The IT Dept had been asking people to link their PAN no. with Aadhar before 31 July and many were finding it difficult as their names did not match in both. ( Eg. Names with initials in one and expanded initials in another). Responding to complaints, the IT dept has come out with a simple solution now.
Just go to their www.incometaxindiaefiling.gov.in website and log in. Then go to Profile settings and choose Aadhar linking. Then enter Aadhar no. and ENTER NAME AS GIVEN IN AADHAR CARD. Then both get linked and u will get a confirmation about its success to ur email too. This is a simpler process than several other methods tried earlier.
Please note that matching of PAN and Aadhar is inevitable for GST also.
