Many NRIs discover a serious issue only when they try to file their tax return or check a refund. Their PAN status shows as inoperative. There is usually no prior warning. No email or notification. But by the time you see it, parts of your financial activity in India may already be affected. This is not an uncommon situation. A large number of PANs have become inoperative due to compliance rules, and NRIs are among the most affected groups.
