for 2020 -2021 there is an error of WHT which does not appear online.
Only an excise counter at NBP designated branches will be able to help. It happened for a Honda City 2018 which is 3 years old. For tax payment in July 2020 there was no WHT charges.
This year it appeared under arrear, cleared paid at NBP Kandawalla Building Branch (next to demolished nishat cinema) on M.A Jinnah Road.
