The Indian government has reduced windfall taxes on exports of petrol, diesel and aviation turbine fuel (ATF), providing some relief to refiners exporting petroleum products. The revised rates came into effect on August 15, 2026, as part of the Centre’s fortnightly review of export levies based on changes in global crude oil and petroleum product prices.
Under the latest notification, the export duty on petrol has been reduced to zero from Rs 3.5 per litre. The levy on diesel exports has been lowered to Rs 24 per litre from Rs 25.5 per litre, while the duty on ATF exports has been cut to Rs 19.5 per litre from Rs 22 per litre. The changes could improve export economics for Indian refiners while maintaining a tax on diesel and jet fuel shipments.
Petrol Export Duty Reduced to Zero
The most significant change is the complete removal of the export levy on petrol.
The government has reduced the special additional excise duty (SAED) on petrol exports from Rs 3.5 per litre to nil.
This gives refiners exporting petrol a direct reduction in their tax burden and could improve margins on international sales.
| Fuel | Previous Export Levy | New Export Levy | Change |
|---|---|---|---|
| Petrol | Rs 3.5/litre | Nil | Rs 3.5/litre reduction |
| Diesel | Rs 25.5/litre | Rs 24/litre | Rs 1.5/litre reduction |
| ATF | Rs 22/litre | Rs 19.5/litre | Rs 2.5/litre reduction |
The revised rates apply from August 15 for the latest fortnightly period.
Diesel Export Tax Cut to Rs 24
The government has reduced the export levy on diesel by Rs 1.5 per litre.
The SAED on diesel exports now stands at Rs 24 per litre, compared with Rs 25.5 per litre previously.
Although the reduction is relatively modest compared with the petrol adjustment, it reduces the tax burden on India’s large refining companies that sell diesel in overseas markets.

ATF Export Duty Cut to Rs 19.5
The government has also reduced the levy on aviation turbine fuel exports.
The ATF export duty has been lowered from Rs 22 per litre to Rs 19.5 per litre.
The move could provide some relief to Indian refiners that export jet fuel into international markets.

Why India Uses Windfall Taxes
Windfall taxes are designed to capture extraordinary profits that companies can earn when global energy prices rise sharply.
India first introduced windfall taxes on crude oil and petroleum product exports in July 2022 following a surge in international oil prices.
The government sought to capture a portion of unusually high refining and crude-production margins while protecting domestic fuel availability.

The rates are periodically adjusted according to market conditions.
Windfall Taxes Were Reintroduced in 2026
India had withdrawn the earlier windfall tax regime in 2024.
The export levies were subsequently reintroduced in 2026 as global oil prices rose sharply amid geopolitical tensions in the Middle East.
The government has since been reviewing the rates every two weeks.
The latest reduction indicates that market conditions have changed enough for the Centre to reduce the export burden on petroleum products.
Fortnightly Reviews Allow Faster Policy Changes
The government regularly revises petroleum export levies rather than maintaining a fixed rate for a long period.
This allows tax rates to respond to changes in international crude prices and petroleum-product margins.

The system allows the government to respond relatively quickly to changes in the global energy market.
The Latest Move Follows an Earlier Tax Increase
The latest reduction comes only about two weeks after the government increased some export levies.
On August 3, the petrol export levy had been raised to Rs 3.5 per litre from Rs 2.5 per litre.
The diesel levy was increased to Rs 24 per litre from Rs 15.5 per litre at that time, while the ATF levy was raised to Rs 22 per litre.
The latest notification reverses part of that increase.
Policy Has Changed Rapidly in 2026
The movement in export levies highlights how quickly India’s fuel-tax policy has responded to global energy-market conditions this year.
The government has used the duties both to capture extraordinary export profits and to influence the allocation of refinery output between domestic and international markets.

Refiners Could Benefit From Lower Export Levies
Indian refiners are among the companies most directly affected by changes in petroleum-product export duties.
Lower levies can improve the net realization on every exported litre, assuming international prices remain unchanged.

The benefit will vary depending on the product and the market in which it is sold.
Reliance Industries Could Be Affected
Reliance Industries operates one of the world’s largest refining complexes at Jamnagar and has significant exposure to international petroleum-product markets.
Changes in export levies can therefore influence the economics of its refining and fuel-export operations.
However, the company’s overall performance depends on many factors beyond Indian export taxes, including global refining margins, crude prices, petrochemicals and domestic demand.
State-Owned Refiners Could Also Benefit
Indian Oil, Bharat Petroleum and Hindustan Petroleum also operate large refining businesses.
Lower export levies could provide some benefit when these companies sell surplus or commercially attractive petroleum products overseas.
The overall impact will depend on how much product each company exports during the relevant period.
Lower Taxes Could Improve India’s Export Competitiveness
Indian refiners compete with producers in other major refining hubs across Asia and the Middle East.
Export taxes increase the effective cost of supplying international customers.
Reducing those taxes can make Indian petroleum products more competitive.

