Taxpayers are reminded that the deadline to link their PAN with Aadhaar is December 31, 2025. Failure to link by this date may result in the PAN becoming inoperative from January 1, 2026, potentially disrupting financial services, tax filings, and banking transactions. A penalty of Rs 1,000 may apply for late linking, though individuals who obtained PAN using Aadhaar enrolment ID before October 1, 2024, have until December 31, 2025, to link for free. The process can be completed online via the Income Tax e-Filing portal.
