The government on Sunday extended the deadline for linking PAN with biometric ID Aadhaar by six months till September 30, an official statement said.

This is the sixth time the government has extended the deadline for individuals to link their Permanent Account Number to Aadhaar.

In June last year, the government had said that PAN has to be linked with the biometric ID by March 31.

"Now the cut-off date for intimating the Aadhaar number and linking PAN with Aadhaar is September 30, 2019, unless specifically exempted," the Central Board of Direct Taxes said in a statement.

However, quoting of Aadhaar will be mandatory while filing income tax returns with effect from April 1, 2019.

The CBDT said there were reports that those PANs which are not linked with Aadhaar number by March 31 may be invalidated, following which the matter was considered by the government and the date extended till September 30.
