Rto India — Should i pay Road Tax for Bike.

Address:

Bangalore, Karnataka, 560003

I work in IT company, work will be in between metro cities and every year i will be moving to new city.
So should i pay Road Tax in all the states to use my bike and how can i pay lifetime Road tax when i leave for few months in particular city.
In case if its compulsory then open a online portal to pay road tax and also with months or years package.

Please take this concern seriously.
