Key Concepts: Excise Duty and Windfall Tax
Context:
Amid the escalating West Asia conflict and the subsequent threats to the Strait of Hormuz, global crude oil prices recently surged past $120 per barrel.
In response, the Indian government implemented a dual taxation strategy in late March 2026 to shield domestic consumers and ensure energy security
Recent Policy Changes:
Slashing Excise Duty:
To offset the massive under-recovery losses of state-run Oil Marketing Companies (OMCs) and keep retail fuel prices frozen, the Centre slashed the Special Additional Excise Duty on petrol by ₹10 (from ₹13 to ₹3 per litre) and on diesel from ₹10 to zero.
Reimposing Windfall Tax:
Conversely, the government reinstated a Windfall Tax on fuel exports.
It levied a tax of ₹21.5 per litre on diesel exports and ₹29.5 per litre on Aviation Turbine Fuel (ATF) exports.
This move aims to discourage private refiners from exporting fuel for abnormal profits and to ensure adequate domestic supply.
Key Concepts:
Excise Duty:
It is an indirect tax levied by the central government on the production, licensing, and sale of specific goods produced within the country (such as petroleum products).
Unlike customs duty, which is levied on imports, excise duty is an inland tax.
Windfall Tax:
It is a special, higher tax rate imposed by governments on companies or entire industries that experience a sudden, unexpectedly large profit (a "windfall gain").
These abnormal profits are typically the result of external, unprecedented events—such as a geopolitical crisis, war, or global supply chain shock—rather than the company's own investment strategy, innovation, or expansion.
The tax aims to redistribute these excess profits, generate additional government revenue during periods of economic instability, and disincentivize exports to prioritize the domestic market.
