Link Aadhaar with Pan Despite the income tax department having extended the deadline to link PAN (Permanent Account Number) card with Aadhaar card for eight times in the past, more than 17 crore PAN card holders are yet to link the two documents. After amendment in the Finance Bill, 2019, the income tax department has the authority to make all such PAN cards which are not linked to Aadhaar inoperative. The due date to link the 10-digit alphanumeric number issued by the income tax department with UIDAI's 12-digit identification number has been extended from 31 December 2019 to 31 March 2020. India has more than 48 crore PAN card holders while more than 120 crore Indians own Aadhaar cards. If you are not sure whether your PAN is linked to Aadhaar, you can check the status here.
