I think that now token taxes for Punjab province can be paid online. Details available at https://epay.punjab.gov.pk/
If you own a Lahore registered car, you need not pay the token tax in Lahore only. It can be paid in any city of Punjab, like Rawalpindi, etc.
Then, when online system is there; it eliminates the needs for going to even any office too.
Just download the App, follow the instructions, generate the payment ID, pay the token tax via different available channels, and you are good to go.
