You are right, I went to Islamabad GPO for token renewal for Liana 1328 CC, 2011 model. Last year I paid Rs.3348. This time when I went there after waiting for an hour the GPO guy said that token rates are revised and as a Non-Filer you must pay Rs.9348 (Arrears WHT 3000 + 2015-2016 WHT 3000 + Regular Tax 3348). I came back as I was running short of money. Then next week I again went there having 10,000 in my pocket but after waiting in a queue for around 2 hours they GPO guy said that we got a notification from govt yesterday and now you have to pay 10,848 (Arrears WHT 3000 + 2015- 2016 WHT 7500 + Tax 348). Once again, I was running short of money as I took 10k with me.
But today, finally I got my token renew after paying them Rs. 10,848/-.
See the difference, last time it was Rs. 3348 and this year 10,848, a notable difference of Rs. 7500 just in a year. And after paying all this you still have to face a lot of khawari in queues and broken roads every where in Pakistan except few urban areas.