The Move Does Not Mean Fuel Prices Will Fall
The latest announcement concerns taxes on exports of petroleum products.
It does not directly reduce the domestic excise duty on petrol or diesel sold to Indian consumers.
Therefore, the move should not automatically be interpreted as a reduction in retail petrol or diesel prices.

Different policy mechanisms
Consumers at Indian fuel stations should not expect an immediate price reduction simply because export duties have been lowered.
Domestic Fuel Supply Remains Important
The government has historically used export restrictions and taxes partly to ensure sufficient domestic availability of petroleum products.
When international prices rise sharply, refiners may have greater incentives to export products.
Higher export levies can reduce that incentive and encourage supplies to remain available domestically.
The latest reduction suggests that the government currently sees less need for such a high export tax burden.
Global Oil Prices Remain a Key Factor
The economics of India’s petroleum exports remain closely linked to international crude oil and refined-product prices.
When global prices rise, refinery margins can change rapidly.
Higher prices can increase export profitability, but they can also increase the cost of crude feedstock.

Geopolitical Risks Can Change the Policy Again
The 2026 windfall-tax regime has been closely linked to geopolitical developments and oil-market volatility.
Any significant disruption to global oil supply could push crude and petroleum-product prices higher.
If refining margins rise sharply, the government could potentially increase export levies again during a future review.
Conversely, weaker prices or narrower margins could lead to further reductions.
What the Latest Cut Means for Refiners
The immediate impact is a reduction in the tax burden on exported fuel.
The biggest benefit is for petrol exporters because the levy has been removed entirely.
Diesel and ATF exporters receive smaller reductions.
The policy therefore provides selective relief rather than a complete withdrawal of petroleum export taxes.
What It Means for the Government
For the government, lowering export duties could reduce revenue collected from petroleum-product exports.
However, the decision may support refinery economics and keep India’s exports competitive.
The government’s approach suggests that tax revenue is being balanced against broader energy-market conditions.
What It Means for India’s Fuel Exports
Lower export levies could support petroleum-product exports if international demand remains strong.
Indian refiners have substantial refining capacity and are important suppliers to overseas markets.
A lower tax burden can improve their ability to compete with other Asian refining hubs.
What It Means for the Energy Market
The latest decision demonstrates that India’s petroleum taxation remains closely tied to international market conditions.
The government is using export levies as a flexible policy tool rather than maintaining a permanent fixed rate.
This creates a dynamic environment for refiners and traders.
What Investors Should Watch
Investors should monitor:
- Global crude oil prices
- Diesel refining margins
- Petrol refining margins
- ATF prices
- India’s petroleum-product exports
- Future fortnightly tax revisions
- Domestic fuel demand
- Refinery utilization
- Geopolitical developments
- Profitability of major refiners
The next government review will provide another indication of whether the current reduction is part of a broader downward trend.

NEXT FORTNIGHTLY REVIEW
The Bigger Picture
India’s decision to reduce windfall taxes on petrol, diesel and aviation turbine fuel exports provides some relief to domestic refiners after a period of sharply changing petroleum-product export levies. Effective August 15, the petrol export duty has been eliminated, while the diesel levy has been reduced to Rs 24 per litre and the ATF levy to Rs 19.5 per litre. The move comes only two weeks after the government increased some of these duties, underscoring how closely India’s fuel-tax policy is responding to international oil prices and refining margins.
The reduction could improve the economics of India’s petroleum-product exports, particularly for large refiners with significant overseas sales. However, it does not directly reduce domestic petrol or diesel taxes and therefore should not be viewed as an immediate cut in retail fuel prices. The government continues to use fortnightly adjustments to balance export competitiveness, domestic fuel availability and tax revenue. Future changes will largely depend on global crude prices, refining margins and geopolitical developments.
Looking Ahead
The next fortnightly review will be closely watched by refiners, traders and investors because the government’s export levies can change rapidly when international oil-market conditions shift. If global petroleum-product margins weaken further, additional reductions could follow. On the other hand, a sharp rise in crude prices or refining margins could prompt the government to restore higher levies.
For Indian refiners, the latest reduction provides a modest improvement in export economics, with petrol exporters receiving the largest immediate benefit from the removal of the levy. The broader significance is that India is continuing to use petroleum export taxes as a flexible market-policy instrument. As global energy markets remain volatile, the balance between domestic supply, export profitability and government revenue will continue to determine the direction of future windfall-tax changes.
