Permanent Account Number (PAN) will become inoperative if it is not linked with Aadhaar by March 31, 2020, the Income Tax department has said.

The deadline for linking of PAN and Aadhaar has been extended several times and the current deadline ends on 31 March 2020.

Till January 27, 2020, over 30.75 crore PANs have already been linked to Aadhaar. However, 17.58 crore PANs are yet to be linked with the 12-digit biometric ID and may become inoperative if not linked with the Aadhaar by end of March.

“Where a person, who has been allotted the permanent account number as on July 1, 2017, and is required to intimate his Aadhaar number under sub-section (2) of section 139AA, has failed to intimate the same on or before March 31, 2020, the permanent account number of such person shall become inoperative immediately after the said date for the purposes of furnishing, intimating or quoting under the Act,” the Central Board of Direct Taxes (CBDT) said.

Through a notification, the CBDT amended Income Tax rules and inserted Rule 114, stipulating the “manner of making permanent account number inoperative”.

The notification said that persons whose PANs become inoperative shall be liable for all the consequences under the I-T Act for not furnishing, intimating or quoting the permanent account number.

For those linking PAN with Aadhaar after March 31, 2020, the I-T department said it shall “become operative from the date of intimation of Aadhaar number”.

Section 139 AA (2) of the Income Tax Act says that every person having PAN as on July 1, 2017, and eligible to obtain Aadhaar, must intimate his Aadhaar number to the tax authorities.

The Supreme Court had in September 2018 declared Aadhaar as constitutionally valid and held that the biometric ID would remain mandatory for the filing of income tax returns and allotment of PAN cards.

The CBDT had extended the due date for linking of PAN with Aadhaar from 31st December 2019 to 31st March 2020.

Earlier, the deadline for this linkage was September 30, 2019.

Aadhaar is issued by the Unique Identification Authority of India (UIDAI) to a resident of India and PAN is a 10-digit alphanumeric number allotted by the I-T Department to a person, firm or entity.
