In a significant move offering relief to domestic refiners, India's Central Government has immediately reduced the windfall tax on the export of petrol, diesel, and aviation turbine fuel (ATF). The revised rates, part of the government's routine fortnightly review, took effect on September 16, 2026, according to an official notification from the Finance Ministry.
Key Tax Reductions Announced
Under the updated levy structure, the export duty on diesel has been lowered by ₹5, moving from ₹25 per litre to ₹20 per litre. Similarly, the tax on ATF exports saw a reduction of ₹4, dropping from ₹19 per litre to ₹15 per litre. For petrol exports, the levy was scaled back by ₹1, settling at ₹0.5 per litre from its previous ₹1.5 per litre.
These adjustments were implemented through modifications to the Special Additional Excise Duty (SAED) and associated cesses. It is important to note that the Ministry clarified that existing excise duty rates on petrol and diesel sold for domestic consumption remain unchanged.
Responding to Global Market Shifts
The government's decision to ease the tax burden on fuel exporters comes amidst shifting dynamics in global crude markets. Oil benchmarks experienced a retreat following a softening of supply bottleneck anxieties. Brent crude futures slipped 1.2% to $104.59 per barrel, while US West Texas Intermediate (WTI) fell 1.1% to $101.29 per barrel, both experiencing losses on September 16.
This cooling trend was partly attributed to Saudi Arabia's move to offer additional crude cargoes to Asian refiners via ship-to-ship transfers off Oman's Sohar port. This action helped alleviate fears that had been triggered by earlier attacks on Saudi infrastructure, broader Middle East tensions involving Iran, the US, and Israel, and potential shipping blockages in the Strait of Hormuz.
Context of Windfall Duties
The windfall duties on crude oil production and fuel exports were initially introduced on March 27, 2026, primarily to protect domestic inventory amid escalating West Asian conflicts. The government periodically reviews these duties to strike a balance between ensuring domestic fuel availability and responding to fluctuating global crude oil prices and refining margins. These regular fortnightly adjustments allow the government to calibrate the tax burden in tandem with international product margins.
