumers at the pump will therefore see no direct change in retail fuel prices from this particular revision.
Pattern of Recent Revisions
The current cuts follow a series of adjustments over the preceding weeks. In the revision effective 1 September, the government had already moved to reduce the diesel export levy to ₹1 per litre from ₹3 per litre and cut the windfall tax on diesel exports to ₹19 per litre from ₹24 per litre. Prior to that, in August, duties had been raised sharply — petrol export duty climbed to ₹3.5 per litre from ₹2.5 per litre, total diesel duty jumped to ₹25.5 per litre from ₹15.5 per litre, and ATF levies rose to ₹22 per litre from ₹14.5 per litre. The current revision effectively rolls back a significant portion of those August increases.
Why the Government Reviews These Duties
India introduced windfall taxes on domestically produced crude oil and petroleum product exports in mid-2022, when global refinery margins surged following the Russia-Ukraine conflict. The fortnightly review mechanism was built in to track real-time movements in international crude oil prices and refinery margins, allowing the government to calibrate levies without legislative delays. Periods of elevated global crude prices typically push these duties higher, while softening prices — or political pressure to support refiner profitability — tend to bring them down. The latest reduction comes amid continued geopolitical volatility in global oil markets and shifting export economics for Indian refiners.
Implications for Refiners and Exporters
Lower export duties improve the net realisation for Indian public sector and private refiners — including Indian Oil Corporation (IOC), Bharat Petroleum (BPCL), Hindustan Petroleum (HPCL), and Reliance Industries — when they ship refined products overseas. A reduced windfall tax also signals that the government views current global margins as less 'extraordinary' than they were in earlier months, easing the tax burden on export-oriented refinery operations. The next fortnightly review is expected in early October.
