The Income Tax Department has bought an online help in order to correct mistakes in permanent account number (PAN) and Aadhaar. Along with asking to connect biometric identifier Aadhaar with PAN, the income tax department also laid two other links – 1. To update alterations in existing PAN or to apply for a new PAN. 2. The second link is for the ones wanting to update Aadhaar data by signing into ‘Aadhaar Self Service Update Portal’. The person can then upload the scanned documents providing a proof for data update call.
