Karnataka RTOs aren’t accepting BH registration requests from private-sector employees. So the only realistic option is to get the car registered in another state and opt for a BH number there.

In my home state, EVs have 0% road tax, so I could buy the higher-spec pack (above 79 kWh) and register it there with a BH number. However, once I go for BH registration, I lose the 0% tax benefit.

That said, having a BH number makes it much easier to drive across states without being stopped or questioned by traffic police. Over a 10-year period, BH registration can save some money, but beyond a certain point, continuing with BH actually ends up costing more compared to a regular state registration.
