FAQs on Road Tax in Bihar

Can a vehicle bought in another state be used in Bihar without paying road tax?

No. A vehicle purchased and registered in another state can be driven in Bihar for a short period (typically up to 12 months) without re-registration, but if the owner lives or uses the vehicle in Bihar beyond that period, they must pay Bihar road tax and get the vehicle re-registered locally. Failure to do so can lead to penalties and compliance issues with the Bihar Transport Department.

Is it possible to get a refund of the road tax paid earlier when shifting a vehicle to another state, like Bihar?

Yes, a refund of road tax may be possible when re-registering your vehicle in Bihar after paying lifetime tax in the original state. The vehicle owner must surrender the old registration certificate, provide a No Objection Certificate (NOC), and apply for a refund at the original RTO. The refund depends on the state’s rules and timelines and may take time for processing.

Is road tax or NOC required for a short bike travel from Bihar to another state?

 No. Road tax or NOC is not required for short-term travel up to 12 months. Carry a valid registration, insurance, PUC, and driving licence during travel.

How long can a Bihar-registered car be driven in another state, and what is the road tax cost?

A Bihar-registered car can be driven in another state for up to 12 months. Road tax becomes payable only if the vehicle is permanently shifted and re-registered, with tax based on the destination state’s rates and vehicle value.

Does paying the Bihar road tax once cover future vehicle modifications or ownership changes?

No. Bihar road tax covers road usage for the registered vehicle only. Any major modification or ownership transfer may require a fresh tax assessment or verification by the transport authority.
