As of January 1, 2026, the deadline for linking Permanent Account Number (PAN) cards with Aadhaar has passed, with no official extension announced. Taxpayers who failed to link their cards by December 31, 2025, risk their PAN becoming inoperative, impacting financial and tax transactions. While linking is still possible after the deadline, it requires paying a Rs 1,000 late fee. Those who obtained PAN after October 1, 2024, using Aadhaar enrolment are exempt from this fee until December 31, 2025. An inoperative PAN can hinder bank account operations, tax filings, and high-value transactions.
