The rules

Tax, permits, testing and the practical side

Road tax for goods vehicles

  • Goods vehicles pay tax under the Tamil Nadu Motor Vehicles Taxation Act, 1974. Heavier goods vehicles commonly pay a quarterly tax by laden weight, and lighter classes can be charged at registration.
  • The state revises goods vehicle tax by notification. Check the schedule in force on the date of payment, not the one you paid under last year.
  • The State Transport Authority publishes notices on tnsta.gov.in, and tax for TN vehicles is paid through the Parivahan vehicle services.

Fitness testing

  • MoRTH is moving fitness testing of transport vehicles to registered automated testing stations (ATS) in phases, and the deadlines have been extended before. Before booking, check whether an ATS has been registered for your RTO area or whether the RTO's motor vehicle inspector still conducts the test.
  • Tamil Nadu fleets should check the State Transport Authority's notices for ATS centres approved in their region before the fitness due date, and keep the inspection slip until the new certificate shows on VAHAN.

Permits

  • Home-state goods carriage permits are issued by the Regional Transport Authority. The State Transport Authority handles inter-state matters and the national permit.
  • A national permit is issued by the home-state transport authority. The national permit authorisation that lets the truck run across India is paid online on the Parivahan national permit service, and its annual renewal date is separate from the permit's own validity. Track both dates.
  • Namakkal and Salem fleets that run into Kerala, Karnataka and Andhra Pradesh on a state permit need counter-signature or a temporary permit for each state. Most long-haul operators move to the national permit for that reason.

Practical notes for fleets

  • TN 28 is Namakkal (North), TN 30 is Salem (West), TN 01 is Chennai (Central). Many fleets keep trucks registered across two or three of these.
  • Speed governor certificates are checked on goods vehicles. Keep the certificate with the truck's papers and in the Roadside Pack.
  • Fleets that bring back loads from Kerala and Karnataka collect challans from both states. Check them daily.

Questions about Tamil Nadu

Ask the team

Where do I find the current goods vehicle tax rates for Tamil Nadu?

Road tax in Tamil Nadu is charged under the Tamil Nadu Motor Vehicles Taxation Act, 1974. The current schedule is published by the state transport department; start at tnsta.gov.in. Rates change with the state budget and notifications, so read the version in force on the day you pay.

Does a TN-registered national permit truck pay tax in other states?

It pays road tax to Tamil Nadu as its home state, and an annual national permit authorisation fee online through Parivahan. The authorisation lets it run across India. Track the tax date and the authorisation date separately.

Where is fitness tested in Tamil Nadu?

MoRTH is moving fitness testing of transport vehicles to registered automated testing stations in phases, and deadlines have been extended before. Check the department's notices for the stations that serve your RTO, or ask the RTO whether it still inspects your vehicle class.

What is the penalty if the tax lapses?

Tamil Nadu sets its own grace period and penalty for late payment under the Tamil Nadu Motor Vehicles Taxation Act, 1974. The penalty is charged on top of the tax, so the paid-up date on VAHAN is the one to watch.
