Tamil Nadu cuts jet fuel VAT at Chennai airport from 29% to 16%

The Tamil Nadu government has reduced the value added tax (VAT) on aviation turbine fuel (ATF) for scheduled airlines refuelling at Chennai airport from 29% to 16%, a decision that had been expected for some time.

According to a notification published in the Tamil Nadu Government Gazette, the revised rate will be in force from November 1, 2026, to October 31, 2027.

The State has also changed the rate for scheduled airlines fuelling at airports in Tamil Nadu other than Chennai. For these airports, VAT on ATF has been reduced from 29% to 1%. Separately, for scheduled airlines operating aircraft with a maximum take-off mass of less than 40,000 kg and fuelling at airports in the State other than Chennai, the rate has been reduced from 5% to 1%.

The Chennai airport reduction partially meets a long-standing demand from the Union government and the aviation sector. Aviation turbine fuel accounts for a significant share of an airline's operating cost, and VAT is one of the major factors determining that cost. Because fuel is taxed by States, the rate varies from one State to another, and airlines have consistently cited high State levies as a reason for the cost of flying from particular airports.

Airlines had repeatedly asked the State to bring down the VAT rate on ATF. With the reduction now notified, sources said the expectation is that carriers will respond by improving connectivity and adding new flights from Chennai and other parts of Tamil Nadu, for the benefit of passengers.

The decision comes a few months after Maharashtra and Delhi lowered their VAT rates on ATF, putting pressure on other States with high rates to follow. Tamil Nadu's move brings Chennai closer to the rates prevailing in those markets, though the new 16% rate remains higher than the 1% now applicable at the State's other airports.

The timing of the notification, covering a single financial year, means the concession will be reviewed when the period ends in October 2027. Airlines and industry bodies are likely to press for the lower rate to be retained beyond that window.

For passengers, the immediate effect is not automatic. A cut in fuel tax lowers an airline's input cost, but fares are set by carriers on the basis of demand, competition on each route and overall capacity. The State's notification does not include any condition requiring airlines to pass on the benefit as lower ticket prices, and no airline has yet announced how it will use the savings.

The reduction does, however, change the arithmetic for airlines considering new routes or additional frequencies out of Chennai. Fuel is among the largest single line items in airline budgets, and a 13 percentage point cut in the State levy materially alters the cost of operating from the airport.

Chennai is among the busiest airports in the country and serves as a hub for travel to and from the State's industrial clusters and tourist destinations. Tamil Nadu has sought to expand its aviation footprint, and the government has in the past linked lower fuel taxes to the goal of attracting more flights.

The notification applies to scheduled airlines. It does not alter the rate for general aviation or non-scheduled operators, for whom the earlier rates continue to apply.
