Tamil Nadu cuts Chennai jet fuel tax to 16%, and at its other airports to 1%

Tamil Nadu has cut value-added tax on jet fuel at Chennai airport to 16% from 29% for scheduled airlines on domestic flights, and to 1% at all other airports in the state¹. The new rates run from the midnight between 31 October and 1 November 2026 until 31 October 2027, under a notification from the state's Commercial Taxes and Registration Department¹.

At Chennai, 16% brings Tamil Nadu level with Telangana and below Karnataka's 18%¹. The 1% rate at the state's other airports matches Andhra Pradesh¹. Petroleum ministry data given in the Lok Sabha showed Andhra Pradesh at 1%, Puducherry at 14.5%, Telangana at 16% and Karnataka at 18%, BusinessLine reported¹.

Fuel is the cost airlines want down

Fuel accounts for nearly 45% of airlines' operating expenses, a source told BusinessLine¹. The Federation of Indian Airlines, whose members include IndiGo, Air India and SpiceJet, put the figure higher. It said fuel was taking 50-55% of operating costs against the usual 30-40%, in an October 19 letter to Delhi's chief minister³. The Centre asked states in December 2025 to reduce VAT on ATF to help bring airfares down¹. Tamil Nadu's industries ministry said stronger regional air links support tourism, business travel and market access¹.

Delhi offers a test of what such cuts do. After the capital reduced VAT on ATF from 25% to 7% in May, the airlines' federation said fuel uplift in Delhi rose 40%³. That rate was set for six months, and the federation has asked for it to continue beyond 16 November³.

Export cargo gains only indirectly

Chennai handled 0.37 million tonnes of cargo in the 2024-25 financial year and is India's fourth-busiest airport for cargo⁴.

The scope of the relief matters more than the headline rate for shippers. BusinessLine describes the Chennai rate as applying to ATF supplied to scheduled airlines for domestic flights. It does not say what rate international flights pay, or whether non-scheduled operators such as cargo airlines are covered¹. On that basis, a consignment flying out of Chennai on an international leg should not expect a direct cut in the fuel component of its freight rate. Any gain for exporters would be indirect: cheaper fuel on domestic feeder legs and domestic cargo, or more capacity if lower costs persuade airlines to base aircraft in the city.

Whether that reaches freight bills is a commercial decision. BusinessLine's source said the extent of the benefit depends on how airlines pass on the savings¹. Mint, writing about Goa's cut from 15% to 7%, said lower fuel costs help carriers. It said prices also depend on demand, competition, airport charges and other costs, and that a VAT cut does not automatically mean lower prices⁵. IndiGo welcomed Goa's decision and urged other states to follow, but announced no fare change⁶.

No airline quoted in the BusinessLine report committed to extra capacity at Chennai or to a surcharge revision¹. "We can look forward to lower freight rates and additional capacity out of Chennai," said Santhosh Sundaram, regional chairman for the southern region at the Air Cargo Agents Association of India¹. Separately, J. Krishnan of Chennai forwarder S. Natesa Iyer Logistics called the cut "a small beginning" and said there was "still a long road ahead to regain the lost primacy"¹.

Chennai will still tax fuel above Delhi and Maharashtra

Mint reported that Delhi cut ATF VAT from 25% to 7% and Maharashtra from 18% to 7%⁵. At 16%, Chennai remains above both. Delhi's 7% is temporary unless extended after 16 November³. Goa moved to 7% from 15% on 24 October⁶. Tamil Nadu has joined a queue of states cutting fuel taxes, and it has not matched the lowest rates.

Timing cuts against the benefit. Air freight rates were 26.4% higher than a year earlier in the week to 19 October, TAC Index data show, and IATA data cited by TAC put jet fuel prices up 113.7% year on year to 16 October². TAC said fuel costs "put a hard floor under rates at which airlines will carry cargo"². A cut in state tax on domestic fuel is small next to that.

What to watch

The rate starts on 1 November. The first signals will be surcharge notices: whether any airline or forwarder publishes a Chennai-specific change for domestic cargo, and whether international rates budge. Watch whether ATF uplift at Chennai rises as it did in Delhi, where the federation says uplift is up 40% since the VAT cut³. Then watch Delhi on 16 November, because a lapse there would make Chennai's 16% look more competitive³.
