Tamil Nadu is preparing to reduce its Value Added Tax (VAT) on Aviation Turbine Fuel (ATF), currently among the highest in the country at 29 per cent, with the revision expected to be announced in the upcoming State Budget. The move, being pursued under the government led by Tamilaga Vettri Kazhagam (TVK) chief C. Joseph Vijay, is aimed at lowering airline operating costs and sharpening the competitiveness of the State's aviation sector against neighbouring states.

Where Tamil Nadu Stands Against Neighbours

Data submitted by the Union Ministry of Petroleum and Natural Gas to the Lok Sabha earlier this year lays bare the competitive gap Tamil Nadu faces. Andhra Pradesh levies just 1 per cent VAT on ATF, while Puducherry charges 14.5 per cent, Telangana 16 per cent, and Karnataka 18 per cent. Kerala follows a distinct structure — a 5 per cent sales tax plus a 1 per cent cess, with its four airports — Thiruvananthapuram, Kochi (Nedumbassery), Kannur, and Kozhikode — each levying an additional 1 per cent tax and 1 per cent cess.

At 29 per cent, Tamil Nadu's ATF tax rate is substantially higher than any of these, a disparity that industry stakeholders argue has long disadvantaged the State's airports in attracting airline capacity.

National Trend Driving the Push

The proposed revision comes amid a broader national rationalisation of ATF taxes. Approximately two months ago, both Maharashtra and Delhi cut their VAT on aviation fuel sharply — Maharashtra reduced its rate from 18 per cent to 7 per cent with no specified time limit, while Delhi brought its rate down from 25 per cent to 7 per cent for an initial six-month period. The Union government has repeatedly urged states to rationalise ATF levies, citing the fuel's outsized share in airline operating expenses.

Notably, ATF accounts for one of the single largest cost items for carriers operating in India, and lower state taxes have historically correlated with improved route connectivity and increased airline presence at regional airports.

What Officials Have Said

Officials familiar with the proposal confirmed that the government is actively reviewing the existing 29 per cent VAT structure, though the exact revised percentage has not yet been finalised. The reduction is expected to be formally announced as part of the forthcoming State Budget, according to reports.

Impact on Aviation and Connectivity

If implemented, the cut would make Tamil Nadu one of the latest states to align with a more competitive ATF tax regime, potentially improving the economics of operating routes into and out of airports including Chennai. Industry stakeholders have long argued that rationalised fuel taxes would reduce costs, expand air connectivity, and encourage airlines to add services to underserved destinations within the state.

The move would also respond to longstanding appeals from the Centre, which has flagged high state-level ATF taxes as a structural drag on India's aviation growth ambitions. How deep the cut ultimately goes will determine how meaningfully Tamil Nadu closes the gap with its southern neighbours.
