The government has extended the cut-off date for linking Aadhaar with Permanent Account Number (PAN) to September 30, 2019. However, it would be mandatory to quote and link Aadhaar number while filing the return of income from April 1, 2019 unless specifically exempted.“The matter has been considered by the Central Government and now the cut-off date for intimating the Aadhaar number and linking PAN with Aadhaar is 30.09.2019, unless specifically exempted,” an official statement said on Sunday. The government’s statement comes in the wake of reports that PANs not linked with Aadhaar number by March 31, 2019 may be invalidated.
