Why is Aadhaar-PAN linking important?

Section 139AA of the Income Tax Act states that any individual assigned a PAN as of 1 July 2017, and eligible for an Aadhaar number, must inform their Aadhaar number using the specified form and procedure. Your PAN will become inoperative if you do not link it with Aadhaar by the deadline, the I-T Department said in a user manual.

Notably, Aadhaar-PAN linking is automatically completed during the application process for new PAN card applicants.

The Link Aadhaar service is available to individual taxpayers (both registered and unregistered on the e-Filing Portal).
