The Income Tax department has launched an e-facility to link an individuals’s Aadhaar number with the Permanent Account Number (PAN). The government had recently made it compulsory to link the Aadhaar with the PAN for filing of income tax returns, beginning July 1. Your PAN card could be rendered invalid by December this year if you don’t link it. Under the amendments of the Finance Act 2017, the government made it mandatory for taxpayers to quote the Aadhaar for filing of income tax returns. From July 1 onwards, Aadhar has been made compulsory for applying for PAN as well.
