Bihar RTO Guide 2026: Codes, Road Tax, Online Services & Penalties

As we’ve seen in other states, Bihar too has witnessed a significant increase in vehicle ownership over the last decade. Which means there are an increasing number of registered diverse licences as time goes along, and an overall increased scale of urban mobility, logistics, and transportation. Hence, as a result, there is a healthy amount of paid road tax in Bihar.  Therefore, RTO services in Bihar have become an essential aspect of vehicle ownership.

So, what’s the good news? Most Bihar RTO services are now accessible via the Parivahan portal, which makes registration, tax payments, and licence issuance easier than ever. Whether you’re checking your Bihar RTO vehicle information, downloading Form 35 RTO Bihar, or accessing the Bihar RTO code list PDF, all of the information is available online, if you so desire it.

This 2025 guide breaks down everything you need to know—RTO Bihar codes, road tax rules, online tools, and penalty structures.

It’s not all that complex.

Each regional office under the Bihar RTO framework is assigned a Bihar RTO code to help streamline vehicle tracking and documentation. This also helps verify jurisdiction during traffic offences, vehicle registration, or ownership transfer.

Whether you’re from Patna, Muzaffarpur, or Aurangabad, using the correct RTO code of Bihar ensures smooth registration and compliance.

Here’s a sample of key Bihar RTO codes:

RTO Code	Location	Jurisdiction Type
BR-01	Patna	Urban HQ
BR-06	Gaya	District
BR-07	Muzaffarpur	Regional
BR-26	Aurangabad	District

Registering a new vehicle in Bihar? You’re legally required to complete the RTO Bihar registration within 7 days of purchase. Here’s what you’ll need:

• Form 20: For new registration

Once submitted, your vehicle will be assigned a valid number from Bihar RTO, which reflects your regional office and is used for all future tax, insurance, and challan processes.

The task is simple. 15 years after you first register your vehicle, you have to renew your RC. Paying road tax in Bihar is mandatory at the time of registration, and later every 15 years, with renewal every 5 years. The tax is determined by:
