Instant PAN via Aadhaar enables automatic PAN allotment when Aadhaar linkage and identity conditions are satisfied. The Income tax Department's e filing portal now allots a PAN through Aadhaar authentication provided the applicant has never been allotted a PAN, the mobile number is linked with Aadhaar, the complete date of birth is present on Aadhaar, and the applicant is not a minor at the time of application.
