1. Before getting the GST Registration there was name as N. AAA in both Aadhaar and PAN.
2. After getting the GST certification but before to upload the Bank Account Details in GST Portal, the initial has been changed from N. AAA to K. AAA. ( Before Certification initial as her father name, after Certification initial as her husband's name)
This initial changed both in Aadhaar and PAN card.
3. In this situation, how can we add the Bank account details in GST portal.
Date of birth , name , father name these can be different in PAN and aadhaar and that's why many were unable to link aadhaar with PAN..
Coming to the query, better to apply for amendment in GST registration since Legal name is already alloted to GST which is changed in PAN and Aadhaar .
