Uttar Pradesh has a price-based road tax on private cars, with a level of 3 per cent for the lowest cost of the vehicle up to 6 lakh and an increment to approximately 6 per cent and above or a bit higher with the rise in price of the vehicle. In the case of two-wheelers and other vehicles, tax is dependent on the cost and category; in this case, the exact rate depends on the said details.
3. Is RTO a tax?
Yes, by road/vehicle tax, people mean the state road tax when the vehicle is registered or purchased in the Regional Transport Office (the RTO). It is a tax that is levied by state governments upon the registration and ownership of vehicles.
4. What is the most affordable RTO (state)?
There’s no simple answer. Cheapest is based on your kind of vehicle, price as well as your tax brackets by state. As an example, when a state has low percentage slabs for cheaper vehicles (or discounts for smaller vehicles), the state would have lower taxes. Some of the relatively cheaper states with comparatively low prices on small cars or two-wheelers may turn out cheaper when compared to popular states. Never buy slabs without checking their current price.
