What it is
What the national permit authorisation proves
The authorisation is the annual part of a national permit. It is a fee paid online every year that makes the home-state permit valid across the country. The fee is a consolidated amount shared among the states, which is why a national permit truck does not pay separate goods vehicle tax at every state border. Because it falls due every year and is paid online in minutes, it is also the national permit document most often missed.

How to renew
4 steps, in order
PRACHSO does not issue or renew any government document. These are the steps on the official service, or the ones your appointed agent follows.
- 1
Check the authorisation's expiry date on the last authorisation slip or the vehicle's record. It is a different date from the base permit.
- 2
Make sure the base national permit itself is valid for the period you are paying for.
- 3
Pay the authorisation fee online through the national permit service on Parivahan, using the vehicle's registration number.
- 4
Download the authorisation and keep a copy with the permit in the cabin, and check that the new validity shows on the vehicle's record.
Penalty for a lapse
Without a current authorisation, the national permit does not cover the truck outside its home state. Operating there is treated as using the vehicle without a valid permit, which is punishable under Section 192A of the Motor Vehicles Act: up to ₹10,000, and the section also allows imprisonment. States can set different compounding amounts.

Common mistakes
Where fleets slip
- Treating the national permit as one date and missing the yearly authorisation, so a truck on a Ludhiana to Chennai run is out of permit at the first state border.
- Paying the authorisation for the wrong vehicle number when several trucks renew in the same week.
- Not keeping the downloaded authorisation with the permit, so the driver cannot show it at a checkpoint.
How PRACHSO tracks it
The reminder goes to whoever has to act
PRACHSO keeps the authorisation as its own row on each truck, separate from the base permit, and sends the owner the payment reminder 30 days out. When the munshi marks it done, the new authorisation slip goes into the vault and into the driver's Roadside Pack.

Questions about the national permit authorisation
Answers from the Motor Vehicles Act, the Central Motor Vehicles Rules and the official renewal services. Last checked 12 Nov 2026.
How often is the national permit authorisation renewed?
Every year. The authorisation fee is paid online for one year at a time.
Is the authorisation fee the same as road tax?
No. The authorisation fee is the consolidated fee for operating across states under the national permit scheme. The home state's road tax is separate and still due.
Can the authorisation be paid after it lapses?
It can be paid again, but every day the truck runs outside its home state without it is a day without a valid permit. Pay before the expiry date.
