Government Cuts Windfall Tax on Diesel and ATF Exports, Raises Petrol Export Duty

New Rates Effective July 1 as Falling Global Oil Prices Prompt Policy Adjustment

The Central Government has revised the windfall tax structure on petroleum exports, reducing the export duty on diesel and aviation turbine fuel (ATF) while increasing the levy on petrol exports. The revised rates, notified through a government order, will come into effect from July 1.

The move comes amid a decline in global crude oil prices following easing geopolitical tensions and the resumption of shipping through the Strait of Hormuz. The revised tax structure is aimed at balancing domestic fuel availability while responding to changing international market conditions.

The government has also expanded export exemptions for public sector oil companies to include Mauritius and the Maldives, in addition to existing exemptions for neighbouring countries.

What Are the Revised Windfall Tax Rates?

According to the latest notification, the government has reduced the export duty on diesel to ₹8.5 per litre, down from the earlier ₹14 per litre.

Similarly, the export duty on aviation turbine fuel (ATF) has been lowered from ₹12.5 per litre to ₹7.5 per litre.

However, the government has taken a different approach for petrol exports by increasing the export duty from ₹1.5 per litre to ₹4 per litre.

Officials indicated that the higher levy on petrol exports is intended to ensure adequate domestic availability while allowing refiners to continue exporting surplus production.

The revised rates will become effective from July 1, replacing the previous duty structure.

Why Has the Government Changed the Tax Structure?

The decision follows a significant correction in international crude oil prices over recent weeks.

Global oil prices had previously surged above $126 per barrel due to geopolitical tensions and concerns over supply disruptions, particularly around the Strait of Hormuz, one of the world’s busiest oil shipping routes.

However, easing regional tensions and the restoration of maritime traffic have reduced fears of prolonged supply shortages, leading to a sharp decline in crude prices.

With market conditions stabilizing, the government has adjusted export duties to better reflect current pricing dynamics while protecting domestic fuel supplies.

Industry experts believe the move provides refiners with greater flexibility as international energy markets normalize.

Global Oil Market Outlook Remains Stable

Analysts expect crude oil prices to remain relatively moderate over the coming year.

According to economists’ forecasts, Brent crude is expected to average around $84.50 per barrel in 2026, lower than the previous estimate of $90.44 per barrel made last month.

The revised outlook reflects improved supply conditions, easing geopolitical uncertainty, and expectations of balanced global demand.

Lower crude prices generally reduce pressure on importing countries such as India, helping improve trade balances, moderate inflation, and lower input costs for industries dependent on petroleum products.

The government’s decision to revise windfall taxes aligns with these changing market fundamentals.

Export Exemptions Expanded for Public Sector Oil Companies

Alongside revising export duties, the government has widened the scope of exemptions available to public sector oil marketing companies.

When the export levy was originally introduced, exports of petrol, diesel, and ATF to Nepal, Bhutan, Bangladesh, and Sri Lanka were exempt from the windfall tax.

The latest notification extends this exemption to include exports to Mauritius and the Maldives.

The decision is expected to support India’s energy trade relationships with friendly nations while ensuring uninterrupted fuel supplies to strategic partner countries.

These exemptions apply specifically to exports undertaken by public sector oil companies.

What Does This Mean for India’s Energy Sector?

The latest revision demonstrates the government’s flexible approach toward managing fuel exports in response to global energy market developments.

Windfall taxes were originally introduced to capture extraordinary profits earned by refiners during periods of exceptionally high crude oil prices while ensuring sufficient domestic fuel availability.

As international oil prices have moderated, lowering export duties on diesel and ATF could improve export competitiveness for Indian refiners and help maintain healthy refining margins.

At the same time, the increase in petrol export duty reflects the government’s continued focus on protecting domestic supply, particularly during periods of strong local demand.

The expanded export exemptions also reinforce India’s commitment to supporting regional energy security through reliable fuel supplies to neighbouring and partner countries.

Going forward, the government is expected to continue reviewing windfall tax rates periodically based on global crude prices, refining margins, and domestic fuel requirements.

With international oil markets remaining volatile, future revisions are likely to depend on geopolitical developments, global demand trends, and India’s energy security priorities.
