In Bihar, the road tax rates for private and commercial vehicles differ from one another. The requirement to pay road tax arises at the time of purchasing a vehicle; if you are buying a new car, bike or scooter, you are required to deposit the applicable road tax alongside the actual purchase price of the vehicle.
In Bihar, the road tax rates for various types of vehicles are determined by the Transport Department, Government of Bihar. If you are planning to purchase a new vehicle and wish to know the road tax you will be required to pay, please read this article, as we have done a detailed discussion on this subject here.
Road Tax In Bihar 2026
In Bihar, the road tax for various private vehicles such as bikes, scooters, and cars is not a fixed amount; rather, it is calculated as a percentage of the vehicle’s ex-showroom price. The details for which are as follows:
- If the price of the vehicle you intend to purchase does not exceed ₹1 lakh, you will be required to pay 8% of its ex-showroom price as road tax.
- If the price is greater than ₹1 lakh but falls within the range of ₹8 lakh (or less), the road tax payable in this scenario is 9% of the vehicle’s ex-showroom price.
- If the vehicle you are considering purchasing is priced above ₹8 lakh but at or below ₹15 lakh, the applicable road tax is 10%.
- For all vehicles priced above ₹15 lakh, the applicable road tax is 12% of the ex-showroom price.
Please note that when purchasing a new vehicle, in addition to the ex-showroom price and road tax, you are also required to pay various other charges, including registration certificate fees, High-Security Registration Plates fee, and others.
The rules regarding road tax for commercial vehicles in Bihar are slightly different; to understand them, you must carefully read all the points provided below.
3W Commercial Vehicle Road Tax
For commercial three-wheeler vehicles, the road tax depends on their seating capacity. In Bihar, the road tax differs slightly for commercial three-wheelers with a seating capacity of four passengers versus those with a capacity of seven passengers, we have discussed below.
- For a 3W commercial vehicle with a seating capacity of four passengers, the road tax amounts to ₹6,700 and ₹10,000 for periods of 5, 10, and 15 years, respectively.
- For a 3W commercial vehicle with a seating capacity of seven passengers, the road tax for 5, 10, and 15 years stands at ₹2,000, ₹11,000, and ₹15,000.
You do not need to be concerned regarding the duration of this period. A 5-year term implies that if you pay the applicable road tax for five years, you can use the vehicle commercially on public roads with complete peace of mind for that entire duration.
However, if you wish to continue using it beyond those five years, you will be required to pay the applicable charges once again.
A better option would be to register your commercial vehicle for a minimum period of 10 years; this ensures you can utilize it effectively without having to deal with the hassle of paying road tax repeatedly during its operational life.
Commercial 2W/4W & Bus Road Tax
For motorcycles, taxis, maxi cabs, or motor cabs with a maximum seating capacity of up to 12 passengers, the applicable road tax is calculated based on the vehicle’s value, exactly like the private vehicles we discussed earlier. It means you are required to pay 8%, 9%, 10%, or 12% of the ex-showroom price as road tax.
