Bihar Road Tax
In India, road tax is levied by the respective state governments on individuals for the use of their vehicle on public roads. The imposition of tax varies from state to state due to different tax rates set by the particular state government based on vehicles. Road tax has to be paid by vehicle owners at the time of registering their vehicles with the Regional Transport Office. In this article, we explore the various aspects of Bihar Road Tax in detail.
Bihar Vehicle Tax Act, 1979
As per the provisions under the Bihar Vehicle Tax Act, 1979, the transport department is responsible for collecting road tax from vehicle owners in the state.

The registered vehicle owner or any individual who owns a vehicle must fill a form stating the particulars of the vehicle and its use in the state to the taxation authority.

Time Limit of Tax Payment
The tax levied under the Motor Vehicle Act, 1988, must be paid at the time of registration of the vehicle. In the case of an old motor vehicle, if the fee (tax) payable for the lifetime of the vehicle has to be paid, it must be completed within thirty days from the expiration date of the previous tax paid. If non-payment occurs, a penalty may be imposed, as discussed here.
Penalty for Non-Payment of Tax
If a taxpayer fails to pay the road tax within the specified time limit, the assessing authority may impose a penalty of the prescribed amount with interest immediately. It is crucial to ensure timely tax payments to avoid penalties and additional interest charges.
Refund of Tax Paid
If there is any excess tax paid, a refund can be claimed by submitting an application form along with the required documents to the taxation authority. After verification with the submitted particulars, the taxation authority will issue a refund voucher in the prescribed form to the taxpayer.
