Aadhaar-PAN linking is mandatory and can be done easily through two main methods:
- Online via the Income Tax e-filing portal (incometax.gov.in): Use the "Link Aadhaar" quick link, enter your PAN and Aadhaar, and validate with the OTP sent to your Aadhaar-registered mobile number.
- Via SMS: Send a text in the format UIDPAN <12-digit Aadhaar> <10-digit PAN> to 567678 or 56161 from your Aadhaar-registered mobile number.
A fee of ₹1,000 is generally applicable for late linking. Ensure your personal details (name, date of birth, and gender) match exactly on both documents for successful linking.
