Tamil Nadu Cuts Jet Fuel VAT: 16% at Chennai, 1% Elsewhere

Tamil Nadu has cut the value added tax on aviation turbine fuel at Chennai airport from 29% to 16%, and to 1% at the state’s other airports, from 1 November 2026.

The numbers

The Commercial Taxes and Registration Department issued three notifications under the Tamil Nadu Value Added Tax Act, 2006, on Friday 23 October 2026, as reported by DT Next the same day. The reduced rates apply to fuel sold to scheduled airlines from 1 November 2026 and are valid until 31 October 2027.

Aviation turbine fuel (ATF) is outside GST, so each state sets its own sales tax on it. That makes the state rate one of the few levers a government has over the cost of flying from its airports. For Chennai, the cut brings the tax closer to the rates in other large aviation states; for airports such as Coimbatore, Madurai, Tiruchirappalli and Thoothukudi, it brings the tax close to zero.

What the notifications do

According to the DT Next report, the three notifications work as follows:

• ATF sold to scheduled airlines at Chennai airport: VAT cut from 29% to 16%.
• ATF sold to scheduled airlines at other airports in Tamil Nadu: from 29% to 1%.
• Fuel for aircraft with a maximum take-off mass below 40,000 kg at airports outside Chennai: from 5% to 1%.

The 40,000 kg category covers smaller aircraft such as the turboprops used on short regional routes. To claim the lower rate, oil companies must file declarations signed by the purchasing airline with their monthly returns to the assessing officer, identifying the domestic flight for which the fuel was bought.

Why the tax on jet fuel matters

Fuel is one of an airline’s largest costs. In a Lok Sabha answer of 15 December 2022 (Unstarred Question No. 1423), the Ministry of Civil Aviation agreed that ATF forms a major portion of airline costs and said the Centre had taken up high VAT rates with the states. A state tax charged as a percentage of the fuel price rises with the price, so when fuel costs climb the tax bill climbs with it.

The DT Next report says the cut was meant to give relief to carriers facing high fuel costs. It notes that the Federation of Indian Airlines had asked in September for lower taxes on ATF, citing higher fuel bills, airspace restrictions and other added costs, and had warned that airlines might drop routes that were no longer viable without relief. The report adds that the Centre has introduced a price-stabilisation support mechanism for airlines during the West Asia crisis.

How other states compare

Tamil Nadu’s 29% was among the highest ATF rates in India. The annex to the 2022 Lok Sabha answer, using Indian Oil data, listed Tamil Nadu and Bihar at 29%, Delhi at 25% and Karnataka at 18%. Two large aviation markets cut their rates in May 2026. All India Radio News, the public broadcaster, reported on 17 May that Delhi had cut VAT on ATF from 25% to 7%, and on 15 May that Maharashtra had cut it from 18% to 7%. The Union Civil Aviation Minister, Ram Mohan Naidu, welcomed both cuts.

Even after the cut, Chennai’s 16% is more than double the 7% now charged in Delhi and Maharashtra. Airlines planning where to refuel on multi-stop routes can weigh these differences, so the gap still matters. The 1% rate at other Tamil Nadu airports is far below any of the rates listed here.

A lower rate the state has used before

Tamil Nadu has used a 1% rate as a targeted incentive before. In November 2019, G.O. Ms. No. 175 of the Commercial Taxes and Registration Department cut VAT on ATF from 29% to 1% for domestic freighter aircraft departing from non-metropolitan airports, and from 5% to 1% for freighters under 40,000 kg. That concession had tight conditions: the aircraft had to arrive after 11 pm, leave before 7 am and stay at least three hours, and it ran for six months. The 2026 cut is broader, covering all scheduled domestic flights, and runs for a year.

The notifications do not say how much revenue the state expects to give up.

What this means for you

• Do not expect an immediate fall in fares on a particular flight. Watch instead for new or restored routes, especially from airports outside Chennai.
• Travellers from Coimbatore, Madurai, Tiruchirappalli and other Tamil Nadu airports stand to gain most, because the rate there falls to 1%.
• The cut is for one year, to 31 October 2027. Whether it is extended will depend on what airlines do with it.
• ATF remains outside GST, so state rates will keep differing until the GST Council decides otherwise.
