I went through the process of changing my PAN card a couple of years ago and my Singapore address is correctly reflected on my on-line PAN card profile. However, the Form No.16A still reflects my old Chennai address with the notation "Name and address is as present in Income Tax PAN database.Apply for PAN change request to update details". Why should I again apply for update and pay about Rs.1,000/- when the error is obviously due to some system problem in PAN ? Please advise me who I should contact to resolve this problem.
